Solution

1. Preparation

Gather necessary tools: flashlight, socket set, and a wrench set.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to reset the vehicle's computer (optional).

2. Inspect and Tighten Gas Cap

Locate the gas cap on the fuel filler neck.
Remove the gas cap and inspect it for cracks or damage.
Clean the sealing surface with a cloth, then securely reattach the gas cap until it clicks.

3. Check Engine Oil

Open the hood and locate the dipstick.
Remove the dipstick, wipe it clean, insert it back into the tube, and then remove it to check the oil level.
If oil is low, add the manufacturer-recommended oil type until it reaches the full mark on the dipstick.

4. Inspect Battery Connections

Locate the battery and inspect the terminals.
If corrosion is present, clean it using a mixture of baking soda and water, then rinse and dry.
Tighten any loose connections using the appropriate wrench.

5. Reset Check Engine Light

Reconnect the negative battery terminal if it was disconnected earlier.
Start the engine and allow it to run for a few minutes to see if the check engine light turns off.
