2016 AUDI S8 torque

In extreme cases, EDL automatically switches off
to help keep the brake on the braked wheel from
overheating. EDL w ill switch on aga in a utomati­
cally when conditions have returned to normal.
Ste ering recommendat ion
The ESC helps to stabilize the ve hicle by chang ing
the s teering torque .
I n vehicles with dynamic steering*, ESC also
h e lps to s tabilize the stee ring in critical s itua­
tions.
Selective wh eel torqu e control
Select ive whee l torque control is used when driv­
in g on curves . T he front wheel on the inside of
the cu rve or both wheels o n the inside of the
curve are br aked selec tively as needed . This al ­
l ows more precise driv ing in curves . The applica­
b le system may not activate when driving in wet
or snowy conditions.
Automatic post-collision braking system
The "Automatic post-co llision bra king system"
can help to reduce the ris k of slid ing and of other
coll is ions after an accident. If the airbag contro l
module detects a col lision above a certain vehicle
speed, the vehicle is b raked by t he ESC.
The vehicle does not b rake automatica lly if :
- the driver p resses the accelerator pedal, or
- the braking force generated by the pressed
brake pedal is greate r than the brak ing force
that wou ld be initiated by the system, or
- the ESC, the brake system or the vehicle electri ­
ca l system are not f unction ing .
Sma rt Technology
A WARNING
- The ESC and its integrated systems cannot
overcome the limits posed by natural physi­
cal laws . This is especia lly important on s lip­
pe ry o r we t roads .
If the systems beg in act­
i n g to stab iliz e your ve hicle, yo u should im­
mediately change yo ur speed to ma tch the
road and traffic con dit ions . Do not let the
increased safety provided by these systems
tempt you to take r isks. Do ing so will in­
crease the r isk of a loss of vehicle contro l,
coll is ion and serious pe rsonal in juries.
- Always adapt your speed to road, traffic and
weather conditions. The risk of losing con­
trol of the vehicle increases when driving too fast, especially through curves and on
slippery or wet roads, and when driving too
close to vehi cles up ahead. The ESC and its
i n teg ra ted systems ca nnot alw ays preven t
coll is io ns -the re is s till a risk of accide nts!
- Always accelerate w ith specia l care on even,
smooth s urfaces su ch as those that are wet
or covere d wi th ice and snow. The d rive
whee ls can spin eve n wit h these assistance
systems that cannot always help to reduce
the risk of loss of vehicle contro l.
(D Tips
-ABS a nd ASR only wo rk cor rec tly when all
four wheels a re equipped wi th identi cal
tires. Diffe rent tire s izes can lead to a red uc­
tion i n engine power .
- You may hear noises when the systems de ­
scribed are working .

Depending on the equipment, the vehicle tool kit
may be located under the spare tire under an ad­
d itional cover or in the too l box. The position of
the vehicle jack* may vary.
A WARNING
Improper use of the vehicle jack can cause se­
r ious personal injuries.
- Never use the screw driver hex head to
t ighten wheel bolts, since the bolts cannot
attain the necessary tighten ing torque if you
use the hex head, potentia lly causing an ac­
c ident.
- The factory-supplied jack is intended on ly
for your vehicle model. Under no circum­
stances should it be used to lift heavy
vehicles or other loads; yo u risk injuring
yo urself.
- Never start the engine whe n the vehicle is
raise d, which could ca use a n accident.
- Support the veh icle secure ly with appropr i­
a te stands if wor k is to be perfo rmed u nder ­
neath the veh icle; otherwise, the re is a po­
tential risk for in jury.
- Never use the jack s upplied with your Audi
on another vehicle, particularly o n a heav ier
one. The jack is only suitab le for use on the
vehicle it came wit h.
@ Tips
The vehicle j ack* in your vehicle is mainte ­
nance -free.

Space-saving spare tire (compact spare
tire)
Applies to: vehicles with space-saving spare tire
The spare tire/wheel is located in the luggage
compartment under the cargo floor cover . It is
intended for short-term use only.

Using the spare tire (compact spare tire )
The compact spare tire is on ly intended for emer­
gencies until you can reach a repair shop . Rep lace
it as quick ly as poss ible with a standard wheel
and tire.
T here are some restr ictions on the use of the
compact spare tire. The compact spa re tire has

Emergency assistance
After changing a wheel
A wheel change is not complete without the do­
ing the following .
• Always store the vehicle tool kit, the jack* and
the replaced tire in the luggage compartment
<=>page 135.
• Check the tire pressure on the spare wheel im­
mediate ly after mounting it.
• As soon as possible, have the
tightening tor­
ques
on all wheel bolts checked with a torque
wrench. The correct tightening torque is 90 ft
lb (120 Nm).
• Have the flat tire
replaced as soon as possible.
@ Tips
- If you notice that the whee l bolts are cor­
roded and difficu lt to turn while changing a
tire, they should be replaced before you
check the tightening torque .
- Drive at reduced speed until you have the
tightening torques checked.
- After changing a wheel, the tire pressure in
a ll four tires must be checked/corrected and
the tire pressure mon itor ing indicator must
be stored in the MMI
c> page 255.
Decorative wheel covers
App lies to: vehicles with decorative wheel covers
The decorative wheel covers must be removed
first to access the wheel bolts .
Fig. 216 Chan gin g a w heel : Removing the whee l cover
Removing
• Insert the hook (provided with the ve hicle tool
kit) in the hole in the wheel hub cover.
• Pull off the
decorative wheel cover c> fig. 216.

Wheels with wheel bolt caps
Applies to: vehicles with wheel bo lts with caps
The caps must be removed first from the wheel
bolts before the bolts can be unscrewed .
Fig. 217 Changing a wheel: removing the wheel bo lt caps
Removing
• Push the plastic clip (provided with the vehicle
tool kit) over the whee l bolt cap until the inner
retainers on the clip align with the edge of the
cover.
• Remove the cap with the
plastic clip (vehicle
tool kit)
<=> fig. 217 .
Refitting
• Place the caps over the wheel bolts and push
them back on .
The caps are to protect and keep the wheel bolts
clean.
Loosening and tightening the wheel bolts
The wheel bolts must be loosened before raising
the vehicle.
Fig. 218 Chang ing a wheel: loosening the wheel bo lts

After you change a tire:
- Check the tire pressure on the spare immedi­
ately after in stallation.
- Have the wheel bolt tightening torque
checked with a torque wrench as soon as pos­
s ible by your authorized Audi dealer or a
qualified servi ce stat ion .
- With steel and alloy wheel rims, the wheel
bolts are correctly tightened at a torque of 90
ft lb (120 Nm).
- If you notice that the wheel bolt s are corroded
and difficult to turn while changing a tire,
they should be replaced before you check the
tightening torque .
- Replace the flat tire with a new one and have
it installed on you r 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 equ ip your vehi cle w it h
t ir es o r rims which differ f rom those which
we re factory installed, then be s ure to read
the info rmat io n ¢

even a flat tire and the jack and tool kit a re
prope rly secured in the luggage com part ­
me nt and are not loose in t he passenger
compar tment.
- In an accident o r sudden maneuver they
cou ld fly forward, inju ring anyone in the ve­
hicle.
- Always store damaged whee l, jac k and too ls
sec urely in the luggage co mpartment . Oth ­
erwise, in an accide nt or sudd en man euver
