the brake fluid reservoir is too low. If you believe that it is safe to do so, proceed
immediately at low speed to the nearest
authorized Audi dealer or qualified repair
facility and have the brake system in­
spected.
- Always keep in m ind that after several
brake applicat ions, you will need greater
pressure on the b rake pedal to stop your
vehicle . Do not re ly on stra ined brakes to
respond w ith maximum stopp ing power
in cri tic al situations. You must a llow for
increased bra king distances. The extra
distance used up by fad ing brakes could
lead to an accident.

When you are driving at higher speeds wit h
the windshield wipers on, the brake pads will briefly touch the brake d iscs in regular inter­
vals so as to improve reaction t ime when brak­
ing on wet surfaces. You, the driver, will not
notice anything .
The effectiveness of the brakes can be reduced
when the vehicle is driven on a salt-covered
road and the brakes are not used . Here too,
you should clean
off accumulated salt coat ing
from brake discs and pads with a few careful
applications of the brake ¢ & .
Cor ro sion
There may be a tendency for dirt to build up
on the brake pads and corrosion to form on
the discs if the car is not dr iven regularly or
only for sho rt trips with little use of the
b rakes .
If the brakes are not used frequently, or if cor­ rosion has formed on the discs, it is advisable
to clean
off the pads and discs by b rak ing
fi rm ly a few times from a mode rately h igh
speed ¢.& .
Faults in the brake system
If you should notice a sudden increase in
brake peda l travel, t hen one of the two brake
circu its may have failed¢& .
Low brake flu id le vel
Malfunct ions can occur in the brake system if
the brake fl uid level is too low . T he brake fluid
level is monitored electronically .
Brake booste r
The brake booster increases the pressure t hat
you generate w ith the bra ke pedal. It on ly op­
erates while the eng ine is running¢ &.
Brake lining wear statu s
Brake lining wea r may be c hecked by vis ual in­
spection of the condition of the brake pads
through the openings in the whee l. If neces ­
sary, the whee l may be removed for this in­
spection ¢

A WARNING
-You should perform braking maneuvers
for the purpose of cleaning the brake
system only if road conditions permit.
Othe r road use rs must not be put at risk -
you may ca use an accident!
- Before descend ing a steep grade, reduce
speed a nd s hift transmission into a lower
gea r o r l ower dr iving range. Do not ride
the br akes or ho ld t he pedal down too
long o r too often. This could cause the
brakes to get hot and diminish braking
efficiency .
- Do not " ride the brakes" by rest ing you r
foot on the pedal when you do not intend
to brake. This may ca use the brakes to
overheat, premature wear and increased
stopping distance .
- Under certain cl imatic and ope rat ing
conditions such as passing thro ugh wa­
ter , dr iv ing in heavy rain o r after washing
the vehicle , the effectiveness of the
brakes can be reduced . In winte r, ice can
accumu late on the bra ke pads, lin ings,
d iscs a nd drum s. Carefu lly app ly bra ke s
for a test. Brakes w ill dry and ice co at­
ings w ill be cleaned
off after a few care­
fu l brake applicat ions.
- Driving for an exten ded period o f time o n
salt -cove red roads without using your
brakes can a lso affect braking efficiency .
C lean
off accum ulated salt coating from
brake discs and pads with a few careful
brake applications.
- I f you damage the front spoiler, o r if you
install a different spoiler, be sure the air
f low to the front brakes is not obstruct­
ed. Otherw ise the brak e system could
overheat reducing the effectiveness of
the entire brake system.
- Failure of one b rake circuit will impai r
the braking capab ility result ing in an in­
creased s topping distance. Avoid driving
the vehicle a nd have it towed to the ne ar­
est a uthorized Audi dea le r or qu alified
wo rkshop.

