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: Sand RS 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 fu ll
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 whe n driving through
water.

A WARNING
-You should only switch sport mode on or
switch ESC/ ASR off if your driving abilities
and road conditions permit.
- The stabilization function is limited when
sport mode is switched on. The driving
wheels could spin and the vehicle could swerve, especially on slick or slippery road
surfaces.
- There is no vehicle stabilization when ESC/
ASR are switched off.
(D Tips
- ESC/ASR cannot be switched off or sport
mode cannot be switched on if the cruise
control system* or the adaptive cruise con­
trol* is switched on.
- If the rear spoiler system malfunctions,
sport mode may not switch on or it may
switch off again automatically.
Brakes
New brake pads
-
New brake pads do not achieve their full braking
effe ct during the first 2S0 mi (400 km). They
must be "broken in" first.
The break-in period can be considerably longer
for vehicles with ceramic brake rotors*. However,
you can compensate for the slightly reduced
122
braking force by pressing firmly on the brake
pedal. Avoid heavy braking during the break-in
period.
Wear
Brake pad
wear depends large ly on the way the
vehicle is driven and on operating conditions .
This is espec ia lly true if you are driv ing frequently
i n 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.
Noises may become more apparent at lower
speeds due to the nature of the materials in the
ceramic brake rotors*.
Effect of water and road salt
In certain situations, for example after driving
through water, in heavy rain, after overnight con­
densation 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 carefu l brake applica­
tions.
At higher speeds and with the windshield 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 dr iver, happens at regular
IJIJ,

a co .... N
" N .... 0 00 \.J ' 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
first when the brakes are applied.
Due to its surface, the ceramic brake rotor* ab­
sorbs moisture in certain situations. Therefore,
there will temporarily be less braking force than
when the brakes are dry. You can compensate for
this by pressing the brake pedal harder.
Corrosion
Leaving the vehicle parked for long periods of
time, low mileage and avoiding heavy braking
can contribute to corrosion on the brake rotors
and to dirty brake pads.
If you usually avoid heavy braking or if there is
corrosion 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
circuit brake system may have malfunctioned. Drive to an authorized Audi dealer or authorized
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 pedal harder .
Low brake fluid level
When the brake fluid level is low, malfunctions in
the brake system may occur . The brake fluid level
is electronically monitored .
Brake booster
The brake booster amplifies the pressure you ap­
ply to the brake pedal. It only works when the en­
gine is running.
A WARNING
-Only apply the brakes for the purpose of
cleaning the brake system when road and
-
Intelligent Technology
traffic conditions 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 achieve their full
braking effect during the first 250 mi
(400 km) . They must be "broken in" first.
The break-in period can be considerably lon­
ger for vehicles with ceramic brake rotors*.
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.
- 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
tance. Avoid driving the vehicle and have it
towed it to the nearest authorized Audi
dealer or authorized Audi Service Facility.
- 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 .
@ Note
-Never let the brakes "rub" by pressing the
pedal lightly when braking is not actually

" N .... 0 00 \.J ' & WARNING
-Only wash the vehicle when the ignition is
off and follow the instructions from the ca r
was h operator to reduce the risk of acci­
dents.
-T o red uce the risk of cuts, protect yourself
from sha rp metal components when wash­
ing the underbody or the inside of t he wheel
hous ings .
-After wash ing the vehicle, the brak ing effect
may be delayed due to mo isture on the
brake rotors or ice in the w inter . This in­
c reases the risk of an acc ide nt. The bra kes
