If you exceed the maximum permissible
engine speed, a warning tone will sound.
Avoid driving in the red engine speed

range (danger zone).

If the W indicator lamp on the instrument clus‐
ter lights up, the engine speed is high, e.g. when
you shift down to a lower gear.
Observe further information in the event window
of the on-board computer.
Reduce the vehicle speed with the service brake
or shift to a higher gear.
The W indicator lamp on the instrument clus‐
ter will go out.
General driving instructions for the rev counter:
Keep an eye on the rev counter while driving
R
and stay within the economical operating
range 1.
In some situations, it may make sense to
operate the engine outside the economical
operating range, e.g. on uphill gradients or
when overtaking.
If you drive the vehicle within the economical
R
operating range 1, you will achieve low fuel
consumption and reduced wear.
In engine braking mode, drive in the engine
R
speed range 2. The maximum engine brak‐
ECO support
ing effect will be achieved just before the red
danger zone 3.
When driving downhill, make sure that the
R
engine speed does not enter the red danger
zone 3.
Idle speed will be set automatically depending
R
on the coolant temperature.
When the vehicle is stationary, the engine is
R
running and the transmission is in neutral, the
engine will accelerate only slowly.
