NOTE: Failure to fold the fabric rearward will allow the
material to sag and may block the rearview mirror. FOLDING WINDSHIELD
The fold-down windshield and removable side bars on
your vehicle are structural elements that can provide
some protection in some accidents. The windshield also
provides some protection against weather, road debris
and intrusion of small branches and other objects.
Do not drive your vehicle on-road with the windshield
down and the side bars removed as you lose the protec-
tion these structural elements can provide.
If required for certain off-road uses, the side bars can be
removed and the windshield folded down. However, the
protection afforded by these features is then lost. If you
remove the side bars and fold down the windshield,
drive slowly and cautiously. It is recommended that the
speed of the vehicle be limited to 10 mph (16 km/h), with
low range operation preferred if you are driving off-road
with the windshield folded down.286 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

Raise the windshield and reinstall the side bars as soon as
the task that required their removal is completed and
before you return to on-road driving. Both you and your
passenger should wear seat belts at all times, on-road and
off-road, regardless of whether the windshield is raised
or folded down.
Outside rearview mirrors are mounted on the doors. If you
choose to remove the doors, see your authorized dealer for
a replacement cowl-mounted outside mirror. Federal law
requires outside mirrors on vehicles for on-road use.
WARNING!Carefully follow these warnings to help protect
against personal injury:
• Do not drive your vehicle on-road with the wind-
shield down. (Continued) WARNING! (Continued)• Do not drive your vehicle unless the windshield is
securely fastened, either up or down.
• Eye protection, such as goggles, should be worn at
all times when the windshield is down.
• Be sure that you carefully follow the instructions
for raising the windshield. Make sure that the
folding windshield, windshield wipers, side bars,
and all associated hardware and fasteners are cor-
rectly and tightly assembled before driving your
vehicle. Failure to follow these instructions may
prevent your vehicle from providing you and your
passengers protection in some accidents.
• If you remove the doors, store them outside the
vehicle. In the event of an accident, a loose door
may cause personal injury. 3 UNDERSTANDING THE FEATURES OF YOUR VEHICLE 287

WARNING!You or others could be injured if you carry the side
bars loose in your vehicle. Remove the side bars from
the vehicle or securely store them as described or
they may cause personal injury if an accident occurs.
See your authorized dealer for the cinch straps.
10. Remove the windshield wiper arms by first pulling
the wiper away from the windshield and out to the
“lock” position. Unsnap the wiper arm nut caps, and
remove the retaining nuts. Lift the wiper arms off and
store them in the center console or securely behind
the rear seat.
NOTE: It may be necessary to use a battery terminal
puller tool in order to separate the wiper arms from the
shaft after the nuts have been removed. 11. Remove the lower windshield plates by removing the
six black round-headed Torx  head screws (using a
#40 Torx  head driver) on each side of the base of the
windshield.290 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

12. Lower the windshield gently until it contacts the
rubber hood bumpers.

the strap to secure the windshield in place.
Raising The Windshield And Replacing Side Bars
1. Raise the windshield.
2. Loosely attach the rear of the side bar to the sport bar.

sound, until the engine is allowed to cool or the 4 minutes
duration is expired, whichever come first.
17. Vehicle Security Light — If Equipped
This light will flash at a fast rate for approxi-
mately 15 seconds, when the vehicle security
alarm is arming, and then will flash slowly
until the vehicle is disarmed.
18. Temperature Gauge
The temperature gauge shows engine coolant tempera-
ture. Any reading within the normal range indicates that
the engine cooling system is operating satisfactorily.
The gauge pointer will likely indicate a higher tempera-
ture when driving in hot weather, up mountain grades,
or when towing a trailer. It should not be allowed to
exceed the upper limits of the normal operating range. CAUTION!Driving with a hot engine cooling system could
damage your vehicle. If the temperature gauge reads
“H” pull over and stop the vehicle. Idle the vehicle
with the air conditioner turned off until the pointer
drops back into the normal range. If the pointer
remains on the “H” and you hear continuous chimes,
turn the engine off immediately and call an autho-
rized dealer for service.
WARNING!A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call an authorized dealer
for service if your vehicle overheats. If you decide to (Continued)

AUTOMATIC TRANSMISSION — IF EQUIPPED
CAUTION!Damage to the transmission may occur if the follow-
ing precautions are not observed:
• Shift into PARK only after the vehicle has come to
a complete stop.
• Shift into or out of REVERSE only after the vehicle
has come to a complete stop and the engine is at
idle speed.
• Do not shift between PARK, REVERSE, NEU-
TRAL, or DRIVE when the engine is above idle
speed.
• Before shifting into any gear, make sure your foot
is firmly pressing the brake pedal. NOTE: You must press and hold the brake pedal while
shifting out of PARK.
WARNING!• Unintended movement of a vehicle could injure
those in or near the vehicle. As with all vehicles,
you should never exit a vehicle while the engine is
running. Before exiting a vehicle, always apply the
parking brake, shift the transmission into PARK,
and remove the ignition key. Once the ignition key
is removed, the shift lever is locked in PARK,
securing the vehicle against unwanted movement.
• When leaving the vehicle, always remove the key
fob from the ignition key and lock your vehicle.
Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Allowing children to

WARNING!• Never use the PARK position as a substitute for the
parking brake. Always apply the parking brake
fully when parked to guard against vehicle move-
ment and possible injury or damage.
• Your vehicle could move and injure you and others
if it is not completely in PARK. Check by trying to
move the shift lever rearward (with the brake pedal
released), after you have placed it in PARK. Make
sure the transmission is in PARK before leaving
the vehicle.
• It is dangerous to move the shift lever out of PARK
or NEUTRAL if the engine speed is higher than
idle speed. If your foot is not firmly pressing the
brake pedal, the vehicle could accelerate quickly
forward or in reverse. You could lose control of the
vehicle and hit someone or something. Only shift (Continued) WARNING! (Continued)into gear when the engine is idling normally and

5. Restart the engine.
6. Shift into the desired gear range. If the problem is no
longer detected, the transmission will return to normal
operation.
NOTE: Even if the transmission can be reset, we recom-
mend that you visit your authorized dealer at your
earliest possible convenience. Your authorized dealer has
diagnostic equipment to determine if the problem could
recur. If the transmission cannot be reset, authorized
dealer service is required.
Electronic Range Select (ERS) Operation
The Electronic Range Select (ERS) shift control allows the
driver to limit the highest available gear when the shift
lever is in the DRIVE position. For example, if you shift the transmission into 3 (third gear), the transmission will
never shift above third gear, but will shift down into
second and first gear normally.
You can switch between DRIVE and ERS mode at any
vehicle speed. When the shift lever is in the DRIVE
position, the transmission will operate automatically, shift-
ing between all available gears. Tapping the shift lever to
the left (-) will downshift the transmission, activate ERS
mode, display the current gear in the instrument cluster,
and maintain that gear as the top available gear. Once in
ERS mode, tapping the shift lever to the left (-) or right (+)
will change the top available gear.
To exit ERS mode, simply press and hold the shift lever to
the right (+) until “D” is once again displayed in the shift
lever position indicator in the instrument cluster.426 STARTING AND OPERATING
