2009 AUDI S6 technical specifications

Operating instructions
Max im um tra iler weight
A trailer for your vehicle is limited to a typical class 1 or class 2
trailer.
T ra ile r l oa d di stributio n
Be sure the load in the trailer is he ld securely in place to prevent it
from shifting forward, backward or sideways .
Never allo w a passe nger to r ide in a tr aile r~ & in "Driving instruc­
tions" .
Engin e c oolin g sys te m
Towing a trailer makes the eng ine work harder. It is important that
the cooling system's performance is up to the additiona l load. Make
sure that the coo ling system has enough fluid .
Tire pr ess ure
When towing a trailer, inflate the tires of your vehicle to the co ld tire
pressure listed under "Full load" on the labe l located on the driver's
side B -pillar {visible when the door is open). Inflate trailer tires to
trailer and tire manufacturers' specifications .
Light s
The head light settings should be checked with the trailer attached
before driving off . Check to make sure both vehicle and trai ler lights
are working properly.
Safe ty chains
Be sure trailer safety chains are properly connected from the trailer
to the hitch on the vehicle. Leave e nough slack in the chains to
permit turning corners. When you insta ll safety chains, make sure
they will not drag on the r oad when you a re driving .
The chains should cross under the tra iler tongue to prevent it from
dropping in case of separation from the hitch.

Driving instructions
Driving with a trailer always requires extra care and
consideration.
To obtain the best possible handling of veh icle and trailer,
please note t he following :
- Do not tow a loaded trailer when your car itself is not
loaded.
Be espec ia lly careful whe n passing other vehicles.
- Observe s peed l imits .
Do not drive at the maximum permiss ible speed .
Always apply brakes ear ly.
Moni tor t he temperature ga uge.
Weight distr ibution
Towing a loaded trailer with an empty car results in a highly
unstable distr ibution of weight. If this cannot be avoided, drive at
very low speeds only to avoid the risk of losing steering control.
A "balanced" rig is easier to operate and control. This means that
the tow vehicle should be loaded to the extent possible and perm is ­
s ib le, while keeping the trailer as light as possib le under the circum ­
stances . Whenever possible, transfe r some cargo to t he luggage
compartment of the tow vehicle whi le observing tongue load
requirements and vehicle loading considera tions . .,
Vehicle care Do-it-yourself service Technical data

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. •
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 299.
You can find the fuel tank capacity of your vehicle in Technical Data
=> page 369. .,_

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

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.
