Maintaining Your Air Bag System
WARNING!
•Modifications to any part of the air bag
system could cause it to fail when you
need it. You could be injured if the air bag
system is not there to protect you. Do not
modify the components or wiring, includ-
ing adding any kind of badges or stickers
to the steering wheel hub trim cover or the
upper right side of the instrument panel.
Do not modify the front bumper, vehicle
body structure, or add aftermarket side
steps or running boards.
• It is dangerous to try to repair any part of
the air bag system yourself. Be sure to
tell anyone who works on your vehicle
that it has an air bag system.
• Do not attempt to modify any part of your
air bag system. The air bag may inflate
accidentally or may not function prop-
erly if modifications are made. Take your
vehicle to an authorized dealer for any
air bag system service. If your seat, in-
cluding your trim cover and cushion,
needs to be serviced in any way (includ-

Transporting Pets
Air Bags deploying in the front seat could
harm your pet. An unrestrained pet will be
thrown about and possibly injured, or injure a
passenger during panic braking or in a colli-
sion.
Pets should be restrained in the rear seat in
pet harnesses or pet carriers that are secured
by seat belts.
SAFETY TIPS
Transporting Passengers
NEVER TRANSPORT PASSENGERS IN THE
CARGO AREA.
WARNING!
• Do not leave children or animals insideparked vehicles in hot weather. Interior
heat build-up may cause serious injury
or death.
• It is extremely dangerous to ride in a
cargo area, inside or outside of a vehicle.
In a collision, people riding in these
WARNING!
areas are more likely to be seriously
injured or killed.
• Do not allow people to ride in any area of
your vehicle that is not equipped with
seats and seat belts.
• Be sure everyone in your vehicle is in a
seat and using a seat belt properly.
Exhaust Gas
WARNING!
Exhaust gases can injure or kill. They con-
tain carbon monoxide (CO), which is col-
orless and odorless. Breathing it can make
you unconscious and can eventually poi-
son you. To avoid breathing (CO), follow
these safety tips:
• Do not run the engine in a closed garageor 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
WARNING!
sure that all windows are closed and the
climate control BLOWER switch is set at
high speed. DO NOT use the recircula-
tion mode.
• If it is necessary to sit in a parked
vehicle with the engine running, adjust
your heating or cooling controls to force
outside air into the vehicle. Set the
blower at high speed.
The best protection against carbon monoxide
entry into the vehicle body is a properly
maintained engine exhaust system.
Whenever a change is noticed in the sound of
the exhaust system, when exhaust fumes can
be detected inside the vehicle, or when the
underside or rear of the vehicle is damaged,
have a competent mechanic inspect the com-
plete exhaust system and adjacent body areas
for broken, damaged, deteriorated, or misposi-
tioned parts. Open seams or loose connections
could permit exhaust fumes to seep into the
passenger compartment. In addition, inspect
the exhaust system each time the vehicle is
raised for lubrication or oil change. Replace as
required.

WARNING!
• ONLY use the driver’s side floor mat onthe driver’s side floor area. To check for
interference, with the vehicle properly
parked with the engine off, fully depress
the accelerator, the brake, and the
clutch pedal (if present) to check for
interference. If your floor mat interferes
with the operation of any pedal, or is not
secure to the floor, remove the floor mat
from the vehicle and place the floor mat
in your trunk.
• ONLY use the passenger’s side floor mat
on the passenger’s side floor area.
• ALWAYS make sure objects cannot fall or
slide into the driver’s side floor area
when the vehicle is moving. Objects can
become trapped under accelerator,
brake, or clutch pedals and could cause
a loss of vehicle control.
•
NEVER place any objects under the floor
mat (e.g., towels, keys, etc.). These ob-
jects could change the position of the
floor mat and may cause interference with
the accelerator, brake, or clutch pedals.
WARNING!
•If the vehicle carpet has been removed
and re-installed, always properly attach
carpet to the floor and check the floor mat
fasteners are secure to the vehicle carpet.
Fully depress each pedal to check for
interference with the accelerator, brake,
or clutch pedals then re-install the floor
mats.
• It is recommended to only use mild soap
and water to clean your floor mats. After
cleaning, always check your floor mat
has been properly installed and is se-
cured to your vehicle using the floor mat
fasteners by lightly pulling mat.
Periodic Safety Checks You Should Make
Outside The Vehicle
Tires
Examine tires for excessive tread wear and
uneven wear patterns. Check for stones,
nails, glass, or other objects lodged in the
tread or sidewall. Inspect the tread for cuts
and cracks. Inspect sidewalls for cuts, cracks, and bulges. Check the wheel nuts for
tightness. Check the tires (including spare)
for proper cold inflation pressure.
Lights
Have someone observe the operation of brake
lights and exterior lights while you work the
controls. Check turn signal and high beam
indicator lights on the instrument panel.
Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check area under the vehicle after overnight
parking for fuel, coolant, oil, or other fluid
leaks. Also, if gasoline fumes are detected or
if fuel, or brake fluid leaks are suspected. The
cause should be located and corrected imme-
diately.

