technical specifications AUDI S8 2010 Owners Manual

Fuel supply and filling your fuel tank
Blend of gasoline and MTBE
• Anti-knock index must be 87 AKI or higher.
• Blend must contain not more than 15% MTBE.
Seasonally adjusted gasoline
Many gasoline grades are blended to perform especially well fo r
winter or summer driving. During seasonal change-over, we suggest
that you fill up at busy gas stat ions where the seasonal adjustment is
more likely to be made in time.
0 Note
• Methano l fuels which do not meet these requirements may cause
corrosion and damage to plastic and rubber components in the fue l
system .
• Do not use fuels that fail to meet the specified criteria in this
chapter .
• If you are unab le to determine whether or not a particu lar fuel
blend meets the spec ifications, ask your serv ice station or its fuel
supplier.
• Do not use fuel for which the contents cannot be identified.
• Fuel system damage and performance problems resulting from
the use of fuels different from those specified are not the responsi­
bility of Aud i and are not covered under the New Vehicle or the Em is­
sion Control System Warranties.
• If you experience a loss of fuel economy or driveab ility and perfor­
mance problems due to the use of one of these fuel blends, we
recommend that you switch to unblended fuel.•
Gasoline additives
A major concern among many auto manufacturers is carbon deposit
build-up caused by the type of gasoline you use. Although gasoline grades differ from one manufacturer to another,
they have certain things
in common. All gaso line g rades contain
substances that can cause deposits to collect on v ital engine parts,
such as fuel injectors and intake valves. A lthough most gasoline
brands include additives to keep eng ine and fuel systems clean, they
are not equally effective.
Audi recommends using TOP TIER Detergent Gasoline. For more
information on TOP TIER Detergent Gasoline, please go to the officia l
webs ite (www.toptiergas.com).
After an extended period of using inadequate fuels, carbon deposit
build-ups can rob your engine of peak performance.
0 Note
Damage or malfunction due to poor fuel quality is not covered by the
Audi New Vehicle Limited Warranty. •
Fuel tank
Fuel filler neck
The fuel filler neck is located on the right rear side panel behind the
fuel filler flap .
If the power locking system should fail, you can still open the flap
manually -for detailed instructions see~
page 287.
You can find the fue l tank capacity of your vehicle in Technical Data
~page 360.
The label on the inside of the fuel filler flap tells you the correct fuel
for your ve hicle. For more information about fuel specifications, see
~page 283.
Your vehicle fuel tank has an on board refuel ling vapor recovery
system. This feature helps to prevent fuel vapors from escaping from
the tank and polluting the environment wh ile you refuel your veh icle . ..,_

Audi Original tire
Sever snow conditions
Tire ply composition and materials used
Treadwear, traction and temperature grades Ma ximum perm issible inflation pressure
The tires and rims are essential parts of the vehicle's design . The tires
and rims approved by Audi are specially matched to the characteris­
tics of the vehicle and can make a major contribution to good road
holding and safe handling when in good condition and properly
inflated =>
&.
We recommend that all work on tires and wheels be performed by an
authorized Audi dealer. They are familiar with recommended proce­
dures and have the necessary special tools and spare parts as well as
the proper facilities for disposing of the old tires.
Authorized Audi dealers have the necessary information about tech­
nical requirements for installing or changing tires and rims.
Replacing tires and wheels
Tires should be replaced at least in pairs and not individually (for
example both front tires or both rear tires together).
Be sure to read and heed the information to the tire pressure moni­
toring system* =>
page 320.
Always buy replacement radial tires that have the same specifications
as the tires approved for your vehicle by Audi. Replacement tires must
always have the same load rating specification as the original equip­
ment or approved optional tires listed in the table=>
page 310.
Audi-approved specification tires are specially matched to your
vehicle and its load limits, and can contribute to the important road-
Safety first
holding, driving characteristics, and safety of the vehicle. The table
(=>
page 310) lists specifications of the tires approved for the Audi
models covered by your Owner's Literature.
The tire pressure label located either on driver's side B-pillar or inside
the fuel filler flap (=>
page 310, fig. 253) lists the specifications of
the original equipment tires installed on your vehicle at the time it
was manufactured.
Federal law requires tire manufacturers to place standardized infor­
mation on the sidewall of all tires=>
page 318, fig. 256. This infor­
mation identifies and describes the fundamental characteristics, the
quality grade of the tire and also provides a tire identification number
for safety standard certification and in case of a recall.
Tire specifications
Knowledge of tire specifications makes it easier to choose the correct
tires. Radial tires have the tire specifications marked on the sidewall,
for example:
255/45 R 18 99 H
This contains the following information:
P Indicates the tire is for passenger cars (where applicable)
255 Nominal tire width in mm of the tire from sidewall edge to side-
wall edge. In general, the larger the number, the wider the tire
45 Height/width ratio in percent (aspect ratio)
R Tire construction: Radial
18 Rim diameter code (in inches)
99 Load rating code
H Speed rating letter code
XL (or "xl", "EXTRA LOAD" or "RF") indicates that the tire is a "Rein­
forced" or an "Extra Load" tire
M+S (or "M/5") Indicates that the tire has some mud and snow capa­
bility
The tires could also have the information of direction of rotation
=>

uted evenly i n the vehicle (passengers and lug gage). When trans ­
porting a heavy load i n the luggage compartment, ca rry the load as
near to the rear axle as possible so that the ve hicle's handling is not
impa ired.
• Do not exceed the max imum permissible axle loads o r the
maximum gross veh icle weight. Always remember that the vehicle's
handling will be affecte d by the extra load. Therefore, adjust your
speed according ly .
