extra. On vehicles so equipped, the alarm is
automatically set by locking the driver’s or
front passenger’s door with the key. After a
brief delay (approximately 20 seconds), the
alarm will be set off if the doors, bonnet or
tailgate are opened.
The only way to disarm the alarm system is
by unlocking one of the front doors with the
key. Even if the key is used to open the
tailgate, if the alarm is set it will go off.
