for the adaptation has expired or the pro­
gram ming was unsuccessful. Repeat the
programming from step 3 on the controls
or se lect another distance from the radia­
tor grille.
9. If the garage door or other devices still
fail to be activated w ith the Homelink
control buttons after programming is
completed, it is possible that these sys­
tems might be working with a rolling code
instead of the normal fixed code.
A Roll­
ing code programming must be per­
formed

Program the remaining two buttons acc ord ing
to the instructions mentioned above . Begin
similarly with the 3rd step if the program­
ming connection was successful for the first
button.
Remote control units for garage door openers
in Canada are set to stop transmitting radio
frequency signa ls after two seconds. This time
may not be suffic ient for the Homelink sys­
tem to learn the radio frequency signal. Per­
form all other steps as described above.
Erasing the buttons
.,. Switch on the ignition (do not start the en­
gine).
.,. Press and hold both of the outer buttons un­
til the LED@ turns off completely (about

A WARNING
Drivers who are unbelted, out of position
or too close to the airbag can be ser iously
injured by an airbag as it unfolds. To help
reduce the risk of serious personal injury :
- Always adjust the dr iver's seat and the
steering wheel so that there are at least
10 inches (25 cm) between your breast­
bone and the steering wheel.
- Always hold the steering wheel o n the
outside of the steering wheel rim with
your hands at the 9 o'clock and 3 o'clock posit ions to he lp red uce the risk of pe r­
sonal in jury if the drive r's airbag inflates.
- Never hold the steer ing whee l at the
1 2 o'clock posit ion or w it h your hands at
other pos it ions inside the steering wheel
rim or on the stee ring wheel h ub. Hold­
ing the steering wheel the wrong way
can cause serious injuries to the hands,
arms and head i f the driver 's airbag de­
ploys.
- Pointing the steering whee l toward your
face decreases the ab ility o f the supp le­
menta l dr iver's airbag to protect you in a
co llision.
- Always s it in an upright position and nev­
er lean against or place any part of your
body too close to the a rea where the air­
bags are located.
- Before driv ing, a lways ad just the front
seats and head restra ints prope rly and
make s ure that all passengers are prop­
er ly restrained.
- Never adjust the seats while the vehicle
is moving . Your seat may move unexpect­
edly and you could lose control of the ve­
hicle.
- Never drive with the backrest recl ined o r

Proper seating position for the front
passenger
The proper front passenger seating position
is important for safe, relaxed driving.
For your own safety and to reduce the risk of
injury in the event of an accident, we recom ­
mend that you adjust the seat for the front
passenger to the following position:
~ Move the front passenger seat back as far as
possible . There must be a m inimum of
1 0 i nches (25 cm) between the breastbone
and the ins trument panel
c:;, &, .
~ Adjust t he a ngle of the seatbac k so that it is
in an upr igh t position and yo ur ba ck comes
in full contact wit h it whenever the vehicle is
moving.
~ Applies to vehicles with adjustab le head re­
straints: Adjust the head restraint so the up­
per edge is as even as possible wit h the top
of your head. If that is not possib le, try to
adjust the head restraint so that it is as
close to this pos it ion as poss ible.
~ Keep both feet flat on the floor in front of
t he fron t passenger seat .

Safety belt preten-
• s1oners
How safety belt pretensioners work
In front, side and rear-end collisions above a
particular severity, safety belts are tensioned
automatically.
The safety belts are equipped with safety belt
pretensioners. The system is activated by sen­
sors in front, s ide and rear-end collisions of
great severity. This tightens the belt and takes
up belt slack
Q .&. in Service and disposal of
safety belt pretensioner on page 139.
Taking
up the slack he lps to reduce fo rward occupant
movement during a collision .
(D Note
Never let the belt remain over a rear seat­
back that has been fo lded forward.