less ignition node is in “OFF” mode,
remove the key fob from the vehicle and
lock the vehicle.
• Never leave children alone in a vehicle,
or with access to an unlocked vehicle.
• Allowing children to be in a vehicle un-
attended is dangerous for a number of
reasons. A child or others could be seri-
ously or fatally injured. Children should
be warned not to touch the parking
brake, brake pedal or the gear selector.
• Do not leave the key fob in or near the
vehicle, or in a location accessible to
children, and do not leave the ignition of
a vehicle equipped with Keyless Enter-
WARNING!
N-Go in the ACC or ON/RUN mode. A
child could operate power windows,
other controls, or move the vehicle.
Start the engine with the gear selector in the
NEUTRAL or PARK position. Apply the brake
before shifting to any driving range.
Normal Starting — Gasoline Engine
NOTE:
Normal starting of either a cold or a warm
engine is obtained without pumping or push-
ing the accelerator pedal.
Place your foot on the brake and place the
ignition to the START mode and release when
the engine starts. If the engine fails to start
within 10 seconds:
1. Place the ignition in the OFF mode.
2. Wait 10 to 15 seconds.
3. Repeat the “Normal Starting” procedure.
Tip Start Feature
Place the ignition in the START mode and
release it as the starter engages. The starter
motor will automatically disengage itself
once engine is running. If the engine fails to
start, the starter will disengage automatically
in 10 seconds. If this occurs:
1. Place the ignition in the OFF mode.
2. Wait 10 to 15 seconds.
3. Repeat the “Normal Starting” procedure.
Extreme Cold Weather (Below –22°F Or
−30°C)
To ensure reliable starting at these tempera-
tures, use of an externally powered electric
engine block heater (available from an autho-
rized dealer) is recommended.
Normal Starting — Diesel Engine
Before starting your vehicle, adjust your seat,
both inside and outside mirrors, and fasten
your seat belts.
121

The starter is allowed to crank for up to
30-second intervals. Waiting a few minutes
between such intervals will protect the starter
from overheating.
WARNING!
• Before exiting a vehicle, always come toa complete stop, then shift the auto-
matic transmission into PARK and apply
the parking brake.
• Always make sure the keyless ignition
node is in the OFF mode, key fob is
removed from the vehicle and vehicle is
locked.
• Never leave children alone in a vehicle,
or with access to an unlocked vehicle.
Leaving children in a vehicle unattended
is dangerous for a number of reasons. A
child or others could be seriously or
fatally injured. Children should be
warned not to touch the parking brake,
brake pedal or the gear selector.
• Do not leave the key fob in or near the
vehicle, or in a location accessible to
children, and do not leave the ignition of
a vehicle equipped with Keyless Enter-
WARNING!
N-Go in the ACC or ON/RUN mode. A
child could operate power windows,
other controls, or move the vehicle.
• Do not leave children or animals inside
parked vehicles in hot weather. Interior
heat build-up may cause serious injury
or death.
NOTE:
Engine start up in very low ambient tempera-
ture could result in evident white smoke. This
condition will disappear as the engine warms
up.
CAUTION!
The engine is allowed to crank as long as
30 seconds. If the engine fails to start
during this period, please wait at least two
minutes for the starter to cool before re-
peating start procedure.
Battery Blanket Usage
A battery loses 60% of its cranking power as
the battery temperature decreases to 0°F
(-18°C). For the same decrease in tempera-
ture, the engine requires twice as much
power to crank at the same RPM. The use of
battery blankets will greatly increase starting
capability at low temperatures. Suitable bat-
tery blankets are available from your autho-
rized Mopar dealer.
Normal Starting Procedure — Keyless
Enter-N-Go
Observe the instrument panel cluster lights
when starting the engine.
NOTE:
Normal starting of either a cold or a warm
engine is obtained without pumping or press-
ing the accelerator pedal.
1. Always apply the parking brake.
2. Press and hold the brake pedal while pushing the ENGINE START/STOP button
once.STARTING AND OPERATING
122

