Airbag system -----------------=--=---
& WARNING (co ntinued )
• Always install forward or rear-facing child safety seats on the
rear seat - even with an Advanced Airbag System .
• If you must install a rearward-facing child safety seat on the
front passenger seat because of exceptional circum stances and
the PASSENGER AIR BAG OFF light does not appear and stay on ,
immediately install the rear-facing child safety seat in a rear
seating pos ition and have the airbag system inspected by your
authorized Audi dealer.
• A tight tether or other strap on a rearward-facing child
restraint attached to the front passenger seat can put too much
pressure on the weight-sensing mat in the seat and register more
weight than is actually on the seat. The heavier weight registered can make the system work as though an adult were on the seat
and deploy the Advan ced Airbag when it must be suppres sed
caus ing serious or e ven fatal injury to the child.
• If, in exceptional circumstances, you must install a forward
facing child restraint on the front passenger seat, always move
the seat into its rearmost position in the seat' s fore and aft adju st
ment range , as far away from the airbag as possible . The backrest
must be adjusted to an upright position. Make sure that the PASSENGER AIR BAG OFF light comes on and stays on all the time
whenever the ignition is switched on.
& WARNING
• If the PASSENGER AIR BAG OFF light doe s not go out when an
adult is sitting on the front passenger seat after taking the steps
described above, make sure the adult is properly seated and
restrained at one of the rear seating posit ions.
• Have the airbag system inspected by your authorized Audi
dealer before transporting anyone on the front passenger seat.

Other things that can affect Advanced
Airbag performance
Chang ing the vehicle's suspension system can change the way that
th e Adva nced Airbag System pe rforms i n a cr ash. Fo r examp le, us in g
t ire-rim combinations not approved by Audi, lowering the vehicle,
c hang ing the stiffn e ss o f th e suspension, incl uding t he sp rings,
suspension struts , shock absorbers etc. can change t he forces that
are meas ured by the a irbag sensors an d sent to the elect ronic contro l
unit . Some suspension c hanges can, fo r example, increase the force
levels meas ure d by the senso rs and make the airbag system deploy in
crashes in which i t would not deploy if the changes had not been
ma de. Other ki nds of changes may reduce the force levels meas ure d
by th e sensors a nd p rev ent the airbag from dep loying when it should.
T he sensors in the safety belt b uckle for the drive r and front
p assenge r se at tell the e lec tron ic co ntrol mo dule if the safety bel t i s
latched or not. If the safety belt is being used, the front a irbag w ill
dep loy at a sligh tly higher rate o f vehicle deceler ation t han if t he
sa fety belt is not be ing used . Therefo re, in a pa rt icu lar collis io n, it is
possible that an a irbag w ill not dep loy at a seating posi tion where the .,_

safety belt is being used but will inflate at the position where the
safety belt is not being used. It is impo rtant that nothing in terfere
with the safety belt buckles so that the sensors can send the correct information about safety belt use to the electronic control unit.
& WARNING
Changing the vehicle's suspension including use of unapproved
tire-rim combinations can change Advanced Airbag performance
and increase the risk of serious personal injury in a crash.
• Never install suspension components that do not have the
same performance characteristics as the components originally
installed on your vehicle.
• Never use tire-rim combinations that have not been approved
by Audi.
& WARNING
Items stored between the safety belt buckle and the center
console can cause the sensors in the buckle to send the wrong
information to the electronic control module and prevent the
Advanced Airbag System from working properly.
• Always make sure that nothing can interfere with the safety
belt buckles and that they are not obstructed .
W For the sake of the environment
Undeployed airbag modules and pretensioners might be classified as

Airbag system
Side airbags
Description of side airbags
The airbag system can provide supplemental protection
to properly restrained occupants.
Fig. 202 Side airbag
location in the driver's
seat
The side airbags are located in the sides of the front seat backrests
~ fig. 202 and the rear backrest* facing the doors . They are identi
fied by the word "AIRBAG" .
The side airbag system basically consists of:
• the electronic control module and external side impact se nsors
• the two side airbags located in the sides of the front backrests
• two rear side airbags (as an ordered
option)
• the airbag warning light in the instrument cluster.
Th e airbag system is monitored elect ronically to make certain that it
is functioning properly at all times. Each time you turn on the igni
tion, the airbag system indicator light will come on for a few seconds
(self d iagnostics).
The side airbag system supp lements the safety belts and can he lp to
reduce the risk of injury to the dr iver 's, front and rear* passenger 's
upper torso on the side of the vehicle that is struck in a side collision.
The airbag deploys on ly in s ide impacts and only when the vehicle
acceleration registered by the control unit is high enough. If this rate

is below the reference va lue programmed into the cont rol unit, the
side airba gs w ill no t be triggered, even though t he car may be b ad ly
damaged as a result of the collision. It is not possible to define an
airbag tr iggering range that w ill cover every possible angle of impact,
since the circumstances will vary considerably between one collision
and another . Important factors include, for example, the nature
(hard or soft) of the impacting object, the angle of impact, vehicle
speed, etc.~
page 227, "Important safety instructions on the side
airbag system" .
Aside from the ir normal safety function, safety be lts work to help
keep the d river or front passenger in posit ion in the event of a side
co llision so that the side airbags can provide protection.
The airbag system is
not a substitute for your safety belt. Rather, it is
part of the ove rall occupant restraint system in your veh icle. Always
remember that the side airbag system can only help to protect you if
you a re wearing your safety belt and wearing it p rope rly. This is
another reason why you shou ld always wear your safety belts, not just
because the law requires you to do so~
page 199, "General no tes" .
It is important to remembe r that wh ile the supp lemental s ide airbag
system is designed to reduce the likelihood of se rious injuries, ot her
injuries, fo r examp le, swe lling, bru ising, and minor abras ions can
also be associated with deployed side airbags . Remember too, side
airbags will dep loy only once and only in certai n kinds of accidents -
your safety belts are always there to offer protection.
Vehicle damage, repair costs or even the lack of veh icle damage a re
not necessar ily an ind ication of over-sensitive or failed airbag activa
t ion . In some collisions, both front a nd side airbags may inflate .
Remember too, that a irbags will deploy only once and only in certa in
kinds of collisions -your safety belts are a lways there to offer protec
tion in those acc idents in w hich airbags a re not supposed to deploy or
when they have already deployed.
The side airbag system will not deploy :
• when the ignition is turned off
• in side collisions when the acceleration measured by the sensor is
too low •
in front-end collis ions
• in rea r-end collisions
• in rollovers .
In some types of accidents the front a irbags, side curtain airbags and
side airbags may be triggered together.
& WARNING
• Safet y belts and the airbag s ystem will only provide protection
when o ccupants are in the proper seating position ~
page 227.
• If the airbag indicator light comes on when the vehicle i s being
used, have th e system inspe cted immediately by your authoriz ed
Audi dealer. The airbag may not work prope rly when the vehicle
a cceleration in a side collision is high enough to activate the
ai rbag. •
How supplemental side airbags work
Side airbags deploy instantly and can help reduce the risk
of upper torso injuries for occupants who are pro perly
restrained.
