Deactivating
- Pre ss th e b utton again . Th e ind icator light on the button
goes o ut.
The system works at speeds faster than 19 mph (30 km/h) .
& WARNING
• Improper reliance on the side assist system can cause collisions
and seriou s per sonal injury:
- Never rely only on side assist when changing lanes.
- Alway s check rear view mirrors to make sure that it is safe to
change lanes.
• Side assist cannot detect all vehicles under all condition s­
danger of accident!
• Side a ssist cannot detect vehicle s
in time to alert you when
they approach from behind at very high speed , or fall drop bac;k
very quickly .
• The radar sensor's
vision can be reduced o r entirely blocked by
rain, snow, and heavy spray . Thi s can result in side a ssist not
adequately detecting vehicles o r, in some cases , not detecting
them at all. Always keep an eye on the direction you are traveling
and the relevant area around the vehicle.
• Plea se note that side assi st indi cates there are approaching
veh icles, or vehicles in your blind spot, only after your vehicle has
reached a driving speed of at lea st 19 mph (30 km/h).
• Side assist signal does not work around tight corners (turning
radius le ss than 328 feet or 100 m).
• Side assist is no replacement for the driver's full attention. The
driver alone is respon sible for lane changes and similar driving
maneuvers. Always keep an eye on the direction you are traveling
and the relevant area around the vehicle .

ment Safety first
0 Note
• T
o ens ure t hat you do not adve rsely affec t side assist, do not blo ck
the area on the rear bumper where the radar sensors are located with
foreign obje cts (s uch as stickers or bicy cle ra cks).
• Make s ure that the s ignal light on the outside mirror is not
blo cked by st ickers or o ther ite ms.

Corrosion
T he re may be a te ndency fo r d irt to build u p on the bra ke pads and
co rrosion to form on the d iscs if the car is not dr iven reg ularly o r only
for short trips with litt le use of the bra kes .
If the brakes a re not used freq uen tly, or if co rrosion has formed o n
the discs, it is advisable to clean off the pads and discs by braking
fir mly a few times from a mode rat ely h igh spee d~ & .
Faults in the brake system
If yo u sh ou ld noti ce a sudden increase in b rake peda l trave l, then one
of the two brake circu its may have failed~& .
Low brake fluid level
Ma lfunctions can occ ur in t he brake system if the brake fluid level is
t oo low. The bra ke f lu id level is moni tore d elec tron ically.
Brake lin ing wear status
Brake lin ing wear may be checked by v isua l inspect ion of the condi­
tion of the brake pads throu gh the open ings in the whee l.
If neces­
sary, the whe el may be removed fo r thi s insp ection~
page 320,
"Changing a w hee l".
& WARNING
• You should perform braking maneuvers for the purpose of
cleaning the brake system only if road conditions permit. Other
road users must not be put at risk - you may cau se an accident!
• Before descending a steep grade, reduce speed and shift trans­
mission 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 overheat ,
premature wear and increased stopping distance.
• Under certain climatic and operating condition s such as
passing through water , driving in heavy rain or after washing the
& WARNING (co ntinued )
vehicle, the effectiveness of the brakes can be reduced . In winter,
ice can ac cumulate on the brake pads, linings, dis cs and drums.
Carefully apply brakes for a test. Brakes will dry and ice coatings
will be cleaned off after a few careful brake appli cations.
• Driving for an extended period of time on salt-covered roads
without u sing your brakes can also affect braking efficiency . Clean
off accumulated salt coating from b rake discs and pads with a few
careful brake applic ations.
• If you damage the front spoiler, or if you install a different
spoiler, be sure the air flow to the front brakes i s not obstructed .
Otherwise the brake system could overheat reducing the effective­
ness of the entire brake system.
• Failure of one brake circuit will impair the braking capability
resulting in an increased stopping di stance. Avoid driving the
vehicle and have it towed to the nearest authorized Audi dealer or
qualified workshop.

