How supplemental side airbags work
Side air bags deploy inst ant ly a nd con help reduce the risk
of u pper torso injuries for oc cupants wh o ore p roperly
restrained.

Safety first
Airbag system
"AIR BAG". It expands between the side trim pane l and the
passe nger. In o rder to hel p provide this a dditional protecti on, the
s ide a irbag must inflate w ithin a fraction of a second at very high
speed a nd w ith grea t force. T he suppleme ntal side ai rbag could
injure you if your seating position is not proper or upright or if items
are located in the a rea where the s upp lemental si de air bag expands .

I I irechnical 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, built-up carbon
deposits 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 unlocking system should fail, you can still open the flap manu ­
ally -for detailed instructions see=>

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, particu larly considering the comparatively small patch
of rubber on each tire that assures that all -important contact
between you, your vehic le 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 regularly inspecting tires for damage inc luding cuts, s lashes 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
blowouts.
A vo iding d am age
If you have to drive over a curb or similar obstac le, drive very slowly
and as close as possible at a right angle to the curb.
A lways keep chemica ls including grease, oi l, gaso line and brake
fluid off the tires.
Inspect the ti res regu larly for damage (cuts, cracks or b listers, etc.l .
Remove any foreign bodies embedded in the treads.
Storing tir es
Mark tires when you remove them to indicate the direction of rota ­
t ion. This ensures you to be able 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.
S tore tires in a vertical pos it ion if they a re not mounted on r ims, in
a horizonta l position if they are mounted on rims.
New tir es
New tires have to be broken in=>&.
The tread depth of new ti res may vary, according to the type and
make of tire and the tread pattern.
H idd en damage
Damage to tires and rims is often not readily visible. If you notice
unusual vibration or the vehicle pu lls to one s ide, this may indicate
that one of the tires has been damaged . The tires must be checked
immediately by an authorized Audi dealer or qualified workshop .
Unidire cti ona l t ires
A unidirectional tire can be identif ied by arrows on the sidewa ll, that
point in the direction the tire is designed to rotate . You must fo llow
t he specified directio n of rotation . This is necessary s o that these
tires can develop their optimum characteristics regarding grip, road noise, wear and hydrop laning resistance . For more information
