Homelink®
Universal remote
control
Description
Appl ies to vehicles: with Horne Link
The Homelink universal remote control can
be programmed with the remote control for
devices that are already present.
With Home Link, you can control devices such
as the garage door, security systems, house
l ights, etc. comfortab ly from the inside of you
vehicle .
H ome Link makes it possible for you to rep lace
three differen t remote controls from dev ices
in your home with one universal remote. This
feature works for most garage door and exte­
rior door motor signals. Programming the in­
dividual remote control for your remote con ­
trol takes p lace near the center of the radiator
grille. There is a control module attached at
this location.
A one-t ime programming of the sensor must
be performed before you are able to use sys­
tems with Homelink. If the system does not
activate after performing the one-t ime pro­
gramming, check whether the system uses a rolling codec:>

the MMI*.
_& WARNING
- Never use the Homelink ® transmitter
with any garage door opener that does
have not the safety stop and reverse fea ­
ture as requ ired by federa l safety stand­
ards. This includes any garage door open­
er model manufactured before April 1,
1982.
- A garage door opener which cannot de­
tect an object, signaling the door to stop
and reverse does not meet current feder­
al safety standards. Us ing a garage door
opener without these features increases
risk of serious injury or death.

Advanced Airbag System components
The fron t passenger seat in your vehicle has a
lot of very important parts of the Advanced
Airbag System in it. These parts include the
weight-sensing mat, sensors, wiring, brack ­
ets, and more. The function of the system in
the front passenger seat is checked by the
e lectronic control u nit when the ignit ion is on .
The control un it mon itors the Advanced Air­
bag System and turns the airbag indicator
l ight on whe n a ma lfunction in t he sys tem
components is de tected. The function of the
airbag indicator light is described in greater
detai l below . Because the front passenger
seat contains important parts of the Ad ­
vanced A irbag System, you m ust take care to
prevent it from being damaged. Damage to
the seat may prevent the Advanced Airbag for
the front passenger seat from doing its job in
a crash .
The front Advanced Airb ag Sy stem
consists of the following:
- Crash sensors in the front of the veh icle that
measure veh icle acceleration/decele ration
to provide information to the Advanced Air­
bag System about the seve rity of the crash.
- An electronic co ntrol unit, with integrated
c rash se nsors for front and side impacts .
T he cont ro l unit " decides " whethe r to fire
the front airbags based on the inform ation
received from the crash senso rs . The contro l
unit a lso "decides" whether the safety belt
pretensioners should be activated .

- Improper repair or disassembly of the
front passenger and driver seat will pre­
vent the Advanced Airbag System from
functioning properly.
- Repairs to the front passenger seat must
be performed by qualified and properly
trained workshop personnel.
- Never remove the front passenger or
dr iver seat from the veh icle .
- Never remove the upholstery from the
front passenger seat.
- Never disassemble or remove parts from the seat or disconnect wires from it.
- Never carry sharp objects in your pockets
or place them on the seat. If the weight­
sensing mat in the passenger seat is punctured it cannot work properly.
- Never carry things on your lap or carry
objects on the passenger seat. Such
items can increase the weight registered
by the weight-sens ing ma t and send the
wrong info rmation to the airbag control
uni t.
- Never sto re items under the front pas·
senger seat. Parts of the Advanced Ai r­
b ag System under the p assenge r seat
cou ld be damaged, prevent ing them and
the airbag system from wo rking proper ­
ly .
- Never place seat covers or replacement
upholste ry that have not been specifical­
ly approved by A udi on the front seats.
- Seat covers can prevent the A dvanced
Air bag System from recognizing child re­
straints or occupants on the front pas­
senger seat and prevent the side airbag in the seat backrest from deploy ing prop­
erly.
- Never use c ush ions, pillows, blankets or
similar items on the front passenger
seat. The add it iona l padd ing will prevent
the weight-sensing mat in the seat from
accu rately reg iste ring the c hild restra int
or person on the seat and prevent the
Adva nce d Airb ag System from func tion­
ing properly .
-If you mus t use a child restra int on the
front passenger seat and the ch ild re- straint manufacture
r's instructions re­
qu ire the use of a towel, foam cushion or
something e lse to properly pos ition the
child restraint, make certain that the
PASSENGER AIR BAG OFF light comes
on and stays on whenever the ch ild re·
s t raint is installed on the front passen ­
ge r seat.
- If the PASSENGER AIR BAG OFF light
does not come on a nd stay on, immed i­
a tely insta ll child restrain t in a rear se at­
ing position and have the ai rbag system
inspected by your authorized A udi dealer.
How the Advanced Airbag System
components work together
The front Advanced Airbag System and the
s ide airbags supp lement the protection of­
fered by the front three-poi nt safety belts
with pretensioners and load limiters a nd the
adjustable head rest raints to help redu ce the
risk of inj ury in a wide range of accident and
c rash situations. Be s ure to read the impor ­
tant information about safety and heed the
WARNINGS in this chapter.
Deployment of the Adv a need A irba g System
and t he activation of the safety belt preten­
sioners depend on the deceleration measured
by the crash sensors and registered by the
electron ic control unit. The amount of infla­
tion of the front airbags can a lso be adapted
to the front sea t pos ition, depending on the
distance between the respect ive front seat
and the steer ing w heel or instrument panel as
registered by sensors in the seats. Crash se·
verity depends on speed and decelerat ion as
well as the mass and st iffness of t he vehicle
o r object involved in the crash .
On the passenger side, regardless of safety
belt use, the ai rbag w ill be tu rned off if the
we ight on the passenger seat is less than the
amount programmed in the e lectron ic control
u nit. The front airbag on the passenger side
will a lso be turned off if one of the child safe -
ty seats that has been certified under Federal
Motor Vehicle Safety Standard 208 has been
recogni zed on the seat . The

