The gearbox shifts down one or more gears depending on the vehicle speed
and engine speed, and the vehicle accelerates.
The gearbox does not shift up into the highest gear until the engine has
reached its maximum revolutions for this gear range.

In the MAXI DOT display in the menu Settings activate the menu item Coast-
ing » page 46.

Move the selector lever into the position D.
›
Remove your foot from the accelerator pedal (the speed is higher than 20
km/h).
The vehicle moves without the braking effect of the engine.
The gear is automatically inserted again by depressing either the accelerator
or brake pedal.
This function is not available when towing a trailer or when another accessory
is connected to the trailer socket.
WARNING
Rapid acceleration, particularly on slippery roads, can lead to loss of control
of the vehicle – risk of accident!
Running-in and economical driving
Introduction
This chapter contains information on the following subjects:

Tips for economical driving 126
The fuel consumption, degree of pollution and vehicle wear depend on driving
style, road condition, weather conditions and the like.
Running-in
Driving in the engine
The engine has to be run in during the first 1 500 kilometres. During this peri-
od, the driving style decides on the quality of the driving-in process.
During the first 1 000 km we recommend not driving faster than 3/4 of the
maximum permissible engine speed, not to drive at full throttle and to dis-
pense with the trailer.
In the area of 1,000 to 1,500 kilometres the engine load can be increased up
to the maximum permitted engine speed.
New tyres
New tyres must firstly be “run in”, as they do not offer optimal grip at first.
Therefore, drive especially carefully for the first 500 km or so.
New brake pads
New brake pads have to first “grind in” because these do not initially have the
best possible braking effect.
Therefore, drive especially carefully for the first 200 km or so.
Tips for economical driving
To achieve the lowest possible fuel consumption, the following instructions
must be observed.
Looking ahead when driving
Avoid unnecessary acceleration and braking.
Switch in an energy saving and timely manner
Observe the recommended gear » page 42.
Avoid full throttle and high speeds
Fuel consumption can be reduced by half if only three-quarters of the possible
top speed of your vehicle is used.
Reducing idling
If the vehicle is fitted with the START - STOP system there is an automatic re-
duction of the idling. If the engine is stopped on vehicles without START-STOP
system, such as when waiting in a traffic jam, the fuel economy is already
greater after 30 - 40 s than the fuel quantity which is required for engine re-
start.
