• make sure that the safety belt tens ion sensor is not blocked.
Shake the safety belt latch on the front passenger seatback and forth;
• If a strap or tether is being used to t ie the child safety seat to the
front passenger seat, make sure that it is not so tight that it causes
t he weight-sensing mat to meas ure more weight than is actua lly on
the seat .
If the PASSENGER AIR BAG OFF l ight still doe s not come on and
does not stay on cont inuously (when the ignition is switched on),
• take the child restraint off the f ront passenger seat and install it
properly at one of the rear seat positions . Have the airbag sys tem
inspected by your authori zed Audi dealer immediately .
• move the child to a rea r seat position and ma ke s ure that the child
is properly restrained in a ch ild restraint that is appropriate for its
size and age .
The
PA SSENG ER AIR BAG OFF light should NOT come on when the
ignition is on and an adult is sitting i n a proper seating position on the
front passenger seat . If the
PASSENGER AIR BAG OFF light comes on
and stays on or flashes for abo ut 5 seconds while driving, under these
circumstances, make sure that:
• the adult on the front passenger seat is properly seated on the
c en ter of the sea t cushion wi th his or her back up against the backrest
and the backrest is not reclined::::;,

An a irbag syst em that is not fun ction ing properly cannot provide
supplemental protect ion in a frontal crash.
• If th e airbag indic ator light comes on , it means th at there may
be something wrong with the Advanc ed Airbag S ystem . It i s
poss ible that th e airbag will inflat e when it is not suppos ed to , or
will not inflate when it should.
• Have the a irb ag system inspected immediately by your autho ­
rized Audi dealer .
& WARNING
If the front airb ag inflate s, a child without a child restraint, or in
a rearwa rd -facing child safet y seat, o r in a fo rwa rd-facing child

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
Perchlorate Material -special handling may apply, see
www.dtsc.ca.gov/hazardouswas te/perchlorate . When the vehicle or
parts of the restraint system including airbag modules and safety
belts with pretensioners are scrapped, all applicable laws and regu la­
tions mus t be observed. Your authorized Audi dealer is familiar w ith
these requirements and we recommend that you have your dealer

Airbag system
Side airbags
Description of side airbags
The airbag system can provide supplemental protection
to properly restrained occupants.
Fig. 204 Side airbag
location in the driver's
seat
The side airbags are located in the sides of the front seat backrests
~ fig. 204 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 value 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 229, "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 201, "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 229.
• 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.

& WARNING (continued)
• Always use the built-in coat hooks only for lightweight
clothing. Never leave any heavy or sharp-edged objects in the
pockets that may interfere with side airbag deployment and can
cause personal injury in an accident.
• Always prevent the side airbags from being damaged by heavy
objects knocking against or hitting the sides of the seatbacks.
• The airbag system can only be triggered once. If the airbag has
been triggered, the system must be replaced by an authorized
Audi dealership.
• Damage (cracks, deep scratches etc.) to the original seat covers
or to the seam in the area of the side airbag module must always
be repaired immediately by an authorized Audi dealer.
• If children are seated improperly, their risk of injury increases
in the case of an accident =:>
page 233, "Child Safety".
• Never attempt to modify any components of the airbag system
in any way.
• In a side collision, side airbags will not function properly if
sensors cannot correctly measure increasing air pressure inside
the doors when air escapes through larger, unclosed openings in
the door panel.
- Never drive with interior door trim panels removed.
- Never drive when parts have been removed from the inside
door panel and the openings they leave have not been properly
closed.
- Never drive when loudspeakers in the doors have been
removed unless the speaker holes have been properly closed.
- Always make certain that openings are covered or filled if
additional speakers or other equipment is installed in the
inside door panels.
- Always have work on the doors done by an authorized Audi
dealer or qualified workshop. •
Side curtain airbags
Description of side curtain airbags
The side curtain airbags can provide supplemental
protection to properly restrained occupants.
Fig . 206 Side curtain
airbags , driver 's side:

The side curtain airbags are located on both sides of the interio r
above the front and rear side windows =:> fig. 206 . They are identif ied
by the wo rd "AIRBAG" on the windshield frame and the cente r roof
pillar.
Th e side curtain airbag system supplements the safety belts and can
he lp to reduce the risk of injury for occupants' heads a nd upper torso
on the side of the vehicle th at is struck in a si de collis ion . The side
curtain airbag inflates in side impacts and only when t he veh icle
acceleration registered by the control u nit is high enoug h.
If this rate
is below the reference va lue programmed in to the control unit, the
side airbags wi ll not be triggered, even though the car may be badly
damaged as a result of the collision. It is not possible to define an
airbag triggering range that wi ll cover every possible angle of impact,
since the circumstances will vary consid erably between one collision
and another. Important factors include, for example, the nature

