--=---=----------------
• in front-end collisions
• in rea r-end collisions
• in rollovers.
In some types of accidents the front a irbags, side c urtain airbags and
side airbags may be triggered together.
& WARNING
• Safety belts and the airbag system will onl y provide protection
when occupants are in the pro per seating position ~
page 22 6.
• If th e ai rb ag indicator light comes on when the vehicle is being
us ed, have the system ins pected immediately by your authorized
Audi dealer. The airbag ma y not work properl y when the vehicle
accelerat ion in a side collision is high enough to activate the
a irbag .•
How supplemental side airbags work
S ide airbags deploy instantly and can help reduce the risk
of upper torso injuries for occupants who are properly
restrained.
F ig . 2 19 Inflated side
a irb ag s o n left s ide o f
v e hicl e, re ar sid e
a irb ag
When t he system is triggered, the airbag is filled with p ropellant gas
and breaks through a seam in the seat s urface area marked "AIRBAG"
. It expands between the side trim panel and the passenger.
In order to he lp provide t his add it ion al protec tion, the side airbag
must inf late with in a fract io n of a second at very hig h speed and with
great force . The supp lemental side airbag cou ld injure you if your
seating position is not proper or upr ight or if items are located in the
area where the supplemental side airbag expands. This applies espe­
cially to children~
page 231, "Child Safe ty". Suppleme nta l side
airbags inflate between the occupant and the door panel on the side
of the vehicle that is s truck in certa in side collision~ fig. 219.
Although they are not a soft pillow, they can "cus hion" the impact
and in th is way t hey can hel p to reduce the risk of injury to the upper
part of the body .
A fine d ust may develop when the airbag dep loys. This is normal and
does not mean the re is a fire in the vehicle. •
Important safety instructions on the side
airbag system
Airbags are only supplemental res traints. Always prop­
erly wear safety belts and ride in a proper seating posi­
tion .
There is a lot that you and your passengers must know and act acco rd­
ing ly to he lp the safety be lts and a irbags do the ir job to prov ide
supplementa l protection .
& WARNING
An inflating side ai rbag can c au se se rious or fatal inju ry. Improp­
erly wearing safety belts and improper seating position s increase
the risk of serious personal injury and death whenever a veh icle is
being used.
• In order to redu ce the ri sk of injury when the supplemental
side airbag inflates:

Fuel supply and filling your fuel tank
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 fo r
winter or summer driving. During seasonal change-over, we suggest
that you fill up at busy gas stat ions where the seasonal adjustment is
more likely to be made in time.
0 Note
• Methano l fuels which do not meet these requirements may cause
corrosion and damage to plastic and rubber components in the fue l
system .
• Do not use fuels that fail to meet the specified criteria in this
chapter .
• If you are unab le to determine whether or not a particu lar fuel
blend meets the spec ifications, ask your serv ice 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 Aud i and are not covered under the New Vehicle or the Em is­
sion Control System Warranties.
• If you experience a loss of fuel economy or driveab ility and perfor­
mance 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 gaso line g rades contain
substances that can cause deposits to collect on v ital engine parts,
such as fuel injectors and intake valves. A lthough most gasoline
brands include additives to keep eng ine 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 officia l
webs ite (www.toptiergas.com).
After an extended period of using inadequate fuels, carbon deposit
build-ups can rob your engine of peak performance.
0 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 287.
You can find the fue l tank capacity of your vehicle in Technical Data
~page 360.
The label on the inside of the fuel filler flap tells you the correct fuel
for your ve hicle. For more information about fuel specifications, see
~page 283.
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 polluting the environment wh ile you refuel your veh icle . ..,_

