46GETTING TO KNOW YOUR INSTRUMENT PANEL
Electronic Throttle Control (ETC) Warning
Light
This warning light will illuminate to
inform of a problem with the ETC
system. If a problem is detected while
the vehicle is running, the light will
either stay on or flash depending on the nature of
the problem. Cycle the ignition when the vehicle is
safely and completely stopped and the
transmission is placed in the PARK (P) position.
The light should turn off. If the light remains on with
the vehicle running, your vehicle will usually be
drivable; however, see an authorized dealer for
service as soon as possible.
If the light continues to flash when the vehicle is
running, immediate service is required and you
may experience reduced performance, an
elevated/rough idle, or engine stall and your
vehicle may require towing. The light will come on
when the ignition is placed in the ON/RUN or MAR/
ON/RUN position and remain on briefly as a bulb
check. If the light does not come on during starting,
have the system checked by an authorized dealer.
Engine Coolant Temperature Warning
Light
This warning light warns of an
overheated engine condition. If the
engine coolant temperature is too high,
this indicator will illuminate and a single chime will sound. If the temperature reaches the
upper limit, a continuous chime will sound for four
minutes or until the engine is able to cool,
whichever comes first.
If the light turns on while driving, safely pull over
and stop the vehicle. If the Air Conditioning (A/C)
system is on, turn it off. Also, shift the transmission
into NEUTRAL (N) and idle the vehicle. If the
temperature reading does not return to normal,
turn the engine off immediately and call for service
Ú
page 183.
Oil Pressure Warning Light
This warning light will illuminate to
indicate low engine oil pressure. If the
light turns on while driving, stop the
vehicle, shut off the engine as soon as
possible, and contact an authorized dealer. A
chime will sound when this light turns on.
Do not operate the vehicle until the cause is
corrected. This light does not indicate how much oil
is in the engine. The engine oil level must be
checked under the hood.

Transmission Temperature Warning Light —
If Equipped

This warning light will illuminate to warn
of a high transmission fluid
temperature. This may occur with
strenuous usage such as trailer towing.
If this light turns on, stop the vehicle and run the engine at idle or slightly faster, with the
transmission in PARK (P) or NEUTRAL (N), until the
light turns off. Once the light turns off, you may
continue to drive normally.
Seat Belt Reminder Warning Light
When the ignition is first placed in the
ON/RUN or MAR/ON/RUN position, if
the driver’s seat belt is unbuckled, a
chime will sound and the light will turn
on. When driving, if the driver or front passenger
seat belt remains unbuckled, the Seat Belt
Reminder Light will flash or remain on continuously
and a chime will sound Ú page 137.
WARNING!
If you continue operating the vehicle when the
Transmission Temperature Warning Light is
illuminated you could cause the fluid to boil over,
come in contact with hot engine or exhaust
components and cause a fire.
CAUTION!
Continuous driving with the Transmission
Temperature Warning Light illuminated will
eventually cause severe transmission damage
or transmission failure.

22_VM_OM_EN_USC_t.book Page 46

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.

58STARTING AND OPERATING
The following indicators should be used to ensure
that you have properly engaged the transmission
into the PARK position:
When shifting into PARK, push the lock button
on the gear selector and firmly move the gear
selector all the way forward until it stops and is
fully seated.
Look at the transmission gear position display
and verify that it indicates the PARK position.
With brake pedal released, verify that the gear
selector will not move out of PARK.
REVERSE (R)
This range is for moving the vehicle backward.
Shift into REVERSE only after the vehicle has come
to a complete stop.
NEUTRAL (N)
Use this range when the vehicle is standing for
prolonged periods with the engine running. Apply
the parking brake and shift the transmission into
PARK if you must exit the vehicle.
DRIVE (D)
This range should be used for most city and
highway driving. It provides the smoothest upshifts
and downshifts, and the best fuel economy. The
transmission automatically upshifts through all
forward gears.
When frequent transmission shifting occurs (such
as when operating the vehicle under heavy loading
conditions, in hilly terrain, traveling into strong
head winds, or while towing a heavy trailer), use
the Electronic Range Select (ERS) shift control to
select a lower gear range Úpage 59. Under these
conditions, using a lower gear range will improve
performance and extend transmission life by
reducing excessive shifting and heat buildup.
If the transmission temperature exceeds normal
operating limits, the transmission controller may
modify the transmission shift schedule, reduce
engine torque, and/or expand the range of torque
converter clutch engagement. This is done to
prevent transmission damage due to overheating.
Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Allowing chil -
dren 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 ignition key in or near the
vehicle (or in a location accessible to chil-
dren). A child could operate power windows,
other controls, or move the vehicle.
CAUTION!
Before moving the transmission gear selector
out of PARK, you must turn the ignition to the
ON/RUN position, and also press the brake
pedal. Otherwise, damage to the gear selector
could result.
DO NOT race the engine when shifting from
PARK or NEUTRAL into another gear range, as
this can damage the drivetrain.
WARNING!
WARNING!
Do not coast in NEUTRAL and never turn off the
ignition to coast down a hill. These are unsafe
practices that limit your response to changing
traffic or road conditions. You might lose control
of the vehicle and have a collision.
CAUTION!
Towing the vehicle, coasting, or driving for any
other reason with the transmission in NEUTRAL
can cause severe transmission damage.
For Recreational Towing Ú page 75.
For Towing A Disabled Vehicle Ú page 187.

