General information
Applies to vehicles: with Home link® universal remote
control
The Homelink ® feature can learn up to three
radio frequency codes for most current trans­
mitters used for operating garage doors, es­ tate gates, home or outdoor lighting sys­
tems, and other devices.
You must first program the Homelink ® trans­
mitter before you can use the system
~ page 141, Programming the Homelink ®
transmitter.
In order to program the Home link ® transmit­
ter for dev ices utilizing rolling code, a second
pe rson on a ladder who ca n safe ly reach the
garage door opener motor is recommended. I t is also necessary to locate the "learn" but­
ton on your garage door opener motor . Refer
to the operating instructions for the opener,
as the location and color of this button may
vary by manufacturer.
You can still use the origina l remote contro l
for the device at any time .
.&_ WARNING
-
- Never use the Homelink ® transmitte r
with any garage door opener that does
have not the safety stop and reverse fea­
tu re as requ ired by federa l safety stand­
ards. Th is includes any garage door open­
er mode l manufact ured before April 1,
1982.
- A garage door op ener which cannot de­
te ct an object, signa ling the doo r to stop
and reverse does no t mee t current feder ­

area because the rear lid cannot be fully
closed.
-If you absolutely must drive with the rear
lid open, observe the following notes to
reduce the risk of poisoning:
- Close all windows,
- Close the panoramic tilting sunroof*,
- Open all air outlets in the instrument
panel,
- Switch off the air recirculation,
- Set the fresh air fan to the highest
speed.
A WARNING
Always make sure that the doors, all win­
dows, the panoramic tilting sunroof* and
the rear lid are securely closed and locked
to reduce the risk of injury when the vehi­
cle is not being used.
-After closing the rear lid, always make sure that it is properly closed and locked.
- Never leave your vehicle unattended es­
pecially with the rear lid left open. A
child could crawl into the vehicle through
the luggage compartment and close the
rear lid becoming trapped and unable to
get out. Being trapped in a vehicle can
lead to serious personal injury.
- Never let children play in or around the
vehicle.
- Never let passengers ride in the luggage
compartment. Vehicle occupants must
always be properly restrained in one of
the vehicle's seating positions.
(D Tips
- Air circulation helps to reduce window
fogging. Stale air escapes to the outside
through vents in the trim panel. Be sure
to keep these slots free and open.
- The tire pressure must correspond to the load. The tire pressure is shown on the
tire pressure label. On USA vehicles, the
tire pressure label is located on the driv­
er's side B-pillar. On Canada vehicles, the
tire pressure label is located either on
the driver's side B-pillar or inside the fuel

the recommended cold tire inflation
pressures for the vehicle at its maximum
capacity weight and the tires that were
on your vehicle at the time it was manu­
factured . For recommended tire pres­
sures for normal load conditions, please

Tie-downs
The luggage compartment is equipped with
four tie-downs to secure luggage and other
items.
Use the tie -downs to secure your cargo prop­
erly ~
page 150, Loading the luggage com­
partment .
In a collision, the laws of physics mean that
even smaller items that are loose in the vehi­
cle will become heavy missiles that can cause
serious injury. Items in the vehicle possess en­
ergy which vary with vehicle speed and the
weight of the item. Vehicle speed is the most
significant factor.
For example, in a frontal collision at a speed
of 30 mph (48 km/h), the forces acting on a
10-lb (4.S kg) object are about 20 times the
normal weight of the item. This means that
the weight of the item would suddenly be
about 200 lbs. (90 kg). You can imagine the
injuries that a 200 lbs. (90 kg) item flying
freely through the passenger compartment
could cause in a collision like this.
A WARNING
Weak, damaged or improper straps used
to secure items to tie-downs can fail dur­
ing hard braking or in a collision and cause
serious personal injury.
- Always use suitable mounting straps and
properly secure items to the tie-downs in
the luggage compartment to help pre­
vent items from shifting or flying for­
ward as dangerous missiles.
- When the rear seat backrest is folded
down, always use suitable mounting
straps and properly secure items to the

