NOTE:
The Remote Start Comfort System can be activated and deac-
tivated through the Uconnect System. Refer to “Uconnect
Settings” in “Multimedia” for further information on
Remote Start Comfort System operation.
General Information
The following regulatory statement applies to all radio
frequency (RF) devices equipped in this vehicle:
This device complies with Part 15 of the FCC Rules and with
Industry Canada license-exempt RSS standard(s). Operation
is subject to the following two conditions:
1. This device may not cause harmful interference, and
2. This device must accept any interference received, including interference that may cause undesired opera -
tion.
NOTE:
Changes or modifications not expressly approved by the
party responsible for compliance could void the user’s
authority to operate the equipment.
SENTRY KEY
The Sentry Key Immobilizer system prevents unauthorized
vehicle operation by disabling the engine. The system does
not need to be armed or activated. Operation is automatic,
regardless of whether the vehicle is locked or unlocked.
The system uses a key fob, keyless push button ignition and
a RF receiver to prevent unauthorized vehicle operation.
Therefore, only key fobs that are programmed to the vehicle
can be used to start and operate the vehicle. The system
cannot reprogram a key fob obtained from another vehicle.
After turning the ignition switch to the ON/RUN position,
the vehicle security light will turn on for three seconds for a
bulb check. If the light remains on after the bulb check, it
indicates that there is a problem with the electronics. In addi -
tion, if the light begins to flash after the bulb check, it indi -
cates that someone attempted to start the engine with an
invalid key fob. In the event that a valid key fob is used to
start the engine but there is an issue with the vehicle elec -
tronics, the engine will start and shut off after two seconds.

each side of the instrument cluster display will flash to show
proper operation of the front and rear turn signal lights.
NOTE:
If either light remains on and does not flash, or there is a very
fast flash rate, check for a defective outside light bulb. If an
indicator fails to light when the lever is moved, it would
suggest that the indicator bulb is defective.
Lane Change Assist — If Equipped
Tap the multifunction lever up or down once, without
moving beyond the detent, and the turn signal (right or left)
will flash three times then automatically turn off.

WARNING LIGHTS AND MESSAGES
The warning/indicator lights will illuminate in the instru-
ment panel together with a dedicated message and/or
acoustic signal when applicable. These indications are indic-
ative and precautionary and as such must not be considered
as exhaustive. Always refer to the information in this chapter
in the event of a failure indication. All active telltales will
display first if applicable. The system check menu may
appear different based upon equipment options and current
vehicle status. Some telltales are optional and may not
appear.
Red Warning Lights
— Seat Belt Reminder Warning Light
This warning light indicates when the driver or passenger
seat belt is unbuckled. When the ignition is first placed in the
ON/RUN or ACC/ON/RUN position and 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.
Refer to “Occupant Restraint Systems” in “Safety” for
further information. — Air Bag Warning Light
This warning light will illuminate to indicate a fault with the
air bag, and will turn on for four to eight seconds as a bulb
check when the ignition is placed in the ON/RUN or ACC/
ON/RUN position. This light will illuminate with a single
chime when a fault with the air bag has been detected, it will
stay on until the fault is cleared. If the light is either not on
during startup, stays on, or turns on while driving, have the
system inspected at an authorized dealer as soon as possible.
— Brake Warning Light
This warning light monitors various brake functions,
including brake fluid level and parking brake application. If
the brake light turns on it may indicate that the parking
brake is applied, that the brake fluid level is low, or that there
is a problem with the anti-lock brake system reservoir.
If the light remains on when the parking brake has been
disengaged, and the fluid level is at the full mark on the
master cylinder reservoir, it indicates a possible brake
hydraulic system malfunction or that a problem with the
Brake Booster has been detected by the Anti-Lock Brake
System (ABS) / Electronic Stability Control (ESC) system. In
this case, the light will remain on until the condition has been
corrected. If the problem is related to the brake booster, the

