Many gasoline grades are blended to perform
especia lly we ll for winter or summer driving.
During seasonal change-over , we suggest that
you fill up at busy gas stations where the sea sonal adjustment is more likely to be made in
time.
Q;) 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 fuels that fail to meet the
spec ified criter ia in this chapter .
- If you are unable to determine whether
or not a particular fuel blend meets the
spec ificat ions, ask your service station or
i ts 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 respons ibility of Audi and are not
covered under the New Vehicle or the
Emission Control System Warranties.
- If you experience a loss of fue l 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 cer tain
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 effec
tive.
Fuel supply and filling your fuel tank 191
Audi recommends using TOP TIER Detergent
Gasoline . For more information on TOP TIER
Detergent Gasoline, please go to the official
website (www .toptiergas .com) .
After an extended period of using inadequate
fuels, built -up carbon deposits can rob your
engine of peak performance.
CJ) Note
Damage or malfunction due to poor fuel
quality is not covered by the Audi New Ve
hicle Limited Warranty.
Fuel tank
Fuel filler neck
The fuel filler neck is located on the right rear
s ide 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 193.
You can find the fuel tank capacity of your ve
hicle in
~page 262 .
The label on the inside of the fuel filler flap
tells you the correct fuel for your vehicle. For
more information about fuel specifications,
see
~ page 190 .
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 pollut ing the environment while you
refuel your vehicle. In order to fill the tank
properly while protecting the environment,
please follow this refueling procedure careful
ly.
A WARNING ~
Under normal operating conditions, never
carry additional fuel containers in your car.
Gas canisters and other containers used to
transport fuel can be dangerous. Such con
tainers, full or empty, may leak and could
cause a fire in a collision . If you must
transport fuel to use for your lawn mower, ..,.

Tires
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, particularly
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
regularly 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 failure 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, oil, gasoline and
brake fluid off the tires.
Inspect the tires regularly for
damage (cuts, cracks 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 mounted on
rims, in a horizontal position if
they are mounted on rims.
New tires

wear on steering, suspension and tires. A wheel must also be
rebalanced when a new tire is
installed.
Incorrect wheel alignment
Incorrect wheel alignment can
cause excessive tire wear, im
pairing the safety of the vehi
cle. If tires show excessive
wear, have the wheel alignment checked by an authorized Audi
dealer or qualified workshop.
All wheel drive
Vehicles with quattro must al
ways have tires of the same
size, construction and tread
type. For details see
¢page 176.
A WARNING
Sudden tire failure can lead
to loss of control, a crash and serious personal injury!
-Never drive a vehicle when the tread on any tire is worn down to the wear indica
tors.
-Worn tires are a safety haz
ard, they do not grip well on
wet roads and increase your risk of "hydroplaning" and
loss of control.
Tires and wheels 229
-Always keep chemicals that can cause tire damage, such
as grease, oil, gasoline and
brake fluid away from tires.
-Tires age even if they are not being used and can fail
suddenly, especially at high speeds. Tires that are more
than 6 years old can only be used in an emergency and
then with special care and
at lower speeds.
-Never mount used tires on your vehicle if you are not sure of their "previous histo
ry." Old used tires may have
been damaged even though
the damage cannot be seen
that can lead to sudden tire
failure and loss of vehicle
control.
