Servicing Your Air Bag-Equipped
Vehicle
Air bags affect how your vehicle should be serviced.
There are parts of the air bag systems in several places
around your vehicle. Your dealer and the service manual
have information about servicing your vehicle and the air
bag systems. To purchase a service manual, see
Service
Publications Ordering Information on page 7-11.
{CAUTION:
For up to 10 seconds after the ignition key is
turned off and the battery is disconnected, an
air bag can still in¯ate during improper
service. You can be injured if you are close to
an air bag when it in¯ates. Avoid 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 quali®ed to do so.
The air bag systems do not need regular maintenance.

Your vehicle can be programmed to one of the following
modes.
Mode 1:No Veri®cation
Mode 2:Horn Chirp only
Mode 3:Headlamps Flash only

either exit the programming mode by following
the instructions listed here or program the
next feature available on your vehicle.
4. Each additional press of the remote keyless entry

advance the lock mode by one, starting from
the current lock mode.

Mode 1. When the door lock switch is released,
the vehicle will remain in the most recent lock mode.
The mode you selected is now set. You can either exit
the programming mode by following the previous
instructions or program the next feature available on
your vehicle.
Disconnecting the vehicle's battery for up to a year will
not change the programmed mode for the lock and
unlock security feedback features.

Delayed Locking
Delayed locking allows the doors to be locked while the
passengers are exiting the vehicle. This feature also
allows a brief time period for you to re-enter the vehicle
after the doors have been closed. Delayed locking is
user programmable for enabling or disabling the feature.
Delayed locking is activated when a door lock switch
is pressed while the key is not in the vehicle's ignition,
and a door is open. The door lock switch may be
either the lock switch on the door or on the remote
keyless entry transmitter. See ªRemote Keyless Entry
System Operationº earlier in this section for more
details. The doors do not lock when the lock switch is
pressed, but instead, three chimes are heard. These
chimes indicate that the delayed locking function
has been activated.
You have three actions possible once delayed locking is
activated:
·Cancel the delayed locking by pressing the unlock
switch or by fully inserting the key in the ignition.
·Override the delayed locking feature and lock the
doors immediately by pressing the lock switch a
second time.
·Let the delayed locking feature complete the locking
of the vehicle.If you wish to let the delayed locking feature complete
the locking of the vehicle, no additional action is
required. The delayed locking feature will lock the doors
automatically after all the doors have been closed for
a period of ®ve seconds. During this ®ve second period,
any door may be reopened, at which time the three
possible actions shown above are again available.
You may also customize your vehicle to activate the
delayed locking feature as described previously, or you
may choose to completely disable the feature at all
times. If disabled, the power door locks will activate
immediately when a power door lock switch is pressed.
The enabled/disabled state of the delayed locking
feature will be toggled when you perform the following
sequence:
1. Close the doors.
2. Move the ignition key to the RUN position.
3. Apply your regular brakes.
4. Press and hold the power door unlock switch. While
holding the door unlock switch, move the shift lever
out of and back into PARK (P).
2-7

After an initial transaxle cycle, each additional cycle will
toggle the enable/disable state of the delayed locking
feature. During this procedure, the chime will sound,
providing you with feedback. In Mode 1, a single chime
will be heard if the delayed locking feature is disabled.
In Mode 2, two chimes will be heard if the feature
is enabled. When the door lock switch is released, the
vehicle will remain in the most recent operating mode.
Disconnecting the vehicle battery for up to a year will not
change the programmed mode for the delayed locking
feature.
Illumination on Remote Activation
This feature provides interior lighting when a remote
keyless entry door unlock command is received by your
vehicle. Your ignition must be off for this feature to
work. The interior lamps will light until either the ignition
is turned to RUN or until a period of 40 seconds has
elapsed. If a door is opened during this period, the timed
lighting will be canceled, and the interior lamps will
remain on. Also see ªEntry Lightingº under
Interior
Lamps on page 3-14for more information.
Matching Transmitter(s) to Your
Vehicle
Each remote keyless entry transmitter is coded to
prevent another transmitter from unlocking your vehicle.
If a transmitter is lost or stolen, a replacement can
be purchased through your dealer. Remember to bring
any remaining transmitters with you when you go to
your dealer. When the dealer matches the replacement
transmitter to your vehicle, any remaining transmitters
must also be matched. Once your dealer has coded the
new transmitter, the lost transmitter will not unlock
your vehicle. Each vehicle can have a maximum of four
transmitters matched to it.
Battery Replacement
Under normal use, the battery in your remote keyless
entry transmitter should last about three years.
You can tell the battery is weak if the transmitter won't
work at the normal range in any location. If you have
to get close to your vehicle before the transmitter works,
it's probably time to change the battery.
