& WARNING
• USA models: If the BRAKE warning light and the I warning
light come on together, the rear wheel s could lock up first under
hard braking . Rear wheel lock-up can cause loss of vehicle control
and an accident. Have your vehicle repai red immediately by you r
authorized Audi dealer or a qualified workshop. Drive slowly and
avoid sudden, hard brake applications.
• Canada models : If the brake warning light ((j)) and the ABS
warning light
~ come on together , the rear wheels could lock up
first under hard braking . Rear wheel lock-up can cause loss of
vehicle control and an accident. Have your vehicle repaired imme­
diately by your authorized Audi dealer or a qualified workshop .
Drive slowly and avoid sudden , hard brake applications.
• If the brake warning /indicator light does not go out after a few
second s and the parking brake released , or lights up while you are
driving , the fluid level in the brake fluid reservoir i s too low. If you
believe that it is safe to do so , proceed immediately at low speed
to the neare st authorized Audi dealer or qualified repair facility
and have the brake system inspected .
• Always keep in mind that after several brake applications, you
will need greater pressure on the brake pedal to stop your vehicle.
Do not rely on strained brake s to re spond with maximum stopping
power in critical situations. You must allow fo r increased braking
di stan ce s. The extra distance used up by fading brakes could lead
to an accident. •

shield wiper performs one afterwipe operation after several seconds
while driving. You can switch this function off by moving the lever to
posit ion© within 10 seconds of the afterwipe operation. The after­
wipe function is reactivated the next time the ignition is switched on.
Cleaning the headlights*. The headlight washer system* only func­
tions when the light is switched on. The headlights are automat ically
cleaned the first time and every fifth time the lever is moved to posi­
tion ®· They are also cleaned every time you hold the lever in pos it ion
© for longer than 2 seconds.
& WARNING
• The rain sensor is only intended to assist the driver . The driver
is still responsible for manually switching the wipers on according
to the visibility conditions.
• The windshield may not be treated with water-repelling wind­
shield coating agent s. Unfavorable conditions, such as wetness,
darkness, low sun, can result in increased glare. Wiper blade
chatter is also possible.
• Properly functioning windshield wiper blades are required for
a clear view and safe driving=>
page 71, "Replacing windshield
wiper blades" .
0 Note
• In the case of frost, check whether the windshield wiper blades are
frozen to the windshie ld . Switching on the windshield wipers can
damage the wiper blades!
• Prior to using a car wash, the windshield wiper system must be
switched off (lever in position 0). This helps to prevent unintentional
switching on and damage to the windshield wiper system .
[I] Tips
• The w indshield wipe rs are switched off when the ignition is turned
off . Activate the windshield wipers after the ignition is switched back
on by mov ing the windshield w iper lever to any position.
• Worn or dirty windshield wiper blades result in streaking. This can
affect the rain sensor* function. Check your windshie ld wiper blades
regularly.
• The washer fluid nozzles of the w indshield washer system are
heated at low temperatures when the ignition is on .
• When stopping temporar ily, e.g . at a traffic light, the set speed of
the windshield w ipers is automatically reduced by one speed .•

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~

& 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.

Servotronic® - advanced power
steering system
The power steering systems uses the power of the
running engine to allow precise steering with little effort .
The advanced Servotronic® power steering system senses the road
speed and ele ct ronically adjusts power assistance to provide
comfortable and safe steering response exactly matched to the
veh icle speed.
Power steering will not work if the engine is off. As a resu lt, the
steeri ng wheel will be hard to turn.
T he power steeri ng fluid level is checked du ring the sched uled main ­
tenance services .
0 Note
If there is an electronic malfunction, servotronic will still function
like a conventional power s teer ing system, provid ing a cons tant
steering support force that is no longer proportionate to the vehicle
speed. This is most noticeable when t urning the s teer ing wheel at low
speeds (for example when park ing), -more effort will be required
than us ua l.
• Be aware of the d ifferent than usual steering response and adjust
your stee ring force accord ingly .
• Have the prob lem checked and set right by an Audi dealer as soon
as possib le.
[ i ] Tips
• When the e ngine is running, neve r hold the stee ring whee l turned
all the way to the right or to the left for longer than 15 seconds. The
powe r steering pump wi ll overheat the hydra ulic fluid if yo u keep
holding the steering wheel turned all the way . This is likely to damage
t he power s teer ing system . •
If the power steering system s hou ld fa il entirely, or if the engine
is no t ru nning (fo r examp le, while be ing towed), you will st ill be able
to steer the vehicle. However,
considerably more effort will be
req uired to do so .
• If the power steering system should have a leak, or is not func­
tioning prope rly, con tact your au thor ized A udi dealer immedia tely.
• The power steer ing system requires a specia lly formulated
hyd raulic fluid. The power steer ing rese rvoir is the one loc ated
farthest to the rear on the left s ide of the eng ine compartme nt
