IMPORTANT INFORMATIO N

ON VEHICLE LOADIN G

OVERLOADING

CAUTION

The components of your vehicle are designed to provide satisfactor y service if the vehicle is not loade d in excess of either the Gros s

Vehicle Weight Rating (GVWR) or the maximum Front and Rear Gross

Axle Weight Ratings (GAWR's ) specified on the vehicle identificatio n number (VIN) plate located behin d the right front access door.

Overloading can create seriou s potential safety hazards and can als o shorten the service life of you r vehicle . Your dealer can advise you concerning proper loading condition s of your vehicle.

MAXIMUM FRONT AND REAR AXLE

WEIGHTS (AS MANUFACTURED)

The weight of the cargoload must b e properly distributed over both the fron t and rear axles, although not necessarily evenly . The (VIN) plate shows the maximum weight that the front axle can carry (front GAWR) and the maximu m weight that the rear axle (rear GAWR) can carry . The GVWR represents the maximum permissible loaded weight of the vehicl e and takes into consideration the engine , transmission, frame, brake, axle and tir e capabilities . Actual front and rear en d weights at the ground can only b e determined by weighing the vehicle . This can be accomplished through highway weigh stations or other such commercial facilities .

To lock door from inside vehicle, pus h the lock button DOWN . To unlock and open door from the inside, pull the lock button UP and pull on inside door handle .

LAP BELTS

Your vehicle is equipped with lap belt s in the driver and front passenger seatin g position(s) . It is recommended that while the vehicle is in motion, all occupant s remain seated and keep lap belts buckle d snugly at all times .

The front outboard seating positions—hav e

retractors which are designed t o automatically take up excess webbing .

• Adjust seat to your satisfaction and sit erect and well back in the seat .

• In a single motion, pull webbing acros s lap far enough to permit inserting meta l latch plate end of lap belt into th e buckle, until a snap is heard . If webbing

Entrance Door Latch

is not pulled out far enough to reach the buckle, let the belt rewind into th e retractor to release lock mechanism, s o belt can be pulled out to the prope r length .

• Position lap belt across lap as LOW O N

HIPS as possible . To reduce the risk o f sliding under the belt during an accident , adjust to a SNUG FIT by pulling bel t firmly across lap in direction of retracto r so it can take up slack .

NOTE : Take care not to let the lap bel t twist while it is being rewound into th e retractor . The bulk of the twisted bel t may cause the retractor to jam so it wil l not rewind further, while at the same tim e the retractor's locking mechanism may prevent the belt from being withdrawn . I f a belt should become jammed, you may be able to release it by working the belt i n or out until the belt rewinds far enoug h to unlock . If lap belt remains jammed o r other parts of the restraint system do no t operate properly take the vehicle to you r dealer for service .

CAUTION

A snug fit and a low

lap

bel t position are essential to lessen the chance of injury in the event of a n accident, because this spreads th e

7

Lap Belt (Front Seating Position )

force

exerted by the

lep belt in a collision over the strong hip bone structure rather than across the soft abdominal area . To help lessen the chance of injury in the event of a n accident : Never use the same bel t for more than one person at a time ; avoid wearing belts in a twisted condition ; do not allow belts or hardware to become damaged b y being pinched between the seat structural (metallic) members or in the door .

Inboard seating position, front dua l passenger seat (if so equipped)—should

b e positioned and secured as above, and adjusted to a SNUG FIT by pulling o n the end of the belt extending from the adjustable latch plate .

• To lengthen the lap belts at these seating positions, place adjustable latc h plate at right angle to the belt webbing and pull on latch plate ; belt should the n slide easily through the adjustmen t feature .

• To unfasten seat belts, depress push button in center of buckle .

• When no longer in use, front outboard lap belts can be stowed by allowin g them to rewind into their retractors .

LAP BELT INSPECTIO N

• Periodically inspect belts, buckles, latch plates, retractors, and anchors for damage that could lessen the effectiveness of the restraint system .

• Keep sharp edges and damaging object s away from belts and other parts of th e restraint system .

• Replace belts if cut, weakened, frayed , or subjected to collision loads .

• Check that the anchor mounting bolt s are tight .

• Have questionable parts replaced .

• Keep belts clean and dry.

• Clean only with mild soap solution an d lukewarm water .

• Do not bleach or dye belts since this may severely weaken them .

CHILD RESTRAINT

Children in vehicles should be restraine d to lessen the risk of injury in accidents, o r sudden stops . In using any infant or chil d restraint system, read and comply with al l installation and usage instructions .

All unused lap belts near the child should be stowed properly to help prevent them from striking the child in the event of an accident . Lap belts without storag e provisions should have buckles latched an d belts adjusted to remove slack .

If a child is traveling in a vehicle no t equipped with an appropriate infant o r child restraint system, the followin g precautions should be taken :

1 . Infants unable to sit up by themselve s should be restrained by placing them in a covered padded bassinet placed crossways in the vehicle (widthwise) o n the seat . The bassinet should be securely restrained with the regular vehicle la p belts .

8

2 . Children able to sit up by themselves should be placed on a seat and la p belted . Never allow a child to stand o r kneel on any seat or elsewhere in the vehicle, once it is underway .

CAUTION S

1. Trailer brakes are required o n trailers over 1,000 lbs . loade d weight.

2. DO NOT tap into vehicle' s hydraulic brake system i f operation of the trailer brak e system requires more than 0 .02

cu : in . of fluid displacement fro m the vehicle's master cylinder . The vehicle' s master cylinder flui d capacity will not be sufficient to operate both vehicle and traile r brakes under all conditions of us e if more than 0 .02

cu : in . of fluid displacement is required .

3. Whenever a trailer hitch i s removed, be certain to have any mounting holes in underbod y properly sealed to prevent possibl e entry of exhaust fumes, dirt o r water . (See "ENGINE EXHAUS T

GAS CAUTION" in the following section .)

