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 .,.
