Improper seating positions reduce the effective ­
ness of safety be lts and will even increase the
risk of injury and death by mov ing the safety belt
to critical areas of the body. Improper seating positions also increase the risk of serious injury
and death when an airbag deploys and strikes an
occupant who is not in the correct seat ing pos i­
tion . A driver is respons ible for the safety of a ll
vehicle occupants and espec ia lly for children.
Therefore:

A WARNING
Improperly worn safety belts increase the risk
o f serious personal injury and death whenever
a vehicle is being used .
- Always make sure tha t all vehicle occupants
are correctly restrained and stay in a correct
seating position whenever the vehicle is be­
ing used.
- Always read and heed all WARNINGS and

Belt tensioners
How safety belt pretensioners work
In front, side and rear-end collisions above a
particular severity and in a rollover , safety belts
are tensioned automatically .
Reversible safety belt ten sioners
The safety belts on the front seats are equipped
with power reversible tensioners. The following
functions are available when the driver's/front passenger's safety belts are fastened:
- In certain driving situations, the safety belts
may tighten with a reversible tens ion ing func­
t ion
i::>page 133 .
- The safety belts may a lso tighten with this re­
versib le tensioning function in minor collis ions.

verity and in a rollover. This tightens the belt and
takes up belt
slack ¢&. in Service and disposal of
safety belt pretensioner on page 266.
Taking up
the slack helps to reduce forward occupant movement during a collision.
A WARNING Co---
- It is poss ible for the pretensioners to deploy
i n correctly.
- The pyrotechnic system can only provide
protection for one collision. If the pyrotech­
n ic pretens ioners deploy, the pretensioning
sys tem must be replaced.
@ Tips
The pyrotechn ic safety belt pretensioners can
o nly deploy once.
- The safety belt pretensioners do not deploy
in minor frontal, side and rear-end colli­
sions .
- A fine dust is re leased when the pyrotechnic
safety belt pretensioners deploy . This is nor­
mal and is not caused by a fi re in the ve hi­
cle.
- The relevant safety requirements must be
observed when the vehicle or components
of the system are scrapped. A q ualified
dealership is familiar with these regulat io ns
and wi ll be pleased to pass on the informa ­
tion to you.
- Be sure to observe all safety, envi ronment al
and other regulat ions if the vehicle or in di­
vidua l parts of the system, particularly the
safety belt or airbag, are to be disposed . We
recommend you have yo ur authorized Aud i
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 examp le, using tire-r im
combinations not approved by Audi, lowering the
vehicle, changing the stiffness of the suspension, 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 suspens ion changes
can, for example, increase the force levels meas­
ured by the sensors and make the airbag system
deploy in crashes in wh ich it would not dep loy if
t he changes had no t been made. Other kinds of
changes may reduce the force levels meas ured by
the sensors and prevent the airbag from deploy­ ing when it should.
.&_ WARNING
Changing the vehicle 's s uspension incl uding
use of unapproved tire-rim combinations can
change Advanced A irbag performance and in-
Airb ag sys tem
crease the risk of serious personal injury in a
crash.
- Never install suspension components that
do not have the same performance charac­
ter istics as the components originally instal­
led on your vehicle.
- Never use tire-rim combinations that have
not been approved by Audi.

Gasoline additives
A ma jor concern among many auto manufactur­
ers is carbon deposit build-up ca used by the type
of gasoline yo u use.
A lt hough gasoline grades d iffer from one manu ­
facturer to another, they have cer tain things in
common . A ll gasoline grades contain substances
that can cause deposits to collect on vita l engine
parts, such as fue l injectors and intake valves.
Al­
though most gasoline brands include additives to
keep engine and fuel systems clean, they are not
equally effective .
Aud i recommends using TOP TIER Detergent Gas­
oline. For more informat ion on TOP TIER Dete r­
gent Gasoline, please go to the official website
(www.toptiergas .com) .
After an extended period of using inadequate
fuels, carbon deposit build-ups can rob your
en­
g ine of peak performance.

Checking and Filling
CJ) Note
-The engine oil level must not be under the
marking
(D r=> fig. 272, because this increas­
es the risk of engine damage.
- After adding engine oil, the oil level must
not be above the marking
@ c:> fig . 2 72, be­
cause this increases the risk of catalytic con­
verter and/or engine damage. Do not start
the engine. Contact an authorized Audi
dealer or authorized Audi Service Facility to
have excess engine oil extracted if necessa­
ry .
- Do not mix any additional lubricants into
the engine oil. Damage caused by such addi­
tives is not covered by the warranty .
@ For the sake of the environment
-Engine oil 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.
@ Tips
The engine oil consumption may be up to
0 .S quart/600 miles (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 drives.
Changing the engine oil
We recommend that hove your oil changed by on
authorized Audi d eal er or o qualified s ervice sta­
tion.
Before you check anything in the engine compart­
m ent,
always read and heed all WARNINGS
r=> page 316.
The engine oil must be changed according to the
intervals specified in your Warranty
& Mainte­
nance bookl et. This is very important b ecause the
lubric ating properties of oil diminish gradually
during normal vehicle use.
322
Under some circumstances the engine oil should
be changed more frequently. Chang e oil more of­
ten if you drive mostly short distances, operate
the vehicle in dusty areas or under predominantly
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
look dark 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 proper disposal, along
with the special tools and necessary expertise re­
quired, we strongly recommend that you have
your oil changed by an authorized
Audi dealer or
a qualified service station .
If you choose to change your oil yourself, please
note the following important information :
,&. WARNING
To reduce the risk of personal injury if you
must change the engine oil in your vehicle
yourself:
- Wear eye protection.
- To reduce the risk of burns from hot engine
oil , let the engine cool down to the touch.
- When removing the oil drain plug with your
fingers, stay as far away as possible . Always
keep your forearm parallel to the ground to
help prevent hot oil from running down your
arm.
- Drain the oil into a container designed for
this purpose, one large enough to hold at
least the total 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 .
0 Note
Never mix oil additives with your engine oil.
These additives can damage your engine and
adversely affect your Audi Limited New Vehi­
cle Warranty .