TRAILER HAULIN G

Towing a trailer will affect handling , durability and economy . Maximum safety and satisfaction depends upon proper use of correct equipment and avoiding overload s and other abusive operation .

The maximum loaded trailer weight which you can pull with your vehicle depends on what special equipment has been installed . GMC does not recommen d towing any trailer OVER 1,000 POUND S

GROSS TRAILER WEIGHT .

To assist in attaining good handling o f the Vehicle Trailer Combination, it i s important that the trailer tongue load b e maintained at approximately 10% of th e loaded trailer weight . Tongue loads can b e adjusted by proper distribution of the loa d in the trailer, and can be checked b y weighing separately the loaded trailer and then the tongue .

The allowable passenger and cargo load

(GVW) of this vehicle is reduced by a n amount equal to the trailer tongue load on the trailer hitch .

OPERATION I N

FOREIGN COUNTRIE S

Your vehicle's engine is designed t o operate on unleaded fuel of approximatel y

91 research octane number .

If you plan to operate your vehicl e outside the continental limits of the Unite d

States or Canada, there is a possibility tha t the best fuels available are so low i n anti-knock quality that excessive knockin g and serious engine damage may result from their use . To obtain information on the quality of fuels available in the countrie s in which you plan to travel write to GM C

Truck & Coach Division, General Motor s

Corporation, Pontiac, Michigan 48053 (or i n

SECTION 2

STARTING AND OPERATING VEHICL E

ENGINE EXHAUST GAS CAUTIO N

(CARBON MONOXIDE )

Avoid inhaling exhaust gases because they contain carbon monoxide, which b y itself is colorless and odorless . Carbon monoxide is a dangerous gas that can cause unconsciousness and is potentially lethal .

If, at any time, you suspect that exhaust fumes are entering the vehicl e from any source have the cause determined and corrected as soon as possible .

If you must drive before the cause is corrected, drive only with ALL window s

FULLY open and heating or cooling system adjusted for maximum ventilatio n

(see below) .

The best protection against carbon monoxide entry into the vehicle body is a properly maintained engine exhaust system, body and body ventilation system .

It is recommended that the exhaust system and body be inspected by a competent mechanic :

• Each time the vehicle is raised for lubrication or oil change .

• Whenever a change is noticed in the sound, alignment, or appearance of th e exhaust system .

• Whenever the exhaust system, underbody or rear of the vehicle is damage

See your Maintenance Schedule folder for inspection procedure .

To allow proper operation of the vehicle's ventilation system, keep front inlet grille clear of snow, leaves, or other obstructions at all times .

OCCUPYING A PARKED VEHICLE WITH ENGINE RUNNING FOR A N

EXTENDED PERIOD OF TIME IS NOT RECOMMENDED .

Do not run engine in confined areas such as garages any more than neede d to move vehicle in or out of area . When vehicle is stopped in an

UNCONFINED area with the engine running for any more than a short perio d of time, adjust heating or cooling system to force outside air into the vehicle as follows :

1 .On vehicles not equipped with automotive air conditioning, set fan t o medium or high speed and upper control lever to any position except

"OFF . "

2 .On vehicles equipped with automotive Air Conditioning, set fan to mediu m or high speed and upper control lever to any position except "OFF" .

The two rear windows (if so equipped) should be closed while driving t o avoid drawing dangerous exhaust gases into the vehicle through those openings .

In addition, it is recommended that roof vent(s) be closed while driving. If, fo r some reason, a rear window or roof vent must remain open for a period whil e driving, or electrical wiring or other cable connections to a trailer must pas s through the seal between them and the body, the following precautions shoul d be observed .

• Close all windows.

• Adjust heating or cooling system to force outside air into the vehicle a s described in Step 1 or 2 above but with fan set at high speed .

• Air vents in or under the instrument panel should be fully open .

It is important that the inside engine cover be properly seated to prevent possible leakage of exhaust fumes into the vehicle through this opening .

The kick-up panel at the rear of the floor (see illustration) contains hole s which may be utilized to facilitate access to the interior for installation o f certain interior equipment (i .e ., access for wiring, plumbing, etc.) The holes should be plugged and sealed to avoid possible exhaust gas (carbon monoxide ) intrusion into the interior of the vehicle .

Whenever operating the optional motor-generator it is essential the left-rea r window (if so equipped) of the vehicle be kept closed to prevent possibl e entry of motor-generator exhaust gases into vehicle . Inspect the motor-generator exhaust system at vehicle lubrication intervals or when a change is noticed i n the sound, alignment, or appearance of the exhaust system or if it is damaged .

Do not run motor-generator in a confined area, such as a garage .

NOTE : Particular care should be taken to prevent the possibility of carbo n monoxide exposure when the vehicle is modified for recreational or other usage .

Additionally, some recreational vehicle appliances (such as lights, refrigerators , stoves, heaters) may generate carbon monoxide and should be used only if there is adequate ventilation .

STARTING ENGIN E

1. Apply the parking brake .

2. Place the transmission selector in "P" or "N" ("P" is preferred) . A starter safet y switch is designed to prevent starte r operation while the transmission selector i s in any drive position . (If it is necessary t o re-start the engine with the vehicle moving , place the selector lever in "N" . )

3.

Depress accelerator pedal and activat e starter as outlined in the following, fo r different conditions .

Transmission Shift Indicato r and Speedometer

COLD ENGIN E

Fully depress accelerator pedal an d slowly release . With foot off the pedal, crank the engine by turning the ignition key to the "START" position— releas e when engine starts. If engine starts bu t fails to run, repeat this procedure . When engine is running smoothly (approx . 30 seconds) the idle speed may be reduced by slightly depressing the accelerator pedal and then slowly releasing .

CAUTIO N

Extended running of the engine ( 5 minutes or more) without depressin g the accelerator pedal, could cause damage to the engine or exhaust system due to overheating.

EXTREMELY COLD WEATHER (BELOW 0° F .)

