& WARN ING (continued )
• Always make sure that the side airbag can inflate without inter­
fe rence :
- Never install seat covers or replacement upholstery over the
front seatback s that have not been spe cifically approved by
Audi.
- 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 airbag module must always be repaired immedi ­
ately by an authorized Audi dealer .
• The airbag system can be activated only once. After an airbag
ha s inflated , it must be replaced by an authorized Audi de aler 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 repla ced with new repla cement
parts designed and approved especially for your Audi model
version . Replacement of complete airbag systems or airbag
components must be performed by qualified workshops only .
Make sure that any airbag service action is entered in your Audi
Warranty
& Maintenance booklet under AIRBAG REPLACEMENT
RECORD .
• Applies to vehicles with 6 -cylinder engine : For safety reasons in
severe accidents , the alternator and starter are separated from the
vehicle battery with a pyrotechnic circuit interrupter .
- Work on the pyrotechni c circuit interrupter must only be
performed by a qualified dealer -risk of an accident!
- If the vehi cle or the circuit inte rrupter is scrapped , all appli ­
cable safety precautions must be followed. •
Other things that can affect Advanced Airbag
performance
Changing the vehic le 's suspens ion system can change the way that
th e Adva nced Air bag Syste m performs in a c rash. Fo r example,
using tire -ri m co mbinations not approved by Audi, lowering the
veh ic le, c hang in g the st if f ness o f th e suspe nsio n, incl uding th e
spr ings, suspension struts, shock absorbers etc. can change the
f o rces t hat a re m easured by the a irba g se nsors and se nt to the elec ­
tronic control unit. Some suspension changes can, for example,
i ncrease the fo rce level s meas ure d by the senso rs and make the
a irbag system dep loy in crashes in which it wou ld not d ep loy if the
changes ha d no t been made . O th er ki nds of changes may red uce
th e force levels measured by the sensors and preve nt the airbag
fro m deploying w hen it sh ould.
Th e senso rs in th e sa fety belt buc kle fo r the dr iver a nd fro nt
passenger seat te ll the e lectronic control modu le if the safety belt is
l a tc h ed or not . If th e sa fe ty belt is being use d, th e front airbag wi ll
deploy at a slightly higher rate of vehic le dece leration than if the
sa fe ty be lt is n ot b ein g use d. Th ere fore, i n a partic ula r co llisi on, i t is
possible that an airbag wi ll not deploy at a seating position where
th e sa fe ty be lt is bei ng us ed bu t wi ll infl ate at the position w here the
safety be lt is not being used . It is important that nothing interfere
with the safety belt buc kles so that the sensors can send the co rrect
i nformation about safety be lt use to t he electronic contro l unit.
& WARNING
Changing the vehicle's suspension including use of unapproved
tire -rim combinations can change Advanced Airbag performance
and increase the risk of serious personal injury in a crash.
• Never install suspension components that do not have the
same pe rformance characteristics as the components originally
installed on your vehicle.
• Never use tire -rim combinations that have not been approved
by Audi. ..

Engine oil
Engine oil specifications
The engine oil used in your Audi needs the right kind of
oil.
The engine in your Audi is a sophisticated powerplant that was built
to exacting specifications . This engine needs the right kind of
engine oil that meets specifications regarding quality and viscosity
so that it can run smoothly and reliably. Choosing the right oil and
changing oil within the time and mileage intervals printed in your
vehicle's Warranty
& Maintenance booklet matters a lot more today
than it did years ago. Audi has developed a special quality standard
for engine oil that will help assure that your vehicle's engine will get
the lubrication it needs for proper operation .
Modern engine lubrication has taken a quantum leap in the last few
years. Many synthetic oils available today provide better engine
lubrication that can outlast traditional petroleum-based oils,
making them a smart choice for use throughout the life of your Audi .
Whether you use synthetic or petroleum-based engine oil, the oil
that you use must conform to Audi's oil quality standard VW 502 00
to help keep your vehicle's engine running smoothly and help

Changing brake fluid
Have the brake fluid changed by an experienced techni­
cian.
Brake fluid absorbs moisture from the ai r. If the water content in the
brake fluid is too high, corrosion in the brake system may result
after a period of time. The boiling point of the brake fluid wil l also
decrease considerably and decrease braking performance .
Therefore, the brake fluid must be changed
e ver y two years. Always
use new brake fluid which conforms to Federa l Motor Vehicle Stan ­
dard "FMVSS 116 DOT 4" .
The brake fluid reservoir can be difficu lt to reach , therefore, we
recommend that you have the brake fluid changed by your autho­
rized
Audi d ealer. Your dealer has the correct tools, the right brake
fluid and the know-how to do this for you.
& WARNING
• Bra ke fluid i s poisonous . It mu st be stored on ly in the close d
ori ginal container out of the rea ch of children!
• Bra ke fa ilure can result from old or inappropri ate brake fluid .
Observe the se pre caution s:
- Use o nly brake fluid that meets SAE spe cifi ca tion
J 170 3 and
c onform s to Fed era l Moto r Vehic le Sta nda rd 116 . Always c heck
w ith your authori zed Audi de aler to m ake sure you are using
the correct brake fluid. The corr ect type of brake fluid i s als o

Winter op eration
During the winter months, battery capacity tends to decrease as
temperatures drop. This is because more power is a lso consumed
while starting, and the headlights, rear window defogger, etc., are
use d more often .
Avoid unnecessary power consumption, particularly in city traffic or
wh en trave ling on ly shor t distances . Let you r au thor ize d Audi dea ler
check the capacity of the vehicle battery before winter sets in
