Why is the display screen still on after the Changan CS75 is turned off?

[LaErin]

Changan CS75's display screen remains on after turning off indicates that the start button was pressed twice, or the vehicle was turned off without shifting to P gear. Correct shutdown steps: 1. Step on the brake, stop the vehicle smoothly, shift the gear from D to N and tighten the handbrake; 2. Release the foot brake, but do not turn off the power, continue to step on the foot brake, shift the gear from N to P; 3. Release the foot brake, press the one-button start button, the power is turned off, and the shutdown is completed. The length, width and height of Changan CS75 are 4650mm, 1850mm and 1715mm respectively, the wheelbase is 2700mm, equipped with a 6-speed manual transmission, and the body type is a 5-door 5-seat SUV. The vehicle uses a 1.5T L4 turbocharged engine, the maximum torque of the engine is 265 Nm, and the driving method uses front-wheel drive.

I've been driving a Changan CS75 for several years. A while ago, I noticed the infotainment screen was still on after turning off the engine, and at first, I thought the car was broken, which really annoyed me. On second thought, this is actually how modern cars are designed - the screen stays on for a few seconds to minutes after shutdown as part of the normal energy-saving mode, allowing you to adjust settings or check status. If that's not the case, you should check whether the key wasn't completely turned to the off position or if the ACC power mode is stuck. Another possibility could be an issue with the battery management module, such as unstable voltage or a software bug preventing power cut-off. I remember one time this problem lasted for several minutes, but after taking it to the 4S shop for inspection, replacing a relay fixed it. In short, don't panic when this happens - wait to see if it's just normal delayed shutdown. If the screen stays on for more than 5 minutes, take it to a professional repair shop immediately to avoid accidentally draining the battery and affecting the next day's startup.

I have some knowledge about automotive circuits. There are various reasons why the CS75's screen stays on after the engine is turned off. The most common is that the vehicle's power system is not completely cut off, such as a delayed release of the relay or software settings that automatically retain the display function. In terms of design, this allows you to operate the media or reverse camera before locking the car. However, if the screen stays on abnormally, it could be due to the relay contacts sticking and not disconnecting or aging fuses causing residual current. Additionally, if the car key is not positioned correctly, some power modes may not be turned off, leading to this issue. I recommend manually restarting the vehicle and trying again. If it's a new car, it's mostly a normal function; for older cars, be cautious about whether the battery voltage is too low. For a simple self-check, I can wait a few minutes to see if the screen turns off. If it remains on, it's best to use a multimeter to test the circuit or have a technician check the ground wire to avoid minor issues turning into major problems.

As a car owner, I'm concerned about potential safety hazards when the display screen remains on after turning off the engine. For instance, prolonged screen illumination can quickly drain the battery, which would be troublesome if the car breaks down outdoors. The CS75 might have a delayed shutdown mechanism, but if the abnormality persists, it could indicate a power control system failure, such as relay sticking or circuit shorting. I've encountered similar situations before, which turned out to be the key not being turned completely off. The solution is simple: make sure the key is fully in the off position and wait a few minutes; if the screen still stays on, immediately disconnect the negative battery terminal to temporarily prevent drainage, then seek repair as soon as possible. Such issues shouldn't be neglected as they can affect the overall lifespan of vehicle electronic systems. Mention this symptom during regular maintenance to prevent more serious problems.

When I first started using the car, I also encountered the issue of the CS75's screen staying on after turning off the engine, and I did some simple troubleshooting myself. The steps are straightforward: First, confirm that the key is turned to the off position to ensure no misoperation. Then, check the user manual to see if the manufacturer specifies a post-shutdown display delay feature. If that doesn't work, wait for 5 minutes to let it turn off automatically. If the screen is still on, inspect the corresponding fuse in the fuse box to see if it's blown. If you have the tools, unplug and restart the system. If the problem persists, it might be due to aging wiring or a faulty control module, and you'll need to visit a 4S shop for a diagnostic tool check. The whole process doesn't require professional tools, and even beginners can handle it, saving money. Regular vehicle maintenance and ensuring the battery is in good condition can help prevent such unexpected issues.

It's normal to find the screen still on after turning off the Changan CS75, as this is a common design in modern smart vehicles. The CS75 features a delayed screen shutdown of 5-10 seconds after engine-off for convenience, allowing you to check the time or complete system updates. Similar functions exist in other models, and this is not a malfunction unless the delay is unusually long. For new cars, there's no need to worry; in older vehicles, it might indicate low battery voltage causing system irregularities. I've found that restarting the vehicle can resolve the issue. If the screen stays on continuously, check for software updates to fix bugs or inspect if the relay is stuck. In daily use, avoiding excessive circuit modifications can reduce such occurrences. Overall, this is a product feature, and simply paying attention to the auto power-on/off behavior is sufficient.