(-18° C .) OR AFTER VEHICLE HAS BEE N

STANDING IDLE FOR SEVERAL DAY S

Fully depress and release accelerato r pedal two or three times before crankin g the engine . With foot off the accelerato r pedal, crank the engine by turning the ke y to the start position—release key whe n engine starts .

IF ENGINE FAILS TO START :

• First, fully depress and release th e accelerator pedal several times, the n remove foot from accelerator pedal and crank engine .

• If engine still does not start, full y depress the accelerator pedal and hold t o the floor while cranking the engine .

• If the engine has been flooded wit h gasoline, it may start to run but no t have enough power to keep running . In this case, continue cranking with the accelerator pedal fully depressed until the engine cleans itself of excess gasoline and runs smoothly .

WARM ENGIN E

Depress accelerator pedal about halfwa y and hold while cranking the engine .

• If engine doesn't crank properly due to a discharged main battery (automotiv e battery), place the battery switch in th e

"BAT BOOST" position . Return the switch to the "BAT NORMAL" positio n when engine starts .

Turn Signal Lever

NOTE : Do not continue cranking th e engine for more than 30 seconds at a tim e to prevent starter overheating .

AUTOMATIC TRANSMISSIO N

The transmission selector lever is located o n the right side of the steering column and th e shift indicator is located in the bottom sectio n of the speedometer cluster on the dash .

• "PARK"—Transmission lock when parkin g or while starting the engine . Pull the selector lever towards you to select o r release this position . Never move th e selector lever to "PARK" position unles s the vehicle is completely stopped .

"NEUTRAL" is the only other positio n in which your vehicle may be started .

• REVERSE "R"—For backing the vehicle .

Bring the vehicle to a complete sto p before moving the selector lever int o

Reverse .

• NEUTRAL "N"—The out-of-gear position .

It is provided for starting a stalled engine while the vehicle is in motion or running the engine while standing wit h brake applied . DO NOT COAST I N

NEUTRAL.

• DRIVE RANGE "D"—The driving rang e for city and highway driving . This position permits the transmission t o operate through its complete range o f gear ratios and to select automaticall y the proper ratio for road and loa d conditions .

14

• SUPER RANGE "S"—Used when super performance is needed for increase d acceleration in traffic, hill climbing, or

"Engine Braking" down-hill . The selector lever may be moved from "D" to "S " and vice versa, under most operating conditions . "SUPER" should not be used at speeds above 75 MPH .

• LOW

" L"—Available for heavy pulling through mud or sand and for engin e braking when descending steep hills . The selector lever may be moved to "L" a t any speed but the transmission will only shift automatically into Low range whe n the vehicle speed is under approximatel y

40 MPH . The transmission will not upshift from Low range as long as th e selector lever is in the "L" position .

CAUTIO N

Before descending a steep or long grade, down a mountain or hillside , reduce speed and shift into a lower gear . Use the lower gear ranges t o control vehicle speed . Avoid prolonged or frequent application o f the brakes which could caus e overheating and thus reduce brak e effectiveness. Use caution when shifting into lower range or lowe r gear on slippery surfaces with vehicle moving—abrupt engine brakin g action could cause the front wheel s to skid, possibly leading to loss of vehicle control .

• FORCED DOWNSHIFT—When additiona l acceleration is desired to pass movin g vehicles or to climb steep grades at speeds between approximately 35 and 6 5

MPH, the transmission can be downshifted by depressing the accelerator pedal completely to the floor . It is also possible to obtain a forced downshift in

"DRIVE" range at speeds under 35 MP H by depressing the accelerator pedal part way down .

TURN SIGNAL AN D

LANE CHANGE FEATUR E

Whenever a right or left turn is intended, when changing lanes, or when pulling away from the curb, use the turn signals .

• FULL TURN—For normal turns, mov e the turn signal lever to position "A" for right turn and "B" for left turn . Lever will remain in position without manua l effort until the turn is completed, the n cancel automatically .

• LANE CHANGE—Move lever to th e detent position "C " for change to righ t lane or to "D" for change to left lane .

Hold lever in position until lan e maneuver is completed, then release .

CAUTIO N

This vehicle is equipped with a Dual Hydraulic Split System With Power Assist . I t is also equipped with disc type brake s on the front wheels and drum type brake s on the tandem rear wheels .

NOTE : Operation of the brake system warning light is covered (on page 21) (in the section on "Instrument Panel an d

Controls.")

Driving through deep water may wet the brakes and adversely affect brake performance so that th e vehicle will not slow down at th e usual rate, and may pull to the right or left . Applying the brake s lightly will indicate whether the y have been so affected . To dry the m quickly, lightly apply the brake s while maintaining a safe forwar d speed with an assured clear distance ahead until brake performanc e returns to normal .

17

Parking Brake Contro l

• On your vehicle, if power assist to th e brakes is interrupted due to a stalle d engine or some malfunction, two o r more brake applications can normally b e made using reserve power .

• If the brake pedal is held down, th e system is designed to bring the vehicl e to a full stop on reserve power .

However, the reserve power is partiall y depleted each time the brake pedal is applied and released . Do not pum p brakes when brake power assist has been interrupted, except when necessary in order to maintain steering control o n slippery surfaces .

•When reserve power is exhausted, the vehicle can still be stopped by applying greater force to the pedal .

SELF-ADJUSTING BRAKE S

Brakes on this vehicle (except for th e

Parking Brake) are self-adjusting, designe d to eliminate periodic adjustments .

Drum brake adjustments are made automatically as the brakes are applied while vehicle is moving backwards .

Disc brake adjustment is made automatically with each brake application .

18

• If excess brake pedal travel develops , drive alternately backward and forward several times and apply brakes firmly i n each direction .

• See your dealer if normal pedal travel i s not restored, or if there is a rapi d increase in pedal travel, which could b e a sign of other brake trouble . See you r dealer also if adjustment of the parkin g brake is required .

NOTE : "Riding The Brake" by restin g your foot on the brake pedal when no t intending to brake can cause abnormally high brake temperatures, excessive lining wear and possible damage to brakes in addition to wasting gasoline .

