Essential Information
Consult the Table of Contents to determine
which section contains the information you
desire.
Since the specification of your vehicle
depends on the items of equipment ordered,
certain descriptions and illustrations may
differ from your vehicle's equipment.
The detailed Index at the back of this User
Guide contains a complete listing of all
subjects.
Symbols
Some vehicle components have colored
labels whose symbols indicate precautions to
be observed when using this component.
Refer to “Warning Lights and Messages” in
“Getting To Know Your Instrument Panel”
for further information on the symbols used
in your vehicle.
ROLLOVER WARNING
Utility vehicles have a significantly higher
rollover rate than other types of vehicles.
This vehicle has a higher ground clearanceand a higher center of gravity than many
passenger vehicles. It is capable of
performing better in a wide variety of off-road
applications. Driven in an unsafe manner, all
vehicles can go out of control. Because of the
higher center of gravity, if this vehicle is out
of control it may roll over when some other
vehicles may not.
Do not attempt sharp turns, abrupt maneu
-
vers, or other unsafe driving actions that can
cause loss of vehicle control. Failure to
operate this vehicle safely may result in a
collision, rollover of the vehicle, and severe
or fatal injury. Drive carefully.
Rollover Warning Label

Failure to use the driver and passenger seat
belts provided is a major cause of severe or
fatal injury. In a rollover crash, an unbelted person is significantly more likely to die than a
person wearing a seat belt. Always buckle up.

On models that are equipped with remote
start, the driver’s heated seat can be
programmed to come on during a remote
start.
This feature can be programmed through the
Uconnect system. Refer to “Uconnect
Settings” in “Multimedia” in the Owner’s
Manual for further information.
WARNING!
Adjusting a seat while driving may be
dangerous. Moving a seat while driving
could result in loss of control which
could cause a collision and serious injury
or death.
Seats should be adjusted before
fastening the seat belts and while the
vehicle is parked. Serious injury or death
could result from a poorly adjusted seat
belt.
Do not ride with the seatback reclined so
that the shoulder belt is no longer resting
against your chest. In a collision you
could slide under the seat belt, which
could result in serious injury or death.
WARNING!
Persons who are unable to feel pain to
the skin because of advanced age,
chronic illness, diabetes, spinal cord
injury, medication, alcohol use, exhaus-
tion or other physical condition must
exercise care when using the seat heater.
It may cause burns even at low tempera-
tures, especially if used for long periods
of time.
Do not place anything on the seat or
seatback that insulates against heat,
such as a blanket or cushion. This may
cause the seat heater to overheat. Sitting
in a seat that has been overheated could
cause serious burns due to the increased
surface temperature of the seat.
