PASSIVE SAFETY EQUIPMENT
The MEGANE II has equipment also found on the LAGUNA II and VEL SATIS, namely:
– Front seat chest side airbag.
– Front seat type BXX double pretensioner.
– Driver's seat position sensor for adaptive airbag.
– Three-point rear centre seat belt.
– Front and rear Isofix mountings.
INNOVATIONS:
– Passenger airbag inhibition switch
– Anti-skid airbag in the seat along with a buckle pretensioner on the
front seat in type CMXX MEGANE II.
In the text, this airbag is referred to as the:
SEAT-CUSHION AIRBAG/DRIVER'S SEAT LAP BELT.
Via the same trigger line, the ACU 4 Vdiag 04 computer controls either the seat-cushion (anti-
skid) airbag or the driver's seat lap belt pretensioner:
The configuration for type B is: Driver's seat lap belt pretensioner.
The configuration for type C is: Driver's seat-cushion airbag.
Both features are never found on the same vehicle because they use the same ignition
line.
