2015 AUDI S3 power steering

190 Smart Technology
Steering r ecommendat ion
The ESC helps to stabilize the vehi cle by
changing the steering torque.
Select ive wh eel torqu e co ntrol
Select ive wheel torque control is used when
driving on curves . The front wheel on the in ­
side of the curve or both wheels on the inside
of the curve are braked selective ly as needed.
Th is a llows more precise driv ing in c urves.
Automatic post -collision braking system
The "Automatic post-collision braking system"
can he lp to reduce the risk of sliding and of
other coll is ions after an acc ident. If the airbag
control mod ule detects a collision above acer­
tain vehicle speed, the vehicle is braked by the
ESC.
The vehicle does not brake automatically if:
- the driver presses the accelerator pedal , or
- the braking fo rce genera ted by the pressed
brake pedal is greater than the braking force
that would be initiated by the system, or
- the ESC, the brake system or the vehicle
electrical system are not functioning .
A WARNING ,.
- The ESC and its integrated systems can­
not overcome the lim its posed by natural
physical laws. This is especia lly impor­
tant on s lippery or wet roads. If the sys-
Switching on /off
terns begin acting to stabilize your vehi­
cle, you should immediately a lter your
speed to match the road and traffic con­
ditions . Do not let the increased safety
provided tempt you into taking r isks .
This could increase your risk of a co lli­
sion .
- Please note the r isk of a coll is ion increas­
es when driving fast, especially through
curves and o n slippe ry or wet roads, and
when dr iv ing too close to objects ahead.
The ESC and i ts integrated systems can­
not a lways p revent collisions -there is
still a risk of accidents!
- Press the acce lerator pedal caref ully
when acce lerating on even, slippery sur­
faces such as ice and snow. The drive wheels can spin even when these control
systems are installed and this can affect
driving stability and increase the risk of a
coll is io n.
(D Tips
- ABS and ASR only function correctly
when all four wheels are equ ipped w ith
identical t ires . Different t ire sizes can
lead to a reduction in engine power.
- You may hear noises when the systems
descr ibed are working .
- If the
DJ or [IJ indicator light appears,
there may be a malfunction¢

E SC turns on automatically when you start the engine .
Fig. 1 50 Upper c ente r conso le : ESC but to n
The ESC is designed to funct ion in levels . De­
pending on the level that is selected, the sta­
bilization funct io n of the ESC is lim ited or
swit ched off . The amoun t of stabilization con ­
tro l will differ depending on t he level.
In the follow ing unusual situations it may
make sense to switch the ESC sport mode on
to allow the wheels to sp in:
- Rocking the vehicle to free it when it is stuck
- Driving in deep snow or on loose ground

the brakes. If you need to brake addit ion ­
ally, bra ke in intervals and not continu­
ously.
(D Tips
- If the brake boos ter is not wor king, you
must p ress the brake pedal with much
more force t hen no rma l.
- If yo u retrof it your vehicle with a front
s po ile r, wheel covers or similar items,
make sure that the air f low to the front
whee ls is not interrupted. Otherwise the
brake system can become too hot.
Electromechanical
steering
The elec tromechanical steering suppor ts the
driver's s teering movements .
Powe r stee ring adapts electronically based o n
the veh icle speed.
The vehicle still has full stee ring fu nctionality
if the powe r steering fails o r whe n the eng ine
i s stopped (towi ng). To s teer, yo u must app ly
m uc h mo re fo rce than usual.
Indicator lights and messages
• Do not drive vehicle: steering defective
If th is in dicator lig ht tu rns on and stays on
and this message appears, the power steering may have fa iled.

ALL wheel drive
(quattro)
App lies to vehicles: wi th all wheel drive
In all wheel drive, all four wheels are pow­
ered.
General information
In all whee l dr ive, the dr iv ing power is divi ded
between all fo ur whee ls. Thi s happens auto ­
matically depending on yo ur driv ing behavior
as well as the current road conditions. Refer
to
¢ page 189, Electronic stabilization con­
trol (ESC) .
The all wheel drive concept is designed for
high eng ine power. Your veh icle is except ion­
a lly powerfu l and has excellent driving charac­
te ristics both under normal driv ing cond itions
and on snow a nd ice. Always read and follow
safety precaut ions¢ .&.. ..,.

-If you notice unusual vibra­tion or if the vehicle pulls to one side when driving, al­
ways stop as soon as it is safe to do so and check the
wheels and tires for dam­ age.
(D Note
-Please note that summer and winter tires are de­
signed for the conditions
that are typical in those sea­
sons. Audi recommends us­ing winter tires during the
winter months. Low tem­ peratures significantly de­
crease the elasticity of
summer tires, which affects
traction and braking ability.
Tires and wheels 235
If summer tires are used in
very cold temperatures, cracks can form on the tread bars, resulting in perma­
nent tire damage that can
cause loud driving noise and unbalanced tires. Audi is not
responsible for this type of
damage.
-Burnished, polished or chromed rims must not be used in winter road condi­
tions. The surface of the
rims does not have suffi­
cient corrosion protection
for this and could be perma­
nently damaged by road salt
or similar substances.

Glossary of tire and loading terminology
Accessory weight
means the combined weight (in
excess of those standard items
which may be replaced) of auto­ matic transmission, power
steering, power brakes, power
windows, power seats, radio, and heater, to the extent that
these items are available as fac­
tory-installed equipment (whether installed or not).
Aspect ratio
means the ratio of the height to
the width of the tire in percent. Numbers of 55 or lower indi­
cate a low sidewall for im­ proved steering response and
better overall handling on dry
pavement.
