Engine starting (parking brake applied)
Ammeter/Voltmeter:Check the gauge to see if the alternator is
charging.
Steering linkage
free play:Check for excessive free play in the steering
linkages. The steering wheel should have less
than two inches (five cm) of free play at rim
of steering wheel.
Hydraulic brake
check:When the engine is off, the pump will turn on
if the brake pedal is applied, or if the ignition
is turned to the ON position.
Air brake check:Check the air brakes in the following manner
(Chock the wheels, if necessary. Push in the
parking brake and on tractors, also push in the
tractor parking brake knob):
1. Check the air compressor or governor
cut-out pressure (approximately 120 psi [827
kPa]).
2. Cut-off the engine and turn the key back to
ON, without starting the engine.
3. Without the brake pedal applied, note the
air pressure drop for one minute. It should be
less than 2 psi (14 kPa) for single vehicle and
3 psi (21 kPa) for combination vehicles.
4. Depress and hold the brake pedal with 90
psi (621 kPa) or more and make sure there is
no more than a 3 psi (21 kPa) per minute
leak. For combination vehicles, no more than 4
psi (28 kPa) per minute.
5. Pump the brake pedal to deplete the system
air pressure. The warning light and chime
should activate 57 psi (393 kPa).
6. Pump the brake pedal and make sure the
parking brake and trailer parking brake knobs
pop out at 20 psi (138 kPa) or higher.

Stop engine:This light is used in
conjunction with the electronic
engine control.
Refer to the Engine Operator’s Manual for specific information regarding
this feature.
If the engine shuts down, it can be restarted and operated for 30
seconds at a time or until the problem is corrected. Refer toEngine
shutdown systemin theDrivingchapter.
Drivers of electronically controlled engines should know the
extent of warning engine shutdown system before operating the
vehicle. This information can be obtained from your dealer.
Brake reserve system warning:
Illuminates to indicate normal
Hydromax booster reserve system
activation when the engine is OFF
and the service brake pedal is
applied.
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 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 pressure differential in the master cylinder and the
brake system should be inspected immediately by your dealership.
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.
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.

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 brake warning
lamp does not illuminate at these
times, seek service immediately.
Vehicles equipped with the Power Park (air-operated 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 ABS brake system:
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: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 trans (Allison automatic
transmission only):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 theTransmission Operator’s Manualfor 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 theTransmission Operator’s Manualfor more information.
Charging system:Illuminates when
the battery is not charging properly.
Turn signal:Illuminates when the
left or right turn signal or the
hazard lights are turned on. If the
indicators stay on or flash faster, check for a burned out bulb.
High beams:Illuminates when the
high beam headlamps are turned on.
Safety belt warning chime:Sounds when the key is in the ignition and
the driver’s safety belt is not fastened.

GAUGES
Some of the gauges shown are optional based on vehicle equipment; your
vehicle may not have some of the gauges shown in this section.
Speedometer:Indicates the
current vehicle speed.
Tachometer:Indicates the engine
speed in revolutions per minute.
Driving with your tachometer
pointer continuously at the top of
the scale may damage the engine.
Odometer:Registers the total miles
(kilometers) of the vehicle.

Trip odometer:Registers the miles
(kilometers) of individual journeys.
To reset, depress the control.
Fuel gauge:Indicates
approximately how much fuel is left
in the fuel tank (when the ignition
is in the on position). If your vehicle
is equipped with dual fuel tanks, the
engine will draw fuel from the
passenger-side fuel tank only. With
dual fuel tanks, the vehicle will be
equipped with a fuel transfer pump system that will draw fuel from the
driver-side fuel tank and send fuel to the passenger-side fuel tank. The
passenger-side fuel tank must have fuel in it at all times otherwise the
vehicle may stall and may be difficult to re-start. The fuel gauge reads
the fuel level only from the passenger-side fuel tank.
Engine coolant temperature
gauge:Indicates engine coolant
temperature. At normal operating
temperature, the needle will be in
the normal range (between “H” and
“C”).If it enters the red section,
the engine is overheating. Stop
the vehicle as soon as safely
possible, switch off the engine
and let the engine cool.
Never remove the coolant reservoir cap while the engine is
running or hot.

Engine oil pressure gauge:
Indicates engine oil pressure. The needle should stay in the normal
operating range (as indicated by the arrows). If the needle falls below
the normal range, stop the vehicle, turn off the engine and check the
engine oil level. Add oil if needed. If the oil level is correct, have your
vehicle checked at your dealership or by a qualified technician.
Battery voltage gauge:Indicates
the battery voltage when the
ignition is in the ON position. If the
pointer moves and stays outside the
normal operating range (as
indicated by arrows), have the
vehicle’s electrical system checked
as soon as possible.
Transmission temperature gauge
(if equipped, automatic
transmission only):
Indicates the temperature of the
transmission fluid. The normal
temperature range is 150°–230°F
(65°–110°C). Readings of
230°–250°F (110°–121°C) are
satisfactory for intermittent
operation and are not cause for
alarm. Operation above 250°F
(121°C) can cause the fluid to break down and will result in component
damage.

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
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.
