Parking Brake Warning Light
This light will also come on when you set the
parking brake. The light will stay on if your parking
brake does not release fully.
Air Brake System Warning Light
Vehicles with air brake systems have a brake
system warning light on the instrument panel.
The LOW AIR warning light should come on, as a
check, whenever you start the engine. However,
it is designed to come on, and stay on, when brake
reservoir pressure has dropped below 60 psi
(410 kPa).When the warning light comes on while you are
driving, you should drive only as far as the nearest
point of safety and then stop the vehicle. Here’s
a very important thing for you to know:{CAUTION:
If the air brake system warning light
comes on and the warning tone sounds,
the vehicle can stop suddenly and without
further warning. This is because the
parking brake will come on if the pressure
falls below 35 to 45 psi (240 to 310 kPa).
You or others could be injured. If the air
brake system warning light comes on and
the warning tone sounds, stop as soon as
you can. You will not know how quickly
the system is losing pressure, so be
aware that the parking brake may come
on suddenly.

Anti-Lock Brake System
Warning Light
This light will come on
briefly when you start
your engine, then
it will turn off. This
is normal.
If the light stays on, or comes on when you are
driving, your vehicle needs service. If the BRAKE
or LOW AIR warning light is not on, you still
have brakes, but you do not have the anti-lock
brake feature. If the BRAKE and/or LOW AIR
warning light is on, you do not have anti-lock
brakes and there is a problem with your regular
brakes. SeeBrake System Warning Light on
page 169andAnti-Lock Brake System (ABS) on
page 212for more information.
The anti-lock brake system warning light should
come on briefly when you turn the ignition
key to ON. If the light does not come on then,
have it fixed so it will be ready to warn you if
there is a problem.
Trailer Anti-Lock Brake System
Warning Light
This light is located
above the climate
controls in the center of
the instrument panel.
If your vehicle is connected to a trailer with
anti-lock brakes, this light should come on briefly,
as a check, when you turn on the ignition.
When this light comes on and stays on, it means
there is something wrong in the trailer anti-lock
brake system. Have the system repaired
immediately.
If an anti-lock brake system equipped trailer is not
connected, this light is not functional.

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 288. If you have
a Caterpillar
®diesel engine, also see your
Caterpillar®Operation & Maintenance Manual.
Low Coolant Warning Light
You have a low coolant
warning light. If this light
comes on, your 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 at several beats per second for 10 seconds.
SeeEngine Coolant (Gas and DURAMAX
®/Isuzu
Engines) on page 284orEngine Coolant
(Caterpillar
®Diesel Engines) on page 287and
have your vehicle serviced as soon as you can.
This light may also come on if your vehicle is
equipped with the automatic engine shutdown
system and engine shutdown has begun.

it will have an inlet heater.
The light in the center of
the instrument panel will
come on when the inlet
heater or glow plugs are
on and the ignition key is
in RUN.
Wait until the indicator light goes off before turning
the ignition key to START.
Malfunction Indicator Lamp
Service Engine Soon Light
If this light comes on or
flashes while you are
driving, two things
may happen.
First, you will not notice any difference in engine
performance, but your tail pipe emissions may
increase. Second, your engine may not run
properly or may stall without warning. If either of
these things happen, drive or tow your vehicle
to your dealer for service.
This light should come on when the ignition is on,
but the engine is not running, as a check to
show you it is working. If it does not come on at
all, have it repaired.
Notice:If you keep driving your vehicle with
this light on, after awhile, your emission
controls may not work as well, your fuel
economy may not be as good, and your engine
may not run as smoothly. This could lead to
costly repairs that may not be covered by your
warranty.

