Regular servicing
A poorly tuned engine uses an unnecessarily high amount of fuel.
Having your vehicle serviced regularly at a specialist garage enables you to satisfy
one of the requirements for economical motoring even before you set off on your
journey. Keeping your vehicle properly serviced not only has a positive effect on
the safety of your vehicle and maintaining its value, but also saves on fuel.
A poorly tuned engine can result in a fuel consumption which is 10 % higher than
normal.
The foreseen maintenance work should be undertaken exactly according to the
Service schedule by a specialist garage.
Also check the oil level after refuelling. Oil consumption is dependent to a consid-
erable extent on the load and speed of the engine. Oil consumption could be as
high as 0.5 litres/1 000 km depending on your style of driving.
It is quite normal that a new engine has a higher oil consumption at first, and rea-
ches its lowest level only after a certain running in time. It is therefore not possi-
ble to correctly assess the oil consumption of a new vehicle until after you have
driven about 5 000 km.
For the sake of the environment
● You can achieve additional improvements in your fuel economy by using high-
lubricity oils.
● Check the ground below your car at regular intervals to detect any leakages in
good time. Please have your vehicle inspected by a specialist garage if you find
any stains caused by oil or other fluids on the floor.

Driving Tips
General Maintenance
Avoid driving short distances
Short distances result in an above-average high fuel consumption.
–
Avoid driving a distance of no more than 4 km if the engine is cold.
The engine and catalytic converter must first have reached their optimal operat-
ing temperature in order to effectively reduce fuel consumption and pollutant
emissions.
The cold engine vehicle consumes approx. 15 - 20 litres/100 km of fuel immediate-
ly after starting. Fuel consumption drops to 10 litres/100 km after just 1 kilometre.
The engine reaches its operating temperature (outside temperature and engine
dependent) only after about 4 to 10 kilometres and the fuel consumption then
stabilizes. You should therefore avoid driving short distances whenever possible.
An important factor in this connection is also the ambient temperature. The
⇒ f ig. 118
shows the different fuel consumptions for the same distance, on the one
hand at +20 °C and on the other hand at -10 °C. Your vehicle has a higher fuel con-
sumption in winter than in summer.
Checking tyre inflation pressures
Tyres which are correctly inflated save fuel.
Always ensure that your tyres are inflated to the correct pressure at all times. The
rolling resistance will be increased if the tyre filling pressure is too low. This will
not only increase fuel consumption but also tyre wear and the driving behaviour
will worsen.
Always check the inflation pressure of the tyres when cold.
