GETTING TO KNOW YOUR VEHICLE17
NOTE:
If the vehicle is equipped with the Auto Relock feature,
and is unlocked with the key fob, and no door is opened
within 60 seconds, the vehicle will relock and the
Vehicle Security system will arm (if equipped). This
feature can be enabled/disabled within Uconnect
Settings.
 If one or more doors are open, or the liftgate is open,
the doors will lock. The doors will unlock again auto -
matically if the key fob is left inside the passenger
compartment, otherwise the doors will stay locked.
All doors can be programmed to unlock on the first push
of the unlock button through Uconnect Settings
Úpage 197.
Using The Panic Feature
To turn the Panic feature on or off, push the Panic button
on the key fob. When the Panic feature is activated, the
turn signals will flash, the horn may pulse on and off (if
equipped with horn alarm), and the interior lights will turn
on.
The Panic feature will stay on for three minutes unless you
turn it off by either pushing the Panic button a second time
or drive the vehicle at a speed of 15 mph (24 km/h) or
greater.
NOTE:
 The interior lights will turn off if you place the ignition in
the ON/RUN position while the Panic feature is acti -
vated. However, the exterior lights and horn (if
equipped with horn alarm) will remain on. 
You may need to be closer than 66 ft (20 m) from the
vehicle when using the key fob to turn off the Panic
feature due to the radio frequency noises emitted by
the system.
Key Left Vehicle Feature
If a valid key fob is no longer detected inside the vehicle
while the vehicle’s ignition system is in the ON/RUN or
START position, the message “Key Fob Has Left The
Vehicle” will be shown in the instrument cluster display
along with an interior chime. An exterior audible and visual
alert will also be activated to warn the driver.
The vehicle’s horn will rapidly chirp three times along with
a single flash of the vehicle’s exterior lights.
NOTE:
The doors have to be open and then closed in order for
the vehicle to detect a key fob; the Key Left Vehicle
feature will not activate until all of the doors are closed.
 These alerts will not be activated in situations where
the vehicle’s engine is left running with the key fob
inside.
Air Suspension (Remote Lowering Of The
Vehicle) — If Equipped
For easy entry and loading, your vehicle can be
lowered to Entry/Exit height by pushing the key
fob air suspension button two times. When air
suspension lowering is requested using the key
fob, the vehicle will send a series of chirps and flashes
(when enabled within Uconnect Settings) to alert the
customer that the operation has begun and will continue
these alerts until it successfully lowers. The following conditions must be met for the vehicle to
lower remotely:

The vehicle must not already be in Entry/Exit (Park) ride
height.
 The vehicle battery must be fully charged.
 All doors must be closed.
 The key fob must be out of the vehicle.
NOTE:Ensure the vehicle is clear of all objects, pets, and people
prior to remote lowering.
Canceling Remote Lowering
Vehicle lowering can be canceled at anytime. When
vehicle lowering is canceled, the vehicle will raise up to the
next defined level and lock out the remote lowering
feature for five seconds before a new request can be
made.
To cancel vehicle lowering, push the key fob air
suspension button one time during the lowering process.
When vehicle lowering is canceled, the horn will chirp two
times and the turn signals will flash four times. Once
raising is completed, the horn will chirp one time.
NOTE:For more information on Air Suspension, see Úpage 132.

Key Fob Battery Location

NOTE:You can also insert a screwdriver or similar tool into the
battery removal pocket to pry the battery out.

Battery Removal Pocket

NOTE:When replacing the battery, ensure the (+) sign on the
battery is facing upward. Avoid touching the new battery
with your fingers. Skin oils may cause battery deterio -
ration. If you touch a battery, clean it with rubbing alcohol.
5. Replace the battery by using your thumb to push down and slide the battery under the small lip on the
top edge of the opening.

Key Fob Battery Replacement

6. To assemble the key fob case, line up the top edge of the back cover with the top of the fob, and press the
edges into the interlocking hinges until all edges snap
together with no large visual gaps.
7. Reinsert the emergency key until it locks into place.
NOTE:The key fob battery should only be replaced by qualified
technicians. If the battery requires replacement, see an
authorized dealer.
WARNING!
 The integrated key fob contains a coin cell battery.
Do not ingest the battery; there is a chemical burn
hazard. If the coin cell battery is swallowed, it can
cause severe internal burns in just two hours and
can lead to death.
 If you think a battery may have been swallowed or
placed inside any part of the body, seek immediate
medical attention.
 Keep new and used batteries away from children.
If the battery compartment does not close securely,
stop using the product and keep it away from chil -
dren.

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.

23_WS_OM_EN_USC_t.book Page 20

22GETTING TO KNOW YOUR VEHICLE
NOTE:
The key fob may not be detected by the vehicle Keyless
Enter ‘n Go™ system if it is located next to a mobile
phone, laptop or other electronic device; these devices
may block the key fob’s wireless signal and prevent the
Keyless Enter ‘n Go™ system from starting the vehicle.
 For more information on the engine starting procedure,
see
Úpage 119.
 When opening the driver's door and the ignition is in
the ON/RUN position (engine not running), a chime will
sound to remind you to place the ignition in the OFF
position. In addition to the chime, the message “Igni-
tion ON” will display in the cluster.
REMOTE START
This system uses the key fob to start the engine
conveniently from outside the vehicle while still
maintaining security. The system has a range
of approximately 328 ft (100 m).
Remote Start is used to defrost windows in cold weather,
and to reach a comfortable climate in all ambient
conditions before the driver enters the vehicle.
NOTE:Obstructions between the vehicle and key fob may reduce
this range Úpage 382.
HOW TO USE REMOTE START
Push and release the Remote Start button on the key fob
twice within five seconds. The vehicle doors will lock, the
parking lights will flash, and the horn will chirp twice (if
programmed). Then, the engine will start, and the vehicle
will remain in the Remote Start mode for a 15 minute
cycle. Pushing the Remote Start button a third time shuts
the engine off.
NOTE:
 With Remote Start, the engine will only run for
15 minutes.
 Remote Start can only be used twice.
 If an engine fault is present or fuel level is low, the
vehicle will start and then shut down in 10 seconds.
 The parking lights will turn on and remain on during
Remote Start mode. 
Headlight animation (if equipped) will occur when
Remote Start is activated, if “Headlight Illumination On
Approach” is enabled within Uconnect Settings.
 For security, power window and power sunroof opera -
tion (if equipped) are disabled when the vehicle is in
the Remote Start mode.
 The ignition must be placed in the ON/RUN position
before the Remote Start sequence can be repeated for
a third cycle.
All of the following conditions must be met before the
engine will remote start:
 Gear selector in PARK
 Doors closed
 Hood closed
 Liftgate closed
 Hazard switch off
 Brake switch inactive (brake pedal not pressed)
 Battery at an acceptable charge level
 System not disabled from previous Remote Start event
 Vehicle Security Light flashing
 Ignition in OFF position
 Panic button is not pushed
 Fuel level meets minimum requirement
 Vehicle Security system is not signaling an intrusion
 Malfunction Indicator Light (MIL) is not illuminated
WARNING!
Do not start or run an engine in a closed garage or
confined area. Exhaust gas contains carbon
monoxide which is odorless and colorless. Carbon
monoxide is poisonous and can cause serious injury
or death when inhaled.
 Keep key fobs away from children. Operation of the
Remote Start system, windows, door locks or other
controls could cause serious injury or death.