REMINDER :

Front disc brakes have a built-in wear indicator that is designed to make a high frequency, squealing, or cricket-like warning sound when the lining s are worn to where replacement is required .

The sound will occur intermittently o r continuously when wheels are rolling, bu t will disappear when the brake pedal i s applied firmly . See also the various brak e checks listed in the maintenance schedule folder.

PARKING BRAK E

• To set parking brake, pull up the handl e located on the floor against the left wall, below the instrument panel .

• For increased holding power, first depres s regular brake pedal with the right foot , and hold it while setting the parking brake with left hand .

• To release parking brake push the handl e down .

• As a reminder, the "PARK BRAKE " reminder light is designed to come o n whenever the parking brake control i s not fully released, and the ignition i s on .

• Never drive vehicle with parking brak e set as this may overheat or otherwis e damage rear brakes .

The amount of force required to apply parking brake can be adjusted by turning a tension adjustment knob located at th e upper end of the lever . This also adjust s the degree of brake application . The greater the force required at the lever the greater the degree of brake application .

NOTE : The parking brake should be se t first whenever the driver's seat is left unattended .

If the vehicle is parked on a grade an d the transmission is placed in "PARK" before the parking brake is set, the weigh t of the vehicle may exert so much forc e on the parking pawl in the transmissio n that the transmission selector lever canno t later be pulled out of "PARK ." T o prevent this, the parking brake should b e applied BEFORE moving the transmissio n selector lever to "PARK ." When preparing to move the vehicle, the shift indicator should be moved out of the "PARK " position BEFORE releasing the parking brake . It is good driving practice to se t the parking brake first, and release th e transmission from "PARK" first at all times, even on the level. If "torque lock" , as this condition is called, does occur, it may be necessary to have another vehicle nudge this vehicle up hill, to take some o f the pressure off the transmission while th e driver pulls on the transmission selecto r lever .

HEADLIGHT DIMMER SWITC H

To obtain high or low beam headlights , push the foot dimmer switch located o n the floor to the left of the brake pedal .

Each time the switch is depressed, the light beam changes . A headlamp beam indicator, on the face of the speedometer , is designed to light up when the headlight s are on high beam .

HEADLIGHT "FLICKER "

The headlight circuits are protected by a circuit breaker in the light switch . An overload on the breaker will cause th e lights . to "flicker" on and off, or in some cases to remain off. If this condition developes, have your headlight electrica l circuit checked immediately .

INSTRUMENT PANEL AND CONTROL S

SPEEDOMETER AND ODOMETE R

The speedometer indicates the forward spee d of the vehicle in miles-per-hour and kilometer s per hour . The odometer registers th e accumulated mileage the vehicle has been driven .

Also, located in the speedometer cluster are th e turn signal indicators which show direction an d proper operation of the turn signals, the hig h beam indicator light, and the shift indicator .

FUEL GAUG E

This gauge shows the approximate fue l level in the main tank when fuel selector switch is in the "FUEL MAIN" position, and the fuel level in the auxiliary tank when fuel selector switch is in the "FUE L

AUX" position . The pointer will indicat e the correct positions only when th e ignition is in the "ON" position .

Since both fuel tanks are interconnected , the indicated level is designed to read th e same (with the switch in either position) until approximately 60% of the total fuel capacity has been used . See "Fuel Selector

Switch " later in this section .

TEMPERATURE GAUGE

This gauge registers the temperature o f the engine coolant . The center area of the water temperature gauge marks the norma l operating range . However, if the needle moves beyond the center area marks int o the "H" side or hot area of the gauge , stop the engine as soon as possible, an d remain stopped until the cause of th e overheating is determined .

OIL PRESSURE GAUGE

This gauge registers engine oil pressure.

The consistency of the oil in a coo l engine will cause a high reading when the engine is first started . As the engin e warms, the pressure will recede to normal .

With the engine warmed up to norma l operating temperature,_ minimum pressure a t idle should be slightly above the

" L " graduation (8 PSI) . At normal operating speeds, minimum pressure should be

2 0

between the second and middle graduation s

(35 PSI) . Should the pressure drop belo w these minimums, stop the engin e immediately and check the cause of the low oil pressure . This could be the resul t of a dangerously low oil level in th e crankcase . Driving the vehicle with low oi l pressure can cause extensive engine damage .

CHARGING SYSTEM WARNING LIGH T

Located to the right of the temperatur e gauge is the charging system warning light .

A red light "GEN" will appear with th e ignition key in the "ON" position and th e engine not running . This light lets yo u know the warning signal is operational .

Should the light fail to come on, see you r

MotorHome dealer . When the engine is started , the warning light should go out and remain out .

If the light remains on when engine is running, have your dealer locate and correct the troubl e as soon as possible .

BRAKE SYSTEM WARNING LIGH T

The service brake system is a dual system designed so that one part wil l provide some braking action in the even t of loss of hydraulic pressure in the othe r part of the system . If the red warning light, located to the left of the oil pressure gauge, comes on and stays o n when the ignition is on and after the brakes have been firmly applied, it may indicate that there is a malfunction in on e part of the brake system .

• As a check on bulb condition the ligh t should glow during engine starting .

• Have system repaired if light does no t come on during check .

• This warning light is not a substitute for the visual check of brake fluid leve l required as part of normal maintenance .

WHAT TO DO IF LIGHT COMES ON :

• The service brake system is partially inoperative .

Warning Light Cluster

1 .

Pull off the road and stop , carefully—remembering that :

• Stopping distances may be greater .

• Greater pedal effort may be required .

• Pedal travel may be greater.

2 . Try out brake operation by startin g and stopping on shoulder of road—then :

• If you judge such operation to be safe , proceed cautiously .at a safe speed t o nearest service outlet for repair, or

• Have vehicle towed to dealer for repair .

Continued operation of the vehicle in this condition is dangerous.

TELL-TALE WARNING LIGHT CLUSTE R

A cluster of indicator lights is locate d just to the left of the heater controls .

