Notice
Changes to the vehicle interior, e.g.
the use of seat covers, and open
windows, could impair the function
of passenger compartment
monitoring.
Deactivation
Unlocking the vehicle or switching on
the ignition deactivates the anti-theft
alarm system. Hazard warning lights
flash once to confirm deactivation.

If the alarm has been triggered,
unlocking the vehicle with the key
will not stop the alarm siren. To stop the siren, switch on the ignition. The
hazard warning lights will not flash
upon deactivation if the alarm has
been triggered.
