Can a Vehicle Be Locked Without Turning Off the Engine?

[MacKylie]

It is not advisable to lock a vehicle without turning off the engine, even though some models may allow it. When a car remains stationary for an extended period with the engine running, the accumulation of exhaust fumes can potentially enter the cabin through the air intake vents. This poses a serious risk if someone is accidentally locked inside the vehicle. Methods to prevent forgetting to turn off the engine when exiting the car: 1. Check the tachometer and display screen—ensure the display is turned off and dark, and the tachometer reads zero before leaving; 2. Adjust the steering wheel position—avoid setting it too high, as the wheel will rise when the engine is turned off; 3. Use daytime running lights—enable them in the light settings. If the daytime running lights remain off after locking the doors, it confirms the engine is off.
