INTRODUCTION
This manual has been prepared with the assistance of
service and engineering specialists to acquaint you with
the operation and maintenance of your new vehicle. It is
supplemented by a Warranty Information Booklet and
various customer oriented documents. You are urged to
read these publications carefully. Following the instruc-
tions and recommendations in this manual will help
assure safe and enjoyable operation of your vehicle.
NOTE: After you read the manual, it should be stored
in the vehicle for convenient reference and remain with
the vehicle when sold, so that the new owner will be
aware of all safety warnings.
When it comes to service, remember that your dealer
knows your vehicle best, has the factory-trained techni-
cians and genuine Mopartparts, and is interested in
your satisfaction.
ROLLOVER WARNING
Utility vehicles have a significantly higher rollover rate
than other types of vehicles. This vehicle has a higher
ground clearance, and a higher center of gravity than
many passenger cars. Driven in an unsafe manner, all
vehicles can be caused to go out of control. Because of the
higher center of gravity, if this vehicle is out of control it
may rollover when some other vehicles may not.
Do not attempt sharp turns or abrupt maneuvers or other
unsafe driving actions that can cause loss of vehicle
control. Failure to operate this vehicle safely may result
in an accident, rollover of the vehicle, and severe or fatal
injury. Drive carefully.

Maintaining Your Airbag System
WARNING!
²Modifications to any part of the airbag system
could cause it to fail when you need it. You could
be injured if the airbag system is not there to
protect you. Do not modify the components or
wiring, including adding any kind of badges or
stickers to the steering wheel hub trim cover or
the upper right side of the instrument panel. Do
not modify the front bumper or vehicle body
structure.
²You need proper knee impact protection in a
collision. Do not mount or locate any aftermarket
equipment on or behind the knee bolsters.
²It is dangerous to try to repair any part of the
airbag system yourself. Be sure to tell anyone
who works on your vehicle that it has an airbag
system.
NOTE:Perchlorate Material ± special handling may apply,
See www.dtsc.ca.gov/hazardouswaste/perchlorate
Airbag Warning Light
You will want to have the airbag system ready to inflate
for your protection in an impact. The airbag system is
designed to be maintenance free. If any of the following
occurs, have an authorized dealer service the system
promptly:
²The light does not come on during the 6 to 8 seconds
after the ignition switch is first turned on.

Sunshade Operation
The sunshade can be opened manually. However, the
sunshade will open automatically as the sunroof opens.
NOTE:The sunshade cannot be closed if the sunroof is
open.
Wind Buffeting
Wind buffeting can be described as the perception of
pressure on the ears or a helicopter type sound in the
ears. Your vehicle may exhibit wind buffeting with the
windows down, or the sunroof (if equipped) in certain
open or partially open positions. This is a normal occur-
rence and can be minimized. If the buffeting occurs with
the rear windows open, open the front and rear windows
together to minimize the buffeting. If the buffeting occurs
with the sunroof open, adjust the sunroof opening to
minimize the buffeting or open any window.
Sunroof Maintenance
Use only a non-abrasive cleaner and a soft cloth to clean
the glass panel.
Ignition Off Operation
The power sunroof switches remain active for 10 minutes
after the ignition switch has been turned off. Opening
either front door will cancel this feature.
Sunroof Fully Closed
Press the switch forward and release to ensure that the
sunroof is fully closed.

12. Tire Pressure Monitoring Telltale Light
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If your vehicle
has tires of a different size than the size indicated on the
vehicle placard or tire inflation pressure label, you should
determine the proper tire inflation pressure for those
tires.)
As an added safety feature, your vehicle has been
equipped with a tire pressure monitoring system (TPMS)
that illuminates a low tire pressure telltale when one or
more of your tires are significantly under-inflated. Ac-
cordingly, when the low tire pressure telltale illuminates,
you should stop and check your tires as soon as possible,
and inflate them to the proper pressure. Driving on a
significantly under-inflated tire causes the tire to over-
heat and can lead to tire failure. Under-inflation alsoreduces fuel efficiency and tire tread life, and may affect
the vehicle's handling and stopping ability.
Please note that the TPMS is not a substitute for proper
tire maintenance, and it is the driver 's responsibility to
maintain correct tire pressure, even if under-inflation has
not reached the level to trigger illumination of the TPMS
low tire pressure telltale.
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the system is not
operating properly. The TPMS malfunction indicator is
combined with the low tire pressure telltale. When the
system detects a malfunction, the telltale will flash for
approximately one minute and then remain continuously
illuminated. This sequence will continue upon subse-
quent vehicle start-ups as long as the malfunction exists.
When the malfunction indicator is illuminated, the sys-
tem may not be able to detect or signal low tire pressure
as intended. TPMS malfunctions may occur for a variety

second track, three times, it will play the third, etc.
The center button on the left side rocker switch has no
function for a single disc CD player. However, when a
multiple disc CD player is equipped on the vehicle, the
center button will select the next available CD in the
player.
CD/DVD DISC MAINTENANCE
To keep the CD/DVD discs in good condition, take the
following precautions:
1. Handle the disc by its edge; avoid touching the
surface.
2. If the disc is stained, clean the surface with a soft cloth,
wiping from center to edge.
3. Do not apply paper, paper CD labels, or tape to the
disc; avoid scratching the disc.