and for the different models of the same kind of child restraint
offered by child restraint manufacturers.
The weight ranges for the individual types, makes and models of ch ild
restraints that the NHTSA has specified in the Safety Standard
together with the weight ranges of typical infants and typical 1 year­
old child have been stored in the control unit of the Advanced Airbag
System. When a child restraint is being used on the front passenger
seat with a typical 1 year-old chi ld, the Advanced Airbag System
compares the weight meas ured by the weight sensing mat with the
information stored in the electronic control unit .
The electronic contro l unit a lso registers the tension on the front
passenger safety belt. The tension on the safety belt for the front
passenger seat will be different for an adult who is properly using the
safety belt as compared to the tension on the belt when it is used to
attach a child restraint to the seat . The sensor below the latch for the
safety belt for the front seat passenger measures the tension on the
belt. The input from this sensor is then used with the weight to
"decide", whether there is a child restraint with a typical 1 year-old
child on the front passenger seat and whether or not the airbag must
be turned off .•
Child restraints and Advanced Airbags
Regardless of the child restraint that you use, ma ke sure that it has
been certified to meet United States Federal Motor Vehicle Safety
Standards and has been ce rtified by its manufacturer for use with an
airbag . Always be sure that the child restraint is properly installed at
one of the rear seating positions. If in exceptional circumstances you
must use it on the front passenger seat, carefully read all of the infor­
mation on ch ild safety and Advanced Airbags and heed all of the
app licab le WARNINGS. Make certain that the child restra int is
correctly recognized by the weight-sensing mat inside the front
passenger seat, that the front passenger airbag is turned off and that
the airbag status is always correctly signaled by the
PASSENGER AIR
BAG OFF
light.
Controls and equip­ ment Safety first Vehicle operation
Many types and models of child restra
ints have been available over
t he years, new models are introduced reg ularly incorpo rating new
and improved designs and older models are taken out of product ion.
Chi ld restraints are not standardized. Child restraints of the same
type typ ically have d ifferent weights and sizes and differe nt 'foot­
prints,' the size and shape of the bottom of the child restraint that
sits on the seat, when they are installed on a vehicle seat . These
differences make it virtually impossib le to certify compliance with
t he requirements for advanced airbags with each and every chil d
restra int that has ever been sold in the past or will be sold over the
course of the useful life of your vehicle.
For this reason, the United States Nationa l Highway Traffic Safety
Administration has published a list of specific type, makes and
mode ls of child restra ints that must be used to cert ify compliance of
the Advanced Airbag System in yo ur vehicle with the suppression
requirements of Federal Motor Veh icle Safety Standard 208. These
child restraints are:

Intelligent technology
Notice about data recorded by
vehicle control modules
Your vehicle is not equipped with an Event Data Recorder (EDR),
installed by some manufacturers for the express purpose of
capturing data for retrieval after an accident or crash event. ED Rs are
sometimes called "crash recorders".
Some state laws restrict the retrieval or downloading of data stored
by ED Rs that were installed in a vehicle for the express purpose of
retrieving data after an accident or crash event without the owner's
consent.
Although your vehicle is not equipped with an EDR, it is equipped w ith
a number of electronic control modu les for various vehicle systems
such as, for example, engine function, emission control, as well as for
the airbags and safety belts.
T hese electronic control modules also record vehicle-re lated data
during normal vehicle operation for diagnostic and repair purposes .
Th e recording capacity of the e lectronic control modu les is limited to
data (no sound is recorded) and only a sma ll amount of data is actu­
ally recorded over a very limited period of time and stored when a
system fault or other condition is sensed by a control unit. Some of
the data then stored may relate to vehicle speed, direction, braking
as well as restraint system use and performance in the event of a
crash or other condition. Stored data can only be read and down­
loaded with special equipment.
Electronic Stabilization Program
(ESP)
General information
The ESP improves the vehicle stability.
Fig. 222 Center
console with ESP
switch
ESP is des igned to help you maintain vehicle control in situations
where the car approaches the limits of "grip", especia lly when accel­
erating and cornering. ESP reduces the risk of skidd ing and imp roves
stability under all road conditions.
Th e system operates across the entire speed range in combination
with the ABS system. If the Anti-Lock Brake System (ABS) malfunc­
tions, the ESP will also shut down.
How the system works
The Anti-Lock Brake System (ABS), Electronic Differential Lock (EDL)
and the Anti-Slip Regulation System (ASR) are integrated in the elec­
tronic stabilization program. In addition to the data provided by
these funct ions, the ESP control unit requires additional measure­
ment data provided by high performance sensors. The rotational
speed of the vehicle about its vertical axis, veh icle acceleration in the ...