NOTE:
A delay of the start of up to five seconds is
possible under very cold conditions. The
“Wait to Start” telltale will be illuminated
during the pre-heat process, When the
engine Wait To Start light goes off the
engine will automatically crank.
CAUTION!
If the “Water in Fuel Indicator Light” re-
mains on, DO NOT START the engine be-
fore the water is drained from the fuel
filters to avoid engine damage.
3. The system will automatically engage the starter to crank the engine. If the vehicle
fails to start, the starter will disengage
automatically after 30 seconds.
4. If you wish to stop the cranking of the engine prior to the engine starting, push
the button again.
5. Check that the oil pressure warning light has turned off.
6. Release the parking brake.
Engine Warm Up
Avoid full throttle operation when the engine
is cold. When starting a cold engine, bring the
engine up to operating speed slowly to allow
the oil pressure to stabilize as the engine
warms up.
NOTE:
High-speed, no-load running of a cold engine
can result in excessive white smoke and poor
engine performance. No-load engine speeds
should be kept under 1,200 RPM during the
warm-up period, especially in cold ambient
temperature conditions.
ENGINE BREAK-IN
RECOMMENDATIONS
A long break-in period is not required for the
engine and drivetrain (transmission and axle)
in your vehicle.
Drive moderately during the first 300 miles
(500 km). After the initial 60 miles
(100 km), speeds up to 50 or 55 mph (80 or
90 km/h) are desirable. While cruising, brief full-throttle acceleration
within the limits of local traffic laws contrib-
utes to a good break-in. Wide-open throttle
acceleration in low gear can be detrimental
and should be avoided.
The engine oil installed in the engine at the
factory is a high-quality energy conserving
type lubricant. Oil changes should be consis-
tent with anticipated climate conditions un-
der which vehicle operations will occur. For
the recommended viscosity and quality
grades, refer to “Fluids And Lubricants” in
“Technical Specifications”.
CAUTION!
Never use Non-Detergent Oil or Straight
Mineral Oil in the engine or damage may
result.
NOTE:
A new engine may consume some oil during
its first few thousand miles (kilometers) of
operation. This should be considered a nor-
mal part of the break-in and not interpreted
as a problem.

PARKING BRAKE
Electric Park Brake (EPB)
Your vehicle is equipped with a new Electric
Park Brake System (EPB) that offers greater
convenience. The park brake switch is lo-
cated in the center console.
To apply the park brake manually, pull up on
the switch momentarily. The BRAKE telltale
light in the instrument cluster and an indica-
tor on the switch will illuminate.To release the park brake manually, the igni-
tion must be in ON/RUN. Then put your foot
on the brake pedal and push the park brake
switch down momentarily. Once the park
brake is fully disengaged, the BRAKE telltale
light and the switch indicator will extinguish.
The park brake can also be automatically
released. With the engine running and the
transmission in gear, release the brake pedal
and depress the throttle pedal. For safety
reasons, your seat belt must also be fastened.
NOTE:
• You may hear a slight whirring sound from
the back of the vehicle while the parking
brake engages or disengages.
• If your foot is on the brake pedal while you are engaging or disengaging the parking
brake, you may notice a small amount of
brake pedal movement.
• The new Auto Park Brake feature can be used to apply the park brake automatically
every time you park the vehicle. Auto Park
Brake can be enabled and disabled in the
Settings menu in Uconnect. • The parking brake can be engaged even
when the ignition is OFF, however, it can
only be disengaged when the ignition is in
the ON/RUN mode.
•SafeHold a new feature that will automatically
apply the park brake under certain conditions.
The EPB monitors the status of the driver’s
seat belt, driver’s door and pedal positions to
determine if the driver may have exited while
the vehicle is still capable of moving and will
then automatically apply the park brake to
prevent the vehicle from rolling.
•The EPB fault light will illuminate if the EPB
switch is held for longer than 20 seconds in
either the released or applied position. The
light will extinguish upon releasing the
switch.
• Refer to the Starting And Operating section in the Owner’s Manual.
CAUTION!
If the Brake System Warning Light remains
on with the parking brake released, a brake
system malfunction is indicated. Have the
brake system serviced by an authorized
dealer immediately.Parking Brake Switch
