I see this, but couldnt find in the car
Oooo .... that's most interesting, David. Good catch.
You have a Left-Hand drive Atto 3?
That low voltage disconnect (orange square with internal yellow square containing the disconnect symbol) in the front passenger area only shows on the Rescue Sheet for the Left-Hand Drive Atto 3.
It's not shown in the Right-Hand Drive Atto 3. And that's because in the RHD Atto 3 the low voltage (12 Volt) battery is in the engine compartment. The Rescue Sheet for the LHD Atto 3 shows two (2) low voltage disconnects, one in the engine compartment and one in the cabin in the front passenger area.
I live in a RHD jurisdiction. So I've only seen Atto 3 with the low voltage battery in the engine compartment and the low voltage disconnect being at the negative pole of that battery.
So .... I suspect that either (1) all or some LHD Atto 3 have a low voltage disconnect in the cabin; or (2) that is a mistake in the Rescue Sheet.
If you look at the Rescue Sheet for the LHD Dolphin, you'll see that Dolphins do have two low-voltage disconnects. One is in the engine compartment, at the box that houses fuses. The second is under the rear passenger seat, where the low voltage battery seems to be quite inconveniently located!
Given my ignorance and lack of experience with LHD Atto 3, I can only suggest you talk to your local BYD distributor or dealer. Either the Rescue Sheet is in error or some (or all) LHD Atto 3 are not just mirror reflections of RHD Atto 3.