& WARNING
• Never let the vehicle roll to a stop with the engine shut off.
• If the brake booster is not working, for example when towing
your vehicle , or because the brake booster has somehow been
damaged, the brake pedal mu st be pressed considerably harder to
make up for the lack of booster assistance. •

New brake pads
- -
Remem ber th at new brake pads do not have a full braking
e ffe ct du ring the first 250 mi les (400 ki lo mete rs) afte r they
are in sta lle d .
N ew br ake pads have to be " burnishe d in" before they have op tim al
grab~ &-
Dur ing the break-in period, you sho uld avoid putting severe loads on
the brakes . Severe loads include, for example, sudden ha rd bra king,
in part icu lar at very high s peeds o r, for example, on mountain passes .
& WARNING
New brake pads don't have the best stopping power and must be
" broken-in " during the in itial 100 to 150 miles (150 to 200 kilo ­
meters) of normal city driving. You can compensate for this by
pressing the brake pedal mor e firmly . This also applies later when
new pads are installed. n
Avoid damaging the vehicle
When yo u are driving on poor roads, or over c urbs, steep ramps, etc.,
ma ke ce rtain that low-lying pa rts su ch as spoilers and exhaust system
parts do not bottom out and get damaged .
This is es peciall y tr ue for veh icle s wi th low-slung chass is (sports
chassis)" and fully loaded vehicles. •
Driving through water on roads
Note the following to avoid vehicle damage w hen drivi ng through
water, fo r examp le on floode d roa ds:

The wate r must not be any higher than the bottom of the vehicle
body .
• Do not drive faster than wa lking speed.
& WARNING
After driving through water , mud , slush , etc ., the brakes may be
slow to take effect because of wet brake rotors and pads . Dry the
brakes first by braking carefully to resto re the full braking effect.

Vehicle care Do-it-yourself service Technical data

Driving and environment
- Never put too much motor oil in your engine=> page 284,
"Adding engine oil~".
- Never try to pus h- or tow-sta rt your vehicle.
The catalytic converter is an efficient "clean-up" dev ice built into the
exhaust system of the vehicle. The catalytic converter burns many of
the pollutants in the exhaust gas before they are released into the
atmosphere.
T he exclusive use of unleaded fuel is c riti cal ly import ant for the life of
the catalytic converter and proper funct io ni ng of the eng ine.
& WARNING
• Do not park or operate the vehicle in areas where the hot
exhaust sy stem may come in conta ct with dry gras s, brush, fuel
spill or other material which can cause a fire.
• Do not apply addit ional undercoat ing or rustproofing on or
near the exhaust manifold , exhau st pipes , catalytic converte r or
heat shield s. During driving, the sub stan ce u sed f or under coating
c ould o ve rheat and cause a fire.
0 Note
• Be aware that just one tank filling with leaded fuel w ill already
ser iously degr ade the performance of the ca talytic co nve rter.
• Do not exceed the correct engine oil level =>
page 284.
• Do not dr ive until the f uel tank becomes com plete ly empty . T he
engine could misfire . Unburned fuel cou ld also get into the ex ha ust
system and t his co ul d cause t he ca talyt ic converter to ove rheat .
• Do not turn off the ignition while the vehicle is moving.
• Do not continue to operate your vehicle u nder these conditions, as
otherwise f uel can reac h the c ata ly tic conve rter. This co uld res ult in
over heat ing of the converter, requir ing its replacement.
• T o ass ure eff icien t operat ion of the Emission Cont rol System: -
Have your vehicle maintained properly and in accordance with
th e se rvice reco mmend ations in your W arran ty
& M ain ten ance
booklet.
- Lack of prope r main ten anc e as well as imp roper use of the
veh icle w ill impair the fu nction of the emission control system and
c o uld l ead to d amage.
~ For the sake of the environment
Even when the Emission Contro l System is operat ing proper ly, the
exhaust gas can have a sulfur-like exhaust gas smell u nder some
operating states. This depends on t he sulfur content of the fue l being
used . Using a different brand of fuel may help , o r fil lin g the tank with
