2011 AUDI R8 SPYDER wheel torque

as a pulsing motion of the brake pedal, ac­
companied by some noises. In order for ABS
to be able to operate optimally in th is range,
you must keep the brake pedal depressed -
never "pump the brakes" . You should not ex­
pect that braking d istances w ill be
shortened
under all circumstances with ABS . Braking dis­
tance may even be slightly
longer, for exam­
p le on gravel or wi th fresh snow on a slippery
surface .
If a sign ificant
speed differential between the
d rive wheels on one axle is determined (for
examp le, on a su rface that is s lippery
on one
side),
the EDS brakes the spinn ing whee l and
transfers power to the other drive whee ls.
This is done up to a speed of about 60 mph (100 km/h) . Noises from the brake system
signal that whee l spin is being controlled.
I f one whee l spins when starting from a com­
p lete stop because o f a different grip (for ex­
ample , one wheel o n ice), keep your foot
hard
on the accelerator until the veh icle starts to
move.
If the wheels spin , ASR wi ll automatically re­
duce engine torque and match power to road
surface conditions .
Switching on Sport mod e
In specific driving situations (e.g. Launch Con ­
trol), you swi tch ASR and ESP to Sport mode
by pressing the
[!I button once . The indicator
light
11 illuminates and ESP sport -Wa rni ng!
Restric ted stab ility
appears . "Slip" is matched
to the speed. You should do this only if your
driving skill and traffic cond it ions permit .
Switching ASR /ESP off
In certain sit uations (e .g . in deep snow, on a
l oose surface, o r when rocking the vehicle
free), switch ASR and ESP off by pressing the
[ill button for more than 3 seconds. The ind ica­
tor light
I) illuminates and ES P sw itc hed off -
Warning! R estricted stability
appears . You
should do th is only if your driving skill and
traffic cond itions pe rmit .
Int ellig ent technolog y 151
Switching ASR /ESP on
Activate ASR/ ESP by p ressing the [!I button
again. The message
ESP on appears in the d is­
play briefly.
Brake overheating
So that the disc b rake on a b raked wheel does
not overheat, the EDS switches off automati­
ca lly if there is un usua lly severe loa ding at
th is wheel. The vehicle is st ill drivable and has
the same properties as a vehicle wit hout EDS .
As soon as the brake has cooled down, EDS
swi tches on aga in automatically.
A WARNING
- Even ESP, ABS, EDS and ASR cannot over ­
come the laws of physics . You should
keep this in m ind in particular on an icy
or wet road. If the systems intervene,
you shou ld adjust your speed immediate­
ly to road and traff ic conditions . Do not
be tempted by the increased safety pro­
vided to take risks -you risk having an
accident.
- Please keep in mind that the r isk of an
accident is i ncreased by driving too fast,
pa rti cularly in corners and on icy or wet
ro ads, and by drivi ng too close to the ve­
hicle ahead . Even ES P, ABS, E DS and ASR
cannot eliminate the increased risk of
having an accident.
-Apply the throttle ca re fully when accel ­
erating on a consistently s lippery sur­
face, e.g. on ice and snow . The drive
wheels can spin in spite of the EDS and thereby affect vehicle stability -you risk
having an accident .
- Please note that when ASR or ESP/ASR is
deactivated, the drive wheels can spin on
icy and slippery roads and the veh icle can
break away -the re is a risk of skidd ing!
(D Tips
- In the event of a defect in the rear spoil-
er system or in Audi magnet ic ride, it can
happen that ASR and ASR/ESP cannot be .,.

