Incorrectly positioned safety belts can cause se­
vere injuries .
Wearing safety belts improperly can cause seri­
ous injury or death. Safe ty belts can only work
when they are correctly posit ioned on the body .
Improper seating pos it ions reduce the effective­
ness of safety belts and will even inc rease the risk
of injury and death by moving the safety be lt to
cr itica l areas of the body . Improper seati ng posi­
tions a lso increase the risk of serious injury and
death when an airbag deploys and strikes an oc­
cupant who is not in the correct seating position.
A driver is responsible for the safety of all vehicle
occupants and espec ially for children. Therefore :

Belt tensioners
How safety belt pretensioners work
In front, side and rear-end collisions above a
particular sev erity, saf ety belts are tensioned au­
tomatically .
The safety belts are equipped with safety belt
pre tensioners. The system is act ivated by sensors
in front, side and rear-end collisions o f great se ­
verity. This tightens the belt and takes up belt

Taking up the slack
helps to reduce forward occupan t movement dur­
i ng a collision .
@ Note
Never let the belt remain over a rear seatback
that has been folded forward.
@ Tips
The safety belt pretensioner can only be acti­
vated once.
- In minor frontal and side collisions, in rear­
end co llisions and in accidents involving
very little impact force, the safety belt pre­
tensioner are not activated.
- When the safety belt pretensioners are acti­ vated, a fine dust is released . This is normal
and is not caused by a fire in the vehicle .
- The re levant safety requirements must be
observed when the vehicle or components
of the system are scrapped. An authorized
Audi dealer or qua lified workshop is familiar
with these regulations a nd will be pleased
to pass on the information to yo u. ...

Service and disposal of safety belt preten­
sioner
The safety belt pretensioners are parts of the
safety belts on your Audi. Installing, removing ,
servicing or repairing of belt pretensioners can
damage the safety belt system and prevent it
from working cor rectly in a collision.
There are some important things you have to know to make sure that the effectiveness of the
syst em will not be impaired and that discarded
components do not cause injury or pollute the
environment.
_&. WARNING
Improper care, servicing and repair proce­
dures can increase the risk of personal injury
and death by preventing a safety belt preten­
sioner from activating when needed or acti­
vating it unexpectedly :
- The belt pretensioner system can be activat­
ed only once.
If belt pretensioners have
been activated , the system must be re­
placed.
- Never repair, adjust, or change any parts of
the safety belt system.
- Safety belt systems including safety belt
pretensioners cannot be repaired. Special
procedures are required for removal, instal­
lation and disposal of this system.

Other things that can affect Advanced
Airbag performance
Changing the vehicle 's suspension system can
change the way that the Advanced A irbag System
pe rforms in a crash. For example, using t ire-rim
comb inat ions not approved by Audi, lowering the
ve hicl e, chang ing the stiffness of the suspension,
including the spr ings, suspension s truts, shock
absorbers etc . can change the forces that are
measured by the airbag sensors and sent to the
electronic control un it. Some suspension changes
can, for example, increase the force levels meas­
ured by the sensors and make the airbag system
deploy in c rashes in which it wo uld not deploy if
the changes had not been made. Other ki nds of
changes may reduce the force levels measured by
the sensors and preve nt the airbag from deploy­
i n g when i t should .
A WARNING
Changing the vehicle's s uspension including
use of unapproved ti re -rim comb inations can
change Advanced A irbag pe rformance and in ­
crease t he risk of serious persona l injury in a
crash.
- Never install suspension components that do not have the same performance charac­
teristics as the components or iginally insta l­
led on your veh icle.
- Never use tire-rim combinations that have
not been approved by Audi.

A WARNING
Items stored between t he safety be lt b uckle
and the center console can cause the sensors i n the buckle to send the wrong informat ion
to the electronic control module a nd prevent
the Adva nced Airbag System from wor king
properly.
- Always ma ke sure that nothing can interfere

Knee airbags
Description of knee airbags
Applies to vehicles: with knee airbags
The knee airbag system can provide supplemen­
tal protection to properly restrained front seat
occupants.

The knee air bag offers addi tional protec tion to
t h e d river 's and passenge r's knees and uppe r and
l ower thigh areas and supplements the protec ­
tion provided by the safety belts.

