Servicing Your Airbag-Equipped
Vehicle
Airbags affect how your vehicle should be
serviced. There are parts of the airbag system in
several places around your vehicle. You do
not want the system to inate while someone is
working on your vehicle. Your dealer and the
service manual have information about servicing
your vehicle and the airbag system. To purchase a
service manual, seeService Publications
Ordering Information on page 497.
{CAUTION:
For up to 10 seconds, after the ignition is
turned off and the battery is disconnected,
an airbag can still inate during improper
service. You can be injured if you are
close to an airbag when it inates. Avoid
yellow connectors. They are probably part
of the airbag system. Be sure to follow
proper service procedures, and make sure
the person performing work for you is
qualied to do so.
The airbag system does not need regular
maintenance.

If you ever notice a decrease in the keyless
access 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 “Battery Replacement”
underKeyless Access System Operation on
page 68.
Check to make sure that an electronic device
such as a cellular phone or lap top computer
is not causing interference.
If you are still having trouble, see your dealer
or a qualied 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 with
two transmitters, and up
to four can be matched
to your vehicle. See
“Matching Transmitter(s)
to Your Vehicle” later
in this section.
Q(Lock):Press this button to lock the doors.
The indicator 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 FOB 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 at object with a thin edge into the
slot on the side of the transmitter and
separate the bottom half from the top half.
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.

To stop the trunk lid while it is closing, do one of
the following:
Press the trunk lock release button located on
the instrument panel.
Use the vehicle key.
Squeeze the trunk release sensor located on
the rear of the trunk lid.
Press the button with the trunk symbol on the
keyless access transmitter.
Press the trunk close button on the underside
of the trunk lid.
To begin opening the trunk from the stopped
position, use any of the methods above, except
pressing the trunk close button.
To resume closing the power trunk lid, press the
trunk close button on the underside of the trunk lid.
If the vehicle has lost battery power, you can
still open the trunk using the key.The key cylinder is located behind a cover on the
lower rear fascia on the driver’s side of the
vehicle. Open the door to access the key cylinder.
The key is located inside the keyless access
transmitter. SeeKeys on page 65for more
information.

Power Windows
The power window
switches are located on
each door near the
armrest.
Press the up or down arrows on the switches to
raise or lower the windows.
Your vehicle has Retained Accessory Power
(RAP) that allows you to use the power windows
once the ignition has been turned off. For
more information, seeRetained Accessory Power
(RAP) on page 89.
Power Window Initialize
After a power reconnect such as battery
replacement, the express-up and index-up features
will not function until the system is initialized.
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.
The express-up system must be initialized to
operate the windows 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.

Arming the System
Use one of the three 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. Remove the keyless access transmitter
from the interior of the vehicle and 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 and arm the
system when you exit the vehicle. SeeDIC
Vehicle Personalization on page 220.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.
85

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 Acc. button to place the vehicle in accessory
mode. Press the button again and the vehicle
will return to RAP.
Starting the Engine
Move the shift lever to PARK (P) or NEUTRAL (N).
To restart when you are already moving, use
NEUTRAL (N).
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.
The keyless access transmitter must be inside the
vehicle for the ignition to work.
Cell phone chargers can interfere with the
operation of the Keyless Access System. Battery
chargers should not be plugged in when starting
or turning off the engine.

To start you vehicle, do the following:
1. With your foot on the brake pedal, press the
START button located on the instrument
panel.
If there is not a keyless access transmitter in
the vehicle or if there is something causing
interference with it, the DIC will display
NO FOB DETECTED. SeeDIC Warnings and
Messages on page 206for more information.
2. When the engine begins cranking, let go of
the button and the engine cranks automatically
until it starts. If the battery in the keyless
access transmitter is weak, the DIC displays
FOB BATTERY LOW. You can still drive
the vehicle.
See “Battery Replacement” underKeyless
Access System Operation on page 68for more
information. If the fob battery is dead, you
need to insert the fob into the fob slot to enable
engine starting. See″No Fobs Detected″
underDIC Warnings and Messages on
page 206.3. Do not race the engine immediately after
starting it. Operate the engine and
transmission gently until the oil warms up and
lubricates all moving parts.
4. If the engine does not start and no DIC
message is displayed, wait 15 seconds
before trying again to let the cranking motor
cool down.
If the engine does not start after 5-10 seconds,
especially in very cold weather (below 0°F
or−18°C), it could be ooded with too much
gasoline. Try pushing the accelerator pedal all
the way to the oor while cranking for up to
15 seconds maximum. Wait at least
15 seconds between each try, to allow the
cranking motor to cool down. When the engine
starts, let go of the accelerator. If the vehicle
starts briey but then stops again, do the same
thing. This clears the extra gasoline from the
engine.
