transmission or the parking brake is engaged for a
manual transmission, push and release the numbered
memory button you just stored. The seat will move to
the set position. You will hear one chime.
Pressing the UNLOCK button of a keyless entry
transmitter will adjust the seat to the corresponding
stored memory position. You will hear one chime.
Repeat Steps 1 and 2 to readjust the seat. The transmitter
need not be reprogrammed unless it needs to correspond
to the other numbered memory button.

steps, but use the other numbered button and the other
keyless entry transmitter.

adjust the seat. Pressing any of the seat adjuster switches,
the SET button or pressing the desired memory button
twice will cause the seat to stop moving.

and start the vehicle while the seat is still adjusting,
adjustment will pause while the ignition is in START.

low. Press the upper part of the switch to turn the heater

Air bags are designed to inflate only once. After they
inflate, you'll need some new parts for your air bag
system. If you don't get them, the air bag system
won't be there to help protect you in another crash.
A new system will include air bag modules and
possibly other parts. The service manual for your
vehicle covers the need to replace other parts.

Your vehicle is equipped with a diagnostic module,
which records information about the air bag system.
The module records information about the readiness
of the system, when the system commands air bag
inflation and driver's safety belt usage at deployment.

Let only qualified technicians work on your air bag
system. Improper service can mean that your air bag
system won't work properly. See your dealer for service.
NOTICE:
If you damage the covering for the driver's or the
right front passenger's air bag, the bag may not
work properly. You may have to replace the air
bag module in the steering wheel or both the air
bag module and the instrument panel for the
right front passenger's air bag. Do not open or
break the air bag coverings.
Servicing Your Air Bag-Equipped Vehicle
Air bags affect how your vehicle should be serviced.
There are parts of the air bag system in several places
around your vehicle. You don't want the system to
inflate while someone is working on your vehicle.
Your dealer and the service manual have information
about servicing your vehicle and the air bag system.
To purchase a service manual, see ªService and Owner
Publicationsº in the Index.
CAUTION:
For up to 10 minutes after the ignition key is
turned off and the battery is disconnected, an air
bag can still inflate during improper service. You
can be injured if you are close to an air bag when
it inflates. Avoid wires wrapped with yellow tape
or yellow connectors. They are probably part
of the air bag system. Be sure to follow proper
service procedures, and make sure the person
performing work for you is qualified to do so.
The air bag system does not need regular maintenance.

This vehicle has one
double
-sided key for the
ignition, endgate/liftgate,
spare tire lock (two
-door
vehicles) and door locks.
It will fit with either
side up.
When a new vehicle is delivered, the dealer provides the
owner with a pair of identical keys and a key code number.
The key code number tells your dealer or a qualified
locksmith how to make extra keys. Keep this number in
a safe place. If you lose your keys, you'll be able to have
new ones made easily using this number. Your selling
dealer should also have this number.
NOTICE:
Your vehicle has a number of new features that
can help prevent theft. But you can have a lot of
trouble getting into your vehicle if you ever lock
your key inside. You may even have to damage
your vehicle to get in. So be sure you have an
extra key.
If you ever do get locked out of your vehicle, contact
roadside assistance for help. See ªRoadside Assistanceº
in the Index for more information.

Your vehicle left the factory programmed to have no
doors lock and none of the doors unlock. You can set the
automatic lock feature to lock all the doors when the
vehicle speed is greater than 15 mph (24 km/h) for
two seconds, and then unlock all the doors once the key
is removed from the ignition. The following instructions
detail how to program your door locks differently than
the factory setting. Choose one of the four programming
options listed above before entering the program mode.
To enter the program mode you need to do the following:
1. Begin with the ignition in OFF. Then pull the turn
signal/multifunction lever toward you and hold it
there while you perform the next step.
2. Turn the key to RUN and OFF twice. Then, with the
key in OFF, release the turn signal/multifunction
lever. Once you do this, you will hear the lock switch
lock and unlock and a 30 second program timer
will begin.3. You are now ready to program the automatic
door locks. Select one of the four programming
options listed above, and follow the instructions.
You will have 30 seconds to begin programming.
If you exceed the 30 second limit, the locks will
automatically lock and unlock to indicate that you
have left the program mode. If this occurs, repeat the
procedure beginning with Step 1.
You can exit the program mode any time by turning the
ignition to RUN (the locks will automatically lock and
unlock to indicate that you are leaving the program mode).
If the lock/unlock switches are not pressed while in the
programming mode, the current auto lock/unlock setting
will not be modified.
See your dealer for more information.
