Before operating the Subaru Ascent, it is essential to carry out a series of routine checks and adjustments each day. These simple steps help ensure safety, reliability, and optimal performance while driving.
1. Inspect all windows, mirrors, and exterior lights of the Subaru Ascent to confirm they are clean, clear, and free from obstructions that could impair visibility.
2. Examine the tires for any visible damage or irregular wear, and verify that all tires are properly inflated according to the recommended pressure for the Subaru Ascent.
3. Look beneath the Subaru Ascent for any signs of fluid leakage, such as oil, coolant, or other automotive fluids, which may indicate a potential issue requiring attention.
4. Before starting the engine, check the engine compartment carefully to ensure that no small animals have entered or are hiding inside, as this could lead to damage or malfunction.
5. Confirm that both the hood and the rear gate of the Subaru Ascent are securely closed and properly latched.
6. Adjust the driver’s seat to a comfortable and safe position that allows full control of the steering wheel, pedals, and visibility.
7. Properly set both the inside rearview mirror and the outside mirrors to achieve the best possible field of vision while driving the Subaru Ascent.
8. Fasten your seatbelt securely and ensure that all passengers in the Subaru Ascent are also properly restrained before the vehicle begins moving.
9. Turn the ignition to the "ON" position and verify that all warning and indicator lights illuminate briefly, confirming proper system operation.
10. After starting the engine, check the gauges and indicator lights in the Subaru Ascent to ensure that all systems are functioning normally and no warnings remain active.

Small animals trapped near the cooling fan, belts, or engine components of the Subaru Ascent can cause serious damage or malfunction. Always inspect the engine compartment and area beneath the vehicle before starting the engine.
