Programming spare keys
You can program your own coded keys to your vehicle. Please read and
understand the entire procedure before you begin.
Tips:
•A maximum of eight keys can be coded to your vehicle.
•Only use Securilockkeys.
•You must have two previously programmed coded keys (keys that
already operate your vehicle’s engine) and the new unprogrammed
key(s) readily accessible.
•If no previously programmed coded keys are available, you must take
your vehicle to your dealer to have the spare key(s) programmed.
1. Insert a previously programmed
coded key into the ignition.
2. Turn the ignition from the 1
(OFF/LOCK) position to the 3 (ON)
position. Keep the ignition in the 3
(ON) position for at least one
second, but no more than 10
seconds.
3. Turn the ignition to the 1
(OFF/LOCK) position, and remove
the coded key from the ignition.
4. Within ten seconds of removing the previously programmed coded key,
insert the other previously programmed coded key into the ignition.
5. Turn the ignition from the 1 (OFF/LOCK) position to the 3 (ON)
position. Keep the ignition in the 3 (ON) position for at least one second
but not more than 10 seconds.
6. Turn the ignition to the 1 (OFF/LOCK) position, and remove the
second key from the ignition.
7. Within twenty seconds of removing the previously programmed coded
key, insert the unprogrammed key (new/valet key) into the ignition.
8. Turn the ignition from the 1 (OFF/LOCK) position to the 3 (ON)
position. Keep the ignition in the 3 (ON) position for at least one second.
9. Your new unprogrammed key is now programmed.
If the key has been successfully programmed it will start the vehicle’s
engine and the theft indicator light will illuminate for three seconds and
then go out. If the key was not successfully programmed, it will not start

your vehicle’s engine and the theft indicator light will flash on and off
rapidly. If failure repeats, bring your vehicle to your dealer to have the
new key(s) programmed.
To program additional new unprogrammed key(s), repeat this procedure
from Step 1 for each additional key.
ACTIVE ANTI-THEFT SYSTEM (IF EQUIPPED)
The active anti-theft system is designed to warn you in the event of an
unauthorized entry to your vehicle and is also designed to help prevent
the unwanted towing of the vehicle.
When the vehicle is locked and armed, the active anti-theft system
monitors the following:
•Doors
•Hood
•Trunk
•Movement inside the vehicle
•Change in vehicle inclination
Note:The active anti-theft system includes a motion detection system
which monitors the passenger cabin and a vehicle incline sensor which
detects changes in vehicle attitude.
The interior motion detection and vehicle incline sensing systems
will operate only when the vehicle is locked using the remote
keyless entry transmitter or when using the power door lock
control with the accompanying door open and all doors then
become closed. For convertible vehicles, the convertible top must
be in the fully closed and latched position for the interior motion
sensing system to arm. If you lock the vehicle using the key in the
driver door key cylinder, the system will monitor the doors,
trunk, and hood but the motion sensing and vehicle incline
sensing will not arm.
Do not arm the interior motion detection system if movement within the
vehicle is likely to occur. Additionally, do not arm the vehicle incline
sensing system when the vehicle is in transport.
For proper operation of the interior motion detection system, ensure all
windows are closed prior to arming the system. This will help prevent
accidental alarm activation due to external influences and ensure proper
interior motion detection. Additionally, the interior motion sensing
system will not arm if either door is ajar

If there is any potential active anti-theft problem with your vehicle,
ensureALL remote entry transmittersare taken to the dealership to
aid in troubleshooting.
Arming the system
When armed, the active anti-theft system is designed to notify you of an
unauthorized entry. When unauthorized entry or towing occurs, the
system will flash the turn signal lamps and interior lamps and sounds the
security horn.
The system is ready to arm whenever the key is out of the ignition. Any
of the following actions will arm the alarm system:
•Press the remote transmitter lock control one time to arm the system.
•Lock all doors using the interior power lock switch while the driver or
passenger door is open and then becomes closed.
•Lock all doors with the key in the key lock cylinder (this willnot
however arm the interior motion or vehicle incline sensing systems).
If all the closures (doors, trunk, hood) are closed, the turn signal lamps
will flash once. If the vehicle is locked again within three seconds, the
vehicle will lock again, the turn signal lamps will flash again and the horn
will chirp.
If any closure is not properly closed, the turn signal lamps will not flash
and the horn will chirp twice.
The system will wait 20 seconds after locking before triggering an alarm.
After the 20–second pre-arm phase, the power door unlock control is
disabled to further protect your vehicle.
Disarming the system
You can disarm the active anti-theft system by any of the following
actions:
•Unlock the doors by using the remote entry transmitter.
•Unlock the doors with the key in the driver door lock cylinder.
•Turn the ignition to the 3 (ON) position with a programmed coded
ignition key.
Note:Unlocking the trunk inhibits the motion sensing system, but the
system continues to monitor the doors, hood and the vehicle incline.
Once the trunk becomes closed the motion sensing system will re-arm.

SEATING
Notes:
Reclining the seatback can cause an occupant to slide under the
seat’s safety belt, resulting in severe personal injuries in the
event of a collision.
Do not pile cargo higher than the seatbacks to reduce the risk of
injury in a collision or sudden stop.
Adjustable head restraints
Your vehicle’s seats are equipped with head restraints which are
vertically adjustable. The purpose of these head restraints is to help limit
head motion in the event of a rear collision. To properly adjust your head
restraints, lift the head restraint so that it is located directly behind your
head or as close to that position as possible. Refer to the following to
raise and lower the head restraints.
Lift the head restraint to raise the
height.
To lower the head restraint, press
the button located on the driver’s
side post.
