A WARNING
You should only switch sport mode on or switch ESC/ASR off if your driving ab ilities and
road condit ions perm it.
- The stabilization function is limited when
sport mode is switched on. The dr iving
wheels could sp in and the veh icle could
swerve, especially on slick or slippery road
surfaces.
- There is no vehicle stabilization when ESC/
ASR are switched off.
(D Tips
- ESC/ASR cannot be switched off or sport
mode cannot be sw itched on if the cru ise
control system* or the adapt ive cruise con­
trol* is switched on.
- Malfunctions in the Audi magnetic r ide may
make it impossible to sw itch the ESC/ASR
off or to switch spo rt mode o n.
Brakes
New brake pads
New brake pads do not achieve their full braking
effect during the first 250 mi (400 km). They
must be "broken in" f irst. Howeve r, you can com­
pensate for the slightly reduced braking force by
press ing firmly on the b rake pedal. Avoid heavy
braking during the break -in period.
Wear
Brake pad wear is large ly dependent on the way
the veh icle is d riven and on operating co nditions.
This is especially t rue if you are driving frequent ly
in the city and on cu rves or with a sporty driving
style.
Operating noise
Noises may occur when braking depending on the
speed, b rak ing force and o utside conditions s uch
as tempe rat ure and h umid ity.
Effect of water and road s alt
In certain situat ions, for example after driving
throug h wate r, in heavy ra in, after overn ight con­
densat ion or afte r wash ing you r car, the braking
In te llig ent T echnolog y
effect can be reduced by moisture or ice on the
brake rotors and brake pads . The brakes must be
"dried" first with a few careful brake applications.
At higher speeds and with the windsh ield wipers
turned on, the brake pads press against the b rake
rotors for a short amount of time . This action
wh ich is not felt by the driver happens at regular
intervals and facilitates a better reaction t ime for
the brakes in wet weather.
The braking effect can a lso be reduced if you are
driv ing on salted roads and you do not apply the
brakes for long periods of time. The layer of salt
on the brake rotors and pads must be worn off
first whe n the brakes a re applied .
Corro sio n
Leav ing the ve hicle parked for long periods of
t ime, low mileage and avoiding heavy braking can
contribute to corros ion on the brake rotors and
dirty brake pads.
If you usua lly avoid heavy b raking or if there is
corrosion present, occas ional heavy braking at
high speeds is recommended to clean the brake
rotors and pads¢,&.
Brake sy stem malfunct ion
if you notice that the b rake pedal travel has sud­
denly gotten larger, then a brake circ uit may have
failed. Drive to an authorized Audi dealer or au ­
thori zed Audi Service Facility immediately to have
the problem cor rected. On the way there, dr ive
with reduced speed and keep in mind that a long
braking distance and increased pressu re on the
brake pedal will be necessa ry.
Low br ake fluid level
When the brake f lu id level is low, malfunct ions in
the brake system may occur. The brake flu id leve l
is electronically mon itored.
Brake boo ste r
The brake booster amplifies the pressure yo u ap­
ply to the brake peda l.
It only works when the en-
gine is running.

Intelligent Technology
& WARNING
-New brake pads do not achieve their full
braking effect during the first 250 mi
(400 km). They must be "broken in" first .
However, you can compensate for the slight·
ly reduced braking force by pressing firmly
on the brake pedal. Avoid heavy braking dur·
ing the break-in period.
- Alway apply the brakes for the purpose of
cleaning the brake system when road and
traffic conditions permit. You must not en·
danger other road users. This increases the
risk of an accident.
- On steep slopes , reduce the speed and se­
lect a lower gear or lower selector lever po·
sition. Drive as little as possible while press· ing the brake pedal and avoid putting your
left foot on the brake pedal while driving.
This could cause the brakes to overheat and impair the efficiency of the brakes .
- Do not let the brakes "grind" by always
keeping your foot on the brake pedal. This
can cause the brakes to overheat, increase
wear and increase braking distance unneces·
sarily.
- Certain weather and operating conditions
such as driving through water, driving in
heavy rain or driving after washing your
ve·
hide can impair the effectiveness of the
brakes. In the winter, ice may build up on
the brake pads, rotors and drums. Check
these components by braking carefully. Ap·
plying the brakes carefully several times
dries the brakes and removes ice build-up .
- The efficiency of the brakes can also be im·
paired by driving for long stretches on roads
covered with salt without using the brakes.
You can
remove salt deposits from the brake
rotors and pads by carefully applying the
brakes several times.
- If the front spoiler is damaged or you install
another spoiler, make sure the front wheel
brakes are ventilated properly . Otherwise,
the brake system could overheat, which re·
duces their effectiveness.
- Failure of a brake circuit impairs braking
performance, which increases braking dis·
126
tance. Avoid driving the vehicle and have it
towed it to the nearest authorized Audi
dealer or authorized Audi Service Facility .
- Never let the vehicle roll while the engine is
stopped because this increases the risk of an
accident .
-If the brake booster is not working, you will
have to press much harder on the brake ped·
al to compensate for the lack of the booster .
(D Note
-Never let the brakes "rub" by pressing the
pedal lightly when braking is not really nee·
essary. This causes the brakes to overheat
and increases braking distance and causes
wear .
- Before driving on a long stretch with steep
slopes, reduce your speed and shift to the
next lower gear This makes use of the en·
gine braking effect and relieves the brakes .
If you need to brake additionally, brake in
intervals and not continuously.
(D Tips
-If the brake booster is not working, you
must press the brake pedal with much more
force then normal.
- If you retrofit your vehicle with a front spoil·
er, wheel covers or similar items, make sure
that the air flow to the front wheels is not
interrupted. Otherwise the brake system
can become too hot.
Electromechanical
steering
The electromechanical steering supports the
driver's steering movements .
Power steering adapts electronically based on
the vehicle speed.
T he vehicle still has full steering functionality if
the power steering fails or when the engine is
stopped (towing). To steer, you must apply much
more force than usual.

