The driver’s primary responsibility is the safe operation of the vehicle. Driving while distracted can result in loss of vehicle control,
resulting in an accident and personal injury. FCA US LLC strongly recommends that the driver use extreme caution when using
any device or feature that may take their attention off the road. Use of any electrical devices, such as cellular telephones,
computers, portable radios, vehicle navigation or other devices, by the driver while the vehicle is moving is dangerous and could
lead to a serious accident. Texting while driving is also dangerous and should never be done while the vehicle is moving. If you
find yourself unable to devote your full attention to vehicle operation, pull off the road to a safe location and stop your vehicle.
Some states or provinces prohibit the use of cellular telephones or texting while driving. It is always the driver’s responsibility to
comply with all local laws.
This Owner’s Manual has been prepared to help you get acquainted with your new Jeep® brand vehicle and to provide a
convenient reference source for common questions.
Not all features shown in this manual may apply to your vehicle. For additional information, visit www.mopar.com (U.S.),
www.mopar.ca (Canada) or your local Jeep® brand dealer.
WARNING: Operating, servicing and maintaining a passenger vehicle or off-highway
motor vehicle can expose you to chemicals including engine exhaust, carbon monoxide,
phthalates, and lead, which are known to the State of California to cause cancer and
birth defects or other reproductive harm. To minimize exposure, avoid breathing exhaust,
do not idle the engine except as necessary, service your vehicle in a well-ventilated area
and wear gloves or wash your hands frequently when servicing your vehicle. For more
information go to www.P65Warnings.ca.gov/passenger-vehicle.
Drunk driving is one of the most frequent causes of accidents. Your driving ability can
be seriously impaired with blood alcohol levels far below the legal minimum. If you are
drinking, don’t drive. Ride with a designated non-drinking driver, call a cab, a friend or
use public transportation.
DRIVING AND ALCOHOL
Driving after drinking can lead to an accident. Your perceptions are less sharp, your
reflexes are slower and your judgment is impaired when you have been drinking.
Never drink and then drive.

WARNING!
Exhaust gases can injure or kill. They contain
carbon monoxide (COyfZKLFKLVFRORUOHVVDQG
odorless. Breathing it can make you
unconscious and can eventually poison you. To
avoid breathing (COyfIROORZWKHVHVDIHW\WLSV:
Do not run the engine in a closed garage or
in confined areas any longer than needed
to move your vehicle in or out of the area.
If you are required to drive with the trunk/
liftgate/rear doors open, make sure that all
windows are closed and the climate control
BLOWER switch is set at high speed. DO

Carbon monoxide (COyfLQH[KDXVWJDVHVLV
deadly. Follow the precautions below to
prevent carbon monoxide poisoning:
Do not inhale exhaust gases. They contain
carbon monoxide, a colorless and odorless
gas, which can kill. Never run the engine in
a closed area, such as a garage, and never
sit in a parked vehicle with the engine
running for an extended period. If the
vehicle is stopped in an open area with the
engine running for more than a short
period, adjust the ventilation system to
force fresh, outside air into the vehicle.
Guard against carbon monoxide with
proper maintenance. Have the exhaust
system inspected every time the vehicle is
raised. Have any abnormal conditions
repaired promptly. Until repaired, drive with
all side windows fully open.

Do not attempt to change a tire on the side
of the vehicle close to moving traffic. Pull
far enough off the road to avoid the danger
of being hit when operating the jack or
changing the wheel.
Being under a jacked-up vehicle is
dangerous. The vehicle could slip off the
jack and fall on you. You could be crushed.
Never put any part of your body under a
vehicle that is on a jack. If you need to get
under a raised vehicle, take it to a service
center where it can be raised on a lift.
Never start or run the engine while the
vehicle is on a jack.
The jack is designed to be used as a tool for
changing tires only. The jack should not be
used to lift the vehicle for service purposes.
The vehicle should be jacked on a firm level
surface only. Avoid ice or slippery areas.
CAUTION!
Always lift or jack the vehicle from the correct
jacking points. Failure to follow this informa-
tion could cause damage to the vehicle or
underbody components.

the vehicle close to moving traffic. Pull far
enough off the road to avoid being hit when
operating the jack or changing the wheel.

Carefully follow these tire changing warnings
to help prevent personal injury or damage to
your vehicle:
Always park on a firm, level surface as far
from the edge of the roadway as possible
before raising the vehicle.
Turn on the Hazard Warning Flashers.
Apply the parking brake firmly and set the
transmission in PARK.
Block the wheel diagonally opposite the
wheel to be raised.
Never start or run the engine with the
vehicle on a jack.
Do not let anyone sit in the vehicle when it
is on a jack.
Do not get under the vehicle when it is on a

vehicle, take it to a service center where it
can be raised on a lift.
