2. Address the underlying issues indicated by the warning lights (e.g., low oil pressure, engine temperature, etc.).

3. Inspect Door and Hood Latches

Open and close all doors and the hood:
1. Ensure they are fully latched.
2. Check for any obstructions or damage to the latches that may prevent them from closing properly.

4. Battery Connection Check

Inspect battery connections:

2. Clean any corrosion from the terminals using a wire brush.
3. Reconnect the terminals securely, ensuring they are tight and free from corrosion.
