Seat Belt Inspection
Every 30 days, check the belt, buckle, latch plate,
retractor and guide loops for proper operation.
Check for loose or damaged parts. Keep sharp
edges and sharp objects away from belts and other
parts of the restraint system.
Exterior Rear-view Mirrors
Exterior mirrors have separate upper and lower
segments. The convex upper portion is for wideangle view.
Adjust the exterior mirrors so that you can see the
side of the coach in part of the mirror. This helps
determine the relationship of the coach to objects
seen in the mirror.

Bendix Wingman System (Optional)
Figure 21.
The Driver is always responsible for the
control and the safe operation of the vehicle
at all times. The Bendix Wingman Advanced
(or ACB) system does not replace the need
for a skilled, alert professional driver,
reacting appropriately and in a timely
manner, and using safe driving practices.
Any audible and/or visual alert by the system
means that your vehicle is too close to the
vehicle ahead, immediately act to potentially
avoid, or lessen the severity of, a collision.
Improper use of the Bendix Wingman
Advanced ( or ACB ) system can result in a
collision causing property damage, serious
injuries, or death.
The Wingman Advanced ( or ACB ) system is
automatically ready when the cruise control
is set. However, cruise control must be used
only in the same conditions that are normally
recommended for ordinary cruise control. As
noted below, there are certain situations
when cruise control should NOT be used. Do
not use cruise control in the following
conditions or situations:
•
Inclement weather (rain, snow, fog,
ice or other severe weather
conditions)
•
Dense Traffic
•
Sharp curves and winding roads
•
Entrance or exit ramps
•
Downhill grades
•
Construction zones
•
Smaller forward vehicles - Smaller
vehicles, such as motorcycles, may
be difficult for the radar to identify. It
is the driver’s responsibility to be
aware of these types of vehicles and
to slow down if necessary.
Any vehicle trouble code that disables
vehicle cruise control will also cause a
diagnostic trouble code in Wingman
Advanced ( or ACB ). The Wingman system
will not operate until the DTC is cleared.
Active Cruise with Braking (ACB)
The Wingman system is engaged by turning cruise
control ON and setting the vehicle speed. The system
helps maintain a set distance between the operated
vehicle and a detected vehicle ahead. To disengage
the system, turn the cruise control OFF or press the
brake pedal.
22
Collision Mitigation (Advanced)
Audible and visual alerts are provided to the
operator through a Driver Interface Unit (DIU). All the
alerts are always active regardless whether cruise
control is engaged or not. Any alert means your vehicle
is too close to another vehicle or object. These alerts
will change as the distance between the two vehicles
decreases alerting the operator of the impending
hazard. As the distance closes, the system will
automatically intervene and slow the vehicle.
June 2016
Following Distance Alert (FDA)
The radar system only senses metallic
objects. Non-metallic or limited metallic
objects such as people, animals, RVs,
motorcycles, horse drawn buggies, logging
vehicles, or cross- traffic will not trigger the
system.
Due to inherent limitations of radar
technology, the collision mitigation
technology on rare occasions may not detect
moving vehicles or stationary objects in your
vehicle’s lane of travel.
Road curvature may impact the radar’s ability
to track vehicles ahead in the same lane.
Operator alerts, warnings, or brake
interventions may not occur. In addition, the
system may react to moving vehicles not in
your vehicle’s lane of travel. Operator alerts,
warnings, or brake interventions may occur.
A FDA is generated through the DIU using vehicle
speed, forward vehicle speed, distance and driving
scenarios.
These alerts indicate that the time between
your vehicle and the detected forward vehicle
ahead is less than one and a half ( 1.5 )
seconds and decreasing. Once the audible
alert is heard, the driver should increase the
distance between their vehicle and the vehicle
ahead until the audible alert stops.
Single, Yellow Illuminated LED
The forward vehicle is within a 1.5 seconds range
and traveling at the same speed or slower.
The screen will visually show the distance between
the vehicles, closing.
Two, Yellow Illuminated LEDs
The forward vehicle is much too close and traveling
at the same speed or slower. The screen will visually
show the vehicles slightly closer to each other.
All Three, Yellow Illuminated LEDs
This is the closest and most urgent Following
Distance Alert. The forward vehicle is in this zone and
traveling at the same speed or slower. The screen will
visually show the distance between the vehicles as
very close.
All Three, Red Illuminated LEDs

