DE-ACTIVATING PASSENGER AIR-BAG
Passenger air-bag can be disabled from instrument cluster menu directly by the driver.
Air-bag central unit will send a message through “B” Can line to instrument cluster which activates a yellow warning lamp and
a message on display screen (comfort). If passenger air-bag is enabled, the warning lamp will flash on going on and then go off.

The electronic control unit is located on the floor at the side of the driver’s seat between the gearshift lever and the parking brake
lever; it is supplied at 12 Volt by a key-operated device, but it is still in a condition to be able to work for about 200 msec after
a power cut off.
This is possible due to the presence of a buffer condenser inside which accumulates electric energy for normal operation of the
control unit and generate the signal for triggering the explosive capsule.
This way system operation is guaranteed if the crash causes a power system failure (for example damage or breakage of the
battery, power cable cut-off etc.).

!
The control unit must be directed with the arrow printed on the sticker facing the vehicle direction of travel. This is
absolutely necessary as it determines the direction in which the deceleration sensor reads the values for defining the
crash condition and thus triggering the air bag.
