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.

NOTE:
• The driver’s door key cylinder and the liftgate 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 vehicle
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.

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.
Rearming Of The System
If something triggers the alarm, and no action is taken to
disarm it, the vehicle security alarm will turn the horn off
after 29 seconds, five seconds between cycles, up to eight
cycles if the trigger remains active and the vehicle security
alarm will rearm itself.
Security System Manual Override
The vehicle security alarm will not arm if you lock the
doors using the manual door lock plunger.
Tamper Alert
If something has triggered the vehicle security alarm in
your absence, the horn will sound three times and the
exterior lights will blink three times when you disarm the
vehicle security alarm. Check the vehicle for tampering.
DOORS
Manual Door Locks
The power door locks can be manually locked from inside
the vehicle by using the door lock knob. To lock each door,
push the door lock knob on each door trim panel down-
ward. To unlock the front doors, pull the inside door
handle to the first detent. To unlock the rear doors, pull the
door lock knob on the door trim panel upward. If the lock
knob is down when the door is closed, the door will lock.
Therefore, make sure the key fob is not inside the vehicle
before closing the door.
NOTE:Manually locking the vehicle will not arm the
vehicle security alarm.

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 inside the
vehicle without first unlocking the door. The door may be
unlocked manually by raising the lock knob.
Keyless Enter-N-Go — Passive Entry
The Passive Entry system is an enhancement to the vehi-
cle’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 “Multimedia” for further infor-
mation. •
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 prevent the
passive entry system from locking/unlocking the ve-
hicle.
• 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.

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 transitions 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 follow-
ing 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 outside 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.

WARNING!
•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. They could be seriously
injured in a collision. Children should be seated and
using the proper restraint system.
Power Adjustment (Front Seats) — If Equipped
Some models may be equipped with eight-way power
driver and front passenger seats. The power seat switches
are located on the outboard side of the seat. There are two
switches that control the movement of the seat cushion and
the seatback.
Adjusting The Seat Forward Or Rearward
The seat can be adjusted both forward and rearward. Push
the seat switch forward or rearward. The seat will move in
the direction of the switch. Release the switch when the
desired position has been reached.

Pinch Protect Feature
This feature will detect an obstruction in the closing of the
sunroof during the Express Close operation. If an obstruc-
tion in the path of the sunroof is detected, the sunroof will
automatically retract. Remove the obstruction if this oc-
curs.
NOTE:If three consecutive sunroof close attempts result in
Pinch Protect reversals, Pinch Protect will disable and the
sunroof must be closed in Manual Mode.
Venting Sunroof — Express
Push and release the Vent button within one half second
and the sunroof will open to the vent position. This is
called “Express Vent” and it will occur regardless of
sunroof position. During Express Vent operation, any
movement of the switch will stop the sunroof.
Sunroof Maintenance
Use only a non-abrasive cleaner and a soft cloth to clean the
glass panel.
Relearn Procedure
For vehicles equipped with a single-pane sunroof, there is
a relearn procedure that allows you to reset the sunroof
when the “Express Open” feature stops working. To reset
the sunroof, follow these steps:
1. Set the ignition to the ACC or ON/RUN position.
2. Make sure that the sunroof is fully closed.
3. Push sunroof switch forward and hold. The sunroof will close fully then move to the Vent position after 10
seconds.
4. Release the sunroof switch, then push forward and hold the switch again within 5 seconds to begin the relearn
process. The sunroof will complete one full cycle and
return to the Fully Closed position.
NOTE: If the sunroof switch is released anytime during the
relearn cycle, the procedure will need to be repeated
starting from the first step.
5. Once the sunroof has stopped in the Fully Closed position, release the sunroof switch. The sunroof is now
reset and ready to use.
