Vehicle Damage Warnings
Also, in this manual you will nd these notices:
Notice:These mean there is something
that could damage your vehicle.
A notice tells about something that can damage
the vehicle. Many times, this damage would not be
covered by your vehicle’s warranty, and it could
be costly. But the notice will tell what to do to help
avoid the damage.
When you read other manuals, you might see
CAUTION and NOTICE warnings in different colors
or in different words.
There are also warning labels on the vehicle.
They use the same words, CAUTION or NOTICE.
Vehicle Symbols
The vehicle has components and labels that use
symbols instead of text. Symbols are shown
along with the text describing the operation or
information relating to a specic component,
control, message, gage, or indicator.
If you need help guring out a specic name of a
component, gage, or indicator, reference the
following topics:

/(Remote Start):Press and release the lock
button and then press and hold the remote
start button to start the vehicle.
To start the vehicle using the remote start feature,
do the following:
1. Aim the transmitter at the vehicle.
2. Press and release the transmitter’s lock
button, then immediately press and hold
the transmitter’s remote start button until the
turn signal lights ash. If you cannot see
the vehicle’s lights, press and hold the remote
start button for at least four seconds. The
vehicle’s doors will lock. Pressing the remote
start button again after the vehicle has
started will turn off the ignition.
When the vehicle starts, the parking lamps will
turn on and remain on while the vehicle is
running.
3. If it is the rst remote start since the vehicle
has been driven, repeat these steps, while
the engine is still running, to extend the engine
running time by 10 minutes. Remote start
can be extended one time.After entering the vehicle during a remote start,
insert and turn the key to RUN to drive the vehicle.
If the vehicle is left running it will automatically
shut off after 10 minutes unless a time extension
has been done.
To manually shut off a remote start, do any of the
following:
Aim the RKE transmitter at the vehicle and
press the remote start button until the
parking lamps turn off.
Turn on the hazards warning ashers.
Turn the ignition switch on and then off.
The vehicle can be remote started two separate
times between driving sequences. The engine will
run for 10 minutes after each remote start.
Or, you can extend the engine run time by another
10 minutes within the rst 10 minute remote
start time frame, and before the engine stops.
For example, if the lock button and then the
remote start buttons are pressed again after
the vehicle has been running for ve minutes,
10 minutes are added, allowing the engine to run
for 15 minutes.

Warning Lights, Gages, and
Indicators
This part describes the warning lights and gages on
your vehicle. The pictures help to locate them.
Warning lights and gages can signal that something
is wrong before it becomes serious enough to
cause an expensive repair or replacement. Paying
attention to the warning lights and gages could also
save you or others from injury.
Warning lights come on when there may be or is a
problem with one of your vehicle’s functions. As
the details show on the next few pages, some
warning lights come on briey when you start the
engine just to let you know they are working. If
you are familiar with this section, you should
not be alarmed when this happens.Gages can indicate when there may be or is a
problem with one of your vehicle’s functions. Often
gages and warning lights work together to let
you know when there is a problem with your
vehicle.
When one of the warning lights comes on and
stays on as you are driving, or when one of
the gages shows there may be a problem, check
the section that tells you what to do about it.
Please follow this manual’s advice. Waiting to do
repairs can be costly and even dangerous. So
please get to know your vehicle’s warning
lights and gages. They can be a big help.
Your vehicle also has a Driver Information Center
(DIC) that works along with warning lights and
gages. SeeDIC Warnings and Messages
on page 281for more information.
248

Anti-Lock Brake System
Warning Light
With the Anti-Lock
Brake System (ABS),
this light will come on
when you start your
engine and may stay on
for several seconds.
That is normal. If the light does not come on then,
have it xed so it will be ready to warn you if
there is a problem.If the light stays on, or comes on when you are
driving, your vehicle needs service. A chime
will sound when the light stays on. If the regular
brake system warning light is not on, you still have
brakes, but you do not have ABS. If the regular
brake system warning light is also on you do
not have ABS and there is a problem with your
regular brakes. In addition to both lights, you
will also hear a chime sound on the rst
occurrence of a problem and each time the
vehicle is shut off and then restarted. SeeBrake
System Warning Light on page 258.
The ABS warning light should come on briey
when you turn the ignition key to RUN. If the light
does not come on then, have it xed so it will
be ready to warn you if there is a problem.
259

