whenever the ignition is switched on.
A WARNING
- If the PASSENGER AIR BAG OFF light does
not go out when an adult is sitting on the
front passenger seat after taking the steps described above, make sure the adult is
properly seated and restrained at one of the
rear seating positions .
- Have the airbag system inspected by your
authorized Audi dealer before transporting
anyone on the front passenger seat.
{D) Tips
If the weight -sensing mat in the front passen ­
ger seat detects an empty seat, the front air­
bag on the passenger side will be turned off,
and
PASSENGER AIR BAG OFF will stay on.
Repair, care and disposal of the airbags
Parts of the airbag system are installed at many
different places on your Audi. Installing, remov­
ing, servicing or repairing a part in an area of th e
vehicle can damage a part of an airbag system and prevent that system from working properly in a collision .
There are some important things you have to know to make sure that the effectiveness of the
system will not be impaired and that discarded
components do not cause injury or pollute the
environment.
A WARNING
Improper care, servicing and repair proce­
dures can increase the risk of personal injury
and death by preventing an airbag from de­
ploying when needed or deploying an airbag
unexpectedly:
-
- Never cover, obstruct, or change the steer­
ing wheel horn pad or airbag cover or the in­
strument panel or modify them in any way.
- Never attach any objects such as cupholders
or telephone mountings to the surfaces cov­
ering the airbag units.
Airbag system
-For cleaning the horn pad or instrument
panel, use only a soft, dry cloth or one mois­
tened 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 deploy and protect
properly.
- Never repair, adjust, or change any parts of
the airbag system.
-All work on the steering wheel, instrument panel, front seats or electrical system (in­
cluding 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 au­
thorized Audi dealer or qualified workshop.
- 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 replacement
upholstery over the front seatbacks that
have not been specifically approved by
Audi .
- Never use additional seat cushions that
cover the areas where the side airbags in­
flate.
- Damage to the original seat covers or to
the seam in the area of the side airbag
module must always be repaired immedi­
ately 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 replacement
parts designed and approved especially for
your Audi model version. Replacement of complete airbag systems or airbag compo ­
nents must be performed by qualified work-
shops only. Make sure that any airbag

REPLACEMENT RECORD.
@ For the sake of the environment
Undeployed airbag modules and pretension­
ers might be classified as Perchlorate Materi­
al -special handling may apply, see
www.dtsc.ca.gov/hazardouswaste/perchlo­
rate. When the vehicle or parts of the re­
straint system including airbag modules safe­
ty belts with pretens ioners are scrapped, al l
applicable laws and regulat ions must be ob­
served. Your authorized Audi dealer is familiar
with these requ irements 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 System
performs in a crash. For examp le, using t ire-rim
combinations not approved by Audi, lower ing the
veh icle, changing the stiffness of the suspens ion,
including the springs , suspension 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 example, increase the force levels meas­
ured 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 measured by
the sensors and prevent the airbag from deploy­
ing when it should .
A WARNING
Changing the vehicle's suspension including
use of unapproved tire-rim combinations can
change Advanced Airbag performance and in ­
crease the risk of serious personal in jury in a
crash.
- Never install suspension components that
do not have the same performance charac­
teristics as the components originally instal­
led on your veh icle .
128
.
-Never use tire-rim combinations that have
not been approved by Aud i.
A WARNING
Items stored between the safety belt buckle
and the center conso le can cause the sensors
in the buckle to send the wrong information
to the electronic control module and prevent
the Advanced A irbag System from wo rking
p roperly.
-Always make sure that nothing can interfere
w ith 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. 116 Sid e a irbag locatio n in the dr ive r's seat
The side airbags are located in the s ides of the
front seat backrests
~ fig . 116 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
- the airbag warning light in the instrument clus-
ter.
The airbag system is mon itored electron ically to
make certain that it is functioni ng properly at a ll
times. Each time you turn on the ignition, the air ­
bag system indicator light will come on for a few
seconds (self diagnostics). .,,_

The correct gasoline grade is stated on the inside
of the fuel filler door .
The vehicle is equipped with a catalytic converter
and must only be driven w ith
unleaded ga soli ne.
Aud i recommends using TOP TIER Detergent Gas­
oline. Additional information on TOP TIER Deter­
gent Gaso line can be found on the offic ial web­
site (www .toptiergas.com) .
The individua l gasoline grades are differentiated
by
octane ratings . This value is given with (R +M)/

Using the prope r engine oil is important for the
functionality and s ervice life of the engine. Your
engine was factory-filled with a high -quality oil
which can usually be used throughout the entire
year .
Note
Your Limited New Vehicle Warranty does not
cover damage or malfunctions due to failure
to follow recommended maintenance and use
requirements as set forth in the Audi Owner's Manual and Warranty & Maintenance booklet .
- Use only a high quality engine oil that ex-
pressly complies with the Aud i oil quality
standard specified for your vehicle's engine.
Using any o ther oil can cause serious engine
damage.
- Do not mix any lubricants o r other additives
into the engine oil. Doing so can cause en­
gine damage.
@ Tips
If you need to add oil and there is none availa­
ble that meets the Audi o il quality standard
your eng ine requ ires, you may add a total of
no more than 0 .5 quart/li ter of a h igh-quality
"synthet ic"oil that meets the following speci ­
fications.
- ACEA A3 or API SM with a v iscosity grade o f
SAE OW-30, SAE SW -30 or SAE SW-40.

