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
in¯ate 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
Service Publications
Ordering Information on page 7-11.
{CAUTION:
For up to 10 seconds after the vehicle 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 wires,
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 quali®ed to do so.
The air bag systems do not need regular maintenance.
Restraint System Check
Checking Your Restraint Systems
Now and then, make sure the safety belt reminder light
and all your belts, buckles, latch plates, retractors
and anchorages are working properly. Look for any other
loose or damaged safety belt system parts. If you see
anything that might keep a safety belt system from doing
its job, have it repaired.
Torn or frayed safety belts may not protect you in a
crash. They can rip apart under impact forces. If a belt
is torn or frayed, get a new one right away.
Also look for any opened or broken air bag covers, and
have them repaired or replaced. (The air bag system
does not need regular maintenance.)

Changes or modi®cations to this system by other than
an authorized service facility could void authorization to
use this equipment.
If you ever notice a decrease in the remote keyless
entry transmitter range, try doing one of the following:
·Check the distance. You may be too far from
your vehicle. You may need to stand closer during
rainy or snowy weather.
·Check the location. Other vehicles or objects may
be blocking the signal. Take a few steps to the
left or right, hold the transmitter higher, and
try again.
·Check to determine if battery replacement is
necessary. See ªBattery Replacementº under
Keyless Access System Operation on page 2-4.
·Check to make sure that an electronic device such
as a cellular phone or lap top computer is not
causing interference.
·If you're still having trouble, see your dealer or a
quali®ed technician for service.
Keyless Access System Operation
Your vehicle has a keyless access system that
allows you to lock and unlock your doors, unlock
your trunk lid and disarm or arm your theft-deterrent
system. The range distance is as much as 100 feet
(30 m) away.
Your vehicle comes
standard with two
transmitters, and up to four
can be matched to your
vehicle. See ªMatching
Transmitter(s) to Your
Vehicleº later in this
section.
Q(Lock):Press this button to lock the doors. The
light on the door will ¯ash once. If this button is pressed
twice, the doors will lock, the light will ¯ash once and
the horn will sound once.

Battery Replacement
Under normal use, the battery in your keyless access
transmitter should last about three years.
You can tell the battery is weak if the transmitter will not
work at the normal range in any location. If you have
to get close to your vehicle before the transmitter works,
it is probably time to change the battery.
A weak battery may also cause the DIC to display NO
FOBS DETECTED when you try to start the vehicle. If
this happens, place the transmitter in the glove box
transmitter pocket with the buttons facing to the right.
Then, with the vehicle in PARK (P) or NEUTRAL (N),
press the brake pedal and the START button. Although
this will start the vehicle, it is recommended that you
replace the transmitter battery as soon as possible. The
DIC may display FOB BATTERY LOW.
Notice:When replacing the battery, use care not to
touch any of the circuitry. Static from your body
transferred to these surfaces may damage the
transmitter.1. Insert a coin or similar object into the slot on the
back of the transmitter and gently pry apart the
front and back.
2. Gently pull the battery out of the transmitter.
3. Put the new battery in the transmitter, positive (+)
side up. Use a battery, type CR2032, or equivalent.
4. Reassemble the transmitter. Make sure to put
it together so water will not get in.
5. Test the transmitter.

After a power reconnect such as battery replacement,
the express-up feature will not function until the
system is reinitialized. To reinitialize the express-up
once power is restored, do the following:
1. Close the door.
2. Raise the window by holding the up arrow on the
power window switch.
3. Hold the up arrow for three seconds after the
window is closed. Release the switch. Then hold the
up arrow again for three seconds.
If the express-up system has not been reinitialized, the
windows cannot be raised with the door open.
Express-Down Window
This feature is on both power windows. Press the down
arrow on the switch to the second position to activate
the express-down feature. If you want to stop the
window as it is lowering, press the switch again.
Express-Up Window
This feature is on both power windows. Press the up
arrow on the switch to the second position to activate the
express-up feature. If you want to stop the window as
it is raising, press the switch again.

amount when the door is opened. Then, when the door
is closed, the window will raise to its full up position.

Theft-Deterrent Systems
Vehicle theft is big business, especially in some cities.
Although your vehicle has a number of theft-deterrent
features, we know that nothing we put on it can make it
impossible to steal. However, there are ways you
can help.
Theft-Deterrent System
Your vehicle is equipped with a theft-deterrent alarm
system.
With this system, the
security light will ¯ash
when the door is open and
locked with the power
door lock switch.
If this light is on continuously while the engine is
running, your vehicle needs service.
Arming the System
Use one of the two following items listed here to arm
the system:
·Press the lock button on the keyless access
transmitter.
·Open the door. Lock the door with the power door
lock switch. The SECURITY light should ¯ash.
Close the door. The SECURITY light will stop
¯ashing and stay on. After 30 seconds, the light
should turn off.
·The vehicle can be programmed to automatically
lock the doors when you exit the vehicle. See
DIC Vehicle Personalization on page 3-66.
Now, if a door or the trunk lid is opened without the
keyless access transmitter, the alarm will go off. Your
horn will sound for two minutes, then it will go off to save
battery power. And, your vehicle will not start without
a keyless transmitter present.
The theft-deterrent system will not arm if you lock the
driver's door with the power door lock switch after
the doors are closed.
If your passenger stays in the vehicle when you leave
with the keyless access transmitter, have the passenger
lock the vehicle after the doors are closed. This way the
alarm will not arm, and your passenger will not set it off.
2-17

When the engine is off, press this button to place the
vehicle in ACCESSORY mode. ACCESSORY
MODE ACTIVE will display on the Driver Information
Center (DIC). This mode allows you to use things
like the radio and the windshield wipers while the engine
is off. Use ACCESSORY if you must have your vehicle
in motion while the engine is off, for example, if your
vehicle is being pushed or towed. If the door is
open while in ACCESSORY, the key in reminder chime
will sound continuously.
Retained Accessory Power (RAP)
The following accessories on your vehicle may be used
for up to 10 minutes after the engine is turned off:
·Radio
·Power Windows
·Audio Steering Wheel Controls
Power to these accessories stops after 10 minutes or if
a door is opened. If you want power for another
10 minutes, close all the doors and press the
OFF/ACCESSORY button to place the vehicle in
ACCESSORY mode. Press the button again and the
vehicle will return to RAP.
Starting Your Engine
Move your shift lever to PARK (P) or NEUTRAL (N).
Your engine will not start in any other position ± that is
a safety feature. To restart when you are already
moving, use NEUTRAL (N) only.
The keyless access transmitter must be in the vehicle
for the ignition to work.
Notice:Do not try to shift to PARK (P) if your
vehicle is moving. If you do, you could damage the
transmission. Shift to PARK (P) only when your
vehicle is stopped.
1. With your foot on the brake pedal, press the
START button. When the engine begins cranking,
let go of the button. The idle speed will go down as
your engine gets warm.
If the battery in the keyless access transmitter is
weak, the DIC will display FOB BATTERY
LOW. You can still drive the vehicle. See ªBattery
Replacementº under
Keyless Access System
Operation on page 2-4for more information.
