button is not pulled within 5 seconds, the
disp lay reset mode closes.
(D Note
If yo u disconnect the battery terminals, no
ca lculations can be made for the service
interval display during this time and no
service reminder will appear. Remember
that observing the proper service intervals
is vitally important to extending the life of
your vehicle, particularly the engine, and maintaining its value . Even if the mileage
driven is low, the maximum period of one
year from one service to the next must not
be exceeded.

rapidly for 30 seconds and then blinks slowly.
How is the anti-theft alarm system
switched off?
The anti-theft a larm system is switched off
on ly when you use the remote contro l to un­
lock your veh icle. If you do not open a door
within 30 seconds after you have un locked
with the remote cont ro l, the vehicle will lock
itself again automatically.
If you lock just the dr iver's doo r using your
key, the front passenger's door and the rear
lid remain locked.
When will the anti theft alarm system be
triggered?
When the vehicle is locked , the alarm system
monitors and protects the following pa rts of
the vehicle:
- engine compa rtment
- luggage compartment
- doors
- ignition
When the system is activated, the alarm will be triggered if one of the doors, the engine
hood or the rear lid are opened, or if the igni­
tion is turned on.

• Push the lever~ fig. 70 -Arrow-~ .&,..
• Move the steering wheel to the desired po­
sition.
• Push the lever against the steering column
until it locks.
There must be at least 10 inches (25 cm) be­ tween your chest and the center of the steer­
ing wheel. If you cannot sit more than 10 in­
ches (25 cm) from the steering wheel, see if
adaptive equipment is available to help you
reach the pedals and increase the distance
from the steering wheel.
For detailed information on how to adjust the
driver's sea t, see
Q page 56 .
A WARNING
Improper use of steering wheel adjust­
ment and improper seating position can
cause serious personal injury.
- Adjust the steering wheel column only
when the vehicle is not moving to pre­
vent loss of vehicle control.
- Adjust the driver's seat or steering wheel so that there is a minimum of 10 inches
(25 cm) between your chest and the
steering wheel
~page 91, fig. 91. If
you cannot maintain this minimum dis­
tance, 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 with your au­
thorized Audi dealer to see if adaptive equipment is ava ilable .
- If the steering wheel is aligned with your
face, the supplemental dr iver 's airbag
cannot provide as much protection in an
accident. Always make sure that the
steering wheel is al igned with your
chest .
-Always hold the steer ing wheel w ith your
hands at the 9 o'clock and 3 o'clock posi­
tions to reduce the risk of persona l injury
if the driver's airbag deploys .
- Never hold the steering wheel at the 12

Braking
General information
What affects braking efficiency?
Ope rating cond itions and driving habits
The brakes on today's automobiles a re still
subject to wear, depe nd ing largely on operat ­
ing condit ions and driving hab its
c:> .&,. . On
vehicles that are either driven most ly in stop­
and-go city t raff ic or are dr iven hard, the
brake pads should be checked by yo ur au thor­
ized Audi dealer more often than specified in
the
Warr anty & Maintenance booklet. Failure
to have your brake pads inspected can result
in reduced brake performance.
On steep slopes, you should use the braking
effect of the engine. T his way, you prevent un­
necessary wear on the brake system . If you
must use your brakes, do not hold the brakes .,.

154 Intellig ent technolog y
down continuously. Pump the brakes at inter ­
va ls.
Noises may occur when braking depending on
the speed, braking force and outside condi­
tions such as temperature and humidity.
Moistu re or road salt
Under certain conditions, for examp le, when
d riving through water or ve ry heavy rain, or
even after washing your vehicle , the bra king
effect can be reduced due to moisture (o r in
freezing conditions ice) on the brake pads. A
few cautious brake applications should dry off
the brake pads or remove any ice coatings.
The effectiveness of the b rakes can be reduced
when the vehicle is driven on a salt -covered
road and the brakes are not used. Likewise,
you clean off accumulated sa lt coating from
brake discs and pads with a few caut ious ap­
plications of the brake
q .&. .
Co rrosion
There may be a tendency for dirt to bui ld up
on the brake pads and corrosion to form on
the discs if the car is not driven regularly or
only for short trips with little use of the brakes.
If the brakes are not used frequently, or if cor­ rosion has formed on the discs, it is advisable
to clean off the pads and discs by braking
f irmly a few times from a moderately high
speed
Q .&. .
Fa ults in th e brak e system
If you should notice a sudden increase in
brake peda l travel, then one of the two brake
circu its may have failed
q .&. .
Low brake flu id le vel
Malfunct ions can occur in the brake system if
the brake fluid level is too low. The brake fluid
leve l is monitored electronically.
B rake boo ste r
The brake booster increases the press ure that
you gene rate w it h the brake pedal. It works
on ly when the engine is running
.Q .&.
Brake lining wear statu s
Brake lining wear may be checked by visual in­
spection of the condition of the brake pads
thro ugh the openings in the wheel. If neces­
sary, the wheel may be removed for this in­
spection
q page 224, What should I be
aware of when changing a tire?.
A WARNING
-- You shou ld perform braking maneuvers
for the purpose of cleaning the brake system only if road conditions permit .
Othe r road use rs must not be put at risk -
you may ca use an accident!
- Before descend ing a steep grade, reduce
speed and sh ift transmission into a lower
gear or lower dr iving range. Do not ride
the brakes or hold the pedal down too
long or too often. This could cause the
brakes to get hot and diminish braking
efficiency.
- Do not "ride the brakes" by rest ing your
foot on the pedal when you do not intend
to brake. This may cause the brakes to
overheat, premature wear and increased
stopping distance .
- Under certain climatic and operat ing
conditions such as passing through wa­
ter, dr iving in heavy rain or after washing
the vehicle, the effectiveness of the b rakes can be reduced. In winte r, ice can
accumu late on the bra ke pads, lin ings,
d iscs and drums. Carefully app ly bra kes
for a test . Brakes will dry and ice coat­
ings will be cleaned off after a few care­
fu l brake applications.
- Driving for an extended period of time on salt-covered roads without using your brakes can a lso affect braking efficiency.
Clean off accumulated salt coating from
brake discs and pads with a few cautious
brake applications .
- If you damage the front spoiler, or if you
install a different spoiler, be sure the a ir
f low to the front brakes is not obstruct-
ed. Otherwise the brake system could
Ill>

