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 Ú page 20.
Cycle the ignition out of the OFF position to
disarm the system.
NOTE:
The driver's door key cylinder and the trunk
button on the key fob cannot arm or disarm the
Vehicle Security system. Use of the door key
cylinder when the system is armed will sound
the alarm when the door is opened.
If Passive Entry (if equipped) is used to unlock
the trunk, the Vehicle Security system is
disarmed and the rest of the vehicle doors will
remain locked unless all doors are set to unlock
on first press within Uconnect Settings.
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
y ou

r 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
b

ttery 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.
TAMPER ALERT
If something has triggered the Vehicle Security
system in your absence, the horn will sound three

POWER DOOR LOCKS
The power door lock switches are located on each
front door panel. Push the switch to lock or unlock
the doors.

Power Door Lock Switches

The driver’s door will unlock automatically if the
ke
ys are detected inside the vehicle when the door

the door. This will occur for two attempts. Upon the
third attempt, the doors will lock even if the key is
inside.
NOTE:
If the key fob is located next to a mobile phone,
l a
ptop, or other electronic device, the wireless
signal may get blocked, and the driver’s door may
not unlock automatically. If the door lock switch is pushed while the ignition
is

in ACC or ON/RUN and the driver's door is open,
the doors will not lock.
If a rear door is locked, it cannot be opened from
i n

side the vehicle without first unlocking the door.
The door may be unlocked manually by raising the
lock knob.
KEYLESS ENTER ‘N GO™ —
P
ASSIVE ENTRY
The Passive Entry system is an enhancement to
the vehicle’s key fob and a feature of Keyless Enter
‘n Go™. This feature allows you to lock and unlock
the vehicle’s door(s) without having to push the key
fob lock or unlock buttons.
NOTE:
Passive Entry may be programmed on/off
through Uconnect Settings Ú page 122.
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 elec
-
tronic device; these devices may block the key
f ob

’s wireless signal and prevent the Passive
Entry handle from locking/unlocking the
vehicle.
Passive Entry Unlock initiates illuminated
approach (low beams, license plate lamp, posi -
tion lamps) for whichever time duration is set
WARNING!
For personal security and safety in the event
of a collision, lock the vehicle doors before you
drive as well as when you park and leave the
vehicle.
When exiting the vehicle, always make sure
the Keyless Enter ‘n Go™ — Ignition is placed
in the OFF position, 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 chil -
dren to be in a vehicle unattended is
d a

ngerous 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 children, and do
not leave the ignition of a vehicle equipped
with Keyless Enter ‘n Go™ — Ignition in the
ACC or ON/RUN position. A child could operate
power windows, other controls, or move the
vehicle.

Unlock also initiates two flashes of the turn
signal lamps.
If wearing gloves, 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 relock and (if equipped) will arm the
Vehicle Security system.
To Unlock From The Driver Or Passenger Side
With a Passive Entry key fob within 5 ft (1.5 m) of
t h

e door handle, grab the handle to unlock the
vehicle. Grabbing the driver’s door handle will

Either the driver door only or all doors will unlock
when you grab hold of the front driver’s door
handle, depending on the selected setting in the
Uconnect system
Ú page 122.
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
( F

OBIK-Safe)
To minimize the possibility of unintentionally
loc
king 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 in the OFF position.
There are three situations that trigger a
F O

BIK-Safe search in any Passive Entry vehicle.

1. A lock request is made by a valid Passive E
ntry key fob while a door is open.

2. A lock request is made by the Passive Entry d
oor handle while a door is open.
3. A lock request is made by the door panel s
witch while the door is open.
When any of these situations occur, after all open
door
s are shut, the FOBIK-Safe search will be
executed. If it detects a Passive Entry key fob
inside the vehicle, the vehicle will unlock and alert
the customer.
NOTE:
The vehicle will only unlock the doors when a valid
P a
ssive 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 the doors
are closed.
There is a valid Passive Entry key fob outside the
vehicle and within 5 ft (1.5 m) of either Passive
E n
try door handle.
To Lock The Vehicle’s Doors And Trunk
With one of the vehicle’s Passive Entry key fobs
w i

thin 5 ft (1.5 m) of either door handle, pushing

Be certain that the seatback is securely
locked into position. If the seatback is not
securely locked into position, the seat will not
provide the proper stability for child seats
and/or passengers. An improperly latched
seat could cause serious injury.
The cargo area in the rear of the vehicle (with
the rear seatbacks in the locked-up or folded
down position) should not be used as a play
area by children when the vehicle is in motion.

HEAD RESTRAINTS
Head restraints are designed to reduce the risk of
injury by restricting head movement in the event of
a rear impact. Head restraints should be adjusted
so that the top of the head restraint is located
above the top of your ear.
NOTE:
Do not reverse the head restraints (making the
r e
ar of the head restraint face forward) in an
attempt to gain additional clearance to the back of
your head.
Reactive Head Restraints — Front Seats
The front driver and passenger seats are equipped
with Reactive Head Restraints (RHR). In the event
of a rear impact, the RHR will automatically extend
forward minimizing the gap between the back of
the occupant’s head and the RHR.
The RHR will automatically return to their normal
p os

ition following a rear impact. If the RHR do not
return to their normal position, see an authorized
dealer immediately.
To raise the head restraint, pull upward on the
he

injury in the event of a crash.
Head restraints should never be adjusted
while the vehicle is in motion. Driving a vehicle
with the head restraints improperly adjusted
or removed could cause serious injury or
death in the event of a collision.
