What is an important step to take after using the vehicle daily?

After using the vehicle daily, draining the air system is a vital step, especially for vehicles like the Joint Light Tactical Vehicle (JLTV), which utilize an air brake system and other pneumatic components. Over time, moisture and contaminants can accumulate in the air system, potentially leading to reduced performance, corrosion, and maintenance issues. Regularly draining the air system helps ensure that the air lines remain clear of debris and moisture, maintaining the integrity and reliability of the braking system.

While other maintenance tasks, such as inspecting tires, checking oil levels, and washing the exterior, are also important for the vehicle's overall upkeep, they might not directly address the specific requirements after daily usage related to the air system. Proper air system maintenance is crucial for operational safety and efficiency, making it a priority following routine vehicle use.
