Crankcase ventilation
The crankcase ventilation prevents unwanted emis-
sions from the crankcase of the engine from enter-
ing the ambient atmosphere. These emissions are re-
turned from the crankcase to the intake tract. There,
the emissions are mixed with the intake air and then
burned in the engine.
Catalytic converters
The catalytic converters are effective "cleaning devi-
ces" installed in the exhaust system of the vehicle.
The catalytic converters burn the undesired pollu-
tants contained in the exhaust gases before they
enter the atmosphere.
The exclusive use of unleaded fuel is of crucial im-
portance for the shelf life of the catalytic converters.
For this reason, only use unleaded fuel.
The catalytic converters will be damaged under the
following circumstances:
–
Push on or towing the vehicle
–
Engine misfires
–
Switch off the ignition while driving
–
Driving till the fuel tank runs empty
–
Other unusual operating conditions
e
Do not continue driving your vehicle under these
conditions, as unburnt fuel may enter the cata-
lytic converters. This could cause the catalytic
converters to overheat. The use of leaded fuel for
this vehicle is prohibited under federal law.
Fuel consumption
The fuel consumption depends on where, when and
how you drive, how the vehicle is equipped and the
general condition it is in.
A vehicle that has been coordinated and properly
maintained as specified helps to achieve optimum
fuel consumption values.
e
Have your vehicle tuned according to the specifi-
cation.
–
The air cleaner must be free of dirt so that
the engine can "breathe" freely.
–
The battery must be fully charged.
–
The track must be adjusted correctly.
–
Tires must be inflated at the correct pres-
sure.
e
Always monitor your fuel consumption.
e
Develop a smooth driving style and avoid speed
changes if possible.
e
Avoid "racing starts" and abrupt stopping.
e
Do not drive in low gears for longer than nec-
essary. Early upshifting without tormenting the
engine helps to save fuel.
e
Long "warm-run phases" when the vehicle is sta-
tionary are fuel waste. Do not start the vehicle
until you are ready to drive off. Accelerate slowly
and gently.
e
Switch off the engine if the vehicle is stationary
for an extended period of time.
e
Additional weight carried in the vehicle increases
fuel consumption. Always keep the load to a
minimum and take out all unnecessary things.
e
Organize your journeys so that you can carry out
several tasks per journey.
e
Every electrical accessory increases fuel con-
sumption.
e
Only switch on the air conditioning if necessary.
Roadside Assistance
e
Only drive with the roof transport system fitted if
you need it.
The consumption value in miles per gallon (mpg) es-
timated by the EPA is used for comparison purposes.
The actual value may differ from the estimated value
depending on the driving speed, weather conditions
and trip length. Your actual consumption on high-
ways (highway mileage) may be below the estimated
value.
e
Observe all local and national speed limits.
