as a pulsing motion of the brake pedal, ac
companied by some noises. In order for ABS
to be able to operate optimally in th is range,
you must keep the brake pedal depressed -
never "pump the brakes" . You should not ex
pect that braking d istances w ill be
shortened
under all circumstances with ABS . Braking dis
tance may even be slightly
longer, for exam
p le on gravel or wi th fresh snow on a slippery
surface .
If a sign ificant
speed differential between the
d rive wheels on one axle is determined (for
examp le, on a su rface that is s lippery
on one
side),
the EDS brakes the spinn ing whee l and
transfers power to the other drive whee ls.
This is done up to a speed of about 60 mph (100 km/h) . Noises from the brake system
signal that whee l spin is being controlled.
I f one whee l spins when starting from a com
p lete stop because o f a different grip (for ex
ample , one wheel o n ice), keep your foot
hard
on the accelerator until the veh icle starts to
move.
If the wheels spin , ASR wi ll automatically re
duce engine torque and match power to road
surface conditions .
Switching on Sport mod e
In specific driving situations (e.g. Launch Con
trol), you swi tch ASR and ESP to Sport mode
by pressing the
[!I button once . The indicator

appears . "Slip" is matched
to the speed. You should do this only if your
driving skill and traffic cond it ions permit .
Switching ASR /ESP off
In certain sit uations (e .g . in deep snow, on a
l oose surface, o r when rocking the vehicle
free), switch ASR and ESP off by pressing the
[ill button for more than 3 seconds. The ind ica
tor light
I) illuminates and ES P sw itc hed off -

should do th is only if your driving skill and
traffic cond itions pe rmit .
Int ellig ent technolog y 151
Switching ASR /ESP on
Activate ASR/ ESP by p ressing the [!I button
again. The message
ESP on appears in the d is
play briefly.
Brake overheating
So that the disc b rake on a b raked wheel does
not overheat, the EDS switches off automati
ca lly if there is un usua lly severe loa ding at
th is wheel. The vehicle is st ill drivable and has
the same properties as a vehicle wit hout EDS .
As soon as the brake has cooled down, EDS
swi tches on aga in automatically.
A WARNING
- Even ESP, ABS, EDS and ASR cannot over
come the laws of physics . You should
keep this in m ind in particular on an icy
or wet road. If the systems intervene,
you shou ld adjust your speed immediate
ly to road and traff ic conditions . Do not
be tempted by the increased safety pro
vided to take risks -you risk having an
accident.
- Please keep in mind that the r isk of an
accident is i ncreased by driving too fast,
pa rti cularly in corners and on icy or wet
ro ads, and by drivi ng too close to the ve
hicle ahead . Even ES P, ABS, E DS and ASR
cannot eliminate the increased risk of
having an accident.
-Apply the throttle ca re fully when accel
erating on a consistently s lippery sur
face, e.g. on ice and snow . The drive
wheels can spin in spite of the EDS and thereby affect vehicle stability -you risk
having an accident .
- Please note that when ASR or ESP/ASR is
deactivated, the drive wheels can spin on
icy and slippery roads and the veh icle can
break away -the re is a risk of skidd ing!

Braking
New brake pads
During the firs t 250 miles (4 00 km), new
b rake pads do not possess their f ull braking
effect, they have to be "broken in" first. The
d istance can be ten times longer in ve hicles
with ceramic brakes *. Yo u can compensate f or
this slightly reduced b rak ing power by push
in g harder on the b rake pedal. Avoid heavy
br ak ing loads during the b reak -in period.
Operating conditions and driving habits
The brakes on today's automob iles are st ill
subject to wear, depending largely on operat
ing conditi ons and dr iv ing habits
c:> & . On ve
hi cles that are either driven mostly in stop

