140 Automatic transmission
-Never hold the vehicle on an incline with
a slipping clutch. The clutch opens auto­
matically when it becomes too hot from
the overload. An indicator lamp
[O] illu­
minates and a driver message appears
c!;> page 141 when the clutch is overload­
ed.
- If the engine must remain running, never
have any driving position engaged when
checking under the hood. Make sure the
selector lever has securely engaged and
is locked in P with the parking brake
firmly set¢
page 257. Otherwise, any
increase in engine speed may set the ve­
hicle in motion, even with the parking
brake applied.
(D Note
- When stopping on an incline, do not try
to hold the vehicle in place by pressing
the accelerator peda l while a driving gear
is selected. This can cause the transmis­
sion to overheat and can damage it. Acti­
vate the park ing brake or press the brake
pedal to prevent the vehicle from rolling.
- Allowing the vehicle to roll when the en­
gine is stopped and the selector lever is
in
N will damage the transmiss ion be­
cause it is not lubricated under those cir­
cumstances.
Hill descent control
The hill descent control system assists the
driver when driving down declines.
H ill descent control is activated when these­
lector lever is in D/S and you press the brake
pedal. The transmission automatically selects
a gear that is suitab le for the incline. Hill de­
scent control tries to maintain the speed ach­
ieved at the time of braking, within physical
and technical limitations . It may st ill be nec­
essary to adjust the speed with the brakes.
Hill descent control switches off once the de ­
cline levels out or you press the accelerator pedal. When the speed
is set in the cruise control
system
c!;>page 111, hill descent control is al­
so activated.
A WARNING
--
Hill descent control cannot overcome
physical limitations, so it may not be able
to maintain a constant speed under all
conditions. Always be ready to apply the brakes.

Homelink
Universal remote
control
Description
Applies to vehicles: with Home link
The HomeLink universal remote control can
be programmed with the remote control for
devices that are already present.
With Home Link, you can control devices such
as the garage door, security systems, house
lights , etc. comfortably from the inside of you
vehicle.
Homelink makes it possible for you to rep lace
three different remote controls from devices
in your home with one universal remote. This
feature works for most garage door and exte­
rior door motor signals. Programming the in­
dividual remote control for your remote con ­
trol takes place on the left side of the front bumper. There is a control module attached at
this location .
A one-time programming of the sensor must be performed before you are able to use sys­
tems with Homelink. If the system does not activate after performing the one-time pro­
gramming, check whether the system uses a rolling code
¢ page 163 .
A WARNING
-Never use the Homelink transmitter
with any garage door opener that does
have not the safety stop and reverse fea­
ture as required by federa l safety stand­
ards. This includes any garage door open­
er model manufactured before April 1,
1982.
- A garage door opener which cannot de­
tect an object, signaling the door to stop
and reverse does not meet current feder­
al safety standards . Using a garage door
opener without these features increases
risk of serious injury or death.
Homelink 161
- For safety reasons never release the
parking brake or start the engine while
anyone is standing in front of the vehicle .
- A garage door or an estate gate may
sometimes be set in motion when the
Homelink remote control is being pro­
grammed. If the device is repeatedly ac­
tivated, th is can overstrain motor and
damage its electrical components - an
overheated mo to r i s a fire hazard!
- To avoid possib le injuries or property
damage, please always make abso lutely
certa in that no persons or objects are lo­
cated in the range of motion of any
equipment being operated.

