Airbag system
Monitoring the
Advanced Airbag System
‘oring indicator light
Two separate indicators monitor the function of
the Advanced Airbag System: the ka light and
the PASSENGER AIR BAG OFF light.
The Advanced Airbag System as well as the side
airbags and side curtain airbags with ejection
mitigation features (including the electronic con-
trol unit, sensors and system wiring) are all
monitored continuously to make sure that they
are functioning properly whenever the ignition is
on. Every time you turn on the ignition, the air-
bag system indicator light ka will come on fora
few seconds (function check).
The system must be inspected when the
indicator light Ba:
— does not come on when the ignition is switched
on,
— does not go out a few seconds after you have
switched on the ignition, or
— comes on while driving.
If an airbag system malfunction is detected, the
indicator light will come on to serve as a constant
reminder to have the system inspected immedi-
ately.
If a malfunction occurs that turns the front air-
bag on the passenger side off, the PASSENGER
AIR BAG OFF light will come on and stay on
whenever the ignition is on.
ZA\ WARNING
An airbag system that is not functioning prop-
erly cannot provide supplemental protection
in a frontal crash.
- If the airbag indicator light > page 238
comes when the vehicle is being used, have
the system inspected immediately by your
authorized Audi dealer. It is possible that
the airbag will inflate when it is not sup-
posed to, or will not inflate when it should.
PASSENGER AIR BAG OFF light
B8V-0215
Fig. 218 Center console: passenger airbag off warning
light
The PASSENGER AIR BAG OFF light is located in
the center of the instrument panel > fig. 218.
The PASSENGER AIR BAG OFF light will come on
and stay on to tell you when the front Advanced
Airbag on the passenger side has been turned off
by the electronic control unit. If the bulb for the
PASSENGER AIR BAG OFF light burns out, the
airbag indicator light 2 will come on to signal a
malfunction in the Advanced Airbag System. Al-
though the burned-out bulb will not change the
way the front passenger's frontal airbag works, it
will no longer be possible to use the PASSENGER
AIR BAG OFF light to make sure that the airbag
on/off status is correct for the occupant on the
front passenger seat. Have the airbag system in-
spected immediately by your authorized Audi
dealer.
The PASSENGER AIR BAG OFF light will blink
for about 5 seconds when:
— the ignition is switched on and
— the capacitive passenger detection system,
which switches the front seat passenger's fron-
tal Advanced Airbag on and off, detects a
change in the status of the front passenger
seat.
As soon as the PASSENGER AIR BAG OFF light
stops blinking, always make sure that the airbag
status
(on or off) as shown by the PASSENGER
AIR BAG OFF light is proper for the age, size and
electrical capacitance of the person occupying
the front passenger seat. Always make sure that
the safety belt for the front passenger seat is
properly fastened.
