VEHICLE SECURITY SYSTEM — IF EQUIPPED
The Vehicle Security system monitors the vehicle doors,
hood, liftgate, and the Keyless Enter ‘n Go™ Ignition for
unauthorized operation. While the Vehicle Security system
is armed, interior switches for door locks and liftgate
release are disabled. If something triggers the alarm, the
Vehicle Security system will provide the following audible
and visible signals:
The horn will pulse.
 The turn signals will flash.
 The Vehicle Security Light in the instrument cluster will
flash.
TO ARM THE SYSTEM
Follow these steps to arm the Vehicle Security system:

1. Make sure the vehicle’s ignition is placed in the OFF
position.

 For vehicles equipped with Keyless Entry, 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
Úpage 22.
 Push the lock button on the key fob.
3. If any doors are open, close them.
TO DISARM THE SYSTEM
The Vehicle Security system can be disarmed using any of
the following methods:
 Push the unlock button on the key fob.
 Grab the Passive Entry door handle to unlock the door
Úpage 22.
 Cycle the ignition out of the OFF position to disarm the
system.
NOTE:
The driver's door key cylinder and the liftgate button on
the key fob cannot arm or disarm the Vehicle Security
system.
 The Vehicle Security system remains armed during
power liftgate entry. Pushing the liftgate button will not
disarm the Vehicle Security system. If someone enters
the vehicle through the opened liftgate, then opens any
door, the alarm will sound.
 When the Vehicle Security system is armed, the interior
power door lock switches will not unlock the doors.
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. If the Vehicle Security system is armed and the battery
becomes disconnected, the Vehicle Security system 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 system.
REARMING OF THE SYSTEM
If something triggers the alarm and no action is taken to
disarm it, the Vehicle Security system will turn the horn off
after a 29 second cycle (with five seconds between cycles
and up to eight cycles if the trigger remains active) and
then rearm itself.
SECURITY SYSTEM MANUAL OVERRIDE
The Vehicle Security system will not arm if you lock the
doors using the manual door lock.

handle, the unlock sensitivity can be affected, resulting
in a slower response time.
 The doors may unlock when water is sprayed on the
Passive Entry door handles, if the key fob is located
outside of the vehicle within 5 ft (1.5 m) of the handle.
 If the vehicle is unlocked by Passive Entry and no door
is opened within 60 seconds, the vehicle will relock and
if equipped will arm the Vehicle Security system.
 The key fob may not 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 prevent the
Passive Entry handle from locking/unlocking the
vehicle.
 Passive Entry activates illuminated approach for the
time set by the customer within the Uconnect system
(0, 30, 60, or 90 seconds), and flashes the turn signal
lights. To Unlock From The Driver Or Passenger Side
With a valid Passive Entry key fob within 5 ft (1.5 m) of the
door handle, grab the handle to unlock the vehicle.
Grabbing the driver’s door handle will unlock the driver
door automatically. Grabbing the passenger door handle
will unlock all doors and the liftgate automatically.

Grab The Door Handle To Unlock

NOTE:

you grab hold of the front driver’s door handle,
depending on the selected setting in the Uconnect
system
Úpage 126.
 All doors will unlock when the front passenger door
handle is grabbed regardless of the driver’s door
unlock preference setting. Frequency Operated Button Integrated Key (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.
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
detects 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.
 If a paired key fob is found outside of the vehicle,
FOBIK-Safe will not activate.
 Three attempts are made to lock the doors using the
door panel switch and then the doors are closed.
 If the liftgate is opened and then all four doors are
locked, the key fob will become locked in the vehicle if
the liftgate is closed and will not alert the owner.