These are designed to inform the driver o f the status of certain systems or condition s of which he should be aware . Among thes e are :

• "CRUISE " (Optional Equipment)—Thi s indicator is designed to glow GREEN whenever the Cruise Control System i s engaged and working .

• "DOOR"—The door light is designed t o warn the driver that the entrance doo r is not properly closed .

WINDSHIELD WASHER S

The windshield washers are controlled b y the washer switch located under the windshield wiper lever . To operate the washers, turn the wipers to an O N position, then push down on the switch until the desired amount of washer fluid has been directed to the windshield .

• Check washer fluid level regularly—do it frequently when the weather is bad .

• Use a fluid such as GM OPTIKLEEN t o prevent freezing damage, and to provid e better cleaning .

• Do not use radiator antifreeze i n windshield washer ; it could cause paint damage .

• In cold weather, warm the windshiel d with defrosters before using washer—t o help prevent icing that may seriously obscure vision .

FUEL SELECTOR SWITC H

The fuel selector switch, located belo w the warning light cluster, has tw o positions,--"FUEL MAIN" and "FUE L

AUX . "

This switch allows the driver t o change the fuel pick-up and fuel gauge sending unit from the main tank, as it goes empty, to the auxiliary tank whic h will normally contain 7 to 9 gallons o f fuel. It is recommended that any time the fuel system is filled, this switch be put i n the "FUEL MAIN" position and left ther e until auxiliary fuel is needed .

NORMAL OPERATIO N

The controls consist of three rocker switche s that junction to automatically or manually leve l the vehicle . The center rocker switch

(TRAVEL) is used for a travel or hold mode , and the two outer rocker switche s

(RAISE-LOWER) are used to raise or lower th e vehicle .

28

Driving

A reminder light in the dash panel is designe d to light any time the engine is running and th e transmission selector lever is moved to "D "

(Drive Range) . The normal position for the

RAISE-LOWER switches should be place d in "OFF" . The TRAVEL switch should b e moved to "AUTO" for the first five minutes, if vehicle has been in a raised or lowered position .

Then move the switch to "HOLD" after rid e height is achieved .

It is not necessary to move the TRAVE L switch to "AUTO" if vehicle has not bee n leveled at a campsite or vehicle load has no t changed significantly .

NOTE: The "HOLD" position is to be used fo r normal highway driving, when the vehicle is i n operation . This allows the vehicle to maintain a designed ride height and eliminates unnecessary operation of the air compressor .

CAMPSITE OR PARKING ARE A

The two "RAISE-LOWER" switches may b e used as necessary to raise or lower the vehicle .

When using Electro-Level at a campsite the vehicle engine need not be running to operat e the system, however, the ignition switch must b e in the "ON" or "ACCESSORY" position .

"RAISE"—With a rocker•switch in this positio n the appropriate side of the vehicle will raise rear of vehicle to any desired position, up to a maximum of approximately 4 inches above normal ride height . When desired height is reached, return rocker switch to "OFF" position .

"LOWER"—With a rocker switch in this positio n the appropriate side of the vehicle will lower a maximum of approximately 4 inches below th e normal ride height . In order to maintain a desired height, return rocker switch to "OFF " position.

NOTE : It is possible that the air compressor may operate for a short period when a rocke r switch is in "LOWER" position .

IMPORTANT : When both sides of the vehicl e have been leveled be sure the TRAVEL switch

i s moved to "HOLD" and turn ignition switch t o

"OFF" .

29

A glass of water or a bubble type level whe n placed in a normally level location inside the vehicle can be used to assist in determining the desired level condition .

OFF-ROAD OPERATIO N

In order to gain maximum ground clearanc e both RAISE-LOWER switches should be place d in the "RAISE" position. It is recommende d that a speed of 15 MPH should not be exceede d since the air suspension in this position ha s maximum pressure supplied .

EMERGENCY OPERATIO N

In the event of total air loss for any reason , the vehicle may be driven at a speed of 5-1 5

MPH (depending on road surface) with the rea r of the vehicle in the fully "DOWN" position .

Care should be exercised since ground clearanc e at the rear will be at a minimum . Vehicle should be taken to nearest dealer .

Depending on the type of failure, it may b e possible to add air to the rear suspension we t tank (shop air fill valve located on tank—see illustration) by filling reservoir at a local ga s station (DO NOT EXCEED 120 PSI) .Be sure th e engine is running or the ignition switch is turne d to "ON" or "ACCESSORY" position, and th e outer rocker switches in "RAISE" position unti l vehicle is leveled . Then move RAISE-LOWE R switches to "OFF" and TRAVEL switch to

"HOLD" .

EXTERIOR GLASS

The best way to preserve the finish i s to keep it clean . Normally only frequen t washings are required to maintain it s original beauty . Wash the vehicle wit h either cold or warm (never hot) water, not in the direct rays of the sun and no t while the sheet metal surfaces are hot .

Never wipe dirt from dry painted surface s because this may scratch the finish. Th e use of strong soaps and chemical detergent s should be avoided . Cleaning agents shoul d be promptly flushed from the surface an d not allowed to dry or they may streak th e finish .

Never wipe glass with dry paper o r cloth . Do not operate wipers when glass i s dry . Dirt and insects can be removed wit h clear water or with a mild liquid household cleaner . The use of hars h abrasives should be avoided . Periodi c inspection and replacement of wiper blade s will reduce the possibility of the windshiel d becoming scratched and will assure clea r vision under adverse driving conditions .

POLISHING AND WAXIN G

BRIGHT METAL PART S

Wash all bright metal parts frequently t o alleviate the destructive forces of salt , calcium chloride, salt air, exhaust gases , and industrial fallout (which may be corrosive) .

Even though the acrylic enamel on you r vehicle is durable, under certain condition s it may be advisable to wax or polish you r vehicle to proivde added protection .

Calcium chloride and other salts, road oi l and tar, tree sap, chemicals from factor y chimneys and other foreign matter may damage any known vehicle finish if allowed to remain in contact with the paint film .

