Care of Your CD and DVD Player
The use of CD lens cleaner discs is not advised, due to
the risk of contaminating the lens of the CD optics
with lubricants internal to the CD mechanism.
Cleaning the Video Screen
Pour some isopropyl or rubbing alcohol on a clean cloth
and gently wipe the video screen. Do not spray
directly onto the screen and do not press too hard or
too long on the video screen.
Fixed Mast Antenna
The ®xed mast antenna can withstand most car washes
without being damaged. If the mast should ever
become slightly bent, you can straighten it out by hand.
If the mast is badly bent, as it might be by vandals,
you should replace it.
Check occasionally to be sure the mast is still tightened
to the cowl. If tightening is required, tighten by hand,
then with a wrench one quarter turn.
XMŸ Satellite Radio Antenna
System (48 Contiguous US States)
Your XMŸ 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 your XMŸ system may be affected
if your sunroof is open.
Loading items onto the roof of your vehicle can interfere
with the performance of your XMŸ system. Make
sure that the XMŸ satellite antenna is not obstructed.
Chime Level Adjustment
The radio is the vehicle 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 be displayed on the radio. 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 be displayed. Each time the
chime volume is changed, three chimes will sound as an
example of the new volume selected. Removing the radio
and not replacing it with a factory radio or chime module
will disable vehicle chimes.

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 doesn't 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'll ®nd other important information in this manual.
