REMOTE START — IF EQUIPPED (DIESEL)
This system uses the key fob to start the engine
conveniently from outside the vehicle while still
maintaining security. The system has a range
of approximately 300 ft (91 m).
Remote Start is used to defrost windows in cold weather,
and to reach a comfortable climate in all ambient
conditions before the driver enters the vehicle.
NOTE:
 The vehicle must be equipped with an automatic trans -
mission to be equipped with Remote Start.
 Obstructions between the vehicle and the key fob may
reduce this range.
 The Remote Start system will wait for the Wait To Start
Indicator Light
Úpage 116 to extinguish before
cranking the engine. This allows time for the engine
preheat cycle to heat the cylinder air, and is normal in
cold weather.
HOW TO USE REMOTE START
Push and release the Remote Start button on the key fob
twice within five seconds. The vehicle doors and swing
gate will lock, the turn signals will flash twice, and the horn
will chirp twice. Pushing the Remote Start button again will
shut the engine off.
NOTE:
 With Remote Start, the engine will only run for
15 minutes.
 Remote Start can only be used twice.
 If an engine fault is present or fuel level is low, the
vehicle will start and then shut down in 10 seconds.
 The park lamps will turn on and remain on during
Remote Start mode.
 For security, power window operation is disabled when
the vehicle is in the Remote Start mode.
 The ignition must be placed in the ON/RUN position
before the Remote Start sequence can be repeated for
a third cycle.

VEHICLE SECURITY SYSTEM — IF EQUIPPED
The Vehicle Security system monitors the vehicle doors for
unauthorized entry and the ignition switch for
unauthorized operation. When the alarm is activated, the
interior switches for door locks are disabled. The Vehicle
Security system provides both audible and visible signals.
If something triggers the alarm, the Vehicle Security
system will provide the following audible and visible
signals: the horn will pulse, the park lamps and/or turn
signals will flash, and the Vehicle Security Light in the
instrument cluster will flash.WARNING!
 Do not start or run an engine in a closed garage or
confined area. Exhaust gas contains carbon
monoxide (CO) which is odorless and colorless.
Carbon monoxide is poisonous and can cause
serious injury or death when inhaled.
 Keep key fobs away from children. Operation of the
Remote Start system, windows, door locks or other
controls could cause serious injury or death.

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.

60/40 SPLIT FOLDING REAR SEAT —
F
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
There are two release levers located on each upper
outboard side of the rear seat. The larger of the two
release levers folds down the seat and the head restraint
simultaneously. The smaller lever folds down the head
restraint independently for improved visibility.
To fold the seat, lift upward on the large release lever and
slowly fold down the seatback. The head restraint will fold
automatically with the seat when this lever is pulled.

Seatback Release Lever

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.
