If the warning light in the instrument cluster flashes for approxi­
mately one minute and then remains continuously illuminated and
additionally the
JIS => fig . 28 symbol appears in the display , the
tire pressure monitoring system is not available. This can have
various causes.
• If the message appears at the end of the learning process, the
system cannot recognize the wheels installed on the vehicle. This
can be because one or more wheels without a whee l sensor were
insta lled .
• A wheel sensor or other component may have failed .
• During initialization the system has detected more than 4 whee ls
on the vehicle, for examp le while driving next to another car with a

Adaptive Air Suspension
Air suspension and damping
Applies to vehicles: with Adaptive A ir Suspens ion
Description
Air suspension and damping can be regulated as desired
by driver, and they adapt automatically to the driving situ­
ation at the time.
Adaptive Air Suspension is an electronica lly contro lled springing
and damping system. This chassis system makes it easier on the
driver by adapting to the particular situation through imperceptible
control processes.
The
Adaptive Air Suspension component regulates ground clear ­
ance depending on vehic le speed and driver inpu t. It functions inde­
pendently from the load condition. Accelerating to a speed above a
predetermined limit will make the vehic le lower itself . On the other
hand, driving more slowly results in the vehicle raising again at
specific speeds.
The
damping component provides individual control of the
damping forces. For example, with damping characteristics set to
provide greater comfort, damping is set somewhat harder for a brief
period only as required, for example, when going around a curve or
when braking.
Settings
Adaptive Air Suspension prov ides the driver with the opportunity to
set the chassis characteristics a lso to their individual preference.
With the driving modes
comfort, automatic and dynamic the driver
has three chassis settings available, ranging from comfort to sporty.
The
offroad mode can be selected for driving on poor qua lity
stretches of road. In addition, lift provides a fifth mode, which can
be selected when exceptionally high ground clearance is needed
=> page 207, "Chassis controls". The modes are set in
MMI:::::,
page 208.
& WARNING
The height of the parked vehicle can change due to temperature
fluctuations or changes in load.
0 Note
• Whenever you park your vehicle, always make sure there is
adequate clearance above and below the vehic le. The height of the
parked vehicle can change as the result of temperature fluctuations,
changes in load condition and changes in the driving mode (ground
clearance!.
• If the vehicle is being transported (e.g. by tow truck, train, ship,
etc.), mount the tie -down chains/cables over the running surface
(circumference) of the tires . Never secure the veh icle by the axle, the
suspension struts or the front or rear towline eye. For technical
reasons, the pressure in the suspension struts may change during
the transport, which could result in the vehic le no longer being
secured properly.
• If you are going to tow a trailer with a trailer hitch that was
not
installed according to factory specifications, you must activate the
trailer operation mode manually:::::,
page 211.
[ i ] Tips
• Before you can raise your vehic le using the vehicle jack (for
example, when changing a flat tire) or a vehicle lift, you must acti­
vate the jacking mode:::::,
page 210.
• On some models, the vehicle can reach its maximum speed only
in the
automatic and dynamic modes. •

tendency to spin and the vehicle may break away -danger of skid­
ding!
• Stability is limited in the ESP offroad mode. •
Electronic differential lock (EDL)
The electronic differential lock monitors the rotational
speed of the drive wheels.
General notes
The electronic differential lock (EDU helps the car to start moving,
accelerate and climb a gradient on surfaces providing poor or
almost no grip . Without EDL, this would be difficult, if not impos­
sible.
How the system works
The EDL operates automatically. It monitors the rotational speed of
wheels with the help of the ABS sensors=> page 292. If a noticeable
slip is detected at the wheels (e.g. on slippery ground on one side),
the spinning wheels are braked and power is transferred to the
other wheels. This is done up to a speed of about 60 mph (100 km/h).
Noises from the brake system signal that wheel spin is being
controlled.
Driving off
When driving off, always be sure to keep road conditions in mind as
you accelerate. If one drive wheel spins because it is on a surface
with less grip, apply plenty of throttle until the car starts to move.
Overheating of brakes
To prevent the disc brake of the braked wheel from overheating if
subjected to excessive loads on this wheel, the EDL cuts out tempo­
rarily. The vehicle remains operational and behaves in the same way
as a vehicle without EDL. As soon as the brake has cooled down, EDL switches on again auto­
matically.
& WARNING
• When accelerating on slippery surfaces, such as on ice or snow,
always be careful when depressing the accelerator pedal . Even
with the EDL working, the drive wheels can spin and reduce your ability to control your car. Risk of crash!
• The increased safety afforded by EDL does not mean that you
can take safety risks. Always adapt your driving style to the road
conditions and traffic situation.
[ i] Tips
If a fault occurs in the ABS, the EDL is also not functioning. This is
indicated by the ABS warning light=> page 22. •
Anti-Slip Regulat ion System (ASR)
The Anti-Slip Regulation System prevents the driven
wheels from spinning when the car is accelerating.
General notes
The Anti -Slip Regulation System (ASR) is integrated in the electronic
stabilization program (ESP) . When the vehicle starts up and acceler­
ates, the wheels are prevented from spinning by adjusting the
engine power to match the amount of grip available from the road
surface.
How the system works
ASR performs automatically, i.e. without the driver's intervention.
With the aid of the ABS sensors=> page 292, ASR monitors the
speed of the driven wheels. If the wheels start to spin, engine torque
is reduced automatically until the tires find enough grip to lock onto
the road surface. The system is active across the entire speed range . ..,

