Parking Brake Adjustment (Hand Lever
System Only)
Make sure the parking brake burnish procedure has
been previously followed before continuing with any park
brake adjustment. SeeParking Brake Burnish
Procedure on page 2-43for more information. Parking
brake adjustment may be necessary after the burnish
procedure or at the scheduled maintenance intervals.
If the vehicle is has a hand-lever park brake system, an
in-cab adjustment may be made to the park brake
system. This will adjust the parking brake holding force.
The adjustment is made with the knob located at the
end of the hand lever.
To make an adjustment:
1. Press and hold the regular brake pedal
2. Release the parking brake
3. Turn the knob only up to a half turn to the left, top
of knob toward the driver. This will increase the
holding force of the system.

4. Check to see if the vehicle moves by slowly
removing your foot from the regular brake pedal.
5. If the vehicle moves, press the regular brake and
repeat the adjustment procedure.
Notice:Over-tightening the park brake lever can
cause damage to the park brake system.
Over-tightening is possible by turning the knob
more than half a turn.
Over-tightening is similar to driving down the road with
your regular brakes applied. If your park brake system is
over-tightened your vehicle may seem sluggish to
accelerate, and/or your park brake hand lever maybe
very hard to pull up and apply the park brake.
If the park brake is over-tightened turn the knob to the
left until it stops and follow the parking brake adjustment
procedure.
Vehicles with a foot-pedal park brake system must be
serviced to make this adjustment. SeeScheduled
Maintenance on page 6-5for more information.Parking Brake (With Air Brakes)
If your vehicle has air
brakes, you will have this
parking brake. It is located
above the audio system in
the instrument panel.
Pulling it out applies the parking brake. The parking
brake light will come on when the air parking brake
is applied.

Engine Coolant Temperature Gage
This gage shows the
engine coolant
temperature. If the gage
pointer moves into the
red area, your engine
coolant might have
overheated and your
engine may be too hot.
You should pull off the road, stop your vehicle and turn
off the engine as soon as possible.
SeeEngine Overheating on page 5-48. If you have a
Caterpillar
®diesel engine, also see your Caterpillar®
Operation & Maintenance Manual.
Low Coolant Warning Light
Your vehicle has a low
coolant warning light.
If this light comes on, the
system is low on coolant
and the engine may
overheat.
The warning light should come on briefly, as a check,
when you turn on the ignition.
When it comes on, you will also hear a warning tone for
10 seconds. SeeEngine Coolant (Caterpillar
®Diesel
Engines) on page 5-44orEngine Coolant (Gas and
DURAMAX
®/Isuzu 7.8L L6 Engines) on page 5-44
Engine Coolant and have your vehicle serviced as
soon as you can.
This light may also come on if your vehicle has the
automatic engine shutdown system and engine
shutdown has begun. SeeEngine Alarm and Automatic
Shutdown on page 2-18for more information.

Oil Pressure Gage
The engine oil pressure
gage, on the lower right
portion of your instrument
panel cluster, shows
engine oil pressure in
psi (pounds per square
inch) or in kPa
(kilopascals).
Oil pressure may vary with outside temperature and oil
viscosity, but readings of 30 to 40 psi (205 to 275 kPa)
on gasoline engines at operating temperature and
moderate road speeds are normal. If you have a diesel
engine, the normal operating range should be between
35 and 70 psi (240 to 480 kPa).A reading in the low pressure zone may be caused by a
dangerously low oil level or other problem.
If you have a Caterpillar®diesel engine, also see your
Caterpillar®Operation & Maintenance Manual.
{CAUTION:
Do not keep driving if the oil pressure is low.
If you do, your engine can become so hot that
it catches re. You or others could be burned.
Check your oil as soon as possible and have
your vehicle serviced.
Notice:Lack of proper engine oil maintenance
may damage the engine. The repairs would not be
covered by your warranty. Always follow the
maintenance schedule in this manual for changing
engine oil.
3-37

Low Oil Level Light
Your vehicle may have a
low oil level light.
This light should come on as a check, when you start
your engine. If the light fails to come on, have it repaired
as soon as possible so you will be aware when the oil
level is low.
Vehicles that have Caterpillar
®diesel engines may not
have a low oil level light. In this case, the light will
neither come on as a check when you start your engine,
nor will it come on to indicate a low oil level.
If this light comes on and stays on, it means your
engine is low on oil. You need to check the oil level
right away. SeeEngine Oil (Caterpillar
®Diesel Engine)
on page 5-23orEngine Oil (Gasoline Engine) on
page 5-24orEngine Oil (DURAMAX
®Diesel Engine) on
page 5-28orEngine Oil (Isuzu Diesel Engine) on
page 5-32for further information.
Notice:Lack of proper engine oil maintenance may
damage the engine. The repairs would not be covered
by your warranty. Always follow the maintenance
schedule in this manual for changing engine oil.
Change Engine Oil Light
The change engine oil light
should come on briefly as
a bulb check when you
start the engine. If the light
does not come on, have
it serviced.
If the change engine oil light comes on and stays on
after you start the engine, have the oil changed.

for gasoline engines or DURAMAX
®diesel engines,

Fuel Gage
Your fuel gage is located
on the right side of your
instrument panel cluster.
When the ignition is on, your fuel gage lets you know
about how much fuel you have left. When the gage first
shows empty, you’ll still have a little fuel left, but you
should get more fuel soon.
If your vehicle has dual fuel tanks, the reading on the
gage is the total fuel left in both tanks.Here are four concerns of some operators. None of
these shows a problem with your fuel gage:•The gage moves a little when you turn a corner or
speed up.
•The gage does not go back to empty when you
turn off the ignition.
•At the gas station, the pump shuts off before the
gage reads full.
•It takes a little more or less fuel to fill up than the
gage indicated.
If you have a Caterpillar
®diesel engine, also see your
Caterpillar®Operation & Maintenance Manual.

Diesel Particulate Filter
Warning Light
Your vehicle may have
two Diesel Particulate
Filter (DPF) Warning lights.
These lights will come on briefly when the ignition is
turned to ON. One of these lights will come on
green during DPF regeneration. If the other light comes
on yellow, perform a manual regeneration or drive
the vehicle for automatic regeneration. If the light
changes from yellow to red, the DPF requires an
immediate regeneration. If the DPF is not regenerated,
the service engine soon light will come on and engine
power will be reduced.
SeeDiesel Particulate Filter (Diesel Engine) on
page 2-46andReduced Engine Power Light on
page 3-41for more information.
Air Filter Restriction Indicator
If your vehicle has this
feature, the gage is
located above the
switchbank in the center
of the instrument panel.
It monitors the engine
air filter.
As the filter gets dirty, the yellow indicator will begin to
rise. When it reaches the red/orange change area,
the filter should be replaced.
After replacing the filter, reset the gage by pressing in
the yellow reset button at the bottom of the gage.
If you have a Caterpillar
®diesel engine, also see your
Caterpillar®Operation & Maintenance Manual.
