Tire Care
Maintaining the proper tire inflation pressure is the most important thing you can do to maximize the life of
your tires. An under-inflated tire can build up excessive heat that may go beyond the prescribed limits of
endurance of the rubber and the radial cords. Over-inflation will reduce the tire’s footprint on the road,
reducing traction, braking capacity, and the handling of your vehicle. An over-inflated tire will also cause a harsh
ride, uneven tire wear, and will be more susceptible to impact damage.
Keep in mind that the pressure rating on the side wall of your tire is the maximum pressure for that tire. This is
not necessarily the correct pressure for the tires when installed on your vehicle. Maintaining the correct tire
pressure for your vehicle’s loaded weight is extremely important and must be a part of regular vehicle maintenance.

To determine the correct air pressure for your tires, load your motor home as you would normally travel,
including water and fuel. Go to a truck scale as found at most major truck stops and weigh each wheel
position independently, with driver and passenger(s) in the vehicle as described in the Michelin Recreational
Vehicle Tire Guide (MWL43146 Rev. 6/07) to determine the correct air pressure for the weight on each
wheel position. Then use the charts in the guide and adjust the pressure accordingly when the tires are cool or
have not been driven for more than one mile. You may call 1-800-847-3435 for a copy of the Michelin
Recreational Vehicle Tire Guide .
NOTE: Never reduce the air pressure in a hot tire.
REMEMBER: For control of your RV, it is critical that the tire pressure be the same on both sides of the axle.

Brake System
Figure 2-1: Rear Brakes
•
Front brakes are air applied drum
-
•
•
Two large 15 x 4” drum brakes
Rear brakes (Figure 2-1) double as parking brake
-
Park brakes are spring applied
-
Two large 15 x 8.625” drum brakes
-
Park brake remains applied even if air pressure is lost
If air pressure is lost
-
•
A buzzer and warning lamp will alert you
Chassis is equipped with automatic slack adjusters (Figure 2-2)
-
No brake adjustment required
Figure 2-2: Automatic Slack Adjuster
The rear brakes on the PowerGlide chassis are also used as the parking brakes. This provides you the holding
power of two large drum brakes to prevent your coach from rolling, even when fully loaded on a 20% grade.
A decrease in air pressure will not cause an immediate loss of brakes. If a leak develops in the air system while
driving (at approximately 60 to 65 PSI), you will be alerted via a light on the instrument panel and an audible
alarm. As you apply the brakes, the air supply holding the park brakes in the released position will gradually be

S Y S T E M
depleted. When fully depleted (approximately 40 PSI to 45 PSI), the rear brakes will set. This allows you
sufficient time to pull over to the side of the road.
NOTE: The rear brakes have dual chambers – one for the service brakes and one for the park brake. The
service brakes are air applied and spring released. The park brake is spring applied and air released.
The brake system is equipped with automatic slack adjusters that avoid the need to manually adjust your brakes.
Each time you step on the brake pedal, if adjustment is needed, the adjusters will take up the slack.
Compressed Air System
Tank Drains
Figure 2-3: Tank Drains
The compressed air system is comprised of two air storage tanks. The primary tank stores and supplies air for
the rear brakes, the secondary tank stores and supplies air for the front brakes.
When air is compressed it becomes hot. As it cools, condensed moisture forms in the system. The air system is
equipped with an air dryer to remove most of this moisture. The dryer has an automatic moisture ejector that
releases the trapped moisture back into the atmosphere. However, some moisture will form in the system
beyond the dryer, and make its way into the storage tanks. As moisture collects in the primary and secondary
tanks, it displaces the area needed for air storage, thus requiring that the tanks be drained periodically.
2-3
B R A K E
S Y S T E M
The air system is equipped with air tank drains conveniently located in the left rear storage compartment
(Figure 2-3). There is one drain for the primary tank and one for the secondary tank. These drains should be
opened daily for a few seconds to remove any moisture trapped in the tanks.
Air Dryer
Figure 2-4: Haldex Dryest Air Dryer
The Tiffin PowerGlide chassis air brake system features a Haldex Dryest air dryer (Figure 2-4), which removes
the condensed moisture from compressed air. The air dryer is equipped with a desiccant cartridge that needs to
be changed every 36 months. The dryer is located on the passenger side, in the forward rear box next to the
A/C condenser (behind the rear axle).
Warning
Air tanks should be bled of all pressure any time you perform work on the air system.

Pre-Trip Inspection
•

•
Check fluid levels & add as necessary
Check tire inflation pressure
Look for fluid leaks
Before starting your motor home daily, a few things must be checked. By doing so, you ensure that a safe trip is
in order and lessen your chances of experiencing difficulties while on the road.
•
Check the tires for proper inflation pressure and any damage. Also check the inner duals. Refer to the
air pressure charts in this manual for proper inflation pressures.
•
Look for fluid leaks under the motor home. This can prevent any serious problems from occurring
later.
•
Check the coolant level in the reservoir and add a 50/50 mix of coolant and water if necessary. This
reservoir can be found on the rear of your vehicle.
•
Check ELC (Extended Life Coolant Extender) and freeze point every 30 months or 150,000 miles.
Recharge as required.
Caution
If the water temperature in your engine is greater than 120 degrees, do not remove the
radiator cap! You could be severely burned.

After you have completed your inspection, you may now start your engine. Turn the key to the run position
and wait for the wait to start light (in some cases it may read “Inlet heater”) to turn off. You may now start the
engine. Never use ether or any other starting fluids to start the electronic engine. The inlet heater can
ignite the fumes and cause an explosion in the air inlet system. Once you have started the engine,
monitor your gauges carefully. Make sure that the oil pressure rises within 15 seconds. If it does not, shut down
the engine and call a repair facility to determine the cause.

DPS Instrument Cluster Operation
Sleep Mode
DPS is in sleep mode when battery voltage input is high, ignition key is off and wake-up
inputs are not active. In this state DPS electronics are at minimum power consumption.
The system exits sleep mode when one of the following wake-up inputs becomes active.
•
•
Ignition key input
Right and Left signal light inputs (hazard lights)
Limited mode
In limited mode the ignition key is off and the DPS offers functionality for:
•
HAZARD WARNING LIGHTS
The right turn signal input is a wake-up input. When active the DPS will wake-up
and check the status of the left signal input, and if active, will turn ON the right and
left turn signal indicators.
o
Run mode
The DPS enters Run mode when the ignition key input is switched to high (active). This
event initiates the self test routine, which takes approximately 5 seconds to complete.
When the ignition input goes inactive, the DPS will drive all gauge pointers to zero except
the fuel gauge.
Self Test
GAUGES
Gauge pointers sweep to full scale. The pointers will return to zero position and then to
operational position.
LCD
The LCD will turn all segments on for one second, off for one second and then display the
Tiffin Motorhomes logo until the start-up routine is complete
WARNING LIGHTS
The warning lights will turn on and then go to operational state at the end of the self test.
AUDIBLE ALARM
A steady alarm tone will be generated and then go to operational state at the end of the
self test.