The ASR works in conjunction with the ABS. If a malfunction should
occur in the ABS, the ASR wil l also be out of action.
& WARNING
The increased safety afforded by ASR does not mean that you can
take safety risks. Always adapt your driving style to the road
conditions and traffic situation.
[ i ] Tips
To ensure that the ASR works properly, all four wheels must be fitted
with identica l tires. Any differences in rolling radius of the tires can
cause the system to reduce engine power when this is not desired.

Braking
General information
What affects braking efficiency?
Operating conditions and driving habits
The brakes on today's automobiles are still subject to wear,
depending large ly on operating conditions and driving habits~& .
On vehicles that are either driven mostly in stop-and-go city traffic
or are driven hard, the brake pads shou ld be checked by your autho ­
rized Audi dealer more often than specified in the
Warranty & Main­
tenance booklet.
Failure to have your brake pads inspected can
result in reduced brake performance.
On steep slopes, you shou ld use the braking effect of the engine .
This way, you prevent unnecessary wear on the brake system. If you
must use your brakes, do not hold the brakes down continuously.
Pump the brakes at intervals.
Controls and equip­
ment Safety first Vehicle operation
Intelligent technology
Moisture
or road salt
If you are driving faster than 3 1 mph (50 km/h) and the windshield
wipers are on, the brake pads will briefly touch the brake discs in
regular intervals so as to improve reaction time when braking on
wet surfaces. You, the driver, will not notice anything.
Under certain conditions, for example, when driving through water
or very heavy rain, or even after washing your vehicle, the braking
effect can be reduced due to moisture (or in freezing conditions ice)
on the brake pads. A few careful brake applications sho uld dry off
the brake pads or remove any ice coatings .
The effectiveness of the brakes can be reduced when the vehicle is driven on a salt -covered road and the brakes are not used. Here too,
you should clean off accumulated salt coating from brake discs and
pads with a few carefu l app lications of the brake ~& .
Corrosion
There may be a tendency for dirt to build 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 litt le use of the brakes.
If the brakes are not used frequently, or if corrosion has formed on
t he discs, it is advisable to clean off the pads and discs by braking
firm ly a few times from a moderately high speed~&.
Faults in the brake system
If you shou ld notice a sudden increase in brake peda l trave l, then
one of the two brake circuits may have failed~& .
Low brake fluid le vel
Malfunctions can occur in the brake system if the brake fluid level is
too low . The brake fluid level is monitored electronically .
Brake lining wear status
Brake lining wear may be checked by visual inspection of the condi ­
tion of the brake pads through the openings in the wheel. If neces­
sary, the wheel may be removed for this inspection

0 Note
If there is an electronic malfunction, servotronic will still function
like a conventional 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 steering wheel at
low speeds ( for example when parking), - more effort will be
required than usual.
• Be aware of the different than usual steering response and
adjust your steering force accordingly.
• Have the problem checked and set right by an Audi dealer as
soon as possible.
[ i] Tips
• When the engine is running, never hold the steering wheel
turned all the way to the right or to the left for longer than 15
seconds . Th e power steering pump will overheat the hydraulic fluid
if you keep holding the steering wheel turned all the way. This is
likely to damage the power steering system .
• If the power steering system should fail entirely, or if the engine
is not running (for example, while being towed), you will still be able
to steer the vehicle. However,
considerably more effort will be
required to do so.
• If the power steering system should have a leak, or is not func­
tioning properly, contact your authorized Audi dealer immediately.
• The power steering system requires a specially formulated
hydraulic fluid. The power steering reservoir is the one located
farthest to the rear on the left side of the engine compartment
=>
page 332. The correct fluid level in the reservoir is important for
proper functioning of the power steering. •
Driving with your quattro®
---------
With All Wheel Drive, all four wheels are driven.
General information
With All Wheel Drive, power is distributed to all four wheels. This
happens automatically depending on your driving style and the
road conditions at the time. See also=>
page 290, "Electronic differ ­
ential lock (EDU" .
Winter tires
When driving 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-season tires) for improved
driveability and braking: these tires must be mounted on
all four
wheels .
See also=> page 363, "Win ter tires".
Tire chains
Where tire chains are mandatory on certain roads, this normally
also applies to vehicles with All Wheel Drive=>
page 364, "Snow
chains".
Replacing wheels/tires
Vehicles with All Wheel Drive must always have tires of the same size. Also avoid tires with different tread depths. For details see
page=:>
page 359, "New tires and replacing tires and wheels".
& WARNING
Always adjust your driving to road and traffic conditions. Do not let the extra safety afforded by All Wheel Drive tempt you into
taking extra risks .
• Although the All Wheel Drive is very effective, always
remember that braking capacity is limited by tire traction. You
should therefore not drive at excessive speeds on icy or slippery
road surfaces .

