2015 AUDI RS5 COUPE wheel torque

Smart Technology
In extreme cases, EDL automatically switches off
to help keep the brake on the braked wheel from
overheating. EDL will switch on again automati­
cally when conditions have returned to normal.
Steering recommendation
The ESC helps to stabilize the vehicle by changing
the steering torque.
I n vehicles with dynamic steering*, ESC also
he lps to stabilize the steering in critical situa­
tions .
Selective wheel torque control
Select ive wheel torque control is used when driv­
ing on c urves . The front wheel on the inside of
the curve or both whee ls on the inside of the
curve are braked selectively as needed. This al­
lows more precise driving in curves . Th e applica­
b le system may not activate when driving in wet
or snowy conditions .
A WARNING
- The ESC and its integrated systems cannot
overcome the laws of physics. This is espe­
c ially important on slippery or wet roads. If
the systems beg in acting to stabilize your
vehicle, you should immediately change
your speed to match the road and traffic
Switching on/off
conditions . Do not let the increased safety
provided by these systems tempt you to
take risks. Doing so will increase the risk of a
loss of vehicle control, collision and serious
personal injuries.
- Always adapt your speed to road, traffic and
weather conditions. The risk of losing con­
trol of the vehicle increases when dr iving
too fast, especially through curves and on
slippery or wet roads, and when driv ing too
close to vehicles up ahead. The ESC and its
integ rated systems cannot always prevent
collisio ns -there is sti ll a risk of accidents!
- Always accelerate with special care on even,
smooth surfaces such as those that are wet
or covered with ice and snow. The drive
wheels can spin even with these assistance
systems that cannot always help to reduce
the risk of loss of vehicle control.
@ Tips
-ABS and ASR only work correctly when all
four wheels are equ ipped w ith identical
t ires. Different tire s izes can lead to a reduc­
t ion in engine power.
- You may hear noises when the systems de­ scribed are working.
ESC turns on automatically when you start the engine .

The ESC is designed to function in levels. Depend­
ing on the level that is selected, the stabilization
function of the ESC is limited or switched off. The

pending on the level.

Smart Technolog y
-If y ou dama ge the front spo iler, or if you in ­
sta ll a di fferent spoile r, be sure the air flow
to the front brakes is not obstructed . Other ­
wise the brake system co uld overheat reduc­
ing the effectiveness o f the enti re brake sys­
tem .
- Failure of one brake c ircuit will impair the
braking capab ility r esult ing in a n increased
stopp ing distance. Avoid driving the veh icle
and have it towed to the nearest au thorized
Audi de aler or qualified workshop.
- Never let the vehicle ro ll to a stop with the
engine shut off .
-If the brake booster is not work ing, the
brake pedal must be pressed considerably
harder to make up for the lack of booste r as­
sistance .

tion repaired as soon as possible by an author­ ized A udi dealer or qualified wo rkshop -risk
of accident!
@ Tips
- If the . or ':rfl indicator light only stays on
for a sho rt time, you may cont inue driving.
- The dynamic steering* stab ility systems are
not availab le in the event of a system mal­
function.
- For add itiona l information on dynamic
steering*, refer to~ page 101.
Driving with your quattro
With all-wheel drive, all four wheels are driven .
General information
With all-wheel drive, power is distributed to all
four wheels . This happens automatically depend­
i ng on your driving style and the road conditions
at the t ime . See also ~ page 169.
A center d ifferential distributes the driving power
variably to the front and rear axle. It works to­
gether w ith select ive whee l torque control, which
activates w hen d rivi ng throug h curves
~ page 170 . With the spo rt diffe rential*, power
dist ribution to the rear wheels is variab le and can
be adjusted with drive select~ page 101.
The all-whee l dr ive concept is des igned for hig h
engine power . Yo ur vehicle is exceptiona lly pow­
e rfu l and has excellen t drivi ng cha racte rist ics
both unde r normal d riving condi tions and o n
snow and ice . Always read and follow sa fe ty pre-
ca utions ~& .

A WARNING 1=
You or your passengers cou ld be injured while
chang ing a wheel if you do not follow these
safety precautions:
- If you have a flat t ire, move a safe distance
off the road . Turn off the engine, turn the
emergency flashers on and use other warn­
ing devices to alert other motorists.
- Make sure that passengers wait in a safe
place away from the vehicle and well away
from the road and traff ic.
- To help prevent the veh icle from mov ing
sudden ly and possibly slipping off the jac k,
always fully set the pa rking brake and block
the whee l diagona lly opposite the w heel be­
ing changed with the folding chocks or oth ­
er objects. When one front wheel is lifted
off the ground, placing the Automatic Trans­
mission in "P" (Park) will
not prevent the ve ­
hicle from moving.
- Before you change a wheel, be sure the
ground is level and firm. If necessary, use a
sturdy board under the jack.
- Always store the vehicle tool kit, the jack *
and the replaced tire in the luggage com­
partment

Tires with unidirectional tread design
Tires with unidirectional tread design must be
mounted with their tread pattern pointed in the
right direction.
Using a replacement tire with a tread pattern
intended for use in a specific direction
When using a replacement tire with a tread pat·
tern intended for use in a specific direction,
please note the following:
- The direction of rotation is marked by an
arrow
on the side of the tire .
-If the replacement tire has to be installed i n
the inco rrect direction, use the tire only tempo·
rarily since the tire will not be able to achieve
its optimum performance characteristics with
regard to aquaplaning, noise and wear.
- We recommend that you pay particular atten·
tion to this fact during wet weather and that
you adjust your speed to match road condi­
tions .
- Replace the flat tire with a new one and have it
installed on your vehicle as soon as possible to
restore the handling advantages of a unidirec­
t ional tire.
Notes on wheel changing
Please read the information ¢ page 203, New
tires or wheels
if you are going to use a replace­
ment tire which is different from the t ires on your
vehicle.
After you change a tire:
- Check the tire pressure on the replacement
tire immediately after installation.
- Have the wheel bolt tightening torque
checked with a torque wrench as soon as pos­
sible by your authorized Audi dealer or quali­
fied workshop.
- With steel and alloy wheel rims, the wheel
bolts are correctly tightened at a torque of 90
ft lbs . (120 Nm).
- If you notice that the wheel bolts are corroded
and difficult to turn while changing a tire,
they should be replaced before you check the
tightening torque.
Emergency assistance
- Replace the flat tire with a new one and have
it installed on your vehicle as soon as possi­
ble. Remount the wheel cover.
Until then, drive with extra care and at reduced
speeds.
_& WARNING
- If you are going to equip your vehicle with
tires or rims which differ from those which
were factory installed, then be sure to read
the information¢
page 203, New tires or
wheels.
- Always make sure the damaged wheel or
even a flat tire and the jack and tool kit are properly secured in the luggage com part·
ment and are not loose in the passenger
compartment.
- In an accident or sudden maneuver they
could fly forward, injuring anyone in the ve·
hide.
-Always store damaged wheel, jack and tools
securely in the luggage compartment. 0th·
erwise, in an accident or sudden maneuver
they could fly forward, causing injury to pas­
sengers in the vehicle.
(D Note
Do not use commercially available tire seal·
ants. Otherwise, the electrical components of
the tire pressure monitoring system* will no
longer work properly and the sensor for the
tire pressure monitoring system* will have to b e replaced by qualified workshop.
