Tips
-
Check the depth of the water before driving
through it
.
-
Do not stop 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 veh icle to drive
through safely.
-
Avoid driving through salt water because it
can cause corrosion.
Catalytic
converter
It is very
important that
your emission control
system (catalytic converter) is functioning prop-
erly to ensure that your vehicle is running in an
environmentally sound manner
.

The cata lytic converter is an efficient "clean-up"
dev ice bu ilt into the exha ust system of
t
he vehi-
cle. The cata lytic conve rter burns many of the
pollutants in
t
he exhaust gas before they are re
-
leased into the atmosphere.
The exclusive use of unleaded fue
l
is critica lly im-
portant for the life of
t
he catalytic conve rter and
proper functioning of the engine.
A
WARNING
,..____
-
-
The temperature
of the exhaust system is
high, both when driving and after stopping
the engine.
-
Never touch the exha ust tail pipes once they
have become hot.
This
could result in burns.
-
Do not park or ope rate t he vehicle in areas
where the hot exha ust system may come in
contact with dry grass, br ush, fue
l
spill or
other mater ial which can cause a fire.
-
Do not apply additional undercoating or
rustproofing on or near the exhaust mani-
178
fold, exha ust pipes, cata lytic conve rter or
heat shields. During driving, the substance
used for undercoat ing could overheat and
cause a f ire.
Cl)
Note
-
Be aware that just one tank f illing wit
h
leaded
f ue
l will
already seriously degrade
the performance of the catalytic converter.
-
Do not exceed the correct engine oil leve
l
¢page
195.
-
Do not drive until the fue
l
tank becomes
completely empty. The engine could mis-
fire. Unbu rned fue
l
cou ld also get into the
exhaust system and this could cause the
catalytic converter to overheat.
-
Do not turn off the ign ition while the vehicle
is moving
.
-
Do not continue to operate your vehicle un-
der these conditions, as otherw ise fuel can
reac
h
the catalytic converter. This could re-
sult in overheat ing of
t
he converter, requir-
ing its replacement.
-
To assure eff icient operat ion of the Emis-
sion Contro
l
System:
-
Have you
r
vehicle maintained properly and
in
accordance wit
h
the service recommen-
dations in your Warranty & Maintenance
booklet.
-
Lack of proper ma intenance as well as im-
proper use of the veh icle will impa ir the
function of the emission control system
and could lead to damage.
(®
For the sake of the environment
Even when the Emiss ion Control System is op-
erating properly, t he exhaust gas can have a
sulfur-like exhaust gas smell under some op-
erating states. This depends on the sulfur
content of
t
he fuel being used. Using a d iffer-
ent brand of fuel may help, or filling the tank
wit
h lead-free super g rade gasoline.
Shutting
down
vehicle
If you wo uld like
your
vehicle to remain inopera-
tive for a longer pe riod of time, con
t
act an Audi
o
r
other spec ia lized dealer. They can adv ise you