Why safety belts?
Frontal collisions and the law of physics
Frontal crashes create very strong forces for
people riding in vehicles .
Fig. 166 U nbe lted occupa nts in a ve hicle hea ding for a
wall
F ig. 167 T he ve hicle c ras hes into t he wall
The physical principles are simp le. Both the
ve hicle and the passengers possess energy
which varies w ith vehicle speed and body
weight . Enginee rs call this energy "kinetic en ­
e rgy ."
The higher the speed of the vehicle and the greater the vehicle 's weight, the more energy
that has to be "absorbed" i n the crash .
Vehicle speed is the most sign ificant factor . If
the speed doubles from 15 to 30 mph (25 to
50 km/h) , the energy inc reases 4 t imes !
Because t he passengers of t his ve hicle are not
using safety belts

moving at the same speed the vehicle was
mov ing just before the crash, unt il something
stops them -here, the wall

The same pr inc iples apply to peop le sitting in
a vehicle that is involved in a frontal co llision .
Even at city speeds of 20 to 30 mph (30 to 50
km/h), the forces act ing on the body can
Safety belts 155
reach one ton (2,000 lbs . or 1,000 kg) or
more . At greater speeds, these forces are
even
higher .
People who do not use sa fe ty belts are also
not attached to their vehicle. In a frontal coll i­
sio n they wi ll also keep moving forward at the
speed their veh icle was t ravell ing just before
the crash. Of co urse, the laws of physics don't
just app ly to frontal collisions, they determine
what happens in all kinds of acc idents and col ­
lis ions .
What happens to occupants not wearing
safety belts?
In crashes unbelt ed o ccupants cannot stop
themselves from flying forward and being in­
jured or killed. Always wear your safety belts!

with the vehicle interior has all the energy
they had just before the crash. Never rely on airbags alone for protection.
Even when they deploy, airbags provide only
additional protection. Airbags are not sup­
posed to deploy in all kinds of accidents. Al­
though your Audi is equipped with airbags, all
vehicle occupants, including the driver, must
wear safety belts correctly in order to mini­ mize the risk of severe injury or death in a
crash.
Remember too, that airbags will deploy only
once and that your safety belts are always
there to offer protection in those accidents in
which airbags are not supposed to deploy or when they have already deployed . Unbelted
occupants can also be thrown out of the vehi­
cle where even more severe or fatal injuries
can occur.
It is also important for the rear passengers to
wear safety belts correctly. Unbelted passen­
gers in the rear seats endanger not only them­
selves but also the driver and other passen­
gers <=>
fig. 169. In a frontal collision they will
be thrown forward violently, where they can
hit and injure the driver and/or front seat pas­
senger.
Safety belts protect
People think it's possible to use the hands to
brace the body in a minor collision. It's simply
not true!
Fig. 170 Drive r is co rrect ly res trained in a sudden brak­
ing maneuve r
Safety belts used properly can make a big dif­
ference . Safety belts help to keep passengers
in their seats , gradually reduce energy levels applied to
the body in an accident, and help
prevent the uncontrolled movement that can
cause serious injuries. In addition, safety belts
reduce the danger of being thrown out of the
vehicle .
Safety belts attach passengers to the car and give them the benefit of being slowed down
more gently or "softly" through the "give" in
the safety belts, crush zones and other safety
features engineered into today's vehicles. By
"absorbing" the kinetic energy over a longer
period of time, the safety belts make the
forces on the body more "tolerable" and less
likely to cause injury.
Although these examples are based on a fron­
tal collision, safety belts can also substantial­ ly reduce the risk of injury in other kinds of
crashes. So, whether you're on a long trip or
just going to the corner store, always buckle
up and make sure others do, too. Accident sta­
tistics show that veh icle occupants properly
wearing safety belts have a lower risk of being
injured and a much better chance of surviving
an accident. Properly using safety belts also
greatly increases the ability of the supplemen ­
tal airbags to do their job in a collision. For
this reason, wearing a safety belt is legally re­
quired in most countries including much of
the United States and Canada .
Although your Audi is equipped with airbags,
you still have to wear the safety belts provid­
ed . Front airbags, for example , are activated
only in some frontal collisions. The front air­
bags are not activated in all frontal collisions,
in side and rear collisions, in roll overs or in
cases where there is not enough deceleration
through impact to the front of the vehicle.
The same goes for the other airbag systems in
your Audi. So, always wear your safety belt and make sure everybody in your vehicle is
properly restrained!

