Driving
Avoid driving at high speed
Avoid travelling at top speed. Fuel consumption,
exhaust emissions and noise Levels all increase
very rapidly at higher speeds. Driving at moder­
ate speeds will help to save fuel.
Do not let the engine idle for longer than
necessary
Engine idling periods are automatically reduced
on vehicles with start/stop system*. On vehicles
without start/stop system*, it is worthwhile
switching off the engine at Level crossings, for in­
stance, or at traffic Lights with a Long red phase.
The fuel saved after only 30 - 40 seconds is
greater than the amount of fuel needed to re­
start the engine.
The engine takes a very Long time to warm up
when it is running at idling speed. Mechanical
wear and pollutant emissions are also especially
high during this initial warm-up phase. It is
therefore best to drive off immediately after
starting the engine. Avoid running the engine at
high speed.
Regular servicing
Regular servicing can establish a basis for good
fuel economy before you start driving. A well­
serviced engine gives you the benefit of
proved fuel efficiency
as well as maximum relia­
bility and an enhanced resale value.
A poorly maintained engine can consume up to
ten percent more fuel than necessary.

depends to a great extent on the en­
gine Load and engine speed. It is quite normal
that the oil consumption of a new engine only
reaches its lowest level after a certain mileage.
This means that the oil consumption can only be
properly assessed after about 5,000 km. Depend­
ing on your personal driving style, oil consump­
tion can be up to 0.5 Ltr./1,000 km.

Check tyre pressures
Always make sure the tyres are inflated to the
correct tyre pressures to save fuel. If the tyre
pressures are just 0.5 bar too Low, this can in­
crease the fuel consumption by as much as 5 %.
Due to the greater rolling resistance, under-infla­

Save electrical energy
The engine drives the alternator to generate elec­
tricity. This means that fuel consumption rises

ment. Switch off electrical equipment when it is
