until the vehicle has braked to the required speed. The brake assis­
tant switches itself off as soon as you release the brake pedal.
The brake assistant will not be operative if there is a malfunction in
the ABS.
& WARNING
Please remember that the accident risk always increases if you
drive too fast, especially in corners or on a slippery road, or if you
follow the vehicle ahead of you too closely. Increased risk of an
accident cannot be compensated for even by the brake assistant,
so always maintain a safe speed. •
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 system senses the road
speed and electronically adjusts power assistance to provide
comfortable and safe steering response exactly matched to the
vehicle speed.
Power steering will not work if the engine is off. As a result, the
steering whee l wil l be hard to turn.
The power steering fluid level is checked during the scheduled
maintenance services.
0 Note
If there is an electronic malfunction, servotronic will sti ll function
like a conventional power steering system, providing a constant
steering support force that is no longer proportionate to the vehicle
speed. This is most noticeable when turning the steering whee l at

low speeds (for examp
le when parking), -more effort will be
requ ired than usual.
• Be aware of the different than usual steering response and
adjust your steering force accordingly .
• Have the problem checked and set right by an Audi dealer as
soon as possible.
[ i ] Tips
• 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 steering pump will overheat the hydraulic fluid
if you keep holding the steering whee l turned a ll the way. This is
likely to damage the power steering system.
• If the power steering system shou ld fail entire ly, or if the engine
is not running (for examp le, while being 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 shou ld have a leak, or is not func ­
t ioning properly, contact your authorized Audi dealer immediately.
• The power steering system requires a special ly formulated
hydraulic fluid. The power steering reservoir is the one located most
forward on the left side of the engine compartment=>
page 310. The
correct fluid level in the reservoir is important for proper func­
tioning of the power steering .•