148 Airbag system
-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
driver seat from the vehicle .
- 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-sensing mat and send the
wrong information to the airbag control
unit.
- Never store items under the front pas·
senger seat. Parts of the Advanced Air­
bag System under the passenger seat
could be damaged, preventing them and
the airbag system from working proper­
ly.
- Never place seat covers or replacement
upholstery that have not been specifical­
ly approved by Audi on the front seats.
- Seat covers can prevent the Advanced Airbag System from recognizing child re­
straints or occupants on the front pas­
senger seat and prevent the side airbag in the seat backrest from deploying prop­
erly.
- Never use cushions, pillows, blankets or
similar items on the front passenger
seat. The additional padding will prevent
the weight-sensing mat in the seat from
accurately registering the child restraint
or person on the seat and prevent the
Advanced Airbag System from function­
ing properly.
- If you must use a child restraint on the
front passenger seat and the child re- straint manufacturer's instructions
re­
quire the use of a towel, foam cushion or
something else to properly position the
child restraint, make certain that the
PASSENGER AIR BAG OFF light comes
on and stays on whenever the child re·
straint is installed on the front passen­
ger seat.
- If the PASSENGER AIR BAG OFF light
does not come on and stay on, immedi­
ately install child restraint in a rear seat­
ing position and have the airbag system
inspected by your authorized Audi dealer.
How the Advanced Airbag System
components work together
The front Advanced Airbag System and the
side airbags supplement the protection of­
fered by the front three-point safety belts
with pretensioners and load limiters and the
adjustable head restraints to help reduce the
risk of injury in a wide range of accident and
crash situations. Be sure to read the impor­
tant information about safety and heed the
WARNINGS in this chapter.
Deployment of the Adv a need Airbag System
and the activation of the safety belt preten­
sioners depend on the deceleration measured
by the crash sensors and registered by the
electronic control unit. Crash severity depends
on speed and deceleration as well as the mass
and stiffness of the vehicle or object involved
in the crash .
On the passenger side, regardless of safety
belt use, the airbag will be turned off if the
weight on the passenger seat is less than the
amount programmed in the electronic control
unit. The front airbag on the passenger side
will also be turned off if one of the child safe­
ty seats that has been certified under Federal
Motor Vehicle Safety Standard 208 has been
recognized on the seat. The
PASSENGER AIR
BAG OFF
light comes on and stays on to tell
you when the front Advanced Airbag on the passenger side has been turned off

Activating the convertible locking retractor
Use the convertible locking retractor to se­
cure a child restraint .
Always heed the child safety seat manufactur­
er's instructions when installing a child re­
straint in your vehicle. To activate the conver­
tible locking retractor :
"" Place the child restraint on a seat, prefera­
bly on the rear seat.
.. Slowly pull the belt
all the way out.
.. Route it around or through the child re­
straint belt path¢.&_ .
.. Push the child safety seat down with your
full weight to get the safety belt really tight.
.. Insert the belt tongue into the buckle for
that seating position .
.. Guide the sa fety belt back into the retractor
until the belt lies flat and snug on the child
safety seat .
.. You should hear a "clicking " noise as the
belt winds back into the inertia reel. Test the
convertible locking retractor by pulling on
the belt. You should no longer be able to
pull the belt out of the retractor. The con­
v ertible locking retractor is now activated.
.. Make sure that the red release button is fac­
ing away from the child restraint so that it
can be unbuckled quickly .
""Pull on the belt to make sure the safety belt
is properly tight and fastened so that the
seat cannot move forward or sideways more
than one inch (2.5 cm).
A WARNING
Using the wrong child restraint or an im­
properly installed child restraint can cause
serious personal injury or death in a crash.
- Always make sure that the safety belt re-
tractor is locked when installing a child safety seat. An unlocked safety belt re­
tractor cannot hold the child safety seat in place during normal driving or in a
crash .
- Always buckle the child safety seat firmly
in place even if a child is not sitting in it.
-
Child Safety 173
A loose child safety seat can fly around
during a sudden stop or in a crash.
- Always make sure the seat backrest to
which the child restraint is installed is in
an upright position and securely latched
into place and cannot fold forward . Oth­
erwise, the seatback with the child safety
seat attached to it could fly forward in
the event of an accident or other emer­
gency situation.
- Always read and heed all WARNINGS
whenever using a child restrained in ave­
hicle is being used¢
page 161. Special
precautions apply when installing a child
safety seat on the front passenger seat
¢ page 141, Child restraints on the front
seat -some important things to know .
Deactivating the convertible locking
retractor
T he convertible locking retractor for child re­
straints will be deactivated automatically
when the bel t is wound oil the way bock in to
the retractor .
.. Press the red button on the safety belt buck­
le . The belt tongue will pop out of the buck­
le.
.,. Guide the safety belt all the way back into
its stowed position .
Always let the sa fety belt retract completely
into its stowed position . The safety belt can
now be used as an ordinary safety belt with­
out the convertible locking retractor for child
restraints.
If the convertible locking retractor should be
activated inadvertently, the safety belt must be unfastened and guided completely back in­
to its stowed position to deactivate this fea­
ture. If the convertible locking retractor is not
deactivated , the safety belt will gradually be-
come tighter and uncomfortable to wear.

