What to Do When the Electric Car Screen Stays On?

Turn the power on and then off, listen for a "beep" sound to deactivate the alarm; if you hear three "beep beep beep" sounds, repeat the process until you hear a single "beep" sound. When the display screen remains lit, it is often due to rain affecting it. First, deactivate the alarm, then visit an after-sales service station.

Last time I drove my friend's electric pickup, I also encountered the issue of the screen staying on. It took me quite a while to figure it out. First, you need to distinguish whether it's on while driving or after turning off the engine—these are completely different situations. If the screen doesn't turn off while driving, it might be a settings issue. Go to the vehicle control menu and look for the screen standby option; some electric vehicles are set to permanent display by default. If the screen stays glaringly bright after turning off the engine, it's most likely a system freeze. The solution I usually use is to press and hold the volume knob for 15 seconds to force a reboot of the infotainment system—just like when a smartphone freezes. If that doesn’t work, check if any modifications have been made to the wiring recently. Incorrectly installed dashcams with wrong fuse connections can also cause system abnormalities. Finally, a reminder: leaving it like this not only drains the battery but can also lead to screen overheating and aging in the summer. It's best to resolve it within three days.

As a commuter who has driven electric cars for three years, I have a say about the always-on screen issue. The first step is always to check the user manual, as different brands handle it quite differently. For example, some domestic cars can turn off the screen via voice command—just say 'turn off the display.' Physical button failures are usually due to static interference; I open the glove compartment, pull out the fuse, wait five minutes, and then plug it back in. Daily prevention is crucial—I avoid parking in direct sunlight and make it a habit to clean the edges and gaps of the screen with a microfiber cloth monthly to prevent dust buildup that could cause button sticking. If the system crashes, don’t panic—most cars have a hidden reboot combo, like holding the steering wheel menu button and voice command button together for ten seconds. If all else fails, schedule a service center visit—never attempt DIY disassembly.

My auto repair shop friend taught me a few tricks for dealing with screen malfunctions. First, observe if there are other abnormalities, such as touch failure or screen freezing, which may indicate a motherboard issue. Basic troubleshooting starts with the power source—disconnect the negative terminal of the small battery for five minutes and then reconnect it, which is equivalent to a complete power cycle for the car's infotainment system. On the software side, connect to a mobile hotspot to check for updates, as sometimes system updates can fix bugs. For hardware issues, pay special attention to the rain sensor, as a faulty sensor can mislead the system into thinking it's raining, forcing the screen to stay on constantly. If you've modified the audio system, be particularly cautious, as interference from amplifier wiring with the car's computer is common. Only professional diagnostic equipment can accurately pinpoint the fault codes.
