Operation
When you press UNLOCK, the driver's door will
unlock automatically. If you press UNLOCK again
within five seconds, all doors will unlock. All doors
will lock when LOCK is pressed. The interior lamps
will come on whenever you lock or unlock the doors.
See "Keyless Illumination" in the Index. Pressing
REAR 2X twice within three seconds, will unlock the
hatch or rear cargo doors.
Matching Transmitter(s) To Your Vehicle
Each f6ifiote 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 only two transmitters
matched to it.
