Your stroller is equipped with an automatic parking brake.
You can manually use this brake by stepping on it to toggle it on and off or use the companion app*.
The parking brake will also engage automatically after idling or in certain scenarios if the system has deemed the stroller and it’s occupants are at risk:
Wrong orientation - stroller is in an angle that it shouldn’t be in, for example flipped or fallen over.
User is out of range on a steep hill for extended period of time
User has let go and brake assist has not stopped the stroller after 1 meter
Internal diagnostics detects a system error (LEDs will rainbow too in this case)
* You may use the companion app to turn on/engage the brake, but a physical human action is needed to turn off / disengage the parking brake. This is for safety reasons.