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.

22_VM_OM_EN_USC_t.book Page 62

68STARTING AND OPERATING
OVERLOADING
The load carrying components (axle, springs, tires,
wheels, etc.) of your vehicle will provide
satisfactory service as long as you do not exceed
the GVWR and the front and rear GAWR.
The best way to figure out the total weight of your
vehicle is to weigh it when it is fully loaded and
ready for operation. Weigh it on a commercial scale
to ensure that it is not over the GVWR.

Figure out the weight on the front and rear of the
vehicle separately. It is important that you distribute
the load evenly over the front and rear axles.

Overloading can cause potential safety hazards
and shorten useful service life. Heavier axles or
suspension components do not necessarily
increase the vehicle's GVWR.
LOADING
To load your vehicle properly, first figure out its
empty weight, axle-by-axle and side-by-side. Store
heavier items down low and be sure you distribute
their weight as evenly as possible. Stow all loose
items securely before driving. If weighing the
loaded vehicle shows that you have exceeded
either GAWR, but the total load is within the
specified GVWR, you must redistribute the weight.
Improper weight distribution can have an adverse
effect on the way your vehicle steers and handles
and the way the brakes operate.
NOTE:Refer to the “Vehicle Certification Label” affixed to
the B-pillar or the rear of the driver's door for your
vehicle's GVWR and GAWR.
TRAILER TOWING
In this section you will find safety tips and
information on limits to the type of towing you can
reasonably do with your vehicle. Before towing a
trailer, carefully review this information to tow your
load as efficiently and safely as possible.
To maintain the New Vehicle Limited Warranty
coverage, follow the requirements and
recommendations in this manual concerning
vehicles used for trailer towing.
COMMON TOWING DEFINITIONS
The following trailer towing related definitions will
assist you in understanding the following
information:
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total allowable weight of your
vehicle. This includes driver, passengers, cargo
and tongue weight. The total load must be limited
so that you do not exceed the GVWR Ú page 67.
Gross Combination Weight Rating (GCWR)
The GCWR is the total allowable weight of your
vehicle and trailer when weighed in combination.
Gross Trailer Weight (GTW)
The GTW is the weight of the trailer plus the weight
of all cargo, consumables and equipment
(permanent or temporary) loaded in or on the
trailer in its "loaded and ready for operation"
condition.
The recommended way to measure GTW is to put
your fully loaded trailer on a vehicle scale. The
entire weight of the trailer must be supported by
the scale.
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum capacity of the front
and rear axles. Distribute the load over the front
and rear axles evenly. Make sure that you do not
exceed either front or rear GAWR Úpage 67.
WARNING!
It is important that you do not exceed the
maximum front or rear GAWR. A dangerous
driving condition can result if either rating is
exceeded. You could lose control of the vehicle
and have a collision.

22_VM_OM_EN_USC_t.book Page 68

STARTING AND OPERATING69
Tongue Weight (TW)
The TW is the downward force exerted on the hitch
ball by the trailer. You must consider this as part of
the load on your vehicle.
Trailer Frontal Area
The frontal area is the maximum height multiplied
by the maximum width of the front of a trailer.
Trailer Sway Control (TSC)
The TSC can be a mechanical telescoping link that
can be installed between the hitch receiver and the
trailer tongue that typically provides adjustable
friction associated with the telescoping motion to
dampen any unwanted trailer swaying motions
while traveling.
If equipped, the electronic TSC recognizes a
swaying trailer and automatically applies individual
wheel brakes and/or reduces engine power to
attempt to eliminate the trailer sway.
Weight-Carrying Hitch
A weight-carrying hitch supports the trailer tongue
weight, just as if it were luggage located at a hitch
ball or some other connecting point of the vehicle.
These kinds of hitches are commonly used to tow
small and medium sized trailers.
Weight-Distributing Hitch
The weight-distributing hitch works by applying
leverage through spring (load) bars. They are
typically used for heavier loads to distribute trailer
tongue weight to the tow vehicle's front axle and
the trailer axle(s). When used in accordance with
the manufacturer's directions, it provides for a
more level ride, offering more consistent steering
and brake control thereby enhancing towing
safety. The addition of a friction/hydraulic sway
control also dampens sway caused by traffic and
crosswinds and contributes positively to tow vehicle and trailer stability. Trailer Sway Control
(TSC) and a weight distributing (load equalizing)
hitch are recommended for heavier Tongue
Weights (TW) and may be required depending on
vehicle and trailer configuration/loading to comply
with Gross Axle Weight Rating (GAWR)
requirements.WARNING!
An improperly adjusted Weight Distributing
Hitch system may reduce handling, stability,
braking performance, and could result in a
collision.
Weight Distributing Systems may not be
compatible with Surge Brake Couplers.
Consult with your hitch and trailer manufac-
turer or a reputable Recreational Vehicle
dealer for additional information.
