NTRY (IF EQUIPPED)
The Passive Entry system is a feature that allows you to
lock and unlock the vehicle’s door(s) and swing gate
without having to push the key fob lock or unlock buttons.
NOTE:
 Passive Entry may be programmed on/off within the
Uconnect Settings Úpage 184.
 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
interfere with the key fob’s wireless signal and prevent
the Passive Entry system from locking/unlocking the
vehicle.
 Passive Entry Unlock initiates illuminated approach
(low beams, license plate lamp, position lamps) for
whichever duration is set between 0, 30, 60 or
90 seconds. Passive Entry Unlock also initiates two
flashes of the turn signals.
WARNING!
For personal security reasons and safety in a colli -
sion, lock the vehicle doors when you drive, as well as
when you park and exit the vehicle.
 When exiting the vehicle, always switch off the igni -
tion and remove the key from the vehicle. Unsuper -
vised use of vehicle equipment may cause severe
personal injuries and death.
 Never leave children alone in a vehicle, or with
access to an unlocked vehicle.
 Allowing children to be in a vehicle unattended is
dangerous 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. A child could operate

If wearing gloves, or if it has been raining/snowing, or
there is salt/dirt covering 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 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 swing gate automatically.

Grab The Door Handle To Unlock

NOTE: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
Úpage 184. 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 only if the ignition switch is in the OFF
position.
FOBIK-Safe only executes in vehicles with a START/STOP
ignition. 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 vehicle, the
vehicle will unlock and alert the customer. If Passive Entry
is disabled using Uconnect system, the key fob protection
described in this section remains active/functional.
NOTE:The vehicle will only unlock the doors during a FOBIK-Safe
operation 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:
 A second valid Passive Entry key fob is detected
outside of the vehicle (within 5 ft (1.5 m) of a Passive
Entry door handle). 
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.
To Lock The Vehicle’s Doors And Swing Gate
With one of the vehicle’s Passive Entry key fobs within 5 ft
(1.5 m) of the driver or passenger front door handles,
pushing the Passive Entry lock button will lock the vehicle
doors and the swing gate.

OUR DOOR MODELS
To provide additional storage area, each rear seat can be
folded flat to allow for extended cargo space.
NOTE:
 Be sure that the front seats are fully upright and posi -
tioned forward. This will allow the rear seat to fold down
easily.
 The center head restraints must be in the lowest posi-
tion to avoid contact with the center console when
folding the seat.
To Fold Down The Rear Seat

NOTE:You may experience deformation in the seat cushion from
the seat belt buckles if the seats are left folded for an
extended period of time. This is normal. By simply
unfolding the seats to the open position, the seat cushion
will return to its normal shape over time.
To Raise The Rear Seat
Raise the seatback and lock it into place. Then, raise the
head restraint until it locks into place. If interference from
the cargo area prevents the seatback from fully locking,
you will have difficulty returning the seat to its proper
position.