Use lukewarm water and mild soap, no t with a strong alkali solution, rins e thoroughly . Avoid use of bright metal polishes containing harmful abrasives .

NOTE :

In severe cases, road oil and ta r may be removed from bright metal parts by a chemical cleaner which is specifie d safe to use on all acrylic finishes .

Prompt washing may not remov e thoroughly these deposits and, particularly in geographical areas where exposure conditions are severe . Properly applied polished and waxes of known quality wil l provide the best protection . Most GM C

MotorHome dealers offer polishes or waxe s which can be of real value in maintaining a good paint finish .

A protective coating such as GM Chrom e

Gard may be applied on clean chrom e surfaces which are stain and rust free . I f necessary, GM Chrome Cleaner and Polis h may be used to remove rust from chrom e plated parts before applying a protective coating .

NOTE :

Some chemical cleaners, used for removing road oil and tars from painte d surfaces, are detrimental to acrylic ename l finishes . When purchasing a cleaner, make sure the instructions on the containe r specifically state that the contents can b e used on any acrylic enamel finish .

43

TOUCH-UP PAIN T

Nicks and chips in paint surfaces shoul d be touched up before weathering actio n begins . The best time to detect them is right after the vehicle has been washed .

Touch-Up Paint to match you vehicle' s color is available at your GMC MotorHom e dealer .

UNDERCOATIN G

Due to the fiberglass and aluminu m body construction of the vehicle adde d protection by additional undercoating is no t necessary . However, if you do wish to apply undercoating material, it should b e kept off of all moving or rotating parts . I t should also be kept off air conditione r fittings, body drain holes, exhaust systems , and plumbing .

LUBRICATION DETAIL S

ENGIN E

ENGINES OIL AND FILTE R

RECOMMENDATION S

• Use only SE engine oil .

• Refer to Maintenance Schedule folder fo r oil change and filter replacemen t intervals.

• See your GMC MotorHome dealer for advice on the frequency of oil and filter changes under unusual driving conditions .

The recommendations in the Maintenanc e

Schedule folder apply to the first chang e as well as subsequent oil changes . The oi l change interval for your vehicle's engine i s based on the use of SE oils and quality oil filters. Oil change intervals longer tha n those listed will seriously reduce engine life and may effect GMC Truck & Coach' s obligation under the provisions of the Ne w

Vehicle Warranty .

A high quality SE oil was installed in your engine at the factory . It is no t necessary to change this factory-installed oil prior to the recommended normal chang e period . However, check the oil level more frequently during the break-in period sinc e higher oil consumption is normal until th e piston rings become seated .

NOTE : Non-detergent and other lo w quality _oils are specifically no t recommended . Only the use of SE engin e oils and proper oil and filter chang e intervals assure you of continued prope r lubrication of your vehicle's engine .

RECOMMENDED SAE VISCOSITY

•

Single grade oils are preferred, however , multigrased such as SAE 10W-30 or

IOW-40 are also acceptable .

• SAE 5W-20 oils ' are not recommend for sustained high speed driving .

•

SAE 5W-30 oils (if available) may b e used if extreme low temperatures are anticipated .

SUPPLEMENTAL ENGINE OIL ADDITIVE S

The regular use of supplemental additive s is specifically not recommended and wil l increase operating costs . However , supplemental additives are available that ca n effectively and economically solve certain specific problems without causing othe r difficulties. For example, if highe r detergency is required to reduce varnish and sludge deposits resulting from som e unusual operational difficulty, a thoroughl y tested and approved additive—"Super Engin e

Oil Supplement"—is available at your GM C

MotorHome dealer . In the event of a n operational problem, consult your dealer for advice before using supplemental additives.

CHASSIS FUSES, FUSIBLE LINKS ,

CIRCUIT BREAKER S

The wiring circuits in your vehicle are designed to be protected from shor t circuits by a combination of fuses, circui t breakers, and fusible thermal links in th e wiring itself. This helps to reduce the hazard of electrically-caused fires in th e vehicle .

The fuse and circuit breaker block is located behind an access cover in the glov e compartment . All chassis circuits are protected by fuses or circuit breaker s located here except :

• HEATER BLOWER—Which has a fusibl e link built into harness located behind th e right access door near the heater blowe r relay .

• HEADLAMP CIRCUITS—Are protected b y a circuit breaker in the main light switch . An electrical overload in the ligh t circuit will cause the lights to go o n and off or in some cases to remain off .

If this condition develops, have th e wiring circuits checked immediately .

Circuit breakers of remote reset type can be reset only after turning the affecte d circuit control switch "OFF" fo r approximately 40 seconds, or by removin g the breaker from clips for this period o f time .

CAUTIO N

Do not touch body of any installe d breaker of this type with bare hands ; if circuit should happen to be shorted or overloaded—the breaker body could be hot and cause a burn .

A replaceable fuse link is located at th e battery pickup junction block behind th e right access door. If an overload shoul d occur, this link is designed to fail (ope n circuit) preventing damage to the main wiring harness . Another link of the sam e wire gauge and length must be installed i n its place in the event of failures .

WHEELS AND TIRE S

TIRE S

The factory installed tires on you r vehicle are designed to provide the best all-around performance for normal vehicl e operation . When inflated as recommended on the "Tire Pressure Placard," located o n the glove compartment door of you r vehicle, the tires have the load carryin g capacity to operate satisfactorily at al l normal highway speeds .

Tire Care

Tires should be checked regularly for proper inflation pressure, wear, and damage .

The following information will assist you i n properly caring for your tires .

Inflation Pressure

Tire inflation pressures listed on the tir e placard have been selected to provide th e best tire life, riding comfort and handlin g stability for normal driving conditions .

Tire Pressure Placard

The use of improper tire inflatio n pressures can adversely affect tire life and vehicle performance . Too little air pressur e can result in excessive tire heat, abnorma l tire wear, adverse vehicle handling an d reduced fuel economy . Too much air pressure can result in abnormal tire wear , adverse vehicle ride and handling, and increased susceptibility to damage by roa d impacts .