Front airbags
Description of front airbags
The airbag system can provide supplemental
protection to properly restrained front seat
occupants.
F ig . 175 Location of driver airbag: in steer ing whee l
Fig. 176 Location of front passenger's airbag: in the in ­
strument panel
Your veh icle is equipped with an "Advanced
A irbag System" in compliance with United
States Federal Motor Vehicle Safety Standard ( FM VSS) 208 as app licab le at the time your
ve hicl e was manufac tured. The system senses
the position of the front seats and controls
front airbag inflation with a valve, depending
on the distance between the respect ive seat
and the steering wheel or instrument panel.
The safety belts for the seats have "preten­
sioners" that he lp to take slack out of the belt
system . The pretensioners a re also activated
by the electron ic cont ro l unit for the ai rbag
system. T
he front safety belts also have load limiters
to help reduce the forces applied to the body
i n a crash .
T he airbag for the drive r is in the stee ring
whee l hub¢
fig. 175 and the airbag for the
front passenger is in the instrument panel
~ fig. 176. The general locat ion of the a irbags
is marked "AIRBAG".
T here is a lot you need to know about the ai r­
bags in your vehicle. We urge you to read the
detailed information about airbags, safety
belts and child safety in this and the other
chapters that make up th e owner's literature.
P lease be sure to heed the WARNINGS -they
are extremely importa nt for your safety and
the safety of your passengers, especially in­
fants and small chi ldren.
_&. WARNING
Neve r rely on airbags alone for p rotection.
- Even w hen they deploy, airbags provide
only s upplement al pro te ctio n.
- Airbag work most effect ive ly when used
with p roperly wor n safety bel ts.
- Therefore, always wea r you r safety belts
a nd make sure tha t eve rybody in your ve­
h icle is properly res trained.
_&. WARNING
A pe rson on the front passenger seat, es­
pe cial ly infa nts and sm all ch ildren, w ill re­
ceive serio us inju ries and can even be kil­
l ed by being too close to the airbag when
it inflates .
- Although t he Advanced Airbag System in
your veh icle is designed to tur n off the
front passenger airbag if an infant or a
small child is on the front passe nger
seat, nobody can absolutely guarantee
that deployment under these special
conditions is imposs ible in all conceiva­
b le sit uat ions that may happen dur ing
the useful life of your vehicle.
- The Advanced Airbag System can dep loy

168 Airbag sys tem
For exa mple , the ai rb ag ma y depl oy if:
-a small child that is heavier than a typical 1
year-o ld child is on the front passenger seat
(regardless of whe ther the child is in one of
the chi ld safety seats listed
¢ page 188),
-a ch ild who has outg rown child rest raints is
on the front passenger seat.
If the front passenger airbag is turned off, the
PA SSENGER AIR BAG OFF light in the cente r
of the instrument panel w ill come on and stay
on.
The front a irbag on the passenger side may
not deploy (the PAS SENGER AIR BAG OFF
light does not ill uminate and stay lit) if:
- a small adult or teenager is on the front pas­
senger seat
- a passenger who is not sitt ing upright wit h
their back against a non-reclined backrest
with their feet on the veh icle floo r in front
of the seat is on the front passenger seat.
If the front passenge r airbag deploys, the
Federal Standard requires the airbag to meet
the "low risk" deployment criteria to help re­
d uce the risk of inj ury through interaction
with the airbag. " Low risk" deployment occurs
in those crashes that take place at lower de­
celerations as defined in the e lectronic control
un it.

