& WARNING
Improperly worn safety belts increase the
risk of serious personal injury and death
whenever a vehicle is being used.
- Always make sure that all vehicle occu­
pants are correctly restrained and stay in
a correct seating position whenever the
vehicle is being used.
- Always read and heed all WARNINGS and
other important information
Q page 109.
Safety belt preten­
sioners
How safety belt pretensioners work
In front and side collisions above a particular
severity, safety belts in use are tensioned au­
tomatically.
The safety belts are equipped with safety belt
pretensioners. The system is activated by sen­
sors in front and side collisions of great se­
verity. This tightens the belt and takes up belt
slack
Q &. in Service and disposal of safety
belt preten sioner on page 113.
Taking up the
slack helps to reduce forward occupant move­
ment during a collision .
@ Tips
The safety belt pretensioner can only be
activated once.
- In minor frontal and side collisions, in
rear-end collisions, in a rollover and in
accidents involving very little impact
force, the safety belt pretensioner are not activated.
- When the safety belt pretensioner is ac ­
tivated, a fine dust is released . This is
normal and is not caused by a fire in the
vehicle.
- The relevant safety requirements must
be observed when the vehicle or compo­
nents of the system are scrapped. A
qualified dealership is familiar with
these regulations and will be pleased to
pass on the information to you.
Safety belts 113
-Be sure to observe all safety, environ­
mental and other regulations if the vehi­
cle or individual parts of the system, par­
ticularly the safety belt or airbag, are to be disposed. We recommend you have
your authorized Audi dealer perform this service for you.
Service and disposal of safety belt
pretensioner
The safety belt pretensioners are parts of the
safety belts on your Audi. Installing, remov­
ing, servicing or repairing of belt pretension­
ers can damage the safety belt system and
prevent it from working cor rectly in a colli­
sion.
There are some important things you have to know to make sure that the effectiveness of
the system will not be impaired and tha t dis­
carded componen ts do no t cause injury or pol­
lute the environment .
& WARNING
Improper care, servicing and repair proce­
dures can increase the risk of personal in­
jury and death by preventing a safety belt
pretensioner from activating when needed
or activating it unexpectedly :
- The belt pretensioner system can be acti­
vated only once. If belt pretensioners
have been activated, the system must be
replaced.
- Never repair, adjust, or change any parts
of the safety belt system .
- Safety belt systems including safety belt
pretensioners cannot be repaired. Spe­
cial procedures are required for removal,
installation and disposal of this system.
- For any work on the safety belt system,
we strongly recommend that you see
your authorized Audi dealer or qualified
technician who has an Audi approved re­ pair manual, training and special equip­
ment 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

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 air­

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

-For safety reasons in severe accidents,
the alternator and starter are separated
from the vehicle battery with a pyrotech­ nic 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.
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 measu red 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. ..,.

- To assure efficient operation of the Emis­
sion Control System:
- Have your veh icle ma inta ined properly
and in acco rdance with the service rec­
ommendations in your Wa rranty

@ For the sake of the environment
Even when the Emission Contro l System is
operating p roperly, t he exhaus t gas can
have a s ulfu r- like exhaust gas smell under
some operating states. This depends on
the s ulfur content o f the fue l being used.
Using a different brand of fuel may help,

Operate your vehicle
economically and
minimize pollution
General
Your personal style of driving will determine
the economy of your vehicle, as well as ex­
haust and noise levels .
Fuel economy, environmental impact, and
wear on your engine, brakes and t ires largely
depend on three factors :
- your persona l driving style
- operating conditions
- technical lim itations
I f you anticipate w hat you need to do nex t and
d rive economically, you can eas ily cut your
Dri vin g and en vironm ent 159
fuel consumption by 10 -15 percent. This sec ­
tion w ill give yo u some tips on how you can
help the env ironment and your pocketbook .
(D Tips
The cons umption estimates as publishe d
by ENVIRONME NTAL PROTEC TION AGENCY
(EPA) and Transport Canada may not corre­
spond to your actual consumption on the road, which will vary depending upon vehi­
cle load and speed, road and weather con­
dit ions, trip length, etc.
Drive smoothly and keep a lookout
ahead
Vehicles use the most fuel when they are ac­
celerating.
Avoid unnecessary accelerat ing and braking .
Vehicles use the most fuel when they are ac­
ce lerat ing . If you anticipate what is going to
happe n next, you will need to brake less and,
th us, accele rate less . Let the vehicle coast
whenever possible -for examp le when you see
that the next t raff ic light is red.
Avoid full throttle
Driving at moderate speeds saves fuel and
improves your mileage.
"' Try and keep well below your car's maximum
speed.
Acce lerat ing gently reduces fue l consump­
tion, eng ine wear, and does not disturb the
environment.
Fuel consumpt ion, exhaust emiss ions and en­
gine noise increase disproportionately at high
speeds. If you drive at app roximately three
quarte rs of top speed, fuel consumption w ill
be reduced by one half. Nev er drive faster
t h an the posted speed limit and weathe r con­
ditions perm it.

160 Driving and en vi ro nment
Reducing unnecessary idling
Even when your car is just idling it burns up
fuel .
.,. Shut the engine off when you are not dr iving
the vehicle.
.,. Do not warm up the vehicle by letting the
engine run at idle .
It makes sense to shut
off the engine in traffic
jams, when waiting for trains to pass at ra il­
road crossings, or at traff ic l ights that have
l ong wa its on red . Turning the engine
off fo r
just 30-40 seconds saves more fue l than is
burned starting the eng ine again .
It takes a long time for the engine to warm up
fu lly when it is running at idle . However , wear
and nox ious em issions are especially high
when the engine is warming up. So you should
drive away as soon as you start the engine and
avoid running at high RPMs whi le the engine
is sti ll warming up.
(D Note
Do not leave engine idling unattended af­
ter starting . If warning lights should come
on to indicate imp roper operation, they
wou ld go unheeded. Extended idling also
produces heat, which cou ld 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 serv iced at regular inter-
vals.
By having your vehicle regularly serviced by an
Audi dea ler helps to ensure that it runs prop­
erly and economica lly. The cond it ion of yo ur
vehicle not only affects its safety and ability to
hold its value, it also affects fuel consump­
tion .
Check you r oil ea ch time you fill you r tank. T
he amount o f oi l used is re lated to engine
load and speed.
It i s normal fo r the oil consump tion of a new
engine to reach its lowest value after a certa in
mileage has been d riven.
You must drive your veh icle about 3,000 m iles
(S,000 kilometres) before yo u can properly
assess oil consumpt ion.
T his also app lies to fue l consumption and en­
gine o utput.
(D Note
- Have your veh icle ma inta ined properly
and in acco rdance with the service rec­
ommendations in your Wa rranty
& Main­
t enance boo klet . Lack of p roper ma inte­
nance as well as improper use of the ve­
hicle will impair the function of the
emission contro l system and cou ld 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 sh ie lds, switches, ign it ion w ires,
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 driv ing short distances w ith a
cold engine .
T he engine and cata lytic converter have to
reach their opt imal operat ing temperature to
reduce fuel consumption and nox ious emis­
s ions effectively .
- Ju st after starting, a cold engine in a mid­
size car burns the fue l at a poor rate of 6-8
m iles per gallon (30-40 l/l00km). Half a
m ile down the road , the mileage improves
to 12 MPG (20 l/100 km). It w ill take the
