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 situat ions, for example after driving
through water, in heavy ra in, after overn ight 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 carefu l brake applications.
At higher speeds and with the w indshie ld w ipers
turned on, the brake pads press against the brake
rotors for a short amount of time. This occurs at
regular intervals without the driver noticing and
provides for better brake response time under
wet conditions.
The effectiveness of the brakes can be reduced
when the vehicle is driven on a salt-covered road
and the brakes are not used. Likewise, you clean
off accumulated salt coating from brake discs
and pads with a few cautious applications of the
brake ¢.& .
Corrosion
There 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 only for short
tr ips with little use of the brakes.
If the brakes are not used frequently, or if corro­
sion has formed on the discs, it is advisab le to
clean off the pads and discs by braking firmly a
few t imes from a moderately high speed¢.&.
Faults in the brake system
If you should notice a sudden increase in brake
pedal trave l, then one of the two brake circuits
may have failed
c:> .& .
Low brake fluid level
Malfunctions can occur in the brake system if the
brake fluid level is too low. The brake fluid leve l is
~ monitored e lectronically.

Smart Technology
Brake booster
T he brake booster increases the pressure that you
generate w ith the brake pedal.
It works on ly
when the engine is running
.c:> .&
Brake lining wear status
Brake lining wear may be checked by visual in­
spect ion of the condition of the brake pads
through the openings in the wheel. If necessary,
the wheel may be removed for this inspection
c:> page 230, Replacing wheels.
_8 WARNING "'---
-New brake pads don't have the best stop­
pin g power and must be "broken-in" during
the initial 250 miles (400 kilometers). You
can compensate for this by press ing the
brake pedal more firmly. This also applies
later when new pads are installed.
-
- You shou ld perform braking maneuvers for
the purpose of cleaning the brake system
only if road conditions permit. Other road
users must not be put at r isk -you may
cause an acciden t!
- Before descending a steep grade, reduce
speed and shift transmission into a lower
gear or lower driving range. 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 braking 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 over­
heat, premature wear and increased stop­
p in g distance.
- Under certain cl imatic and operat ing condi­
tions such as passing through water, dr iv ing
in heavy rain or after washing the vehicle,
the effectiveness of the brakes can be re­
duced. In winter, ice can accumulate on the
b rak e pads, linings, discs and drums. Care­
fully apply brakes for a test. Brakes will dry
and ice coatings will be cleaned off after a
few careful brake applications.
- Driving for an extended period of time on
salt -covered roads wi thout using your
brakes can a lso affect braking efficiency .

Trailer mode Driving with a trailer
General information
Your Audi was designed primarily for passenger
transportation.
If you plan to tow a tra iler, p lease remember that
the additiona l load will affect durability, econo­
my and performance .
T railer towing not on ly places more stress on the
vehicle, it also calls for more concentrat ion from
the driver .
F or this reason, a lways fo llow the operating and
d riving instructions provided and use common
sense.
Technical requirements
Traile r hitch
Use a weight-carrying hitch conforming to the
gross trailer weight. The hitch must be suitable
for your vehicle and trailer and must be mounted
securely on the veh icle 's chassis at a technically
sound
location . Use on ly a tra iler hitc h with a re­
movable ba ll mou nt. Always chec k w ith the t ra il­
e r hitch m anu fac tur er to make sure that you a re
using the co rrec t hitch.
Do not use a bumper hitch .
The hitch must be installed in such a way that it
does not in terfere with the impact-absorbi ng
bumper system. No mod ificat ions should b e
mad e to the vehicle exhaust and brake systems .
Fr om time to t ime, c hec k t hat a ll h itch mou nti ng
bo lts remain sec urely fastened .
When you are no t tow ing a trailer,
remove the
trai ler hitch ball mount . Th is prevents the hitc h
fr om caus ing damage should you r vehicle be
s truck from behind¢,&. .
Trailer brakes
If yo ur tra iler is equipped w it h a braking system,
check to be s ure that it conforms to all regu la­
tions.
Trailer mode
T he trailer hyd raulic brake system must not be di ­
rect ly connected to the ve hicle's hydraulic b rake
system ¢.&. .
Safety chains
Alw ays use s afety ch ains be tween your ve hicle
and t he tra ile r.
Trailer lights
Tra ile r li ghts must meet all regulations. Be sure
to check w it h your author ized Audi deal er for cor­
r e ct w iring, sw itches, and relays.
Mirrors
If you are unable to see the traffic behind you us­
i ng the regular o uts ide mirrors, then you
must in ­
sta ll extended mirrors .
It is importa nt that you
always have clea r vision to the rea r.
_&. WARNING
- I f a trai ler has elec trical brake s please note
th at these b ra kes are not acti va ted by the
