Owner's Manual The front-passenger front airbag and front-passenger kneebag are
disabled during the journey, although:
R an adult
or
R a person of the corresponding stature is on the front-passenger seat
If additional forces are applied to the seat, the weight the system
detects may be too low.
G WARNING

PASSENGER AIR BAG ON indicator lamps must light up simulta-
neously for approximately six seconds
R The PASSENGER AIR BAG OFF indicator lamp must then light up
and remain lit after the self-diagnosis. If the indicator lamp is on,
the automatic front-passenger front airbag deactivation system
