168 Airbag system
Always remember that the side airbag system
can only help to protect you if you are wearing
your safety belt and wearing it properly. This
is another reason w hy you should always wear
your safety belts, not just because the law re­
quires you to do so
Q page 138, General
notes.
It is important to remember that while the
supplemental side airbag system is designed
to reduce the likelihood of serious injuries,
other injuries, for example, swelling, bruising,
friction burns and minor abrasions can also be
associated with deployed side airbags. Re­member too, side airbags will deploy only
once and only in certain kinds of accidents -
your safety belts are always there to offer pro­
tection .
Vehicle damage, repair costs or even the lack
of vehicle damage are not necessarily an indi­
cation of over-sensitive or failed airbag activa­
tion. In some collisions, both front and side
airbags may inflate. Remember too, that air­
bags will deploy only once and only in certain
kinds of collisions -your safety belts are al­
ways there to offer protection in those acci ­
dents in which airbags are not supposed to
deploy or when they have already deployed.
The side airbag system will not deploy:
- when the ign ition is switched off
- in side collisions when the acceleration
measured by the sensor is too low
- in front-end collisions
- in rear-end collisions
- in rollovers.
In some types of accidents the front airbags,
side curtain airbags and side airbags may be
triggered together.
.&_ WARNING
- Safety belts and the airbag system will
only provide protection when occupants
are in the proper seating position
Qpoge 169.
- If the airbag indicator light Q page 19
comes when the vehicle is being used,
-
have the system inspected immediately
by your authorized Audi dealer. It is pos­
sible that the airbag will inflate when it
is not supposed to, or will not inflate
when it should.
How supplemental side airbags work
Side airbags deploy instantly and can help re­
duce the risk of upper torso injuries for occu­
pants who are properly restrained .
Fig. 164 Inflated side airbags on left s ide of vehicle ,
rear side a irbag
When the system is triggered, the airbag is
filled with propellant gas and breaks through
a seam in the seat surface area marked "AIR­
BAG".
It expands between the side trim panel
and the passenger. In order to help provide
this additional protection, the side airbag must inflate within a fraction of a second at
very high speed and with great force. The sup­
plemental side airbag could injure you if your
seating position is not proper or upright or if
items are located in the area where the sup­
plemental side airbag expands. This applies
especially to children
Q page 173, Child Safe­
ty .
Supplemental side airbags inflate be­
tween the occupant and the door panel on the side of the vehicle that is struck in certain side
collision
Q fig. 164 .
Although they are not a soft pillow, they can "cushion" the impact and in this way they can
help to reduce the risk of injury to the upper
part of the body.
A fine dust may develop when the airbag de­ ploys . This is normal and does not mean there
is a fire in the vehicle.

216 Fuel supply and filling your fuel tank
-Blend must contain not more than 1S%
MTBE.
Seasonally adjusted gasoline
Many gasoline grades are blended to perform
espec ially we ll for winter or summer driv ing.
During seasonal change-over, we suggest that
you fill up at busy gas stat ions where the sea­
sonal adjustment is more likely to be made in
time.
(CT) 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 fai l to meet the
specified criteria in this chapter.
- If yo u are unable to determine whether
or not a particular fuel blend meets the
specifications, ask your service station or
its fuel sup plier.
- 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 fuel 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.
A lthough gasoline grades differ from one
manufacturer to another, they have certain
things in common. All gasoline g rades contain
substances that can cause deposits to co llect
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 a re not equally effec­
tive .
A udi 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
f uels, carbon deposit build-ups can rob yo ur
engine of peak performance.
(D Note
Damage or malf u nct ion due to poor fuel
quality is not covered by the Aud i New Ve­
hicle Limited Warranty.
Diesel fuel
Applies to veh icles: w ith diesel engine
Always use ULSD (Ultra Low Sulfur Diesel) sul­
fur content 15 ppm or less.
T he ULSD (U ltra Low Sulfur Diesel) meets the
ASTM-D-97S (grade 2).
Diesel fuel with a higher concentration than
ULSD-Diesel No. 2 ASTM 0975 and Bio-die­
sel with a higher concentration than S
% like
B11, B20 or B100 are strictly prohibited.
Serv ice stat ion fue l pumps a re labeled with
the correct fuel information fo r easy recogn i­
t ion by the user. If the diesel fuel pump is not
labeled ask the station operator what fue l is
being dispensed before filling up your vehicle.
Service stations offering Diesel fuel are gener­
ally located on truck routes or major high­
ways. Directories of Diesel fuel stations are
usually available at Diesel fuel stations.
Some states in the USA req uire permits to
purchase Diesel fuel. Check with your State
Motor Vehicle Department.
Diesel fuel may not be ava ilable outside the
USA and Canada. Be sure to check before trav-
eling to other countries . .,..