61

Tire pressures should be checked at leas t once a month (and preferably more often) or before long trips or when heavily loaded .

The following points should be observe d when checking and setting tire pressures.

1.

Cold tire pressure ratings are applicable when a vehicle has been inoperative for 3 hours, or more, or drive n less than one mile .

2.

Tire inflation pressure may increase a s much as 6 psi when hot (after vehicle ha s been driven 10 miles or at speeds of mor e than 60 MPH) . Do not "bleed" or reduce pressures when tires are hot from driving .

3.

For continuous high speed operatio n

(over 65 MPH), increase tire inflatio n pressure to 70 psi.

4 . Always use a tire pressure gaug e when checking tire pressure .

Tire Damage & Repai r

Tires with cuts, splits or cracks dee p enough to expose the fabric, should b e removed from service . Bulges usually indicate internal damage, and the tire should be removed . Tires with questionable damage should be removed from the whee l and examined by an expert .

If an air loss occurs while driving, d o not attempt to drive on the deflated tir e more than is necessary to stop safely .

Driving even a short distance can damage a tire beyond repair .

Temporary repairs, such as "blowout " patches or any repair made from th e outside of the tire should not be mad e except in emergencies . Such "stop-gap " devices as plugs and aerosol-type sealant s are good for not more than 100 miles o f driving at speeds not over 50 MPH .

A permanent vulcanized repair, plug or patc h applied from inside the tire, should b e made as soon as possible . Also, the installation of an inner tube in a damage d tubless tire is not a recommended repair procedure .

Replacement Tire s

When replacing tires, only the siz e

(8 .75-16.5), load range ("D"), constructio n type bias-ply steel belted) are recommended for installation on the vehicle .

IMPORTANT :

recommended vehicle .

Radial tires are no t

for installation on th e

• To achieve best all-around vehicl e performance, bias-ply and bias-ply stee l belted tires should not be mixed on th e same vehicle .

• It is recommended that new tires b e installed in pairs opposite each othe r

(preferably the front wheels) .

• When replacing only one tire, it shoul d be paired with the tire having the leas t wear, to equalize braking traction .

Replacement Wheel s

Wheels must be replaced if they becom e bent, are heavily rusted, if the lug nut s won't stay tight, or if they leak air .

Straightening bent wheels or using inne r tubes in leaking wheels are no t recommended repair procedures .

When replacing wheels for dealer.

any reason , care should be taken to insure that the wheels are equivalent to those removed in load capacity, diameter, rim width, and offset . Correct replacement wheels can b e obtained from your GMC MotorHom e

Use of any other size or type wheel may adversely affect wheel and wheel bearing life, brake cooling and stopping ability, headlamp aim, speedometer-odomete r accuracy, bumper height, vehicle groun d clearance and tire clearance to the bod y and chassis .

The use of used wheels is also no t recommended ; if they have been ru n overloaded or under other sever operatin g conditions for extended periods, the wheel' s life may have been greatly shortened .

Use of any other tire may seriousl y affect ride, handling, speedometer/odomete r calibration, vehicle ground clearance an d tire clearance to the body and chassis . The following also should be considered whe n replacing tires :

62

Tire Warrant y

Tires are warranted by the tir e manufacturers as covered in the Ne w

Vehicle Warranty folder .

Tire Tractio n

A decrease in driving, cornering, an d braking traction occurs when water, snow , ice, gravel, or other material is on the road surface . Driving practices and vehicl e speed should be adjusted to the road conditions.

When driving on wet or slushy roads, i t is possible for a wedge of water to buil d up between the tire and road surface . This phenomenon, known as hydroplaning, may cause partial or complete loss of traction , which adversely affects vehicle control and stopping ability . To reduce the possibility of traction loss, the following precaution s should be observed :

1.

Slow down during rain-storms o r when roads are slushy .

2.

Slow down if road has standing water or puddles ,

3.

Replace tires when tread wea r indicators are visible .

4.

Keep tires properly inflated .

Snow Tire s

If the vehicle is expected to encounte r muddy or snowy driving conditions it i s recommended that front driving wheels b e equipped with mud and snow type tires.

If you equip your vehicle with mud an d snow tires, they should be of the same size, load range, and construction a s original equipment tires. It is recommended that vehicle speeds be limited to a maximum of 75 mph if mud and sno w tires are installed .

Tire Wear and Rotatio n

Uneven or abnormal tire wear is usuall y the result of incorrect inflation pressure , improper wheel alignment, wheels bein g out-of-balance, or poor driving habits .

Under-inflation, over-inflation, incorrect to e or camber and fast cornering produc e different types of abnormal wear which can be diagnosed by your dealer .

63

Tire Tread Wear Indicato r

To equalize wear it is recommended tha t the tires be rotated every 6,000 miles (o r sooner if irregular wear develops) as shown .

NOTE :

It is recommended that dis c brake pads be inspected for wear wheneve r tires are rotated .

The original equipment tires incorporat e built-in tread wear indicators to assist yo u in determining when your tires have worn to the point of needing replacement . These indicators appear as 1/2-inch wide band s when tire tread depth is 1/16-inch or less.

When the indicators appear in two or mor e adjacent grooves, tire replacement due t o tread wear is recommended .

Tighten wheel stud nuts as follows :

1.

Install all nuts loosely, the n finger-tighten only the nuts marked b y arrows .

2.

Tighten all nuts to specified torque i n sequence illustrated . Never use oil or grease on studs or nuts .

See IN CASE OF EMERGENCY sectio n for procedure used to change tire .

REAR WHEEL BEARING ADJUSTMEN T

Wheel Stud Tightening Sequenc e

Tightening Wheel Stud Nut s

When the vehicle is new or after wheel s have been replaced, it is the owner' s responsibility to check wheel stud nuts a t

5 00 miles and after every wheel remova l thereafter . Nuts should be tightened to 25 0 foot-pounds torque in sequence shown .

