Solution

1. Preparation

Ensure the vehicle is parked on a level surface.
Gather necessary tools: a clean cloth for spills, and a flashlight for better visibility if needed.

2. Inspect Coolant Reservoir

Open the hood and locate the coolant reservoir, typically marked with a symbol indicating coolant.
Visually inspect the level against the "MIN" and "MAX" markings on the side of the reservoir.

3. Check Radiator Coolant Level

If the level in the reservoir is low, carefully remove the radiator cap using a clean cloth to protect your hands.
Inspect the coolant level inside the radiator; it should be at or near the top.
If the coolant is low, proceed to the next step.

4. Top Off Coolant

If necessary, add the appropriate coolant mixture (usually a 50/50 mixture of antifreeze and distilled water) to the reservoir or radiator.
Use a funnel to prevent spills and ensure proper filling.
Replace the radiator cap securely if it was removed.

5. Clean Up

Wipe any spills with a clean cloth to prevent slipping on the driveway.
Check the coolant reservoir cap for proper sealing and return it to its original position.
