Brake system warning light:To
confirm the brake system warning
light is functional, this light will
momentarily illuminate when the
ignition is turned to the on position when the engine is not running. If
the brake system warning light does not illuminate at this time, seek
service immediately from your dealership. Illumination after starting the
vehicle indicates a brake system fault and should be inspected
immediately by your dealership.
Note:The Brake System Warning light may be accompanied by a
warning buzzer or chime.
If equipped with an air brake system,the warning light stays on until
the air pressure builds up to 60 psi (414 kPa). If the air pressure drops
below 60 psi (414 kPa) during operation, the remaining brake system is
still operational but the stopping distance will be greater.
WARNING:Driving a vehicle with the brake system warning
light on is dangerous. A significant decrease in braking
performance may occur. It will take you longer to stop the vehicle.
Have the vehicle checked by your dealer immediately. Driving
extended distances with the parking brake engaged can cause brake
failure and the risk of personal injury.
Wait to start:Indicates the air
intake heater is in operation and
special starting procedures are
required. Refer toStartingin the
Drivingchapter.
WARNING: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 result in
damage and/or personal injury.

Water in fuel:During refueling, it
is possible for water-contaminated
diesel fuel to be pumped into your
tank. Your vehicle fuel system is
equipped with a fuel filter/water
separator to remove water from the fuel. The WATER IN FUEL light will
illuminate when the fuel filter/water separator has a significant quantity
of water in it.
If the light illuminates when the engine is running, stop the vehicle as
soon as safely possible, shut off the engine, then drain the fuel
filter/water separator. Refer to your engine operator’s manual for the
drain procedure. Allowing water to stay in the system could result in
extensive damage to, or failure of, the fuel injection system.
WARNING:Do not drain water separator while engine is
running. Fuel may ignite if separator is drained while engine is
running or vehicle is moving.
Traction control (if equipped):
Illuminates and flashes slowly if the
Off Road or Mud/Snow mode is
selected and flashes rapidly during a
traction control event.
Differential lock:Illuminates when
the main differential is locked
(engaged).
Parking brake warning:
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 parking brake
warning lamp does not illuminate at
these times, seek service immediately.
Vehicles equipped with the Power Park Parking Brake option:If
after setting the parking brake on your vehicle the park brake warning
lamp begins to blink, this may indicate a failure in the parking brake
system. Seek service from your dealer immediately.

Trailer Anti-lock Brake System
(ABS):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.
Anti-lock Brake System (ABS):If
the ABS light stays illuminated or
continues to flash, a malfunction has
been detected, have the system
serviced immediately. Normal
braking is still functional unless the brake warning light also is
illuminated.
Check transmission (Allison
automatic transmission only):
The lamp will illuminate for several
seconds after the ignition is turned
to the on position. Illumination of this light while driving 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 your transmission operator’s manual for more information.
Safety belt:Reminds you to fasten
your safety belt.
Range inhibit:Illuminates when
the transmission is not engaged in
the selected gear. The warning light
will go off when the gearshift lever
is adjusted in to the appropriate gear.
Refer to your transmission operator’s manual for more information.

Air pressure gauge:All vehicles
equipped with air brakes have a
dual-pointer air gauge to indicate
the pressure in each brake circuit.
The green pointer indicates the air
pressure in the primary system and
the red pointer indicates the air
pressure in the secondary system.
When the pressure is too low for
normal brake operation (less than
60 psi [414 kPa]) and the ignition is
on:
•a warning buzzer will sound and
•a warning light will illuminate in the instrument cluster
WARNING: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.
Vehicles equipped with hydraulic brakes and an air compressor have a
single-pointer air gauge.
Note:This system doesnothave a low air pressure warning buzzer or a
low air pressure warning light.
