airbags will deploy only once and on ly in certain kinds of accidents
- you r sa fety belts are always there to offer protection.
Vehicle damage , repair costs or even the lack of vehic le damage are
not necessarily an indication of over -sensitive or failed airbag acti ­
vation. In some col lisions , both front and side airbags may inflat e.
Remember too, that airbags will deploy only once and only in
certain ki nds of col lis ions -your sa fety belts are always there to
o ff er prot ection in those acc idents in which airbags are no t
s u pposed to deploy or when they have already dep loyed.
The side airbag system will not deploy:
• when the ign it ion is turned off
• in side collisions when the acceleration measured by the senso r
is too low
• in fron t-end col lisio ns
• in rear- end co llisions
• in rollovers.
In some types of accidents the front airbags, side curtain airbags
and s ide ai rbag s may be trigge red together.
& WARNING
• Safety belts and the airbag system will only provide protection
when occupants are in the proper seating position=>
page 163.
• If the airbag indicator light comes on when the vehicle is being
used , have the system inspected immediately by your author ized
Audi dealer . The airbag may not work properly when the vehicle
a cceleration in a side collis ion is high enough to activate the
airbag .•
How supp lemental side airbags work

ment
When the system is triggered, the airbag is fi lled with propellant gas
a n d br eaks thr oug h a seam in th e se at sur face area marke d
"AIRBAG". It expands between the side t rim panel and the
p assenger . In or der to he lp provide this ad ditional p rotection, t he
side airbag must inflate w ithin a fraction of a second at very high
speed and wi th great forc e. The supp lemental side air bag could
in jure you if your seating position is not pro per or upright or if items
are locate d in the a rea where the suppleme ntal s ide airbag e xpands.

collision => fig . 144.
Altho ugh they are not a so ft p illow , th ey can "cushion" the impact
and in this way they can he lp to reduce the risk of injury to the upper
p ar t of the bod y.
A fine dust may develop when the ai rbag deploys. This is normal
and does not mean there is a fi re in the vehicle. •

Fuel supply and filling your fu el tank
Blend of g asoline and ethanol (grain al cohol or ethyl alcoho l}
• Anti -knock index must be 87 A KI or higher.
• Blend must not contain more than 10% ethanol.
Blend of gasoline and MTBE
• Anti -knock index mus t be 87 AKI or higher.
• Blend must contain not more than 15% MTBE.
Seasonally adjusted ga sol ine
Many gaso line grades are blended to perform especia lly wel l for
winter or summer d rivi ng. During seasona l 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 fue ls 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 specif ied criteria in this
chapter .
• If you are unable to determine whether or not a particu lar fuel
blend meets the specifications, ask your service station or its fuel
supplier.
• Do n ot use fuel for w hich the con tents cann ot be iden tified.
• Fuel system damage and performance p rob lems resulting from
th e use of fuels d ifferen t from those speci fied a re not the resp onsi ­
bility of Audi and are not covered under the New Vehicle or the
E mi ssion Contr ol System Warran tie s.
• If you experience a loss of fue l economy or driveabi lity and
performance p ro blems due to t he use of o ne of these fuel blends,
we recommend that you switch to unblended fuel. •
Gasoline additives
A major concern among many auto manufacturers is carbon
d epos it build -up caused by the type of gasol ine y ou use.
A lthough gasoline grades differ from one manufacturer to another,
t hey have certain things in common . A ll gas oline g rades co ntain
substances that can cause deposits to collect on vital engine parts,
such as fue l injectors and intake valves. A lthough most gaso line
brands include additives to keep eng ine and fue l systems clean,
they are not equal ly effective .
Audi reco mmends using TOP TIER De tergent Gasol ine. F or mo re

A ft er an extended period of usin g inadequate fuels, bui lt -up carbon

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

Incorrect wheel alignment
Incorrect wheel alignment can cause excess ive tire wea r, im pairing
the safety of the vehic le. If tires show excessive wear, have the
whee l alignment c hecked by an au th o rize d Audi deale r or qualifie d
wo rkshop.
All Wheel Drive
Vehicles with quattro® must always have tires of the same size, c ons truc tion and tread type. F or details see ~ page
19 4.
& WARNING
Sudden tire failure can lead to los s of control, a crash and serious
personal injury !
• Never drive a vehicle when the tread on any tire is worn down
to the wear indicators .
• Worn tires are a safety hazard, they do not grip well on wet
roads and increase your risk of "hydroplaning " and loss of control .
• Always keep chemicals that can cause tire dam age , such as
grease, oil , gasoline and brake fluid aw ay 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 history." Old used tires may have been damaged
even though the damage cannot be seen that can lead to sudden
tire failure and los s of veh icle control. •
