Clear vision
in the interval wipe position and then come back
a while later and drive off, the rain sensor will re­
activate itself after the vehicle speed has exceed­
ed 4 mph (6 km/h).
The rain sensor* is only activated with the wiper
lever set to position(!). When it starts to rain,
the rain sensor will automatically activate the in­
termittent wiping mode.
To reduce the sensitivity of the sensor, move
switch @ down. To increase the sensitivity, move
the switch up. The higher you adjust the sensitivi­
ty, the faster the sensor will react when it senses moisture on the windshield. The pauses between
wiper turns depend not only on the sensitivity setting, but on the vehicle speed as well.
During brief stops, e.g . at a red light, wiper mo­
tion will automatically be reduced to the next
lower speed . Wipers already turning at low speed
change to intermittent wiping.
When the ignition is turned on, the washer jets
are heated.
A WARNING
- Wiper blades are crucial for safe driving! On­
ly when they are in good condition are they
able to clear the windows properly to pro­
vide uncompromising visibility. Worn or
damaged wiper blades are a safety hazard
¢ page 53, Replacing windshield wiper
blades!
- The light/rain sensor* is only designed to as­
sist and support the driver. It remains en­
tirely the driver's responsibility to monitor outside weather conditions and to manually
activate the wipers as soon as rain or drizzle
reduces visibility through the windshield .
- The windshield must not be treated with
water-repellent materials. They can increase
glare under poor visibility conditions such as
wetness, darkness, or when the sun is low
on the horizon . In addition, they can cause
the windshield wipers to chatter.
(D Note
In freezing or near freezing conditions:
52
- Always check that the wiper blades are not
frozen to the glass before you turn the wip­
ers on. Loosen a wiper blade which is frozen
in place before operating the wipers to pre­
vent damage to the wiper blade or the wiper
motor .
- Do not use the wipers to clear a frosted win­
dow. Using the wipers as a convenient ice
scraper will destroy the wiper blades .
- Before you take your vehicle to an automatic
car wash, make sure you have the wind­
shield wiper system switched off (lever in position
0), otherwise the windshield wiper
system could get damaged in the car wash if
it should suddenly come on.
(D Tips
- The windshield wipers are switched off
when the ignition is turned off. Activate the
windshield wipers after the ignition is
switched back on by moving the windshield
wiper lever to any position.
- Worn or dirty windshield wiper blades cause
smearing, which can affect the operation of
the light/rain sensor*. Check the condition
of your windshield wiper blades regularly.
- The rain sensor is part of the interval wiping
system. Turning off the ignition will also de­
activate the rain sensor . To reactivate the
sensor, switch off the interval wiping func­
tion, then switch it back on again.
- Applies to vehicles with light/rain sensor:
When the wipers are switched on manually
and in rain conditions, the automatic head­
lights* turn on <=>
page 46, Lights or off dur­
ing the day when the wipers are no longer
operating. The automatic headlights* func­
tion is available in this case only when the
light switch is in the "AUTO" position
<=>
page 46, fig. 55.
- Make sure the washer fluid reservoir in the
engine compartment is topped off before
going on a long trip. Look up<=>
page 168
for checking and filling the washer contain­
er.
- The wipers only operate with the hood com­
pletely closed.

... Move the steering wheel to the desired posi­
tion .
... Push the lever against the steering column un-
til it locks .
There must be at least 10 inches (25 cm) be­
tween your chest and the center of the steering
wheel. If you cannot sit more than 10 inches (25
cm) from the steering wheel, see if adaptive
equipment is ava ilable to help you reach the ped­
als and increase the distance from the steering
wheel.
For detailed information on how to adjust the
driver's seat, see
¢ page 57.
A WARNING
Improper use of steering wheel adjustment
and improper seating position can cause seri­
ous pe rsonal injury.
- Adjust the steering wheel column only when
the vehicle is not moving to prevent loss of
vehicle control.
- Adjust the driver's seat or stee ring wheel so
that there is a minimum of 10 inches (25
cm) between your chest and the steering
wheel¢
page 87, fig. 100. If you cannot
maintain this min imum distance, the airbag
system cannot protect you proper ly.
66
- If physical limitations prevent you from sit­
ting 10 inches (25 cm) or more from the steering wheel, check with your authorized
Audi dealer to see if adaptive equipment is
available.
