194 Intelligent technology
been damaged, the brake pedal must be
pressed considerably harder to make up
for the lack of booster assistance.
Servotronic ® -
advanced power
steering system
The power steering systems use the power of
the running engine to allow precise steering
with little effort .
The advanced Servotronic® power steering
system senses the road speed and e lectroni
cally adjusts power assistance to prov ide com
fortable and safe steering response exactly
matched to the veh icle speed.
Power steering w ill not work if the eng ine is
off . As a result, the steering whee l wi ll be hard
to turn.
The power steering fluid level is checked dur
ing the scheduled maintenance serv ices.
([) Note
If there is an electronic malfun ct ion, ser
votronic
w ill still f unction like a conven
tional power steer ing system, providing a
constant steering support force that is no
longer proportionate to the vehicle speed.
This is most noticeab le when turning the
steer ing whee l at low speeds (for examp le
when parking), - more effo rt will be re
qui red than usua l.
- Be aware of the different than usual
stee ring response and adjust yo ur stee r
i ng fo rce accord ingly.
- Have the p roblem checked and set rig ht
by an Aud i deale r as soon as possib le.
(D Tips
- When the engine is runn ing, never hold
t h e steer ing whee l turned all the way to
the right or to the left for longer than 15
se conds. The power steer ing p ump w ill
ove rhe at the hydr aulic flu id if you keep
ho ld ing the steering whee l turned all the way
. This is likely to damage the power
steering system .
- If the powe r steering system sho uld fai l
entirely, o r if the engine is not runn ing
(for examp le, whi le being towed), you
w ill sti ll be able to steer the veh icle.
However,
considerably more effort will
be required to do so.
- If the power steering system sho uld
have a leak, or is not functioning proper
ly, contact your author ized Audi dealer
immed iately.
- The power steering system requ ires a
specially fo rmu lated hydraulic fluid. The
powe r stee ring fluid reservoir is locat ed
in the engine compartment

T he corre ct fl uid level i n the reservoir is

powe r stee ring .
Driving with your

en .
Gen eral information

Winter tires
When driving in the winter, yo ur vehicle with
All Wheel D rive has an advantage, even w ith
r egular tires . In wi nter road conditions it may
be advisable to mount winter tires (or all-sea
son tires) for improved driveability and brak
i ng : these tires must be mo unted o n