CAUTION

If any wheel experiences a single stu d failure caused by a loose-running wheel , all wheel studs should be replaced .

A loose-running wheel may caus e only one stud to break, but severa l more studs may become fatigued to the point of failure, but not actually breaking . Replacing only the broken stud and remounting whee l will then set the stage for a second and possible more serious failure . I f holes in the wheel have become elongated or enlarged, replace wheel .

A periodic rear wheel bearing repack i s required as indicated in Maintenanc e

Schedule folder . These bearings should b e cleaned and repacked with Lithium Soa p

Multi-Purpose Grease

Meeting G M

Specification 6031-M or equivalent .

The adjustment of the bearing must b e done with the wheel off the floor, an d rotating the wheel while tightening nut . At this time make the torque readings as follows :

1.

Tighten adjusting nut with a torque wrench . to 25-30 foot-pounds with whee l rotating to ensure that all parts are properly seated and threads are free .

2. Back off nut one-half turn . Re-tighte n nut finger-tight.

3.

If unable to install cotter pin a t finger-tight position, back off one slot , then secure with cotter pin .

4.

End play should be .001" to

.005" .

Also at this interval the rear suspension control arms should be lubricated . This i s accomplished at the fittings between the rear wheels .

64

FRONT SUSPENSIO N

The front suspension consists of control arms, stabilizer bar, shock absorbers and a right and left torsion bar . The front suspension components are designed t o provide satisfactory service, ride, and handling if not overloaded and adjusted t o specified vehicle front end ride height .

No maintenance other than lubrication i s normally required . Refer to lubricatio n information given earlier in this seciton fo r intervals and lubrication points .

The front of the torsion bar is attache d to the lower control arm . The rear of the torsion bar is mounted into an adjustabl e arm . The front ride height is controlled b y this adjustment .

The simplest way to adjust is to mov e arm slightly to achieve ride height an d drive unit a few blocks so as to overcom e delaying action .

1.

The wet tank (see illustration) should b e drained at 3 month or 3,000 mile intervals, o r more often if above normal air compresso r operation is encountered .

NOTE : Electro-Level components are located o n the left-side of the vehicle at the wheelhouse .

2.

The air compressor must periodicall y have the air filter washed with soap an d water solution or replaced . Filter should be serviced at intervals specified i n

Maintenance Schedule folder .

NOTE : Occasionally check air bellows t o see if they are caked with accumulate d mud deposits . If deposits are presen t remove them from air bellows .

NOTE :

Ride height is measured fro m top of elongated slot in frame rail t o ground level . Tire inflation should b e checked prior to making any ride heigh t adjustments .

The rear suspension can be manuall y adjusted for variations in load distribution .

Adjustment is made at the adjustment nu t on the height control valve arm .

Electro-Level Components

UNDERBODY MAINTENANC E

66

The effects of salt and other corrosiv e materials used for ice and snow remova l and dust control can result in accelerate d rusting and deterioration of underbod y components such as brake and fuel lines, frame, exhaust system, brackets, parkin g brake cables .

These corrosive effects, however, can be reduced by periodi c flushing of the underbody with plain water .

In geographic areas having a heavy concentration of such corrosive materials, it is recommended that the complete underbody be inspected and flushed at least once each year, preferably after a winter's exposure . Particular attentio n should be given to cleaning out underbod y members where dirt and other foreign materials may have collected .

If desired, your Motor Home dealer ca n perform this service for you . In addition , he can provide recommendations o n undercoating materials which will help protect your vehicle from corrosion . (Se e

IMPORTANT FACTS YOU SHOULD KNOW

ABOUT GASOLINE MILEAGE AND HOW TO 'IMPROVE I T

How you drive, where you drive, and whe n you drive all have an effect on how many mile s you can get from a gallon of gasoline . The careful attention you give your vehicle as far as maintenance and repairs are concerned will als o contribute importantly to fuel economy .

FUEL SELECTIO N

Use an unleaded gasolin e leaded gasoline . Additiona l

Requirements are given in

MAINTENANCE section .

or regular grade details on Fue l

SERVICE AND

"JACKRABBIT" START S

Gasoline can be conserved

(and engine and tire life prolonged) by avoiding unnecessaril y rapid acceleration away from lights and stop signs .

STOP-AND START DRIVIN G

Frequent stops and starts during a trip reall y cut down on your miles per gallon . Plan even your short trips to take advantage of throug h streets to avoid traffic lights . Pace your drivin g like the professional drivers to avoid unnecessary stops.

EXCESSIVE IDLIN G

An idling engine uses gasoline, too. If you'r e faced with more than a few minutes wait an d you're not in traffic, it may be better to "turn off " and start again later .

SUDDEN STOPS

Sudden stops themselves don't waste gasoline , but energy is wasted as heat in braking . Energy in the form of gasoline is also needed to accelerate back to driving speed.

LUBRICANT S

A properly lubricated vehicle means les s friction between moving parts. Consult thi s manual and the maintenance schedule for th e proper lubricants to use and the lubricatio n intervals.

AIR CLEANE R

Your vehicle receives its power from a mixture of gasoline and air . The air is taken into the system through the air cleaner so it's important to replace the air cleaner at required intervals. A dirty air cleaner reduces engine efficiency .

PROPERLY TUNED ENGIN E

Overall tuning (a check on timing, spar k plugs, emission control devices, etc .) can improve your vehicle's gas mileage. You just can't expect an "out-of-tune" engine to give you good gas mileage and cleaner air .

EXCESS WEIGH T

Fuel economy is related to the work the engine must do. The heavier the load, the more power it takes. Keep excess weight to a mini mum by removing any personal effects or luggage from the vehicle when they are not needed .

TIRE INFLATIO N

Underinflation not only causes needless wea r of the tires, but can also waste gasoline . It's a good idea to check tire pressures regularly .

WHEEL ALIGNMENT

"Toe in" or "toe out" has the effect of dragging your front tires sideways and causes prema ture tire wear . It takes power to carry this extr a load and that takes gas from your tanks .
