If the door does not travel to the fully open position,
press the overhead console switch to the override
(deactivation) position and slide the door fully open and
closed. Check for foreign objects in the tracks. Repeat
the procedure starting with Step 1. If the door resists
travel to the fully open position, see your dealer
for service.
Liftgate
To unlock or lock the liftgate from the outside, use the
remote keyless entry transmitter. For more information,
seeRemote Keyless Entry System Operation on
page 2-5. You can also use the power door lock switch
to lock and unlock the liftgate.
Open the liftgate using the handle located above the
license plate. Once slightly opened, the liftgate will rise
by itself. Lamps in the rear of the vehicle will come
on, illuminating the rear cargo area.
Notice:If you open the liftgate without checking for
overhead obstructions such as a garage door,
you could break the liftgate glass. Always check to
make sure the area above the liftgate is clear
before opening it.
{CAUTION:
It can be dangerous to drive with the liftgate
open because carbon monoxide (CO) gas can
come into your vehicle. You cannot see or
smell CO. It can cause unconsciousness and
even death. If you must drive with the liftgate
open or if electrical wiring or other cable
connections must pass through the seal
between the body and the liftgate:
Make sure all other windows are shut.
Turn the fan on your heating or cooling
system to its highest speed and select the
control setting that will force outside air
into your vehicle. SeeClimate Control
System on page 3-25.
If you have air outlets on or under the
instrument panel, open them all the way.

Traction Control System (TCS)
Warning Light
Your vehicle is equipped
with a traction control
system warning light.
The traction control system warning light may come on
for the following reasons:
If you turn the system off by pressing the traction
control button. To turn the system back on, press
the button again. The warning light should go
off. SeeTraction Control System (TCS) on page 4-9
for more information.
If there’s a brake system problem that is speci cally
related to traction control, the traction control
system will turn off and the warning light will come
on. If your brakes begin to overheat, the traction
control system will turn off and the warning light will
come on until your brakes cool down.
If the traction control system is affected by an
engine-related problem, the system will turn off and
the warning light will come on.If the traction control system warning light comes on
and stays on for an extended period of time when the
system is turned on, your vehicle needs service.
Engine Coolant Temperature Gage
This gage shows the engine coolant temperature. If the
red gage lamp turns on, your engine is too hot!
It means that your engine coolant has overheated. If
you have been operating your vehicle under normal
driving conditions, you should pull off the road, stop your
vehicle and turn off the engine as soon as possible.
SeeEngine Overheating on page 5-25.

If there are any active warning messages when the
vehicle is turned off, two chimes will sound and the DIC
will go into a reminder mode. The reminder mode
displays any active message. If there are multiple
messages, the DIC will display each message for
ve seconds. After each active message is displayed
once, the reminder mode will turn off.
You should take any messages that appear on the
display seriously and remember that clearing the
messages will only make the messages disappear, not
correct the problem.
The following are the possible messages that can be
displayed and some information about them.
A/C OFF FOR ENGINE PROTECTION
This message will display when the engine coolant
becomes hotter than the normal operating temperature.
SeeEngine Coolant Temperature Gage on page 3-39.
To avoid added strain on a hot engine, the air
conditioning compressor is automatically turned off.
When the coolant temperature returns to normal, the air
conditioning compressor will turn back on. You can
continue to drive your vehicle.
This message will come on while the ignition is in RUN.
Press any of the DIC buttons to acknowledge this
warning message and to clear it from the screen.This message will continue to display for two seconds if
it has not been acknowledged when the engine is
turned off. It will also re-display for two seconds if the
message has been acknowledged, but the condition still
exists when the engine is turned off.
If the condition still exists, the message will re-appear
when the engine is turned on. If this message continues
to appear, have the system repaired by your GM dealer
as soon as possible to avoid damage to your engine.
ALL WHEEL DRIVE DISABLED
If your vehicle has the all-wheel drive system, this
message will display when there is a spare tire on the
vehicle, or when the anti-lock brake system warning light
comes on, or when the rear differential uid is
overheating. This message will turn off when the
differential uid cools.
The all-wheel drive system will be disabled until the
compact spare tire is replaced by a full-size tire. If the
warning message is still on after putting on the full-size
tire, you need to reset the warning message. To
reset the warning message, turn the ignition off and
then back on again. If the message stays on, see your
GM dealer right away. SeeAll-Wheel Drive (AWD)
System on page 4-12for more information.
3-52
This message will display while the ignition is in RUN. A
chime will sound when the ignition is shifted out of
PARK (P). Press any of the DIC buttons to acknowledge
this message and to clear it from the screen.
This message will continue to display for two seconds if
it has not been acknowledged when the engine is
turned off. It will also re-display for two seconds if the
message has been acknowledged, but the condition still
exists when the engine is turned off.
If the condition still exists, the message will re-appear
when the engine is turned on.
ENGINE COOLANT HOT
Notice:If you drive your vehicle while the engine is
overheating, severe engine damage may occur. If
an overheat warning appears on the instrument
panel cluster and/or DIC, stop the vehicle as soon
as possible. Do not increase the engine speed above
normal idling speed. SeeEngine Overheating on
page 5-25for more information.
This message will display when the engine coolant
temperature is too hot. The engine coolant temperature
warning light will also appear on the instrument panel
cluster. SeeEngine Coolant Temperature Gage on
page 3-39for more information.To avoid added strain on the engine, turn off the air
conditioner if it is on. When the coolant temperature
returns to normal, the air conditioner can be turned
back on.
This message will display only when the ignition is in
RUN. A chime will sound continuously when this
message is displayed. Press any of the DIC buttons to
acknowledge this message and to clear it from the
screen.
This message will continue to display for two seconds if
it has not been acknowledged when the engine is
turned off. It will also re-display for two seconds if the
message has been acknowledged, but the condition still
exists when the engine is turned off.
If the condition still exists, the message will re-appear
when the engine is turned on.
HEADLAMPS SUGGESTED
This message will display when the amount of available
light outside of the vehicle is low, or the windshield
wipers have been on for approximately 30 seconds, and
the exterior lamps control is off or in the park lamps
position. This message informs the driver that turning on
the exterior lamps is recommended. SeeExterior
Lamps on page 3-14for more information.
This message will display while the ignition is in RUN.
Press any of the DIC buttons to acknowledge this
message and to clear it from the screen.

