Dr iv ing and e n v ir onm e nt
- Be aware that just one tank fi lling with
leaded fuel will already seriously de-
grade the performance of the catalytic
converter.
- Do not exceed the correct engine oil leve l
¢ page 226.
- Do not drive until the fuel tank becomes
completely empty. The eng ine could mis-
fire. Unburned fuel could also get into
the exhaust system and this could cause
t he catalyt ic converter to overheat.
- Do not switch off the ign ition wh ile the
vehicle is moving.
- Do not continue to operate your vehicle
under these conditions, as otherw ise fuel
can reach the catalytic converter. This
could result in overheat ing of the con-
verter, req uiring its repla ceme nt.
- To assure efficient operation of the Emis-
s ion Control System:
- Have your vehicle maintained properly
and in accordance with the service rec-
ommendations
in your Warranty &
Maintenance 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 cou ld lead to damage.

For the sake of the environment
Even when the Emission Contro l System is
operating properly, the exhaust gas can
have a sulfur-like exhaust gas smell under
some operating states. This depends on
t he sulfur content of the fue l being used .
Using a differe nt brand of fuel may help,
or filling t he tank wit h lead-free super
grade gaso line .
