If you have any questions about the operation of
the navigation system or the update process, contact
the GM Nav Disc Center toll-free phone number,
1-877-NAV-DISC (1-877-628-3472) or go to the center’s
website, gmnavdisc.com. If you need any updates or
a replacement disc, because the current disc is lost,
damaged, or needs to be updated, call the GM Nav
Disc Center or order a new disc online. To order a disc,
have your Vehicle Identication Number (VIN) available.
This helps the center make sure you receive the correct
and most up-to-date DVD map disc for your vehicle.
See “Vehicle Identication Number (VIN)” in the Index
of your vehicle’s owner manual for more information.
After receiving the updated disc, replace the old disc
in the navigation system. See “Installing the DVD Map
Disc” and “Ejecting the DVD Map Disc” under Maps
on page 4-15 . Dispose of the old disc to avoid confusion
about which disc is the most current.
Database Coverage Explanations Coverage area depends upon the map detail available.
Some areas have greater map detail than others. The
navigation system works only as well as the information
provided on the map disc. See Ordering Map DVDs on
page 4-61 on how to obtain updated map information. Navigation Audio System Notice: Before adding any sound equipment to
the vehicle, such as an audio system, CD player,
CB radio, mobile telephone, or two-way radio, make
sure that it can be added by checking with your
dealer/retailer. Also, check federal rules covering
mobile radio and telephone units. If sound equipment
can be added, it is very important to do it properly.
Added sound equipment can interfere with the
operation of the vehicle’s engine, radio, or other
systems, and even damage them. The vehicle’s
systems can interfere with the operation of sound
equipment that has been added.
Notice: The chime signals related to safety belts,
parking brake, and other functions of the vehicle
operate through the navigation system. If that
equipment is replaced or additional equipment is
added to the vehicle, the chimes may not work.
Make sure that replacement or additional equipment
is compatible with the vehicle before installing it.
See “Accessories and Modications” in the Index
of the vehicle’s owner manual.

Antilock Brake System (ABS) This vehicle has the Antilock Brake System (ABS), an
advanced electronic braking system that helps prevent a
braking skid.
When the engine is started and the vehicle begins to
drive away, ABS checks itself. A momentary motor or
clicking noise might be heard while this test is going on.
This is normal.
If there is a problem with
ABS, this warning light
stays on. See Antilock
Brake System (ABS)
Warning Light on
page 3-40 .
Along with ABS, the vehicle has a Dynamic Rear
Proportioning (DRP) system. If there is a DRP problem,
both the brake and ABS warning lights 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/retailer
for service. Let us say the road is wet and you are driving safely.
Suddenly, an animal jumps out in front of you. You slam
on the brakes and continue braking. Here is what
happens with ABS:
A computer senses that the wheels are slowing down.
If one of the wheels is about to stop rolling, the computer
will separately work the brakes at each front wheel
and at both rear wheels.
ABS can change the brake pressure to each wheel, as
required, faster than any driver could. This can help
the driver steer around the obstacle while braking hard.
As the brakes are applied, the computer keeps receiving
updates on wheel speed and controls braking pressure
accordingly.
Remember: ABS does not change the time needed to get
a foot up to the brake pedal or always decrease stopping
distance. If you get too close to the vehicle in front of you,
there will not be enough time to apply the brakes if that
vehicle suddenly slows or stops. Always leave enough
room up ahead to stop, even with ABS.
Using ABS Do not pump the brakes. Just hold the brake pedal
down rmly and let antilock work. The brakes might
vibrate or some noise might be heard, but this is normal.

Magnetic Ride Control™ The vehicle may have the MagneRide control system.
MagneRide constantly checks speed, wheel position,
lift/dive and steering of the vehicle. The damping force for
each shock absorber and adjustment level is chosen for
the best ride and handling.
MagneRide also works with the tow/haul switch that,
when engaged, will provide more rmness from the shock
absorbers. This added control gives better ride and
handling when carrying heavy loads or towing a trailer.
See Tow/Haul Mode on page 2-33 for more information.
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 5-44 .
Locking Rear Axle Vehicles with a locking rear axle can give more traction
on snow, mud, ice, sand or gravel. It works like a
standard axle most of the time, but when traction is
low, this feature will allow the rear wheel with the
most traction to move the vehicle.
All-Wheel Drive (AWD) System If the vehicle has this feature, engine power is sent to all
four wheels when extra traction is needed. This is like
four-wheel drive, but there is no separate lever or switch
to engage or disengage the front axle. It is fully automatic,
and adjusts itself as needed for road conditions.
If the vehicle is a Two-mode Hybrid, see “Four-Wheel
Drive” in the Two-mode Hybrid Supplement.

Before You Go Off-Roading Have all necessary maintenance and service
work done.
Make sure there is enough fuel, that uid levels are
where they should be, and that the spare tire, if the
vehicle has one, is fully inated.
Be sure to read all the information about
all-wheel-drive vehicles in this manual.
Make sure all underbody shields, if the vehicle has
them, are properly attached.
Know the local laws that apply to off-roading where
you will be driving or check with law enforcement
people in the area.
Be sure to get the necessary permission if you will
be on private land. If you think you will need some more ground clearance at
the front of your vehicle, you can remove the front fascia
lower air dam. The air dam is held in place by two bolts
and 10 snaps accessible from underneath the front
fascia.
To remove the air dam:
1. Remove the two outboard air dam bolts.
2. With a at-blade tool, disengage the snaps.
3. After the bolts are removed and the snaps are
disengaged, push forward on the air dam until it
is free.
Notice: Operating your vehicle for extended
periods without the front fascia lower air dam
installed can cause improper air ow to the engine.
Always be sure to replace the front fascia air
dam when you are nished off-road driving.
After off-roading, be sure to reinstall the air dam:
1. Line up the snaps and push the air dam rearward
to engage the snaps.
2. Install the two outboard bolts.

Environmental Concerns Off-road driving can provide wholesome and satisfying
recreation. However, it also raises environmental
concerns. We recognize these concerns and urge every
off-roader to follow these basic rules for protecting
the environment:
Always use established trails, roads, and areas that
have been specially set aside for public off-road
recreational driving and obey all posted regulations.
Avoid any driving practice that could damage
shrubs, owers, trees, or grasses or disturb wildlife.
This includes wheel-spinning, breaking down
trees, or unnecessary driving through streams
or over soft ground.
Always carry a litter bag and make sure all refuse is
removed from any campsite before leaving.
Take extreme care with open res (where
permitted), camp stoves, and lanterns.
Never park your vehicle over dry grass or other
combustible materials that could catch re from
the heat of the vehicle’s exhaust system. Traveling to Remote Areas It makes sense to plan your trip, especially when going to
a remote area. Know the terrain and plan your route. Get
accurate maps of trails and terrain. Check to see if there
are any blocked or closed roads.
It is also a good idea to travel with at least one other
vehicle in case something happens to one of them.
For vehicles with a winch, be sure to read the winch
instructions. In a remote area, a winch can be handy if
you get stuck but you will want to know how to use
it properly.
Getting Familiar with Off-Road Driving It is a good idea to practice in an area that is safe
and close to home before you go into the wilderness.
Off-roading requires some new and different skills.
Tune your senses to different kinds of signals. Your eyes
need to constantly sweep the terrain for unexpected
obstacles. Your ears need to listen for unusual tire
or engine sounds. Use your arms, hands, feet, and
body to respond to vibrations and vehicle bounce.
