Car Finder
Press the button twice within three seconds. The horn will sound
and the turn signals will flash. We recommend you use this
method to locate your vehicle, rather than using the panic alarm.
Sounding a Panic Alarm
Press the button to activate the alarm. Press the button again
or switch the ignition on to deactivate.
Note: The panic alarm will only operate when the ignition is off.
REPLACING A LOST KEY OR REMOTE CONTROL
You can purchase replacement or additional keys or remote controls from
an authorized dealer. A dealer can program the transmitters to your
vehicle or you may be able to program them yourself. See the Security
chapter for information on programming your transmitters.
