Operating it from outside simulta-
neously activates the anti-theft system,
which prevents the doors from being
unlocked via the door lock buttons or
the door release handles. The alarm
system is also armed or disarmed.
There is an extended-life battery
in every master key with remote
control that is charged automatically in
the ignition lock as you drive.
For this reason, if you have a master
key with remote control that is other-
wise not used, use that key at least
once every year while driving for an
extended period to charge the bat-
tery.<
The central locking system unlocks
automatically in the event of an acci-
dent. In addition, the hazard warning
flashers and interior lamps come on.