3. OK Button
This alert is the most severe warning. A loud solid
tone is generated, and the screen will flash. The
system will automatically slow down the vehicle. The
operator must apply additional braking to maintain a
safe distance from the vehicle ahead. If a collision is
likely to occur, and the collision mitigation feature
activates the brakes, the tone of the alert will change
and the screen will flash between two displays.

This alert indicates that a collision with the
detected forward vehicle is likely and the
driver must immediately act to potentially
avoid, or lessen the severity of a collision.
23
Two Yellow Illuminated LEDs
The radar detects a sizable, non-moving, metallic
object in the vehicle's path of travel.
Brake Overuse Alert
All three types of alerts ( FDA, IA, and SOA )
will continue to be provided during the brake
overuse alert.
False Alerts
This alert is provided when the system is
intervening and using the brakes excessively.
Brake overuse can lead to overheating and a
potential loss of braking performance (brake
fade).
Using cruise control on downhill runs will
cause this alert. Do not use cruise control on
downhill grades.
In certain unusual traffic or roadway conditions,
Wingman Advanced (or ACB) may issue a false alert.
While eliminating all false alerts is not possible, if false
alerts occur too frequently (more than twice a day), this
may indicate sensor misalignment. Service the system
at the earliest opportunity.
Front Bumper Radar Sensor
The sensor relaying information to the DIU is
located on the front bumper of the coach.
Blinking Blue LEDs
When brake overuse is detected, a text message
and audible alert/alarm is generated and the DIU blue
LED will illuminate. The operator has 15 seconds to
take action (turn cruise control OFF or apply the
brakes).
Solid Blue LEDs
If the operator doesn't take action within 15
seconds, the system will shut off and a DTC
(Diagnostic Trouble Code) will be generated. All
intervention features of the system will remain off until
the next ignition cycle. If the operator does intervene
within the 15 seconds, the system will remain
unavailable for 20 minutes. After 20 minutes the
displayed ACB Braking Overuse message will
disappear and the blue LED will turn off.

ELECTRIC HORN
Press the horn bar on the steering wheel center
hub to activate the electric horn.
ACCELERATOR PEDAL
The accelerator pedal is to the right of the service
brake pedal.
SERVICE BRAKES
DO NOT pump the brake pedal.This defeats
the purpose of the ABS.
The ABS telltale on the LH telltale cluster is used
for blink code diagnostics and lets the driver know the
status of the system. The telltale lights briefly at
ignition. If it lights at any other time, the system
requires service. Full regular braking remains, and
partial ABS may be present.
Do not apply the parking brakes until the
coach has come to a complete stop.
The coach has air-operated service brakes that are
applied with the foot pedal to the left of the accelerator
pedal.
If an ABS malfunction is indicated by the ABS
telltale lamp, the driver must safely stop the
coach and safely check all six (6) wheel ends
for an overheat condition.
Stop lamps on the rear of the coach light when the
brake pedal is pressed. The STOP LAMPS telltale on
the RH telltale cluster lights.
If an overheat condition exists, the coach
must NOT be driven until inspected by a
qualified technician.
ANTI-LOCK BRAKES (ABS)
The anti-lock brake system (ABS) minimizes brake
lock-up at each wheel.
In the event of an ABS malfunction, the
braking system will default to a normal
braking system. Exercise caution to avoid
potential wheel-lock conditions.