Intelligent technology Notice about data
recorded by vehicle
control modules
Your vehicle is not equipped with an Event Da­
ta Recorder (EDR), installed by some manu­
facturers for 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 retr ieval 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 examp le, engine function, emis­
sion control, as well as for the airbags and
safety belts.
These electronic control modules also record
vehicle-related data during norma l 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 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 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
Control (ESC)
Description
ESC helps to improve road holding and vehicle
dynamics to help reduce the probability of
skidding and loss of veh icle control. It works
only when the engine is running. ESC detects
Intelligent technology 179
certain difficult driving situations, including
when the vehicle is beginning to spin (yaw)
out of control and helps you to get the veh icle
back under control by se lectively braking the
wheels, and/or reducing engine power and
providing steering ass istance to help hold the
vehicle on the driver's intended course. The in­
dicator light
B.J in the instrument cluster
blinks when ESC is taking action to help you
control the vehicle.
ESC has limitations .
It is important to remem­
ber that ESC cannot overcome the laws of
physics.
It will not always be able to help out
under all conditions you may come up against.
For example, ESC may not always be able to
help you master situations where there is a
sudden change in the coefficient of friction of
the road surface. When there is a section of dry road that is suddenly covered with water,
slush or snow, ESC cannot perform the same
way it would on the dry surface . If the vehicle
hydroplanes (rides on a cushion of water in­
stead of the road surface), ESC will not be
able to help you steer the vehicle because con­
tact with the pavement has been interrupted
and the vehicle cannot be braked or steered .
During fast cornering, particularly on winding
roads, ESC cannot always deal as effectively
with difficu lt driving situations than at lower
speeds. When towing a trailer, ESC is not able
to help you regain control as it would if you
were not tow ing a trailer.
Always adjust your speed and driving style to road, traffic and weather conditions. ESC can­
not override the vehicle's physical limits, in­
crease the available traction, or keep a vehicle
on the road if road departure is a result of
driver inattention. Instead, ESC improves the
possibility of keeping the vehicle under con­
trol and on the road dur ing extreme maneu­
vers by using the driver's steering inputs to
help keep the vehicle going in the intended di­
rection. If you are traveling at a speed that
causes you to run off the road before ESC can
provide any assistance, you may not experi­
ence the benefits of ESC.

Catalytic converter
It is very important that your emission con­
trol system (catalytic conv ert er) is function ­
ing properly to ensure that your vehicle is run­
ning in on env ironm entally sound manner.
,,. Always use lead-free gaso line Q page 201,
Fuel supply .
,,. Never run the tank down a ll th e way to emp ­
ty.
,,. Never put too much moto r oil in your engine
Q page 211 , ~ Adding engine oil .
,,. Never try to push -or tow -start your ve hicle .
T he cata lytic converter is an eff ic ient "clean­
up" device built in to the exhaust system of
the vehicle . The catalytic converter burns
many of the polluta nts in the exhaust gas be ­
fore they are released into the atmosphe re . The exclus
ive use of unleaded f uel is critica lly
important for the life of the catalytic conv ert­
er and p roper funct ion ing of the eng ine .
A WARNING
=
-The temperature of the exhaust system
is high, both when driving and after stop­
p ing the eng ine .
- Never touch the exhaust tail pipes once
they have become hot. This could result
in burns.
- Do not park or operate the vehicle i n
areas where the hot exhaust system may
come in co ntact with dry grass, brush,
fue l spill or other material wh ich can
cause a fire .
- Do not app ly additional undercoating or
r u stp roofing on or nea r the exhaust
manifold, exhaust pipes, cataly tic con­
ver ter or he at s hields. Dur ing driv ing, the
substance used fo r undercoating could
overheat and cause a fire.
CI) Note
- Be aware tha t just o ne tank filling with
leaded fu el w ill alre ady ser io usly de ­

the exhaust system and th is co uld cause
the catalytic converter to overheat.
- Do not turn off the ignition while the ve­
hicle is mov ing.
- Do not contin ue to ope rate your veh icle
under these conditions, as otherwise fuel
can reach the catalyt ic converter. Th is

192 Trailer towing
Trailer towing Driving with a trailer
General information
Your Audi was designed primarily for passen­
ger transportation .
If you plan to tow a trai ler, p lease remember
that the additional load will affect durability,
economy and performance .
Trailer towing not on ly places more stress on
the vehicle, it also calls for more concentra­
tion from the driver.

gross trailer weight. The hitch must be suita­
ble for your vehicle and trailer and must be
mounted securely on the veh icle's chassis at a
technically sound location. Use only a trailer
hitch with a removable ball mount. Always
check with the trailer hitch manufacturer to
make sure that you are using the correct
hitch.
Do not use a bumper hitch.
The hitch must be installed in such a way that
it does not interfere with the impact-absorb­
ing bumper system . No modifications should
be made to the vehicle exhaust and brake sys­
tems . From time to time, check that all hitch
mounting bolts remain securely fastened.
When you are not towing a trailer, remove the
trailer hitch ball mount. This prevents the
hitch from causing damage should your vehi­
cle be struck from behind
