On-Board Diagnostic
system (OBD)
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIL) Ill in
the instrument cluster is part of the On-Board
Diagnostic (OBD II) system.
The warning/indicator light illuminates when
the ignition is switched on and goes o ut after
the engine starts and the idle has stabilized.
This indicates that the MIL is working proper­
ly.
If the light does not go out after the engine
is started, or illuminates whi le you are driv­
ing, a ma lfunction may exist in the engine sys­
tem. If the light illuminates, the catalytic con­
verter could be damaged.
Continue driving
with reduced power (avoid­
ing sustained high speeds and/or rapid accel­
erations) and have the condition corrected.
Contact your authorized Audi dealer .
If the light illuminates, the electronic speed limiter may also be malfunctioning. For more
information ¢

Pollutant filt er
The pollutant filter (particle filter) ensures
that contaminants in the outside air (such as
d ust or pollen) are greatly reduced or stop­
ped. The air is also filtered in recircu lation
mode.
The po llutant filter element must be changed
according to the intervals specified in the
maintenance schedule so that the air condi­
tioning system's performance is not adversely
affected .
If the filter's effectiveness is weakened by
driving the vehicle in areas with heavily pollut­
ed outside air, the filter element should also
be changed in between the listed services.
A WARNING
For safety reasons, it is important that all
w indows are free of ice, snow, and conden­
sation. Only then is good visib ility ensured.
Please fam iliari ze yourse lf with the co rrec t
operation of the air conditioning and how
to de humidify/defrost the windows .
([) Note
-If you suspect that the clima te controls
have been damaged, swi tch the system off to avoid damaging it, and have it in­
spected by an authorized Audi dea
ler .
- Audi climate control system repairs re­
quire special expertise and the proper
tools . You should contact an authorized
Audi dealer in the event of malfunctions.
(D Tips
- To avoid adversely affecting heating and
cooling performance and to prevent con­
densation on the windows, the air intake
in front of the windshield must be free of
ice, snow, and leaves.

106 Safety belts
_& WARNING
Improperly worn safety belts increase the
risk of serious personal injury and death
whenever a veh icle is being used .
- Always make sure that all vehicle occu-
pants are cor rect ly restrained and stay in
a correct seating posit ion whenever the
vehicle is be ing used.
- Always read and heed all WARNINGS and
other important informat ion
c::>page 102.
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 safe ty belts are equippe d with safety be lt
pretensioners. The sys tem is activated by sen ­
sors in front and side collisions of great se­
verity. This tightens the belt and takes up belt
slack
c::> .&. in Service and disposal of safety
belt pretensioner on page 106.
Tak ing up the
slack helps to reduce forward occupant move­
ment during a co llision .
(D Tips
The safety be lt pretensioner can only be
activated once.
- In m inor frontal and side coll isions, in
rear-end collisions, in a rollover and in
accidents involving very little impact
fo rce , the safety belt pretens io ner are
not act ivated.
- When the safety be lt pretensioner is ac­
tivated, a fine dust is released . This is
no rma l and is not caused by a fi re in the
vehicle.
- The rel eva nt safety requirements must
be obse rved when t he vehicle or compo­
nen ts of the system are scr ap ped . A
q ualified dea le rship is famili ar wi th
these re gulations and w ill be pleased to
p ass on the informat io n to you. - Be sure to observe all safety, env
iron ­
menta l and other regu lations if the ve hi­
cle or individual parts of the system, par­
ticu larly the safety belt or airbag, are to
be disposed. We recommend you have
your authorized Audi dealer perform this service fo r you.

· Other things that can affect Advanced
Airbag performance
Chang ing the veh icle's suspens io n system can
change the way that the Advanced Airbag Sys­
tem perfo rms in a c rash. For examp le, using
t ir e- rim combinat ions not approved by A udi ,
lower ing the veh icle, c hanging the st iffness of
the suspens ion, including the spr ings, suspen­
sio n struts, shock absorbers etc . can change
the forces that ar e measured by the airbag
sensors and sent to the electronic contro l
unit. Some suspension changes can, for exam­
ple, increase the force levels measured by the
senso rs and make the airbag system deploy in
c rashes in which it wou ld no t deploy if the
c h anges had not been made. Other kinds of
c h anges may reduce the fo rce leve ls meas ­
u red by the sensors and p reven t the airbag
from dep loying when it should.
A WARNING
Changing the vehicle's suspension includ­
i ng use of unapproved tire-rim combina­
tions can change Advanced Airbag per­
fo rmance and increase the r isk of serious
personal injury in a crash .
- Never install suspension components
that do not have the same performance characterist ics as the components origi ­
na lly installed on your vehicle .
- Never use tire-rim combinations that
have no t been approved by Audi.

the exhaust system and this could cause
the catalytic converter to overheat.
- Do not turn off the ignition while the ve ­
hicle is moving .
- Do not continue to operate yo ur vehicle
under these conditions, as otherwise fuel
can reach the cata lytic converter. This
could result in overheating of the con­
verter, requ iring its replacement.
- 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 Warranty
&
Ma intenan ce booklet.
- Lac k of proper maintenance as well as
improper use of the vehicle will impa ir
t he funct ion of the emission control
system and cou ld lead to damage.
@ For the sake of the environment
Even when the Emission Contro l System is
operating p roperly, the exhaust gas can
have a s ulfu r- like exhaust gas smell under
some operating states. This depends on
the s ulfur content of the fue l being used.
Using a different brand of fuel may help,
or filling the tank w ith lead-free super
grade gasoline .
Shutting down vehicle
If you would like your veh icle to remain inop­
erat ive for a longer period of time, contact an
Aud i or other specialized deale r. T hey can ad­
vise you on necessary precautions e.g . corro­
sion prevention, ma intenance and storage.

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, environmenta l impact, and
wear on your eng ine, brakes and tires largely
depend on three factors:
- your personal d riving s tyle
- operati ng conditions
- technical limitat ions
If you ant ic ipate what you need to do next and
drive economically, you can easily cut you r
fuel consumpt io n by 1O-lS percent . T his sec­
tion w ill give you some tips on how you can
help the env ironment and your po cketbook.
@ Tips
The consumption estimates as published
by ENVIRONME NTAL PROT ECTI ON AGENCY
( E PA) a nd Tra nsp o rt Canada may no t corre­
spond to your actual consump tion on the
r oad, which will va ry depending upon vehi ­
cle load and speed, road and weather con­
ditions, trip length, etc.
Drive smoothly and keep a lookout
ahead
Vehicles use the most fuel when they are ac­
celerating.
Avoid unnecessary acce lerating and braking .
Vehicles use the most f ue l when they are ac­
ce le rat ing. If you ant icipate what is going to
happen next, you will need to brake less and,
thus, acce lerate less . Let the vehicle coast
whenever possible - for examp le when you see
that the next traff ic light is red.
