Immobilizer
See Radio Frequency Statement 0348.
Immobilizer Operation
This vehicle has a passive theft-deterrent
system.
The system does not have to be manually
armed or disarmed.
The vehicle is automatically immobilized
when the vehicle is turned off.
The immobilization system is disarmed
when the ignition is on or in accessory
mode and a valid remote key is present in
the vehicle.
The security light, in the instrument cluster,
comes on if there is a problem with arming
or disarming the theft-deterrent system.
The system has one or more remote keys
matched to an immobilizer control unit in
your vehicle. Only a correctly matched
remote key will start the vehicle. If the
remote key is ever damaged, you may not
be able to start your vehicle.
When trying to start the vehicle, the
security light may come on briefly when the
ignition is turned on.
If the engine does not start and the security
light stays on, there is a problem with the
system. Turn the ignition off and try again.
If the vehicle will not change ignition modes
(accessory mode, on, off), and the remote
key appears to be undamaged, try another
remote key. Or, you may try placing the
remote key in the front cupholder located in
the center console. See Remote Key
Operation 08. If the ignition mode will not change with
the other remote key or in the front
cupholder, your vehicle needs service. If the
ignition does change modes, the first
remote key may be faulty. See your dealer
who can service the theft-deterrent system
and have a new remote key programmed to
the vehicle.
It is possible for the immobilizer system to
learn new or replacement remote keys. Up
to eight remote keys can be programmed
for the vehicle. To program additional
remote keys, see
“Programming Remote
Keys to the Vehicle” underRemote Key
Operation 08.
Do not leave the key or device that disarms
or deactivates the theft-deterrent system in
the vehicle.

Memory Seats
Overview
If equipped, the memory seat feature allows
drivers to save their unique driving positions
and a shared exit position. See“Saving
Seating Positions” later in this section. The
saved positions can be recalled manually by
all drivers, see “Manually Recalling Seating
Positions” later in this section, and drivers
with remote key 1 and 2 can also recall
them automatically. See “Auto Seat Entry
Memory Recall” or“Auto Seat Exit Memory Recall”
later in this section. To enable
automatic recalls, turn on Seat Entry

Identifying Driver Number
The vehicle identifies the current driver by
their remote key number 1–8. The current
remote key number may be identified by
Driver Information Center (DIC) welcome
message, “You are driver x for memory
recalls.” This message is displayed the first
few times the vehicle is turned on when a
different remote key is used. For Seat Entry
Memory to work properly, save positions to
the 1 or 2 memory button matching the
driver number of this welcome message. To
aid in identifying remote key IDs, it is
recommended to only carry one remote key
when entering the vehicle. Perform the
following if the welcome message is not
displayed:
1. Move all keys and remote keys away from the vehicle. 2. Start the vehicle with another remote
key. A DIC welcome message should
display indicating the driver number of
the other remote key. Turn the vehicle
off and remove the other key or remote
key from the vehicle.
3. Start the vehicle with the initial key or remote key. The DIC welcome message
should display the driver number of the
initial remote key.
Saving Seating Positions
Read these instructions completely before
saving memory positions.
To save preferred driving positions to
1 and 2: 1. Turn the vehicle on or to accessory mode. A DIC welcome message may
indicate the driver number of the current
remote key. See “Identifying Driver
Number” previously in this section.
2. Adjust all available memory features to the desired driving position.
3. Press and release SET; a beep will sound.
4. Immediately upon releasing SET, press and hold memory button 1 or 2 matching
the current remote key number until two
beeps sound. If too much time passes
between releasing SET and pressing 1
