Brakes
New brake pads
-
N ew brake pads do not achieve their fu ll brak­
ing effect d urin g the first
400 km. They must
be "broken i n" first. However, yo u can com­
pensate for the slightly reduced braking force
by pressing fi rmly on t he brake pedal. Avo id
heavy brak ing dur ing the break- in period.
Wear
Brake pad
wear is largely dependent on the
way the vehicle is dr iven and on operati ng
condit io ns. This is especially true if you are
driv ing frequent ly in t he ci ty and o n curves or
with a spor ty d rivi ng s tyle.
Operating noise
Noises may occur when bra king depending on
the speed , braking force and outside condi­
t ions such as tempe rature and hum id ity.
Effect of water and road salt
In certa in situations, for examp le after dr iv ing
t hr ough water, in heavy rain, after overnight
condensation or after was hing your car, the
braking effect can be reduced by moisture or
ice on the brake rotors and brake pads. The
brakes must be "d rie d" first with a few carefu l
brake applicat ions .
At highe r speeds and with the winds hield wip­
ers tu rned on, the brake pads press against
the b rake ro to rs fo r a short a mount of t ime .
T h is act ion which is not felt by the d river hap­
pen s at reg ular i nte rvals an d facilit ates a bet­
te r rea ction t ime for the br akes in we t we ath­
er.
T he bra king effect can a lso be redu ced if you
are dr iv ing o n sal ted roads a nd you do not a p­
ply the br akes fo r long periods of time. The
l aye r of sa lt on the b rake roto rs and pads
must be wo rn off first when t he b rakes are ap -
plied. ..,..

Corrosion
Leaving the vehicle parked for long periods of
time, low mi leage and avoiding heavy braking
can contribute to corrosion on the brake ro­
tors and dirty brake pads.
If you usually avoid heavy braking or if there is
corrosion present, occasiona l heavy braking at
high speeds is recommended to clean the
brake rotors and pads~,& .
Brake system malfunction
if you notice that the brake pedal t ravel has
suddenly gotten larger, then a brake circuit
may have failed . Drive to you r authorized Audi
dealer or qualified repair facility immediately
to have the problem corrected. On the way
there, drive with reduced speed and keep in
mind that a long braking distance and in­
creased pressure on the brake pedal will be
necessary .
Low brake fluid level
When the brake fluid level is low, ma lfunc­
tions in the brake system may occur . The
brake fluid level is electronically monitored.
Brake booster
The brake booster amplifies the pressure you
apply to the brake pedal. It only works when
the eng ine is running.
A WARNING
-You should on ly perform braking maneu­
vers to clean the brakes when the road condit ions perm it . Never put others on
the road at risk -never forget the risk of
acc idents!
- On steep slopes, reduce the speed and
select a lower gear or lower selector lev­
er posi tion. Drive as little as possible
wh ile pressing the bra ke peda l and avoid
putt ing your left foot on the brake pedal
whi le driving. This could ca use the brakes
to overheat and impair the efficiency of
the brakes.
- Do not let the brakes "grind" by always
keeping yo ur foot on the brake peda l.
Smart Technolog y 191
This can cause the brakes to overheat in-,
crease wear and increase braking dis­
tance unnecessar ily.
- Certain weather and operating condi­
tions such as driving through water, driv­
ing in heavy rain or driving after washing
your veh icle can impa ir the effectiveness
of the brakes. In the winter, ice may
bui ld up on the brake pads, rotors and
drums . Check these components by brak­
ing caref ully. App lying the brakes care­
fu lly several times dries the brakes and
removes ice build-up .
- The effic iency of the brakes can also be
impaired 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 care­
fully applying the brakes several times.
- If the front spoiler is damaged or you in­
stall another spoiler, make sure the front
wheel brakes are ventilated properly.
Otherwise, the brake system could over­ heat, wh ich reduces their effectiveness .
- Failure of a brake circuit impa irs braking
performance, wh ich increases braking
d istance . Avoid driving the vehicle and
have it towed it to the nearest author­
i z ed Audi dealer or authorized Audi Serv­
ice Facility.
- Do not let your veh icle roll w ith the en­
gine switched off under any circumstan­
ces .
- If the brak e booster is not working, you
wi ll have to press much harder on the
brake peda l to compensate for the lack
of the booster.
(D Note
-Never let the brakes "rub" by pressing
the pedal lightly when braking is not
really necessary. This causes the brakes
to overheat and increases braking dis­
tance and causes wear.
- Before driving on a long stretch with
steep s lopes, reduce your speed and shift
to the next lower gear This makes use of
the engine brak ing effect and relieves ..,.

Care and cleanin g 205
& WARNING
- Only wash the vehicle when the ignition
is off and follow the instructions from
the car wash operato r to reduce the risk
of accidents.
- To reduce the risk of cuts, protect your­
self from sharp metal components when
wash ing the underbody or the inside of
the whee l housings.
- After washing the vehicle, the braking ef­
fect may be delayed due to mo isture on
the brake rotors or ice in the winter . The
brakes must be dried first with a few
careful brake applicat io ns.
{[) Note
- If you wash th e vehicle in an automatic
ca r wash, yo u m ust fold the exterior m ir­
ro rs in to reduce the r isk of damage to
the mirrors . Power foldi ng exterior m ir­
r o rs* must o nly be folded in and out us­
i ng the power folding function.
- To prevent pa int damage, do not wash
th e veh icle in direc t sun ligh t. -
To reduce the r is k of damage, do no t
wash the powe r top with a pressure
washer.
- To reduce the r is k of damage to the sur­
face, do not use i nsect removing spong­
es, kitchen sponges or similar items.
- Matte finish painted vehicle compo­
nents:
- To reduce the risk of damage to the
surfac e, do not use polishi ng agents or
ha rd wax.
- Neve r use prot ective wax. It can de­
stroy the matte fin is h effect.
- Do not place any stickers o r magnet ic
signs on vehicle parts painted w it h
