Road Sensing Suspension The Road Sensing Suspension (RSS) feature provides
superior vehicle ride and handling under a variety of
passenger and loading conditions.
The system is fully automatic and uses a computer
controller to continuously monitor vehicle speed, wheel
to body position, lift/dive and steering position of the
vehicle. The controller then sends signals to each shock
absorber to independently adjust the damping level to
provide the optimum vehicle ride.
RSS also interacts with the tow/haul mode that, when
engaged, will provide additional control of the shock
absorbers. This additional control results in better ride
and handling characteristics when the vehicle is
loaded or towing a trailer. See “Tow/Haul Mode” under
Towing a Trailer on page 4-44 .
StabiliTrak ®
SystemYour vehicle may have the StabiliTrak ®
system which
combines antilock brake, traction and stability control
systems and helps the driver maintain directional control
of the vehicle in most driving conditions. When you rst start your vehicle and begin to drive
away, the system performs several diagnostic checks to
ensure there are no problems. You may hear or feel
the system working. This is normal and does not mean
there is a problem with your vehicle. The system
should initialize before the vehicle reaches 20 mph
(32 km/h). In some cases, it may take approximately
two miles of driving before the system initializes.
If the system fails to turn on or activate, the StabiliTrak ®
light along with one of the following messages will be
displayed on the Driver Information Center (DIC):
TRACTION CONTROL OFF, SERVICE TRACTION
CONTROL, STABILITRAK OFF, SERVICE
STABILITRAK. If these DIC messages appear, make
sure the StabiliTrak ®
system has not been turned
off using the StabiliTrak ®
on/off button. Then turn the
steering wheel clockwise from the nine o’clock position
to the three o’clock position. If this clears the
message(s), your vehicle does not need servicing. If this
does not clear the message(s), then turn the vehicle
off, wait 15 seconds, and then turn it back on again to
reset the system. If any of these messages still appear
on the Driver Information Center (DIC), your vehicle
should be taken in for service. For more information on
the DIC messages, see Driver Information Center (DIC)
on page 3-48 .

Driving in Water
{ CAUTION: Driving through rushing water can be
dangerous. Deep water can sweep your
vehicle downstream and you and your
passengers could drown. If it is only shallow
water, it can still wash away the ground from
under your tires, and you could lose traction
and roll the vehicle over. Do not drive through
rushing water.
Heavy rain can mean ash ooding, and ood waters
demand extreme caution.
Find out how deep the water is before you drive through
it. If it is deep enough to cover the wheel hubs, axles,
or exhaust pipe, do not try it — you probably will not get
through. Also, water that deep can damage the axle
and other vehicle parts. If the water is not too deep, drive slowly through it. At
faster speeds, water splashes on the ignition system
and your vehicle can stall. Stalling can also occur if
you get the tailpipe under water. And, as long as
the tailpipe is under water, you will never be able to
start the engine. When you go through water, remember
that when the brakes get wet, it may take you longer
to stop.
See Driving in Rain and on Wet Roads on page 4-27
for more information on driving through water.
After Off-Road Driving Remove any brush or debris that has collected on
the underbody, chassis, or under the hood. These
accumulations can be a re hazard.
After operation in mud or sand, have the brake linings
cleaned and checked. These substances can cause
glazing and uneven braking. Check the body structure,
steering, suspension, wheels, tires, and exhaust
system for damage. Also, check the fuel lines and
cooling system for any leakage.
Your vehicle will require more frequent service due to
off-road use. Refer to the Maintenance Schedule
for additional information.
4-25
Using heavier suspension components to get
added durability might not change your weight
ratings. Ask your dealer to help you load
your vehicle the right way.
If you put things inside your vehicle — like
suitcases, tools, packages, or anything else — they
will go as fast as the vehicle goes. If you have to
stop or turn quickly, or if there is a crash, they will
keep going.
{ CAUTION:Things you put inside your vehicle can
strike and injure people in a sudden stop
or turn, or in a crash.
Put things in the cargo area of your
vehicle. Try to spread the weight
evenly.
Never stack heavier things, like
suitcases, inside the vehicle so that
some of them are above the tops of
the seats.
CAUTION: (Continued) CAUTION: (Continued)
Do not leave an unsecured child
restraint in your vehicle.
When you carry something inside the
vehicle, secure it whenever you can.
Do not leave a seat folded down
unless you need to.
There is also important loading information for
off-road driving in this manual. See “Loading Your
Vehicle for Off-Road Driving” under Off-Road
Driving on page 4-12 .
Add-On Equipment When you carry removable items, you may need to put
a limit on how many people you can carry inside
your vehicle. Be sure to weigh your vehicle before you
buy and install the new equipment.
Notice: Overloading your vehicle may cause
damage. Repairs would not be covered by your
warranty. Do not overload your vehicle.
Remember not to exceed the Gross Axle Weight
Rating (GAWR) of the front or rear axle.

Automatic Level Control
The automatic level control rear suspension
comes as a part of the Road Sensing Suspension.
See Road Sensing Suspension on page 4-6 .
This type of level control is fully automatic and will
provide a better leveled riding position as well
as better handling under a variety of passenger
and loading conditions. An air compressor
connected to the rear shocks will raise or lower
the rear of the vehicle to maintain proper vehicle
height. The system is activated when the
ignition key is turned to RUN and will automatically
adjust vehicle height thereafter. The system
may exhaust (lower vehicle height) for up to
10 minutes after the ignition key has been turned
to LOCK. You may hear the air compressor
operating when the height is being adjusted. If a weight-distributing hitch is being used, it is
recommended to allow the shocks to in ate,
thereby leveling the vehicle prior to adjusting the
height. See “Weight distributing Hitches and
Weight Carrying Hitches” under Towing a Trailer
on page 4-44 .
Towing Towing Your Vehicle Consult your dealer/retailer or a professional towing
service if you need to have your disabled vehicle towed.
See Roadside Service on page 7-6 .
If you want to tow your vehicle behind another vehicle
for recreational purposes (such as behind a motorhome),
see Recreational Vehicle Towing following.
4-41
Used Replacement Wheels
{ CAUTION: Putting a used wheel on your vehicle is
dangerous. You cannot know how it has been
used or how far it has been driven. It could fail
suddenly and cause a crash. If you have to
replace a wheel, use a new GM original
equipment wheel. Tire Chains
{ CAUTION: Do not use tire chains. There is not enough
clearance. Tire chains used on a vehicle
without the proper amount of clearance can
cause damage to the brakes, suspension, or
other vehicle parts. The area damaged by the
tire chains could cause you to lose control of
your vehicle and you or others may be injured
in a crash. Use another type of traction device
only if its manufacturer recommends it for use
on your vehicle and tire size combination and
road conditions. Follow that manufacturer’s
instructions. To help avoid damage to your
vehicle, drive slowly, re-adjust or remove
the device if it is contacting your vehicle,
and do not spin your wheels. If you do nd
traction devices that will t, install them on
the rear tires.
