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 mopar.com/om (U.S.), owners.mopar.ca
(Canada) or your local Jeep® brand dealer.
DRIVING AND ALCOHOL
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 rideshare, a friend
or use public transportation.
WARNING
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: 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.

Prolonged driving with the MIL on could cause
further damage to the emission control
system. It could also affect fuel economy and
driveability. The vehicle must be serviced
before any emissions tests can be performed.

running, severe catalytic converter damage
and power loss will soon occur. Immediate
service is required.

Be possible that vehicle systems,
including safety related systems, could be
impaired or a loss of vehicle control could
occur that may result in an accident
involving serious injury or death.

WARNING!
Never place a rear-facing child restraint in
front of an air bag. A deploying passenger
front air bag can cause death or serious injury
to a child 12 years or younger, including a
child in a rear-facing child restraint.
Never install a rear-facing child restraint in the
front seat of a vehicle. Only use a rear-facing
child restraint in the rear seat. If the vehicle
does not have a rear seat, do not transport a
rear-facing child restraint in that vehicle.
WARNING!
The seat belt assembly must be replaced if the
switchable Automatic Locking Retractor (ALRyf
feature or any other seat belt function is not
working properly when checked according to
the procedures in the Service Manual.
Failure to replace the seat belt assembly
could increase the risk of injury in collisions.
Do not use the Automatic Locking Mode to
restrain occupants who are wearing the seat
belt or children who are using booster seats.
The locked mode is only used to install
rear-facing or forward-facing child restraints
that have a harness for restraining the child.
WARNING!
Do not place the seat belt webbing behind the
third row stow clip when using the seat belt to
restrain an occupant. The seat belt will not be
positioned properly on the occupant and they
could be more seriously injured in an accident
as a result.

If a child restraint system, child, small teen-
ager or adult in the front passenger seat is
seated improperly, the occupant may provide
an output signal to the OCS that is different
from the occupant’s properly seated weight
input. This may result in serious injury or death
in a collision.
Always wear your seat belt and sit properly,
with the seatback in an upright position, your
back against the seatback, sitting upright,
facing forward, in the center of the seat, with
your feet comfortably on or near the floor.
Do not carry or hold any objects (e.g., back -
packs, boxes, etc.yf Z K L O H V H D W H G L Q W K H I U R Q W
passenger seat. Holding an object may
provide an output signal to the OCS that is
different than the occupant’s properly seated
weight input, which may result in serious injury
or death in a collision.
Placing an object on the floor under the front
passenger seat may prevent the OCS from
working properly, which may result in serious
injury or death in a collision. Do not place any
objects on the floor under the front passenger
seat.
WARNING!
Unapproved modifications or service proce-
dures to the passenger seat assembly, its
related components, seat cover or cushion
may inadvertently change the air bag deploy -
ment in case of a frontal collision. This could
result in death or serious injury to the front
passenger if the vehicle is involved in a colli -
sion. A modified vehicle may not comply with
required Federal Motor Vehicle Safety Stan -
dards (FMVSSyf D Q G R U & D Q D G L D Q 0 R W R U
Vehicle Safety Standards (CMVSSyf .
If it is necessary to modify the air bag system
for persons with disabilities, contact an autho -
rized dealer.