Transmission Temperature Gage
If you have an automatic
transmission and this
gage, it is located above
the switchbank in the
center of the instrument
panel.
When your ignition is on, the gage shows the
temperature of the transmission oil. A reading in
the warning zone, the red area beginning at 300°F
(150°C), means you must stop driving and
check into the cause. One possible cause is a low
oil level in the transmission.
Notice:If you drive your vehicle with the
transmission temperature gage above normal
operating range, you can damage the
transmission. This could lead to costly repairs
that would not be covered by your warranty.
Do not drive your vehicle while the
transmission temperature gage reading is
above normal. See your dealer for service.
Exhaust Brake Indicator Light
If your vehicle is
equipped with an
exhaust brake, you will
have this light, located
above the climate
controls in the center of
the instrument panel.
The exhaust brake indicator light will come on and
stay on whenever the diesel engine exhaust brake
or exhaust restrictor is active. For more information,
seeDiesel Engine Exhaust Brake on page 112and
Exhaust Restrictor (Engine Warm-Up) on page 108.
Differential Lock Indicator Light
If your vehicle has this
feature, this light is
located in the center of
the instrument panel.
The light is on when the

This light will come on when your vehicle is low on
windshield washer fluid.
For more information, seeWindshield Washer
Fluid on page 296.
Check Gages Warning Light
This light will come on
as you’re starting the
engine, just as a check.
If this light comes on and stays on while you are
driving. It means that either your engine coolant
temperature gage or your engine oil pressure gage
may be showing a reading in the warning zone.
When the check gages light comes on, you
will also hear a warning tone. The tone and the
light will stay activated until the problem is
corrected.
This light may also come on if your vehicle is

Water in Fuel Warning Light
This light is located
above the climate
controls in the center of
the instrument panel.
If your vehicle has the 6.6L DURAMAX
®or Isuzu
6H diesel engine, this light will come on to
warn you that there is water in the fuel system.
For more information on how this light works, see
Water in Fuel on page 256.
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 25 inches of
vacuum on the scale, 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.
182

Air Pressure Gage
If your vehicle has air
brakes, the air pressure
gage is located above
the switchbank in
the center of the
instrument panel.
This gage shows the air pressure for both your
front and rear brake systems.
If the needle on the gage indicates that the air
pressure is below 60 to 75 psi (415 to 517 kPa),
the low air warning light will come on. An alarm will
also sound if this happens.The top pointer shows the pressure available for the
front system, while the bottom pointer shows
pressure for the rear. There should be no more than
4 psi (28 kPa) difference showing between the
systems.
Don’t drive until both pointers are showing at least
120 psi (827 kPa), so you’ll have enough air if
you need to apply your brakes.
Hourmeter Gage
To access the engine hourmeter gage, press the
trip odometer button three times.
The instrument panel cluster displays the
accumulated engine run time hours using the
reconfigurable odometer display. The engine run
time hours displays only when the ignition is in the
LOCK or ACCESSORY position and the trip
reset button is pressed for about four seconds.
The value of the accumulated hours does
not change when the battery is disconnected.
The hourmeter resets to 0.0 when 10,000 hours
are accumulated. The instrument panel cluster
begins to reaccumulate the engine run time hours
from 0.0 hours.
183

Control of a Vehicle
You have three systems that make your vehicle go
where you want it to go. They are the brakes, the
steering, and the accelerator. All three systems
have to do their work at the places where the tires
meet the road.
Sometimes, as when you are driving on snow or
ice, it is easy to ask more of those control systems
than the tires and road can provide. That means
you can lose control of your vehicle.
Braking
SeeBrake System Warning Light on page 169.
Braking action involves perception time and
reaction time.
First, you have to decide to push on the brake
pedal. That is perception time. Then you have to
bring up your foot and do it. That is reaction time.Average reaction time is about three-fourths of
a second. But that is only an average. It might
be less with one driver and as long as two or
three seconds or more with another. Age,
physical condition, alertness, coordination and
eyesight all play a part. So do alcohol, drugs
and frustration. But even in three-fourths of
a second, a vehicle moving at 60 mph (100 km/h)
travels 66 feet (20 m). That could be a lot of
distance in an emergency, so keeping enough
space between your vehicle and others is
important.
And, of course, actual stopping distances vary
greatly with the surface of the road, whether it is
pavement or gravel; the condition of the road,
whether it is wet, dry or icy; tire tread; the condition
of the brakes; the weight of the vehicle; the
weight of the load; and the amount of brake
force applied.
