Brakes
New brake pads
New b ra ke pads do not achieve their full brak­
i n g effect d uring the first
4 00 km. They must
be "broken in" first. However, yo u can com ­
pensate for the slightly reduced braking force
by pressing firmly on the brake pedal. Avoid
heavy brak ing duri ng the break- in period.
Wear
Brake pad
wear is largely dependent on the
way the vehicle is driven and on operating
cond it ions . This is especially true if you are
driv ing frequently in the city and on curves or
with a sporty d riving style .
Operating noise
Noises may occur when bra king depending on
the speed, brak ing force and outs ide condi­
tions such as temperature and humid ity.
Effect of water and road salt
In certa in situations, for examp le after driv ing
th ro ugh water, in heavy rain, after overnight
condensation or after was hing your car, the
braking effect can be reduced by mois ture or
ice on the brake rotors and brake pads . The
brakes must be "d ried" first with
a few car eful
brake applications .
At higher speeds and with the windsh ield wip­
ers turned on, the brake pads press against
the b rake ro to rs fo r a shor t amo unt of t ime .
T h is act ion whi ch is not felt by the driver hap­
pens at reg ular intervals and facilita tes a bet­
t e r r ea ct ion time for the br ake s in we t wea th­
er.
T he bra king effect can a lso be reduced if you
are driv ing o n salted roa ds an d you do not ap­
ply the br akes fo r long peri ods of time. The
l aye r of sa lt on the brake rotors and pads
must be wo rn off first when the b rakes are ap -
plied. .,.

192 Smart T echnol ogy
Corro sion
Leaving the vehicle parked for long periods o f
time, low mi leage and avoiding heavy braking
can contribute to corrosion on the brake ro­
tors and di rty brake pads.
I f you usually avoid heavy brak ing 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 your authorized Audi
dealer or qualified repair facility immediately
to hav e 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 .
Lo w 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 mon itored.
B rake bo ost er
The brake booster amplifies the pressure you
apply to the brake pedal. It only works when
the engine is running.
A WARNING ,~ ·
- You should only 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 gea r or lowe r selector lev­
er position. Drive as litt le as poss ible
w hil e pressing the bra ke peda l and avoid
putt ing you r left foot on the brake pedal
whi le driving . This could cause 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. This can cause the brakes to overheat
in-
,
crease wear and increase braking dis­
tance unnecessarily.
- 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
bu ild up on the bra ke pads, rotors and
d rums. Che ck these components by b rak­
ing caref ully. App lyi ng the br akes care­
fu lly several times dries the brakes and
removes ice bui ld-up .
- The eff ic iency of the brakes can also be
impaired by driving for long stretches on roads covered with salt without using the
brakes. Yo u 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 ic h red uces their effectiveness .
- Failure of a brake circuit impa irs braking
performance, wh ic h increases bra king
d istance . Avoid driving the vehicle and
have it towed it to the nearest author­
i z ed A udi dealer or au thorized Aud i Serv­
ice Facility .
- Do not let your ve hicle roll w it h the en­
g ine switched off unde r any circumstan­
ces .
- If the b rake booste r is no t working, you
will have to press much harder on the b rake peda l to compensate for the lack
of the booster.
(D Note
- N ever le t the bra kes "rub" by pressing
t he pedal ligh tly when braking is not
really necessary . This causes the brakes
to overheat and increases braking dis ­
tance and causes wear .
- Before dr iv ing 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 .,.

