2009 AUDI S6 gas type

Fuel supply and filling your fuel tank
Blend of gasoline and ethanol (grain alcohol or ethyl alcohol}
• Anti-knock index must be 87 AKI or higher.
• Blend must not contain more than 10% ethanol.
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 for
winter or summer driving. During seasonal change -over, we suggest
that you fill up at busy gas stations where the seasonal adjustment
is more likely to be made in time.
0 Note
• Methanol fuels which do not meet these requirements may
cause corrosion and damage to plastic and rubber components in
the fuel system.
• Do not use fuels that fail to meet the specified criteria in this
chapter.
• If you are unable to determine whether or not a particular fuel
blend meets the specifications, ask your service 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 Audi and are not covered under the New Vehicle or the
Emission Control System Warranties.
• If you experience a loss of fuel economy or driveability and
performance 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 gasoline grades contain
substances that can cause deposits to collect on vital engine parts,
such as fuel injectors and intake valves. Although most gasoline
brands include additives to keep engine 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 offi­
cial website (www.toptiergas.com).
After an extended period of using inadequate fuels, carbon deposit
build-ups can rob your engine of peak performance.
(D Note
Damage or malfunction due to poor fuel quality is not covered by
the Audi New Vehicle Limited Warranty. •

A discharged battery can freeze at temperatures of only O °C. A llow
a frozen battery to thaw completely before attempting to charge it
~ & .However, we recommend not using a thawed battery again
because the battery casing can be cracked due to ice formation and
can leak battery acid.
Batt ery c harg ing (Ma ximum ch arging rate of 30
a mps /14 .8 Volt )
When charging at /ow voltages (e.g. with a trickle charg er), the
ba ttery cables do not have to be disconnected first. The battery caps
should
not be opened when charging a battery.
I t is not necessary to remove the battery from the luggage compart­
ment .
Fa st cha rging the batt ery (chargi ng ra te ab ove 14 .8
Volt s)
For technical reasons do not use a battery charger that uses vo ltage
greater than 14.8 Volts to charge your vehic le's battery.
& WARNING
C harging a battery can be d angerou s.
• Alwa ys follo w the oper ating instruct ions pro vided b y the
battery charger manuf acturer when charging your b attery .
• Neve r charge a frozen battery. It m ay explode be cau se of gas
tr apped in the i ce. Allow a frozen battery to thaw out fir st.
• Do not reuse batteries wh ich were fro zen. The battery housing
m ay hav e crac ked and wea kened when the b atte ry fro ze .
• Charge the battery in a well ventilated area. Keep away from
open fla me or ele ctri cal s par k. Do not smok e. Hydrogen ga s gener ­
ated by the battery is explo sive.
&_ W ARN ING (c ontinued )
• To redu ce the danger of explo sion, never connect or d isconnect
c h ar ger cable s while the charger is ope rat ing .
• Batte ry acid that may spill durin g charging should be w ashed
off with a sol ution of warm water and b aking soda to neutralize
the acid .
0 Note
Never use a fast charger as a booster to start the engine . This wi ll
seriously damage sensitive electronic components, such as control
units, re lays, radio, etc ., as well as the battery charger. •
Battery replacement
The new battery must have the same specifications and
dimensions as the original equipment battery.
Intelligent energy management in your vehicle is responsib le for
distributing the e lectrica l energy throughout your vehicle
~ page 269 . The intelligent energy management system will keep
the engine battery charged better then vehicles without this system.
To make sure the additional electrical energy is availab le once again
after you have changed the battery, we recommend that you insta ll
batteries of the same type and manufacture only (the same as those
insta lled at the t ime your vehicle was de livered). Specif ications are
listed on the battery housing . Your authorized Audi dealer wi ll then
code the battery management con trol unit.
I f it is not possib le to use a battery of this type, the new battery must
have the same capacity, voltage (12 volts), amperage, construction
and p lug sealing .
When installing the battery, make sure the ignition and all electrical consumers are tur ned off.

Tires and wheels
Tires
General notes
Tires may be the least appreciated and most abused parts
of a motor vehicle.
Tires may be the least appreciated and most abused parts of a
motor vehicle. Tires are, however, one of the most important parts
of a vehicle, particularly considering the comparative ly sma ll patch
of rubber on each tire that assures that all- important contact
between you, your vehicle and the road .
Maintaining the correct tire pressure, making sure that your vehicle
and its tires do not have to carry more weight than they can safely
handle, avoiding damage from road hazards and regu lar ly
inspecting tires for damage inc luding cuts , slashes irregular wear
and overa ll condition are the most important things that you can do
to help avoid sudden tire failure including tread separation and
b lowouts .
Avoiding dama ge
If you have to drive over a curb or similar obstacle, drive very slow ly
and as close as possible at a right angle to the curb.
A lways keep chemica ls includ ing grease, oil, gasoline and brake
f luid off the tires.
I nspec t the tires regularly for damage (cuts, cracks or blis ters, etc.l.
Remove any foreign bodies embedded in the treads.
Storing tires
Mark tires when you remove them to indicate the direction of rota ­
tion . This ensu res you to be ab le to mount them correctly when you
reinstal l them. When removed, the wheels or tires shou
ld be stored in a coo l, dry
and preferably dark place.
St ore t ires in a vertical posit ion if they a re not mounted on rims, in
a horizontal position if they are mounted on rims.
New tire s
New tires have to be broken in~&.
The tread dep th of new tires may va ry, according to the type and
make of tire and the tread pattern.
Hidden d ama ge
Damage to tires and rims is often not readily visible. If you notice
unusua l vibration or the vehicle pul ls to one side, this may indicate
that one of the tires has been damaged . The tires must be checked
immed iately by an authorized Audi dealer or qualified workshop .
Unidire ction al tir es
A unidirectio nal tire can be iden tif ied by arrows on the s idewa ll, that
point in the direction the tire is designed to rotate. You must follow
the specified direction of ro tation . This is necessary so that these
tires can deve lop their optimum characteristics regarding grip, road
noise, wear and hydroplaning resistance . For more information
~ page 349.
in. WARNING
Ne w tire s or tire s that are old , worn or damaged cann ot pro vide
m aximum cont rol and braking ability.
• New tire s tend to be slippe ry and m ust be broken in . To redu ce
the risk of losing control, a colli sion and seriou s per sonal injurie s,
drive with speci al care for t he fi rst 350 m ile s ( 560 km l.
• Driving with worn or damaged t ire s can lead to lo ss of co ntrol ,
