Luggage Carrier
{CAUTION:
If you try to carry something on top of your
vehicle that is longer or wider than the luggage
carrier — like paneling, plywood, a mattress
and so forth — the wind can catch it as you
drive along. This can cause you to lose
control. What you are carrying could be
violently torn off, and this could cause you or
other drivers to have a collision, and of course
damage your vehicle. You may be able to carry
something like this inside. But, never carry
something longer or wider than the luggage
carrier on top of your vehicle.
A luggage carrier allows you to load things on top of
your vehicle. The luggage carrier has side rails attached
to the roof, sliding crossrails (if equipped) and places
to use for tying things down. These let you load
some other things on top of your vehicle, as long as
they are not wider or longer than the luggage carrier.
2-44

Sunroof
Your vehicle may be equipped with a power sliding
sunroof. To open or close your sunroof, the ignition must
be on or Retained Accessory Power (RAP) must be
active.
Press and release the back of the button in the overhead
console to open the sunroof. Press the front of the
button to close the sunroof. Once the sunroof is closed,
press the forward side of the button to open the
sunroof to the vent position.
The sunroof is also equipped with a sunshade which
you can pull forward to block sun rays.
Vehicle Personalization
Memory Seat
Your vehicle may have this
feature. The controls are
located on the driver’s
door, and are used
to program and recall
memory settings for the
driver’s seating positions,
outside mirror positions
and adjustable pedals
(if equipped).
Adjust the driver’s seat, including the seatback recliner
and lumbar, both of the outside mirrors, and the
adjustable pedals to the desired position. Then press
and hold button 1 (for driver 1) for three seconds.
A double chime will sound to let you know that the
position has been stored.
2-50

Fixed Mast Antenna
The xed mast antenna can withstand most car washes
without being damaged. If the mast should ever
become slightly bent, straighten it out by hand. If the
mast is badly bent, replace it.
Check occasionally to make sure the mast is still
tightened to the fender. If tightening is required, tighten
by hand, then with a wrench one quarter turn.
XM™ Satellite Radio Antenna
System
The XM™ Satellite Radio antenna is located on the roof
of your vehicle. Keep this antenna clear of snow and
ice build up for clear radio reception.
The performance of the XM™ system may be affected if
the sunroof is open.
Loading items onto the roof of your vehicle can interfere
with the performance of the XM™ system. Make sure
that the XM™ satellite antenna is not obstructed.
Chime Level Adjustment
The radio is the vehicle’s chime producer. To change
the volume level, press and hold pushbutton 6 with
the ignition on and the radio power off. The chime
volume level will change from the normal level to loud,
and LOUD will appear on the radio display. To
change back to the default or normal setting, press and
hold pushbutton 6 again. The chime level will change
from the loud level to normal, and NORMAL will appear
on the radio display. Removing the radio and not
replacing it with a factory radio or chime will disable
vehicle chimes.

Before 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.
Be sure you read all the information about your
four-wheel-drive vehicle in this manual.
Is there enough fuel? Is the spare tire fully inated? Are
the uid levels up where they should be? What are
the local laws that apply to off-roading where you will be
driving? If you do not 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 oor 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 does not toss things around.
{CAUTION:
Cargo on the load oor 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 oor can be
tossed about when driving over rough
terrain. You or your passengers can be
struck by ying 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 will nd other important information in this manual.
