REMOTE STARTING
SYSTEM — IF EQUIPPED
This system uses the key fob to
start the engine conveniently from
outside the vehicle while still main-
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), 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:
The vehicle must be equipped with an
automatic transmission to be equipped
with Remote Start.
Obstructions between the vehicle and key
fob may reduce this range.
How To Use Remote Start
Push the Remote Start button on the key
fob twice within five seconds. Pushing the
Remote Start button a third time shuts the
engine off.
To drive the vehicle, push the unlock
button, and place the ignition in the ON/
RUN position.
With remote start, the engine will only run
for 15 minutes (timeout) unless the igni -
tion key is placed in the ON/RUN position.
The vehicle must be started with the key
after two consecutive timeouts.
All of the following conditions must be met
before the engine will remote start:

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

VEHICLE SECURITY ALARM —
IF EQUIPPED

The vehicle security alarm 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 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 secu-
rity alarm:
1. Make sure the vehicle’s ignition is placed in the OFF position. Refer to "Starting
The Engine" in "Starting And Operating"
for further information. 2. Perform one of the following methods to
lock the vehicle:
Push lock on the interior power doorlock switch with the driver and/or
passenger 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 “Doors” in this
chapter 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 “Doors” in
this chapter for further information.
Cycle the vehicle ignition system out of
the OFF position.

17
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. Refer to "Keyless Enter-N-Go" in
“Doors” in this chapter for further infor-
mation.
Cycle the vehicle ignition system out of
the OFF position by pushing the Keyless
Enter-N-Go START/STOP ignition button
(requires at least one valid key fob in the
vehicle).
NOTE:
The driver's door key cylinder and the lift -
gate 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.
The ultrasonic intrusion sensor (motion
detector) actively monitors your vehicle
every time you arm the security system. If
you prefer, you can turn off the ultrasonic
intrusion sensor when arming the security
system. To do so, push the lock button on
the key fob three times within 15 seconds
of arming the system (while the vehicle
security light is flashing rapidly).
The vehicle security alarm is designed to
protect your vehicle; however, you can avoid
conditions where the system may give you a
nuisance alarm. Conditions include any
person, or pet, left inside the vehicle or
hanging items that may sway (e.g. from rear
view mirrors, visors, etc). Windows and roof
panels should be closed to prevent wind,
leaves, and other debris from blowing into
the vehicle. Items left in the vehicle that may
shift over a period of time (e.g. plastic bags,
clothes, or groceries), could result in a
nuisance alarm. Additionally, extreme environmental condi
-
tions (wind, rain, hail, thunder, etc.), or
extreme noise (audio systems, traffic condi -
tions, trains, etc.), or direct impacts to the
vehicle may result in a nuisance alarming
condition.
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, the horn will sound. If this occurs,
disarm the vehicle security alarm.
Security System Manual Override
The system will not arm if you lock the doors
using the manual door lock.

After engaging or disengaging the
Child-Protection Door Lock system, always
test the door from the inside to make
certain it is in the desired position.
For emergency exit with the system
engaged, move the lock lever rearward
(located on the door trim panel), roll down
the window and open the door with the
outside door handle.
NOTE:
Always use this device when carrying chil -
dren. After engaging the child lock on both
rear doors, check for effective engagement
by trying to open a door with the internal
handle. Once the Child-Protection Door Lock
system is engaged, it is impossible to open
the doors from inside the vehicle. Before
getting out of the vehicle, be sure to check
that there is no one left inside.
