What should be performed before conducting vehicle maintenance?

Performing system checks and vehicle functions is crucial before conducting vehicle maintenance because it ensures that all systems are operating correctly and are safe to service. By assessing the functionality of critical components such as the engine, transmission, brakes, and electrical systems beforehand, potential issues can be identified early, preventing further damage and ensuring the safety of the personnel performing the maintenance.

Additionally, understanding the current state of a vehicle's systems assists in developing a more effective maintenance plan and allows for documentation of any existing problems that may need attention during the maintenance process. This practice aligns with standard operating procedures and safety regulations, reinforcing the importance of thorough pre-maintenance checks.

While inspecting tire pressure, checking fuel levels, and cleaning the exterior are valuable tasks, they do not provide the comprehensive assessment of the vehicle's operational status that system checks and function assessments do. Hence, prioritizing system checks contributes significantly to the overall maintenance strategy.
