Which actions are included in securing your vehicle?

Securing your vehicle primarily involves taking steps to protect it from theft or damage. Locking the doors ensures that unauthorized individuals cannot access the interior of the vehicle. Closing the windows prevents weather elements and potential intruders from entering. Ensuring the vehicle won't move, often involving placing it in park or using a steering wheel lock, protects it from theft and minimizes the risk of it rolling away.

The other options, while they may contribute to vehicle maintenance or protection in different contexts, do not encapsulate the essential actions of securing a vehicle as effectively. For instance, turning on the alarm and starting the engine does not ensure that the vehicle is secure; rather, it focuses on activating alarm systems, which is only part of a broader security measure. Parking in a garage and washing the vehicle pertain more to maintenance and protection from environmental factors than to security against theft. Lastly, checking fluid levels and cleaning headlights is a necessary part of vehicle upkeep but does not relate to securing the vehicle from unauthorized access.
