On-Board Diagnostic
system (OBD)
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (M IL) Iii in
the instrument cluster is part of the On-Board
Diagnostic (OBD
II) system.
The warning/indicator ligh t illuminates whe n
the ignition is switched on and goes out after
the eng ine starts and the idle has stabilized.
This indicates that the MIL is working proper­
ly .
If the light does not go out after t he engine
is started, or illuminates while you are driv­
i ng, a malfunction may exist in the eng ine sys­
tem. If the light illuminates, the catalytic con­
verter could be damaged .
Contin ue driving
with reduced power (avoid­
i ng sustained high speeds and/or rapid accel­
erations) and have the cond ition corrected.
Contact your a uthorized Audi dea ler.
If the light il luminates, the electronic speed
limiter may also be malfunct ioning. For more
information

Using the climate controls economically
Economical use of the climate controls helps
to save fuel .
When climate control is working in coo ling
mode, engine performance is reduced and
fuel consumption is affected . To keep the time the air cond
itioning is on as short as possible,
you should do the following:
.,. If you would like to save fuel, switch the air
conditioning off .
.,. If you open the windows while driving,
switch the air conditioning off .
.,. If the veh icle is extreme ly hot due to the
heat of the sun, br iefly open doors and w in­
dows .
@ For the sake of the environment
When yo u save fuel, you reduce emissions
from the vehicle.

Speed warning system
Overview
The speed warning system helps you to keep
your driving speed below a set speed limit.
The speed warn ing system warns the driver if
he exceeds a previous ly stored max imum
speed . A warning tone will sound as soon as
the ve hicle speed exceeds the set speed by
about 3 mph (3 km/h). At the same time, a
warning symbo l appea rs in the display.
The speed warn ing system has
two warning
thr esho lds
that f unction independently of
each other and that have somewhat different
purposes:
Speed warning 1
You can use speed warning 1 to set the maxi­ mum speed while you are driving . This setting
will remain in effect unti l yo u tur n off the ..,.

Avoid damaging the
vehicle
When you are driving on poor roads, or over
curbs, steep ramps, etc., make certain that
low-lying parts such as spoilers and exhaust
system parts do not bottom out and get dam­
aged.
T his is especially true for vehicles with low­
slung chassis (sports chassis) and fully loaded
vehicles .
Driving through water
on roads
Note the following to avoid vehicle damage
when driving through water, for example on
flooded roads:
- T he water must not be any higher than the
bottom of the veh icle body.
- Do not d rive faster than wa lking speed.
..&, WARNING
After driving through wate r, m ud, slush,
etc., the brakes may be slow to take effect
because of wet brake rotors and pads . Dry
the brakes first by braking carefully to re­
store the full braking effect.
(D Note
Vehicle components such as the engine,
transmiss ion, suspension or electrical sys ­
tem can be severely damaged by driving
through water.
- Check the depth of the water before driv ­
ing through it.
- Do not s top the veh icle, drive in reverse
or switch the engine off when driving
through water.
- Keep in mind that oncoming vehicles may create waves that raise the water
level and make it too deep for your vehi­
cle to drive through safely.
- Avoid driving thro ugh sa lt water because
it can cause corrosion.

Catalytic converter
It is very important that your emission con­
trol system (catalytic converter) is function­
ing properly to ensure that your vehicle is run­
ning in an environmentally sound manner .
.,. Always use lead-free gasoline¢ page 161 ,
Fuel supply.
.,. Never run the tank down all the way to emp­
ty.
.,. Never put too much motor o il in your engine
c:::> page 170, Adding engine oil 9::71 .
.,. Never try to push- or tow-sta rt you r vehicle.
The catalytic converter is an efficient "clean­
up" dev ice built into the exhaust system of
the vehicle. The cata lytic conve rter bu rns
many of the pollutants in the exha ust gas be­
f ore they are re leased into the atmosphere .
T he exclusive use of unleaded fuel is critically
important for the life of the catalyt ic convert­
er and prope r fu nct ion ing of the engine .
A WARNING
-
- Do not park or operate the vehicle in
areas where the hot exha ust system may
come in contact with dry grass, brush,
fue l spill or other materia l wh ich can
cause a fire .
- Do not apply additional undercoating or
rustproof ing on or near the exhaust
manifold, exhaust pipes, catalytic con­
verter or heat shields. Dur ing driving, the
substance used for undercoating could
overheat and cause a fire .
(I) Note
-Be aware that just one tank filling with
leaded fuel w ill already ser iously de­
grade the performance of the catalytic
converte r.
- Do not exceed the correct eng ine oil level
c:::> page 170.
- Do not drive until the fue l tank becomes
completely empty . The engine could m is-
fire. Unburned fuel could also get into

