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.

To set a speed
7.3L Power Stroke engine
•Press SET ACCEL. For speed
control to operate, the speed
control must be ON and the
vehicle speed must be greater
than 48 km/h (30 mph).
Do not use the speed control in heavy traffic or on roads that
are winding, slippery, or unpaved.
Caterpillar/Cummins engines
Press SET +. If the vehicles is
moving, this will set the vehicle
speed. If the vehicle is stationary,
this will set the vehicle idle RPM.
If you drive up or down a steep hill, your vehicle speed may vary
momentarily slower or faster than the set speed. This is normal.
Speed control cannot reduce the vehicle speed if it increases above the
set speed on a downhill. If your vehicle speed is faster than the set
speed while driving on a downhill, you may want to shift to the next
lower gear or apply the brakes to reduce your vehicle speed.
If the vehicle speed falls below 48 km/h (30 mph) or engine RPM falls
below 1 000 RPM, your speed control will disengage. This is normal.
Pressing RESUME - will re-engage it.
Do not use the speed control in heavy traffic or on roads that
are winding, slippery, or unpaved.
