-Airbag system ----=---'---------------------------------------------
& WARNING (continued)
• To reduce the risk of injury when the airbags inflate, the driver
and passengers must always sit in an upright position, must not
lean against or place any part of their body too close to the area
where the airbags are located .
• Occupants who are unbelted, out of position or too close to the
airbag can be seriously injured by an airbag as it unfolds with
great force in the blink of an eye~ page
147.
& WARNING
A child in a rearward -facing child safety seat installed on the front
passenger seat will be seriously injured and can be killed if the
front airbag inflates -even with an Advanced Airbag System .
• The inflating airbag will hit the child safety seat or infant
carrier with great force and will smash the child safety seat and
child against the backrest, center arm rest, door or roof.
• If you must install a rearward facing child safety seat on the
front passenger seat because of exceptional circumstances and
the PASSENGER AIR BAG OFF light does not come on and stay on ,
immediately install the rear -facing child safety seat in a rear
seating position and have the airbag system inspected by your
Audi dealer .
& WARNING
Objects between you and the airbag will increase the risk of injury
in a crash by interfering with the way the airbag unfolds or by
being pushed into you as the airbag inflates .
• Never hold things in your hands or on your lap when the vehicle
is in use .
• Never transport items on or in the area of the front passenger
seat . Objects could move into the area of the front airbags during
& WARNING (continued)
braking or other sudden maneuver and become dangerous projec­
tiles that can cause serious personal injury if the airbags inflate.
• Never place or attach accessories or other objects (such as cup
holders, telephone brackets, large , heavy or bulky objects) on the
doors , over or near the area marked "AIRBAG" on the steering
wheel, instrument panel , seat backrests or between those areas
and yourself . These objects could cause injury in a crash, espe­
cially when the airbags inflate .
• Never recline the front passenger's seat to transport objects .
Items can also move into the area of the side airbag or the front
airbag during braking or in a sudden maneuver . Objects near the
airbags can become projectiles and cause injury, particularly when
the seat is reclined.
& WARNING
The fine dust created when airbags deploy can cause breathing
problems for people with a history of asthma or other breathing
conditions.
• To reduce the risk of breathing problems , those with asthma or
other respiratory conditions should get fresh air right away by
getting out of the vehicle or opening windows or doors .
• If you are in a collision in which airbags deploy, wash your
hands and face with mild soap and water before eating .
• Be careful not to get the dust into your eyes, or into any cuts or
scratches .
• If the residue should get into your eyes , flush them with
water. •

passenger seat, or
• the weight registered on the front passenger seat is equal to or
less than the combined weight of a typical 1 year -old restrained in
one of the rear-facing or forward-facing infant restraints listed in Federal Motor Vehicle Safety Standard 208 with which the Advanced
Airbag Sys tem in your vehicle was certified.
If the front passenger seat is not occupied, the front airbag wi ll not

on the front seat -some important things to know" and=>
page 168,
"Chi ld Safety" .
If the PA SS ENG ER A IR BAG OFF l ight com es on when one of the
conditions listed above is met, be sure to check the light regularly
to make certain that the
P ASSE NG ER AIR BAG OFF light stays on
continuously whenever the ignition is on. If the
PASSENGER AIR
B AG OFF
light does not appear and not stay on all the time, stop as
soon as it is safe to do so and
• reactivate the system by turning the ignition off and then turning
it on again;
• remove and re install the child restraint. Make sure that the chi ld
restraint is properly insta lled and that the safety belt for the front
passenger seat has been correct ly routed around the ch ild restraint
as described in the child restraint manufacturer's instructions;
• make sure that the convertible locking feature on the safety belt
for the front passenger seat has been activated and that the safety
belt has been pulled tight. The be lt must not be loose or have loops
of slack so that the sensor below the safety belt latch on the seat can
do its job=>
page 177 .
• make sure that things that may increase the weight of the child
and child safety seat are not being t ransported on the front
passenger seat;
• make sure that the safety belt tension sensor is no t blocked.
Shake the safety belt latch on the front passenger seat back and
forth;
• If a strap or tether is being used to tie the chi ld safety seat to the
front passenger seat, make sure that it is no t so tigh t that it causes
the weight -sensing mat to measure more weight than is actually on
t he seat .
If the PA SSEN GER AIR BAG OFF lig ht still doe s no t c om e on and does
not stay on continuously (when the ignition is switched on),
• t ake the child restraint off the front passenger seat and install it
proper ly at one of the rear seat positions. Have the airbag system
inspected by your Audi dealer immediately.
• move the child to a rear seat position and make sure that the
child is properly restrained in a child restra int that is appropriate for
its size and age .
T he
PASSENGER AIR BAG OFF light shou ld NOT come on when the
ignition is on and an adult is sitting in a proper seating position on