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 otherw ise 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 intained properly
and in acco rdance with the service rec­
ommendations in your Wa rranty
&
Ma intenance booklet.
- La ck of proper main tenance 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
E ven when the Emission Contro l System is
operating p roperly, the exhaust gas can
have a s ulfur -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,
or filling the tank w it h lead-free super
grade gasoline.
Shutting down vehicle
If you wou ld like your veh icle to remain inop­
erat ive for a longer period of time, contact an
Aud i or other specialized dealer . T hey ca n ad­
vise you on necessary precautions e.g . corro­
sion prevent ion, 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 engine, brakes and tires largely
depend on three factors:
- your personal driving style
- oper ating conditions
- technical limitat ions
If you ant ic ipate what you need to do next and
drive economically, you can easily cut your
fuel consumpt ion by 1O-lS percent . This sec­
t ion w ill give you some tips on how you can
help the env ironment and your pocketbook.
@ Tips
The consumption estimates as published
by ENVIRONME NTAL PROTEC TION AG ENCY
( EP A) and Transpo rt Canada may no t corre­
spond to your actual consumption 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 ore ac­
celerating.
Avoid unnecessary acce lerating and braking .
Vehicles use the mos t fu el when they are ac­
ce le rat ing. If yo u ant icipate what is going to
happen next, you will need to brake less and,
t hu s, acce le rate less . Let the vehicle coast
whenever possible -for examp le when you see
that the next traff 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.
Accelerating gently reduces fuel consump­
tion, engine wear, and does not disturb the
environment.
Fu el consumption, exhaust emissions and en ­
g ine noise increase disproportionately at high
speeds. If you drive at approximately three
quarters of top speed, fuel consumption will
be reduced by one half. Never drive faster
than the posted speed limit and weather con­
ditions permit .
Reducing unnecessary idling
Even when your car is just idling it burns up
fuel.
""Shut the engine off when you are not driving
the vehicle.
""Do not warm up the vehicle by letting the
engine run at idle .
It makes sense to shut
off the engine in traff ic
jams, when waiting for trains to pass at ra il­
road crossings, or at traffic lights that have
l ong wa its on red. Turning the engine
off for
just
30-40 seconds saves more fue l than is
burned starting the engine again .
It takes a long time for the engine to warm up
fully when it is running at idle. However, wear
and noxious emissions 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 improper operation, they
would go unheeded. Extended idling also
produces heat, which could result in over-
Driving and environment 153
'
heating or othe r damage to the vehicle or
other property.
Regular maintenance
A badly tuned engine unnecessarily wastes a
lot of fuel.
""H ave your veh icle serviced at regular inter-
vals.
By having your vehicle regu larly serviced by an
Audi dealer helps to ensu re that it runs prop­
erly and economically. The condition of your
vehicle not only affects its safety and ability to
hold its value, it also affects
fuel consump­
tion.
Check your oil each time you fill your tank.
The amount of o il used is related to engine
load and speed.
It is normal for the oil consumption of a new
engine to reach its lowest value after a certain
mileage has been driven.
You must drive your vehicle about 3,000 miles
(5,000 kilometres) before you can properly
assess oil consumpt ion.
This also app lies to fue l consumption and en­
gine output.
(U) Note
- Have your vehicle maintained properly
and in accordance with the service rec­
ommendations in your Warranty
& Main­
tenance booklet. Lack of proper mainte­
nance as well as improper use of the ve­
hicle will impair the function of the
emission control system and could 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 shields, switches, ignition wires,
valves, which are designed to protect
your vehicle's Emission Control System
and other important vehicle compo­
nents .

154 Driving and environment
Fewer short trips
Fuel consumption will always be relatively
high on short trips .
.,. Try to avo id driving short distances with a
cold eng ine.
The engine and catalyt ic converte r have to
reac h their optimal
operating temperature to
reduce fuel consumption and noxious emis­
sions effect ively .
- Just after starting, a co ld engine in a m id­
s iz e car burns the fuel at a poor rate of 6-8
miles per gallon (30-40 l/l00km). Half a
mile dow n the road, the m ileage imp roves
to 12 M PG (20 l/100 km) . It will take t he
engi ne no less than
two and a half mil es
(4 km) of driving to warm up to its prope r
oper ating tempe ra tur e and ope rate at an
e conomi c mileage. This explains w hy taking
t h e car for s hort tr ips is a rat her wastef ul
co nvenience.
- T he
outside temperature is also cr itica l in
t h is regard. Yo ur car consumes more fuel in
t h e winter than in t he summer .
