OWNER ANSWER
Where do I switch on low beam in the BYD ATTO 2?
On the electric ATTO 2, open Light → Exterior Light on the centre screen and select Low Beam. If Auto switches the lights on later than you need, select Low Beam yourself before driving into poor visibility.
For the battery-electric ATTO 2 covered by the July 2025 right-hand-drive handbook. Check the matching handbook if your controls differ.
- While parked, open Light → Exterior Light and select Low Beam.
- Confirm that both dipped headlights are on, using a reflection or a check from outside once the car is secured.
- If manual Low Beam works but Auto behaves unexpectedly, check that the light sensor area at the top of the windscreen is clear. Compare what happens in normal use and note the conditions.
What success looks like
Both dipped headlights come on when you select Low Beam. That gives you a way to turn them on when needed even if Auto has not switched them on yet.
If that did not work
If manual Low Beam works but Auto still switches on later than expected, tell BYD when it happens, whether the sensor area is clear and which software version you have. Ask them to check the automatic lighting function. If a headlight fails in manual mode too, say whether one or both are affected and ask for the lamp and its control to be checked. BYD’s handbook gives no owner adjustment for the Auto light threshold.
Safety note: Use headlights when visibility is seriously reduced. If you cannot get the lighting you need, stop safely and arrange help.