Monitoring the
Advanced Airbag
System
Airbag monitoring indicator light
Two separate indicators monitor the function
of the Advanced Airbag System: the airbag
monitoring indicator light and the
PAS SEN ­
GER AIR B AG OFF
light.
The Advanced Airbag System (including the
e lectronic control unit, sensor circuits and sys­
tem wiring) is monitored continuously to
make sure that it is functioning properly
whenever the ignit ion is on . Each t ime you
turn on the ignition, the
I airbag monitoring
i ndicator light w ill come o n for a few seconds
(self diagnostics) .
The system mu st be in spected when the
I indicator l ight:
- does not come on when the ignit ion is
switched on,
- does not go out a few seconds after yo u
have switched on the ignition, o r
- comes on while d riving .
If an airbag system malfunction is detected,
the indicator light will first start flashing to
catch the driver's attention and then stay on
continuously to serve as a constant reminder
to have the system inspected immediately.
If a malfunction occurs that turns the front
a irbag on the passenger side off, the
PASSEN­
GER AIR BAG OFF
li ght will come on and stay
on whenever the ignition is on.

Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced Airbag Sys­
tem performs in a crash. For example, using
tire-r im combinations not approved by Audi,
lowering the vehicle, changing the stiffness of
the suspension, including the springs, suspen­
sion struts, shock absorbers etc. can change
the forces that are measured by the airbag sensors and sent to the electronic control
unit. Some suspension changes can, for exam­
ple, increase the force levels measured by the
sensors and make the airbag system deploy in
crashes in which it would not deploy if the
changes had not been made . Other kinds of
changes may reduce the force levels meas­
ured by the sensors and prevent the airbag
from deploying when it should .
The sensors in the safety belt buckle for the
d river and front passenger seat tell the elec­
tronic control module if the safety belt is
latched or not. If the safety belt is being used,
the front airbag will deploy at a slightly high­
er rate of vehicle deceleration than if the safe ­
ty belt is not being used. Therefore, in a par­
ticular collision, it is possible that an airbag
will not deploy at a seating position where the safety belt is being used but will inflate at the
position where the safety belt is not being
used. It is important that nothing interfere
with the safety belt buckles so that the sen­
sors can send the correct information about
safety belt use to the electronic control unit.
.&_ WARNING
Changing the vehicle 's suspension includ­
ing use of unapproved tire-rim combina­
tions can change Advanced Airbag per­
formance and increase the risk of serious personal injury in a crash.
- Never install suspension components
that do not have the same performance
Airbag system 157
characteristics as the components origi­
nally 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 con ­
trol module and prevent the Advanced Air­ bag System from working properly.
-Always make sure that nothing can inter-
fere with the safety belt buckles and that
they are not obstructed.
Knee airbags
Description of knee airbags
Applies to vehicles: wit h knee airbags
The knee airbag system can provide supple­
mental protection to properly restrained

Q fig . 144, the knee airbag for the passenger
is at about the same height in the instrument
panel underneath the glove compartment .
The knee airbag offers additional protection
to the driver's and passenger's knees and up­
per and lower thigh areas and supplements
the protection provided by the safety belts.
If the front airbags deploy, the knee airbags

