S
(Panic): If your vehicle has this feature, press
this button to turn on the hazard warning
flashers. The hazard warning lamps will flash for
about 28 seconds. Press this button again to
turn off the hazard warning lamps.
The lock, unlock, and panic buttons, on the
remote keyless entry transmitter, will not operate
while the key is in the ignition. The theft-deterrent
system will not activate while the key is in the
ignition.
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 the remote
keyless entry transmitter should last about
two years.
The battery is weak if the LED light fails to
illuminate or if the transmitter will not work at the
normal operating range. If you have to get
close to your vehicle before the transmitter works,
it is 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.