- If the steering wheel is aligned with your
face, the supplemental dr iver's airbag can­
not p rov ide as much protection in an acci­
dent. Always make sure that the steering
wheel is aligned with your chest.
- Always hold the steering wheel w ith your
hands at the 9 o'clock and 3 o'clock posi­
tions to reduce the risk of persona l injury if
the dr iver's airbag dep loys.
- Never hold the steering wheel at the 12 o'clock position or with your hands inside
the steering wheel rim or on the steering
wheel h ub. Holding the steering wheel the
wrong way can cause serious injuries to the hands, arms and head if the driver's airbag
deploys.

Braking
What affects braking efficiency?
New brake pad s
During the f irst 250 miles (400 km), new brake
pads do not possess the ir full braking effect, they
have to be "broken in" first¢.&. . The break- in pe­
riod can be considerab ly longer for vehicles w ith
ceramic b rake roto rs*. You can compensate for
this s light ly reduced b ra ki ng power by push ing
ha rder on the b rake peda l. Avoid heavy braking
loads during the bre ak-in period.
136
Operating conditions and driving habits
The bra kes on today's automobiles a re s till sub­
j ect to wear, depend ing largely on operating con ­
ditions and driving habits ¢& . On vehicles that
a re either driven most ly in stop-and-go city traf­
fic or are driven hard, the brake pads should be
checked by your authorized Aud i dealer more of­
te n tha n specified in the Warranty
& Maint e­
nance bookl et. Failure to have you r brake pads
i nspected can resu lt in reduced b rake pe rform­
ance.
On steep slopes, you shou ld use the braking ef­
fect of the engine . This way, you prevent un nec­
essary wear on the brake system . If you must use
you r brakes, do not hold the bra kes down cont in­
u o usly. Pump the brakes at in tervals.
Operating noise
Noises may occur when braki ng depending on the
speed, braking force and outs ide cond it ions such
as tempera ture and hum idity.
Due to the nature of the materia ls used i n ceram­
i c brake rotors*, noises may become more appa­
r ent at low speeds.
Effect of water and road salt
In certa in situations, for examp le after driv ing
through water , in heavy rain, after overnight con­
densation or after washing your car, the braking
effect can be reduced by moisture or ice on the
brake rotors and brake pads . The brakes must be
dr ied fi rst w ith a few careful b rake app lications.
At higher speeds and with the windsh ield wipers
turned on, the brake pads press against the brake r otors for a short amount of time. This occurs at
r egular intervals without the dr iver not ic ing and
provides fo r be tter brake response time under
wet cond it ions.
The effect iveness of the brakes ca n be red uced
when the v ehicle is d riv en on a salt-cove red road
and the b rakes are no t used. Likewise, you clean
off a ccumula ted salt coating from b rake d iscs
and pads with a few ca utious app lications of the
brake ¢& .
D ue to the ir sur fa ce character istics, cerami c
brake ro tors * absorb moistu re in such co ndi tions . ..,.

..... N
r-­N "': ..... \!) 1.1'1
N 1.1'1 .....
This can cause a temporary reduction in braking
force compared to dry brakes. You can compen­
sate for this by pressing the brake pedal harder.
Cor ro sion
There may be a tendency for dirt to bui ld up on
the brake pads and corrosion to fo rm on the discs
if the car is not driven regularly or only for short
trips with little use of the brakes.
If the b rakes are not used frequently, or if corro­
sion has formed on the discs, it is advisab le to
clean off the pads and discs by braking firmly a
few times from a moderately high speed
c:> &. .
Faults in the brake sy stem
If you should notice a sudden increase in brake
pedal travel, then one of the two brake circuits
may have fai led
c:> .&, .
Low brak e flu id le vel
Malfunct ions can occur in the brake system if the
brake fluid level is too low. The brake flu id leve l is
monitored e lectronically.
Br ake power assis t un it
T he brake power assist unit increases the pres­
sure that you generate with the brake pedal.
It
works only when the eng ine is running .
Brak e lining wear sta tu s
Brake lining wear may be checked by visual in­
spection of the condition of the brake pads
through the openings in the wheel. If necessary,
the wheel may be removed for this inspection
c:> page 203 .
.8, WARNING
-New brake pads don't have the best stop­
ping power and must be "broken-in" during
the init ial 250 mi les ( 400 km) of normal city
driving. The break -in period can be consider­
ably longer for vehicles with ceramic brake
rotors *. You can compensate for this by
pressing the brake pedal more firmly. This
also applies later when new pads are instal­
led .
