t he 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.

Braking
New brake pads
During the first 250 miles (400 km), new
b rake pads do not possess their full braking
effect, they have to be "broken in" first. The
distance can be ten times longer in veh icles
with ceramic brakes*. You can compensate for
this slightly reduced brak ing power by push
ing harder on the brake pedal. Avoid heavy
braking loads during the break-in period.
Operating conditions and driving habits
The brakes on today's automobi les are sti ll
subject to wear, depending largely on operat
ing conditions and dr iv ing habits
c:> & . On ve
hicles that are either driven mostly in stop
and-go city traffic or a re driven hard, the
brake pads should be checked by your author
ized Audi dealer more often than specified in
the
Warranty & Maintenan ce booklet . Failure
to have your b rake pads inspected can result
in reduced brake performance.
On steep slopes, you shou ld use the brak ing
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
va ls.
Moisture or road salt
Under ce rta in conditions, for example, when
d riving through water or very heavy rain, or
even after washing your vehicle, the braking
effect can be reduced due to moisture (or in
freezing conditions ice) on the brake pads. A
few cautious brake applicat ions should dry
off
the brake pads or remove any ice coatings.
When you are driving at higher speeds with
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 dr iven on a salt-covered
road and the brakes are not used . Likewise,
Intelligent technology 145
you clean off accumulated salt coating from
brake discs and pads with a few cautious ap
plications of the brake
c:> & .
Corrosion
The re may be a tendency for dirt to build up
on the brake pads and corros ion to form on
the discs if the car is not driven regularly or
on ly for short trips with litt le use of the
brakes.
If the brakes are not used frequently, o r if cor
rosion has formed on the discs, it is advisable
to clean
off the pads and discs by braking
firmly a few times from a moderately high
speed
c:> & .
Faults in the brake system
If you shou ld notice a sudden increase in
brake pedal travel, then one of the two brake
circuits may have fai led . Drive immediately to
the nearest qualified workshop to have the
damage repaired. Drive at reduced speed on
the way there and anticipate longer stopping
distances and higher pedal pressure c:> &,.
Low brake fluid level
Malfunctions can occur in the brake system if
the brake fluid level is too low. The brake flu id
level is monitored electronically.
Brake power assist unit
T he brake power assist unit increases the
pressure that you generate with the brake
pedal. It works only when the engine is run
ning.
Brake lining wear status
Brake lining wear may be checked by visual in
spection of t he condition of the brake pads
thro ugh the openings in the wheel. If neces
sary, the whee l may be removed for this in
spection
c:> page 206 .
A WARNING
--You should perform braking maneuvers
for the purpose of cleaning the brake
system only if road conditions permit.

146 Intellig ent technolog y
Other road users must not be put at risk -
yo u may cause an acc ident!
- Before descending a steep grade, reduce
speed and shift transmission into a lower
gear or lower driving position . Do not
ride the brakes or ho ld the pedal down
too long or too often . This cou ld cause
the brakes to get hot and d iminish brak
ing 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 b rakes to
overheat, premature wea r and inc reased
stopp ing distance.
- Under certain climat ic and operating
condit ions such as passing through wa
ter, driving in heavy ra in or after wash ing
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 w ill be cleaned off after a few cau
t ious brake applications .
- Driv ing for an extended period of time on
salt-covered roads w ithout us ing your
brakes can also affect braking efficiency .
Clean off accumulated salt coating from
brake discs and pads w ith a few cautious
brake applicat ions.
- If you damage the front spoiler, or if you
ins tall a different spoiler, be su re the air
flow to the front brakes is not obstruct
ed. Otherwise the brake system co uld
overheat red ucing the effectiveness of
the ent ire brake system.
- Failure of one brake circuit will impair
braking capab ility, resulting in increased
stopp ing distance. Avoid driv ing the vehi
cle and have it towed to the nearest au
thorized Aud i dealer or qualified work
shop .
- Never let the vehicle roll to a stop w ith
the engine shut off .
- If the brake booster is not working, for
example when tow ing your vehicle, or
because the b rake booste r 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 s teer .
Power steering helps the driv er steer the vehi
cle with litt le physica l effort.
If the engine is not running, the power steer
ing system is also not working . In this case ,
you wi ll find it extremely d ifficu lt to turn the
steering wheel.
If you turn the steering fully to the left or
rig ht when the vehicle is stationary, you p lace
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 id le speed.
(D Note
Do not hold the steering t urned fu lly to
the left or r ight for more than 10 seconds
when the engine is running . There is a r isk
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 ab le
to steer the vehicle. However, you will re
quire more effort to do so .
- If the powe r stee ring system has a leak
or is defect ive , you should immediately
contact a qualified wor kshop .
- The power steer ing system req uires a
special hydraulic fl uid. The power steer
ing fluid reservoir is located in t he en
gine comp artment. The co rrect hydrauli c
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.

