power steering fluid AUDI S6 2008 Owners Manual

& WARNING
Although the ABS is very effective, always remember that braking
capability is limited by tire traction. Always adjust your driving
speed according to the road and traffic conditions. Do not let the
extra safety afforded by the ABS tempt you into taking extra risks.
The ABS cannot overcome the laws of physics.
[ i] Tips
• If ABS is not functioning properly, a warning light will come on .
See
=> page 22.
• If a fault occurs in the ABS , the EDL is also not functioning. This
is indicated by the ABS warning light. •
Brake assistant
The brake assistant is designed to achieve the optimum
braking effect.
The brake assistant helps to increase the effective braking power
and thus to achieve a shorter stopping distance . If the driver
presses the brake pedal very quickly, the brake assistant automati ­
cally boosts the braking force to the maximum level, up to the point
where the anti-lock brake function (ABS) intervenes to stop the
wheels from locking. You should then keep the brake pedal pressed
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.
In vehicles with Adaptive Cruise Control* (ACC), the distance to the
vehicle ahead is continuously calculated using a radar sensor,
within the limits of the system=>
page 135. If the radar system
detects a short distance to the vehicle ahead, the brake system
exerts a small braking force to reduce the brake response time in

case of braking. In this way, the brake application can be quickened
and
the stopping distance reduced.
& 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.
n
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 wheel will 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 still 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 wheel at
low speeds (for example when parking), -more effort will be
required than usual.

• Be aware of the different than usual steering response and
adj ust you r steer ing for ce accordingly.
• Have the problem checked and set right by an Audi dealer as
s o on as possible .
[ i ] Tip s
• When th e 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 hydrau lic
fluid if you keep ho lding the steering wheel turned all the way. This
is like ly to damage the power steering system.
• If the power steering system should fail entirely, or if the engine
is not running (for example, while being towed), you wil l 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 func ­
tioni ng properly, contact your authorized Audi dealer immediately.
• The power steering system requires a specially formulated
hydraulic fluid . The power steering reservoir is the one located most
forward on the left side of the engine compartment~
page 298. The
correct fluid level in the reservoir is important for proper func ­
tioning of the power steering.
App lies to vehic les: with A ll Wheel Dr ive
Dr iving with your quattro®
With All Wheel Drive, all four wheels are driven.
Gen era l i nfo rm ati on
With All Wheel Drive, power is d istr ibuted to all four whee ls. Th is
happens automatica lly depending on your driving style and the
road conditions at the time. See also ~
page 259, "Electronic differ ­
entia l lock (EDU".
Wint er tir es
When driving in the winte r, your vehicle with All Wheel Drive has an
advantage, even with regular tires. In winter road conditions it may
be advisable to mount winter tires (or all -season tires) for improved
driveability and braking: these tires must be mounted on
a ll fou r
wh eel s.
See also ~ page 329, "Winter tires".
Tire chains
Where tire chains are mandatory on certain roads, this normally
a lso app lies to veh icles with A ll Wheel Drive~
page 330, "Snow
chains".
R epl acing w hee ls/t ires
Vehicles with All Wheel Drive must always have tires of the same
size. Also avoid tires with different tread depths . For details see
page ~
page 325, "New tires and replacing tires and wheels" .
Off-R oa d dri ving?
Your Audi does no t have enough ground c learance to be used as an
off -road vehic le. It is therefore best to avoid rough tracks and
uneven terrain as much as possible . Also refer to~
page 269.
& WARNING
Always a djust yo ur driving to r oad and traffi c condition s. Do not
let the e xtr a s afet y affor ded b y All Whee l Dri ve tempt you into
taking extr a risks.
• Although the All Wheel Dr ive i s very effe ct ive , a lwa ys
r e member that braking capacity i s limited b y tire trac tion. You
s hould therefore not d riv e at e xcess iv e speed s on icy or slipp ery
road surfaces .
• On we t road surf aces, be care fu l no t to d riv e t oo fas t beca use
