When starting the engine, you should release the key or start button after the engine starts.

• A. After the engine starts idling
• B. When the engine reaches full RPM
• C. Only after the engine stops
• D. Immediately after the engine starts

Answer: (D)

Starting the engine is meant to be a quick crank until the engine fires, then the starter should be disengaged. Releasing the key or start button immediately after the engine starts prevents the starter from continuing to run, which can overheat the starter, wear out the electrical components, and drain the battery. Once the engine is running on its own, it will settle into idle and you can continue with normal operation. Holding the starter past the moment it fires isn’t needed and can cause damage, whereas releasing right away keeps things safe and efficient. If it doesn’t start within a few seconds, stop cranking and try again after a brief pause.