150 Driving and en vironm ent
Driving and
environment
Break-in period
A new vehicle must be broken in, and the break-in per iod should be 1,500 miles (2,500
km) . Do not use full acceleration for the first
600 miles (1,000 km) and do not exceed the
maximum eng ine speed of 6,000 rpm You
m ust also not use fu ll acce lerat ion between
600 and 1,200 m iles ( 1,000 to 2,000 km).
Fr om 1,200 to 1 ,500 mi les (2,000 to 2,500
km), you can gradua lly increase maxim um en
gine speed to 8,250 rpm for brief periods.
During the first ho urs of operation, there is
g reater friction in the engine and the trans
mission than later when a ll the moving parts
have broken in.
The way yo u drive duri ng the first 1 ,500 miles
(2,500 km) affects engine quality. If you drive
at moderate engine speeds thereafter, partic
u lar ly when the engine is cold, yo u reduce en
gine wear and increase the potential mileage
of the engine.
Do not drive at RPMs that are too low. Shift
down when the engine is no longer running
"smoothly". Extreme ly high RPMs are gov
erned automa tically.
Driving through water
on roads
Note the following to avoid vehicle damage
when dr iving t hrough water, for example on
flooded roads:
- The water must not be any higher than the
bottom of the vehicle body .
- Do not drive faster than wa lking speed .
.&_ WARNING
After driving through water, mud, slush,
etc., the brakes may be slow to take effect
because of wet b rake roto rs and pads. Dry
t he brakes fi rst by bra king carefully to re
sto re the full braking effect .
-
(D Note
Vehicle components such as the eng ine,
transmission, suspension or e lectrical sys
tem can be severe ly damaged by dr iv ing
through water .
@ Tips
-Check the depth of the water before d riv
ing through it.
- Do not stop the vehicle, drive in reverse
or switch the engine off when driving
through water.
- Keep in mind that oncoming vehicles
may create waves that raise the water
level and make it too deep for your vehi
cle to drive through safely .
- Avo id driving through salt water because
it can cause corros ion.
Catalytic converter
You must use lead-free gasoline in your veh i
cle, otherwise you will destroy the ca talyt ic
converter .
Never run the fuel tank completely dry; their
regular fue l supply could cause misfires . This
allows unburned fue l into the exhaus t system,
poss ibly resulting in overheating and damage
to the catalytic converter .
.&_ WARNING ,-
-Do not park or operate the vehicle in
a reas where the hot exha ust system may
come in co nta ct with dry g rass, brush,
fue l spills or o ther material which can
cause a fire.
- Do not app ly addition al under coating or
r u stproofing on or nea r the exhaust
manifold, exhaust pipes, catalytic con
verter or heat shields . Dur ing driving, the
substance used for undercoating could
overheat and cause a fire.
(D Note
To ensure efficient o peration of the Emis
s ion Control System :

-Have you r vehicle maintained properly
and in accordance with the service rec
ommendat ions in your Warranty
& Main
tenance booklet.
- Lack of proper maintenance as well as
improper use of the vehicle will impair
the function of the Emission Control Sys
tem and could lead to damage.
Sporty driving
Warming up and cooling down
By carefully warming up and cooling down
your vehicle, you can he lp ensure that it is not
overstressed unnecessarily during sporty driv
ing.
When warming up, the vehicle is driven at a maximum engine speed of 6000 RPM
(Vl0 engine) or 7000 RPM (V8 engine) in or
der to raise the engine oil temperature to a minimum of 140 °F (60 °(). The tires also on
ly reach their full road holding capability once
they have warmed up.
The cooling fan can continue to run in your ve hicle after the engine is switched
off. H owev
er, driving the vehicle to cool it down is part ic
ularly important. During sporty driving, the
engine and brakes, the exhaust system, and
the t ransm ission all become extreme ly hot.
Before you park the vehicle, you shou ld d rive
it for a few mi les/kilometers at light load in
the low rpm range to allow it to coo l down .
Driving on a track
Before you take your vehicle out on a track,
ensure that it is in perfect condition. For ex
ample, you should check the tire tread and the brake pads . It is best to increase t ire pressure
by about 0 .3 bar .
When driving on a track, oil consumption may be somewhat higher than in "normal" opera
tion
¢ page 17 4 .
You shou ld definitely inspect your vehicle af
ter subjecting it to severe condit ions. Are the
brake pads OK? Is there anything unusual
Dri vin g and en vironm ent 151
about the ti res, including the inner and outer
sidewa lls (e.g . tread, blistering)? Are the air
intakes free of leaves and tire dust? Is the o il
l evel OK?
Your authorized Audi dea ler or qua lified work
shop will be happy to undertake an inspection
before and after use on the race track.
_& WARNING
-
Some race tracks (e.g. steeply banked
turns) may affect the response of the ESC.
(D Tips
- Review the track requirements and con
ditions before you start driving.
- When driven on a race track, all vehicle
parts are severe ly stressed. This can re
sult in increased wear.
Operation and maintenance
Fuel economy, env ironmenta l impact, and
wear on your eng ine, brakes and tires la rgely
depend on three facto rs:
- your personal driving style
- operating conditions
- technical limitations
By havi ng your ve hicle reg ularly se rviced by an
a uthorized Aud i dea le r helps to ens ure that i t
runs properly and economica lly. The condition
of your vehicle not only affects its safety and
ability to ho ld its va lue, it a lso affects
f u el
consumption .
The amount of oi l used is re lated to engine
load and speed .
It is normal for the oil consump tion of a new
engine to reach its lowest value after a certa in
mileage has been driven.
You must drive your veh icle about 3,000 m iles
(5,000 kilometers) before yo u can p rope rly
assess oil consumpt io n.
Th is also app lies to fue l consumption and en-
gine o utp ut.

