Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is completely cool.
Gather tools: a clean cloth or paper towel.

2. Locate Coolant Reservoir

Open the hood by pulling the hood release lever inside the vehicle.
Secure the hood with the prop rod.
Identify the coolant reservoir, which is typically a translucent plastic tank located near the radiator.

3. Inspect Coolant Level

Look at the markings on the side of the coolant reservoir. They are usually labeled "LOW" and "FULL."
If the coolant is below the "LOW" mark, it needs to be topped up.

4. Add Coolant (if necessary)

If coolant needs to be added, ensure you use the correct type for your vehicle (typically a 50/50 mix of Toyota Super Long Life Coolant).
Remove the cap of the coolant reservoir.
Using a funnel, carefully pour the coolant into the reservoir until it reaches the "FULL" mark.
Replace the cap securely.

5. Check for Leaks

After adding coolant, inspect the area around the reservoir and hoses for any leaks or drips.
Close the hood, ensuring it is securely latched.