238 Check ing and filling
- Char ge the bat tery i n a we ll ven tilated
area. Kee p away from open flame or elec­
trical spa rk. Do n ot smoke. Hydrogen gas
generated b y the battery is explosive.
- To reduce the danger of explosion, never
connect or disconnect charger cables
wh ile the charger is operating.
- Fast charg ing a battery is dangerous and
should only be attempted by a compe­
tent technicia n w ith the proper equ ip­
ment.
- Battery acid that may spill during charg­ ing should be washed off wit h a solution
of warm water and baking soda to neu­
t rali ze the acid.
(D Note
Never use a fast charger as a booster to
start the engine. This will se riously dam­
age sensitive elect ronic components, such
as control units, relays, rad io, etc., as we ll
as t he battery charger.
Battery replacement
The new battery must have the same specifi­
c ations and dimensions as the original equip­
ment battery.
Intell igent energy management in your veh i­
cle is respons ible for d istributing the e lectr i­
cal energy throughou t your vehicle
qpage 199. The intel ligen t energy manage­
ment system w ill keep the engine battery
charged better than vehicles without th is sys­
tem. To make sure the additional electrical en­
ergy is available once again after you have
changed the battery, we recommend that you
install batteries of the same type and ma nu­
facture only (the same as those installed at
the time your vehicle was delivered). Specifi­
cations a re listed on the battery ho using. Yo ur
author ized de aler must code the b attery in
the energy management system to enable you
to use the energy management fu nctions cor­
rectly after replacing the battery. T
he new battery must have the same capacity,
vo ltage ( 12-volts), amperage, construction
and plug sea ling.
When ins tall ing t he battery, make su re the ig­
nition and a ll elect rical consume rs are switch ­
ed off.
(D Note
M ake sure the ven tilat ion hose on the side
of the ba ttery is connecte d, otherwise
fumes or batte ry acid can lea k out .
- Veh icles with the Start-S top-System * are
equip ped with a spec ial cycle-proof AGM
battery . Install ing a d iffe rent type of
battery can cause problems in the vehi­
cle e lectr ica l system. Whe n replac ing the
vehicle battery, always install one w ith
the same specifications as the origi na l
battery.
@) For the sake of the environment
Because of the prob lem of proper disposal
of a battery, we recomme nd your author­
i zed Audi dealer change the battery fo r
you. Batteri es contain sulfur ic acid and
l ead and must a lways be di spo sed o f prop­
erly in comp liance wi th all envi ronmental
regulations. Disposing of vehi cle batter ies
imprope rly is very dange rous to the envi­
r onment.

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, particularly considering the compara­
tive ly small patch of rubber on each tire that
assures that all -impo rtant contact between
you, your vehicle and the road.
Maintaining the correct tire pressure, mak ing
sure that your vehicle and its tires do not have
to carry mo re weight than they can safe ly han­
d le, avoiding damage from road hazards and
reg ularly inspecting t ires for damage includ­
ing cuts, slashes irregu la r wear and ove rall
condition are the most important things that
you can do to he lp avoid sudden tire failure in­
cluding tread separation and blowouts.
A voidin g damage
I f you have to drive over a curb or similar ob­
stacle, drive very s low ly and as close as possi ­
b le at a right angle to the curb.
A lways keep chem ica ls includ ing grease, o il,
gasoline and b rake fluid off the ti res.
Inspect the t ires regularly for damage (cuts,
cracks or b listers, etc.). Remove any fo reign
bod ies embedded in the treads.
St oring tires
Mark tires when you remove them to indicate
the direction of rotation . Th is ensures you to
be ab le to mount them correctly when you re­
install t hem.
When removed, the wheels or t ires should be
stored in a cool, dry and preferably dark place .
Store tires in a vertical pos ition if they are not
mounted on rims, in a horizontal pos it ion if
they are mounted on rims. New tire
s
New t ires have to be broken in¢&,. .
T he tread depth of new t ires may vary, accord­
ing to the type a nd make of t ire and the tread
pa tte rn .
Hidden damage
Damage to tires and r ims is often not readily
vis ible . If you notice unusual v ibrat ion or the
vehicle p ulls to one side, th is may ind icate
that one of the t ires has been damaged . Th e
t ir es m ust be checked immed iate ly by an au ­
tho rized Aud i dea le r or q uali fied wor kshop.
Unidirectional t ires
A un idirectional tire can be identified by ar­
rows on the sidewa ll, that po int in the direc­
t ion the t ire is designed to rotate. You must
fol low the specified d irection of rotation . This
is necessary so that these tires can develop
their optimum characteristics regarding grip, road no ise, wear and hydrop laning resistance.
For more information ¢
page 268.
A WARNING
-New tires or tires that are old, worn or
damaged cannot provide maximum con­
trol and braking ability .
-
-New tires tend to be slippery and must
be broken in . To reduce the risk of losing
control, a co llision and ser ious personal
in jur ies, d rive w ith special ca re fo r the
fi rst 350 m iles (560 km).
- Driving with worn or damaged tires can
lead to loss of control, sudden tire fail­
ure, including a blowou t and sudden de­
fl ation, c rashes and seriou s personal in­
juries . Have wo rn or damaged t ires re­
p laced immediate ly .
- T ires age even if they are not being used
and can fai l sudden ly, especially at high
speeds. Tires that are more than 6 years
old can only be used in an emergency
and then w ith specia l care and at low
speed.

unbalanced, resulting in vib rations you can
usually feel through the steering wheel.
Unba lanced wheels mus t be rebalanced to
avoid excessive wea r on s teer ing, suspens ion
and tires. A wheel must a lso be rebalanced
when a new tire is installed.
Incorrect wheel alignment
Inco rrect whee l alignment can cause exces­
sive tire wea r, impair ing t he safety of the veh i­
cle. If t ires show excess ive wear, have the
wheel alignment checked by an authorized
Audi dealer or qualified workshop.
All-wheel d rive
Ve hicles w it h quattro must always have tires
of the s ame s ize, construction and tread type.

A WARNING
Sudden tire failure can lead to loss of con­
trol, a crash and serious persona l injury!
- Never drive a veh icle when the tread on
any t ire is worn down to the wear indica­
tors.
- Worn tires are a safety hazard , they do
not grip well on wet roads and increase
your risk of"hydrop lan ing" and loss of
co ntrol.
- 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
sp eeds.
- Never mount used tires on yo ur vehicle if
yo u are not sure of their "previous histo­
ry." Old used ti res may have been dam­
aged even though the damage cannot be
seen that can lead to s udden tire failure
and loss o f vehicle control.
