A 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
slightly reduced braking force by pressing
firmly on the brake pedal. Avoid heavy brak­
ing during the break-in period.
- Only 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 ­
hicle 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 -
162
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
pedal 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 nec­
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 than normal.
- If you retrofit your vehicle with a front spoil­
er, wheel covers or similar items, make su re
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 .
The 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. .,.

Intelligent Technology
All wheel drive (quattro)
Applies to vehicles: with all wheel drive
In all wheel drive, all four wheels ore powered.
General information
In all wheel dr ive, the driving power is div ided be­
tween all fou r wheels . This happens automatical­
ly depending on yo ur driving behavior as well as
the current road conditions . A lso see
c> page 159, Electronic stabilization control
(ESC).
The all whee l drive concept is designed for high
engine power. Yo ur vehicle is exceptionally pow­
erfu l and has excellent driving characteristics
both under normal driving conditions and on
snow and ice. Always read and follow safety pre­
cautions
c> ,&. .
Winter tires
By using all wheel drive, your vehicle has good
forward motion with standard tires in winter con­
ditions. However, in winter we recommend using
winter or all season tires on
all four wheels, be­
cause this will improve the
broking effect.
Snow chains
If there are snow chain laws, snow chains must
also be used on veh icles w ith all wheel dr ive
c> page 269, Snow chains.
Replacing tires
For vehicles with a ll wheel d rive, only wheels with
the same rolling circumference should be used .
Avoid wheels with different tread depths
c> poge 260.
Offroad vehicle?
Your Audi is not an offroad vehicle -there is not
enough ground clearance. For this reason, avoid
difficu lt terrain . Also see<=)
page 302.
A WARNING
--Also, in veh icles with all whee l drive, adapt
your driving style to the current road and
traffic cond itions. Do not let the increased
safety prov ided tempt you into taking r isks.

Airbag syste m
-An Advanced Airbag with gas generator for the
driver inside the steering wheel hub .
- An Advanced Airbag with gas generator ins ide
the instr ument pane l for the front passenger.
- A capacitive passenger detect io n system unde r­
neath the front passenger seat cover . This sys­
tem measures the electrical capacitance of the person in th e seat. The information registered
is sent continuously to the electron ic control
unit to regula te deployment of the front Ad­
vanced Airbag on the passenger s ide .
- An airbag monitoring system and indicator
light in the instrument cluster
¢ page 196.
-A sensor in each front seat registers the dis­
tance between the respective seat and the
steering wheel or instrument panel. The infor­
mation reg istered is sent continuously to the
electronic control un it to regulate deployment
of the fro nt Advanced A irbags.
- The
PASSENGER AIR BA G OFF light comes on
and stays on in the center of the instrument
panel ¢
page 236 and tells you when the front
Advanced Airbag on the p assenge r side has
been turned off .
- A sensor in the safety belt la tch for the driver
and for the front seat passenger that senses
whethe r that safety belt is latched or not and
transmits this information to the electronic contro l unit.
.&_ WARNING
Damage to the front passenger seat can pre­
vent the front airbag from working properly.
- Improper repa ir or disassemb ly of the front
passenger and driver seat w ill prevent the
Advanced Airbag System from functioning properly .
- Repairs to the front passenger seat must be
performed by qua lified and prope rly trained
workshop personnel.
- Never remove the front passenger or dr iver
seat from the vehicle.
- Never remove the upho lstery from the front
passenger seat.
- Never disassemble or remove parts from the
seat or disconnect wires from it.
192
- Never carry sharp objects in your pockets or
put them on the seat. The capacit ive pas­
senger detection mat in the front passenger
seat will not function properly if it is punc­
tured .
- Never carry things on your lap or carry ob­
jects on the front passenger seat . Such ob­
jects ca n influence the capacitance regis­
tered by the capacitive passenger detection
sys tem, so tha t incorrect informat io n is pro­
vided to the a irb ag cont rol unit.
- Never store items under the front passenger
se at. Parts of the Advanced Airbag System
un der the passenger seat could be dam­
aged, p reventing them and the airbag sys ­
tem from wor king p roper ly .
- Never p lace seat covers or replacement up­
holstery that have not been specifically ap­
proved by Audi on the front seats .
- Seat covers can prevent the Advanced A ir­
bag System from recognizing chi ld re­
straints or occupants on the front passenger
seat and prevent the side airbag in the seat
backrest from deploying properly.
- If a seat heater has been retrofitted or oth­
erwise added to the front passenger seat,
never install any child restra int system on
this seat.
- Never use cushions, p illows, blankets, or
sim ila r items o n the front passenger seat .
The additional layers prevent the capacit ive
passenge r detection sys tem from accurately
measuring the capacitance of the child safe­
ty seat and/or the person on the sea t and
t hus keep the Advanced A irbag System from
wo rking properly.
- Never p lace or use any e lectr ic al device
(such as a lap top, CD player, e lectronic
games device , power inve rter or seat heater
for child seats) on the front passenger seat if the device is connected to the 12 -volt
socket or the cigarette lighte r socket. Such
dev ices can influence the capac itance regis­
tered by the capaci tive passenger detection
system, so that incorrect informat io n is pro-
vided to the airbag cont rol unit.