Driving and environment
The first 1,000 miles (1,500 km) and afterwards
!\Jew engine
The engine needs to be run-in during the first 1,000 miles
(1,500 km).
F o r th e fir st 600 mil es (1,000 kilomet ers):
Do not use full throttle.
- Do not drive faster than 3/4 of the top speed marked on
the speedometer.
- Avoid high engine speeds .
From 600 t o 1,000 mil es (1,000 t o 1,500
kil om eter s):
- Speeds can
gradually be i ncreased to t he maximum
permiss ible road or engine speed .
During and aft er br eak-in p eri od
- Do not rev the engine up to high speeds when it is cold. This applies whether the transm ission is in N (Neutral) or
1n gear.
Aft er the br eak-in p eriod
- D o not exceed max imum e ngine speed unde r any
circumstances.
- Upshift into the next higher gear
before reac hing the red
area at the end of the tachome ter scale ~

Controls and equip­
ment Safety first Vehicle operation
Dri
ving and environm ent
During the first few hours of driving, the eng ine's internal friction is
higher than later when all the moving parts have been broken in.
How well this break -in process is done depends to a considerable
extent on the way the vehicle is driven during the first 1,000 miles
(1,500 ki lometers).
0 Not e
Extreme ly high engine speeds are automatically reduced. However,
these rpm limits are programmed for an engine well run-in, not a
new engine .
~ For the sake of the environment
Do not drive with unnecessarily high engine speeds -upshifting
early saves fuel, reduces noise and protects the environment .
New tires
If your v ehic le is running on new tires, driv e particularly
carefu l for the first 350 miles (500 ki lometers) after fitting.

- Lack of proper maintenance as wel l as improper use of the
vehic le wi ll impair the func tion of the emission con tro l system
and could lead to damage.
<£> For the sake of th e envir onm ent
Even when the Emission Control System is operating properly, the
exhaust gas can have a su lfur -like exhaust gas smell under some
operating states . This depends on the sulfur content of the fuel
being used. Using a different brand of fue l may help, or filling the
tank with lead-free super grade gasoline. •
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 spoi lers and exhaust
system parts do not bottom out and get damaged.
This is especially true for vehicles with low-slung chassis (sports

Operate your vehicle economically
and minimize pollution
General
Your personal style of driving will determine the economy
of your vehicle, as well as exhaust and noise levels.
Fuel economy, environmental impact, and wear on your engine,
brakes and tires largely depend on three factors:
• your personal driving style
• operating cond itions
• technica l limitations

ving and environm ent
If you anticipate what you need to do next and drive economica lly,
you can easily cut your fuel consumption by 10 -15 percent . This
section wil l give you some tips on how you can help the environ­
ment and your pocketbook.
[ i ] Tips
The consumption estimates as published by ENV IRONMENTAL
PRO TEC TION AGENCY (EPA) and Transport Canada may not corre ­
spond to your actua l consumption on the road, which wi ll vary
depending upon vehic le load and speed, road and weather condi­
tions, trip length, etc. •
Drive smoothly and keep a lookout ahead
Vehicles use the most fuel when they ore accelerating.
-Avoid unnecessary accelerat ing and braking.
Vehicles use the most fuel when they are accelerating . If you antici­
pate what is going to happen next, you wi ll need to brake less and,
thus, acce lerate less. Let the vehicle coast whenever possib le - for
examp le when you see that the next traffic light is red. •
Avoid full throttle
Driving at moderate speeds saves fuel and improves your
mileage.
-Try and keep well below your car 's max imum speed.
Acce lerating gently reduces fue l consumption , engine wear, and
does not disturb the environment.
Fue l consumption, exhaust emissions and engine noise increase
disproportionately at high speeds . If you drive at approximate ly
three quarters of top speed, fuel consumption wil l be reduced by
