Steering
Adjustable steering wheel
The height and reach of the steering wheel
can be adjusted .
Fig. 101 Lever under the steering column
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 .

Ignition lock and ignition switch
Ignition lock
The engine can be started or turned off with
the ignition key.
Fig. 102 I gni tion lock positio ns
Ignition off@
In position ¢ fig. 102@both the ignition and
engine are off, and the steering is locked.
To
lock the steering after you have removed
the ignition key, turn the steering wheel in ei­
ther direction until you hear it lock into place.
You shou ld always lock the steering whenever
you leave your vehicle. This makes a vehicle
theft even more difficul t
q ,&.
Ignition on CD
If it is difficult to turn the key after you have
inserted it into the ignition lock, turn the
steering wheel back and forth. This will take
the load off the steering lock mechan ism and
you will be able to turn the key freely and
start the engine. On vehicles with a diesel en­
g ine*, the system can preheat in this pos ition .
Starting the engine @
In this position the engine starts. While the
engine is starting, the power supply to the
headlights and other electrical consumers is
temporarily interrupted to conserve battery power. After the engine has started, release
the key and it will return to position @.
Before the starter can be operated again the
key must be turned back to position @. The
non-repeat lock prevents you from damag ing
the starter when the engine is running.
On the road 89
A WARNING
-Never remove the key from the ignition
lock wh ile the vehicle is moving. The
steering wheel will lock caus ing loss of
control.
- If you have to leave your vehicle - even
for just a minute -always remove the ig­
nition key and take it with you. This is es­
pecia lly important if you are going to
leave children behind in the vehicle. The
children could start the engine or use
other vehicle controls. Unsupervised use
of vehicle controls (for example, power
windows) can cause serious personal in­
juries.
(D Tips
If the vehicle battery has been disconnect­
ed and then reconnected, then you must leave the key in position @for about 5
seconds before you can start the engine.
Ignition key safety lock
Applies to vehicles: wit h automatic transmission
The ignition key can only be removed when
the selector lever is in the "P" (Park) position.
Place the selector lever in the "P" position be­
fore switching off the engine .
After switching off the ign ition, the ignition
key can on ly be removed from the ignition
lock when the selector lever is in the "P"
(Park) position. After you have removed the
key, the se lector lever is locked and cannot be
moved.

~ Always keep both feet in the footwell so
that you are in control of the vehicle at all
times.
For detailed information on how to adjust the
driver's seat, see ¢
page 62, Adjusting front
seats manually
or ¢ page 63, Adjusting the
power seat .
A WARNING
Drivers who are unbelted, out of position
or too close to the airbag can be seriously
injured by an airbag as it unfolds. To help
reduce the risk of serious personal injury:
- Always adjust the driver'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 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 airbag inflates.
- Never hold the steering wheel at the
12 o'clock position or with your hands at
other positions inside the steering wheel
rim or on the steering wheel hub. Hold­
ing the steering wheel the wrong way
can cause serious injuries to the hands,
arms and head if the driver's airbag de­
ploys .
- Pointing the steering wheel toward your
face decreases the ability of the supple­ mental driver's airbag to protect you in a
collision .
- Always sit in an upright position and nev­
er lean against or place any part of your
body too close to the area where the air­
bags are located.
- Before driving, always adjust the front
seats and head restraints properly and
make sure that all passengers are prop­
erly 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.
Driving Safely 105
- Never drive with the backrest reclined or
tilted far back! The farther the backrests
are tilted back, the greater the risk of in­
jury due to incorrect positioning of the safety belt and improper seating posi­
tion .
- Children must always ride in child safety
seats ¢
page 143. Special precautions
apply when installing a child safety seat
on the front passenger seat¢
page 122.
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:
~ Adjust the angle of the seatback so that it is
in an upright position and your back comes
in full contact with it whenever the vehicle is
moving.
~ Adjust the head restraint so the upper edge
is as even as possible with the top of your
head. If that is not possible, try to adjust
the head restraint so that it is as close to
this position as possible
¢page 107.
~ Keep both feet flat on the floor in front of
the front passenger seat .
~ Fasten and wear safety belts correctly
¢page 116.
For detailed information on how to adjust the
front passenger's seat, see ¢
page 61.
A WARNING
Front seat passengers who are unbelted,
out of position or too close to the airbag
can be seriously injured or killed by the air­
bag as it unfolds. To help reduce the risk of
serious personal injury:
- Passengers must always sit in an upright
position and never lean against or place
any part of their body too close to the
area where the airbags are located.

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 .

