-If you are unable to determine whether or
not a particular fuel blend meets the speci­
fications, ask your service station or its fuel
supplier.
- Do not use fuel for which the contents can­
not be identified.
- Fuel system damage and performance prob­
lems resulting from the use of fuels differ­
ent from those specified are not the respon­
sibility 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 manufactur­
ers is carbon deposit build-up caused by the type
of gasoline you use.
Although gasoline grades differ from one manu ­
facturer 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.
Al­
though most gasoline brands include additives to
keep engine and fuel systems clean, they are not
equally effective .
Audi recommends using TOP TIER Detergent Gas­
oline. For more information on TOP TIER Deter­
gent Gasoline, please go to the official website
(www.toptiergas .com) .
After an extended period of using inadequate
fuels, carbon deposit build-ups can rob your
en­
gine of peak performance.

Checking and Filling
~ After the fuel pump has switched off, wait five seconds before removing it to allow the rest of
the fuel to finish dripping into the fuel tank.
~ Turn the fue l cap clockwise until you hear it
lock.
~ Close the fuel filler door and then press on the
left side until it latches .
The correct fuel type for your vehicle can be
found on a label located on the inside of the fuel
filler door. For additional information on fuel,
see
Qpage 314 .
For the tank capacity in your vehicle, refer to the
Technical Data
Qpage 382.
To reduce the risk of fuel leaking out or vapors
escaping, make sure that the fuel tank is closed
correctly. Otherwise
thP ¢..iff indicator light will
turn on.
If the centra l locking system malfunctions, the
fuel filler door may emergency release
Qpage317.
A WARNING
An improper fueling procedure and improper
handling of fuel can lead to explosions, fires,
severe burns and other injuries.
-Do not smoke and keep away from open
flames.
-The ignition must be switched off when re­
fueling.
-Cell phones, radio devices and other radio
equipment should always be switched off
when refueling. Electromagnetic rays could cause sparks and start a fire.
-If you do not insert the fuel pump nozzle all
the way into the filler tube, then fuel can
leak out. Spilled fuel can ignite and start a
fire.
-Never get into the vehicle when refueling. If
there is an exceptional situation where the
vehicle must be entered, close the door and
touch a metal surface before touching the
fuel pump nozzle again. This will reduce the
risk of electrostatic discharge that can cause
flying sparks. Sparks can start a fire when
refueling.
316
A WARNING
We recommend that you do not transport any
fuel containers in the vehicle. Fuel could leak
out of the container and ignite, especially dur­
ing an accident. This can cause explosions,
fires and injuries.
-If you must transport fuel in a fuel contain­
er, please note the following:
-Always place a fuel container on the
ground before filling. Never fill the fuel
container with fuel while it is in or on the
vehicle. Electrostatic charge can occur
while refueling and the fuel vapors could
ignite .
-For fuel containers made of metal, the
fuel pump nozzle must always maintain
contact with the container to reduce the
risk of static charge.
-Insert the fuel pump nozzle as far as pos­
sible into the filler opening while refuel­
ing.
-Follow legal requirements when using,
storing and transporting fuel containers.
-Make sure that the fuel container meets
the industry standards, for example ANSI
or ASTM F852-86.
@ Note
-Remove fuel that has overflowed onto any
vehicle components immediately to reduce
the risk of damage to the vehicle.
-Never drive until the fuel tank is completely
empty. The irregular supply of fuel that re­
sults from that can cause engine misfires.
Uncombusted fuel will enter the exhaust
system and increase the risk of damage to
the catalytic converter.
@I For the sake of the environment
Do not overfill the fuel tank, otherwise fuel
can leak out when the vehicle is warming up.
© Tips
The fuel filler door on your vehicle does not lock if you lock the vehicle from the inside us-

Wheels
Wheel bolts and rims
Wheel bolts
Wheel bolts must be clean and loosen/tighten
easi ly.
Rims
Rims with a bolted rim ring* or with bolted wheel
covers* consist of multiple pieces . These compo­
nents were bolted together using special bolts
and a special procedure . You must not repair or
d isassemble
them ¢_&. .
_& WARNING
Wheel bolts that are tig htened or repaired in­
correctly can become loose and result in loss
of vehicle control, which increases the risk of
an accident. For the correct tightening specifi­
cation, see
q page 364, After changing a
wheel.
- Always keep the wheel bolts and the
threads in the wheel hub clean and free of
grease.
- Only use wheel bolts that fit the rim.
- Always have damaged rims repaired by an
authorized Audi dealer or authorized Audi
Service Facility. Never repair or disassemble
rims yourself, because this increases the risk
of an accident.
Winter tires
Winter tires significantly improve the vehicle 's
handling when driving in winter conditions . Be­
cause of their construction (width, compound,
tread pattern), summer tires provide less trac­
tion on ice and snow.
.,. Use winter tires on all four wheels .
.,. Only use winter tires that are approved for your
vehicle.
.,. Please note that the maximum permitted
speed may be lower with winter tires
¢ A in
General information on page 330.
An author­
ized Audi dealer or authorized Audi Service Fa­
cility can inform you about the maximum per­
mitted speed for your tires .
.. Check the tire pressure after installing wheels
¢page 341 .
346
The effectiveness of winter tires is reduced great­
ly when the tread is worn down to a depth of
0.157 inch (4 mm). The characteristics of winter
tires also decrease greatly as the tire ages, re­
gardless of the remaining tread.
@) For the sake of the environment
Reinstall summer tires at the appropriate
time, because they provide better handling
when roads are free of snow and ice. Summer
tires cause less road noise, tire wear and fuel
consumption .
(D Tips
You can also use all season tires instead of
winter tires. Please note that in some coun­
tries where winter tires are required, only
winter tires with the
& symbol may be per­
mitted.
Snow chains
Snow cha ins not only improve the driving in win­
ter road conditions, but also the braking.
.,. Only install snow chains on the front wheels.
This applies also to vehicles with all wheel
drive*.
.. Check and correct the seating of the snow
chains after driving a few feet, if necessary. Fol­
low the instructions from the manufacturer .
.. Note the maximum speed of 30 mph (SO km/
h). Note the local regulations.
Use of snow chains is only permitted with certain
rim/tire combinations due to technical reasons.
Check with an authori zed Audi dealer or author­
ized Audi Service Facility to see if you may use
snow chains .
Use
fine-mesh snow chains. They must not add
more than 0.53 inch (13.5 mm) in height, includ­
ing the chain lock .
You must remove the snow chains on roads with­
out snow . Otherwise, you cou ld impair driving
ability and damage the tires .
