Cellular Phone Usage
Cellular phone usage may cause
interference with the vehicle's radio.
This interference may occur when
making or receiving phone calls,
charging the phone's battery,
or simply having the phone on. This
interference causes an increased
level of static while listening to the
radio. If static is received while
listening to the radio, unplug the
cellular phone and turn it off.
Rear Side Window
Antenna
The AM-FM antenna is located in
the passenger rear side windows.
Make sure the inside surfaces of the
rear side windows are not scratched
and that the lines on the glass are
not damaged. If the inside surfaces
are damaged, they could interfere
with radio reception.If a cellular telephone antenna
needs to be attached to the glass,
make sure that the grid lines for the
AM-FM antenna are not damaged.
There is enough space between
the grid lines to attach a cellular
telephone antenna without
interfering with radio reception.
Notice:
Using a razor blade or
sharp object to clear the inside
of the rear side windows may
affect radio reception or damage
the rear side window antenna.
Repairs would not be covered by
the warranty. Do not clear the
inside of the rear side windows
with sharp objects.
Notice: Do not apply aftermarket
glass tinting with metallic film.
The metallic film in some tinting
materials will interfere with or
distort the incoming radio
reception. Any damage caused to
the antenna due to metallic tinting
materials will not be covered by
the warranty.
Satellite Radio Antenna
The XM Satellite Radio antenna is
located on the roof of the vehicle.
Keep the antenna clear of
obstructions for clear radio
reception.
If the vehicle has a sunroof, the
performance of the XM system
(if equipped) may be affected if the
sunroof is open.

WARNING (Continued)
.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.
There are some important things to
remember about how to load your
vehicle.
.The heaviest things should be
on the floor, forward of the rear
axle. Put heavier items as far
forward as you can.
.Be sure the load is properly
secured, so things are not
tossed around. You will find other important
information under
Vehicle Load
Limits on page 9‑23 andTires on
page 10‑48.
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,
flowers, 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
fires (where permitted), camp
stoves, and lanterns.
.Never park your vehicle over
dry grass or other combustible
materials that could catch fire
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.

The length of time the heater should
remain plugged in depends on
several factors. Ask a dealer in the
area where you will be parking the
vehicle for the best advice on this.
Retained Accessory
Power (RAP)
The following vehicle accessories
can be used for up to 10 minutes
after the engine is turned off:
.Audio System
.Power Windows
.OnStar System (if equipped)
.Sunroof (if equipped)
These features work when the
key is in ON/RUN or ACC/
ACCESSORY. Once the key is
turned from ON/RUN to LOCK/OFF,
the windows and sunroof continue
to work up to 10 minutes until any
door is opened. The radio continues
to work for up to 10 minutes or until
the driver door is opened.
Shifting Into Park
{WARNING
It can be dangerous to get out of
the vehicle if the shift lever is not
fully in P (Park) with the parking
brake firmly set. The vehicle can
roll. If you have left the engine
running, the vehicle can move
suddenly. You or others could be
injured. To be sure the vehicle
will not move, even when you are
on fairly level ground, use the
steps that follow. If you have a
four-wheel drive transfer case
with a N (Neutral) position, and
the transfer case is in N (Neutral),
the vehicle will be free to roll,
even if the shift lever is in
P (Park). So, be sure the transfer
case is in a drive gear —not in
N (Neutral). If you are pulling a
(Continued)
WARNING (Continued)
trailer, seeDriving Characteristics
and Towing Tips on page 9‑75.
Always set the parking brake.
1. Hold the brake pedal down, then set the parking brake.
See Parking Brake on page 9‑51
for more information.
2. Move the shift lever into the P (Park) position by pulling the
shift lever toward you and
moving it up as far as it will go.
3. Be sure the transfer case is in a drive gear —not in N (Neutral).
4. Turn the ignition key to LOCK/OFF.
5. Remove the key and take it with you. If you can leave the vehicle
with the ignition key in your
hand, the vehicle is in P (Park).

This has the effect of reducing the
load on the front. However, the front
GAWR, rear GAWR, and the Gross
Vehicle Weight Rating (GVWR)
must never be exceeded.
{WARNING
On some vehicles that have
certain front mounted equipment,
such as a snow plow, it may be
possible to load the front axle to
the front gross axle weight rating
(GAWR) but not have enough
weight on the rear axle to have
proper braking performance. Ifthe brakes cannot work properly,
you could have a crash. To
help the brakes work properly
when a snow plow is installed,
always follow the snow plow
manufacturer or installer's
recommendation for rear ballast
to ensure a proper front and rear
weight distribution ratio, even
though the actual front weight
(Continued)
WARNING (Continued)
may be less than the front
GAWR, and the total vehicle
weight is less than the gross
vehicle weight rating (GVWR).
Maintaining a proper front and
rear weight distribution ratio is
necessary to provide proper
braking performance.
Total vehicle reserve capacity is
the difference between the GVWR
and the weight of the vehicle with
full fuel and passengers. It is the
amount of weight that can be added
to the vehicle before reaching
theGVWR. Keep in mind that
reserve capacity numbers are
intended as a guide when selecting
the amount of equipment or cargo
the vehicle can carry. If you are
unsure of the vehicle's front, rear,
or total weight, go to a weigh station
and weigh the vehicle. Your dealer
can also help you with this. The total vehicle reserve capacity
for the vehicle can be found
in the lower right corner of the
Certification/Tire label as shown
previously.
See your dealer for additional
advice and information about using
a snow plow on the vehicle. Also,
see
Vehicle Load Limits on
page 9‑23.
Emergency Roof Lamp
Provisions
Vehicles with the RPO VYU snow
plow prep package also have an
emergency roof lamp provision
package, RPO TRW. Wiring for the
emergency roof lamp is provided
above the overhead console. See
Auxiliary Roof-Mounted Lamp on
page 6‑6 for switch location.