However, do not expect that the ABS shortens
braking distance under
all circumstances.
When driving on grave l or on newly fallen
snow on top of icy surfaces, braking distance may be even longer, therefore, under these
circumstances, it is especially important that
you dr ive slowly and with great care .
How th e ABS syste m work s
An automatic check is made when a speed of
about 4 mph (6 km/h) is reached. When this
happens, a pumping noise can be heard .
If an individua l wheel begins to rotate too
slowly in relation to vehicle speed and tends
to lock, the ABS automatically reduces brake
pressure to prevent that wheel from locking.
This automatic adjustment process will cause
a
s light vib ration of the brake pedal and some
noises to alert you that vehicle speed must be
adapted to existing road and traff ic condi­
tions .
A WARNING
Although the ABS is very effective, always
remember that bra king capability is limit­
ed by t ire traction. Always adjust your dr iv­
ing speed according to the road and traffic
conditions . Do not let the extra sa fe ty af ­
forded bytheABStemptyou into taking
extra r isks. The ABS cannot overcome the
laws of physics.
(D Tips
- If ABS is not functioning properly, a
warning light will come on. See
¢ page 18.
- If a fault occurs in the ABS, the EDL is al ­
so not functioning . This is indicated by
the ABS warning light.
Brake assistant
The broke assistant is designed to achieve the
optimum broking effect .
The brake assistan t helps to increase the ef­
fective
b raking power and thus to achieve a
shorter stopping distance . If the driver
Int ellig ent technolog y 165
presses the brake peda l very quick ly, the brake
assistant automatically boosts the braking
force to the max imum level, up to the po int
where the anti-lock brake function (ABS) inter­
venes to stop the whee ls from locking. You
shou ld then keep the brake peda l pressed un ­
t il the vehicle has braked to the required
speed. The brake assistant switches itself off
as soon as you release the b ra ke peda l.
The brake ass istant wi ll not be operative if
there is a ma lfunction in the ABS.
A WARNING
P lease remember that the acc ident risk a l­
ways increases if you drive too fast, espe­
cially in corners or on a slippe ry road, o r if
you follow the vehicle ahead of yo u too
closely . An increased accident risk cannot
be compensated even by the brake assis ­
tant, so always mainta in a safe speed.
Electro-mechanical
power assist
The electro-mechanical power assist helps
the driver when steering .
The degree of power assist is electronically
matched to vehicle speed .
The power steering system assists the driver
so that he can steer the vehicle with reduced physical effort.
Power steering will not work if t he engine is
off . As a result, the steering wheel will be hard
to turn .
A WARNING
If the system deve lops a problem, you
must seek qualified professiona l assis­
tance.
(D Note
If there is an e lectronic malfunction, ser­
votronic
will still function like a conven-
tiona l power steering system, providing a
constant steering support force that is no
-
l onge r proportionate to the vehicle speed. ..,.

166 Intelligent technolog y
This is most noticeab le when turning the
steering whee l at low speeds (for examp le
when parking), -more effort will be re­
quired than usual.
- Be aware of the different than usual
steering response and adjust your steer­
i ng force accord ingly.
- Have the problem checked and set right
by an author ized Audi dealer as soon as
possible.
- If a steering malfunct ion occurs, this is
s ignaled with the
ts ~ or .• indicator
li ghts and a warning tone, see.
(D Tips
- If the power steering system shou ld fail,
or if the eng ine is not running (for exam­
ple, while being towed), you will st ill be
able to steer the veh icle. However, more
effort will be req uired to do so.
- If the power steering system is not func­
tioning properly, co ntact your authorized
A udi dealer immediate ly.
Driving with your
quattro ®
Appl ies to vehicles: with All Whee l Drive
With All Wheel Drive, all four wheels are driv ­
en.
General information
W ith All Whee l Dr ive, power is d istributed to
a ll fo ur wheels . This happens automa tic a lly
depending on your driv ing sty le and the road
conditions at the time . See also
¢ page 161.
Winter tires
When dr iv ing in the w inte r, your ve hicle w it h
A ll Whee l Drive has an advantage, even wi th
reg ular t ires. In win ter road condi tions it may
be adv isable to mo unt winter tires (o r all-sea ­
son tires) for improved driveability and b rak­
ing: these tires must be mounted on all four
wheels. See also ¢ page 22 7, Winter tires.
Snow chains
Where snow chains are manda to ry on ce rtain
roads, this norma lly also app lies to ve hicles
with all-wheel drive¢
page 228, Snow
chains.
Replacing wheels /tires
Vehicles with A ll Wheel D rive must a lways
have t ires o f the same s ize. A lso avoi d tires
with different t read depths . For deta ils see
page
¢ page 223, New tires and replacing
tires and wheels .
Off-Road driving?
Your Audi does no t have enough g round clea r­
ance to be used as an off-road vehicle .
It is
therefore bes t to avoid rough tracks a nd un ­
even terrain as much as possib le . Also refer to
¢ page 171.
A WARNING
-
Always ad just your dr iv ing to road and traf-
f ic conditions. Do not let the extra safety
afforded by the all-wheel dr ive tempt you
i nto ta king extra risks.
- Although the quattro ®all-wheel dr ive is
very effect ive, a lways remember that
b rak ing capac ity is limited by tire trac­
tion . You should therefore not d rive at
excessive speeds on icy or slippe ry road
sur faces.
- On wet road surfa ces, be careful not to
d rive too fast because the front whee ls
could begin to slide on top of the water
(hydroplaning). If this sho uld occ ur, you
will have no warning from a s udden in ­
crease in eng ine speed as w it h a front­
wheel d rive veh icle. Always drive at
speeds which are adjusted to the road
conditions - risk of c rash!

-Never mount used tires on yo ur vehicle if
you are not sure of their "previous histo­
ry." Old used tires may have been dam­
aged even though the damage cannot be
seen that can lead to sudden tire failure
and loss of vehicle control.