the wheel bolts. These are available from au­
thorized Audi dealers.
A WARNING
Using the wrong snow chains for your vehi­
cle or installing them incorrectly can in­
crease the risk of loss of control leading to
serious personal injury.
- Snow chains are available in different
sizes. Always make sure to follow the in­
structions provided by the snow chain
manufacturer .
- When driving with snow chains, never
drive faster than the speed permitted for
your specific snow chains.
- Always observe local regulations.
- Remove snow chains before driving on
roads not covered with snow to avoid
damaging tires and wearing the snow
chains down unnecessarily.
- Snow chains, which come into direct con­
tact with the wheel rim, can scratch or
damage it. Therefore, make sure that the
snow chains are suitably covered . Check
the position of the snow chains after
driving a few yards and correct if neces­
sary. Follow the instructions from the
snow chain manufacturer when doing so.
(D Tips
Where snow chains are mandatory oncer­
tain roads, this normally also applies to ve­
hicles with all-wheel drive.
Wheel bolts
Wheel bolts must always be tightened to the
correct torque.
The design of wheel bolts is matched to the
factory installed rims. If different rims are fit­
ted, the correct wheel bolts with the right
length and correctly shaped bolt heads must
be used. This ensures that wheels are fitted
securely and that the brake system functions
correctly .
Tires and wheels 205
In certain circumstances, you may not use
wheel bolts from a different vehicle -even if it
is the same model
r:!> page 211.
A WARNING
Improperly tightened or maintained wheel
bolts can become loose causing loss of
control, a collision and serious personal in­
jury.
- Always keep the wheel bolts and the
threads in the wheel hubs clean so the
wheel bolts can turn easily and be prop­ erly tightened.
- Never grease or oil the wheel bolts and
the threads in the wheel hubs. They can
become loose while driving if greased or
oiled, even if tightened to the specified
torque.
- Only use wheel bolts that belong to the
rim being installed.
- Never use different wheels bolts on your
vehicle.
-Always maintain the correct tightening
torque for the wheel bolts 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
cle is moving.
If the tightening torque is
too high, the wheel bolts and threads
can be damaged and the wheel can be­
come loose.
(D Note
The specified torque for the wheel bolts is
90 ft lb (120 Nm) with a tolerance of ± 7 .4
ft lb( ± 10 Nm). Torque wheel bolts diago­
nally. After changing a wheel, the torque
must be checked as soon as possible with a
torque wrench -preferably by an author­
ized Audi dealer or qualified workshop.
Low aspect ratio tires
Your Audi is factory-equipped with low aspect
ratio tires. These tires have been thoroughly
tested and been selected specifically for your model for their superb performance, road feel
and handling under a variety of driving

.,. Close your grip around the
end of the
wrenc h handle fo r maximum torque and
turn each wheel bolt
clockwi se u nti l it sits
t ight.
H ave the
tightening torque of the whee l bolts
checked as soon as possible with a torque
wrench . It shou ld be 120 Nm.
Chec k the
tire pre ssure as soon as possible.
Return the vehicle tool kit to its proper place.
A WARNING
Loose ning t he wheel bo lts is prohib ited;
da nger of an accident!
@ Tips
- Never try and use the hexagona l socke t
i n the handle of the screwdr iver to loos­
en or tighten the w heel bolts.
- If yo u have dete rm ined t hat wheel bolts
a re cor roded and difficult to t urn, the
bo lts must be rep laced befo re checking
the to rque.
- Unti l the tig hte ning torque is checked,
d rive at redu ced speeds as a pre caution.
Notes on wheel change
Pl ease read the information¢ page 199, New
tires and replacing tires and wheels,
if you are
going to use a spare tire which is different
from the tires on your veh icle.
Afte r you change a tire:
- Check the tire pressure on the spare imme­
dia tely after mounting.
- Have the whee l bolt t ightening torque
chec ked w ith a torq ue wrench as soon as
poss ible by your author ized A udi dealer or a
qu alified service sta tion.
1 ) You need th e appropr iate adapter to tighte n the a nti­
t h eft wheel bolts
c:, page 216.
What do I do now? 219
- With stee l and alloy whee l rims, the whee l
bolts are correctly tightened at a torque of
90 ft lb (120 Nm) .
- If you notice while changing a tire that the
wheel bo lts are corroded and difficu lt to
turn, then they should be rep laced before
you check the tightening torque.
- Replace the flat tire with a new one and
have it installed on your vehicle as soon as
possible. Remount the wheel cover.
Until then , d riv e with e xtra care and at re­
duced speeds.
A WARNING
- If you are going to equ ip your vehicle
with tires or rims which differ from those
which were facto ry installed, then be
sure to read the information ¢
page 199,
New tires and replacing tir es and
wheels.
- Always sto re the tools secu rely in lug­
gage compartment. Othe rwise, in a n ac­
cident o r su dden maneuver they cou ld fly
forwdrd, CciU5ing injury to pd55enger5 in
the vehicle.
