• Vehicle speed exceeds 20 mph (32 km/h)but remains below 40 mph (64 km/h).
• Vehicle is shifted to PARK.
Disabling SSC
SSC will deactivate and be disabled if any of
the following conditions occur:
• The driver pushes the SSC switch.
• The driveline is shifted out of 4WD Low Range.
• The parking brake is applied.
• Driver door opens.
• The vehicle is driven greater than 20 mph (32 km/h) for greater than 70 seconds.
• The vehicle is driven greater than 40 mph (64 km/h) (SSC exits immediately).
Feedback To The Driver:
The instrument cluster has an SSC icon and
the SSC switch has an LED which offer feed-
back to the driver about the state SSC is in. • The cluster icon and switch lamp will illu-
minate and remain on solid when SSC is
enabled or activated. This is the normal
operating condition for SSC.
• The cluster icon and switch lamp will flash for several seconds then extinguish when
the driver pushes the SSC switch but en-
able conditions are not met.
• The cluster icon and switch lamp will flash for several seconds then extinguish when
SSC disables due to excess speed.
• The cluster icon and switch lamp will flash then extinguish when SSC deactivates due
to overheated brakes.
WARNING!
SSC is only intended to assist the driver in
controlling vehicle speed when driving in
off road conditions. The driver must re-
main attentive to the driving conditions
and is responsible for maintaining a safe
vehicle speed.
AUXILIARY DRIVING
SYSTEMS
Blind Spot Monitoring
The Blind Spot Monitoring (BSM) system
uses two radar-based sensors, located inside
the rear bumper fascia, to detect highway
licensable vehicles (automobiles, trucks, mo-
torcycles etc.) that enter the blind spot zones
from the rear/front/side of the vehicle.
The BSM detection zone covers approxi-
mately one lane width on both sides of the
vehicle 12 ft (3.8 m). The zone length starts
at the outside rear view mirror and extends
approximately 10 ft (3 m) beyond the rear
bumper of the vehicle. The BSM system
monitors the detection zones on both sides of
the vehicle when the vehicle speed reaches
approximately 6 mph (10 km/h) or higher and
will alert the driver of vehicles in these areas.

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.

your vehicle. If equipped with Keyless
Enter-N-Go, always make sure the key-
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

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.
