• Once the security system is armed, it re-
mains in that state until you disarm it by
following either of the disarming proce-
dures described. If a power loss occurs
after arming the system, you must disarm
the system after restoring power to prevent
alarm activation.
• The ultrasonic intrusion sensor (motion de-
tector) actively monitors your vehicle every
time you arm the security system. If you
prefer, you can turn off the ultrasonic intru-
sion sensor when arming the security sys-
tem. To do so, push the lock button on the
key fob three times within 15 seconds of
arming the system (while the vehicle secu-
rity light is flashing rapidly).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 Unlock Door
Handle (refer to "Keyless Enter-N-Go" in
“Doors” in Getting To Know Your Vehicle" in
your Owner’s Manual for further informa-
tion).
• Cycle the vehicle ignition system out of the
OFF position.
– For vehicles equipped with Keyless
Enter-N-Go, push the Keyless Enter-
N-Go Start/Stop button (requires at
least one valid key fob in the vehicle).
– For vehicles not equipped with Keyless
Enter-N-Go, insert a valid key into the
ignition switch and turn the key to the
ON position.
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 armed
during 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 ultrasonic intrusion sensor (motion de-
tector) actively monitors your vehicle every
time you arm the security system. If you
prefer, you can turn off the ultrasonic intru-
sion sensor when arming the security sys-
tem. To do so, push the lock button on the
key fob three times within 15 seconds of
arming the system (while the vehicle secu-
rity light is flashing rapidly).
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, the horn will sound. If this occurs,
disarm the vehicle security alarm.
Security System Manual Override
The system will not arm if you lock the doors
using the manual door lock plunger.
DOORS
Keyless Enter-N-Go — Passive Entry
The Passive Entry system is an enhancement
to the vehicle’s key fob and a feature of
Keyless Enter-N-Go — Passive 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.
• 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 system from locking/
unlocking the vehicle.
• Passive Entry Unlock initiates illuminated
approach (Low Beams, License Plate
Lamp, Position Lamps) for whichever time
duration is set between 0, 30 (default),
60 or 90 seconds. Passive Entry Unlock
also initiates two flashes of the turn signal
lamps.
• 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.
To Unlock From The Driver Side
With a valid Passive Entry key fob within 5 ft
(1.5 m) of the driver's door handle, grab the
front driver door handle to unlock the driver's
door automatically.
Grab The Door Handle To Unlock
21

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 5 ft
(1.5 m) 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 (“Un-
lock Driver Door 1st Press” 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 switch is in the
OFF position.
FOBIK-Safe only executes in vehicles with
passive entry. There are five 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 the vehicle security alarm is in pre-
arm or armed status and the liftgate transi-
tions from open to closed.
• When the liftgate transitions from opened
to closed and remote start is active.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.
• There is a valid Passive Entry key fob out-
side the vehicle within 5 ft. (1.5 m) of a
Passive Entry door handle.
To Lock The Vehicle’s Doors And Liftgate
With one of the vehicle’s Passive Entry key
fob within 5 ft (1.5 m) of the driver or
passenger front door handles, pushing the
passive entry lock button will lock the
vehicle.
