Tachometer (Engine rpm)
Do not exceed the maximum permissible engine speed.
NOTE: To protect the engine, its fuel supply is
interrupted when the maximum rpm is reached.
Despite this, the maximum rpm can still be exceeded in
overrun mode (e.g. when driving downhill).
Coolant Temperature Gauge
The coolant temperature is displayed when the key is
in position 2 in the ignition lock.
If corrosion inhibitor/antifreeze is present in the
correct concentration in the coolant, the coolant
temperature will be between 185 °F (+85 °C) and
250 °F (+120 °C), depending on operating conditions.
If the needle reaches the red section, do not continue to
drive the vehicle.
