To Exit Remote Start Mode Without
Driving The Vehicle
Push and release the remote start button one
time or allow the engine to run for the entire
15-minute cycle.
NOTE:
To avoid unintentional shut downs, the sys-
tem will disable the one time push of the
remote start button for two seconds after
receiving a valid remote start request.
To Exit Remote Start Mode And Drive The
Vehicle
Before the end of the 15-minute cycle, push
and release the unlock button on the key fob
to unlock the doors and disarm the vehicle
security alarm (if equipped). Then, insert the
key into the ignition and place the ignition in
the ON/RUN position.
NOTE:
The ignition must be placed in the ON/RUN
position in order to drive the vehicle.
SENTRY KEY
The Sentry Key Immobilizer System prevents
unauthorized vehicle operation by disabling
the engine. The system does not need to be
armed or activated. Operation is automatic,
regardless of whether the vehicle is locked or
unlocked.
The system uses key fobs that have an em-
bedded electronic chip (transponder) to pre-
vent unauthorized vehicle operation. There-
fore, only key fobs that are programmed to
the vehicle can be used to start and operate
the vehicle. The system will shut the engine
off in two seconds if someone uses an invalid
key to try to start the engine.
NOTE:
A key fob that has not been programmed is
also considered an invalid key, even if it is cut
to fit the ignition or lock cylinder for that
vehicle.
During normal operation, after placing the
ignition in the on position, the vehicle secu-
rity light will turn on for three seconds for abulb check. If the light remains on after the
bulb check, it indicates that there is a prob-
lem with the electronics. In addition, if the
vehicle security light begins to flash after the
bulb check, it indicates that someone used
an invalid key to try to start the engine. Either
of these conditions will result in the engine
being shut off after two seconds.
If the vehicle security light turns on during
normal vehicle operation (vehicle running for
longer than ten seconds), it indicates that
there is a fault in the electronics. Should this
occur, have the vehicle serviced as soon as
possible by an authorized dealer.
CAUTION!
The Sentry Key Immobilizer system is not
compatible with some aftermarket remote
starting systems. Use of these systems
may result in vehicle starting problems
and loss of security protection.
All of the key fobs provided with your new
vehicle have been programmed to the vehicle
electronics.GETTING TO KNOW YOUR VEHICLE

Replacement Key Fobs
NOTE:
Only key fobs that are programmed to the
vehicle electronics can be used to start and
operate the vehicle. Once a key fob is pro-
grammed to a vehicle, it cannot be pro-
grammed to any other vehicle.
CAUTION!
Always remove the Sentry Keys from the
vehicle and lock all doors when leaving the
vehicle unattended.
Duplication of key fobs may be performed at
an authorized dealer or by following the cus-
tomer key programming procedure. This pro-
cedure consists of programming a blank key
fob to the vehicle electronics. A blank key fob
is one that has never been programmed.
NOTE:
When having the Sentry Key Immobilizer Sys-
tem serviced, bring all vehicle key fobs with
you to an authorized dealer.
Customer Key Programming
If you have two valid key fobs, you can pro-
gram new key fobs to the Sentry Key Immo-
bilizer system by performing the following
procedure:
1. Cut the additional key(s) to match the
ignition and lock cylinder key code.
2. Insert the first valid key into the ignition.
Place the ignition in the ON/RUN position
for at least three seconds, but no longer
than 15 seconds. Then, place the ignition
in the LOCK position and remove the first
key.
3. Insert the second valid key into the igni-
tion. Place the ignition in the ON/RUN
position within 15 seconds. After 10 sec-
onds, a chime will sound. In addition, the
Vehicle Security Light will begin to flash.
Place the ignition in the LOCK position
and remove the second key.
4. Insert a blank key into the ignition. Place
the ignition in the ON/RUN position
within 60 seconds. After 10 seconds, asingle chime will sound. In addition, the
Vehicle Security Light will stop flashing.
To indicate that programming is com-
plete, the Vehicle Security Light will turn
on again for three seconds and then turn
off.
The new key is programmed. The key fob
will also be programmed during this pro-
cedure.
Repeat this procedure to program up to eight
keys. If you do not have a programmed key
fob, contact your authorized dealer for de-
tails.
NOTE:
If a programmed key fob is lost, see your
authorized dealer to have all remaining key
fobs erased from the system's memory. This
will prevent the lost key from starting your
vehicle. The remaining key fobs must then be
reprogrammed. All vehicle key fobs must be
taken to an authorized dealer at the time of
service to be reprogrammed.

