CD Note
- Vehicle components such as the engine,
transmission, suspension or electrical sys-
tem can be severely damaged by driving
through water.
- Always switch the Start-Stop-System* off
when driving through water
9 page 79.
@ Tips
- Determine the depth before driving through
water.
- Do not stop the vehicle, 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 drive
through safely.
-Avoid driving through salt water (corrosion).
Catalytic converter
Applies to vehicles: with gasoline engine
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 9 page 208,
Fuel supply.
... Never run the tank down all the way to empty.
.,. Never put too much motor oil in your engine
9 page 220, Adding engine oil~-
.,. Never try to push- or tow-start your vehicle.
The catalytic converter is an efficient "clean-up"
device built into the exhaust system of the vehi-
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.
Driving and the environment
- 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.
CD 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
9page220.
- 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-
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
