2013 AUDI S8 lock

-Never mount used tires on your vehicle if
you are not sure of their "previous histo­
ry." Old used tires may have been dam­
aged even though the damage cannot be
seen that can lead to sudden tire failure
and loss of vehicle control.
- All four wheels must be fitted with radial
tires of the same type, size (rolling cir­
cumference) and the same tread pattern.
Driving with different tires reduces vehi­
cle handling and can lead to a loss of
control.
- If the spare tire is not the same as the
tires that are mounted on the vehicle -
for example with winter tires - only use
the spare tire for a short period of time and drive with extra care. Refit the nor­
mal road wheel as soon as safely possi­
ble.
- Never drive faster than the maximum
speed for which the tires on your vehicle
are rated because tires that are driven
faster than their rated speed can fail
suddenly.
- Overloading tires cause heat build-up,
sudden tire failure, including a blowout
and sudden deflation and loss of control.
- Temperature grades apply to tires that
are properly inflated and not over or un­
derinflated .
- For technical reasons it is not always
possible to use wheels from other
vehicles - in some cases not even wheels
from the same vehicle model.
- If you install wheel trim discs on the ve­
hicle wheels, make sure that the air flow
to the brakes is not blocked. Reduced air­
flow to the brakes can them to overheat,
increasing stopping distances and caus­
ing a collision.
- Run flat tires may only be used on
vehicles that were equipped with them
at the factory. The vehicle must have a
chassis designed for run flat tires. Incor­
rect use of run flat tires can lead to vehi­
cle damage or accidents. Check with an
authorized Audi dealer or tire specialist
to see if your vehicle can be equipped
Tires and wheels 263
with run flat tires. If run flat tires are
used, they must be installed on all four
wheels. Mixing tire types is not permit­
ted.
@ Note
- For technical reasons, it is not generally
possible to use the wheel rims from oth­
er vehicles. This can hold true for wheels
of the same vehicle type.
- If the spare tire is different from the
tires that you have mounted on your ve­
hicle (for example winter tires or wide
profile tires), then use the spare tire for a
short period of time only and drive with
extra care. Replace the flat tire with the
tire matching the others on your vehicle
as soon as possible.
- Never drive without the valve stem cap .
The valves could get damaged.
(® For the sake of the environment
Dispose of old tires in accordance with the
local requirements.
Uniform tire quality grading
-Tread wear
- Traction AA A B C
- Temperature ABC
Quality grades can be found where applicable
on the tire side wall between tread shoulder
and maximum section width
~ page 260,
fig. 208 .
For example: Tread wear 200, Traction AA,
Temperature A.
All passenger car tires must conform to Feder­
al Safety Requirements in addition to these
grades .
Tread wear
The tread wear grade is a comparative rating
based on the wear rate of the tire when tested
unde r contro lled conditions on a specified
government test course. •
•

