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.
