StabiliTrak®System
The vehicle is equipped with a vehicle stability
enhancement system called StabiliTrak. It is an advanced
computer controlled system that assists with directional
control of the vehicle in difficult driving conditions.
StabiliTrak activates when the computer senses a
discrepancy between the intended path and the direction
the vehicle is actually traveling. StabiliTrak selectively
applies braking pressure at any one of the vehicle’s
brakes to help steer the vehicle in the intended direction.
When the stability control system activates, the Traction
Control System (TCS)/StabiliTrak light will ash on the
instrument panel. This also occurs when traction control
is activated. A noise may be heard or vibration may be
felt in the brake pedal. This is normal. Continue to steer
the vehicle in the intended direction.
If there is a problem detected with StabiliTrak, a
SERVICE STABILITRAK message will be displayed on
the Driver Information Center (DIC). SeeDIC Warnings
and Messages on page 3-51. When this message is
displayed, the system is not operational. Driving should
be adjusted accordingly.
StabiliTrak comes on automatically whenever the vehicle
is started. To assist with directional control of the vehicle,
the system should always be left on. StabiliTrak canbe turned off if needed by pressing and holding the
TCS/StabiliTrak button until the TCS/StabiliTrak light
comes on the instrument panel and STABILITRAK OFF
appears in the DIC. For information on turning TCS off
and on, see Traction Control System (TCS) following.
If cruise control is being used when StabiliTrak activates,
the cruise control will automatically disengage. Cruise
control may be reengaged when road conditions allow.
SeeCruise Control on page 3-12for more information.
Traction Control System (TCS)
The vehicle has a traction control system that limits wheel
spin. This is especially useful in slippery road conditions.
On a rear-wheel-drive vehicle, the system operates if it
senses that one or both of the rear wheels are spinning or
beginning to lose traction. On an All-Wheel-Drive (AWD)
vehicle, the system will operate if it senses that any of the
wheels are spinning or beginning to lose traction. When
this happens, the system brakes the spinning wheel(s)
and/or reduces engine power to limit wheel spin.
The system may be heard or felt while it is working, but
this is normal.
The TCS warning light will also ash to indicate that the
traction control system is active.

This warning light comes
on if there is a problem
with the traction control
system.
SeeTraction Control System (TCS) Warning Light on
page 3-37. When this warning light is on, the system will
not limit wheel spin. Adjust your driving accordingly.
TCS automatically comes on whenever the vehicle
is started. To limit wheel spin, especially in slippery
road conditions, the system should always be left on.
But, TCS can be turned off if needed.
Notice:Do not repeatedly brake or accelerate
heavily when TCS is off. The vehicle’s driveline
could be damaged.
When TCS is switched off on AWD vehicles, the system
may still make noise. This is normal and necessary
with the AWD hardware on the vehicle.It may be necessary to turn the system off if the vehicle
ever gets stuck in sand, mud or snow and rocking the
vehicle is required. SeeRocking Your Vehicle to Get It
Out on page 4-30andIf Your Vehicle is Stuck in Sand,
Mud, Ice, or Snow on page 4-29for more information.
See alsoWinter Driving on page 4-27for information on
using TCS when driving in snowy or icy conditions.
To turn the system off,
press the TCS/StabiliTrak
®
button located on the
console under the climate
controls.
Press and release the TCS/StabiliTrak button and the
traction control system will turn off and the traction
control system warning light will come on. Press
the button again to turn the system back on.
For information on turning StabiliTrak off and on,
see StabiliTrak System previously.
Adding non-GM accessories can affect the vehicle’s
performance. SeeAccessories and Modifications
on page 5-3for more information.

Off-Road Recovery
The vehicle’s right wheels can drop off the edge of a
road onto the shoulder while driving.
If the level of the shoulder is only slightly below the
pavement, recovery should be fairly easy. Ease off the
accelerator and then, if there is nothing in the way, steer
so that your vehicle straddles the edge of the pavement.
Turn the steering wheel 3 to 5 inches, 8 to 13 cm, (about
one-eighth turn) until the right front tire contacts the
pavement edge. Then turn the steering wheel to go
straight down the roadway.
Passing
Passing another vehicle on a two-lane road can be
dangerous. To reduce the risk of danger while passing:
Look down the road, to the sides, and to crossroads
for situations that might affect a successful pass.
If in doubt, wait.
Watch for traffic signs, pavement markings, and
lines that could indicate a turn or an intersection.
Never cross a solid or double-solid line on your side
of the lane.
Do not get too close to the vehicle you want to
pass. Doing so can reduce your visibility.
Wait your turn to pass a slow vehicle.
When you are being passed, ease to the right.
Loss of Control
Let us review what driving experts say about what
happens when the three control systems — brakes,
steering, and acceleration — do not have enough friction
where the tires meet the road to do what the driver has
asked.
In any emergency, do not give up. Keep trying to steer
and constantly seek an escape route or area of less
danger.

