GETTING TO KNOW YOUR VEHICLE
KEYS
KEY FOB
Your vehicle uses a key start ignition system
which supports Remote Keyless Entry (RKE).
The key fob allows you to lock or unlock the
doors from distances up to approximately 66 ft
(20 m). The key fob does not need to be pointed
at the vehicle to activate the system. The key
fob also contains an integrated mechanical key,
which can be used by pushing the mechanical
key release button.
The vehicle is supplied with a code card
containing key code numbers to order duplicate
keys, and the authorized dealer that sold you
your new vehicle has the key code numbers for
your vehicle locks. These numbers can be used
to order duplicate keys.
NOTE:
The key fob may not be able to be detected by
the vehicle if it is located next to a mobile
phone, laptop or other electronic device; these
devices may block the key fob’s wireless signal
Úpage 274.
Key Fob With Integrated Mechanical Key

To Lock/Unlock The Doors
To lock all of the doors, push and release the
lock button once. Push and release the unlock
button on key fob once to unlock only the front
doors. Push and release the cargo unlock
button on key fob once to unlock the cargo area
(rear lateral sliding doors and rear door). The
doors can also be locked and unlocked
manually by using the mechanical key.
When the doors are unlocked, the turn signals
will flash. When the doors are locked, the turn
signals will flash and the horn will chirp (if
activated through the Uconnect Settings
Ú
page 89). If a door is open when the lock
button is pushed, the turn signal lights will flash
at an increased rate to indicate that a door is
still open.

GETTING TO KNOW YOUR VEHICLE13
NOTE:
Opening the driver's door when the key is in the
ignition and the ignition switch position is STOP
(OFF/LOCK) sounds a signal to remove the key.
VEHICLE SECURITY SYSTEM — IF EQUIPPED
The Vehicle Security system monitors the
vehicle doors and ignition for unauthorized
operation. When the Vehicle Security system is
activated, interior switches for door locks are
disabled. The system provides both audible and
visible signals. For the first three minutes, the
horn will sound, and the turn signal lights will
flash. For an additional 15 minutes, only the
turn signal lights will flash.
TO ARM THE SYSTEM
To arm the system, the Vehicle Security system
will set when you use the key fob to lock the
doors. If a door or the hood is not properly shut,
the system will not be armed.
TO DISARM THE SYSTEM
Use the key fob to unlock the door and disarm
the system.
The Vehicle Security system will also disarm if a
programmed Sentry Key is inserted into the
ignition switch. To exit the alarming mode,
push the key fob unlock button, or insert a
programmed Sentry Key into the ignition switch. The Vehicle Security system is designed to
protect your vehicle. However, you can create
conditions where the system will give you a false
alarm. If one of the previously described arming
sequences has occurred, the Vehicle Security
system 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 system.
REARMING OF THE SYSTEM
If the system has not been disabled, the Vehicle
Security system will rearm itself after the 15
additional minutes of turn lamps flashing. If the
condition which initiated the alarm is still
present, the system will ignore that condition
and monitor the remaining doors and ignition.
SECURITY SYSTEM MANUAL OVERRIDE
The Vehicle Security system will not arm/disarm
if you lock/unlock the doors using the manual
door lock.
Allowing children to be in a vehicle unat
-
tended is dangerous for a number of
reasons. A child or others could be seriously
or fatally injured. Children should be
warned not to touch the parking brake,
brake pedal or the gear selector.
Do not leave the key fob in or near the
vehicle, or in a location accessible to chil-
dren. A child could operate power windows,
other controls, or move the vehicle.
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 vehicle is an invitation. Always
remove the key from the ignition and lock all
the doors when leaving the vehicle unattended.

EXTERIOR LIGHTS
MULTIFUNCTION LEVER
The multifunction lever controls the operation
of the headlights, parking lights, turn signals,
headlight beam selection and the passing
lights. The multifunction lever is located on the
left side of the steering column.

Multifunction Lever

HEADLIGHTS
To turn on the headlights, turn the end of the
multifunction lever to the headlight position.
When the headlight switch is on, the parking
lights, taillights, license plate light, clearance
lights and instrument panel lights are also turned on. To turn off the headlights, turn the
end of the multifunction lever back to the O (off)
position.
DAYTIME RUNNING LIGHTS (DRLS) — IF
E
QUIPPED
NOTE:
When the headlights are turned on, the Daytime
Running Lights will be deactivated.
To activate the Daytime Running Lights, rotate
the end of the multifunction lever to the O (off)
position.
For vehicles sold in Canada, the Daytime
Running Lights will automatically deactivate
when the front fog lights are turned on. When
the end of the multifunction lever is turned to
the O (off) position with the DRLs on, the
parking lights and license plate lights will also
turn on.
NOTE:
The low beams and side/taillights will not be on
with DRLs.
The Daytime Running Lights will come on
whenever the ignition is ON, the headlight
switch is off, and the turn signal is off.
HIGH/LOW BEAM SWITCH
With the low beams activated, pull the
multifunction lever toward the steering wheel to
turn on the high beams. The High Beam
Indicator Light will illuminate in the instrument
cluster to indicated that the high beams are on.
Pull the multifunction lever a second time to
switch the headlights back to low beam. When
the ignition is placed in the OFF position, both
the high and low beams will turn off.
FLASH-TO-PASS
You can signal another vehicle with your
headlights by lightly pulling the multifunction
lever toward you. This will cause the high beam
headlights to turn on, and remain on, until the
lever is released.
PARKING LIGHTS
These lights can be turned on, with the ignition
key in the STOP (OFF/LOCK) position or
removed, by moving the end of the
multifunction lever to O (off) position and then
to the headlight position.
The indicator light in the instrument panel
comes on. The lights stay on until the next
ignition cycle is performed.

GETTING TO KNOW YOUR VEHICLE27
FOLLOW ME HOME/HEADLIGHT DELAY
When this feature is selected, the driver can
choose to have the headlights remain on for a
preset period of time after the engine is turned
off.
Activation
Remove the key or turn the ignition to the STOP
(OFF/LOCK) position, and pull the multifunction
lever toward the steering wheel within two
minutes. Each time the lever is pulled, the
activation of the lights will be extended by
30 seconds. The activation of the lights can be
extended to a maximum of 210 seconds.
The indicator light on the instrument panel will
light up and the corresponding message will
appear in the instrument cluster display for as
long as the function is activated. The indicator
light comes on when the lever is operated and
stays on until the function is automatically
deactivated. Each movement of the lever only
increases the amount of time the lights stay on.

Pull the multifunction lever toward the steering
wheel and hold it for more than two seconds.

lights on. Push the switch a second
time to turn the fog lights off.
NOTE:
If the vehicle’s ignition is turned off, the fog
lights will also turn off.

the arrows on each side of the instrument
cluster will flash to show proper operation of the
turn signals.

without moving beyond the detent, and the turn
signal will flash five times then automatically
turn off.
