KEYS
Key Fob
Your vehicle uses a keyless ignition system. The
ignition system consists of a key fob with
Remote Keyless Entry (RKE) and a START/STOP
push button ignition system. The Remote
Keyless Entry (RKE) system (if equipped)
consists of a key fob and Keyless Enter-N-Go
feature.
NOTE:
The key fob may not be found if it is located next
to a mobile phone, laptop or other electronic
device; these devices may block the key fob’s
wireless signal.
If the vehicle is equipped with remote power
door locks, the key fob allows you to lock or
unlock all doors, as well as activate the Panic
Alarm, 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. NOTE:
In the ON/RUN position, all key fob buttons
will work until the vehicle reaches 2 mph
(4 km/h).
The key fob should not be placed next to the
wireless charging pad (if equipped).

Key Fob
In case the ignition switch does not change with
the push of a button, the key fob may have a low
or fully depleted battery. A low key fob battery
can be verified by referring to the instrument
cluster, which will display directions to follow.
In a situation where the battery is low or fully
depleted, a back up method can be used to
operate the ignition switch. Put the nose side of
the key fob (side opposite of the emergency key)
against the START/STOP ignition button and
push to operate the ignition switch.
To Unlock The Doors
If the vehicle is equipped with remote power
door locks, push and release the unlock button
on the key fob once to unlock the driver’s door.
Push the unlock button twice within five
seconds to unlock all doors. The turn signal
lights will flash to acknowledge the unlock
signal. The illuminated entry system will also
turn on.
NOTE:
All doors can be programmed to unlock on the
first push of the unlock button. Refer to
“Uconnect Settings” in “Multimedia” for further
information.

14GETTING TO KNOW YOUR VEHICLE
To Lock The Doors
If the vehicle is equipped with remote power
door locks, push and release the lock button on
the key fob to lock all doors. The turn signal
lights will flash and the horn will chirp to
acknowledge the signal.
Sound Horn With Remote Key Lock
This feature will cause the horn to chirp when
the doors are locked with the key fob. This
feature can be turned on or turned off.
NOTE:
Pushing the lock button on the key fob while you
are in the vehicle will activate the vehicle secu -
rity alarm system. Opening a door with the
vehicle security alarm system activated will
cause the alarm to sound. Push the unlock
button to deactivate the vehicle security alarm
system.
Refer to “Instrument Cluster Display” in
“Getting To Know Your Instrument Panel” for
further information.
Using The Panic Alarm
To turn the Panic Alarm feature on or off, push
the Panic button on the key fob. When the Panic
Alarm is activated, the turn signals will flash, the
horn will pulse on and off, and the interior lights
will turn on.
The Panic Alarm will stay on for three minutes
unless you turn it off by either pushing the Panic
button a second time or driving 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 ACC or ON/RUN position while
the Panic Alarm is activated. However, the
exterior lights and horn will remain on.
You may need to be less than 35 ft (11 m)
from the vehicle when using the key fob to
turn off the Panic Alarm due to the radio
frequency noises emitted by the system.
Replacing The Battery In The Key Fob With
Remote Control
The replacement battery model is one CR2032
battery. NOTE:
Perchlorate Material — special handling may
apply. See
www.dtsc.ca.gov/hazard -
ouswaste/perchlorate for further informa -
tion.
Do not touch the battery terminals that are
on the back housing or the printed circuit
board.

1. Remove the emergency key by pushing and holding the release button located on

IGNITION SWITCH
Keyless Push Button Ignition
This feature allows the driver to operate the igni -
tion switch with the push of a button as long as
the Remote Keyless Entry key fob is in the
passenger compartment.
The Keyless Push Button Ignition has four oper -
ating positions; three of which are labeled and
will illuminate when in position. The three posi -
tions are OFF, ACC, and ON/RUN. The fourth
position is START. During START, RUN will illumi -
nate.
NOTE:
In case the ignition switch does not change with
the push of a button, the key fob may have a low
or depleted battery. In this situation, a back up
method can be used to operate the ignition
switch. Put the nose side (side opposite of the
emergency key) of the key fob against the
START/STOP ignition button, with your foot
applied on the brake pedal, and push to operate
the ignition switch.
Keyless Push Button Ignition

The push button ignition can be placed in the
following modes:
OFF
The engine is stopped.
Some electrical devices (e.g. Central locking,
alarm, etc.) are still available.
ACC
Engine is not started.
Some electrical devices are available. RUN

Driving position.
All the electrical devices are available.
START
The engine will start.
1 — OFF
2 — ACC (Accessory)
3 — ON/RUN
WARNING!
When exiting the vehicle, always remove
the key fob from the vehicle and lock your
vehicle.
Never leave children alone in a vehicle, or
with access to an unlocked vehicle.
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, and do not leave the ignition of a
vehicle equipped with Keyless Enter-N-Go
in the ON/RUN mode. A child could operate
power windows, other controls, or move the
vehicle.

18GETTING TO KNOW YOUR VEHICLE
The engine only runs when the ignition is in the
ON/RUN position, or from a remote start
request.
In case the ignition switch does not change with
the push of a button, the key fob may have a low
or depleted battery. In this situation, a back up
method can be used to operate the ignition
switch. Put the nose side (side opposite of the
emergency key) of the key fob against the
START/STOP ignition button and push to
operate the ignition switch.
Back Up Starting Method

NOTE:
The key fob may not be able to be detected by
the vehicle keyless-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-go
system from starting the vehicle.
NOTE:
Refer to "Starting The Engine" in "Starting And
Operating" for further information.
REMOTE START — IF EQUIPPED
(GASOLINE)
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 300 ft (91 m).
NOTE:
Obstructions between the vehicle and the key
fob may reduce this range.
How To Use Remote Start
All of the following conditions must be met
before the engine will remote start:
Gear selector in PARK
Doors closed
Hood closed
Hazard switch off
Brake switch inactive (brake pedal not
pushed)
Battery at an acceptable charge level
PANIC button not pushed
Fuel meets minimum requirement
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 for
thieves. Always remove key fob from the
vehicle and lock all doors when leaving the
vehicle unattended.