Driving Downhill
When off-roading takes you downhill, consider:
How steep is the downhill? Will I be able to maintain
vehicle control?
What is the surface like? Smooth? Rough?
Slippery? Hard-packed dirt? Gravel?
Are there hidden surface obstacles? Ruts? Logs?
Boulders?
What is at the bottom of the hill? Is there a hidden
creek bank or even a river bottom with large rocks?
If you decide you can go down a hill safely, try to keep
the vehicle headed straight down. Use a low gear
so engine drag can help the brakes so they do not
have to do all the work. Descend slowly, keeping the
vehicle under control at all times.
{CAUTION:
Heavy braking when going down a hill can cause
your brakes to overheat and fade. This could cause
loss of control and a serious accident. Apply the
brakes lightly when descending a hill and use a low
gear to keep vehicle speed under control.Things not to do when driving down a hill:
When driving downhill, avoid turns that take you
across the incline of the hill. A hill that is not too
steep to drive down might be too steep to drive
across. The vehicle could roll over.
Never go downhill with the transmission in
N (Neutral), called free-wheeling. The brakes
will have to do all the work and could overheat
and fade.
Vehicles are much more likely to stall when going uphill,
but if it happens when going downhill:
1. Stop the vehicle by applying the regular brakes and
apply the parking brake.
2. Shift to P (Park) and, while still braking, restart the
engine.
3. Shift back to a low gear, release the parking brake,
and drive straight down.
4. If the engine will not start, get out and get help.

Driving in Rain and on Wet Roads
Rain and wet roads can reduce vehicle traction and affect
your ability to stop and accelerate. Always drive slower
in these types of driving conditions and avoid driving
through large puddles and deep-standing or owing
water.
{CAUTION:
Wet brakes can cause crashes. They might not
work as well in a quick stop and could cause pulling
to one side. You could lose control of the vehicle.
After driving through a large puddle of water or a
car/vehicle wash, lightly apply the brake pedal until
the brakes work normally.
Flowing or rushing water creates strong forces.
Driving through owing water could cause your
vehicle to be carried away. If this happens, you and
other vehicle occupants could drown. Do not ignore
police warnings and be very cautious about trying to
drive through owing water.
Hydroplaning
Hydroplaning is dangerous. Water can build up under
your vehicle’s tires so they actually ride on the water.
This can happen if the road is wet enough and you are
going fast enough. When your vehicle is hydroplaning, it
has little or no contact with the road.
There is no hard and fast rule about hydroplaning.
The best advice is to slow down when the road is wet.
Other Rainy Weather Tips
Besides slowing down, other wet weather driving tips
include:
Allow extra following distance.
Pass with caution.
Keep windshield wiping equipment in good shape.
Keep the windshield washer uid reservoir lled.
Have good tires with proper tread depth. SeeTires
on page 5-48.
Turn off cruise control.

Tow/Haul Mode
Pressing this button at
the end of the shift lever
turns on and off the
tow/haul mode.
This indicator light on the
instrument panel cluster
comes on when the
tow/haul mode is on.
Tow/Haul is a feature that assists when pulling a heavy
trailer or a large or heavy load. SeeTow/Haul Mode
on page 2-31.
Tow/Haul is designed to be most effective when
the vehicle and trailer combined weight is at least
75 percent of the vehicle’s Gross Combined WeightRating (GCWR). See “Weight of the Trailer” later
in the section. Tow/Haul is most useful under the
following driving conditions:
When pulling a heavy trailer or a large or heavy
load through rolling terrain.
When pulling a heavy trailer or a large or heavy
load in stop and go traffic.
When pulling a heavy trailer or a large or heavy
load in busy parking lots where improved low
speed control of the vehicle is desired.
Operating the vehicle in Tow/Haul when lightly loaded or
with no trailer at all will not cause damage. However,
there is no bene t to the selection of Tow/Haul when the
vehicle is unloaded. Such a selection when unloaded
may result in unpleasant engine and transmission driving
characteristics and reduced fuel economy. Tow/Haul is
recommended only when pulling a heavy trailer or a large
or heavy load.
Trailer Brakes
A loaded trailer that weighs more than 1,000 lbs (900 kg)
needs to have its own brake system that is adequate for
the weight of the trailer. Be sure to read and follow the
instructions for the trailer brakes so they are installed,
adjusted and maintained properly. Because the vehicle
has StabiliTrak, do not try to tap into the vehicle’s
hydraulic brake system. If you do, both brake systems will
not work well, or at all.
