- Never let the vehicle roll 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 power assistance to provide comforta-
ble and safe steering response exact ly match-
ed to the vehicle speed.
Power steering will not work if the eng ine is
off. As a result, the steering wheel will be hard
to turn.
The power steering fluid level is checked dur-
ing the scheduled ma intenance services.
@
Note
If the re is an electronic malfunct ion, ser-
votronic will st ill function like a conven-
tional power steer ing system, providing 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-
ing force accord ingly.
- Have the problem checked and set right
by an Audi 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 will
overheat the hydraulic fluid if you keep
holding the steering wheel turned all the
way. This is likely to damage the power
steering system.
- If the power stee ring system should fail
entirely, or if the engine is not running
(for example, while be ing towed), you
will still be able to steer the vehicle.
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 hydraulic fluid . The
power stee ring reservoir is the one locat-
ed farthest to the rear on t he left side of
the engine compartment r=;, page 259 .
The correct fluid level in t he reservoir is
important for proper functioning of the
power steering .
Driving
with
your
quattro
With all-wheel drive, all four wheels are driv-
en .
General information
With all-wheel drive, power is distributed to
all four wheels. This happens aut omat ically
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, your vehicle with
all-wheel drive has an advantage, even wit h
regular tires . In winter road conditions it may
be advisable to mount winter tires (or all-sea -
son tires) for improved driveability and brak-
ing: these tires must be mounted on
all four
wh eels.
See also r=;, page 288, Winter tires.
Tire chains
Where tire chains are mandatory on certain
roads, this normally also appl ies to vehicles
with all-wheel drive r=;, page 289, Snow
chains .
