One pedal drive
You control both braking and acceleration with the accelerator pedal when One pedal drive is active.

The braking behaviour changes through the use of the accelerator pedal. When you press the accelerator, the car accelerates as normal but releasing the pedal engages braking. The more you ease up on the pedal, the more braking action you get.
Regenerative braking is prioritised by One pedal drive. However, the disc brakes can be applied if the braking action demands it.
To conserve battery power, One pedal drive can be used in driving sessions where you expect to vary your speed.
Important
You can only use One pedal drive after buckling your seatbelt and selecting driving gear D. Otherwise, no braking force will be applied when you ease up on the accelerator, even if One pedal drive is enabled in settings.
Warning
Keep the brake pedal in mind
There is a limit to the braking force that can be applied by releasing the accelerator when using One pedal drive. For hard braking you need to use the brake pedal.
