First, adjust the driver's seat correctly.
• Push the lever
c:> fig . 101 down as far as it
will go
c:> & .
• Move the steer ing whee l to the desired po-
s it ion.
• Push the lever back up as far as it will go.
There must be at least 10 inches (25 cm) be­ tween your chest and the center of the steer­
i ng wheel. If you cannot si t more than 10 in­
ches (25 cm) from the steering whee l, see if
adaptive equipment is available to help you
reach the pedals and increase the distance
from the steering whee l.
F or detai led information on how to adjust the
driver's seat, see
c:> page 63, Power seat ad­
justment.
The stee ring wheel can be adjusted even when
the ignition is turned off.
8_ WARNING
Improper use of steering wheel adjust­
ment and improper seating position can
cause serious personal injury .
- Adjust the steering whee l co lumn on ly
when the vehicle is not moving to pre­
vent loss of veh icle control.
- Always make sure that the ad justment
lever is securely pushed up so that the
-
position of the steering wheel cannot be
changed unintentionally when the vehi­
cle is mov ing.
- Adj ust the driver's seat or steering whee l
so that there is a minimum of 10 inches
(25 cm) between your breastbone and
the steering wheel
c:> page 104,
fig. 117.
If you cannot maintain this
minim um distance, the airbag system
cannot protect you properly.
- If physical limitations prevent you from sitt ing 10 inches (25 cm) or more from
the steering wheel, check wit h your au­
thorized A udi dealer to see if adaptive
equipment is available .
- Pointing the steering wheel toward your
face decreases the ability of the s upple­
mental driver's airbag to protect you in
an accident. Always make sure that the
steer ing whee l is po inted towards your
chest.
- Always hold the steering wheel on the
outside of the steering wheel rim with
your hands at the 9 o'clock and 3 o'clock
positions to help reduce the risk of per­
sonal injury if the driver's a irbag inflates .
- Never hold the steering wheel at the
12 o'clock position or with your hands at
other positions inside the steer ing wheel
rim or on the steering wheel hub. Ho ld­
ing the steering whee l the wrong way
can cause se rious inj uries to the hands,
arms and head if the driver's airbag in ­
f lates .

airbag system and prevent that system from
working properly in a collision.
There are some important things you have to know to make sure that the effectiveness of
the system will not be impaired and that dis­
carded components do not cause injury or pol­
lute the environment.
.&_ WARNING
Improper care, servicing and repair proce­
dures can increase the risk of personal in­
jury and death by preventing an airbag
from deploying when needed or deploying an airbag unexpectedly:
- Never cover, obstruct, or change the steering wheel horn pad or airbag cover
or the instrument panel or modify them
in any way.
- Never attach any objects such as cup
holders or telephone mountings to the
surfaces covering the airbag units.
- For cleaning the horn pad or instrument
panel, use only a soft, dry cloth or one
moi5tened with plain water. Solvent5 or
cleaners could damage the airbag cover
or change the stiffness or strength of the
material so that the airbag cannot de­
ploy and protect properly.
- Never repair, adjust, or change any parts
of the airbag system .
- All work on the steering wheel, instru­
ment panel, front seats or electrical sys­
tem (including the installation of audio
equipment, cellular telephones and CB
radios, etc .) must be performed by a
qualified technician who has the training
and special equipment necessary.
- For any work on the airbag system, we
strongly recommend that you see your authorized Audi dealer or qualified work­
shop.
- Never modify the front bumper or parts
of the vehicle body .
-Always make sure that the side airbag
can inflate without interference:
- Never install seat covers or replace­
ment upholstery over the front seat- backs that have not been specifically
approved by Audi.
- Never use additional seat cushions that
cover the areas where the side airbags
inflate.
- Damage to the original seat covers or
to the seam in the area of the side air­
bag module must always be repaired
immediately by an authorized Audi
dealer .
- The airbag system can be activated only
once . After an airbag has inflated, it
must be replaced by an authorized Audi
dealer or qualified technician who has
the technical information, training and
special equipment necessary.
- The airbag system can be deployed only
once. After an airbag has been deployed,
it must be replaced with new replace­
ment parts designed and approved espe­
cially for your Audi model version. Re­
placement of complete airbag systems
or airbag components must be per­
formed by qualified workshops only. Make sure that any airbag service action
is entered in your Audi Warranty
& Main­
tenance booklet under
AIRBAG REPLACE­
MENT RECORD .
@ For the sake of the environment
Undeployed airbag modules and preten­
sioners might be classified as Perchlorate
Material - special handling may apply, see
www .dtsc .ca.gov/hazardouswaste/per­
chlorate. When the vehicle or parts of the restraint system including airbag modules
and safety belts with pretensioners are
scrapped, all applicable laws and regula­
tions must be observed. Your authorized
Audi dealer is familiar with these require­ ments and we recommend that you have
your dealer perform this service for you.

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
Program (ESP)
Description
ESP 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. ESP detects
Intelligent technology 161
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
G] in the instrument cluster
blinks when ESP is taking action to help you
control the vehicle.
ESP has limitations. It is important to remem­
ber that ESP 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, ESP 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, ESP 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), ESP 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, ESP cannot always deal as effectively
with difficult driving situations as at lower
speeds. When towing a trailer, ESP is not able
to help you regain control as it would if you
were not tow ing a trailer.
A lways adjust your speed and driving style to
road, traffic; and weather conditions. ESP 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, ESP improves the
poss ibility 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 ESP can
provide any assistance, you may not experi­
ence the benefits of ESP .
