Automatic engine switch-off
The ECO start/stop function switches the engine off automatically if the vehicle is braked to a standstill and the brake remains depressed with the transmission in position D or N.
You can still activate the HOLD function
when the vehicle is stationary, even if the
engine has been switched off
automatically. It is then not necessary to
continue applying the brakes during the
automatic stop phase. When you depress
the accelerator pedal, the engine starts
automatically and the braking effect of the
HOLD function is deactivated. Depress the
accelerator pedal carefully, as the engine
must be started first.
The engine is only switched off if:
• the outside temperature is within the range which is suitable for the system.
• the engine is at normal operating temperature.
• the set temperature for the vehicle interior has been reached.
• the battery is sufficiently charged.
• the system detects that the windshield is not fogged up when the air-conditioning system is switched on.
• the hood is closed.
• no engine-relevant diagnostics are active.
• the driver's door is closed and the seat belt is fastened.
