power steering AUDI RS7 SPORTBACK 2015 User Guide

192 Intelligent technology
overheat, premature wear and increased
stopp ing distance.
- Under certain climatic and operating
condit ions such as passing through wa­
ter, driving in heavy ra in or after wash ing
the vehicle, the effect iveness of the
brakes can be reduced. In winter, ice ca n
accumulate on the brake pads, linings ,
discs and d rums . Carefully apply brakes
for a test . B rakes wi ll dry a nd ice coat­
ings will be cleaned off after a few c are­
f ul brake app lications .
- Dr iv ing fo r an ex tende d pe riod of time on
salt-covere d roads w ithout us ing yo ur
brakes can also affect braking efficiency.
Clean off accumulated salt coating from
bra ke discs and pads w ith a few caref ul
brake applicat ions.
- If you damage the front spoiler, or if you
install a different spoiler, be sure the air
flow to the front brakes is not obstruct­ ed. Otherwise the brake system could
over heat reducing the effectiveness of
the ent ire brake system .
- Failure of one brake c ircuit will impair
the braking capability res ulting in an in­
creased stopp ing distance. Avoid driv ing
the vehicle and have it towed to t he near­
est Aud i dea le r o r q ualified w ork sho p.
- Never let the vehicle ro ll to a stop w ith
the e ngine shu t off.
- If the brake booster is not working, the
brake pedal must be p ressed conside ra­
bly harder to make up for the la ck of
booster assistance.
Electromechanical
power assist, dynamic
steering
The electromechanical power assist helps the
driver when steering .
Power stee ring adapts electronically based on
the vehicle speed .

228 Tires and wheels
-If you notice unusual vibra­
tion 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.
0 Note
-Please note that summer and winter tires are de­
signed for the conditions
that are typical in those sea­
sons. Audi recommends us­
ing winter tires during the
winter months. Low tem­ peratures significantly de­
crease the elasticity of
summer tires, which affects
traction and braking ability. 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.