GETTING TO KNOW YOUR INSTRUMENT PANEL 149
— Electronic Throttle Control (ETC) Warning Light
This warning light will illuminate to indicate a problem with
the Electronic Throttle Control (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 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.
NOTE:
This light may turn on if the accelerator and brake pedals are
pressed at the same time.
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
ACC/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. — Trailer Brake Disconnected Warning Light
This warning light will illuminate when the Trailer Brake has
been disconnected.
— Transmission Temperature Warning Light — If
Equipped
This warning light will illuminate to warn of a high transmis -
sion 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 trans -
mission in PARK or NEUTRAL, 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.
CAUTION!
Continuous driving with the Transmission Temperature
Warning Light illuminated will eventually cause severe
transmission damage or transmission failure.

— Door Open Warning Light
This indicator will illuminate when a door is ajar/open and
not fully closed.
NOTE:
If the vehicle is moving there will also be a single chime.
Yellow Warning Lights
— Adaptive Cruise Control (ACC) Fault Warning Light
— If Equipped
This warning light will illuminate to indicate a fault in the
ACC system. Contact a local authorized dealer for service.
For further information, refer to “Adaptive Cruise Control
(ACC)” in “Starting And Operating.”
— 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. If the bulb does not come on when turning the ignition switch from OFF
to ON/RUN, have the condition checked promptly.
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.

— ECO Mode Indicator Light
This light will turn on when ECO Mode is active.
— Park/Headlight On Indicator Light
This indicator light will illuminate when the park lights or
headlights are turned on.
— Front Fog Indicator Light — If Equipped
This indicator light will illuminate when the front fog lights
are on.
— Turn Signal Indicator Lights
When the left or right turn signal is activated, the turn signal
indicator will flash independently and the corresponding
exterior turn signal lamps will flash. Turn signals can be acti -
vated when the multifunction lever is moved down (left) or
up (right).
NOTE:
• A continuous chime will sound if the vehicle is driven more than 1 mile (1.6 km) with either turn signal on.
• Check for an inoperative outside light bulb if either indi -
cator flashes at a rapid rate. • If equipped with fog lamps, the fog lamp on the side of the
activated turn signal will also illuminate to provide addi -
tional light when turning.
— Cruise Control Set Indicator Light — If Equipped
This indicator light will illuminate when the cruise control is
set to the desired speed. Refer to “Speed Control” in
“Starting And Operating” for further information.
White Indicator Lights
— Adaptive Cruise Control (ACC) Ready Light — If
Equipped
This light will illuminate when the vehicle equipped with
Adaptive Cruise Control (ACC) has been turned on but not
set.
Refer to “Adaptive Cruise Control (ACC) — If Equipped” in
“Starting And Operating” for further information.
— Cruise Control Ready Indicator
This indicator light will illuminate when the cruise control is
ready, but not set. Refer to “Speed Control” in “Starting And
Operating” for further information.

160 GETTING TO KNOW YOUR INSTRUMENT PANEL
NOTE:
If you crank or start the engine, you will have to start this test
over.
2. As soon as you cycle the ignition switch to the ON posi-
tion, you will see the “Malfunction Indicator Light (MIL)”
symbol come on as part of a normal bulb check.
3. Approximately 15 seconds later, one of two things will happen:

• The MIL will flash for about ten seconds and then return to being fully illuminated until you turn OFF the ignition or
start the engine. This means that your vehicle's OBD II
system is not ready and you should not proceed to the I/M
station.

• The MIL will not flash at all and will remain fully illumi -
nated until you place the ignition in the off position or start
the engine. This means that your vehicle's OBD II system
is ready and you can proceed to the I/M station. If your OBD II system is
not ready, you should see an autho -
rized dealer or repair facility. If your vehicle was recently
serviced or had a battery failure or replacement, you may
need to do nothing more than drive your vehicle as you
normally would in order for your OBD II system to update.
A recheck with the above test routine may then indicate that
the system is now ready.
Regardless of whether your vehicle's OBD II system is ready
or not, if the MIL is illuminated during normal vehicle oper -
ation you should have your vehicle serviced before going to
the I/M station. The I/M station can fail your vehicle
because the MIL is on with the engine running.
