“Administrator key” or Admin key. The Admin key can be used to create
a MyKey™, program optional MyKey™ settings, and disable the
MyKey™ feature. When the MyKey™ feature is enabled the user can use

Arming the system
When armed, this system will respond if unauthorized entry is
attempted. When unauthorized entry occurs, the system will flash the
turn signal lamps and will sound the horn.
The system is ready to arm whenever the ignition is off. Any of the
following actions will prearm the alarm system:
•Press the
control on the transmitter.
When you press the lock control twice within three seconds on your
transmitter, the horn will chirp once to let you know that all doors, the
hood and the trunk are closed. If any of these are not closed, the horn
will chirp twice to warn you that a door, the hood or the trunk is still
open.
•Press the driver or passenger
power door lock control while the
door is open, then close the door.
•Press and hold the 7•8 and 9•
0 controls on the keyless entry
pad at the same time to lock the
doors (driver’s door must be
closed).
•If equipped with Intelligent
Access Key, lock the door by
turning the key in the door key
cylinder.
There is a 20 second countdown
when any of the above actions occur
before the vehicle becomes armed.
Each door, the hood or the trunk is
armed individually, and if any are
open, they must be closed for that entry point to enter the 20 second
countdown.
The turn signal lamps will flash once when all doors, the hood or the
trunk are closed indicating the vehicle is locked and entering the
20 second countdown.

SEATING
WARNING: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.
WARNING:Do not pile cargo higher than the seatbacks to
reduce the risk of injury in a collision or sudden stop.
WARNING:Before returning the seatback to its original
position, make sure that cargo or any objects are not trapped
behind the seatback. After returning the seatback to its original
position, pull on the seatback to ensure that it has fully latched. An
unlatched seat may become dangerous in the event of a sudden stop or
collision.

crash, the driver and passenger occupants should not sit in
and/or operate the vehicle, until the head restraint is placed in its
proper position. The driver should never adjust the head restraint
while the vehicle is in motion.
The adjustable head restraints
consist of :
•a trimmed energy absorbing foam
and structure (1),
•two steel stems (2),
•a guide sleeve adjust/release
button (3),
•and a guide sleeve unlock/remove
button (4).
