Programming And Requesting Additional
Key Fobs
Programming the key fob may be performed by an
authorized dealer.
NOTE:
Once a key fob is programmed to a vehicle, it cannot be
repurposed and reprogrammed to another vehicle.
 Only key fobs that are programmed to the vehicle elec -
tronics can be used to start and operate the vehicle.
Duplication of key fobs may be performed at an authorized
dealer. This procedure consists of programming a blank
key fob to the vehicle electronics. A blank key fob is one
that has never been programmed.
NOTE:
 When having the Sentry Key Immobilizer system
serviced, bring all vehicle keys with you to an autho -
rized dealer.
 Keys must be ordered to the correct key cut to match
the vehicle locks.
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 Radio Frequency (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 placing the ignition in 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
addition, if the light begins to flash after the bulb check, it
indicates 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
electronics, the engine will start and shut off after two
seconds.
If the Vehicle Security Light turns on during normal vehicle
operation (vehicle running for longer than 10 seconds), it
indicates that there is a fault in the electronics. Should
this occur, have the vehicle serviced as soon as possible
by an authorized dealer. All of the key fobs provided with your new vehicle have
been programmed to the vehicle electronics
Úpage 382.
NOTE:A key fob that has not been programmed is also
considered an invalid key.
IGNITION SWITCH
KEYLESS ENTER ‘N GO™ IGNITION
This feature allows the driver to operate the ignition switch
with the push of a button as long as the key fob is in the
passenger compartment.
The START/STOP ignition button has several operating
modes that are labeled and will illuminate when in
position. These modes are OFF, ON/RUN, and START.
WARNING!

Always remove the key fobs from the vehicle and lock
all doors when leaving the vehicle unattended.
 For vehicles equipped with Keyless Enter ‘n Go™ Igni -
tion, always remember to place the ignition in the
OFF position when exiting the vehicle.
CAUTION!
The Sentry Key Immobilizer system is not compatible
with some aftermarket Remote Start systems. Use of
these systems may result in vehicle starting problems
and loss of security protection.

illuminate when the fog lights are on. The fog lights will
turn off when the button is pushed a second time, when
the headlight switch is rotated to the off position, or the
high beam is selected.
Cornering Lights
The cornering lights are a feature to improve visibility at
night while turning the vehicle. When activated, a light
incorporated in the front fog light will illuminate on the
side of the vehicle the steering wheel is rotated or the turn
signal indicator is on. It can be activated through the
Uconnect system
Úpage 197.
TURN SIGNALS
Move the multifunction lever up or down and the arrows
on each side of the instrument cluster will flash to show

bulb.
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.
BATTERY SAVER
To protect the life of your vehicle’s battery, load shedding
is provided for both the interior and exterior lights.
If the ignition is placed in the OFF position and any door is
left ajar for 10 minutes or if the overhead console Dome
ON switch is pressed, and the interior lights are on for
10 minutes, the interior lights will automatically turn off.
NOTE:Battery saver mode is canceled if the ignition is in the
ON position.
If the headlights remain on while the ignition is placed in
the OFF position, the exterior lights will automatically turn
off after eight minutes. If the headlights are turned on and
left on for eight minutes while the ignition is in the OFF
position, the exterior lights will automatically turn off.
INTERIOR LIGHTS
COURTESY LIGHTS
Courtesy and dome lights are turned on when the front
doors are opened or the Dome ON button is pushed on the
overhead console. If your vehicle is equipped with Remote
Keyless Entry and the unlock button is pushed on the key
fob, the courtesy and dome lights will turn on. When a door
is open and the interior lights are on, pressing the Dome
Defeat button on the overhead console will cause all of the
interior lights to turn off. This allows the doors to stay open
for extended periods of time without discharging the
vehicle’s battery.

RED WARNING LIGHTS
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 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 ABS pump will run when applying the brake,
and a brake pedal pulsation may be felt during each stop. The dual brake system provides a reserve braking capacity
in the event of a failure to a portion of the hydraulic
system. A leak in either half of the dual brake system is
indicated by the Brake Warning Light, which will turn on
when the brake fluid level in the master cylinder has
dropped below a specified level.
The light will remain on until the cause is corrected.
NOTE:The light may flash momentarily during sharp cornering
maneuvers, which change fluid level conditions. The
vehicle should have service performed, and the brake
fluid level checked.
If brake failure is indicated, immediate repair is necessary.
Vehicles equipped with the Anti-Lock Brake System (ABS)
are also equipped with Electronic Brake Force Distribution
(EBD). In the event of an EBD failure, the Brake Warning
Light will turn on along with the ABS Light. Immediate
repair to the ABS system is required.
Operation of the Brake Warning Light can be checked by
turning the ignition switch from the OFF position to the
ON/RUN position. The light should illuminate for
approximately two seconds. The light should then turn off
unless the parking brake is applied or a brake fault is
detected. If the light does not illuminate, have the light
inspected by an authorized dealer.The light also will turn on when the parking brake is
applied with the ignition switch in the ON/RUN position.
NOTE:This light shows only that the parking brake is applied. It
does not show the degree of brake application.
Battery Charge Warning Light
This warning light will illuminate when the
battery is not charging properly. If it stays on
while the engine is running, there may be a
malfunction with the charging system. Contact
an authorized dealer as soon as possible.
This indicates a possible problem with the electrical
system or a related component.
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.
WARNING!
Driving a vehicle with the red brake light on is
dangerous. Part of the brake system may have failed. It
will take longer to stop the vehicle. You could have a
collision. Have the vehicle checked immediately.

ONBOARD DIAGNOSTIC SYSTEM
(OBD II) C
YBERSECURITY
Your vehicle is required to have 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
Úpage 196.
EMISSIONS INSPECTION AND
MAINTENANCE PROGRAMS
In some localities, it may be a legal requirement to pass an
inspection of your vehicle's emissions control system.
Failure to pass could prevent vehicle registration.
For states that require an Inspection and
Maintenance (I/M), this check verifies the
Malfunction Indicator Light (MIL) is functioning
and is not on when the engine is running, and
that the OBD II system is ready for testing.
Normally, the OBD II system will be ready. The OBD II
system may not be ready if your vehicle was recently
serviced, recently had a depleted battery or a battery
replacement. If the OBD II system should be determined
not ready for the I/M test, your vehicle may fail the test.
Your vehicle has a simple ignition actuated test, which you
can use prior to going to the test station. To check if your
vehicle's OBD II system is ready, you must do the following:

1. Cycle the ignition switch to the ON position, but do not crank or start the engine.

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 position, 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 10 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 illu -
minated until you place the ignition in the off posi -
tion 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
authorized 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 previously mentioned 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
operation 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.
WARNING!
 ONLY an authorized service technician should
connect equipment to the OBD II connection port in
order to read the VIN, diagnose, or service your
vehicle.
 If unauthorized equipment is connected to the OBD II
connection port, such as a driver-behavior tracking
device, it may:
 Be possible that vehicle systems, including
safety related systems, could be impaired or a
loss of vehicle control could occur that may
result in an accident involving serious injury or
death.
 Access, or allow others to access, information
stored in your vehicle systems, including
personal information.
