by LEDs: Green LEDs, red LEDs and a field between
them with extinguished LEDs.
Use the green zone for normal driving.
Use the extinguished zone for engine braking.
Never let the engine go into the red zone.

Charge pressure gauge
To give good fuel economy, the needle should stay
still when driving on a flat road.

Oil pressure gauge
If the warning lamp lights up stop immediately and
switch the engine off! Investigate the cause. If the
lamp lights while the engine is running, an acoustic
alarm sounds. In addition the STOP lamp lights and a
warning message is shown on the display.
When driving with the engine at normal temperature,
the needle should stay between 3 and
5.5 bar
(300–
550 kPa). The oil pressure may drop when the engine
is idling. This is not dangerous if the oil pressure
increases again when engine speed increases.