228 Intellig ent technol ogy
- Never let the vehicle ro ll to a stop with
the engine shut off.
- If the brake booster is not working, the
brake pedal must be pressed considera­
bly harder to make up for the lack of
booster assistance.
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 sys­
tem senses the road speed and electronically
adjusts powe r assistance to provide comforta­
b le and safe steering response exact ly match­
ed to the vehicle speed.
Power steering w ill not work if the eng ine is
off. As a result, the steering wheel w ill be hard
to turn.
The power steering fluid level is checked dur­
ing the scheduled ma intenance serv ices .
@ Note
If the re is an electronic malfunct ion, ser­
votronic
w ill still function like a conven­
tional power steer ing system, p roviding a
constant steer ing support force that is no
longer proportionate to the vehicle speed .
This is most noticeab le when turning the
steering whee l at low speeds (for examp le
when parking), -more effort will be re­
quired than usual.
- Be aware of the different than usua l
steering response and adjust your steer­ i ng force accord ingly.
- Have the prob lem checked and set right
by an Aud i dealer as soon as possible.
- When the engine is running , never hold
the steering whee l turned all the way to
the right or to the left for longer than
15
seconds . The power steer ing pump w ill
overheat the hydraulic flu id if you keep holding the steering wheel turned all the
way . This is likely to damage the power
steering system.
- If the powe r stee ring system sho uld fail
entirely, or if the engine is not running
(for example, whi le be ing towed), you
will still be able to steer the ve hicle.
However,
considerably more effort will
be required to do so .
- If the power steering system should
have a leak, or is not functioning proper­
ly, contact your author ized Audi dealer
immediately .
- The power steering system requ ires a
specially formulated hyd ra ulic fluid . The
powe r stee ring reservoir is the one locat­
ed farthest to the rear on the left s ide of
the engine comp artment r=;,
page 259.
T he correct fluid level in the reservoir is
important for proper functioning of the
power steering .
Driving with your
quattro
With all-wheel drive , all four wheels are driv­
en .
Gen eral information
With all-wheel drive, power is distributed to
all four wheels. This happens au toma tically
depending on your driving style and the road
condit ions at the time . See also r=;,
page 224 .
Winter tire s
When driving in the winter, yo ur vehicle with
a ll-wheel drive has an advantage, even wi th
regular tires . In winter road conditions it may
be advisable to mount winter tires (or all -sea ­
son tires) for improved dr iveability and brak­
ing : these tires must be mounted o n
all four
wheels. See also r=;, page 288, Winter tires.
Tire chains
Where tire chains are mandatory on certain
roads, this normally also appl ies to veh icles
with all-wheel driver=;,
page 289, Snow
chains .

Driving off road
Driving in difficult road
conditions and offroad
General information
The operation of the E lectronic Stabilization
Control (ESC) is expanded fo r operation away
from paved roads. In situations where slip or a
differential lock ing funct ion is required, the
offroad mode can be activated
c:::> page 224.
Hill descent control is a lso ava ilable in the off ­
road mode, which automat ically brakes the
ve hicl e and thereby keeps speed consta nt
when differe nt w heel speeds a re detected
when descending a hill
c:::> page 226. Your A ud i
a lso has permanent a ll-wheel drive in addi­
tion.
H oweve r, your Aud i is not a pure off road ve hi­
cle . It was not built for d riving unde r extreme
conditions, e.g. for trips that are in the nat ure
of an expedition .
Drive only on road s and offro ad sections
which match the de sign of y our vehicl e and
you r abilitie s as a dri ver. Ne ver t ake ri sks!
Before driving offroad
- Check the eng ine oi l level, t ire pressu re ,
coolant level , and the fluid level in the w ind­
shield washe r reservo ir.
- Stow luggage items a nd other objects in the
l uggage compartment, and sec ure t hem
against s lid ing aro und .
After driving offroad
- After trips off road, remove any twigs and
othe r foreign objects from the grill , the un­
derbody and the wheels. Pay spec ia l atten­
t ion to fore ign ob jects (stones) which have
become lodged in t he tire tre ad.
- Clean t he body and the vehicle unders ide,
and inspect the veh icle for possible damage.
- Clean dirty w indows , headlamp lenses, rear
li gh ts, and license plates .
- Perfo rm a brake check (particularly after
t ravell ing throug h water) .
Driving off road 237
A WARNING
-Drive especially attentively and plan
ahead in diff icu lt road conditions and
when off road. Excessive speed o r inco r­
rect maneuve rs can cause injuries and
damage to the vehicle.
-
- Always adapt your speed and driving
style to road, offroad, t raff ic, and weath­
e r condition s. D rive e spe cially slowly off­
road when yo ur view is restricted.
- Please be aware that in offroad mode,
pa rti cularly on a smoo th and s lippery
road, the whee ls may have an increased
tendency to spin and the vehicle may
break away -danger of skidding!
- Stability is limited in the offroad mode .
