1. Turn on the scooter and ride forward a few feet
2. Wait for about 5 seconds before holding the front brake, ASR button, and electric start button simultaneously. The ASR indicator will begin to flash slowly on the dashboard.
3. Accelerate to a steady 18-20mph and hold it there until the ASR indicator turns off. Throttle control is important here. If this process fails, you were likely not steady enough at maintaining the right speed.
4. Once the ASR indicator turns off, turn off the scooter and pull over to wait 30 seconds (minimum). Count 35-60 seconds just to be safe so you can do this in one try.
5. After the time has elapsed, turn the scooter on and start it up. You’ll see the ASR light is slowly flashing. When you begin to ride, it will disappear. This means your ASR traction control is calibrated.
If you would like to turn off traction control you can do so on the switch. If you see ASR on the dashboard solid, traction control is turned off/disabled. Use this for spirited riding, or if you are on an uneven surface like gravel, dirt, etc, so that the scooter will respond to your throttle inputs. Otherwise, you might as well leave ASR on in case you get into a sketchy situation on the street. It might keep you upright in an emergency. Be safe out there.
