Checking and Filling
"'Never put too much motor oil in your engine
¢ page 193 , Checking the engin e oil lev el and
adding oil.
"'Never try to push- or tow-star t your vehicle.
The catalytic converter is an efficient "clean-up"
device built into the exhaust system of the v ehi­
cle. The catalytic 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
portant for the life of the catalytic converter 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 exhaust 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 mani­
fold, exhaust pipes, catalytic converter or heat shields. During driving, the substance
used for undercoating could overheat and
cause a fire.
(D Note
- Be aware that just one tank filling with
leaded fuel will already seriously degrade
the performance of the catalytic converter.
- Do not exceed the correct engine oil level
¢page 193.
-Do not drive until the fuel tank becomes
completely empty. The engine could mis­
fire. Unburned fuel could also get into the
exhaust system and this could cause the
catalytic converter to overheat.
- Do not switch off the ignition while the vehi­
cle is moving.
- Do not continue to operate your vehicle un­
der these conditions, as otherwise fuel can reach the catalytic converter. This could re-
188
sult in overheating of the converter, requir­
ing its replacement.
- To assure efficient operation of the Emis­
sion Control System:
- Have your vehicle maintained properly and
in accordance with the service recommen­
dations in your Warranty
& Maintenance
booklet.
- Lack of proper maintenance as well 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 Emission Control System is op­
erating properly, the exhaust gas can have a
sulfur-like exhaust gas smell under some op­
erating states. This depends on the sulfur
content of the fuel being used. Using a differ­
ent brand of fuel may help, or filling the tank
with lead-free super grade gasoline.

Cooling system
Coolant
The engine coo ling system is filled wi th a mixture
of purified water and coolant additive at the fac ­
tory. This coo lant must not be not changed.
The coolant leve l is moni to red throug h the . in ­
d icator light

mend occasiona lly checking the coo lant level
manually.
If you m ust add coo lant, use a m ix ture of water
an d coolant addit ive. Mixing the coolant additive
with d isti lled water is recommended.
Coolant additive
The coolan t additive is made of anti-freezing and
corros ion pro tection agents. Only use the fol low­
in g coolant add it ives. The se addi tives may be
mixed wit h each other.
