Applies to: vehicles with automatic gearbox
Coasting mode disengages the engine from the gearbox, which means that you can save fuel by anticipating the traffic situation ahead. The vehicle coasts without the engine braking effect, with the engine ticking over at idle speed. You can let the vehicle coast when approaching a speed restriction in a built-up area, for instance.
Switching on coasting mode
Important: Selector lever must be in D, gradient must be less than 12 %.
Select efficiency mode in drive select*
link► (you only have to do this once).
Take your foot off the accelerator.
If you have selected the “on-board computer” display, the message Coasting mode will then appear. The gearbox automatically disengages the clutch at speeds above 20 km/h and lets the vehicle coast without the engine braking effect. The engine ticks over at idling speed while the vehicle is coasting.
Cancelling coasting mode
Press the brake pedal or accelerator.
To use the engine braking effect and overrun fuel cut-off again, all you need to do is tap the brake pedal briefly.
You can improve your fuel economy and help to reduce emissions by using a combination of the coasting mode (i.e. coasting with low fuel consumption on a longer stretch of road) and the overrun fuel cut-off (i.e. using the engine braking effect with no fuel consumption on a shorter stretch of road).
WARNING
- If you are approaching an obstruction when coasting, please remember that the vehicle will not slow down as quickly as usual when you take your foot off the accelerator – risk of accident!
- The vehicle can pick up speed if you are driving down a slope in coasting mode – risk of accident!
- If other people are using your car, you should draw their attention to the coasting mode.
Note
- Coasting is only available in efficiency* mode (drive select*).
- The message only appears when the current fuel consumption display is selected. The gear is no longer displayed when you are in coasting mode (e.g. E instead of E6).
- The coasting mode is deactivated temporarily on gradients of 15 % or steeper.