Avoid needless heavy braking. Some people drive
in spurts — heavy acceleration followed by
heavy braking — rather than keeping pace with
traffic. This is a mistake. The brakes may not have
time to cool between hard stops. The brakes
will wear out much faster if you do a lot of
heavy braking. If you keep pace with the traffic
and allow realistic following distances, you
will eliminate a lot of unnecessary braking.
That means better braking and longer brake life.
If your vehicle’s engine ever stops while you
are driving, brake normally but do not pump the
brakes. If you do, the pedal may get harder
to push down. If the engine stops, you will still
have some power brake assist. But you will use it
when you brake. Once the power assist is used
up, it may take longer to stop and the brake pedal
will be harder to push.
Adding non-GM accessories can affect your
vehicle’s performance. SeeAccessories and
Modications on page 488.Anti-Lock Brake System (ABS)
Your vehicle has the Anti-Lock Brake System
(ABS), an advanced electronic braking system that
will help prevent a braking skid.
When you start your engine and begin to drive
away, ABS will check itself. You may hear a
momentary motor or clicking noise while this test
is going on. This is normal.
If there is a problem
with ABS, this warning
light will stay on.
SeeAnti-Lock Brake
System Warning
Light on page 259.
Along with ABS, your vehicle has a Dynamic Rear
Proportioning (DRP) system. If there is a DRP
problem, both the brake and ABS warning lights
will come on accompanied by a 10-second
chime. The lights and chime will come on each
time the ignition is turned on until the problem is
repaired. See your dealer for service.

Traction Control Operation
The traction control system is part of the
StabiliTrak®system. Traction control limits wheel
spin by reducing engine power to the wheels
(engine speed management) and by applying
brakes to each individual wheel (brake-traction
control) as necessary.
The traction control system is enabled
automatically when you start your vehicle. It will
activate and the StabiliTrak
®light will ash if
it senses that any of the wheels are spinning or
beginning to lose traction while driving. If you
turn off traction control, only the brake-traction
control portion of traction control will work.
The engine speed management will be disabled.
In this mode, engine power is not reduced
automatically and the driven wheels can spin more
freely. This can cause the brake-traction control
to activate constantly.
Notice:If you allow the wheel(s) of one axle
to spin excessively while the StabiliTrak
®, ABS
and brake warning lights and the SERVICE
STABILITRAK message are displayed,
you could damage the transfer case.The repairs would not be covered by your
warranty. Reduce engine power and do
not spin the wheel(s) excessively while these
lights and this message are displayed.
The traction control system may activate on
dry or rough roads or under conditions such as
heavy acceleration while turning or abrupt
upshifts/downshifts of the transmission. When this
happens, you may notice a reduction in
acceleration, or may hear a noise or vibration.
This is normal.
If your vehicle is in cruise control when the system
activates, the StabiliTrak
®light will ash and the
cruise control will automatically disengage.
When road conditions allow you to use cruise
again, you may re-engage the cruise control.
SeeCruise Control on page 220.
StabiliTrak
®may also turn off automatically if it
determines that a problem exists with the system.
If the problem does not clear itself after restarting
the vehicle, you should see your dealer for service.
386

Consistency of Readings
Always check the uid level at least twice using
the procedures described. Consistency (repeatable
readings) is important to maintaining proper uid
level. If uid is added, it may take 15 minutes
or longer to obtain an accurate reading because of
residual uid draining down the dipstick tube. If
inconsistent readings persist, check the
transmission breather to be sure it is clean and
not clogged. If readings are still inconsistent,
contact your dealer.
Engine Coolant
If your vehicle has the DURAMAX®Diesel engine,
see the DURAMAX®Diesel manual for more
information.
The cooling system in your vehicle is lled with
DEX-COOL
®engine coolant. This coolant is
designed to remain in your vehicle for ve years or
150,000 miles (240 000 km), whichever occurs
rst, if you add only DEX-COOL
®extended
life coolant.The following explains your cooling system and
how to add coolant when it is low. If you have
a problem with engine overheating, seeEngine
Overheating on page 517.
A 50/50 mixture of clean, drinkable water and
DEX-COOL
®coolant will:
Give freezing protection down to
−34°F (−37°C).
Give boiling protection up to 265°F (129°C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights and gages work as they
should.
Notice:Using coolant other than DEX-COOL
®
may cause premature engine, heater core, or
radiator corrosion. In addition, the engine
coolant may require changing sooner, at the
rst maintenance service after each
30,000 miles (50 000 km) or 24 months,
whichever occurs rst. Any repairs would not
be covered by your warranty. Always use
DEX-COOL
®(silicate-free) coolant in your
vehicle.