5 - OPERATING FEATURES
ENTRANCE DOOR
The entrance door is controlled by a switch on the
RH switch panel on the instrument panel, or by an
exterior switch located rearward of the door
( Figure 30 ).
To lower the coach, press and hold the KNEEL half
of the switch in the RH switch panel. While the coach is
lowering, the KNEEL telltale and exterior kneel lamps
flash, and interior and exterior (optional) buzzers
sound. When the coach reaches kneel height, the
telltale remains lit, but the exterior lamp and buzzer(s)
go off (Figure 30.).
To return to normal ride height, press and release
the RECOVER half of the switch.
If the KNEEL switch is released before the coach is
fully knelled, the coach stops lowering. To resume
kneeling, press and hold RECOVER to return to normal
ride height, then press and hold KNEEL to reactivate
kneeling.
Figure 30. Exterior Entrance Door Switch
The DOOR OPEN telltale turns ON when the door
is open.
To operate, hold the switch until the door is fully
opened or closed. The door may be stopped anywhere
in its travel by releasing the switch. The door catch will
engage when the door is in the fully closed position
only, with the ignition ON.
KNEELING
The coach has a kneeling feature that allows the
operator to lower the front of the coach five (5) inches
(127 mm) for ease of boarding.
To activate the kneeling feature, the park brake
must be set, the transmission must be in Neutral and
the entrance door must be closed.
The coach automatically returns to normal
height if the park brake is released or the
transmission is shifted out of Neutral.
REAR RISE
The coach may be equipped with the rear rise
option, which prevents rear bumper scuffing in offhighway situations by raising the rear bumper
approximately three (3) inches (76 mm) above normal
ride height.
The Rear Rise switch is located on the RH switch
panel. When the coach is traveling under 20 mph
(30 kph) and the RAISE half of the switch is pressed,
the rear of the coach rises, the HIGH RIDE telltale
lights and a buzzer sounds.
Pressing the Normal Ride / Recover switch or
traveling above 20 mph (30 kph) returns the coach to
normal ride height.
To avoid personal injury and property
damage, ensure that nothing is under the
coach when kneeling.
Do not operate the coach in the high position
for extended periods. Lower the rear rise
system before any suspension maintenance
or inspection.
June 2016
29
TAG AXLE UNLOAD, ELECTRICAL
( OPTIONAL )
The electrical tag axle unloading feature allows the
operator to partially unload the tag axle using a dashmounted switch. When the coach cannot get traction,
this transfers weight to the drive axle. The operator
should refill the tag as soon as the coach has regained
traction. It is unsafe to drive the coach with the tag axle
air springs unloaded.
Only the tag axle unloading feature in low
traction situations.
Do not use it for normal driving. Reduce
coach speed when the tag axle air springs are
unloaded.
To unload, press the TAG AXLE switch located on
the LH switch panel. The TAG UNLOAD telltale will
light and a buzzer will sound.
To re-load, press the TAG AXLE switch again or
drive above 17 mph.
The MUD/SNOW switch is included with ATC. On
extra soft surfaces, such as mud, deep snow or gravel,
this feature increases traction by slightly increasing
wheel spin. When MUD/SNOW is active, the LOW
TRACTION telltale blinks continuously.
ELECTRONIC STABILITY CONTROL
Coaches are equipped with a stability control
system that features Electronic Stability Control (ESC)
combined with Roll Stability Control (RSC). ESC is a
computerized technology that improves the safety of a
vehicle's handling by detecting and potentially
preventing skids by automatically applying brakes to
help steer the vehicle where the driver wants to go.
ESC is automatic in that these systems become
active when the system Electronic Control Unit (ECU)
senses conditions that could produce imminent roll or
directional instabilities. Rapid lane changes or
cornering at excessive speed on dry or slippery
surfaces can create the potential for spin-out or drift
out, often before the operator is aware. The ESC
system uses a lateral accelerometer, a steer angle
sensor in the steering column and a yaw rate sensor to
enhance the operator's control in these conditions.
Applying the service brake prevents MDSS from
self-leveling the coach when the tag axle is unloaded.
IN-STATION LIGHTING/BATTERY
CHARGER ( OPTIONAL )
An optional 110V AC receptacle in the battery
compartment provides for in-station lighting and battery
charging.
AUTOMATIC TRACTION CONTROL ( ATC )
This system improves traction when the coach is
on slippery surfaces by reducing drive wheel spin. If
one drive wheel starts to spin, ATC applies the brake to
transfer engine torque to the wheel with better traction.
If all drive wheels spin, ATC reduces engine torque to
improve traction.
The telltale comes on when the drive wheels spin
during acceleration. It goes out when the drive wheels
stop spinning. ATC is always active; the operator does
not have to select it.
30
The stability control system is designed to
assist the operator, not to replace the
operator.
The operator will notice a difference in the
coach when the ESC system becomes active,
but should continue to drive as normal and
provide any additional needed corrections.
In an ESC event, the operator may first sense
a decrease in engine power as the system
ECU overrides the accelerator pedal, and may
then sense additional deceleration from an
engine brake application and service brake
applications on the steer axle brakes or all
axle brakes, depending on whether the
conditions suggest the possibility of a
directional control or a rollover event.

