What should be checked on the gear indicator of an automatic vehicle?

The gear indicator of an automatic vehicle is crucial for ensuring that the driver knows which gear the vehicle is currently in. This indicator typically displays positions such as Park, Neutral, Drive, and Reverse. Ensuring the accuracy of these indications is vital for safe vehicle operation. If the gear indicator inaccurately shows the vehicle is in "Park" when it is actually in "Reverse," it could lead to dangerous situations when attempting to start the vehicle or in situations requiring quick maneuvers.

Checking the gear accuracy ensures that all components of the transmission system are functioning correctly and that the driver can confidently shift between gears as necessary without confusion or risk of accidents. Conditions like a misaligned gear linkage or faulty indicators can lead to operational issues, emphasizing the importance of this check during inspection.

The other options relate to different vehicle functions that, while important for overall vehicle operation and safety, do not pertain specifically to the gear indicator's role in identifying the current gear selection accurately. The focus here is on the transmission's status, which directly impacts how the vehicle can be controlled.
