2-5Your vehicle has one
double
- sided key for the
ignition and all door locks
as well as the spare tire
hoist lock. Your vehicle also has a key
that locks and unlocks the
console storage area only.
If you ever lose your keys, your dealer will be able to
assist you with obtaining replacements.
In an emergency contact roadside assistance.
See ªRoadside Assistanceº in the Index for
more information.
If you ever lock your keys in your vehicle, you may
be able to have your doors unlocked automatically with
the OnStar system if you have an active OnStar

subscription. For more information see ªOnStarº
in the Index.

4-15Before You Go Off-Roading There are some things to do before you go out. For
example, be sure to have all necessary maintenance and
service work done. Check to make sure all underbody
shields (if so equipped) are properly attached. Is there
enough fuel? Is the spare tire fully inflated? Are the
fluid levels up where they should be? What are the local
laws that apply to off
- roading where you'll be driving?
If you don't know, you should check with law
enforcement people in the area. Will you be on
someone's private land? If so, be sure to get the
necessary permission.
Loading Your Vehicle for Off-Road Driving There are some important things to remember about
how to load your vehicle.

The heaviest things should be on the load floor and
forward of your rear axle. Put heavier items as far
forward as you can.

Be sure the load is secured properly, so driving on
the off
- road terrain doesn't toss things around. CAUTION:
Cargo on the load floor piled higher than
the seatbacks can be thrown forward
during a sudden stop. You or your
passengers could be injured. Keep cargo
below the top of the seatbacks.

Unsecured cargo on the load floor can
be tossed about when driving over rough
terrain. You or your passengers can be
struck by flying objects. Secure the
cargo properly.

Heavy loads on the roof raise the vehicle's
center of gravity, making it more likely to
roll over. You can be seriously or fatally
injured if the vehicle rolls over. Put heavy
loads inside the cargo area, not on the roof.
Keep cargo in the cargo area as far forward
and low as possible.
You'll find other important information in this manual.

Jack Positions (overall view)
These locations are the general area of jack
placement. See text and art following for the exact
jack placement. CAUTION: Getting under a vehicle when it is jacked up is
dangerous. If the vehicle slips off the jack, you
could be badly injured or killed. Never get under
a vehicle when it is supported only by a jack.
CAUTION: Raising your vehicle with the jack improperly
positioned can damage the vehicle and even
make the vehicle fall. To help avoid personal
injury and vehicle damage, be sure to fit the jack
lift head into the proper location before raising
the vehicle.