Pedal area
Pedals
The pedals must always be free to move and
must never be interfered with by a floor mat
or any other object.
Make sure that all pedals move freely without
interference and that nothing prevents them
from returning to their original positions .
Only use floor mats that leave the peda l area
free and can be secured with floor mat fasten­
ers .
If a brake circuit fails, increased brake peda l
travel is required to bring the vehicle to a
full
stop.
A WARNING
Pedals that cannot move freely can cause
loss of vehicle control and increase the r isk
of serious injury.
- Never place any objects in the driver's
footwell. An object could get into the
peda l area and interfere w ith pedal func­
tion. In case of sudden braking or an ac­
cident, you would not be able to brake or
accelerate!
- Always make sure that nothing can fall
or move into the driver's footwell.
Floor mats on the driver side
Always use floor mats that can be securely
attached to the floor mat fasteners and do
not interfere with the free movement of the
pedals.
"' Make su re that the floor mats are properly
secu red and cannot move and interfere with
the pedals ~
A,.
Use o nly floor mats that leave the pedal a rea
unobstructed and that are firmly secured so
that they cannot s lip out of position. Yo u can
obtain suitable floor mats from your author­
ized Audi dealer.
Floor mat fasteners are installed in your Audi .
Driving S afel y 169
Floor mats used in your vehicle must be at­
tached to these fasteners . Properly securing
the f loor mats will prevent them from sliding
into positions that could interfere with the
pedals or impair safe operat ion of your vehicle
in other ways.
A WARNING
Pedals that cannot move freely can result
in a loss of vehicle control and increase the
risk of serious persona l injury.
- Always make sure that floor mats are
properly secured.
- Never p lace or install floor mats or other
f loor coverings in the vehicle that cannot
be properly secured in place to prevent
them from slipping and interfer ing with
the peda ls or the ability to contro l the
vehicle .
- Never place or install floor mats or other
f loor coverings on top o f already instal­
led floor mats . Additiona l floor mats and
other coverings will reduce the size of
the pedal area and interfere with the
pedals.
- Always properly reinstall and secure floor
mats that have been taken out for clean­
ing.
- Always make sure that objects cannot
fall into the dr iver footwell while the ve­
hicle is moving . Objects can become
trapped under the brake pedal and accel­
erator pedal causing a loss of vehicle
control. •

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 fo r the express purpose of capturing
data for retrieval after an accident or crash
event . EDRs are sometimes ca lled "crash re­
corders".
Some state laws restrict the retr ieval or down­
loading of data stored by EDRs 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.
A lthough 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 contro l modules also record
vehicle-related data during normal 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
The Electronic Stabilization Control (ESC) rein­
forces driver safety. It reduces the risk of slip ­
p ing and improves driving stability. ESC de­
tects cr itical s ituations such as the vehicle oversteering and
understeering or the wheels
spinning . The vehicle is stabilized by applying
the brakes or reducing engine torque . Once
the ESC is active, the indicator light
G1 blinks
in the instrument cluster.
ESC includes the anti-lock brake system (ABS),
brake assist system, anti-slip regulation
(ASR), electronic differential lock (EDL) and
hill descent control.
Anti-lock brake system (ABS)
ABS prevents the whee ls from locking up
when braking. The vehicle can still be steered
even during hard braking. App ly steady pres­
sure to the brake pedal. Do not pump the ped­ al. A pulsing in the brake pedal indicates that
the system is helping you to brake the vehicle .
Brake assist system
The brake assist system can decrease braking
distance. It increases braking power when the
driver presses the brake pedal quickly in emer­
gency situations. You must press and hold the
brake pedal until the situation is over . In
vehicles with adaptive cruise control*, the
brake assist system is more sensitive if the
distance detected to the vehicle ahead is too
small.
Anti-slip regulation (ASR)
ASR reduces engine power when the drive
wheels begin to spin and adapts the force to
the road conditions. This makes it easier to
sta rt, accelerate and drive up hills.
Electronic differential lock (EDL)
The EDL brakes wheels that are spinning and
transfers the drive power to the other wheels .
This function is available up to about 60 mph
(100 km/h) .
In extreme cases, EDL automatically switches
off to help keep the brake on the braked wheel
from overheat ing. EDL will switch on again au­
tomat ically when conditions have returned to
normal.

Hill descent control
The hill descent control is switched on in off­
road mode. When slowly descending steep
gradients on loose ground or when the axles
are articulated, h ill descent control provides
assistance by automatically applying the
brakes to keep vehicle speed constant. The ve­
h icle is also rendered easier to steer by selec­
tive distribution of braking force . Hill descent
control intervenes when:
- the accelerator pedal is not pressed,
- the vehicle is trave lling less than 12 mph
(20 km/h),
- a steep gradient is detected,
-wheel behavio r indicates loose ground or
conditions with poor adhesion (e .g. also ax le
articulation) .
H ill descent control operates both driving for ­
ward and in reverse . Active hill descent con­
trol is deactivated by pressing the accelerator
pedal until the conditions for activation al ­
ready listed are met again.
A WARNING
You should only switch offroad mode on if
your dr iving abilities and road cond itions
permit.
- The stabilization function is limited
when offroad mode is switched on. The
dr iv ing wheels could spin and the vehicle
cou ld swerve, especially on slick or slip­
pery road surfaces.