- You should perform brak ing maneuvers for
the purpose of clean ing the brake system
Int elli ge nt te chn olo gy
only if road conditions permit. Other road
users must not be put at r isk -you may
cause an accident!
- Before descending a steep grade, reduce
speed and sh ift transmission into a lower
gear or lower dr iving range. Do not ride the
brakes or hold the pedal down too long or
too often. This could cause the bra kes to get
hot and dimin ish braking effic iency .
- Do not "ride the brakes" by rest ing your foot
on the pedal when you do not intend to
brake. This may cause the brakes to over­
heat, premat ure wear and increased stop­
ping distance.
- Under certain cl imatic and operat ing condi ­
tions such as passing thro ugh water, dr iv ing
in heavy rain or after washing the vehicle,
the effectiveness of the brakes can be re­
duced . In winter, ice can accumulate on the
brake pads, lin ings, discs and drums. Care­
fully apply brakes for a test. Brakes will dry and ice coatings will be cleaned off after a
few careful brake applications.
- Driving for an extended period of t ime on
salt-covered roads without using your brakes can also affect braking efficiency .
Clean off accum ulated salt coating from
b rake discs and pads with a few cautious
brake applications.
- If you damage the front spoiler, or if you in­
stall a different spoiler, be su re the air flow
to the front brakes is not obstructed . O ther­
wise the brake system could overheat reduc­
ing the effectiveness of the entire brake sys­
tem .
- Fai lure of one brake circuit will impai r the
braking capability resu lting in an increased
stopping distance . Avoid driving the vehicle
and have it towed to the nearest Aud i dea ler
or qualif ied workshop.
- Never let the vehicle roll to a stop with the
engine shut off.
- If the brake booster is not working, for ex­
ample when towing your veh icle, or because
the brake booster has somehow been dam­
aged, the brake pedal must be pressed con ­
siderably harder to make up for the lack of booster assistance.

Power steering
When the engine is running, power steering
makes i t easier for the driver to steer.
Power steering helps the driver steer the vehicle
with litt le physical effort.
If the engine is not running, the power steering
system is also not working. In this case, you will
find it extremely difficult to turn the steering
wheel.
If you turn the steering fully to the left or right
when the vehicle is stationary, you place a very
heavy load on the power steering system. Turning
the steering wheel fully to the left or right wi ll
cause noise in the system . It also reduces engine
idle speed.
(D Note
Do not hold the steering turned fully to the
left or right for more than 10 seconds when
the engine is running. There is a risk of dam­
age to the power steering system.
@ Tips
- In the event of a power steering system fail­
ure, or if the engine is not running (while
being towed), you will still be able to steer
the vehicle. However, you will require more
effort to do so.
- If the power steering system has a leak or is
defective, you should immediately contact a
qualified workshop .
- The power steering system requires a spe­
cial hydraul ic fluid . The power steering fluid
reservoir is located in the engine compart­
ment. The correct hydraulic fluid level is im­
portant for proper operation of the power
steering system. The power steering fluid
l evel is checked according to the Audi main­
tenance service schedule.
Dry sump lubrication
High lateral and longitudinal forces affect the en­
gine and the vehicle during sporty driving. Dry
sump lubrication ensures that your engine is sup-
Intelligent technology
plied with oil and properly lubricated even under
these conditions.
In a "norma l" vehicle the oil pump sends the oil
from the oil pan to the lubrication points in the
engine . The oil then returns to the oil pan. In ex­
treme situations, the oil pump may draw in air,
wh ich results in insufficient oi l pressure .
With dry sump lubrica tion, the oil is not in the oil
pan (it is "dry"), but in a separate oi l tank. While
one pump supplies the engine with oil, a second
pump suct ions the oil out of the engine and re­
turns it to the o il tank. Because the oil tank is tall
and narrow, oil pressure is constant even under
extreme conditions .
In add ition, the oi l pan in vehicles with dry sump
lubrication is noticeably shallower . This allows
the engine to be installed lower in the vehicle,
bringing down the center of gravity . This im ­
proves your vehicle's handling.
Driving with your quattro
With oil-wheel drive, all four wheels are driven .
General information
With all-wheel drive, power is distributed to all
four wheels . This happens automatically depend­
ing on your driving style and the road conditions
