2-7 Leaving Your Vehicle
If you are leaving the vehicle, open the door, set the
locks from the inside, get out and close the door.
Remote Keyless Entry (RKE) System
If your vehicle has this
option, you can lock and
unlock your doors, or
unlock your trunk from
about 3 feet (1 m) up to
30 feet (9 m) away using
the remote keyless entry
transmitter supplied with
your vehicle.
Your remote keyless entry transmitter operates on a
radio frequency subject to Federal Communications
Commission (FCC) Rules and with Industry Canada.
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
(1) this device may not cause harmful interference, and
(2) this device must accept any interference received,
including interference that may cause undesired operation.This device complies with RSS
-210 of Industry Canada.
Operation is subject to the following two conditions:
(1) this device may not cause interference, and (2) this
device must accept any interference received, including
interference that may cause undesired operation of
the device.
Changes or modifications to this system by other than an
authorized service facility could void authorization to
use this equipment.
This system has a range of about 3 feet (1 m) up to
30 feet (9 m). At times you may notice a decrease in
range. This is normal for any remote keyless entry
transmitter. If the transmitter does not work or if you
have to stand closer to your vehicle for the transmitter to
work, try this:

Check to determine if battery replacement is
necessary. See the instructions that follow.

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.

If you're still having trouble, see your dealer or a
qualified technician for service.

2-8 Operation
When you press this symbol to unlock the driver's
door, the parking lamps on your vehicle will blink twice.
(You can program your vehicle so the parking lamps
will not flash. For more information, see ªLock/Unlock
Confirmationº in the Index.) Pressing this symbol again
within five seconds will unlock the other doors. Pressing
this symbol will also disarm the theft
-deterrent system
(if equipped) and turn on the interior lamps at night.
When you press this symbol to lock the doors, the
parking lamps will blink once. (You can program your
vehicle so the parking lamps will not flash. For more
information, see ªLock/Unlock Confirmationº in the
Index.) This also arms the theft
-deterrent system (if
equipped).
Press this symbol to open the trunk. (The VALET
lockout button must be off for this feature to work.)
Press this button to open the fuel door. (The VALET
lockout button must be off for this feature to work.)
The remote keyless entry transmitter can also be used to
recall the memory settings for up to two drivers. For
more information, see ªMemory Seat and Mirrorsº in
the Index.
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. Once your dealer has
coded the new transmitter, the lost transmitter will not
unlock your vehicle. Each vehicle can have only four
transmitters matched to it.
Battery Replacement
Under normal use, the battery in your remote keyless
entry transmitter should last about four 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.
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.
