WARNING!(Continued)
•Do not leave children or animals inside parked
vehicles in hot weather. Interior heat build-up may
cause serious injury or death.
CAUTION!
An unlocked car is an invitation to thieves. Always
remove the Key Fob from vehicle, cycle the ignition
OFF and lock all doors when leaving the vehicle
unattended.
SENTRY KEY®
The Sentry Key® Immobilizer system prevents unauthor-
ized 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 with a factory-mated Remote
Keyless Entry (RKE) transmitter, a Keyless Ignition Node
(KIN) and a RF receiver to prevent unauthorized vehicle
operation. Therefore, only Key Fobs that are pro-
grammed to the vehicle can be used to start and operate
the vehicle. The system will not allow the engine to crank
if an invalid Key Fob is used to start and operate the
vehicle. The system will shut the engine off in two
seconds if an invalid Key Fob is used to start the engine.
After placing the ignition 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
addition, if the light begins to flash after the bulb check,
it indicates that someone used an invalid Key Fob to start
the engine. Either of these conditions will result in the
engine being shut off after two seconds.
2
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 17

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 electron-
ics. Should this occur, have the vehicle serviced as soon
as possible by an authorized dealer.
CAUTION!
•Do not make modifications or alterations to the
immobilizer system. Modifications or alterations to
the immobilization system may result in a loss of
security protection.
• The Sentry Key® Immobilizer system is not com-
patible with some aftermarket remote starting sys-
tems. Use of these systems may result in vehicle
starting problems and loss of security protection.
All of the Key Fobs provided with your new vehicle have
been programmed to the vehicle electronics.
Replacement Keys
NOTE: Only Key Fobs that are programmed to the
vehicle electronics can be used to start and operate the
vehicle. Once a Key Fob is programmed to a vehicle, it
cannot be programmed to any other vehicle.
CAUTION!
• Always remove the Key Fobs from the vehicle and
lock all doors when leaving the vehicle unat-
tended.
• For vehicles equipped with Keyless Enter-N-Go™,
always remember to place the ignition in the OFF
position.
At the time of purchase, the original owner is provided
with a four-digit Personal Identification Number (PIN).
Keep the PIN in a secure location. This number is
required for authorized dealer replacement of Key Fobs.
18 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

REMOTE STARTING SYSTEM — IF EQUIPPED
This system uses the Remote Keyless Entry
(RKE) transmitter to start the engine conve-
niently from outside the vehicle while still
maintaining security. The system has a range of
approximately 300 ft (91 m).
NOTE:
• The vehicle must be equipped with an automatic
transmission to be equipped with Remote Start.
• Obstructions between the vehicle and the RKE trans-
mitter may reduce this range.
How To Use Remote Start
All of the following conditions must be met before the
engine will remote start:
• Shift lever in PARK
• Doors closed
• Hood closed
• HAZARD switch off
• BRAKE switch inactive (brake pedal not pressed)
• Battery at an acceptable charge level
• RKE PANIC button not pressed
• Fuel meets minimum requirement
• System not disabled from previous remote start event
• Vehicle security alarm not active
20 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

•If an engine fault is present or fuel level is low, the
vehicle will start and then shut down in 10 seconds.
• The park lamps will turn on and remain on during
Remote Start mode.
• For security, power window and power sunroof op-
eration (if equipped) are disabled when the vehicle is
in the Remote Start mode.
• The engine can be started two consecutive times (two
15-minute cycles) with the RKE transmitter. However,
the ignition switch must be cycled to the ON/RUN
position before you can repeat the start sequence for a
third cycle.
To Exit Remote Start Mode Without Driving The
Vehicle
Press and release the REMOTE START button one time or
allow the engine to run for the entire 15-minute cycle. NOTE:
To avoid unintentional shut downs, the system
will disable the one time press of the REMOTE START
button for two seconds after receiving a valid Remote
Start request.
To Exit Remote Start Mode And Drive The Vehicle
Before the end of the 15-minute cycle, press and release
the UNLOCK button on the RKE transmitter to unlock
the doors and disarm the Vehicle Security Alarm System
(if equipped). Then, prior to the end of the 15 minute
cycle, cycle the ignition to the ON/RUN position.
Remote Start Comfort Systems — If Equipped
When remote start is activated, the heated steering
wheel, and driver heated seat features will automatically
turn on in cold weather. In warm weather, the driver
vented seat feature will automatically turn on when the
remote start is activated. These features will stay on
through the duration of remote start or until the ignition
switch is turned to the ON/RUN position.
22 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

The Remote Start Comfort System can be activated and
deactivated through the Uconnect® system. For more
information on Remote Start Comfort System operation
refer to “Uconnect® Settings” in “Understanding Your
Instrument Panel”.
VEHICLE SECURITY ALARM — IF EQUIPPED
This Vehicle Security Alarm monitors the vehicle doors,
liftgate, and ignition for unauthorized operation. When
the alarm is activated, the interior switches for door
locks, and power liftgate are disabled. The Vehicle Secu-
rity Alarm provides both audio and visual signals, the
horn will sound, the headlights will turn on, park lamps
and/or turn signals will flash repeatedly for three min-
utes. If the disturbance is still present (driver’s door,
passenger door, other doors, ignition) after three minutes,
the headlights, park lamps and/or turn signals will flash
for an additional 15 minutes.NOTE:
The Panic and Security alarms are quite different.
Please take a moment to activate the Panic and the
Security modes to hear the differences in the horn. In case
one should go off in the future, you will need to know
which mode has been activated in order to deactivate it.
Rearming The System
If something triggers the alarm, and no action is taken to
disarm it, the Vehicle Security Alarm will turn off the
horn after three minutes, turn off all of the visual signals
after 15 minutes, and then the Vehicle Security Alarm will
rearm itself.
To Arm The System
Follow these steps to arm the Vehicle Security Alarm:
1. Make sure the vehicles ignition is cycled to the “OFF” position (refer to Starting Procedures inStarting
And Operating for further information).

24 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

not disarm the Vehicle Security Alarm. If someone
enters the vehicle through the liftgate and opens any
door the alarm will sound.
• When the Vehicle Security Alarm is armed, the interior
power door lock switches will not unlock the doors.
The Vehicle Security Alarm is designed to protect your
vehicle; however, you can create conditions where the
system will give you a false alarm. If one of the previ-
ously described arming sequences has occurred, the
Vehicle Security Alarm will arm regardless of whether
you are in the vehicle or not. If you remain in the vehicle
and open a door, the alarm will sound. If this occurs,
disarm the Vehicle Security Alarm.
If the Vehicle Security Alarm is armed and the battery
becomes disconnected, the Vehicle Security Alarm will
remain armed when the battery is reconnected; the
exterior lights will flash, the horn will sound. If this
occurs, disarm the Vehicle Security Alarm.Tamper Alert
If something has triggered the Vehicle Security Alarm in
your absence, the horn will sound three times and the
exterior lights blink three times when you unlock the
doors. Check the vehicle for tampering.
ILLUMINATED ENTRY — IF EQUIPPED
The courtesy lights will turn on when you use the
Remote Keyless Entry (RKE) transmitter to unlock the
doors or open any door.
This feature also turns on the approach lighting in the
outside mirrors (if equipped). Refer to “Mirrors” in
“Understanding The Features Of Your Vehicle” for fur-
ther information.
The lights will fade to off after approximately 30 seconds
or they will immediately fade to off once the ignition is
cycled to the ON/RUN position from the OFF position.
