lane that is not adjacent to your current lane.
- If you are driving through a curve. Side assist may react to a vehicle that is one lane over
from th e adjacent lane .
- If s ide assist reacts to other objects (such as
high or d isplaced guard ra ils).
- In poor weather condit ions. The side assist
functions are limited.
Do not cover the radar sensors <=>
fig. 121 with
stickers, deposits, bicycle wheels o r othe r ob ­

not use side ass ist when towing a trailer. For in­
formation on cleaning, see <=>
page 306.
A WARNING
-Always pay attention to traffic and to the
area around your vehicle. Side assist cannot
rep lace a driver's attention. The driver alone
is a lways responsible for lane changes and
similar d riving maneuvers .
- In some situat ions, the system may not
func tion or its funct ion may be limited . For
example :
- if vehicles are approaching or being left
behind very quickly. The display may not
turn on in t ime .
- In poor weather conditions such as heavy
rain, snow or heavy mist .
- On very wide lanes, in tight curves, or i f
there is a rise in the road surface. Vehicles
in the adjacent lane may not be detected
because they are outs ide of the sensor
range.
- Audi side ass ist cannot detect a ll vehicles
under a ll condit ions, which can increase the
risk of accidents.
- Please note that side assist only displays ap­ proaching vehicles or vehicles in your blind
spot if your vehicle is traveling at least
19 mph (30 km/h) .
- In certain situations, the system may not
work or its function may be limited. For ex ­
amp le:
- The display may not turn on at the rig ht
time if veh ides are approaching or passing
very q uick ly .

-
- In poor weather conditions, such as heavy
rain, snow or fog .
- In very wide lanes , in tight c urves or when
there are slopes in the roadway, vehicles
i n the ne ighboring lanes may not be de­
tected because they a re outside of the
sensor range .

Brakes
New brake p ads
New b rake pads do no t achieve the ir full b raking
effect during the firs t 250 mi (400 km) . They
m ust be "broken in" first . The b reak -in period can
be considerably longe r for vehicles with ceram ic
brake rotors* . However, you can compensate for
the slightly reduced braking force by pressing
firm ly on the brake pedal. Avo id heavy braking
during the break-in period .
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 c ity 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 appare nt at lowe r
speeds due to the nature of the materia ls in the
ceramic brake rotors*.
Effect of water and road salt
I n cer tain s ituations, for example a fter driving
through water, in heavy rain, afte r ove rnig ht con ­
densation or after washing your car, the braking
effect can be red uced by moisture or ice on the
brake rotors and b rake pads . The brakes must be
"dr ied" first w ith a few care ful b rake applica­
tions .
At higher speeds and with the windshie ld wipers
turned on, the brake pads press aga inst the brake
rotors for a short amount of time. T his action,
which is no t felt by the driver, happens at regular
i n tervals a nd ensu res a better react ion time for
the bra kes in wet weather.
The braking effect can also be reduced if you are
driving on salted roads a nd you do not apply the
brakes fo r long pe riods of time. The laye r of salt
o n th e brake roto rs and pads mus t be wo rn off
fi rs t when the brakes are app lied.
128
D ue to its s urface, the ce ram ic brake rotor * ab ­
sorbs moisture in ce rtain situations. The refore,
there will tempora rily be less brak ing fo rce than
whe n the brakes are d ry . You can compensate for
th is by press ing the brake pedal harder.
Corrosion
Leav ing the ve hicl e pa rked for long periods of
time , low mileage and avoiding heavy b raking
can contrib ute to corros ion on the b rake roto rs
and to dirty brake pads.
If you usua lly avoid heavy bra king or if there is
cor rosion p resent, occasiona l heavy brak ing at
high speeds is recommended to clean the brake
rotors and pads
c> ,& .
Brake system malfunction
if you no tic e th at the b rake peda l t ravel has sud­
denly
increase d, then a bra ke circuit in the dua l­
c ir cuit b rake system may have malfunctioned.
D rive to an authorized A udi dealer or authorized
Audi Service Facility immed iate ly to have the
problem corrected . On the way there, drive w ith
reduced sp eed and keep in m ind that you wilt
need a longe r distance to stop and you will need
to press the b rake peda l ha rder.
Low b rake fluid level
When the brake fluid level is low, malfunctions in
the b rake system may occur . The brake fl uid level
i s e lec tronically moni to red.
Brake booster
The brake booster amp lifies the pressure you ap­
ply to the brake pedal. It only wor ks when the en­
gine is running.
A WARNING

N .... 0 0 :c ' -New brake pads do not achieve their fu ll
brak ing effect during the first 250 mi
(400 km). They must be "broken in" first.
However, you can compensate for the
sl ightly reduced braking force by pressing
firmly on the brake pedal. Avoid heavy brak­
ing dur ing the b reak-in per iod.
- Certa in weather and operat ing cond it ions
such as dr iving t hrough water, d riving in
heavy ra in or d riving after washing your ve­
hicle ca n impair the effectiveness of the
bra kes . In the w inter, ice may b uild up on
the brake pads, rotors and drums . Check
these components by braking carefu lly. Ap­
plying the brakes carefu lly several times
dr ies the brakes and removes ice bu ild-up.
- The effic iency of the brakes can also be im­
paired by driving for long st retches on roads
cove red w ith salt without using the b rakes.
Yo u can remove sa lt deposits from the
bra ke rotors and pads by caref ully applyi ng
the brakes severa l t imes .
- If the front spoiler is damaged or you install
another spoiler, ma ke sure the front wheel
bra kes are vent ilated prope rly. O therwise,
the br ake system could overheat, wh ic h re­
duces the ir effectiveness.
- Failure of a brake circui t impai rs b raking
perfo rmance, whi ch incre ases bra king dis­
tance . Avoi d driving the vehicle and have it
towed it to the nearest author ized Audi
dealer or authorized A udi Se rvice Facility .
- If the bra ke booster is not wor king, you will
have to press m uch ha rder on the bra ke
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 actually
necessary. This causes the brakes to over­
heat and inc reases braking d istance and
causes wear.
- Before driving downh ill a long distance on a
steep h ill, decrease your speed and select a
l ower gear. This makes use of the engine
braking effect and relieves the brakes . If Intellig
ent Technology
you need to bra ke ad ditiona lly, bra ke in in­
terva ls and not continuous ly .
(D Tips
- If the brake boos ter is not wor king, you
must press the brake peda l with much more
force than normal.
- If you retrof it your vehicle with a front spo il­
er, wheel covers or simi lar items, make su re
that the air f low to the front wheels is not
inter rupted. Otherwise the b rake system
can become too hot.