Notice about data recorded by
vehicle control modules
Your vehicle is not equipped with an Event Data Recorder (EDR),
installed by some manufacturers for the express purpose of
capturing data for retrieval after an accident or crash event . EDR's
are sometimes called "crash recorders".
Some state laws restrict the retrieval or downloading of data stored
by EDR's that were installed in a vehicle for the express purpose of
retrieving data after an accident or crash event w ithout the owner's
consent.
Although your vehicle is not equipped with an EDR, it is equipped
with a number of electronic control modules for various vehicle systems such as, for example, engine function, emission control, as
well as for the airbags and safety belts.
These electronic control modules also record vehic le-related data
during norma l vehicle opera tion for diagnostic and repair purposes .
The recording capacity of the electronic control modules is limited
to data (no sound is recorded) and only a small amount of data is
actually 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 vehic le speed, direction,
braking as well as restraint system use and performance in the
even t of a crash or other condition . Stored data can only be read and
downloaded with special equipment.
Electronic Stabilization Program (ESP)
Genel'61
The Electronic Stability Program increases driving
sta bility.
Fig . 142 Cente r
cons ole with ESP
sw itch
With ESP, control over the veh icle is increased in situations when
the vehicle is close to the limits of grip, such as during acce leration
and in curves. ESP reduces the risk of skidding a nd improves vehicle
stability under all road conditions . It operates at all speeds .
The Anti-Lock Brake System (ABS), E lec tronic Differentia l Lock (EDS)
and Anti-Slip Regulation System (ASR) are integrated in the Elec­
tronic Stability Program .
H ow ESP work s
The ESP control unit processes the following data from high-sensi ­
tive sensors: the rotational speed of the vehicle about its vertica l
axis, fore -and -aft and lateral acceleration forces, brake pressure and
steering angle.
Using steering ang le and vehicle speed, the direction the driver
wishes to travel is determined and continuously compared with
actual vehicle behavior . If the two do not match, for example when

After 15 cycles (deploy and retract), manual operation is suspended
fo r up t o 2.5 minutes . Above 75 mph (120 km/h), operation swi tches
to automatic mode .
& WARNING
Driving at higher speeds witho ut the re ar spoiler deployed can
impair handling characteri stics, making the vehicle harder to
c ontrol.
• Always make sure that the spoiler i s deployed when driving at
speeds over 85 mph (140 k m/h). If the rear spoiler warning /ind i­
c ator light in the in strument clu ster come s on , the rear spoiler
may not have deployed .
• Never drive at speed s higher than 85 mph (140 km /h ) if the
spoiler is not deployed . Have the spoiler inspe cted as soon as
po ssible by an authorized Audi dealer or qualified workshop.
• Always obey speed limits and other traff ic law s.
& WARNING
Improper operation of the rear spoiler can cause crushing injuries.
• Always make su re that nobody , especially children , is in the
way when the rear spoiler is deployed or retracted.
0 Note
Never push the vehicle or a pply force to the rear spoi ler -it cou ld be
damaged .
[ i ] Tips
Clean the spoi ler compartment every 2 to 3 months . The spoiler
compa rtment must always be free of ice, snow, leaves or other
debris. •
Braking
General "nformation
What aff ects braking effi cie ncy?
Operating condition s and driving habits
The brakes on today's automob iles a re sti ll sub ject to wea r,
depending large ly o n operati ng co nditions and driving habits~&.
On vehicles which are driven mostly in stop -and -go city traffic or
whic h are driven hard, the brake pa ds shou ld be checked by your
authorized Audi dea ler more often than specified in the
Mainte ­
nance
& Warranty booklet.
On steep slopes, you should use the braking effect of the en gine.
Th is way, you prevent u nneces sary wea r on the brake syste m. If you
must use your brakes, do not ho ld the brakes down continuous ly.
P ump the brakes at interva ls.
Moisture or road salt
U nde r certain co nditi ons, for example, when driving th rough water
or v ery heavy rain, or eve n after washing your vehicle, the braking
effec t can be red uced d ue to mo isture (o r in freezing c onditions ice)
o n the brake pads . A few cautious brake appl ica tions should dry off
the brake pads or remove any ice coat ings.
T he effe ctiveness of the brakes can be reduced when the ve hicle is
driven on a sa lt -covered road and the brakes are not used. Li kewise,
you clean off accu mulated sa lt co atin g fr om bra ke discs a nd pads
with a few cautious applications of the brake~&.
Corrosion
There may be a tendency for dirt to build up on the brake pads and
corr osi on to for m on the d iscs if the ca r is no t driven regu lar ly or
only for short trips with litt le use of the brakes .
I f the b ra kes a re not used frequently, or if co rros ion ha s formed on
the d iscs, it is adv isable to clean off the pads a nd discs by braking
firm ly a few times from a moderately high speed~& . .,_

