This is something you can command the car to do via the menus. From the touchscreen, find the menu for the car’s functions, scroll through until you find the relevant section for the mirrors and enable the self-folding function on locking. That should do the trick.

Good news; Haval extended its factory warranty to seven years back in 2018, meaning that your car is still under factory warranty. So make it Haval's problem. Assuming you haven't damaged the screen (and the car hasn't been under water or anything similarly drastic) and the failure has been caused by an electronic or hardware fault or flaw, Haval's warranty dictates it needs to fix it.

There's absolutely nothing wrong with having a non-Haval workshop service your vehicle and, provided the workshop is qualified, there will be no problems with any warranty claims down the track. In fact, the relative scarcity of Haval dealers in Australia means that many owners living in regional or remote areas have very little choice but to use a non-Haval service centre.

As far as the service reminder message goes, the solution is not so simple. While many makes and models have a simple method of cancelling this reminder (usually via the infotainment system and a series of menus) it appears the Haval H2 requires the Haval factory computer to achieve this. The message cancellation appears to be performed via the car's diagnostic port, rather than any simple method you could do at home. So, next time you're near a Haval dealer, drop in and have the message erased.