Alw ays remember : Even though you r vehicle
is equipped with Advanced Airbags, the safest
p lace for children is properly restrained on the
back seat . Please be sure to read the impor­
tant information in the sect ions that follow
and be sure to heed a ll of the WARNINGS.
A WARNING
To reduce the risk of injury when an airbag
inf lates, always wear safety belts properly.
- If you are unrestrained, lean ing forward,
sitting sideways or out of position in any
way, your risk of in jury is much higher.
- You w ill also receive serious injuries and
cou ld even be killed if you are up against
the a irbag or too close to it when it in- f
lates - even with an Advanced A irbag
¢page 162.
A WARNING
-A child in a rearward-fac ing ch ild safety
seat installed on the front passenger seat
will be serious ly injured and can be killed if
the front airbag inflates - even with an Ad­
vanced A irbag System .
- Although the Advanced Airbag System in your veh icle is designed to turn off the
front airbag when a rearward-facing child restraint has been instal led on the
front passenger seat, nobody can abso­
lutely g uarantee that dep loyment is im ­
possible in all conceivable situations that
may happen during the usefu l life of your
veh icle.
- The inflating airbag will hit the c hild
safety seat or infant carrier with great
force and will smash the child safety seat
and child aga inst the backrest, center
armrest, door, or roof.
-Always install rearward -facing ch ild re ­
straints in the back seat.
- If you must install a rearward fac ing
child safety seat on the front passenger
seat because of exceptiona l circumstan­
ces and the
PASSENGER AIR BAG OFF
light does not come on and stay on, im­
mediately insta ll th e rear-fac ing c hild
safety sea t in a rear seating position and
have the airbag system inspected by your
authorized Audi dealer .
A WARNING
If, in exceptional circumstances, you m ust
insta ll a forward -facing child restraint on
the front passenger's seat:
- Always make sure the forward-facing
seat has been designed and certified by
its manufacturer for use on a front seat
with a passenger front and s ide a irbag.
- Never p ut the forward-facing child re­
straint up against or very near the instru-
ment panel.

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 177
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

Notice about data
recorded by vehicle
control modules
Your veh icle is not equipped with an Event Da­
ta Recorder (EDR), installed by some manu­
facturers fo r the express purpose of capturing
data for retrieval after an accident or crash
event. EDR's are sometimes called "crash re­
corders".
Some state laws restrict the retrieval or down­
loading of data stored by EDR's that were in­
stalled 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 with a number of electron­
ic control modules for various vehicle systems
such as, for example, engine function, emis­
sion control, as well as for the airbags and
safety belts .
These electronic control modules also record
vehicle-related data during normal vehicle op­
eration for diagnostic and repair purposes .
The recording capacity of the electronic con­
trol modules is limited to data (no sound is re ­
corded) and only a small amount of data is ac­
tually recorded over a very limited pe riod 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 we ll as restraint
system use and performance in the event of a
crash or other condition. Stored data can only be read and downloaded with special equip­
ment .
Electronic stabilization
Program (ESP)
General information
The ESP improves the vehicle stability .
Fig. 195 f;. OFF button
Fig. 196 Center console wit h ~ OFF button
ESP is designed to help you maintain vehicle
control in situations where the car approaches
the limits of "grip", especia lly when accelerat­
ing and cornering . ESP reduces the risk of
skidding and improves stability under all road
conditions .
The system operates across the ent ire 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 Regu­
lation System (ASR) are integrated in the elec­
tronic stabilization program. In addition to
the data provided by these functions, the ESP
control unit requires additional measurement
data provided by high performance sensors.
