There are some important things you have to know to make sure that the effectiveness of
the system will not be impaired and that dis
carded components do not cause injury or pol
lute the environment.
A WARNING
Improper care, servicing and repair proce
dures can increase the risk of personal in
jury and death by preventing an airbag from deploying when needed or deploying an airbag unexpectedly:
- Never cover, obstruct, or change the
steering wheel horn pad or airbag cover
or the instrument panel or modify them
in any way.
- Never attach any objects such as cu
pholders or telephone mountings to the
surfaces covering the airbag units.
- For cleaning the horn pad or instrument
panel, use only a soft, dry cloth or one
moistened with plain water. Solvents or
cleaners could damage the airbag cover
or change the stiffness or strength of the
material so that the airbag cannot de
ploy and protect properly.
- Never repair, adjust, or change any parts
of the airbag system.
- All work on the steering wheel, instru
ment panel, front seats or electrical sys
tem (including the installation of audio
equipment, cellular telephones and CB
radios, etc.) must be performed by a
qualified technician who has the training
and special equipment necessary.
- For any work on the airbag system, we
strongly recommend that you see your
authorized Audi dealer or qualified work
shop.
- Never modify the front bumper or parts
of the vehicle body.
- Always make sure that the side airbag
can inflate without interference:
- Never install seat covers or replace
ment upholstery over the front seat
backs that have not been specifically
approved by Audi.
Airbag system 171
-Never use additional seat cushions that
cover the areas where the side airbags
inflate.
- Damage to the original seat covers or
to the seam in the area of the side air
bag module must always be repaired
immediately by an authorized Audi
dealer.
- The airbag system can be activated only
once. After an airbag has inflated, it
must be replaced by an authorized Audi
dealer or qualified technician who has
the technical information, training and
special equipment necessary.
- The airbag system can be deployed only
once. After an airbag has been deployed, it must be replaced with new replace
ment parts designed and approved espe
cially for your Audi model version. Re placement of complete airbag systems
or airbag components must be per
formed by qualified workshops only.
Make sure that any airbag service action
is entered in your Audi Warranty
& Main
tenance booklet under
AIRBAG REPLACE
MENT RECORD.
- In accidents when an airbag is deployed,
the vehicle battery separates the alterna
tor and the starter from the vehicle elec
trical system for safety reasons with a
pyrotechnic circuit interrupter.
- Work on the pyrotechnic circuit inter
rupter must only be performed by a
qualified dealer - risk of an accident!
- If the vehicle or the circuit interrupter
is scrapped, all applicable safety pre
cautions must be followed.

dealer is familiar with these requirements
and we recommend that you have your
dealer perform this service for you.
Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced Airbag Sys
tem performs in a crash. For example, using
tire-rim combinations not approved by Audi, lowering the vehicle, changing the stiffness of
the suspension, including the springs, suspen
sion struts, shock absorbers etc. can change
the forces that are measured by the airbag
sensors and sent to the electronic control
unit. Some suspension changes can, for exam ple, increase the force levels measured by the
sensors and make the airbag system deploy in
crashes in which it would not deploy if the
changes had not been made . Other kinds of
changes may reduce the force levels meas
ured by the sensors and prevent the airbag
from deploying when it should.
The sensors in the safety belt buckle for the
driver and front passenger seat tell the elec
tronic control module if the safety belt is
latched or not.
If the safety belt is being used,
the front airbag will deploy at a slightly high
er rate of vehicle deceleration than if the safe
ty belt is not being used. Therefore, in a par
ticular collision, it is possible that an airbag
will not deploy at a seating position where the
safety belt is being used but will inflate at the
position where the safety belt is not being
used. It is important that nothing interfere
with the safety belt buckles so that the sen
sors can send the correct information about
safety belt use to the electronic control unit.
A WARNING
Changing the vehicle's suspension includ
ing use of unapproved tire-rim combina
tions can change Advanced Airbag per
formance and increase the risk of serious
personal injury in a crash.
- Never install suspension components
that do not have the same performance characteristics as the components origi
nally installed on your vehicle.
- Never use tire-rim combinations that
have not been approved by Audi.
A WARNING
= -
Items stored between the safety belt
buckle and the center console can cause
the sensors in the buckle to send the
wrong information to the electronic con
trol module and prevent the Advanced Air
bag System from working properly.
- Always make sure that nothing can inter
fere with the safety belt buckles and that
they are not obstructed.
Side airbags
Description of side airbags
The airbag system can provide supplemental
protection to properly restrained occupants.
Fig. 170 S ide a irbag location in the driver's seat
The side airbags are located in the sides of the
front seat backrests¢
fig. 170 and the rear
backrest* facing the doors. They are identified
by the word "AIRBAG".
The side airbag system basically consists of:
-the electronic control module and external
side impact sensors
- the two airbags located in the sides of the
front backrests and the two airbags* located
in the rear backrest
- the airbag warning light in the instrument
cluster.
The airbag system is monitored electronically
to make certain that it is functioning properly ..,.

