Driver/Fuel area
Fuel tank:Make sure the fuel tank and caps are secure.
Make sure there is no damage to the tank.
Leaks:Check for any leaks from the fuel tanks.
Underbody of vehicle
Driveshaft:Make sure that the driveshaft is not bent or
cracked. Ensure all driveshaft couplings are
secure.
Exhaust system:Make sure the outside visible parts are
securely mounted. Make sure there are no
cracks, holes or severe dents.
Frame:Check for cracks or bends in longitudinal
frame members. Make sure there are no loose,
cracked, bent, broken or missing
crossmembers or crossmember fasteners.
Maintain adequate clearance between all parts of the exhaust
system and all hoses, wires and lines for engine cooling, brake
system, fuel system, power steering system and electrical system, Heat
damage to hoses, wires or lines may cause vehicle malfunction that
could result in property damage, personal injury or death.
Rear of vehicle
Air/Electric lines:
Make sure that air hoses are not cut, cracked,
chafed or worn. Listen for audible air leaks,
Make sure air and electrical lines are not
tangled, crimped or pinched or being dragged
against any truck parts. Electrical line insulation
should not be cut, cracked, chafed or worn.
None of the air or electrical line should be
spliced or taped. Check for corrosion on pins
and in electrical sockets to ensure continuity
and reduced heat build-up potential.
Deck plate:Make sure deck plate is clean, securely bolted
to the frame and clear of loose objects.

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 the Transmission Operator’s Manual for more information.
Charging system:Illuminates when
the battery is not charging properly.
Wait to start:Indicates the air
intake heater is in operation and
special starting procedures are
required. Refer to theDriving
chapter.
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 (if equipped):
During refueling it is possible for
water-contaminated diesel fuel to be
pumped into your fuel tank. Your
vehicle fuel system is equipped with
a fuel filter/water separator to remove water from the fuel. The indicator
light illuminates when the fuel filter/water separator has a significant
quantity of water, or when the ignition key is switched to the START
position. If the light illuminates when the engine is running, stop the
vehicle as soon as safely possible, shut off the engine and drain the filter
bowl. Allowing water to stay in the system could result in extensive
damage to, or failure of, the fuel injection system.
To drain the fuel filter/water separator (refer toMaintenance and
Specificationschapter for procedure), rotate the valve at the bottom of
the filter assembly allowing water to drain from the system. Close the
valve upon completion.

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 when the traction
control system is turned off.
Differential lock (if equipped):
Illuminates when the main
differential is locked (engaged).
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.
Key-in-ignition warning chime:Sounds when the key is left in the
ignition in the OFF/LOCK or ACC position and the driver’s door is
opened.
Headlamps on warning chime:Sounds when the headlamps or parking
lamps are on, the ignition is off (and the key is not in the ignition) and
the driver’s door is opened.
Instrumentation
25

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.
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.
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.
Air filter restriction gauge:
Measures the vacuum inside the air
cleaner. The more the air cleaner is
restricted (dirty, clogged), the
higher the vacuum reading. Change
the air filter when the gauge reads
25 inches. After installation of the
new filter element, reset the gauge
to 0.

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.
Air pressure gauge (if equipped):
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
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.
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.