Side airbags
Description of side airbags
The airbag system can provide supplemental
protection to properly restrained occupants .
Fig. 146 Side a irbag locat ion in the d river 's seat
The s ide airbags are located in the sides of the
front sea t backrests
~ fig. 146. They are iden­
tified by the word "AIRBAG" .
The s ide a irbag system basicall y con sists o f:
- the electronic control module and external
side impact sensors
- the two side airbags located in the sides of
the front backrests
- the airbag warning light in the instrument
cluster.
The airbag system is monitored electronically
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 diagnostics) .
The s ide airbag system supplements the safe­
ty belts and can help to reduce the risk of in­
jury to the driver's and front passenger's up­
per torso on the side of the vehicle that is
struck in a side col lision . The airbag deploys
on ly in side impacts and on ly when the veh icle
acceleration registered by the control unit is h igh eno ugh . If this rate is below the refer­
ence value programmed into the control un it,
the side airbags will not be triggered,
even
though the car may be badly damaged as a re ­
sult of the collision. It is not possible to de ­
fine an airbag trigger ing range that will
cover
every
possible angle of impact, since the cir­
cumstances w ill
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 .
Q page 161, Important
safety instructions on the side airbag system .
Aside from their normal safety function, safe­
ty belts work to help keep the driver or front
passenger in position in the event of a side
collision 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 overa ll oc­
cupant restraint system in your vehicle . Al­
ways remember that the side airbag system
can only help to protect you if you are wea ring
your safety belt and wearing it properly . This
is anothe r reason why you should always wear
yo ur safety be lts, not j ust because the law re­
quires you to do so~
page 134, General
notes .
It is important to remembe r that w hile the
s u pplementa l side airbag system is designed
to reduce the likelihood of serious injuries,
other injuries, for example, swelling, bruising ,
and minor abrasions can also be associated
with deployed side airbags. Remember too,
s ide airbags will deploy only once and only in
certain kinds of accidents -your safety belts
are always there to offer protection .
Vehicle damage, repair costs or even the lack
of vehicle damage are not necessarily an indi­
cation of over-sensitive or failed airbag activa­
t ion . In some coll is ions, both front and side
airbags may inflate . Remember too, that air­
bags will deploy only once and only in ce rtain
ki nds of collisions -your safety belts a re a l­
ways there to offer protection in those acc i­
dents in which airbags are not supposed to
deploy or when they have a lready deployed.
Th e side airbag system will not deploy:
-when the ignit ion is turned off
- in side collisions when the acceleration measured by the sensor is too low
- in front -end collisions
- in rear-end collisions

162 Airbag system
-Never insta ll seat covers or replace­
ment upho lstery over the front
seatbacks that have not been specifi­
cally approved by Audi.
- Never use add itional seat cushions that
cover the areas where the side airbags
deploy.
- Damage to the original seat covers or
to the seam in the area of the side air­
bag module must always be repa ired
immed iately by an authorized Audi
dealer.
- Objects between you and the airbag can
increase the risk of injury in an acc ident
by interfering with the way the airbag
unfolds or by being pushed into you as
the airbag inflates.
- Never place or attac h accessories or
other objects (such as cupholders, tele­
phone b rackets, or even large, bulky
objects) on the doors, over o r near the
a rea marked "AIRBAG" on the seat
backrests.
- Such objects and accessories can be­
come dangerous p rojectiles and cause
i n ju ry when t he supplemental s ide air­
bag deploys.
- N ever ca rry any objects or pets in the
deployment space between them and
the airbags or a llow children or other
passengers to travel in th is posit ion .
- Always use the built-in coat hooks only
for lightwe igh t clothing. Never leave any
heavy or sharp -edged objects in the
pockets that may interfere with side air­
bag dep loyment and can cause personal
injury in an accident.
- Always prevent the side a irbags from be­
ing damaged by heavy objects knocking
against or hitting the sides of the seat­
backs.
- The airbag system can only be triggered
once.
If the a irbag has been triggered,
the system m ust be replaced by an au­
thorized Aud i deale rship.
- Damage (c rac ks, deep scratches etc.) to
the original seat covers or to the seam in
the area of the side airbag module must always be repa
ired immediately by an au­
thorized Audi dealer.
- If children are seated improperly, their
risk of injury increases in the case of an
accident
c:> page 166, Child Safety.
- Never attempt to modify any compo­
nents of the airbag system in any way.
- In a side collision, side airbags will not
function properly if sensors cannot cor­