If the brake traction-control system activates constantly
or if the brakes have heated up due to high-speed
braking, brake traction-control will be disabled and the
TRACTION CONTROL ACTIVE message will be
displayed. In the limited mode, the traction control
system will only use engine traction-control and is limited
in its ability to provide optimal performance since the
system will not utilize brake traction-control to control
slip on the drive wheels. The system will return to normal
operation after the brakes have cooled. This can take
up to two minutes or longer depending on brake usage.
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 STABILITY CONTROL ACTIVE message
will appear on the DIC 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 3-10.
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.
All-Wheel Drive (AWD) System
If your vehicle has all-wheel drive (AWD), the AWD
system operates automatically without any action
required by the driver. If the front drive wheels begin to
slip, the rear wheels will automatically begin to drive
the vehicle as required. There may be a slight
engagement noise during hard use but this is normal.
During heavy AWD applications, the engine torque may
be reduced to protect AWD system components. If
the vehicle is exposed to extended heavy AWD usage,
the AWD system will shut itself off to protect the
system from overheating. When the system cools down,
the AWD system will activate itself again automatically;
this cool-down can take up to 20 minutes depending
on outside temperature and vehicle use.

Driving with a Trailer
{CAUTION:
If you have a rear-most window open and you
pull a trailer with your vehicle, carbon
monoxide (CO) could come into your vehicle.
You cannot see or smell CO. It can cause
unconsciousness or death. SeeEngine
Exhaust on page 2-41. To maximize your safety
when towing a trailer:
Have your exhaust system inspected for
leaks, and make necessary repairs before
starting on your trip.
Keep the rear-most windows closed.
If exhaust does come into your vehicle
through a window in the rear or another
opening, drive with your front, main
heating or cooling system on and with the
fan on any speed. This will bring fresh,
outside air into your vehicle. Do not use
the climate control setting for maximum air
because it only recirculates the air inside
your vehicle. SeeClimate Control System
on page 3-25.Towing a trailer requires a certain amount of experience.
Before setting out for the open road, you will want to
get to know your rig. Acquaint yourself with the feel of
handling and braking with the added weight of the trailer.
And always keep in mind that the vehicle you are
driving is now a good deal longer and not nearly as
responsive as your vehicle is by itself.
Before you start, check all trailer hitch parts and
attachments, safety chains, electrical connector, lamps,
tires, and mirror adjustment. If the trailer has electric
brakes, start your vehicle and trailer moving and
then apply the trailer brake controller by hand to be sure
the brakes are working. This lets you check your
electrical connection at the same time.
During your trip, check occasionally to be sure that the
load is secure, and that the lamps and any trailer
brakes are still working.
