Using Lane Change Assistant safely on the BMW iX

Before making a lane change, you should always check for traffic.
Although the car’s sensors constantly watch your blind spot, don’t rely on this. You should still look over your shoulder before changing lanes.
The Lane Change Assist might also not work correctly if the sensors can’t detect at least one lane edge. This could happen in:

• Heavy rain, sleet, or snow
• Dusty areas or dust on the sensors
• Dirt roads
• Poorly maintained/unpainted roads
