Solution

1. Preparation

Ensure the vehicle is parked on a level surface.
Wait for the engine to cool completely to prevent injury.

2. Locate Coolant Reservoir

Open the hood of the vehicle.
Identify the coolant reservoir; it is usually a clear tank marked with a "coolant" symbol.

3. Check Coolant Level

Look at the side of the reservoir to find the minimum and maximum level markings.
Ensure the coolant is between these two levels. If below the minimum mark, proceed to the next step.

4. Add Coolant (if necessary)

Tools Required: Funnel for pouring coolant.
Parts Required: Appropriate coolant (check owner's manual for specifications).
Open the reservoir cap slowly to release any pressure.
Using a funnel, add the recommended coolant until it reaches the maximum mark.
Replace and tighten the cap securely.
