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 vehicle to dr ive
through safely.
-
Avoid driving through sa lt 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
.
~
Always use lead-free gasoline

Fuel supply
.
~
Never run the tank down a
ll
the way to empty
.
~
Never put too much motor oil in your engine

Never t
ry to push- or tow -start your veh icle.
The cata lytic conve rter is an eff icient "clean-up"
dev ice bu ilt into the exhaust system of
t
he vehi-
cle. The cataly
ti
c converter burns many of the
pollutants in the exhaust gas before they are
re-
leased into the atmosphere.
The exclusive use of unleaded fuel is critically im-
por
t
ant for the life of the catalyt ic converte
r
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
operate the vehicle in areas
whe re the hot exhaust system may come in
contact with dry grass, brush, fue
l
spill or
other mater ial which can cause a fire.
-
Do not apply additional undercoating or
rustproofing on or near the exha ust man i-
178
fold, exha ust pipes, catalytic converter 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 fill ing with
lead·
ed
fue
l will
already ser iously degrade the
performance of the catalytic converter.
-
Do not exceed the correct engine oil level
c:::;,page
199.
-
Do not drive until the fue
l
tank becomes
completely empty. The engine could m isfire.
Unburned fuel could also get into the ex-
haust system and this could cause the cata-
lyt ic converter to overheat.
-
Do not turn off the ignition while the vehicle
is moving
.
-
Do not continue to operate your veh icle un-
der these conditions, as otherwise fuel can
reach the catalytic converter
.
This could re-
sult in overheating of
t
he conve rter, requ ir-
ing its replacement.
-
To assure efficient operation of the Emission
Cont ro
l
System:
-
Have your vehicle maintained properly and
in
accordance with the se rvice recommen-
dations in your Warranty & Maintenance
booklet.
-
Lack of proper maintenance as we
ll
as im-
proper use of the vehicle will impair 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-
e rat ing proper ly, the exhaust gas can have a
sulfur-like exhaust gas sme
ll
under some op-
erat ing states. This depends on the sulfur
content of the fuel being used. Using a d iffe r-
ent brand of fue
l
may he lp, or fi lling the
t
ank
wit
h lead-free super grade gaso line.
Shutting
down
vehicle
If you would like you
r
vehicle to remai
n
inope ra-
tive for a longer period of time, con
t
act an Audi
o
r
other spec ia lized dealer. They can adv ise you