VEHICLE SECURITY ALARM
— IF EQUIPPED
The vehicle security alarm monitors the ve-
hicle doors, swing gate, and ignition for un-
authorized operation. While the vehicle secu-
rity alarm is armed, interior switches for door
locks are disabled. The vehicle security alarm
provides both audible and visible signals
when alarming. The horn will sound, the
headlights will turn on, the park lamps and/or
turn signals will flash repeatedly for three
minutes. If the disturbance is still present
(driver's door, passenger door, other doors,
ignition) after three minutes, the headlights,
park lamps and/or turn signals will flash for
an additional 15 minutes.
Rearming The System
If something triggers the alarm, and no action
is taken to disarm it, the vehicle security
alarm will turn off the horn after three min-
utes, turn off all of the visual signals after
15 minutes, and then the vehicle security
alarm will rearm itself.
To Arm The System
The vehicle security alarm will set when you
use the Remote Keyless Entry key fob to lock
the doors and swing gate, or when you use the
power door lock switch while the door is
open. After all the doors are locked and
closed, the vehicle security light (located on
the instrument cluster) will flash rapidly for
about 16 seconds to signal that the vehicle
security alarm is arming. During this 16-
second arming period, opening any door or
the swing gate will cancel the arming. If the
vehicle security alarm is successfully set, the
vehicle security light will flash at a slower
rate to indicate the vehicle security alarm is
armed.
To Disarm The System
To disarm the vehicle security alarm, you will
need to push the unlock button on the key
fob, or turn the ignition switch to the ON/
RUN position. If something has triggered the
vehicle security alarm in your absence, the
horn will sound three times, and the exterior
lights blink three times when you unlock the
doors. Check the vehicle for tampering.The vehicle security alarm is designed to
protect your vehicle; however, you can create
conditions where the vehicle security alarm
will arm unexpectedly. If you remain in the
vehicle and lock the doors with the key fob,
once the vehicle security alarm is armed
(after 16 seconds), when you pull the door
handle to exit, the alarm will sound. If this
occurs, push the unlock button on the key fob
to disarm the vehicle security alarm. You may
also accidentally disarm the vehicle security
alarm by unlocking the driver's door with the
key and then locking it. The door will be
locked but the vehicle security alarm will not
arm.
NOTE:
• Unlocking the doors with the manual door
lock plungers or the driver's door lock cyl-
inder will not disarm the vehicle security
alarm.
• When the vehicle security alarm is armed,
the interior power door lock switches will
not unlock the doors.

Seats are a part of the Occupant Restraint
System of the vehicle.
WARNING!
• It is dangerous to ride in a cargo area,
inside or outside of a vehicle. In a colli-
sion, people riding in these areas are
more likely to be seriously injured or
killed.
• Do not allow people to ride in any area of
your vehicle that is not equipped with
seats and seat belts. In a collision,
people riding in these areas are more
likely to be seriously injured or killed.
• Be sure everyone in your vehicle is in a
seat and using a seat belt properly.
Heated Seats — If Equipped
On some models, the front driver and passen-
ger seats may be equipped with heaters in
both the seat cushions and seatbacks.

There are two heated seat switches that allow
the driver and passenger to operate the seats
independently. The controls for each seat are
located on a switch bank near the bottom
center of the instrument panel.
You can choose from HI, LO or OFF heat
settings. Amber indicator lights in each
switch indicate the level of heat in use. Two
indicator lights will illuminate for HI, one for
LO and none for OFF.Push the switch once to select HI-level heat-
ing. Push the switch a second time to select
LO-level heating. Push the switch a third
time to shut the heating elements OFF.
When the HI-level setting is selected, the
heater will provide a boosted heat level dur-
ing the initial stages of operation. Then, the
heat output will drop to the normal HI-level.
If the HI-level setting is selected, the system
will automatically switch to LO-level after
approximately 30 minutes of continuous op-
eration. At that time, the number of illumi-
nated LEDs changes from two to one, indicat-
ing the change. The LO-level setting will turn
OFF automatically after approximately
30 minutes.
NOTE:
When a heat setting is selected, heat will be
felt within two to five minutes.

tion or other physical condition must
exercise care when using the seat
heater. It may cause burns even at low
temperatures, especially if used for long
periods of time.
• Do not place anything on the seat or
seatback that insulates against heat,
such as a blanket or cushion. This may
cause the seat heater to overheat. Sit-
ting in a seat that has been overheated
could cause serious burns due to the
increased surface temperature of the
seat.
