Changes to the vehicle interior, e.g. the use of seat covers, and open
windows, could impair the function
of passenger compartment
monitoring.

sounder, and the hazard warning
lights flash simultaneously. The

If the vehicle battery is disconnected
or its power supply is interrupted, the
alarm siren will be triggered. First
deactivate the anti-theft alarm system if the vehicle battery must be