Tires and wheels
Tires
General notes
Tires may be the least appreciated and most abused
parts of a motor vehicle.
T ir es may be the least apprec iated and most abused pa rts of a moto r
vehicle. Tires are, however, one of the most important parts of a
veh icle, parti cularly conside ring the comparative ly small patch of
rubber on eac h tire that assu res that all- important co ntact between
you , your ve hicle and the road .
Ma inta in ing t he correct t ire pressu re, making s ure that your veh icle
and i ts tires do not have to carry more weight than they can safely
hand le, avoid ing damage from road ha za rds and reg ula rly inspect ing
tires for damage incl ud ing c uts, s lashes irregular wea r and overall
condi tion are the mos t important th ings that you can do to help avoi d
sudden tire fa ilure includ ing t read separation and blowouts .
Avoiding damage
If you have to drive over a curb or sim ilar obstacle, drive very s lowly
and as close as poss ible at a right angle to the cu rb .
Always keep chemicals including grease, oil , gasoline and bra ke fl uid
o ff the t ires .
Inspect the ti res regularly for damage (cuts, crac ks o r bl ist ers, e tc .).
Remove any foreign bodies embed ded in the trea ds.
Storing tires
M ar k tires when yo u remove t hem to indica te the d irect ion of rota ­
tion . This ens ures yo u to be able to mo unt them co rrectly whe n you
re insta ll them.
Wh en r emoved, t he wheels or tires s hould be sto red in a c ool, dry and
preferably da rk p lace. Sto
re tires in a ver tica l pos it ion if they a re not mounted on rims, in a
hor izonta l position if they are mo unted on r ims.
New tires
N ew tires have to be bro ken in~ & .
Th e tread dep th of new tires may v ary, ac cor ding to t he type an d
make of t ire and the tread pattern.
Hidden damage
Dama ge to t ires and rims is often not readi ly visible . If yo u notice
unusu al v ib rat ion o r the veh icle pulls to one sid e, t his may i ndicate
that one of the tires has been damaged. The tires must be c hecke d
i m medi ately by an a uthor ized A udi deale r or quali fied w or ksh op .
Unidirectional tires
A u nidirectional tire can be identified by arrows on the sidewall, that
point in the d irect io n the tire is des igned to rotate. Yo u m ust follow
t he s peci fied dire ction of ro tation . T his is nece ssary so th at t hese
tires can develop the ir optimum c haracter istics regarding gr ip, road
noise, we ar and hy dropl aning res istance. For more informa tion
~page 341 .
& WARNING
New tires or tires that are old , worn or damaged cannot provide
maximum control and braking ability.
• New tires tend to be slippery and must be broken in. To reduce
the risk of losing control, a collision and serious personal injuries, drive with special care for the first 350 miles (560 km) .
• Driving with worn or damaged tires can lead to loss of control,
sudden tire failure , including a blowout and sudden deflation ,
crashes and serious personal injuries. Have worn or damaged tires
replaced immediately. .,_

Inco rrect wheel al ignment
Incorrect wheel alignment can cause excessive tire wear, impairing
the safety of the vehicle . If tires show excessive wear, have the wheel
alignment checked by an authorized Audi dealer or qualified wo rk­
shop .
All Wheel Drive
Vehicles with quattro ® must always have tires of the same s ize,
constr uction and tread type . For details see~
page 257.
& WARNING
Sudden tire failure c an lead to loss of control , a cra sh and seriou s
personal injur y!
• Never drive a vehicle when the tread on any tire i s worn down
to the wear ind icators .
• Worn tire s are a s afety hazard, they do not grip w ell on wet
roads and increa se your risk of "h ydroplaning" and lo ss of control.
• Always keep chemical s that can cause tir e damage, su ch as
grea se , oil , gasoline and brake flu id away from tires .
• Tires age even if they ar e not b eing used and can fail suddenly ,
especially at high speeds. Tires that are more than 6 year s old can
only be used in an emergency and then with special care and at
lower speeds .
• Never mount u sed tir es on your vehicle if you are not sure of
their "previous history. " Old used tires m ay have been damaged
even though the damage cannot be seen that can lead to sudden
tire failure and loss of vehicle control. •
New tires and replacing tires and wheels
New tires and wheels have to be broken in.
