taining security. The system has a
range of 328 ft (100 m).
The Remote Starting System also activates
the Climate Control, vented seats (if
equipped) in temperatures above 80° F
(26.7° C), and the heated seats (if
equipped), and heated steering wheel (if
equipped) in temperatures below 40° F
(4.4° C). Refer to “Heated Seats” in “Getting
To Know Your Vehicle” in the Owner’s Manual
for further information.
NOTE:

• 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 engine can be started two consecutive
times (two 15-minute cycles) with the key
fob. However, the ignition must be placed
in the ON/RUN position before you can
repeat the start sequence for a third cycle.
VEHICLE SECURITY ALARM
— IF EQUIPPED
The vehicle security alarm monitors the ve-
hicle 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 alarm provides both audible
and visible signals. If something triggers the
alarm, the vehicle security alarm 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.
To Arm The System
Follow these steps to arm the vehicle security
alarm:
1. Make sure the vehicle’s ignition is cycled
to the “OFF” position (refer to "Starting
The Engine" in "Starting And Operating"
for further information).
17

2. Perform one of the following methods to
lock the vehicle:
• Push lock on the interior power door
lock switch with the driver and/or pas-
senger door open.
• Push the lock button on the exterior
Passive Entry Door Handle with a valid
key fob available in the same exterior
zone (refer to "Keyless Enter-N-Go —
Passive Entry" in "Getting To Know Your
Vehicle" for further information).
• Push the lock button on the key fob.
3. If any doors are open, close them.
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 (if equipped, refer to "Keyless
Enter-N-Go — Passive Entry" in "Getting To
Know Your Vehicle" for further informa-
tion).• Cycle the vehicle ignition system out of the
OFF position.
NOTE:
• The driver's door key cylinder cannot arm or
disarm the vehicle security alarm.
• When the vehicle security alarm is armed,
the interior power door lock switches will
not unlock the doors.
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, and the horn will sound. If this occurs,
disarm the vehicle security alarm.

CAUTION!
Careless handling and storage of the re-
movable door panels may damage the
seals, causing water to leak into the vehi-
cle’s interior.

fere 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 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.NOTE:
If “1st Press Of Key Fob Unlock” 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
Press” and “Unlock All Doors 1st Press,”
refer to “Uconnect Settings” in “Multime-
dia” in your 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
doors and the swing gate 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 only if the ignition switch is in
the OFF position.
FOBIK-Safe only executes in vehicles with
passive entry. 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.
Grab The Door Handle To Unlock
19

• 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 finds a Passive Entry
key fob inside the car, the car will unlock and
alert the customer. If Passive Entry is dis-
abled using Uconnect System, the key pro-
tection described in "Preventing Inadvertent
Locking of Passive Entry Key Fob in Vehicle"
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 5ft
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 close
the doors.
To Lock The Vehicle’s Doors And Swing Gate
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
doors and the swing gate.NOTE:
DO NOT grab the door handle, when pushing
the door handle lock button. This could un-
lock the door(s).
The vehicle doors can also be locked by using
the lock button located on the vehicle’s inte-
rior door panel.

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.

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.
