nied by optical warning signals for about five minutes when the vehicle is
locked and the following unauthorised actions are taken:
xWhen the door is mechanically unlocked using the vehicle key without
turning the ignition within the following 15 seconds.
xA door is opened.
xThe bonnet is opened.
xThe tailgate is opened.
xWhen the ignition is switched on with a non-authorised key.
xWhen the vehicle battery is disconnected.
xWhen there is movement inside the vehicle (vehicles with interior moni-
toring).
xWhen the vehicle is towed (vehicles with anti-tow system)
xWhen the vehicle is lifted (vehicles with anti-tow system).
xTransporting the vehicle on a ferry or by railroad (vehicles with an anti-tow
system or passenger compartment monitoring).
xUnhitch a trailer connected to the antitheft alarm Ÿpage 260.
How to turn OFF the alarm
Unlock the vehicle with the unlocking button on the key or turn on the ignition
with a valid key.
Note
The alarm will be triggered once more when anybody enters the same zone of
surveillance or any other zone. If, for example, after opening a door, the tail-
gate is also opened.
Note
The antitheft alarm is not activated when the vehicle is locked from within
using the central locking button .
Note
If the driver's door is unlocked mechanically with the key, only the driver's
door is unlocked, the rest of the doors remain locked. Only when the ignition
has been turned on will the other doors be available - but not unlocked - and
the central locking button activated.
Note
If the vehicle battery is run down or flat then the antitheft alarm will not
operate correctly.
