The brake assistant will not be operative if there is a malfunct io n in
t he ABS.
& WARNING
Plea se remember that the accident ri sk a lwa ys increa se s if you
d riv e too fast , especially in corne rs or on a slippery road , or if you
follow the vehi cle ahead of you too closely . In cre ased ri sk of an
accident cannot be compensated for e ven by the brake ass istant,
so always maintain a safe speed. •
Servotronic® - advanced power
steering system
The power steering systems uses th e power of the
running engine to allow precise steering with little effort.
Th e advanced Servotronic ® power steeri ng system senses the road
speed and electronically ad justs power assistance to provide
c omfortable and safe s teer ing response exa ctly matched to the
vehicle speed.
Powe r steering will not work if the engi ne is of f. As a resu lt, the
steer ing wheel will be hard to turn .
The power stee ring fluid level is checked during the sched uled main­
t enance se rvi ces.
0 Note
If the re is an ele ct roni c mal func tion, servotroni c will still f unction
like a conventional power steer ing system, prov iding a constant
steeri ng support force tha t is no lo nger propo rt iona te to the ve hicle
speed. This is most not iceab le when turn ing the steer ing wheel at low
speeds (for example when parking), -more effort will be required
than usual.
Controls and equip­ ment Safety first Vehicle operation
•
Be aware of the d ifferent than usual steering response and adjust
your stee rin g for ce acco rdi ng ly.
• Have the prob lem checked and set r ight by an A udi dea ler as soon
as possib le.
[ i ] Tips
• Whe n the eng ine is runni ng, neve r hold t he steering w hee l turned
all the way to the right or to t he left for longer than 15 seconds. The
powe r stee ring pump wi ll over heat the hydra ulic fluid if yo u keep
holding the steeri ng w heel tur ned all the way. This is likely to damage
the power steering system .
• If the power stee ring system shou ld fa il entire ly, or if the engine
is not r unning (fo r examp le, while being towed), you w ill still be a ble
to steer the vehicle. However,
considerably more effo rt will be
req uired to do so .
• If the power steering system s hou ld have a lea k, or is not func­
tioning properly, contact your authorized Au di dea ler immediate ly .
• The power steering system requ ires a specially formulated
hydra ulic fl uid. The power stee ring re se rvoir is t he one located mos t
forward o n the left side of the eng ine compa rtment=:>
page 290 . The
correct fluid leve l in the reservoir is important fo r proper f unctioning
of t he power steering. •
Dr"ving with your quattro®
