WARNING!
ALWAYS obey traffic laws and pay attention to
the road. ALWAYS drive safely with your hands on
the steering wheel. You have full responsibility
and assume all risks related to the use of the
features and applications in this vehicle. Only
use the features and applications when it is safe
to do so. Failure to do so may result in an
accident involving serious injury or death.
CAUTION!
To avoid damage to the mirror during cleaning,
never spray any cleaning solution directly onto
the mirror. Apply the solution onto a clean cloth
and wipe the mirror clean.
WARNING!
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.

WARNING!
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
jack. If you need to get under a raised vehicle,
take it to a service center where it can be
raised on a lift.
WARNING!

WARNING!
Do not connect the jumper cable to the negative
(-yf post of the discharged battery. The resulting
electrical spark could cause the battery to
explode and could result in personal injury.
CAUTION!
Do not run the booster vehicle engine above
2,000 RPM since it provides no charging benefit,
wastes fuel, and can damage booster vehicle
engine.
CAUTION!
Accessories plugged into the vehicle power
outlets draw power from the vehicle’s battery,
even when not in use (i.e., cellular devices, etc.yf
Eventually, if plugged in long enough without
engine operation, the vehicle’s battery will
discharge sufficiently to degrade battery life
and/or prevent the engine from starting.

Never have any smoking materials lit in or
near the vehicle when the fuel door is open or
the tank is being filled.

This is in violation of most state and federal
fire regulations and may cause the Malfunc-
tion Indicator Light to turn on.
A fire may result if fuel is pumped into a
portable container that is inside of a vehicle.
You could be burned. Always place fuel
containers on the ground while filling.

Racing the engine or spinning the wheels may
lead to transmission overheating and failure.
Allow the engine to idle with the transmission
in NEUTRAL for at least one minute after every
five rocking-motion cycles. This will minimize
overheating and reduce the risk of transmis-
sion failure during prolonged efforts to free a
stuck vehicle.

Exhaust gases can injure or kill. They contain
Carbon Monoxide (COyfZKLFKLVFRORUOHVVDQG
odorless. Breathing it can make you uncon-
scious and can eventually poison you.
To avoid breathing CO Ú page 300.
A hot exhaust system can start a fire if you
park over materials that can burn. Such mate -
rials might be grass or leaves coming into
contact with your exhaust system. Do not park
or operate your vehicle in areas where your
exhaust system can contact anything that can
burn.
CAUTION!
The catalytic converter requires the use of
unleaded fuel only. Leaded gasoline will
destroy the effectiveness of the catalyst as an
emissions control device and may seriously
reduce engine performance and cause
serious damage to the engine.

You or others can be badly burned by hot
engine coolant (antifreezeyfRUVWHDPIURP\RXU
radiator. If you see or hear steam coming from
under the hood, do not open the hood until the
radiator has had time to cool. Never open a
cooling system pressure cap when the radi-
ator or coolant bottle is hot.
Keep hands, tools, clothing, and jewelry away
from the radiator cooling fan when the hood is
raised. The fan starts automatically and may
start at any time, whether the engine is
running or not.

Do not use a pressure cap other than the one
specified for your vehicle. Personal injury or
engine damage may result.

When replacing a blown fuse, always use an
appropriate replacement fuse with the same
amp rating as the original fuse. Never replace
a fuse with another fuse of higher amp rating.
The use of a fuse with a rating other than indi-
cated may result in a dangerous electrical
system overload. If a properly rated fuse
continues to blow, it indicates a problem in the
circuit that must be corrected. Never replace a
blown fuse with metal wires or any other mate -
rial. Do not place a fuse inside a circuit
breaker cavity or vice versa. Failure to use
proper fuses may result in serious personal
injury, fire and/or property damage.
Before replacing a fuse, make sure that the
ignition is off and that all the other services
are switched off and/or disengaged.
If the replaced fuse blows again, contact an
authorized dealer.

If it is necessary to wash the engine
compartment, take care not to directly hit the
fuse box, and the windshield wiper motors with
water.
CAUTION!
When installing the power distribution center
cover, it is important to ensure the cover is
properly positioned and fully latched. Failure to
do so may allow water to get into the power
distribution center and possibly result in an
electrical system failure.8

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

Not all features shown in this manual may apply to your vehicle. For additional information, visit mopar.com/om (U.S.), owners.mopar.ca

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.
