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

STARTING AND OPERATING
119

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
STARTING AND OPERATING

WARNING!
• Never use the PARK position as a sub-stitute for the parking brake. Always ap-
ply the parking brake fully when exiting
the vehicle to guard against vehicle
movement and possible injury or dam-
age.
• When exiting the vehicle, always make
sure the ignition is in the OFF mode,
remove the key fob from the vehicle, and
lock your 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 transmission
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
in the ACC or ON/RUN mode. A child
WARNING!
could operate power windows, other con-
trols, or move the vehicle.
• Be sure the parking brake is fully disen-
gaged before driving; failure to do so can
lead to brake failure and a collision.
• Always fully apply the parking brake
when leaving your vehicle, or it may roll
and cause damage or injury. Also be
certain to leave the transmission in
PARK. Failure to do so may allow the
vehicle to roll and cause damage or in-
jury.
• Driving the vehicle with the parking
brake engaged, or repeated use of the
parking brake to slow the vehicle may
cause serious damage to the brake sys-
tem.
Auto Park Brake
The electric park brake can be programmed
to be applied automatically whenever the
vehicle is at a standstill and the automatic
transmission is placed in PARK, or with a
manual transmission, whenever the ignition
is turned “OFF”. Auto Park Brake is enabled and disabled by customer selection through
the customer programmable features section
of the Uconnect Settings.
Any single auto park brake application can be
bypassed by pushing the EPB switch to the
release position while the transmission is
placed in PARK.
SafeHold
SafeHold is a safety feature of the Electric
Park Brake System that will engage the park
brake automatically if the vehicle is left un-
secured while the ignition is in ON/RUN.
For automatic transmissions, the park brake
will automatically engage if all of the follow-
ing conditions are met:
• The vehicle is at a standstill.
• There is no attempt to depress the brake
pedal or accelerator pedal.
• The seat belt is unbuckled.
• The driver door is open.
125

For manual transmissions, the park brake will
automatically engage if all of the following
conditions are met:
• The vehicle is at a standstill.
• There is no attempt to depress the brakepedal or accelerator pedal.
• The clutch pedal is not pressed.
• The seat belt is unbuckled.
• The driver door is open.
SafeHold can be temporarily bypassed by
pushing the Electric Park Brake Switch while
the driver door is open. Once manually by-
passed, SafeHold will be enabled again once
the vehicle reaches 12 mph (20 km/h) or the
ignition is turned to the OFF position and
back to ON again.MANUAL TRANSMISSION —
IF EQUIPPED
WARNING!
You or others could be injured if you leave
the vehicle unattended without having the
parking brake fully applied. The parking
brake should always be applied when the
driver is not in the vehicle, especially on
an incline.
CAUTION!
Never drive with your foot resting on the
clutch pedal, or attempt to hold the ve-
hicle on a hill with the clutch pedal par-
tially engaged, as this will cause abnormal
wear on the clutch. NOTE:
During cold weather, you may experience
increased effort in shifting until the transmis-
sion fluid warms up. This is normal.
Shifting
Fully press the clutch pedal before shifting
gears. As you release the clutch pedal, lightly
press the accelerator pedal.
You should always use first gear when starting
from a standing position.
Recommended Vehicle Shift Speeds
To utilize your manual transmission effi-
ciently for fuel economy and performance, it
should be upshifted as listed in the recom-
mended shift speed chart. Shift at the ve-
hicle speeds listed for acceleration. When
heavily loaded or pulling a trailer, these rec-
ommended up-shift speeds may not apply.

Downshifting
Moving from a high gear down to a lower gear
is recommended to preserve brakes when
driving down steep hills. In addition, down-
shifting at the right time provides better ac-
celeration when you desire to resume speed.
Downshift progressively. Do not skip gears to
avoid overspeeding the engine and clutch.
WARNING!
Do not downshift for additional engine
braking on a slippery surface. The drive
wheels could lose their grip, and the ve-
hicle could skid.
CAUTION!
• Skipping gears and downshifting intolower gears at higher vehicle speeds can
damage the engine and clutch systems,
CAUTION!
Any attempt to shift into lower gear with
clutch pedal depressed may result dam-
age to the clutch system. Shifting into
lower gear and releasing the clutch may
result in engine damage.
• When descending a hill, be very careful
to downshift one gear at a time to pre-
vent overspeeding the engine which can
cause engine damage, and/or clutch
damage, even if the clutch pedal is
pressed. If transfer case is in low range
the vehicle speeds to cause engine and
clutch damage are significantly lower.
• Failure to follow the maximum recom-
mended downshifting speeds may cause
the engine damage and/or damage the
clutch, even if the clutch pedal is
pressed.
CAUTION!
• Descending a hill in low range withclutch pedal depressed could result in
clutch damage.
Maximum Recommended Downshift Speeds
CAUTION!
Failure to follow the maximum recom-
mended downshifting speeds may cause
the engine to overspeed and/or damage the
clutch disc, even if the clutch pedal is
pressed.