206 Care and cleaning
_& WARNING
- Only wash the vehicle when the ignition
is off and follow the instructions from
the car wash operator to reduce the risk
of accidents.
- To reduce the risk of cuts, protect your­
self from sharp meta l components when
wash ing the underbody or the inside of
the wheel housings.
- After washing the vehicle, the braking ef­
fect may be de layed 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 ions .
@ Note
- If you wash t he vehicle in an automatic
ca r wash, you must fold the exterior m ir­
r o rs in to reduce the r isk of damage to
t h e m irrors. Power foldi ng exterior m ir­
r o rs* must on ly be folded in and o ut us­
i ng the p ower folding function.
- To prevent pa int damage, do not wash
t h e ve hicle in direc t sunli ght. -
To reduce the ris k of damage to the sur ­
face, do not use insect removing spong­
es, kitchen sponges or similar items.
- Matte finish painted veh icle compo­
nents:
- To reduce the risk of damage to the
surface, do not use polishi ng agen ts or
h a rd wax.
- Never use protect ive wax. It can de­
stroy the matte fi nish effec t.
- Do not place any stickers o r mag net ic
s igns on vehicle parts painted w ith
matte fi nish pa int. The paint cou ld be
d amaged when the sticke rs o r mag nets
ar e removed. @ For the sake of the environment
Only wash the ve hicl e in facilities spec ia lly
de signed for that purpose. This will red uce
the r is k of dirty w ater contam ina ted with
oi l from entering the sewer sys tem.

274 What do I do no w?
When removing or installing the wheel,
the rim could hit the brake rotor and dam­
age the rotor. Work carefully and have a
second person help you.
Never use the hexagonal socket in the han ­
dle of the screwdriver to loosen or t ighten
the wheel bolts.
- Pull the reversible b lade from the screw­
driver before yo u use the hexagonal
socket in the handle to turn the whee l
bo lts.
- When mounting tires with
unid irectional
tread design
make sure the tread pat­
tern is pointed the r ight way
¢page 274.
- The wheel bolts should be clea n and easy
to tu rn . Check for d irt and corrosion on
the mat ing su rfaces of both the whee l
and the h ub. Remove a ll dirt from these
su rfaces before remo unti ng the wheel.
Tires with unidirectional tread design
Tires with unidirectional tread design must be
mounted with their tread pattern p ointed in
the right direction.
Using a spare tire with a tread pattern
intended for use in a specific direction
When using a sp are tire w ith a tread pa tte rn
i nten ded for use in a specific direc tion, p lease
note t he following:
- T he direction of rotation is marked by an a r­
row on the side of the tire.
- If the spare t ire has to be installed in the in­
c orrec t direction, use the spa re tire only
tempor arily si nce the t ire will no t be able to
achieve its op timum performance character­
istics with regard to aquaplaning, noise and
wear .
- We recommend tha t you pay particular a t­
tention to this fact during wet weather and
that you adjust your speed to matc h road
condit ions. -
Replace the flat ti re with a new one and
have it insta lled on your vehicle as soo n as
possible to resto re the hand ling advantages
of a unidirectional tire.
Notes on wheel changing
Please read t he information ¢ page 254, New
tires and replacing tires and wheels
if you a re
going to use a spa re tire which is different
from the t ires on you r vehicle.
After you change a tire:
- Check the tire pre ssure on the spare imme­
diately after installation .
- Have the wheel bolt tightening torque
c hecked with a torque wrench as soon as
possible by your author ized Audi dealer or
a qualified service stat ion.
- With steel and alloy wheel r ims, the wheel
bolts a re co rrectly tightened at a torque of
90 ft lb (120 Nm ).
- If you notice that the wheel bolts are cor ­
roded and difficult to turn while changing
a tire , they should be replaced before you
check the t ightening torque .
- Replace the flat tire w ith a new one and
have it installed on your vehicle as soon as
po ssible . Remount the wh eel cover.
Until then , dr ive with e xtra care and at re­
duced speeds.
A WARNING
= -
- If you are going to equ ip your vehicle
with tires o r rims which differ from those
which were facto ry installed, then be
s ure to read the information¢
page 25 4,
New tires and repla cing tires and
wheels.
- Always m ake s ure the dam age d wheel o r
even a flat tire a nd the jack and tool ki t
are properly secu red in the luggage com­
pa rtment and are not loose in the pas ­
senger compartment.
- In an accident or sudden maneuver they
could fly forwa rd, injuring anyone in the
veh icle.
