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: RS models
By warming up/cooling down the engine carefu l­
ly, you can help reduce unnecessary stra in o n
your veh icle when driving in a sporty sty le .
72
The tires only reach t heir full road ho ld ing capa ­
bility once they have warmed up under load.
Yo ur vehicle also has an afte r-run cooli ng fea ­
tu re . Howeve r, cooling down is st ill import ant.
The eng ine and t he brakes as we ll as the exhaust
system and the transmission become very hot
when driving in a sporty style. Before you shut
the veh icle off, you should cool down the vehicle
by driving a few miles at low speeds with light ac­
ce leration .
Driving through water on roads
Note the following to reduce the risk of veh icle
damage when dr iving throug h wate r, fo r example
o n flooded roads:
-The water must not be any higher than the bot ­
tom of the vehicle body .
-Do not drive faster than walk ing speed .
A WARNING
After driving thro ugh water or m ud, the effec­
tiveness of t he b rakes may be reduced due to
mo istu re o n the bra ke rotors and brake pads.
A few ca reful br ake app lica tions sho uld d ry
off the bra kes and restore the fu ll b raking ef ­
fect.
@ Note
-Vehicle components such as the e ng ine,
t ra nsmiss ion, sus pens io n or elect rical sys ­
tem can be severely damaged by d riving
throug h water.

(j) Tips
-De ter mine the dep th before dr iving throug h
w ate r.
-Do not stop the vehi cle, d rive in reverse or
switch t he e ngine off whe n driving through
water .
-Keep in mind that o ncom ing vehicles may
c re ate w aves th at r aise the wa ter level and
make i t too deep for yo ur vehicle to drive
throug h safe ly.

Intelligent Technology
-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
tro l* is switched on.
- Malfunctions in the Audi magnetic ride*
may make it impossible to switch the ESC/
ASR off or to switch sport mode on.
Brakes
New brake pads
New brake pads do not achieve their full braking
effect during the first 250 mi (400 km). They
must be "broken in" first. However, you can com­
pensate for the slightly reduced braking force by
pressing firmly on the brake pedal. Avoid heavy
braking dur ing the break-in per iod .
The break-in period can be considerably longer
for vehicles with ceramic brake rotors*. However,
you can compensate for the slightly reduced
braking force by pressing f irmly on the brake
pedal. Avoid heavy brak ing dur ing the break- in
pe riod .
Wear
Brake pad
wear depends largely on the way the
veh icle is driven and on operat ing cond itions .
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 depend ing on the
speed, braking force and outs ide cond itions 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
densat ion or after washing your car, the braking
150
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 wipe rs
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
i ntervals and ensures a better reaction t ime for
the brakes in wet weather .
The brak ing effect can also be reduced if you are
driv ing on salted roads and you do not app ly the
brakes for long periods of time. The layer of salt
on the brake rotors and pads must be worn off
first whe n the brakes are applied .
Due to its surface, the ceram ic brake rotor* ab­
sorbs moisture in certain s ituations . Therefore,
there will temporarily be less braking force than
when the brakes are dry . You can compensate for
th is by press ing the brake pedal harder.
Corrosion
Leaving the vehicle parked for long periods of
time, low mileage and avoiding heavy braking
can contribute to corros ion on the brake rotors
and to dirty brake pads.
If you usually avoid heavy braking or if there is
corrosion present, occasional heavy brak ing 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
i ncreased, then a brake circuit in the dua l­
c ir cuit brake system may have malfunctioned.
Drive to an authorized Audi dealer or authorized
Audi Service Fac il ity immed iately to have the
problem corrected. On the way there, drive with
r educed 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
t h e b rake system may occur. The b rake flu id level
is electronically monitored.

A WARNING
-Only wash the vehicle when the ignition is
off and follow the instructions from the car
wash operator to reduce the risk of acci­ dents.
-T o reduce the risk of cuts, protect yourself
from sharp metal components when wash­ ing the underbody or the inside of the wheel
hous ings .
-After wash ing the vehicle, the brak ing effect
may be de layed due to mo isture on the
brake rotors or ice in the w inter . This in­
c reases the risk of an acc ident. The brakes
must be d ried fi rst w it h a few careful b rake
app lications.
