A WARNING ,~ ~
After driving through water, mud, 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 brak ing effect.
([) Note
Vehicle components such as the engine,
transmiss ion, suspension or electrical sys­
tem can be severely damaged by driving
through wate r.
@ Tips
- Check the depth of the water before dr iv­
i ng through it.
- Do not stop the veh icle, dr ive in reverse
or switch the engine off when driving
th rough water.
- Keep in mind that oncoming vehicles
may create waves that raise the water
level and make it too deep for you r vehi­
cle to drive th rough safely.
- Avoid dr iving through sa lt water because
i t can ca use 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.
11-Always use lead-free gasoline q page 210,
Fuel supply .
"'" Never run the tank down a ll the way to
empty.
11-Never put too much motor oil in your en-
gine
q page 220, ~ Adding engine oil .
11-Never try to push -or tow-start your veh icle .
The catalytic converter is an efficient "clean­ up" device built into the exhaust system of
the vehicle . The catalytic converter burns
many of the pollutants in the exhaust gas be­
fore they are released into the atmosphere .
Drivin g and en vironm ent 193
The exclusive use of unleaded fuel is critically
important for the life of the catalytic convert­
er and proper funct ion ing of the engine.
A WARNING
-
- Do not park or operate the vehicle in
areas where the hot exhaust system may
come in contact with dry grass, brush,
fuel spill or other mate rial wh ich can
cause a fir e.
- Do not apply additional undercoating or rustp roof ing on or near the exhaust
manifold, exhaust pipes, catalytic con­
ve rter or heat shields. During driv ing, the
substance used for undercoating co uld
overheat and cause a fire.
(D Note
- Be aware that just one tank filling with
leaded fu el w il l already ser iously de­
gra de the performance of the catalytic
c onverte r.
- Do not ex ceed t he cor rect eng ine oil level
qpage 220.
- Do not drive until the fue l tank becomes
comple tely empty. The engine co uld m is­
fire . Unburned fuel could also get in to
the exhaust system and th is co uld cause
the catalytic converter to overheat .
- Do not turn off the ignition while the ve ­
hicle is moving.
- Do not continue to ope rate your veh icle
unde r these conditions, as otherwise fuel
can reach the catalytic converte r. T his
cou ld result in overheating of the con­
verter, requir ing its replacement.
- To assure efficient operation of the Emis ­
sion Control System:
- H ave you r vehicle maintained prope rly
and in accorda nce w ith the serv ice rec­
ommendat ions in yo ur Warranty &
M ain tenance boo klet.
- L ack of prope r maintenance as we ll as
improper use of the vehi cle w ill impair
the function of the em ission contro l
system and could lead to damage . ..,. •

212 Fuel supply and filling your fuel tank
Detergent Gasoline, please go to the official
websit e (www.toptiergas .com) .
After an extended period of using inadequate
fuels, built -up carbon deposits can rob your
engine of peak performance.
CD Note
Damage or malfunction due to poor fuel
quality is not covered by the Audi New Ve­
hicle Limited Warranty.
Fuel tank
Fuel filler neck
The fuel filler neck is located on the right rear
side panel behind the fuel fi ller flap.
If the power locking system should fail, you
can st ill open the flap manually -for detailed
instructions see¢
page 214 .
You can find the fuel t ank ca pa city of your ve­
hicle in
Technical Data¢ page 270.
The label on the inside of the fuel filler flap
tells you the correct fuel for your veh icle. For
more inform ation about fuel specifications,
see
¢page 210 .
Your vehicle fuel tank has an on-board refuel­
ling vapor recovery system . This feature helps
to preven t fuel vapors from escaping from the
ta nk and polluting the environment while you
refuel your vehicle . In order to fill the tank
properly while protect ing the env ironment,
p lease follow this refueling procedure careful­
l y .
& WARNING
Under normal operating conditions, never
carry add itiona l fuel containers in your car .
Gas canisters and other containers used to
transport fuel can be dangerous. Such con­
tainers, full or empty, may leak and could
cause a f ire in a collision. If you must
transport fuel to use for your lawn mower,
snow blower, etc ., be very careful and al ­
ways observe local and state laws regard­
ing the use, transportation and storage of such
fuel containers . Make certain the con­
tainer meets industry standards (ANSI/
ASTM F852 -86).
CD Note
Never drive your vehicle until the fue l tank
is completely empty. The irregular supply
of fue l can cause misfir ing. Gasoline could
enter the exhaust system and damage the
catalytic converter .
