Catalytic
converter
Applies to vehicles: with gasoline engine
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

.,. Never try to push- or tow-start your veh icle.
The catalytic converter is an eff icient "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.
The exclus ive use of unleaded fuel is crit ically
important for the life of the cata lytic convert-
e r and proper functioning of the engine.

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 where the hot exhaust system may
come in contact with dry grass, brush,
fuel spill or other material which can
cause a fire.
- Do not apply additional undercoating or
rustproofing on or near the exhaust
manifold, exhaust pipes, catalytic con-
verter or heat shields . During driving, the
substance used for undercoating cou ld
overheat and cause a fire.
(D
Note
- Be aware that just one tank f illing with
leaded fuel will already seriously de-
grade the performance of the catalytic
conve rter.

- Do not exceed the correct engine oil level
c::>
page 261.
- Do not drive until the fue l tank becomes
completely empty. The engine cou ld mis-
fire. Unburned fuel could also get into
the exhaust system and this cou ld cause
the catalytic converter to overheat.
- Do not turn off the ignition while the ve-
hicle is mov ing.
- Do not continue to operate your veh icle
under these conditions, as otherwise fuel
can reach the catalyt ic converter. This
cou ld result in overheating of the con-
verter, requir ing its replacement.
- To assure efficient operation of the Emis-
sion Control System:
- Have you r vehicle main t ained properly
and in accordance w ith t he se rvice rec-
ommendations
in your Warranty &
Maintenance book let.
- Lack of proper maintenance as we ll as
improper use of t he vehicle will impair
the function of the emission contro l
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 operat ing states. This depends on
the sulfur content of the fuel being used .
Using a different brand of fuel may help,
or filling the tank with lead-free s uper
g rade gasoline.
Diesel
particulate
filter
Appli es to vehicles: wit h diesel engine
The diesel part iculate filter filters nearly all of
the soot pa rticles out of the exhaust . The fil-
te r clea ns itself automat ically under no rma l
driving cond itions. If the filter cannot clean it -
self (for example, because you are on ly driving
short distances), the filter becomes clogged
with soot and the

symbol for the diese l
particulate filter illuminates