Brake system
Operating conditions and driving habits
The brakes on today's automobiles are still
subject to wear, depending largely on operat­
ing conditions and driving habits
c> Li::,. . On
vehicles that are either driven most ly in stop­
and-go city traffic or are dr iven hard, the
brake pads should be checked by your author­
ized Audi dealer more often than specified in
the Warranty & 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 . This way, you prevent un­
necessary wear on the brake system .
If you
must use your brakes, do not hold the brakes
down continuously. Pump the brakes at inter­
vals.
Noises may occur when braking depending on
the speed, b raking force and outs ide cond i­
tions such as temperature and humidity.
Moisture or road salt
Under certain conditions, for example, when
driv ing through water or very heavy rain, or
even after washing your veh icle, the braking
effect can be reduced due to moisture (or in
freezing conditions ice) on the bra ke pads. A
f ew careful brake applications should dry off
the brake pads or remove any ice coatings.
jll,,

When you are driving at higher speeds wit h
the windshield wipers on, the brake pads will briefly touch the brake d iscs in regular inter­
vals so as to improve reaction t ime when brak­
ing on wet surfaces. You, the driver, will not
notice anything .
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 coat ing
from brake discs and pads with a few careful
applications of the brake ¢ & .
Cor ro sion
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 dr iven regularly or
only for sho rt trips with little use of the
b rakes .
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 b rak ing
fi rm ly a few times from a mode rately h igh
speed ¢.& .
Faults in the brake system
If you should notice a sudden increase in
brake peda l travel, t hen one of the two brake
circu its may have failed¢& .
Low brake flu id le vel
Malfunct ions can occur in the brake system if
the brake fl uid level is too low . T he brake fluid
level is monitored electronically .
Brake booste r
The brake booster increases the pressure t hat
you generate w ith the bra ke pedal. It on ly op­
erates while the eng ine is running¢ &.
Brake lining wear statu s
Brake lining wea r may be c hecked by vis ual in­
spection of the condition of the brake pads
through the openings in the whee l. If neces ­
sary, the whee l may be removed for this in­
spection ¢

A WARNING
-You should 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 a nd s hift transmission into a lower
gea r o r l ower dr iving range. Do not ride
the br akes or ho ld t he pedal down too
long o r too often. This could cause the
brakes to get hot and diminish braking
efficiency .
- Do not " ride the brakes" by rest ing you r
foot on the pedal when you do not intend
to brake. This may ca use the brakes to
overheat, premature wear and increased
stopping distance .
- Under certain cl imatic and ope rat ing
conditions such as passing thro ugh wa­
ter , dr iv ing in heavy rain o r after washing
the vehicle , the effectiveness of the
brakes can be reduced . In winte r, ice can
accumu late on the bra ke pads, lin ings,
d iscs a nd drum s. Carefu lly app ly bra ke s
for a test. Brakes w ill dry and ice co at­
ings w ill be cleaned
off after a few care­
fu l brake applicat ions.
- Driving for an exten ded period o f time o n
salt -cove red roads without using your
brakes can a lso affect braking efficiency .
C lean
off accum ulated salt coating from
brake discs and pads with a few careful
brake applications.
- I f you damage the front spoiler, o r if you
install a different spoiler, be sure the air
f low to the front brakes is not obstruct­
ed. Otherw ise the brak e system could
overheat reducing the effectiveness of
the entire brake system.
- Failure of one b rake circuit will impai r
the braking capab ility result ing in an in­
creased s topping distance. Avoid driving
the vehicle a nd have it towed to the ne ar­
est a uthorized Audi dea le r or qu alified
wo rkshop.

