The warning and indicator lamps indicate various warnings, faults or certain functions. Some 
warning and indicator lamps light up when the ignition is switched on and must go out once the 
engine is running or the vehicle is in motion. 
Depending on the vehicle equipment level, symbols may be displayed in the instrument cluster 
instead of warning lamps.

The vehicle is equipped either with an analogue or a digital instrument cluster (Active Info Display). 
When you start the engine after the 12-volt battery has been totally discharged or changed, you may 
find that system settings (time, date, personal convenience settings and programming) have been 
changed or deleted. Check and correct the settings as necessary once the 12-volt vehicle battery has 
been sufficiently charged. 
 
WARNING 
Accidents and injuries can occur if the driver is distracted. 
Never press the buttons on the instrument cluster while the vehicle is in motion. 
Any settings for the instrument cluster display and displays in the Infotainment system should be 
made only when the vehicle is stationary in order to reduce the risk of accidents and serious injuries.

Rev counter 
First read and observe the introductory information and safety warnings
Rev counter 
The start of the red zone on the rev counter indicates the maximum engine speed that may be used 
in each gear when the engine is warm and after it has been run in properly. You should change up a 
gear or move the selector lever to D/S (or lift your foot off the accelerator) before the needle 
reaches the red zone

When the engine is cold, avoid high engine speeds, driving at full throttle and overloading the 
engine. 
The needle on the rev counter should only briefly point into the red area, as engine damage may 
otherwise be incurred. 
 
Changing up a gear early will help to save fuel and reduce engine noise. 
 
Digital instrument cluster (Active Info Display) 
First read and observe the introductory information and safety warnings
The Active Info Display is a digital instrument cluster with high-resolution TFT colour display. To 
complement the standard dials such as the rev counter and speedometer, users can choose from 
various "information profiles" to view additional data.
