GETTING TO KNOW YOUR INSTRUMENT PANEL47
Transmission Fault Warning Light
This light will illuminate (together with a
message in the instrument cluster
display and a buzzer) to indicate a
transmission fault. Contact an
authorized dealer if the message remains after
restarting the engine.
Engine Oil Level Warning Light
This warning light appears on the panel
when the engine oil level falls below the
minimum recommended value. Restore
the correct engine oil level or contact an
authorized dealer for service.
YELLOW WARNING LIGHTS
Anti-Lock Brake System (ABS) Warning
Light
This light monitors the ABS. The light will
turn on when the ignition is placed in the
ON/RUN or MAR/ON/RUN position and
may stay on for as long as four seconds.
If the ABS light remains on or turns on while
driving, then the Anti-Lock portion of the brake
system is not functioning and service is required.
However, the conventional brake system will
continue to operate normally if the brake warning
light is not on. If the ABS light is on, the brake system should be
serviced as soon as possible to restore the
benefits of Anti-Lock Brakes. If the ABS light does
not turn on when the ignition is placed in the ON/
RUN or MAR/ON/RUN position, have the light
inspected by an authorized dealer.
Low Fuel Warning Light
When the fuel level reaches
approximately 2–3 gal (9–11 L) this
light will turn on, and remain on until
fuel is added.
Generic Warning Light
The Generic Warning Light will
illuminate if any of the following
conditions occur: Engine Oil Pressure
Sensor Failure, External Light Failure,
Parking Sensor Failure, Fuel Cut-Off Fail/
Intervention, Generic Failure on Trailer, or Air Bag
telltale recovery.
The telltale will blink in case of an Air Bag Warning
Light Failure. Contact an authorized dealer
immediately for service.
Tire Pressure Monitoring System (TPMS)
Warning Light
The warning light switches on and a
message is displayed to indicate that
the tire pressure is lower than the
recommended value and/or that slow
pressure loss is occurring. In these cases, optimal
tire duration and fuel consumption may not be
guaranteed.
Should one or more tires be in the condition
mentioned above, the display will show the
indications corresponding to each tire.
Each tire, including the spare (if provided), should be
checked monthly when cold and inflated to the
inflation pressure recommended by the vehicle
manufacturer on the vehicle placard or tire inflation
pressure label. If your vehicle has tires of a different
size than the size indicated on the vehicle placard or
tire inflation pressure label, you should determine the
proper tire inflation pressure for those tires.
CAUTION!
Do not continue driving with one or more flat
tires as handling may be compromised. Stop the
vehicle, avoiding sharp braking and steering. If a
tire puncture occurs, repair immediately using
the dedicated tire repair kit and contact an
authorized dealer as soon as possible.

48GETTING TO KNOW YOUR INSTRUMENT PANEL
As an added safety feature, your vehicle has been
equipped with a TPMS that illuminates a low tire
pressure telltale when one or more of your tires is
significantly underinflated. Accordingly, when the low
tire pressure telltale illuminates, you should stop and
check your tires as soon as possible, and inflate them
to the proper pressure. Driving on a significantly
underinflated tire causes the tire to overheat and can
lead to tire failure. Underinflation also reduces fuel
efficiency and tire tread life, and may affect the
vehicle’s handling and stopping ability.
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver’s
responsibility to maintain correct tire pressure, even
if underinflation has not reached the level to trigger
illumination of the TPMS low tire pressure telltale.
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the system
is not operating properly. The TPMS malfunction
indicator is combined with the low tire pressure
telltale. When the system detects a malfunction,
the telltale will flash for approximately one minute
and then remain continuously illuminated. This
sequence will continue upon subsequent vehicle
start-ups as long as the malfunction exists. When
the malfunction indicator is illuminated, the
system may not be able to detect or signal low tire
pressure as intended. TPMS malfunctions may
occur for a variety of reasons, including the
installation of replacement or alternate tires or wheels on the vehicle that prevent the TPMS from
functioning properly. Always check the TPMS
malfunction telltale after replacing one or more
tires or wheels on your vehicle to ensure that the
replacement or alternate tires and wheels allow
the TPMS to continue to function properly.
Vehicle Security Warning Light
This warning light will illuminate when
the vehicle security system has
detected an attempt to break into the
vehicle.
Engine Check/Malfunction Indicator
Warning Light (MIL)
The Engine Check/Malfunction Indicator
Light (MIL) is a part of an Onboard
Diagnostic System called OBD II that
monitors engine and automatic
transmission control systems. This warning light will
illuminate when the ignition is in the ON/RUN position
before engine start. After placing the ignition to the
ON/RUN position, if there is a problem with the Sentry
Key System, the Vehicle Security Light will turn on.
