2013 AUDI RS5 CABRIOLET torque

ESC includes and/or works together with the
anti-lock brake system (ABS), brake assist sys ­
tem, anti -slip regulation (ASR) , e lectronic dif­
ferential lock (EDL), dynamic steering* and se­ lective wheel torque control*. ESC is switched
on all the time. In certa in situations when you
need less t raction, you can sw itch off ASR by
p ress ing the button
ij] Q page 178, fig . 169
or ~ page 178, fig. 170. Be sure to sw itch
ASR on again when you no longer need less
traction.
Anti -lock braking system (ABS)
ABS prevents the wheels from locking up
when braking. The veh icle can still be steered
even du ring ha rd b raking . Apply steady pres­
sure to the brake pedal. Do not pump the ped­
al. A pulsing in the brake peda l indicates that
the system is he lping you to brake the vehicle .
Brake ass ist system
The brake assist system can decrease braking
d istance.
It increases braking power when the
driver presses the brake pedal qu ic kl y in eme r­
gency situations . You must p ress and ho ld the
brake peda l until the situation is over. In
vehicles with adaptive cruise control*, the
brake assist system is more sensit ive if the
d istance detected to the vehicle ahead is too
small.
Anti- slip regulati on (ASR )
ASR reduces engine power when the drive
wheels begin to spin and adapts the force to the road condit ions. This makes it eas ier to
start, accelerate and drive up hills.
El ectronic diffe rential lock (EDL )
The ED L brakes wheels that are spinning and
transfers the drive power to the other wheels .
This function is available up to about 60 mph
(100 km/h).
I n extreme cases, ED L automatically switches
off to help keep the brake on the braked whee l
from overheating.
EDL wi ll switch on again au­
tomatically when conditions have returned to normal.
Int ellig ent technolog y 177
Dynamic steering *
On vehicles with dynam ic steering*, ESC he lps
stabilize the steering in crit ica l sit uations.
Select ive wheel torque control*
The select ive wheel torque control operates
when d riving through curves. The front wheel
on the inside of the curve o r both wheels on
the ins ide of the c urve a re bra ked select ively
as needed. This minimizes sliding in the front
whee ls and allows for more precise driv ing
through curves. The app licable system may
not act ivate when dr iving in wet or snowy con­
ditions.
A WARNING -
- ESC, ABS, ASR, EDL dynam ic steering*
and the select ive wheel torque control*
cannot ove rcome the laws of physics.
This is especially important on slippery
or wet roads.
If t h e systems beg in acting
to stabilize your veh icle, yo u should im­
mediately change your speed to match
the road and traffic conditions . Do not
let the increased safety provided by
these systems tempt you to take r isks.
Doing so will increase the risk of a loss of
veh icle contro l, collision and ser ious per­
sonal injur ies.
- Always adapt your speed to road, traffic
a nd weather conditions. The risk of Los-
ing contro l of the vehicle i ncreases when
driving too fast, espec ially through
curves and on slippery or wet roads, and
when dr iv ing too close to vehicles up
ahead. ESC, ABS, the brake assist sys ­
tem, ASR, ED L dynamic steering * and the
selective whee l torque control * cannot
prevent coll is ions.
- Always accelerate with spec ial 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 can not al­
ways he lp to red uce the risk of loss of ve­
hicle control.

';'ij Dynamic stee ring : initi alizing
If th is driver message appears and the ind ica­
tor light is flash ing on the inst rument pane l,
dynamic steering* is be ing reinitialized. Once
you start the engine after this is finished, the
steering whee l wi ll be easy to move. Re-initi­
alization m ight be necessary if the steering
wheel was moved hard to the left and r ight
while the veh icle was not moving. The display
goes out as soon as initialization is complete .
A WARNING
Have the dynamic steering* system mal­
function repaired as soon as poss ible by an
authori zed Audi dealer or any qualified
workshop -risk of accident!
@ Tips
- If the . or 1~ ij indicator light only stays
on for a short t ime, you may continue
driving.
- The dynamic steering* stability systems
are not available in the event of a system
malfunction.
- For additional informat ion on dynamic
stee ring*, refer to
c::> page 104.
Driving with your
quattro ®
With all-wheel drive, all four wheels are driv­
en.
G ene ral inform ation
W ith all -whee l dr ive, power is distributed to
all fo ur wheels. This happens automatica lly
depending on your driving sty le and the road
conditions at the time . See also
c::> page 176.
A center diffe rent ial distr ibutes the dr iv ing
power variably to the front and rear axle.
It
works together with se lective wheel torque
control, which activates when driving through
curves
c::> page 177. W ith the sport d ifferen ­
tial*, power distribution to the rear wheels is
variable and can be adjusted with drive select
<=:> page 104 .
Intellig ent technolog y 181
The all -whee l drive concept is designed for
high engine power. Your vehicle is exception­
ally powerfu l and has excellent driving charac­
teristics both under normal driv ing cond itions
and on snow and ice. Always read and follow
safety precaut ions
c::> ,&. .
Winter t ires
When driving in the winter, yo ur vehicle with
a ll-wheel drive has an advantage, even w ith
regular tires. In winter road conditions it may
be advisable to mount winter tires (or all-sea­
son tires) for improved driveability and brak ­
ing: these tires must be mounted on
a ll fou r
wheels. See also c::> page 23 7, Winter tires.
Tire chains
Where tire chains are mandatory on certain
roads, this normally also applies to veh icles
with all -wheel drive
c::> page 238, Snow
chains .
Replacing whee ls / tires
Vehicles with a ll-wheel drive must always
have tires of the same s ize. Also avoid tires
with different tread depths. For deta ils see
page
~ page 233, New tires and replacing
tires and wheels .
Off-Road driving?
Your Audi does not have enough ground clear­
ance to be used as an off-road vehicle. It is
therefore best to avoid rough tracks and un ­
even terrain as much as possible . Also refer to
~ page 184.
A WARNING
Always ad just your dr iv ing to road and t raf­
fi c condi tions. Do no t let the extra safety
afforded by all-wheel drive temp t you into
taking extra risks.
- Al tho ugh t he all-wheel drive is very ef­
fective, always remember that braking capacity is lim ited by tire traction . You
should therefore not d rive at excessive
speeds on icy or slippery road surfaces.