Positioning The Wheelchair
Since the QRT Retractable System consists of
self-locking and self-tensioning retractors which retract
and lock automatically, the driver can position the
wheelchair anywhere within the clear floor space which
will allow for convenient access to securement points
on the wheelchair.
Securing The Passenger
The self-locking and self-tensioning features of the
QRT enables the driver to secure the wheelchair
beginning with either the front or rear retractors or if
standing on the lift with the wall side front and rear
retractors if this is more convenient.
Explain to the passenger what you are doing
to make them feel comfortable with the
process.
Figure 47. QRT Instruction placard
mounted on cabin access door.
1. Ensure a straight line from anchorage to
wheelchair attachment.
2. Select the appropriate attachment points on the
wheelchair. Look for frame members that are
welded or securely bolted to each other.
DO NOT use removable armrests, footrests,
wheels of the crisscross supports on folding
wheelchairs.
3. The rear attachment points should be a solid
frame member as near as possible to where the
seat and the back meet. The front attachment
points should be a solid frame member, which
will create an angle between 30 and 45 degrees
to the retractor.
4. Attach the “J” hooks on all four retractor belts to
solid frame members.
5. Ensure that the belts are properly tensioned.
DO NOT allow the webbing to be twisted

[140F - 220F (60C - 104C)], park the vehicle on a level
surface, select Neutral and allow the engine to idle
(500-800 rpm).
NOTE: Coach should be stationary for approx. two
minutes to allow the fluid to settle. NO fast idle
during electronic fluid check.
2. Simultaneously press the UP and DOWN arrow
buttons once. There may be a short delay while the
fluid and temperature stabilizes.
3. The fluid level will display:
If correct, OL-OK.
If low, OL-LO-# (number of quarts of
transmission fluid required).
If high, OL-HI-# (number of quarts
overfilled).
4. Confirm with a manual fluid level check.
Low and High fluid levels cause overheating
and irregular shift patterns. If not corrected,
transmission damage can occur.
June 2016
Manual Cold Fluid Level Check
Do a cold check to ensure that the transmission
has enough fluid for safe operation until a hot check
can be done. Check the reading at least twice.
1. Park the coach on a level surface and apply the
parking brake.
2. Run the engine for at least 1 minute.
3. Apply the service brakes, shift the transmission
to drive (D) and operate the engine at 1000 to
1500 rpm for 30 seconds. Shift to reverse (R) to
clear air from the hydraulic system. Shift to
neutral (N) and idle the engine at 500-800 rpm.
4. With the engine running, remove the dipstick
from the tube and wipe it clean.
5. Insert the dipstick into the tube and remove it.
Check the level reading.
6. Repeat to verify the reading.
7. If the fluid level is within the COLD RUN band,
the transmission may be operated until the fluid
is hot enough to perform a hot check. As
required, add fluid to bring the level to the
middle of the band.
8. Perform a hot check as soon as the coach
reaches normal operating temperature [140F 220F (60C - 104C)].
Dipstick checks may not agree exactly with
sensor checks, because the oil level sensor
compensates for fluid temperatures.
