NOTE:
If the vehicle is unlocked by key fob, and no
door is opened within 60 seconds, the vehicle
will re-lock and if equipped, the security
alarm will arm. To change the current setting,
refer to "Uconnect Settings" in "Multimedia"
in the Owner’s Manual for further informa-
tion.
To Lock The Doors And Liftgate
Push and release the lock button on the key
fob to lock all doors and liftgate.
Vehicles Equipped With Keyless Enter-N-Go —
Passive Entry
If one or more doors are open, or the liftgate is
open, the doors will lock. The doors will
unlock again automatically if the key is left
inside the passenger compartment, otherwise
the doors will stay locked.
Request For Additional Key Fobs
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 pro-
grammed to a vehicle, it cannot be pro-
grammed to any other vehicle.
WARNING!
• Always remove the key fobs from thevehicle and lock all doors when leaving
the vehicle unattended.
• For vehicles equipped with Keyless
Enter-N-Go — Ignition, always remem-
ber to place the ignition in the OFF
mode.
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 Sys-
tem serviced, bring all vehicle keys with you
to an authorized dealer.
IGNITION SWITCH
Ignition Node Module (IGNM) —
If Equipped
The Ignition Node Module (IGNM) operates
similar to an ignition switch. It has four
operating positions, three with detents and
one that is spring-loaded. The detent posi-
tions are OFF, ACC, and ON/RUN. The START
position is a spring-loaded momentary con-
tact position. When released from the START
position, the switch automatically returns to
the ON/RUN position.
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 com-
partment.
The push button ignition operating modes are
OFF, ACC, RUN, and START.
15

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.
NOTE:
For further information, refer to "Starting The
Engine" in "Starting And Operating."
Electronic Steering Wheel Lock —
If Equipped
Your vehicle may be equipped with a passive
electronic steering wheel lock. This lock pre-
vents steering the vehicle with the ignition
OFF. The steering wheel lock releases with
the ignition ON. If the lock does not disen-
gage and the vehicle does not start, turn the
wheel to the left and right to disengage the
lock.
REMOTE STARTING
SYSTEM — IF EQUIPPED
Push the remote start button on the key fob
twice within five seconds. Pushing the re-
mote start button a third time shuts the
engine off.
To drive the vehicle, push the START/STOP
button to turn the ignition to the ON/RUN
mode.
NOTE:
• With remote start, the engine will only run for 15 minutes (timeout) unless the igni-
tion is placed in the ON/RUN mode.
• The vehicle must be started with the key after two consecutive timeouts.
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.
CAUTION!
The Sentry Key Immobilizer system is not
compatible with some aftermarket remote
starting systems. 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.
Irregular Operation
The system uses a key fob, an Ignition Node
Module, Keyless Push Button Ignition and a
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 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.
NOTE:
A key fob that has not been programmed is
also considered an invalid key.
17

During normal operation, after placing the
keyless ignition in the ON/RUN mode, 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 try to start the engine.
Either of these conditions will result in the
engine being 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.
VEHICLE SECURITY ALARM
— IF EQUIPPED
This vehicle security alarm monitors the ve-
hicle doors, hood, liftgate, and ignition for
unauthorized operation. While the vehicle
security alarm is armed, interior switches for
door locks and liftgate release are disabled. If
something triggers the vehicle securityalarm, the horn will sound for 29 seconds
and turn off all of the visual signals after an
additional 31 seconds. If the triggering de-
vice is not deactivated, the horn will sound
again after a five second delay for another
29 seconds. If the trigger remains present,
this cycle will repeat for up to five minutes.
To Arm The System
Follow these steps to arm the vehicle security
alarm:
1. Make sure the vehicle’s ignition is placed
in the “OFF” mode.
• For vehicles equipped with Keyless En- try, make sure the vehicle’s keyless
ignition system is OFF.
2. Perform one of the following methods to lock the vehicle:
• Push the lock button on the interior power door lock switch with the driver
and/or passenger door open.
• Push the lock button on the exterior Passive Entry Door Handle with a valid
key fob available in the same exterior zone. Refer to "Doors" in "Getting To
Know Your Vehicle" in your Owner’s
Manual for further information.
• Push the lock button on the key fob.
3. If any doors are open, close them.
To Disarm The System
The vehicle security alarm can be disarmed
using any of the following methods:
• Push the unlock button on the key fob.
• Grasp the passive entry door handle to unlock the door, refer to "Doors" in "Getting
To Know Your Vehicle" in your Owner’s
Manual for further information.
• Cycle the ignition out of the off mode to disarm the system.
NOTE:
• The driver's door key cylinder and the lift- gate button on the key fob cannot arm or
disarm the vehicle security alarm.

