At times you may notice a decrease in range. This is
normal for any remote keyless entry system. If the
transmitter does not work or if you have to stand closer
to your vehicle for the transmitter to work, try this:
·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
Remote Keyless Entry System Operation on
page 2-5.
·If you are still having trouble, see your dealer or a
quali®ed technician for service.
Remote Keyless Entry System

For more information, see
DIC Vehicle Personalization
on page 3-67andMemory Seat, Mirrors and Steering
Wheel on page 2-55.
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.
Vehicles are delivered with two transmitters. See your
dealer for information on how to obtain additional
transmitters.

Never store objects on the rear shelf because they may
get caught in the sunshade or be tossed about in
your vehicle.
Manual Rear Side Door Sunshade
Your vehicle may have manual rear side door
sunshades. To use the sunshades, lower the side
windows and hook the top edge of the retractable
sunshades over the edge of the windows and raise the
windows. To remove the shades, lower the windows
and the hooks will disengage automatically.
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.
The SECURITY light is
located on the instrument
panel cluster.
If the ignition is off and any door is open, the SECURITY
light will ¯ash, reminding you to arm the system.To arm the system, do the following:
1. Open the door.
2. Lock the door using the power door lock switch with
the door open or the remote keyless entry
transmitter. The SECURITY light should come on
and stay on.
3. Close all the doors. The SECURITY light should go
off within approximately 30 seconds.
If a door or the trunk is opened without a key or a
remote keyless entry transmitter, the horn will sound
and the lamps will ¯ash for about 30 seconds.
Remember, the theft-deterrent system won't arm if you
lock the doors with a key or use the manual door
lock. It activates only if you use a power door lock with
the door open or the remote keyless entry transmitter.
To avoid activating the alarm by accident do the
following:
·The vehicle should be locked with the door key or
the manual door lock after the doors are closed if
you don't want to arm the theft-deterrent system.
·Always unlock a door with a key or use the remote
keyless entry transmitter system. Pressing the
unlock button on the remote keyless entry
transmitter disables the theft-deterrent system.
Unlocking a door any other way will activate
the alarm when a door or the trunk is opened.
2-19

If you activate the alarm by accident, unlock the driver's
door with your key. You can also turn off the alarm by
using the unlock button on the remote keyless entry
transmitter system, or by starting the car with a valid key.
Changes or modi®cations made to this system by other
than an authorized service facility could void
authorization to use the theft system.
Testing the Alarm
1. From inside the vehicle, roll down the window, then
get out of the vehicle, keeping the door open.
2. From outside of the vehicle, with the door open, lock
the vehicle using the power door lock or the remote
keyless entry system and close the door. Wait 30
seconds until the SECURITY lamp goes off.
3. Reach in and unlock the door using the manual
lock and open the door. The horn will sound and
the hazard lights will ¯ash.
You can turn off the alarm by unlocking the driver's door
with your key, using the unlock button on the remote
keyless entry transmitter or by starting the car with
a valid key.
If the alarm does not sound when it should, check to
see if the horn works. The horn fuse may be blown.
To replace the fuse, see
Fuses and Circuit Breakers on
page 5-94. If the fuse does not need to be replaced,
you may need to have your vehicle serviced.To reduce the possibility of theft, always arm the
theft-deterrent system when leaving your vehicle.
Valet Lockout Switch
The valet lockout switch
is located inside the
glove box.
Press the switch to ON to disable the use of the trunk,
fuel door, garage door opener and optional cellular
telephone. The remote keyless entry transmitter cannot
open the trunk if the valet lockout switch is in ON.
Press this switch to OFF to enable the use of the trunk,
fuel door, garage door opener and optional cellular
telephone.
Locking the glove box with your key will also help to
secure your vehicle.