• Do not drive vehicle: steering defective

Care and cleaning
& WARNING
- Only wash the vehicle when the ignition is
off an d follow the i nstructions fr om the car
wash operator to r educe the r isk of acci­
dents.
- To reduce the r isk of cuts, protect yourself
from sharp metal components when wash­ ing the underbody or the inside of the wheel
hous ings.
- After washing the vehicle, the braking effect
may be delayed due to moisture o n the
brake rotors or i ce in the winte r. T he bra kes
mus t be d ried first w ith a few caref ul bra ke
applications .
@ Note
-If you wash the ve hicle in an au tomatic car
wash, you m ust fold the e xterior m irrors in
to reduce the ris k of damage to the mirrors .
Power folding exterior mirrors* must only
be fo lded i n and out using the power folding
funct ion. -
To prevent paint damage, do not wash the
vehicle in direct sunlight.
- T o reduce the r is k of damage to the sur face,
do not use insect remov ing sponges, kitchen
sponges or similar items.
- Mat te finish painted vehicle components:
- To reduce the risk of damage to the sur-
face, do not use po lishi ng agents or hard
wax.
- Never use protective wax.
It can destroy
the matte finish effect.
- Do not place any stickers or magnet ic
signs on vehicle parts painted w ith matte
finish paint. The pa int co uld be damaged
when the sticke rs o r mag nets are re­
moved.
@ For the sake of the environment
Only wash the ve hicle in facilities spec ially de­
s igned fo r that purpose. This w ill reduce the
r isk of dir ty wa ter co ntaminated w ith oil from
entering the sewe r system.

After you have loosened all wheel bolts and
raised the vehicle
off the ground, remove and re­
place the whee l as fo llows:
Removing the wheel
.,. Use the hexagonal socket in the screwdriver
handle
to completely remove the topmost
whee l bolt and set it aside on a
clean surface
¢ fig. 180 .
.,. Screw the threaded end of the alignment pin
from the tool kit hand-tight into the empty bolt
hole¢
fig. 181.
.,. Then remove the other wheel bolts as descr ibed
above .
.,. Take
off the wheel leav ing the alignment pin in
the bolt hole ¢Q).
Putting on the compact spare wheel
.,. Lift the spare wheel and carefully slide it over
the a lignment pin to guide it in place ¢0 .
.,. Use the hexagonal socket in the screwdr iver
handle to screw in and tighten all wheel bolts
slightly.
.,. Remove the alignment pin and insert and tight­
en the remaining whee l bolt slightly like the
rest .
.,. Turn the jack handle counter-clockwise to lower
the vehicle until the jack is fully released.
.,. Use the wheel bolt wrench to t ighten all wheel
bolts firmly¢
page 243. Tighten them cross­
wise,
from one bolt to the (approx imately) op ­
pos ite one, to keep the wheel centered .
0 Note
When removing or installing the wheel, the
r im could hit the brake rotor and damage the
rotor. Work carefully and have a second per­
son help you.
@ Tips
Never use the hexagonal socket in the handle
of the screwdr iver to loosen or tighten the
wheel bolts.
- Pull the reversible blade from the screwdriv­
er before you use the hexagonal socket in
the handle to turn the wheel bolts.
Emergency assistance
-When mounting tires with unidirectional
tread design
make sure the tread pattern is
pointed the right way¢
page 245 .
-The wheel bolts shou ld be clean and easy to
t ur n. Check for dirt and corrosion on the
mating surfaces of both the wheel and the
hub. Remove all dirt from these surfaces be­
fore remounting the wheel.
Tires with unidirectional tread design
Tires with unidirectional tread design must be
mounted with their tread pattern pointed in the
right direction .
U sing a spare tire with a tread pattern
intended for use in a specific direction
When using a spare t ire with a tread pattern in­
tended for use in a specific direction, please note
the following:
- The direct ion of rotation is marked by an arrow
on the side of the tire.
- If the spare tire has to be insta lled in the incor­
rect direction, use the spare tire only tempora­
r ily since the tire w ill not be able to achieve its
optimum performance characteristics with re­
gard to aquaplaning, noise and wear .
- We recommend that you pay part icular atten­
tion to th is fact during wet weather and that
you adjust your speed to match road condi­
tions.
- Replace the flat tire with a new one and have it
installed on your veh icle as soon as possible to
restore the handling advantages of a unidirec­
tional tire.
Notes on wheel changing
Please read the information ¢ page 221 if you
are going to use a spare tire which is different
from the tires on your vehicle.
After yo u change a tire:
-Check the tire pressure on the spare immedi-
ately after installation.