Wheel bolts
Wheel bolts must always be tightened to the
correct torque .
The design of wheel bolts is matched to the
factory installed r ims. If differen t rims are fit­
ted, the correct wheel bolts with the right l ength and correctly shaped bolt heads must
be used. This ensures that wheels are fitted
securely and that the brake system functions
correctly .
In certain circumstances, you may not use
wheel bo lts from a different vehicle -eve n if it
i s the same model
¢ page 266.
_&. WARNING
Improperly tig htened or maintained whee l
bolts can become loose ca using loss of
contro l, a co llision and serious persona l in­
jury.
- Always keep the wheel bolts and the threads in the wheel hubs clean so the
whee l bolts can turn easily and be prop­
erly t ightened.
- Never grease or oil the wheel bo lts and
the threads in the wheel hubs. They can become loose wh ile driving if greased or
o iled, even if tightened to the specif ied
torque .
- Only use wheel bolts that belong to the
rim being installed.
- Never use different whee ls bolts on your
vehicle .
-Always maintain the correct tighten ing
torque for the wheel bo lts to reduce the
risk of a wheel loss . If the tightening tor ­
que of the wheel bolts is too low, they
can loosen and come out when the vehi­
cl e is moving.
If the tightening torque is
too high, the whee l bolts and threads
can be damaged and the wheel can be­
come loose.
Q;) Note
The spec ified torque fo r the wheel bo lts is
90 ft lbs. (120 Nm) with a tolerance of
± 7,4 ft lbs.(± 10 Nm). Torque wheel bo lts
Tire s an d wheel s 239
diagonally. After changing a wheel, the
torque m ust be checked as soon as possi­
ble with a torque wrench -preferably by an
a uthori zed Audi dea ler or qualified work­
shop.
Low aspect ratio tires
Your Aud i is factory -equ ipped w ith low aspect
ratio tires . These tires have been tho roughly
tested and been se lected specifically fo r your
model for their superb perfo rmance, road fee l
and hand ling under a var iety o f driving cond i­
tions. Ask your authorized Audi dealer for
more details .
T he low aspect ratio of these t ires is ind icated
by a numeral of
55 or l ess in the tire's s ize
designation. The numera l rep resents the ra tio
of the tire's sidewa ll height in relation to its
tread width expressed in percentage . Conven­
tiona l tires have a he ight/w idth ratio of 60 or
more.
T he performance of low-a spe ct- ra tio tire s is
p ar tic ul ar ly se nsi tiv e to i mprop er i nfl ation
pre ssure. It is the refo re important that low
a spect ratio t ires are inflated to the specified
pr ess ure and that th e inflation pr essur e is
r e gula rly ch ecked and maintain ed. Tir e pre s­
s ure s should b e check ed at l east once a
m onth and alwa ys befo re a long trip
¢ page 228, Checking tire pressure.
What you c an do to avo id tire and rim
damage
Low aspect ratio tires can be damaged mo re
easily by impact w ith potholes, curbs, g ull ies
o r ridges on the road, pa rticularly if the tire is
u nderinflated.
In orde r to minimize the occurrence of impact
damage to the tires of your vehicle, we recom ­
mend that you observe the following p reca u­
tions:
- Always ma inta in recommended inflation
pressu res. Check your tire pressure eve ry
2,000 miles (3,000 km) and add air if neces-
sary . .., •

tance off the road . Turn off the engine,
tu rn the emergen cy flashers on and use
other wa rning dev ices to alert other mo­
torists.
- Make su re that passengers wait i n a safe
pla ce away from the vehicle and well
away from the road and traff ic.
- T o help prevent the veh icle from mov ing
sudden ly and possibly slipping off the
jack, a lways fully set the parking brake
and block the whee l diagona lly opposite
the whee l being changed with the fo ld­
ing chocks or other objects. When one
front whee l is lifted off the ground, plac­
ing the Automat ic Transmiss ion in "P"
(Pa rk) w ill
not prevent the vehicle from
moving.
- Before you change a wheel, be sure the ground is level and firm . If necessary,
use a sturdy board unde r the jack.
- Always store the vehicle tool kit, the
jack* and the replaced tire in the luggage
compartment
