GETTING TO KNOW YOUR INSTRUMENT PANEL 87
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 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.
Refer to “If Your Engine Overheats” in “In Case Of Emer -
gency” for further information. 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.
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.

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 illu -
minate 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
alarm 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.
WARNING!
A malfunctioning catalytic converter, as referenced
above, can reach higher temperatures than in normal
operating conditions. This can cause a fire if you drive
slowly or park over flammable substances such as dry
plants, wood, cardboard, etc. This could result in death
or serious injury to the driver, occupants or others.
CAUTION!
Prolonged driving with the Malfunction Indicator Light
(MIL) on could cause damage to the vehicle control
system. It also could affect fuel economy and
driveability. If the MIL is flashing, severe catalytic
converter damage and power loss will soon occur.
Immediate service is required.3

94 GETTING TO KNOW YOUR INSTRUMENT PANEL
ONBOARD DIAGNOSTIC SYSTEM — OBD II
Your vehicle is equipped with a sophisticated Onboard
Diagnostic system called OBD II. This system monitors the
performance of the emissions, engine, and transmission
control systems. When these systems are operating properly,
your vehicle will provide excellent performance and fuel
economy, as well as engine emissions well within current
government regulations.
If any of these systems require service, the OBD II system
will turn on the Malfunction Indicator Light (MIL). It will
also store diagnostic codes and other information to assist
your service technician in making repairs. Although your
vehicle will usually be drivable and not need towing, see an
authorized dealer for service as soon as possible.
Onboard Diagnostic System (OBD II) Cybersecurity
Your vehicle is required to have an Onboard Diagnostic
system (OBD II) and a connection port to allow access to
information related to the performance of your emissions
controls. Authorized service technicians may need to access
this information to assist with the diagnosis and service of
your vehicle and emissions system.CAUTION!
• Prolonged driving with the MIL on could cause further damage to the emission control system. It could also
affect fuel economy and driveability. The vehicle must
be serviced before any emissions tests can be
performed.
• If the MIL is flashing while the vehicle is running, severe catalytic converter damage and power loss will
soon occur. Immediate service is required.

102 SAFETY
Traction Control System (TCS)
The Traction Control System (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 accelera-
tion and stability. A feature of the TCS system, Brake Limited
Differential (BLD), functions similar to a limited slip differ -
ential 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. Refer to “Electronic Stability
Control (ESC)” in this section for further information. Trailer Sway Control (TSC) — If Equipped
Trailer Sway Control (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 appro
-
priate wheel(s) to counteract the sway of the trailer. TSC will
become active automatically once an excessively swaying
trailer is recognized.
NOTE:
TSC cannot stop all trailers from swaying. Always use
caution when towing a trailer and follow the trailer tongue
weight recommendations. Refer to “Trailer Towing” in
“Starting And Operating” for further information.
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.

168 STARTING AND OPERATING
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. The DRIVE position
provides optimum driving characteristics under all normal
operating conditions.
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 refer to “Electronic Range Select (ERS) Opera
-
tion” in this section for further information to select a lower
gear range. 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 transmis -
sion 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.
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.
Refer to “Recreational Towing” in “Starting And
Operating” and “Towing A Disabled Vehicle” in “In
Case Of Emergency” for further information.

STARTING AND OPERATING 175
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 soft tap on the brake pedal, pushing the CAN button, or
normal brake pressure while slowing the vehicle will deacti-
vate the Speed Control 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).
Refer to “ParkSense Rear Park Assist System Usage Precau-
tions” in this section for limitations of this system and recom -
mendations.
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 OFF and then to ON again would be needed. If a
non-Mopar trailer hitch is mounted, the sensor deactivation
cannot be guaranteed.
