Solution

1. Preparation

Ensure the engine is completely cool before proceeding.
Gather necessary tools (if needed) such as a flashlight for visibility.

2. Inspect Coolant Reservoir

Locate the coolant reservoir, usually a translucent plastic tank on the passenger side near the engine.
Check the coolant level against the "MIN" and "MAX" markings on the side of the reservoir.
If the coolant is below the "MIN" mark, proceed to the next step.

3. Add Coolant

Remove the coolant reservoir cap carefully to avoid pressure release (if the engine was recently running).
Use a funnel to prevent spills and add the appropriate coolant mixture (typically a 50/50 mixture of distilled water and ethylene glycol-based coolant) until the level reaches the "MAX" mark.
Replace the cap securely.

4. Check for Leaks

Inspect the area around the coolant reservoir and engine for any signs of leaks.
If leaks are present, further diagnosis may be needed to locate the source.