This condition will result in the engine being shut off
after two seconds. If the bulb does not come on when
turning the ignition switch from OFF to ON/RUN, have
the condition checked promptly.
NOTE:This warning light will illuminate when the vehicle
security system has detected an attempt to break
into the vehicle.
Certain conditions, such as a loose or missing gas
cap, poor quality fuel, etc., may illuminate the light
after engine start. The vehicle should be serviced if
the light stays on through several typical driving
styles. In most situations, the vehicle will drive
normally and will not require towing.
When the engine is running, the MIL may flash to alert
serious conditions that could lead to immediate loss
of power or severe catalytic converter damage. The
vehicle should be serviced by an authorized dealer as
soon as possible if this occurs.
CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures
and warning have been established for the tire
size equipped on your vehicle. Undesirable
system operation or sensor damage may result
when using replacement equipment that is not
of the same size, type, and/or style. Aftermarket
wheels can cause sensor damage. Using
aftermarket tire sealants may cause the Tire
Pressure Monitoring System (TPMS) sensor to
become inoperable. After using an aftermarket
tire sealant it is recommended that you take
your vehicle to an authorized dealer to have your
sensor function checked.

STARTING AND OPERATING
STARTING THE ENGINE
Before starting your vehicle, adjust your seat,
adjust both inside and outside mirrors, and fasten
your seat belts.
AUTOMATIC TRANSMISSION
The gear selector must be in the PARK (P) or
NEUTRAL (N) position before you can start the
engine. Press the brake pedal before shifting to
any driving gear.
NOTE:You must press the brake pedal before shifting out
of PARK.
NORMAL STARTING
Turn the ignition switch to the AVV (START) position
and release it when the engine starts. If the engine
fails to start within 10 seconds, turn the ignition
switch to the STOP (OFF/LOCK) position, wait 10 to
15 seconds, then repeat this procedure.
COLD WEATHER OPERATION
To ensure reliable starting at low temperatures,
use of an externally powered electric engine block
heater (available from an authorized dealer) is
recommended.
To prevent possible engine damage while starting
at low temperatures, this vehicle will inhibit engine
cranking when the ambient temperature is less
than -31°F (-35° C) and the oil temperature
sensor reading indicates an engine block heater
has not been used. The message “Plug In Engine
Heater” will be displayed in the instrument cluster
when the ambient temperature is below -25°F
(-32° C) at the time the engine is shut off as a
reminder.
EXTENDED PARK STARTING
NOTE:Extended Park condition occurs when the vehicle
has not been started or driven for at least 30 days.
1. Install a battery charger or jumper cables to the battery to ensure a full battery charge
during the crank cycle.
2. Place the ignition in the AVV (START) position and release it when the engine starts.
3. If the engine fails to start within ten seconds, place the ignition in the STOP (OFF/LOCK)
position, wait 10 to 15 seconds to allow the
starter to cool, then repeat the Extended Park
Starting procedure.
4. If the engine fails to start after eight attempts, allow the starter to cool for at least
10 minutes, then repeat the procedure.
WARNING!
Never leave children alone in a vehicle, or with
access to an unlocked vehicle.
Allowing children to be 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 transmis -
sion gear selector.
Do not leave the key fob in or near the vehicle
(or in a location accessible to children). A child
could operate power windows, other controls,
or move the vehicle.
CAUTION!
To prevent damage to the starter, do not crank
continuously for more than 10 seconds at a
time. Wait 10 to 15 seconds before trying again.

62STARTING AND OPERATING
Using Cruise Control On Hills
The transmission may downshift on hills to
maintain the vehicle set speed.
NOTE:The Cruise Control system maintains speed up and
down hills. A slight speed change on moderate hills
is normal. On steep hills, a greater speed loss or
gain may occur so it may be preferable to drive
without Cruise Control.
TO RESUME SPEED
To resume a previously set speed, push the RES (+)
button and release. Resume can be used at any
speed above 20 mph (32 km/h) up to the
maximum speed of 100 mph (160 km/h).
TO DEACTIVATE
A tap on the brake pedal, pushing the CAN button,
or normal brake pressure will deactivate the Cruise
Control system without erasing the set speed from
memory.
Pushing the on/off button or turning the ignition
switch off erases the set speed from memory.
PARKSENSE REAR PARK ASSIST —
IF EQUIPPED
The ParkSense system provides an audible
indication of the distance between the rear fascia/
bumper and a detected obstacle when backing up
(e.g. during a parking maneuver) Ú page 64.