If yo u have a flat tire, see notes on spa re
wheel
¢ page 260 .
P lease always remember th at w inte r ti res may
have a lower speed rating than the t ires origi­
na lly installed on your vehicle at the time it
was manufactured. Please see ¢
page 262,
Speed rating (letter code) for a list ing of the
speed rat ing letter codes and the m aximum
speed at which the tires can be driven .
The speed rating letter code( ¢
page 252) is
on the s ide wall of the tire ¢
page 260.
A WARNING
Winter tires have maximum speed limits
that may be lower than your vehicle's max­
imum speed . Always know the maximum
speed before driving off. Never drive faster
than the speed permitted for your specific
w inter t ires. This will cause damage to the
t ires leading to an acc ident and serious
personal in jury to you and yo ur passen­
gers .
& WARNING
Driving faster than the maximum speed
for which the winter tires on your vehicle
were designed can cause tire fai lure in­
cluding a blowout and sudden deflat ion,
loss of control, crashes and serious per­
sonal injuries . Have worn or damaged tires
rep laced immed iate ly .
- Winter tires have max imum speed rat ing
that may be lower than your veh icle's
maximum speed .
- Never drive faster than the speed for wh ich the winter or other tires installed
on your vehicle are rated.
A WARNING
Always adjust your d rivi ng to the road and
t raffic conditions. Neve r let t he good ac­
celeration of the winte r tires and all-whee l
drive tempt you into taking extra r is ks. A l­
ways remember:
Tire s an d wheel s 265
-W hen braking, an a ll-wheel drive vehicle
handles in the same way as a front drive
veh icle.
- Drive carefully and reduce your speed on
icy and slippery roads, even w inter t ires
cannot help under black ice conditions.
@ For the sake of the environment
Use summer tires when weather condi­
tions permit. They are quieter, do not wear
as quickly and reduce fuel consumpt ion.
Snow chains
Snow cha ins may be fitted only to the front
whee ls, and o nly to certain tire sizes . Ask your
authorized Aud i dea le r on which tire sizes
snow c hains can be used.
If you a re go ing to u se snow chains, then you
must install them on the front whee ls at
least.
The snow chains mus t have low-profile links
and must not be th icker than 0 .4 inch
(10,5 mm) , includ ing t he lock.
Remove wheel center covers and trim discs
before putt ing snow cha ins on your vehicle
¢ (D . For safety reasons cover caps must then
be fitted over the wheel bol ts . These a re ava il­
able from autho rized Aud i deale rs .
A WARNING
Usi ng the wrong snow chai ns for your vehi­
cle o r insta lling them incorrect ly can in­
crease the r isk of loss of cont ro l leading to
serious pe rsonal injury.
- Snow chains are available in different
sizes . Always make sure to follow the in ­
structions provided by the snow chain manufacturer .
- When drivi ng with snow chains never
drive faster than the speed permitted for
your specif ic snow chains.
- Always observe local regulations .

Bulbs
Replacing light bulbs
For your safety, we recommend that you hav e
your authorized Audi dealer replace burned out bulbs for you.
It is becoming increasingly more and more
difficu lt to replace vehicle light bulbs since in
many cases, other parts of the car must first
be removed before you are able to get to the
bulb . This applies especially to the light bulbs
in the front of your car which you can only
reach through the engine compartment.
Sheet metal and bulb ho lders can have sharp
edges that can cause serious cuts, and parts must be correctly taken apart and then prop­
erly put back together to help prevent break­
age of parts and long term damage from wa­
ter that can enter housings that have not been
properly resealed .
For your safety, we recommend that you have
your author ized Audi dealer replace any bulbs
for you, since your dealer has the proper tools,
the correct bulbs and the expertise.
Gas discharge lamps (Xenon lights):
Due to the high electrical voltage, have the
bulbs replaced by a qualified technician.
Headlights with Xenon light can be identified
by the high voltage sticker .
LED headlights* requ ire no ma intenance .
Please contact your authori zed Audi dealer if a
bulb needs to be replaced.
Fuses and bulbs
A WARNING
Contact with high-voltage components of
the electrical system and improper re­
placement of gas discharge (Xenon) head­
light bulbs can cause ser ious personal in­
jury and death.
- Xenon bulbs are pressur ized and can ex­
plode when being changed.
- Changing Xenon lamps requ ires the spe­
cial tra ining, instructions and equip­
ment.
- Only an authorized Audi dealer or other
qua lified workshop should change the
bu lbs in gas discharge lamps .
A WARNING
There are parts with sharp edges on the
openings and on the bulb holders that can
cause serious cuts.
- If you are uncertain about what to do,
have the work performed by an author­
ized Audi dealer or other qualified work­
shop . Serious personal inj ury may result
from improperly performed work.
(D Tips
-If you must replace the light bulbs your­
sel f, a lways remember that the engine
compartment of any vehicle is a hazard­
ous area to work in. A lways read and
heed all WARNINGS
<=> page 226, Engine
compartment<=> ,&..
- It is best to ask your authorized Audi
dealer whenever you need to change a
bulb.