Faults in the brake syst em
If you shou ld notice a sudden i ncrease in brake pedal travel, then
one of the two brake circuits may have failed=>
& -
Low brake fluid level
Ma lfunctions can occur in the brake system if the brake fluid leve l is
t oo low. The brake fluid level is moni tored e lect ronica lly .
Brake pow er assist unit
The brake p ow er assist un it increas es th e pressure that you
generate with the brake peda l. It works only when the engine is
running.
& WARNING
• You should perform braking maneuver s for the purpose of
c leaning the brake system only if road conditions permit . Other
road users must not be put at ri sk -you may cause an accident!
• Before des cending a steep grade , redu ce speed and sh ift trans­
mi ssion into a lower gear or lower driving position . Do not ride the
br akes 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 resting your foot on the pedal when
you do not intend to brake . Thi s may cause the brakes to overheat,
premature we ar and increased stopping distan ce .
• Under certain cl imatic and operating condit ions such as
pas sing through water , driv ing in heavy rain or after washing the
vehicle, the effectiveness of the brake s can be reduced . In winter ,
ice can ac cumulate on the brake pads , linings , discs and drums .
Cautiously apply brakes for a te st. Brakes will dry and ice coatings
will be cleaned off after a few cautious brake appli cations .
• Driving for an extended period of time on salt -covered road s
without using your brakes can also affect brak ing effic iency . Clean
off accumulated salt coating from brake discs and pads with a few
c autiou s brake applications .

& W
ARNING (continued )
• If you damage the front spo iler , or if you install a different
s poiler , be sure the air flow to the front brakes is not obstructed.
Otherwise the brake system could overheat redu cing the effective­
ness of the entire br ake system.
• Failure of one brake circuit will impair the braking capability
resulting in an increa sed stopping distance. Avoid driving the
vehicle and have it towed to the nearest Audi dealer or qualified
workshop.
• Never let the veh icle roll to a stop with the engine shut off .
• If the b rake booster is not working , for e xample when towing
your vehicle, or because the brake booster has somehow been
damaged , the brake pedal must be pre ssed considerably harder to
make up for the lack of booster assistance . •
Anti- lock brake system (ABS)
ABS p revents the wheel s from loc king unde r br ak ing.
The anti -lock brake sys te m (ABS) makes a major contri but ion to
i ncreasing act ive d riv in g sa fety . You should not expect that brakin g
distances wi ll be
shortened unde r all c ircums tances wi th ABS.
B rak in g distance may even become somewhat
longer , for e xa m ple ,
on gravel or in new snow on s lippery ground, even if you are driving
carefully and slowly.

Natural leather
Aud i m akes gre at effo rts to maint ain th e pr oper ties,
n atur al look and feel of interi or le ather.
Gener al
We offe r many d ifferent types of leathe r on our vehicles. Mo st are
different types of nappa leather , which has a smooth surface and
comes in various co lo rs.
The intensity o f the color determ ines the visua l characteristics and
appearance. If the surface of the leather has a typical natura l look,
then t he leather is a nappa lea ther that has bee n left in a re latively
natura l condition. This leather offers particu lar ly good comfort and
b reathes well. Fi ne veins, closed g ra ins, insect bites, skin folds, an d
subtle variations in co lor remain visib le. These characteristics
dem onstrate that the mater ial is natural.
Natura l nappa leather is not covered by a co lor finish . It is therefore
more sensitive to soil ing and wear, which is something you need to
consider if chi ldren, animals or other fac tors might prove to be
particularly hard on the leather.
By con trast, leather types that are covered by a colo red fin ish layer
are more durable. This has a positive effect on the leather's resis ­
tance to wea r and s oiling i n daily use . On the ot her hand, the typical
characteristics of natura l leather are barely or not apparent .
However, this does not mean that the leather itself is of inferior
qua lity .
Care and handling
Because of the exclusive nature of the types of leather that Audi
u ses and thei r unique p rope rties (suc h as sens it ivity to oi ls, g rease,
soi ling, etc .), you wi ll need to be somewhat careful w ith these
leathers, and a certain type of care is required. For example, dark .,.