The ParkSense system is automatically activated
when the transmission is placed into REVERSE. As
the distance from an obstacle behind the vehicle
decreases, the audible alert becomes more frequent.
Interaction With Trailer Towing
The ParkSense system is automatically
deactivated when a trailer equipped by Mopar® is
hitched to the vehicle. The system will be
automatically activated as soon as the trailer is
removed. If it does not happen, turning the key
ignition switch to STOP (OFF/LOCK) position and
then to AVV (START) again would be needed. If a
non-Mopar® trailer hitch is mounted, the sensor
deactivation cannot be guaranteed.
PARKSENSE REAR PARK ASSIST
S
ENSORS
The four ParkSense sensors, located in the rear
fascia/bumper, monitor the area behind the vehicle
that is within the sensors’ field of view. The sensors
can detect obstacles, in the horizontal direction,
from approximately 12 inches (30 cm) up to
55 inches (140 cm) from the center of the rear
fascia/bumper and up to 24 inches (60 cm) from
the corners of the rear fascia/bumper, depending on
the location, type and orientation of the obstacle.
ParkSense Rear Park Assist Sensors Locations
If several obstacles are detected, the ParkSense
system indicates the nearest obstacle.
The minimum height of a detectable obstacle
corresponds to the maximum height of an obstacle
that would clear the underside of the vehicle
during the parking maneuver.
WARNING!
Cruise Control can be dangerous where the
system cannot maintain a constant speed. Your
vehicle could go too fast for the conditions, and
you could lose control and have an accident. Do
not use Cruise Control in heavy traffic or on
roads that are winding, icy, snow-covered or
slippery.

STARTING AND OPERATING63
PARKSENSE REAR PARK ASSIST
A
LERTS
If an obstacle is behind the vehicle when REVERSE gear is engaged, an audible alert is activated.
The tones emitted by the loudspeaker inform the driver that the vehicle is approaching an obstacle. The pauses between the tones are directly proportional to
the distance from the obstacle. Pulses emitted in quick succession indicate the presence of a very close obstacle. A continuous tone indicates that the obstacle
is less than 12 inches (30 cm) away.
While audible signals are emitted, the audio system is muted.
The audible signal is turned off immediately if the distance increases. The tone cycle remains constant if the distance measured by the inner sensors is constant.
If this condition occurs for the external sensors, the signal is turned off after three seconds (stopping warnings during maneuvers parallel to walls).

AILURE INDICATIONS
A malfunction of the ParkSense sensors
or system is indicated, during REVERSE
gear engagement, by the instrument
panel warning icon.
The warning icon is illuminated and a message is
displayed on the instrument cluster display (if
equipped) Ú page 44.
The sensors and wiring are tested continuously
when the ignition is in the MAR (ACC/ON/RUN)
position. Failures are indicated immediately if they
occur when the system is on.
Even if the system is able to identify that a specific
sensor is in failure condition, the instrument
cluster display shall indicate that the ParkSense
system is unavailable, without reference to the
sensor in failure condition. If even a single sensor
fails, the entire system will be disabled. The system
is turned off automatically.
CLEANING THE PARKSENSE REAR PARK
A
SSIST SYSTEM
Clean the ParkSense sensors with water, car wash
soap and a soft cloth. Do not use rough or hard
cloths. In washing stations, clean sensors quickly
while keeping the vapor jet/high pressure washing
nozzles at least 4 inches (10 cm) from the sensors. Do not scratch or poke the sensors. Otherwise, you
could damage the sensors.
PARKSENSE REAR PARK ASSIST
S
YSTEM USAGE PRECAUTIONS
NOTE:
Ensure that the outer surface and the underside
of the rear fascia/bumper is clean and clear of
snow, ice, mud, dirt or other obstruction to keep
the ParkSense Rear Park Assist system oper -
ating properly.
Jackhammers, large trucks, and other vibra -
tions could affect the performance of the
ParkSense system.
Clean the ParkSense sensors regularly, taking
care not to scratch or damage them. The sensors
must not be covered with ice, snow, slush, mud,
dirt or debris. Failure to do so can result in the
system not working properly. The ParkSense
system might not detect an obstacle behind the
fascia/bumper, or it could provide a false indica -
tion that an obstacle is behind the fascia/bumper.
Objects such as bicycle carriers, etc., must not
be placed within 12 inches (30 cm) from the
rear fascia/bumper while driving the vehicle.
Failure to do so can result in the system misin -
terpreting a close object as a sensor problem,
causing a failure indication to be displayed in
the instrument cluster display.
WARNING!
