Remote Keyless Entry System
If equipped, the keyless entry system 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 interference, and
2. This device must accept any interference received,
including interference that may cause undesired
operation of the device.
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. 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 “Battery Replacement” under
Remote Keyless Entry System Operation on
page 2-5.
If you are still having trouble, see your dealer or a
qualified technician for service.

Remote Keyless Entry System
Operation
If your vehicle has this feature, you can lock and unlock
your doors from about
3 feet (4 m) up to 30 feet (9 m)
away using the remote keyless entry transmitter supplied
with your vehicle.
UNLOCK: When you
press UNLOCK, the
driver’s door will unlock
automatically, the parking
lamps will flash and the
interior lights will go on.
If you press UNLOCK again within three seconds,
all doors will unlock.
LOCK: Press LOCK to lock all the doors. Press LOCK
again within three seconds and the horn will chirp.
REAR 2X: When you press the REAR button twice
within three seconds to unlock the rear hatch or cargo
doors, the parking lamps
will flash and the interior lights
will go on. If the engine is running, the automatic
transmission must be in PARK (P) or NEUTRAL (N) for
the REAR
2X button to operate.
& (Panic Alarm): When this button is pressed,
the horn will sound and the headlamps and taillamps
will flash for up to
30 seconds. This can be turned off by
pressing the panic button again, waiting for
30 seconds,
or starting the vehicle.
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 two 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.
To replace the battery, do the following:
Notices 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.
2.
3. Insert
a thin object like a dime to separate the
bottom of the transmitter from the top.
Remove the battery and replace it with a new one,
making sure the positive
(+) side of the battery is
facing down. Use one Panasonic@ three-volt,
type CR2032, or equivalent battery.
Snap the top and bottom together.