206 Driving and en vir onm ent
Catalytic converter
It is very important that your emission con
trol system (catalytic converter) is function
ing properly to ensure that your vehicle is run
ning in an environmentally sound manner .
• Always use lead-free gasoline¢ page 228,
Fuel supply.
• Never run the tank down all the way to
empty .
• Never put too much motor oil in your en-
gine ¢
page 238, Adding engine oil~-
., Never try to push- or tow -start your veh icle.
The catalytic converter is an eff ic ient "clean
up" device built into the exhaust system of
the vehicle. The catalytic converter burns many of the pollutants in the exhaust gas be
fore they are released into the atmosphere.
The exclusive use of unleaded fuel is critically
important for the life of the cata lytic conve rt
e r and proper functioning of the engine.
& WARNING
-
- Do not park o r operate the vehicle in
areas where the hot exhaust system may
come in contact with dry grass, brush,
fuel spill or other material which can cause a fire.
- Do not apply additional undercoating or
rustproofing on or near the exhaust
man ifold, exhaust p ipes, catalytic con
verter or heat shields . During driving, the
substance used for undercoating could
overheat and cause a fire .
@ Note
-Be aware that just one tank filling with
leaded fuel will already seriously de
grade the performance of the catalytic
conve rter .
- Do not exceed the correct engine oil level
¢ page 238.
-Do not drive until the fuel tank becomes
completely empty. The eng ine could mis
fire . U nburned f uel could a lso get into the exhaust system and this co
uld cause
the cata lytic converter to overheat .
- Do not turn off the ignition while the ve
hicle is moving.
- Do not continue to ope rate your veh icle
under these conditions, as otherwise fuel
can reach the catalytic converter. This
cou ld result in overheating of the con
verter, requir ing its replacement.
- To assure efficient operation of the Emis
sion Control System:
- H ave your vehicle maintained properly
and in accordance w it h the service rec
ommendat ions in your Warranty &
M ain tenance book let.
- L ack of prope r maintenance as we ll as
improper use of the vehi cle will impair
the function of the em iss ion contro l
system and could lead to damage .
@ For the sake of the environment
Even when the Emiss ion Control System is
operat ing proper ly, the exha ust gas can
have a sul fur -li ke exhaust gas smell under
some operating states . This depends on
the sulfur content of the fuel being used .
Using a different brand of fue l may help,
or f il li ng the tank with lead-free super
grade gasoline .
Avoid damaging the
vehicle
When you are d rivi ng on poor roads, or over
c u rbs, steep ramps, etc., ma ke certai n that
low- ly ing parts s uch as spoilers and exha ust
system parts do not bottom o ut and get dam
aged.
T his is espe cially true for ve hicles with low
s lung chassis (spor ts chassis)* and fully load
ed vehicles .

208 Driving and environment
would go unheeded. Extended idling also
produces heat, which could result in over heating or other damage to the vehicle or
other property .
Regular maintenance
A badly tuned engine unnecessarily wastes a
lot of fuel .
• Have your vehicle serviced at regular inter-
vals.
By having your vehicle regularly serviced by an
authorized Audi dealer helps to ensure that it
runs properly and economically. The condition
of your vehicle not only affects its safety and
ability to hold its value, it also affects
fuel
consumption.
Check your oil each time you fill your tank.
The amount of oil used is related to engine
load and speed.
It is normal for the oil consumption of a new
engine to reach its lowest value after a certain mileage has been driven .
You must drive your vehicle about 3,000 miles (5,000 kilometers) before you can properly
assess oil consumption .
This also applies to fuel consumption and en
gine output .
{Q) Note
-Have your vehicle maintained properly
and in accordance with the service rec
ommendations in your Warranty
& Main
tenance booklet. Lack of proper mainte
nance as well as improper use of the ve
hicle will impair the function of the
emission control system and could lead
to damage.
- Do not alter or remove any component of
the Emission Control System unless ap
proved by the manufacturer.
- Do not alter or remove any device, such
as heat shields, switches, ignition wires,
valves, which are designed to protect
your vehicle's Emission Control System and
other important vehicle compo
nents.
Fewer short trips
Fuel consumption will always be relatively
high on short trips.
• Try to avoid driving short distances with a
cold engine.
The engine and catalytic converter have to
reach their optimal
operating temperature to
reduce fuel consumption and noxious emis
sions effectively.
Just after starting, a cold engine in a mid-size
car only achieves a fuel economy of 6-8 miles
per gallon (30-40 l/100 km). After about a
half a mile , fuel economy climbs to 12 mpg
(20 l/100 km). After about
2.5 miles (4 km),
the engine is at its proper operating tempera
ture and fuel economy has reached a normal level. So you can see that you should avoid
short trips whenever possible .
T he
outside temperature is also critical in this
regard. Your car consumes more fuel in the
winter than in the summer .

