There is a ma lfunction in the brake booster . The
brake booster is available, but its effectiveness is
reduced . Braking behavior may be different from
how it normally functions and the brake pedal
may vibrate.
Drive to an authorized Audi dealer or authorized
Audi Service Facility immediately to have the
malfunction corrected.
Y!., /~ Electronic Stabilization Control (ESC)
If the bJ indicator light blinks while driving, the
ESC or ASR (Anti-Slip Regulation) is actively regu­
lating.
If the
bJ indicator light turns on, the system has
switched the ESC
off. In this case, you can switch
the ignition
off and then on to sw itch the ESC on
again. The indicator light turns
off wh en th e sys­
tem is functioning fully.
If the
II indicator light turns on, ESC was
switched
off using the i.i, O FF I button
¢page 119.

General information
Breaking in
A new vehicle must be broken in for the first 1,000 mi les (1,500 km). Do not dr ive at speeds
t hat will exceed 2/3 of the max imum pe rm itted
engine speed (RPM) for the first 600 miles
(1,000 km), and avoid fu ll acceleration during
this period . You may gradually start increasing
the RPM and the speed between 600 miles
(1,000 km) and 1,000 miles (1,500 km) .
During the first hours of use, the engine has a
higher internal friction than later on when all
moving parts have settled into place with each
other.
How the vehicle is driven d uring the first 1,000
miles (1 ,500 km) a lso affects the engine quality .
Drive at moderate engine speeds after the initial
break-in per iod, part icu larly when running a cold
eng ine . Th is will reduce eng ine wear and improve
the m ileage .
Do not drive at too
low of an engine speed (RPM).
Shift down if the engine stops running "smooth­ ly". Extremely high eng ine speeds are automati­
cally reduced .
Reducing the risk of vehicle damage
@ Note
When driving on poo r roads, by cu rbs and on
s teep ramps, make su re t hat low-hang ing
compone nts such as the spo ile r and exha ust
system do not come into contact with these
or they could be damaged. This especially ap ­
plies to vehicles with low ground clearance
and veh icles that are heavily loaded.
Warming up/cooling down
Applies to: S models
By warming up/cooling down the engine carefu l­
ly, you can help red uce unnecessary stra in o n
your veh icle when driving in a sporty sty le .
64
The eng ine speed is lim ited when the engine is
cold - the full engine output is not availab le.
When the engine is at operat ing temperatu re,
the engine speed limitation moves to a h igher
RPM range. A lso, cold t ires may not have full
road gr ipping capab ilities until they have warmed
up .
Your vehicle a lso has an after-run cooling fea­
ture . However, cooling down is still important.
The eng ine and the brakes as well as the exhaust
system and the transmission become very hot
whe n driving in a spo rty style . Before you shut
t h e ve hicle off, you should cool down the vehicle
by d rivi ng a few miles at low speeds with l igh t ac ­
ce leration.
Driving through water on roads
Note the following to reduce the risk of vehicle
damag e when driving throug h water, for exampl e
on f looded roads:
- The water must not be any higher t han the bo t­
tom of the vehicle body.
- Do not dr ive faster tha n wal king speed .
& WARNING
After driving th ro ugh water or m ud, the effec ­
tiveness of the brakes may be red uce d due to
mo isture on the brake rotors and brake pads.
A few careful brake app lications shou ld dry
off the brakes and restore the full braking ef­
fect .
@ Note
-Vehicle components such as the engine,
t ransmiss ion, suspens ion or elect rical sys­
tem can be seve rely damaged by drivi ng
throug h water .
- Always switch the Start/Stop system* off
when driving through water
¢ page 70 .
(D Tips
- Determine the depth before driving throug h
water.
- Do not stop the vehicle, drive in reverse or
switch the engine off when driving through
water.

increase the risk of a collision.
(D Tips
-ABS and ASR only function correctly when
all four wheels are equipped with identical
tires. Different tire sizes can lead to a reduc­
tion in engine power.
- You may hear noises when the systems de­
scribed are working.

Brakes
New brake pads
New brake pads do not achieve their full braki ng
effec t during the first 2SO mi (400 km). They
must be "broken in" first.

a co .... N
" N .... 0 0 \,;J ' Wear Brake pad
wear depends largely on the way the
vehicle is driven and on operating conditions.
This is especially true if you are driving frequently
in the city and on curves or with a sporty driving
style.
Operating noise
Noises may occur when braking depending on the
speed, braking force and outside conditions such
as temperature and humidity.
Effect of water and road salt
In certain situations, for example after driving
through water, in heavy ra in, after overnight con­
densat ion or after washing your car, the braking
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 applica ­
tions.
At higher speeds and with the windshie ld wipers
turned on, the brake pads press against the brake rotors for a short amount of time. This action,
which is not felt by the driver, happens at regular
intervals and ensures a better reaction time for
the brakes in wet weather .
The braking effect can also be reduced if you are
driving 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
f ir st when the brakes are applied.
Corrosion
Leaving the vehicle parked for long periods of
time, low mileage and avo iding heavy brak ing
can contribute to corrosion on the brake rotors
and to d irty brake pads .
If you usually avoid heavy braking or if there is
corros ion present, occasional heavy braking at
high speeds is recommended to clean the brake
rotors and
pads¢ &..
Brake system malfunction
If you notice that the brake pedal travel has sud­
denly
increased, then a brake circuit in the dual­
circu it brake system may have malfunct ioned.
Drive to an authorized Aud i dealer or authorized
Intelligent Technology
Audi Service Facility immediately to have the
problem corrected. On the way there, drive with
reduced speed and keep in mind that you will
need a longer distance to stop and you will need
to press the brake peda l harder.
Low brake fluid level
When the brake fluid level is low, malfunctions in
the brake system may occur . The brake fluid level
is e lectronically monitored.
Brake booster
T he brake booster amplifies the press ure you ap­
ply to the brake pedal. It on ly works w hen the en­
gine is running.
A WARNING
-
-Only apply the brakes for the purpose of
cleaning the brake system when road and
traffic cond itions permit. You must not en­
danger other road users. This increases the
risk of an accident .
- Never let the vehicle roll while the engine is
stopped because this increases the risk of an
accident .
- New brake pads do not ach ieve the ir full
braking effect dur ing the first 250 m i
(400 km). They must be "broken in" first .
However, you can compensate fo r the
slightly reduced braking force by pressing
firmly on the brake pedal. Avoid heavy b rak­
ing during the break -in period.
- Ce rtain weather and operating conditions
such as driving through water, dr iv ing 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
pa ired by dr iv ing 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.
