Seasonally adjusted gasoline
Many gasoline grades are blended to perform
espec ially we ll for winter or summer driving.
During seasonal change-over, we suggest that
you fill up at busy gas stat ions where the sea­
sonal adjustment is more likely to be made in
time .
(D Note
-Methanol fuels which do not meet these
requirements may cause corrosion and
damage to plastic and rubber compo­
nents in the fuel system .
- Do not use fue ls that fail to meet the
specified criter ia in this chapter.
- If you are unable to determine whether
or not a particular fue l blend meets the
specifications, ask your service station or
its fuel supp lier.
- 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 responsibility 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 prob­ l ems 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 manufac­
turers 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 supply and filling your fuel tank 207
fuel systems clean, they are not equally effec ­
tive .
A udi recommends using TOP TIER Detergent
Gasoline. For more info rmation on TOP TIER
Detergent Gasoline, please go to the official
website (www.toptiergas.com).
After an extended period of using inadeq uate
fuels, carbon deposit build-ups can rob your
engine of peak performance.
Q) Note
Damage or malf unct ion due to poor fue l
quality is not covered by the Aud i New Ve­
hicle Limited Warranty.
Fuel tank

hicle in

more information about fuel specifications,
see
¢ page 206.
Your vehicle fue l tank has an on board refuel­
li ng vapor recovery system. This feature helps
to prevent fuel vapors from escaping from the
tank and polluting the environment while you refuel your vehicle . In order to fill the tank
properly while protecting the environment,
please fo llow this refueling procedure careful­
ly.

General notes
Tires may be the least appreci ­
ated and most abused parts of
a motor vehicle.
Ti res may be the least appreci ­
ated and most abused parts of
a motor vehicle. Tires are, how­
ever, one of the most important
parts of a vehicle, partic ularly
considering the comparatively
small patch of r ubber on each
tire that assures that all-impor­
tant contact between you, your
vehicle and the road.
Maintaining the co rrect tire
p ressure, making sure that your
vehicle and its tires do not have
to carry more we ight than they
can safe ly handle, avoiding
damage from road hazards and
regular ly inspecting tires for
damage including cuts, s lashes
irregular wear and overall con ­
d ition are the most important
things that you can do to help avoid sudden tire fai lure inc lud ­
ing tread separation and blow­
outs.
Avoiding damage
If you have to drive over a curb
or similar obstacle, drive very
slowly and as close as possible
at a right angle to the curb.
Always keep chemicals includ­
ing grease, o il, gasoline and
brake fluid off the tires.
Inspect the tires regularly for
damage (cuts, c racks or blis­
ters, etc.). Remove any foreign
bodies embedded in the treads.
Storing tires
Mark tires when you remove
them to indicate the direction
of rotation . This ensures you to
be able to mount them correct ­
ly when you reinstall them .
When removed , the wheels or
tires should be stored in a cool,
dry and preferably dark p lace.
Store tires in a vertical position if they are not mounte d on
r ims, in a horizontal position if
they are mounted on rims.
New tires
New tires have to be broken in

may vary , according to the type .,.