Engine oil consumption
T he engine in your vehicle depends on an ade­
qua te amoun t of oil to lubricate and cool all of
i t s moving par ts.
In order to provide effective lub rication and coo l­
ing of in te rnal engine components, a ll internal
combustion engines consume a cer tain amount
of oil. Oil consumption varies from engine to en ­
g ine and may change sign ificantly over the life of
the eng ine . Typically, eng ines with a spec ified
Ch eck ing and Filling
break-in period (see ¢ page 57) consume more
oi l during th e break-in period than they consume
after oil consumption has stabilized.
Under normal cond itions, the rate of oil con­
sumption depends on the q uality and viscos ity o f
the oil , the RPM (revolutions per minut e) at
which the engine is operated, the amb ient tem­
perature and road condit ions. Further factors are
the amount of oil dilution from w ater condensa­
tion or fuel resid ue and the oxidation level of the
o il. As any engine is subject to wear as mileage
builds up, the oi l consumption may increase ove r
t ime unt il repla cement of worn components may
become necessary.
With al l these variables coming into play, no
standard rate of o il consumption can be estab­
l ished or spec ified . T he re is no alte rnative to reg­
u la r and fre quent chec king of the o il level , see
Note .
If the yellow engine oil level warning symbo l II
in the instrument cluster lights up , you sho uld
check the o il level as soon as possible
¢ page 160. Top off the o il at your earliest con­
venience.
A WARNING
Before you check anything in the engine com­
partment, always read and heed all WARN ­
INGS¢ .&.
in Working in the engine compart­
ment on page 155.
(D Note
D riving wit h an insufficient oil level is likely to
cause severe damage to the engine .
(D Tips
- The oil pressure warn ing display. i s not
an indicato r of the o il le vel. Do not rely on
it . Instead, check the oil level in your en ­
gine at regular intervals , pre fe rabl y each
time you refuel, and alw ays befo re go ing
on a long trip .
-If you have the impression your engine con­
sumes excessive amounts of oi l, we recom­
mend that you consult an author ized Audi
dea ler to have the cause of your concern

@ Fo r the sa ke of the env ironment
- Engine oi l should never enter the sewer sys­
tem or come into contact with the ground
under any circumstances.
- Pay attention to legal requirements when
disposing of empty oil containers.
The engine oil consumption may be up to 0.5 quart/600 m iles (0.5 liter/1,000 km), de­
pending on driving style and operating condi­
tions. Consumption may be higher during the
first 3,000 miles (5,000 km). The engine oil
level must be checked regularly . It would be
best to check each time you refuel your vehi­
cle and before long dr ives.
Changing the engine oil
We recommend that have your oil changed by an
authorized Audi dealer or a qualified service sta­
tion.
Before you check anyth ing in the eng ine compart­
ment,
alw ays r ea d and heed all WARNINGS Q .&.
in Working in the engine compartment on
page 155.
The engine oil must be changed according to the
intervals specified in your Warranty
& Mainte­
n ance booklet. This is very important because the
l ubri cat ing propert ies of o il diminish gradually
d ur ing normal vehicle use.
Under some c ircumstances the eng ine o il should
be changed more frequently . Change oil more of­
ten if yo u drive mostly short distances, ope rate
the vehicle in d usty areas or under predominant ly
stop-and -go traffic conditions, or have your vehi­
cle where temperatures remain below freezing
for extended periods.
Detergent additives in the oil will make fresh oil
l ook da rk after the engine has been running 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 p roper disposal, along
with the special tools and necessa ry expertise re­
qu ired, we strong ly recommend that you have
Ch eck ing and Filling
your oi l changed by an authorized Audi dealer or
a qualified service station .
If yo u choo se to ch ange yo ur oil your self, please
note the follow ing important info rmation:
A WARNING
=
To reduce the risk of persona l injury if you
must change the engine oil in your vehicle
yourself:
- Wear eye protect ion .
-
-To redu ce the r is k of burns from hot eng ine
oil, let the engine cool down to the touch.
- W hen remov ing the oil d rain plug w ith your
fingers, stay as far away as possib le. Always
keep your forearm parallel to the ground to
he lp prevent hot oil from running down your
arm.
- Drain the oil into a container designed for
this purpose, one la rge enough to hold at
least the tota l amount of oil in your engine.
- Engine oil is poisonous. Keep it well out of
the reach of children.
- Continuous contact with used engine oil is
harmful to your skin. Always protect your
skin by washing oil off thoroughly with soap
and water.
(D Note
Never mix oil additives with your engine oil.
These additives can damage your engine and
adverse ly affect yo ur Audi Limited New Vehi­
cle Warranty.
@ For the sa ke of the environment
- Before chang ing your oi l, first make sure
you know where you can properly d ispose of
the used oil.
- Always dispose of used engine o il properly.
Do not dump it on garden soil, wooded
areas, into open streams or down sewage
drains.
- Recycle used engine o il by tak ing it to a used
eng ine oil collection fac ility in your area, or
contact a service station .

To reduce the risk of lime scale deposits on the
spray nozzles, use clean water with low amounts
of calc ium . Always add window cleaner to the wa­
ter. When the outside temperatures a re cold, an
anti-freezing agent should be added to the water
so that it does not freeze.
- The concent ration of anti-freezing agent
must be adjusted to the vehicle operating
conditions in the respective climate. A con­
cent ration that is too high can lead to vehi­
cle damage.
- Never add radiator anti-freeze or other addi­
tives to the washer fluid.
- Do not use a glass cleaner that contains
paint solvents, because this could damage
the paint .