154 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 156. Use
a
shampoo only for very 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.
- Fold the exterior mirrors flat - there is a
risk of damaging the exterior mirrors.
Power folding exterior mirrors must not
be folded in or out by hand. Use the pow
er function!
- Do not wash the vehicle in direct sun
light. You may damage the paint.
- Do not use sponges designed to remove
insects, rough kitchen sponges, or simi
lar products. You risk damaging the
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.
@) For the sake of the environment
Wash your vehicle only at specially de
signed facilities. They can prevent any dirty
water contaminated by oil from entering
the waste water. In certain areas washing
a car outside of such facilities is not per mitted.

178 Checking and filling
Brake fluid
Hove the brake fluid changed by an experi
enced technician .
Brake fluid absorbs moisture from the air. If
the water content in the brake fluid is too
h igh, corrosion in the brake system may result
after a per iod of t ime . The bo iling po int of the
brake fluid w ill also decrease considerably and
decrease b rak ing performance .
Therefore, the brake f lu id must be changed
every two years . Always use new brake fluid
which conforms to Federal Motor Vehicle
Standard "FMVSS 1 16 DOT 4".
Brake fl uid is rep laced according to the Audi
maintenance service schedule. Your author
ized Audi dealer is equipped with the necessa
ry special tools and replacement parts, has
the necessary expe rtise, and can d ispose of
the used fluid .
.&_ WARNING
- Brake fluid is po iso nous. It mus t be s to r
ed on ly in the closed orig inal con taine r
o ut o f th e reac h of children!
- Br ake f ailure can resul t from old o r in ap
propr iate brake fluid. Observe these pre
caut ions:
- Use o nly brake fluid that meets SAE
specification
J 1703 and co nfo rms to
Federal Motor Vehicle Sta ndard 116 .
A lways check wi th you r a uthori zed Aud i
dealer to m ake sur e you are u sing the
correct br ake f luid. The co rrec t type of
b rake fluid is a lso indica ted on the
b rake fluid reservoir .
- The brake flui d must be new. Heavy use
of the brakes can ca use a vapor loc k if
the brake fl uid is left in t he system too
l o ng. This can ser io usly affect the effi
ciency of the brakes as well as yo ur
safety. This could result in an acc ident.
Brake fluid will damage the paint of your
veh icle.
{® For the sake of the environment
Because of the p rob lem of proper disposal
of brake fluid as well as the spec ia l too ls
required and the necessary expertise, we
recommend that you have the brake flu id
cha nged by yo ur autho rized Aud i dea le r.
Battery
General information
All work on the ba ttery requires technical
knowledge.
The battery is located be hind the cov er in the
l u ggage compa rtment. Remove the cover by
pu shing i t to the left an d lift ing it o ut.
The battery is practically maintenance-free
and is checked as pa rt of your ve hicle's main
tenance se rv ices .
You are we ll advised to replace a battery that
i s older tha n 5 yea rs .
Disconnecting the battery terminals
Some vehicle f unctions (power window reg u
l ators, for example) are lost if the battery te r
mina ls are disconnected. T hese functions have
to be relearned after the battery termina ls are
co nn ected aga in . T o p revent th is, t he battery
shou ld only be disconnected from the ve hicle
elect ric al sy stem w hen abso lutely ne cessary
f or rep airs.
Vehicles not driven for long periods
The battery becomes d ischarged due to quies
cent current consume rs even when the vehicle
is not used. With extended pe riods of non-use
in t he
cold season, yo u should have t he ve hi
cle b attery removed by an autho riz ed Aud i
dealer or qualif ied workshop and stored in an
frost-free place. T his prevents the battery
from "freezing" and thereby being destroyed.
D uring the
warme r seasons it is enough to
disco nnect the battery negat ive terminal. Oc-
cas ionally charge a disconnected battery.