• The vehicle security alarm remains armedduring power liftgate entry. Pushing the
liftgate button will not disarm the vehicle
security alarm. If someone enters the ve-
hicle 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 previously 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, and the horn will sound. If this occurs,
disarm the vehicle security alarm.DOORS
Keyless Enter-N-Go — Passive Entry
The Passive Entry system is an enhancement
to the vehicle’s Remote Keyless Entry system
and a feature of Keyless Enter-N-Go — Pas-
sive Entry. This feature allows you to lock and
unlock the vehicle’s door(s) and fuel door
without having to push the key fob lock or
unlock buttons.
NOTE:
• Passive Entry may be programmed ON/OFF; refer to “Uconnect Settings” in “Multime-
dia” in the Owner’s Manual for further in-
formation.
• If wearing gloves on your hands, or if it has been raining/snowing on the Passive Entry
door handle, the unlock sensitivity can be
affected, resulting in a slower response
time.
• If the vehicle is unlocked by Passive Entry and no door is opened within 60 seconds,
the vehicle will re-lock and if equipped will
arm the security alarm. • The key fob may not be able to be detected
by the vehicle passive entry 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 pre-
vent the passive entry handle from locking/
unlocking the vehicle.
• Passive Entry activates illuminated ap- proach for the time set by the customer (0,
30, 60, or 90 seconds), and flashes the
turn signal lights. Refer to “Uconnect Set-
tings” in “Multimedia” in the Owner’s
Manual for further information
To Unlock From The Driver's Side
With a valid Passive Entry key fob within 5ft
(1.5m) of the driver's door handle, grab the
front driver door handle to unlock the driver's
door automatically.
19

NOTE:
If “Unlock All Doors 1st Press” is pro-
grammed, all doors will unlock when you grab
hold of the front driver’s door handle. To
select between “Unlock Driver Door 1st
Push” and “Unlock All Doors 1st Press,”
refer to “Uconnect Settings” in “Multime-
dia” in the Owner’s Manual for further infor-
mation.To Unlock From The Passenger Side
With a valid Passive Entry key fob within 5ft
(1.5m) of the passenger door handle, grab
the front passenger door handle to unlock all
four doors and the liftgate automatically.
NOTE:
All doors will unlock when the front passen-
ger door handle is grabbed regardless of the
driver’s door unlock preference setting (“1st
Press of Key Fob Unlocks” or “Unlock All
Doors 1st Press”).
Preventing Inadvertent Locking Of Passive Entry
Key Fob In Vehicle (FOBIK-Safe)
To minimize the possibility of unintentionally
locking a Passive Entry key fob inside your
vehicle, the Passive Entry system is equipped
with an automatic door unlock feature which
will function if the ignition is OFF.
FOBIK-Safe only executes in vehicles with
passive entry. There are three situations that
trigger a FOBIK-Safe search in any passive
entry vehicle:
• A lock request is made by a valid Passive
Entry key fob while a door is open. • A lock request is made by the Passive Entry
door handle while a door is open.
• A lock request is made by the door panel switch while the door is open.
When any of these situations occur, after all
open doors are shut, the FOBIK-Safe search
will be executed. If it finds a Passive Entry
key fob inside the car, the car will unlock and
alert the customer.
NOTE:
The vehicle will only unlock the doors when a
valid Passive Entry key fob is detected inside
the vehicle. The vehicle will not unlock the
doors when any of the following conditions
are true:
• The doors are manually locked using the door lock knobs.
• Three attempts are made to lock the doors using the door panel switch and then close
the doors.
• If the liftgate is opened and then all 4 doors are locked, the key fob will become locked
in the vehicle if the liftgate is closed and
will not alert the customer.