Drivers must be careful when backing up even
when using ParkSense. Always check carefully
behind your vehicle, look behind you, and be
sure to check for pedestrians, animals, other
vehicles, obstructions, and blind spots before
backing up. You are responsible for safety and
must continue to pay attention to your
surroundings. Failure to do so can result in
serious injury or death.
Before using ParkSense, it is strongly recom -
mended that the ball mount and hitch ball
assembly be disconnected from the vehicle
when the vehicle is not used for towing.
Failure to do so can result in injury or damage
to vehicles or obstacles because the hitch
ball will be much closer to the obstacle than
the rear fascia when the vehicle sounds the
continuous tone. Also, the sensors could
detect the ball mount and hitch ball
assembly, depending on its size and shape,
giving a false indication that an obstacle is
behind the vehicle.
22_VM_OM_EN_USC_t.book Page 64
Page 67 of 260

STARTING AND OPERATING65
If it’s necessary to keep the ball mount and hitch
ball assembly mounted for a long period, it is
possible to filter out the ball mount and hitch ball
assembly presence in the sensor field of view. The
filtering operation must be performed only by an
authorized dealer.
PARKVIEW REAR BACK UP CAMERA
Your vehicle is equipped with the ParkView Rear
Back Up Camera that allows you to see an
on-screen image of the rear surroundings of your
vehicle whenever the gear selector is put into
REVERSE. The image will be displayed on the
touchscreen display along with a caution note to “Check Entire Surroundings” across the top of the
screen. After five seconds this note will disappear.
The ParkView camera is located on the rear of the
vehicle above the rear license plate.
The Rear Back Up Camera can also be activated
when the vehicle is not in REVERSE through the
Uconnect system Ú
page 79.
NOTE:If one of the rear cargo doors is not completely
closed, the Back Up Camera cannot provide an
accurate image of the area behind the vehicle. A
dedicated message will appear on the Uconnect
display indicating the camera is not in the correct
position.
The Camera Delay setting can be set to on/off in
the rear camera settings menu. When the vehicle
is shifted out of REVERSE and the Camera Delay is
turned off, the rear camera mode is exited and the
navigation or audio screen appears on display
again.
When the transmission is shifted out of REVERSE,
and Camera Delay is activated in the menu screen,
the camera image will continue to be displayed for
up to 10 seconds, unless the speed of the vehicle
is greater than 8 mph (13 km/h), the transmission
is in PARK, or the ignition is placed in the STOP
(OFF/LOCK) position. When displayed, static grid lines will illustrate the
width of the vehicle and will show separate zones
that will help indicate the distance to the rear of
the vehicle. The following table shows the
approximate distances for each zone:
CAUTION!
ParkSense is only a parking aid and it is
unable to recognize every obstacle, including
small obstacles. Parking curbs might be
temporarily detected or not detected at all.
Obstacles located above or below the sensors
will not be detected when they are in close
proximity.
The vehicle must be driven slowly when using
ParkSense in order to be able to stop in time
when an obstacle is detected. It is recom
-
mended that the driver looks over his/her
shoulder when using ParkSense.
Zone Distance To The Rear
Of The Vehicle
Red 0 - 1 ft (0 - 30 cm)
Yellow 1 ft - 3 ft (30 cm - 1 m)
Green 3 ft or greater
(1 m or greater)
WARNING!
Drivers must be careful when backing up even
when using the ParkView Rear Back Up Camera.
Always check carefully behind your vehicle, and
be sure to check for pedestrians, animals, other
vehicles, obstructions, or blind spots before
backing up. You are responsible for the safety of
your surroundings and must continue to pay
attention while backing up. Failure to do so can
result in serious injury or death.

ELECTRONIC BRAKE CONTROL (EBC)
S
YSTEM
Your vehicle is equipped with an advanced
Electronic Brake Control (EBC) system that
includes the Brake Assist System (BAS), Traction
Control System (TCS), Hill Start Assist (HSA),
Electronic Stability Control (ESC), Electronic Roll
Mitigation (ERM) and Trailer Sway Control (TSC). All
systems work together to enhance vehicle stability
and control in various driving conditions and are
commonly referred to as ESC.
Brake Assist System (BAS)
BAS is designed to optimize the vehicle’s braking
capability during emergency braking maneuvers.
The system detects an emergency braking
situation by sensing the rate and amount of brake
application and then applies optimum pressure to
the brakes. This can help reduce braking
distances. The BAS complements the Anti-Lock
Brake System (ABS). Applying the brakes very
quickly results in the best BAS assistance. To
receive the benefit of the system, you must apply
continuous braking pressure during the stopping
sequence (do not “pump” the brakes). Do not
reduce brake pedal pressure unless braking is no
longer desired. Once the brake pedal is released,
the BAS is deactivated.Electronic Stability Control (ESC)
ESC enhances directional control and stability of
the vehicle under various driving conditions. ESC
corrects for over/under steering of the vehicle by
applying the brake of the appropriate wheel to
counteract the above conditions. Engine power
may also be reduced to help the vehicle maintain
the desired path.
