(D Note
-Be aware that just one tank fi lling with
le ad ed fuel will already seriously de­
grade the performance of the catalytic
converter.
- Do not exceed the correct engine oil leve l
c>page 199.
-Do not drive until the fuel tank becomes
complete ly empty. The engine could mis ­
fire. Unburned fuel could also get into
the exhaust system and this could cause
the catalyt ic converter to overheat.
- Do not turn off the ignition while the ve­
hicle is moving .
- Do not continue to operate your vehicle
under these condit ions, as otherwise fuel
can reach the catalytic converter. This
could result in overheat ing of the con­
verter, requ iring its replacement.
- To assure efficient operat ion of the Emis­
s ion Control System:
- Have your vehicle maintained properly
and in accordance with the service rec­
ommendations in your Warranty
&
Ma intenance booklet.
- Lack of proper maintenance as well as
improper use of the vehicle will impa ir
the funct ion of the emission control
system and could lead to damage .
@) For the sake of the environment
Even when the Emission Control System is
operating properly, the exhaust gas can
have a sulfur-like exhaust gas smell under
some operating states. This depends on
the s ulfur content of the fuel being used.
Using a d ifferent 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
Audi or other specialized dealer. They can ad­
vise you on necessary precautions e .g. corro ­
sion prevention, maintenance 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 d riving style
- operating 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 10-15 percent . This sec­
tion w ill give you some tips on how you can
help the env ironment and your pocketbook.
(D Tips
The consumption estimates as published
by ENVIRONMENTAL PROTEC TION AGENCY
( E PA) and Transpo rt Canada may not cor re­
spond to your actual consump tion 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 accelerating and braking.
Vehicles use the most f uel when they a re ac­
ce lerat ing. If you ant icipate what is going to
happe n next, you will need to brake less and,
th us, acce lerate less . Let the vehicle coast
whenever possible -for examp le when you see
that the next traff ic light is red.

208 Check ing and filling
- To r educe the danger of explosion, never
co nnect or disconn ect cha rger cables
wh ile the c harger is operating.
- Fast char ging a battery is dangerous and
shou ld on ly be attempted by a compe­
tent technician w ith the proper equip­
ment .
- Battery acid that may spill during charg­
ing should be washed
off with a solution
of warm water and baking soda to neu ­
tralize the acid.
(Q) Note
Never use a fast charger as a booster to
start the engine . This will seriously dam­
age sensitive electronic components, such
as control units, relays, rad io, etc., as we ll
as the battery charger.
Battery replacement
The new battery must have the same specif/·
cations and dimensions as the original equip­
ment battery.
Intell igent energy management in your veh i­
cle is respons ible for d istributing the e lectr i­
cal energy throughout you r vehicle
q page 177. The intell igen t energy m anage­
men t system w ill keep the engine ba tte ry
charged better then vehicles w ithout this sys­
tem . To make sure the additional e lectrica l en­
ergy is available once again after you have
changed the battery, we recommend that you install batteries o f the same type and ma nu­
facture only (the same as those installed at
the time your vehicle was delivered). Specifi­
cations are listed on the battery hous ing. Your
author ized Audi dealer must code the battery
in the ene rgy management system to enable
you to use the energy management functions
correctly after replac ing the battery.
I f it is not poss ible to use a battery of this
type, the new bat tery m ust h ave the s ame ca­
pac ity, voltage ( 12-volts), amperage, con ­
struction and plug sea ling. When installing the battery, make su
re the ig ­
nition and a ll electrical consumers are turned
off.
(D Note
Make sure the ventilation hose on the side
of the battery is connected, otherwise
fumes or battery acid can leak out .
@ For the sake of the environment
Because o f the p rob lem of p roper disposal
of a battery, we recommend your author ­
i zed Audi dealer change the battery for
you. Batteries contain sulfur ic acid and
l ead and must always be disposed of prop­
erly in comp liance with all environmental
regulations. Dispos ing of vehicle batter ies
i mprope rly is very dange rous to the envi­
r o nment .
