BMW 3 Series 2020-2023 Engine-Off Coasting User Manual
Engine-Off Coasting
Principle
Under certain conditions the engine is automatically decoupled from the transmission in the D selector lever position. The vehicle continues traveling with the engine idling to reduce consumption. Selector lever position D remains engaged. This driving condition is referred to as coasting. Under certain conditions, the engine will not be operated at idle while coasting but switched off automatically in vehicles with Mild-Hybrid technology. When the engine is switched off, the lettering READY is displayed in the instrument cluster. The vehicle continues to coast without consuming fuel. This driving condition is referred to as engine-off coasting. As soon as the brake or accelerator pedal is de‐pressed, the engine is automatically coupled to the transmission again.
General information
Coasting is a component of the ECO PRO driving mode. Coasting is automatically activated when ECO PRO driving mode is called via the Driving Dynamics Control. A proactive driving style helps the driver to use the function often and supports the efficient effect of coasting.
Functional requirements
The function is available in the speed range from approx. 16 mph/25 km/h to 100 mph/160 km/h.
The function is active if the following conditions are met:
- The accelerator pedal is not depressed or the accelerator pedal is released.
- Brake pedal is not depressed or only slightly depressed.
- The selector lever is in selector lever position D.
- Engine and transmission are at operating temperature.
- Active Cruise Control with Stop Go function, ACC, not activated.
Operation via shift paddles
Principle
The coasting driving condition can be influenced by the shift paddles.

Driving style analysis
Principle
The function helps develop an especially efficient driving style and to conserve fuel.
For this purpose, the driving style is analyzed. The assessment is done in various categories and is displayed on the Control Display.
This display will help you adjust your driving style and save some fuel.
General information
The current trip is assessed. To assist with an efficient driving style, ECO PRO tips are displayed during driving. The range of the vehicle can be extended by adjusting your driving style. This gain in range is displayed as a bonus range in the instrument cluster and on the Control Display.
Functional requirement
This function is available in ECO PRO driving mode.
Calling up the Driving style analysis
- “CAR”
- “Driving information”
- “Driving style analysis”
Display on the Control Display
The display of the Driving style analysis shows the efficiency of the Driving style. The more efficient the driving style, the more bars are displayed in color and the faster the bo‐nus range increases.
In contrast, a reduced number of bars will be dis‐played with an inefficient driving style.
Refueling
Vehicle features and options
This chapter describes all standard, country-specific and optional features offered with the series. It also describes features and functions that are not necessarily available in your vehicle, e.g., due to the selected options or country versions.

Follow the following when refueling
General information
Follow the fuel recommendation prior to refueling. When refueling, insert the filler nozzle completely into the filler pipe. Lifting up the filler nozzle during refueling causes:
- Premature switching off.
- Reduced return of the fuel vapors.
The fuel tank is full when the filler nozzle clicks off the first time. Make sure that the fuel cap is closed properly after refueling, otherwise the emissions warning light may light up. Follow safety regulations posted at the filling station.
Additional information:
Fuel quality, refer to page 350.
Safety information
NOTICE
With a driving distance of less than 30 miles/50 km the engine may no longer have sufficient fuel. Engine functions are not ensured anymore. There is a risk of damage to property, among other potential damage. Re‐fuel promptly.
NOTICE
Fuels are toxic and aggressive. Overfilling of the fuel tank can damage the fuel system. Painted surfaces may be damaged by contact with fuel. Escaping fuel can harm the environment. There is a risk of damage to property, among other potential damage. Avoid overfilling.