-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 stat ions where the sea
sonal adjustment is more likely to be made in
time.
(D Note
- Fuels containing a high percentage of
ethanol such as ESO and E85 may only
be used in veh icles with flex ible fuel* en
gines. Using high ethano l fuel in vehicles
not equipped with flexib le fue l* engines
can cause severe engine damage .
- 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 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 respons ibility of Audi and are not
covered under the New Veh icle 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.
Fuel supply and filling your fuel tank 229
Ethanol fuel (Bio-ethanol)
Applies to veh icles: w it h flex ible fue l en gin e
You can recognize vehicles with a flexible fuel
engine by looking at the label on the inside of
the fuel filler flap .
Vehicles with flexible fuel engines may be op
erated with bio -ethanol fuels such as E85
(85% ethanol and 15% gasoline) or with un
leaded gasoline (91 AKI/ROZ 95) . T he vehicle
may also be operated with a mixture of these
fuels.
Your fuel consumption will increase when us
ing bio-ethanol fue ls due to the lower amount
of energy contained per unit volume in etha
nol.
Warming up the flexible fuel engine in
low temperatures
Due to the chemical composition of b io-etha
nol, a certain amount of fuel ends up in the
engine oil when driving short distances in ve ry
low temperatures. This fuel evaporates again
when the engine is warmed up.
D Please warm up engine.
If the driver message appears in the instru
ment cluster disp lay, drive with a warm en
gine to reduce the oil level.
(D Note
- Never fill with methanol or with a higher
percentage of b io-ethanol than 85%
(E85). A h igher percentage of bio-etha
nol in the fuel can cause damage to the
engine or to the fue l system.
- If you use only E85, it is recommended
to fill the fue l tank complete ly w ith un
leaded premium grade gaso line every
5,000 miles.
- If you experience starting, rough id le or
hesitation driveability problems, fill the
fuel tank comp letely with unleaded pre
mium grade gasoline and dr ive it nor
mally until the gasoline is used. See your
authorized Audi dealer if the problem
pers ists.

Changing the engine oil
We recommend that have your oil changed by
an authorized Audi dealer or a qualified serv
ice station.
Before you check anything in the engine com
partment,
a lways rea d and he ed all WARN
INGS
~ &. in Working in the engine compart
ment on page 233.
The engine oil must be changed according to
the intervals specified in your Warranty
&
Maintenance book let. This is very important
because the lubricating properties of oil di
minish gradua lly during normal vehicle use.
Under some circumstances the engine oi l
should be changed more frequently. Change
oil more often if you drive most ly short dis
tances, operate the vehicle in dusty areas or under predominantly stop-and-go traff ic con
d itions, or have your veh icle where tempera
tures remain below freezing for extended pe
riods.
Detergent additives in the o il w ill make fresh
oil look dark after the engine has been run n ing for a short time. This is normal and is not
a reason to change the oil more often than recommended.
Because of the problem of proper disposa l,
along w ith the special tools and necessary ex
pertise required, we strongly recommend that
you have you r oi l changed by an authorized
Au di de ale r o r a qual ified servi ce station.

Tires and vehicle load limits
There are limits to the amount of load or
weight that any veh icle and any t ire ca n car ry.
A vehicle that is overloaded w ill not ha ndle
well a nd is more difficult to stop. Over load ing
can not on ly lead to loss of vehicle contro l,
but can a lso damage important parts of the
ve hicle and can lead to sudden tire failure , in
cluding a blowout and sudden deflation that
can cause the veh icle to crash .
Your safety and that of yo ur passenge rs a lso
depends on making sure that load limits are not exceeded. Vehicle load includes everybody
a nd everyth ing in and on the vehicle . T hese
load limits are tech nica lly refe rred to as the