Driving and th e environment
Regular maintenance
A badly tuned engine unnecessarily wastes a lot
of fuel .
.,. Have your vehicle serviced at regula r intervals.
By having your vehicle regularly serviced by an
authorized Audi dealer he lps 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
f uel c onsump­
tion .
C he ck you r oil e ach t ime you fill you r ta nk .
The amount of oil used is related to engine load
and speed.
It is normal for the oil consumption of a new en­
g ine to reach its lowes t va lue after a cer tain mile ­
age has been d riven .
You must d rive you r vehicle about 3,000 miles
(5 ,000 k ilometers) before you can properly as­
sess o il cons umption .
This a lso applies to fuel consumption and engine
output.
(D Note
- Have your vehicle maintained properly and
in accordance w ith the service recommenda­
tions in you r Warra nty
& M aintenance book­
l et . Lack of p roper m aintenance as well as
i mprope r use of the vehicle will impair the
funct ion of the emission control system and
could lead to damage.
- Do not a lter or remove any component of
the Emission Cont ro l System unless ap­
proved by the manufacturer.
- Do not a lter o r remove any dev ice, such as
heat shie lds, switches, ignition wires,
va lves, which are designed to protect your
vehicle's Emiss ion Control System and other
i mportant veh icle components.

· Fewer short trips
Fuel consumption will always be relatively high
on short trips .
.,. Try to avoid dr iv ing short distances with a cold
eng ine .
The eng ine and catalytic converter have to reach
their opt imal
oper atin g temperature to reduce
fuel consumpt ion and noxious emissions effec­
tively .
Just after starting, a co ld engine in a mid-s ize car
on ly achieves a fuel economy of 6-8 mi les 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 eng ine is
at its proper operating temperature and fuel
economy has reached a norma l level. So you can
see that you should avo id short trips whenever
poss ible .
The
out side t emp eratur e is also cr itical in th is re­
gard. Your car consumes more fuel in the winter
than in the summer.

Care and cleaning
- Never use gasoline, spot remove r, ben ­
zene, paint thinner or other solvents to
remove .
-Door wind ows
-Remove snow and ice on w indows and ex-
terior mirrors w ith a plastic scraper. To

forming.
Placing your vehicle out
of service
If you wo uld like to take yo ur vehicle out of serv­
ice for a longer time, contact your authorized
Audi dealer or qualified repair facility . They will
advise you of important measures ., such as ..,.

fill up at busy gas stations where the seasonal
adjustment is more likely to be made in time.
(D Note
- Fuels containing a high pe rcentage of etha­
no l such as ESQ and E85 may only be used in
vehicles with f lexible fuel engines. Using
high ethanol fuel in veh icles not equ ipped
with flexible fuel engines can cause severe
engine damage.
- Methanol fuels which do not meet these re­ quirements may cause corrosion and dam­
age to plastic and rubber components in the
fuel system.
- Do not use fuels that fail to meet the spec i­
fied criter ia in this chapter .
- If you are unable to determine whether or
not a particular fuel blend meets the speci­
fications, ask your service station or its fuel
supplier .
- Do not use fuel for wh ich the contents can­
not be identified.
- Fuel system damage and performance prob­
lems resulting from the use of fuels differ­
ent from those spec ified are not the respon­
s ibility of Audi and are not covered under
the New Vehicle o r the Emission Cont ro l
System Warranties.
- If you experience a loss of fue l economy o r
driveability and pe rformance problems due
to the use of one of these f uel b lends, we
r ecommend that yo u switch to unb lended
fuel.
Ethanol fuel (Bio-ethanol)
Applies to vehicles: with flexible fuel engine
You can recognize vehicles with a flexible fuel
engine by looking at the label on the inside of the fuel filler flap.
Vehicles w ith f lexible fuel engines may be operat­
ed with bio-ethanol fuels such as E85 (85% e tha ­
nol and 15% gasoline) or with unleaded gasoline
(91 AKI/ROZ 95) . The vehicle may also be operat­
ed with a m ixt ure of these fuels.
Fu el and R efu elin g
Your f uel consumption wi ll increase when using
bio-ethano l fue ls due to the lower amount of en­
ergy contained per unit vo lume in ethano l.
Warming up the fle xible fuel engine in low
t e mperatu res
Due to the chemical composition of b io-ethanol,
a certain amount of fue l ends up in the engine oil
when driving short distances in
very low temper­
atures. This fuel evaporates again when the en­
gine is warmed up .
II Please w arm up eng ine .
If the driver message appears in the instrument
cluster disp lay, drive with a warm engine to re ­
duce the oil leve l.
(D Note
-Never fill with methano l or with a h igher
percentage of b io-ethanol than 85% (E85).
A highe r percentage of bio-ethanol in the
fue l can cause damage to the engine or to
the fuel system.
- If you use on ly E85, it is recommended to
fill the fue l tank complete ly w ith unleaded
premium grade gasoline every 5,000 miles.
- If you experience starting, rough id le or hes­
itat ion driveab ility problems, fill the fuel
tank complete ly w ith unleaded premium
grade gasoline and drive it normally unt il
the gaso line is used. See your author ized
Audi dea ler if the problem pe rsists.
- Inform your author ized Audi dealer that you
are operating or have operated the vehicle
w ith E85.
- Read and follow the information and t ips
about gasoline<=:>