154 Intelligent technology
Other road users must not be put at risk -
you may cause an accident!
- Before descending a steep grade, reduce
speed and shift transmission into a lower
gear or lower driving position . Do not
ride the brakes or hold the pedal down
too long or too often. This could cause
the brakes to get hot and diminish brak ing efficiency .
- Do not "ride the brakes" by resting your
foot on the pedal when you do not intend
to brake . This may cause the brakes to
overheat, premature wear and increased
stopping distance.
- Under certain climatic and operating
conditions such as passing through wa
ter, driving in heavy rain or after washing
the vehicle, the effectiveness of the
brakes can be reduced. In winter, ice can
accumulate on the brake pads, linings,
discs and drums. Cautiously apply brakes
for a test . Brakes will dry and ice coat
ings will be cleaned off after a few cau
tious brake applications .
- Driving for an extended period of time on
salt-covered roads without using your
brakes can also affect braking efficiency .
Clean off accumulated salt coating from
brake discs and pads with a few cautious
brake applications.
- If you damage the front spoiler, or if you
install a different spoiler, be sure the air
flow to the front brakes is not obstruct
ed. Otherwise the brake system could
overheat reducing the effectiveness of
the entire brake system.
- Failure of one brake circuit will impair
braking capability, resulting in increased
stopping distance. Avoid driving the vehi
cle and have it towed to the nearest au
thorized Audi dealer or qualified work
shop.
- Never let the vehicle roll to a stop with
the engine shut off .
- If the brake booster is not working, for
example when towing your vehicle, or because the brake booster has somehow
been damaged, the brake pedal must be pressed considerably harder to make up
for the lack of booster assistance.
Power steering
When the engine is running , power steering
makes i t easier for the driver to steer.
Power steering helps the driver steer the vehi
cle with little physical effort.
If the engine is not running, the power steer
ing system is also not working . In this case ,
you will find it extremely difficult to turn the
steering wheel.
If you turn the steering fully to the left or
right when the vehicle is stationary, you place
a very heavy load on the power steering sys
tem. Turning the steering wheel fully to the left or right will cause noise in the system. It
also reduces engine idle speed.
(D Note
Do not hold the steering turned fully to
the left or right for more than 10 seconds
when the engine is running . There is a risk
of damage to the power steering system .
(D Tips
-In the event of a power steering system
failure, or if the engine is not running
(while being towed), you will still be able
to steer the vehicle. However, you will re
quire more effort to do so .
- If the power steering system has a leak
or is defective, you should immediately
contact a qualified workshop .
- The power steering system requires a
special hydraulic fluid. The power steer
ing fluid reservoir is located in the en
gine compartment. The correct hydraulic
fluid level is important for proper opera
tion of the power steering system. The
power steering fluid level is checked ac
cording to the Audi maintenance service
schedule.
Driving with your
quattro ®
With all-wheel drive, all four wheels are driv
en .
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
t::;> page 150.
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 -sea
son t ires) for improved driveability and brak
ing: these tires must be mounted on
all four
wheels.
Snow chains
Where snow chains are mandatory on certain
roads, th is normally also applies to vehicles
with all-wheel drive
Q page 204 , Snow
chains.
Replacing wheels/tires
Only the wheel/tire sizes specified by the
manufacturer may be used on vehicles with
all-wheel drive
<=> page 199.
A 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 a ll-wheel drive is very effect ive,
always remember that braking capacity
is limited by tire traction. You should
therefore not drive at excessive speeds
on icy or slippery road surfaces.
- On wet road surfaces, be careful not to
drive too fast because the front wheels
cou ld beg in to slide on top of the water
(aquaplaning). If this should occur, you
will have no warning from a sudden in
crease in engine speed as with a front-

Energy management
Starting ability is optimized
Energy management controls the distribution
of electrical energy and thus optimizes the
availability of electrical energy for starting the engine.
If a vehicle with a conventional energy system
is not driven for a long per iod of time, the bat
tery is discharged by idling current consumers
(e .g. immobi lizer). In certain circumstances it
can resu lt in the re being insufficient energy
available to start the engine.
Intelligent energy management in your vehi
cle handles the distribution of e lectr ical ener
gy. Starting ability is markedly improved and
the life of the battery is extended .
Basically, energy management consists of
battery diagnosis , idling current manage
ment
and dynamic energy management .
Battery diagnosis
Battery diagnosis continuously determines
the state of the battery. Sensors determine
battery voltage, battery current and battery
temperature . This determines the current
state of charge and the power of the battery.
Idling current management
Idling current management reduces energy
consumption while the vehicle is standing.
With the ign ition switched off, it controls the
energy supply to the various electrical compo
nents. Data from battery diagnosis is consid
ered.
Depending on the battery's state of charge,
individual cons umers are gradually turned off
to prevent excessive discharge of the battery
and thus maintain starting capability. .,..

162 Cleaning and protection
Hand washing
When washing your vehicle by hand, first soft
en the dirt with copious amounts of water and
rinse it
off as best you can.
Then clean the vehicle using a soft
sponge, an
auto glove or a low-pressure wash brush.
Work from the top down to the bottom, start
ing with the convertible top
¢ page 163. Use
a
shampoo only for v ery stubborn dirt.
Rinse the sponge or auto glove thoroughly at
frequent intervals.
Clean the wheels, door sills and similar areas last. Use a separate sponge for this.
_& WARNING
-Car washes with conveyors can damage
the vehicle tires, which could cause the tire to lose pressure suddenly while driv
ing and put you at risk for an accident.
Do not use car washes with conveyors.
- Switch
off the ignition when you wash
your vehicle to avoid an accident.
- Protect your hands and arms from sharp
metal edges when you clean the under
body, the inside of the wheel wells or the
wheel covers to avoid cutting yourself.
- When washing your vehicle in the winter :
Moisture and ice in the brake system can
affect the brakes.
- Never wash tires with a jet that sprays
water in a direct stream . This could cause
invisible damage to the tires and weaken
them, even if the spray is from a relative
ly long distance and for a short time .
Damaged and weakened tires can fail
and cause accidents and personal injury.
(D Note
- Never drive your vehicle through any au
tomatic car wash that fails to provide ei
ther sufficient clearance for your vehicle
or sufficient track width for your tires. Risk of expensive damage to the vehicle's
underbody , tires, and rims!
- As described in your Warranty
& Mainte
nance booklet, damage or malfunction due to misuse of the vehicle or failure to
operate the vehicle in accordance with
the
instructions of this Owner's Manual
will not be covered under warranty.

paint surface.
- You should remove debris (such as in
sects) from the headlight lenses on a
regular basis, for example when refuel
ing your vehicle. Never clean the head
lights with a dry cloth or sponge . Use a
wet cloth or sponge .
It is best to use
soapy water.
- Never clean tires using a nozzle that
sprays water in a direct stream. Damage
can occur even with a relatively long
spraying distance and for a very short
time.
- To avoid damaging your vehicle, always
make sure that there is sufficient dis
tance between the spray head and soft materials like rubber hoses, plastic parts
and sound-deadening materials. Never
aim the spray head at the same point for
a long time. This also applies to cleaning
headlights and painted bumpers. Re
member: the closer the nozzle is to the
surface of the material, the greater the
stress on the material.
- Never clean the convertible top using a
power washer.