228 Intellig ent technol ogy
- Never let the vehicle ro ll to a stop with
the engine shut off.
- If the brake booster is not working, the
brake pedal must be pressed considera­
bly harder to make up for the lack of
booster assistance.
Servotronic - advanced
power steering system
The power steering systems uses the power of
the running engine to allow precise steering
with little effort.
The advanced Servotronic power steering sys­
tem senses the road speed and electronically
adjusts powe r assistance to provide comforta­
b le and safe steering response exact ly match­
ed to the vehicle speed.
Power steering w ill not work if the eng ine is
off. As a result, the steering wheel w ill be hard
to turn.
The power steering fluid level is checked dur­
ing the scheduled ma intenance serv ices .
@ Note
If the re is an electronic malfunct ion, ser­
votronic
w ill still function like a conven­
tional power steer ing system, p roviding a
constant steer ing support force that is no
longer proportionate to the vehicle speed .
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 usua l
steering response and adjust your steer­ i ng force accord ingly.
- Have the prob lem checked and set right
by an Aud i dealer as soon as possible.
- When the engine is running , never hold
the steering whee l turned all the way to
the right or to the left for longer than
15
seconds . The power steer ing pump w ill
overheat the hydraulic flu id if you keep holding the steering wheel turned all the
way . This is likely to damage the power
steering system.
- If the powe r stee ring system sho uld fail
entirely, or if the engine is not running
(for example, whi le be ing towed), you
will still be able to steer the ve hicle.
However,
considerably more effort will
be required to do so .
- If the power steering system should
have a leak, or is not functioning proper­
ly, contact your author ized Audi dealer
immediately .
- The power steering system requ ires a
specially formulated hyd ra ulic fluid . The
powe r stee ring reservoir is the one locat­
ed farthest to the rear on the left s ide of
the engine comp artment r=;,
page 259.
T he 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 driv­
en .
Gen eral information
With all-wheel drive, power is distributed to
all four wheels. This happens au toma tically
depending on your driving style and the road
condit ions at the time . See also r=;,
page 224 .
Winter tire s
When driving in the winter, yo ur vehicle with
a ll-wheel drive has an advantage, even wi th
regular tires . In winter road conditions it may
be advisable to mount winter tires (or all -sea ­
son tires) for improved dr iveability and brak­
ing : these tires must be mounted o n
all four
wheels. See also r=;, page 288, Winter tires.
Tire chains
Where tire chains are mandatory on certain
roads, this normally also appl ies to veh icles
with all-wheel driver=;,

The first 1,000 miles
(1,500 km) and
afterwards
New engine
The engine needs to be run-in during the first
1,000 miles (1,500 km).
For the fir st 600 miles (1,000
kilometers ):
.,. Do not use full throttle.
... Do not d rive at engine speeds that are more
than 2/3 of the max imum permitted RPM.
From 600 to 1,000 miles (1 ,000 to
1,500 kilomete rs):
.,. Speeds can gradually be increased to the
max imum pe rm iss ible road or eng ine speed .
During and after break-in per iod
... Do not rev the eng ine up to high speeds
when it is cold. Th is app lies whether the
transmission is in N (Neutra l) or in gear.
After the brea k-in period
... Do not exceed max imum engine speed un­
der any circumstances.
... Upshift into the next higher gear before
reaching the red area at the end of the tach­
ometer scale¢ page 10.
During the first few hours of driving, the en­
g ine's inter na l friction is higher than later
when all the moving parts have been broken
i n. How well this break- in process is done de­
pends to a conside rable extent on the way the
ve hicle is driven du ring the first 1,000 miles
(1, 500 kilome ters).
(D Note
E xtremely high engi ne speeds are auto­
mat ica lly r educed. However, these rpm
lim its are programmed for a n engine well
r u n- in, not a new eng ine.
{® For the sake of the environment
Do not drive with unnecessarily high en­
g ine speeds - upshifting ear ly saves fuel,
reduces no ise and protects the environ­
ment.
, New tires
If your vehicle is runni ng on new tires, drive
part icularly caref ul for the first 350 miles
(500 kilomete rs) afte r fitt ing.
A WARNING
N ew tires tend to be sl ippery and mus t al­
so be "b roken -in" . Be s ure to remember
this dur ing the fi rst 350 mi les (500 kilo ­
meters) . Brake gently . Avoid fo llow ing
closely behind other vehicles or other sit­
uations that m ight require sudden, hard
braking.
New brake pads
Remember that new brake pads do not have a
full bra king effect dur ing the fi rst 250 m iles
(400 kilomete rs) afte r they a re insta lled.
New brake pads have to be "burnished in" be­
fo re t hey have optima l grab¢
A .
During the break- in period, you should avoid
putting severe loads on the brakes. Severe
l oads include, for example, sudden hard brak­
i ng, in particular at very high speeds or, for
example, on mounta in passes .
A WARNING
New b rake pa ds don't have t he bes t stop­
pi ng power and mus t be "broke n-in " dur­
i ng the in iti al 1 00 to 150 mi les (150 to
20 0 kilometers) of no rma l city driving . You
can compensate for this by pressing the