overheat reducing the effectiveness of
the ent ire brake system.
- Failure of one brake circuit will impair
the braking capability resulting in an in­
creased stopp ing distance. Avoid driv ing
the vehicle and have it towed to the near­ est Aud i dealer or qualified workshop .
- Never let the vehicle roll to a stop w ith
the engine shut off.
- If the brake booster is not working, for
example when towing your ve hicle, or
because the brake booste r has somehow
been damaged, the brake pedal must be
pressed considerab ly harder to make up
for the lack of booster assistance.
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 steer ing system ass ists the driver
so that he can stee r the veh icle w ith red uced
phys ica l effort.
Power steering w ill not work if the engine is
off. As a result, the steering wheel w ill be hard
to turn.
& WARNING
If the system develops a prob lem, you
must seek qualified professional assis­
tance.
(D Note
-
If there is an electronic malfunct ion, ser­
votronic
wi ll sti ll function like a conven­
tional power steering system, providing a
constant steering support force that is no
longer proportionate to the vehicle speed.
This is most noticeable when turning the
steer ing wheel at low speeds (for example
when parking), -more effort will be re­
quired than usual.
Int ellig ent technolog y 155
-Be aware of the different than usual
steering response and adjust your steer­
ing force accordingly.
- Have the problem checked and set right
by an authorized Audi dea ler as soon as
possible.
- If a steering malfunction occurs, this is
signaled with the,~ , or .• indicator
lights and a warn ing tone, see.
(D Tips
- If the power steering system sho uld fail,
or if the engine is not running (for exam­
ple, while being towed), you will still be
able to steer the vehicle. However, more
effort will be required to do so.
- If the power steering system is not func­
tioning properly, contact your authorized
Audi dealer immediately.

General information
With a ll-wheel drive, power is distr ibuted to
all four wheels. This happens automatically
depend ing on your driving style and the road
conditions at the time. See also
c::> page 1 SO.
The all-whee l dr ive concept is des igned for

Winter tires
When dr iving in the winter, your vehicle with
all-wheel drive has an advantage, even with
regular tires. In winter road conditions it may
be advisable to mount winter tires (or all-sea­
son tires) for improved driveability and brak­
ing: these tires must be mounted on
all fou r
wheels. See also c::> page 211, Winter tires. ..,_

160 Driving and en vironm ent
Avoid damaging the
vehicle
When you are driving on poor roads, or over
curbs, steep ramps, etc ., make certain that
low-lying parts such as spoilers and exhaust
system parts do not bottom out and get dam­
aged.
This is especially true for vehicles with low­
slung chassis (sports chassis) and fully loaded
vehicles .
Driving through water
on roads
Note the following to avoid vehicle damage
when driving through water, for example on
flooded roads:
- T he water must not be any highe r tha n the
bottom of the vehi cle body.
- Do no t drive faster than wa lking speed.
_& WARNING
After d riving through water, m ud, slush,
etc., the brakes may be slow to take effect
because o f wet brake ro tors and pads . Dry
the brakes fi rst by braking carefully to re­
store the full braking effect.
(]) Note
Vehicle components such as the engine,
transmiss ion, suspension or electrical sys ­
tem can be severely damaged by driving
through water.
- Check the depth o f the water before driv ­
ing through it.
- Do not stop the veh icle, dr ive in reverse
or switch the engine
off when driving
through water.
- Keep in mind that oncoming vehicles may c reate waves that raise the water
l evel and make it too deep for your vehi­
cle to drive through safely.
- Avoid driving thro ugh salt water because
it can ca use corrosion.

Catalytic converter
It is very important that your emission con­
trol system (catalytic converter) is function­
ing properly to ensure that your vehicle is run­
ning in an environmentally sound manner.
.,. Always use lead-free gasoline ¢ page 176,
Fuel supply .
.,. Never run the tank down all the way to
empty .
.,. Never put too much motor o il in your en-
gine ¢
page 185, Adding engine oil 'l::r. .
.,. Never try to push- or tow-sta rt you r vehicle.
The catalyt ic converter is an efficient "clean­
u p" dev ice buil t into the exhaust system of
t h e vehi cle. The cata lytic conve rter bu rns
many of t he pollu tan ts in the exha ust gas be­
f ore they are re leased into the atmosphere.
T he exclusive use of unleaded fuel is critica lly
important for the life of the catalyt ic convert­
er and prope r fu nct ion ing of the engine.
A WARNING
- Do not park or operate the vehicle in
areas where the hot exha ust system may
come in contact with dry g rass, brush,
fue l spill or other material wh ich can
cause a fire.
- Do not app ly additiona l undercoating or
rustproofing on or near the exhaust
manifold, exhaust pipes, catalytic con­
verter or heat sh ields. Dur ing driv ing, the
substance used fo r undercoating could
overheat and cause a fire.
(D Note
- Be aware that just one tank filling with
leaded fuel will already ser iously de-
grade the performance of the catalytic
converte r.
- Do not exceed the correct engi ne oil level
¢page 185.
-Do not drive until the fuel tank becomes
completely empty . The engine co uld mis-
fire. Unburned fuel could also get into ..,.
