Brake reserve system warning (if equipped)
Illuminates to indicate normal
Hydromax booster reserve system
activation when the engine is OFF
and the service brake pedal is
applied, or when the ignition is in
the ON or START position.
This light may also illuminate momentarily if the engine is running and
the driver turns the steering wheel fully in one direction while braking.
If the light remains on while the engine is running, this indicates
inadequate hydraulic booster pressure or reserve pump system failure.
Stop the vehicle safely as soon as possible and seek service immediately.
Brake system warning
Momentarily illuminates when the
ignition is turned to the ON position
and the engine is off. If the brake
warning lamp does not illuminate at
this time seek service immediately.
If equipped with a hydraulic brake system and the warning lamp remains
illuminated after engine start up, this indicates a brake system
malfunction. Stop the vehicle safely as soon as possible and seek service
immediately.
If equipped with an air brake system, the warning light stays on until the
air pressure builds up to 414 kPa (60 psi). If the air pressure drops
below 414 kPa (60 psi) during operation, the remaining brake system is
still operational but the stopping distance will be greater.
Anti-lock brake system (ABS)
Momentarily illuminates when the
ignition is turned to the ON position
and the engine is off. If the light
remains on after the vehicle is
started, continues to flash or fails to
illuminate, have the system serviced immediately. With the ABS light on,
the anti-lock brake system is disabled and normal braking is still effective
unless the brake warning light also remains illuminated.

Trailer ABS brake system (if equipped)
Illuminates briefly when the engine
is powered-up and only when a PLC
trailer or a PLC diagnostic tool is
connected. If the light remains on
after the vehicle is started,
continues to flash or fails to illuminate, have the system serviced
immediately.
Parking brake warning (Hydraulic brakes only)
Momentarily illuminates when the
ignition is turned to the ON position
and the engine is off. Also
illuminates when the parking brake
is engaged. If the brake warning
lamp does not illuminate at these
times, seek service immediately.
Safety belt
Illuminates to remind you to fasten
your safety belts. For more
information, refer to theSeating
and safety restraintschapter.
Check trans (Allison automatic transmission)
The lamp will illuminate for several
seconds after the ignition is turned
to the ON position. Illumination of
this light indicates that a problem
has been detected and shifting may be restricted. Depending upon the
severity of the problem, the read-out digit on the shifter display may be
blank. Operation may continue in order to reach service assistance. The
ECU may not respond to shift selector requests, since operating
limitations are being placed on the transmission, i.e. upshifts and
downshifts may be restricted. Direction changes will not occur.
Refer to the Transmission Operator’s Manual for more information.

Air pressure gauge and warning buzzer (if equipped)
Indicates the amount of air pressure
in the brake system (green=primary,
red=secondary) in pounds per
square inch. When the pressure is
too low for normal brake operation
(less than 414 kPa [60 psi]) and the
ignition is turned to ON:
•a warning buzzer sounds
•the warning light illuminates
All vehicles have a dual-pointer air
pressure gauge to indicate the pressure in both brake circuits.
Vehicles equipped with rear air suspension also have a dual-pointer air
pressure gauge.
Do not drive the vehicle when the low air pressure buzzer is
sounding or the warning light is lit. These warnings indicate
there is not enough air pressure for the brake or suspension system to
operate properly.
Battery voltage gauge
Indicates battery voltage. If the
pointer moves and stays outside the
normal operating range, have the
vehicle’s electrical system checked
as soon as possible.

The BeltMinder feature can be deactivated/activated by performing the
following procedure:
Before following the procedure, make sure that:
•The parking brake is set.
•The gearshift is in P (Park) (automatic transmission) or the neutral
position (manual transmission).
•The ignition switch is in the OFF position.
•All vehicle doors are closed.
•The driver’s safety belt is unbuckled.
•The parklamps/headlamps are in OFF position (If vehicle is equipped
with Autolamps, this will not affect the procedure).
To reduce the risk of injury, do not deactivate/activate the Belt
Minder feature while driving the vehicle.
BeltMinder activation and deactivation procedure
1. Turn the ignition switch to the RUN (or ON) position. (DO NOT
START THE ENGINE.)
2. Wait until the safety belt warning light turns off. (Approximately 1–2
minutes.)
•Steps 3–5 must be completed within 60 seconds or the procedure will
have to be repeated.
3. Buckle then unbuckle the safety belt three times, ending with the
safety belt unbuckled. This can be done before or during BeltMinder
warning activation.
4. Turn on the parklamps/headlamps, turn off the parklamps/headlamps.
5. Buckle then unbuckle the safety belt three times, ending with the
safety belt unbuckled.
•After step 5 the safety belt warning light will be turned on for three
seconds.
6. Within seven seconds of the safety belt warning light turning off,
buckle then unbuckle the safety belt.
•This will disable BeltMinder if it is currently enabled, or enable
BeltMinder if it is currently disabled.
7. Confirmation of disabling BeltMinder is provided by the safety belt

STARTING PROCEDURES
Operating precautions
•Always shift to a lower gear at high altitudes to prevent engine
smoking.
•Avoid extended and unnecessary idling.
Diesel engine vapors are combustible. Do not operate the engine
in an enclosed area. These vapors can be sucked through the air
intake system and cause engine acceleration and overspeeding, which
may result in bodily injury and extensive property damage. The
equipment owner and operator are responsible for safe operation in a
hostile environment.
Starting the engine
1. Ensure headlamps and all accessories are turned off, the parking
brake is applied and the transmission is in the neutral position (or P
[Park] for Allison 2400 transmissions).
If your vehicle is equipped with an
air intake heater, the heater will
activate in cooler weather. If the
Wait to startlight illuminates,do
notcrank the engine until the light
goes off.
If equipped with an air intake heater, DO NOT use ether or any
other starting fluids. The use of starting fluids (ether) in an
engine equipped with an air intake heater could cause an explosion
and result in vehicle damage, property damage and/or personal injury.
2. Do not depress the accelerator during starting the engine.
3. Start the engine.
If the engine does not start after 30 seconds of cranking, allow two
minutes for the starter to cool before trying again. Excessive cranking
may damage the starter.
After the engine starts:

The sound of the pump operating may be heard by the driver, but this is
a normal characteristic of the system.
The reserve system provides reduced braking power, so the vehicle
should be operated under these conditions with caution, and only to seek
service repair and remove the vehicle from the roadway.
For Hydromax under normal operating conditions noise of the fluid
flowing through the booster may be heard whenever the brake is applied.
This condition is normal. Vehicle service is not required.
If braking performance or pedal response becomes very poor, even when
the pedal is strongly applied, this may indicate the presence of air in the
hydraulic system or fluid leakage. Stop the vehicle safely as soon as
possible and seek service immediately.
If the red BRAKE warning lamp in
the instrument cluster remains
illuminated after engine start up,
this indicates a system failure in the
master cylinder of the brake system. Stop the vehicle safely as soon as
possible and seek service immediately.
If the yellow BRAKE RESERVE
(E-motor) warning light remains on
while the engine is running, this
indicates inadequate hydraulic
booster pressure or reserve pump
system failure. Stop the vehicle safely as soon as possible and seek
service immediately.
Four-wheel anti-lock brake system (ABS)
A noise from the hydraulic pump motor and pulsation in the pedal may
be observed during ABS braking events. Pedal pulsation coupled with
noise while braking under panic conditions or on loose gravel, bumps,
wet or snowy roads is normal and indicates proper functioning of the
vehicle’s anti-lock brake system. If the vehicle has continuous vibration
or shudder in the steering wheel while braking, the vehicle should be
inspected by a qualified service technician.