Oversteer — when the vehicle is turning more
than appropriate for the steering wheel position.
Understeer — when the vehicle is turning less
than appropriate for the steering wheel position. ESC uses sensors in the vehicle to determine the
vehicle path intended by the driver and compares
it to the actual path of the vehicle. When the actual
path does not match the intended path, ESC
applies the brake of the appropriate wheel to
assist in counteracting the oversteer or understeer
condition.
WARNING!
The Brake Assist System (BAS) cannot prevent
the natural laws of physics from acting on the
vehicle, nor can it increase the traction afforded
by prevailing road conditions. BAS cannot
prevent collisions, including those resulting from
excessive speed in turns, driving on very slippery
surfaces, or hydroplaning. The capabilities of a
BAS-equipped vehicle must never be exploited in
a reckless or dangerous manner, which could
jeopardize the user's safety or the safety of
others.
WARNING!
Electronic Stability Control (ESC) cannot
prevent the natural laws of physics from
acting on the vehicle, nor can it increase the
traction afforded by prevailing road condi
-
tions. ESC cannot prevent accidents, including
those resulting from excessive speed in turns,
driving on very slippery surfaces, or hydro -
planing. ESC also cannot prevent accidents
resulting from loss of vehicle control due to
inappropriate driver input for the conditions.
Only a safe, attentive, and skillful driver can
prevent accidents. The capabilities of an ESC
equipped vehicle must never be exploited in a
reckless or dangerous manner which could
jeopardize the user’s safety or the safety of
others.
22_VM_OM_EN_USC_t.book Page 132
Page 136 of 260

134SAFETY
Hill Start Assist (HSA)
HSA is designed to assist the driver when starting
a vehicle from a stop on a hill. HSA will maintain
the level of brake pressure the driver applied for a
short period of time after the driver takes their foot
off of the brake pedal. If the driver does not apply
the throttle during this short period of time, the
system will release brake pressure and the vehicle
will roll down the hill. The system will release brake
pressure in proportion to the amount of throttle
applied as the vehicle starts to move in the
intended direction of travel.
HSA ACTIVATION CRITERIA
The following criteria must be met in order for HSA
to activate:
The vehicle must be stopped.
The vehicle must be on a 5% (approximate)
grade or greater hill.
Gear selection matches vehicle uphill direction
(i.e., vehicle facing uphill is in forward gear;
vehicle backing uphill is in REVERSE gear).
HSA will work in REVERSE and all forward gears
when the activation criteria have been met. The
system will not activate if the vehicle is placed in
NEUTRAL or PARK.
Traction Control System (TCS)
TCS monitors the amount of wheel spin of each of
the driven wheels. If wheel spin is detected, brake
pressure is applied to the slipping wheel(s) and
engine power is reduced to provide enhanced
acceleration and stability. A feature of the TCS
system, Brake Limited Differential (BLD) functions
similarly to a limited slip differential and controls
the wheel spin across a driven axle. If one wheel on
a driven axle is spinning faster than the other, the
system will apply the brake of the spinning wheel.
This will allow more engine torque to be applied to
the wheel that is not spinning. This feature remains
active even if TCS and ESC are in the “Partial Off”
mode Ú page 132.
Trailer Sway Control (TSC) — If Equipped
TSC uses sensors in the vehicle to recognize an
excessively swaying trailer and will take the
appropriate actions to attempt to stop the sway.
The system may reduce engine power and apply
the brake of the appropriate wheel(s) to counteract
the sway of the trailer.
NOTE:TSC cannot stop all trailers from swaying. Always
use caution when towing a trailer and follow the
trailer tongue weight recommendations
Úpage 68.
When TSC is functioning, the ESC Activation/
Malfunction Indicator Light will flash, the engine
power may be reduced and you may feel the
brakes being applied to individual wheels to
attempt to stop the trailer from swaying. TSC is
disabled when the ESC system is in the “Partial
Off” mode.
WARNING!
There may be situations on minor hills with a
loaded vehicle, or while pulling a trailer, when
the system will not activate and slight rolling may
occur. This could cause a collision with another
vehicle or object. Always remember the driver is
responsible for braking the vehicle.
WARNING!
If TSC activates while driving, slow the vehicle
down, stop at the nearest safe location, and
adjust the trailer load to eliminate trailer sway.
