Solution

1. Preparation

Ensure the engine is completely cool before proceeding.
Gather necessary tools: a clean funnel, coolant (if needed), and a rag for cleaning spills.

2. Inspect Coolant Reservoir

Locate the coolant reservoir on the driver's side of the engine bay.
Visually assess the coolant level through the reservoir's side markings. The level should be between the "MIN" and "MAX" marks.

3. Top Off Coolant (if necessary)

If the level is below the "MIN" mark, remove the cap from the coolant reservoir carefully.
- Caution: Never open a hot coolant reservoir cap; wait until the engine is cool.
Using a clean funnel, pour the recommended coolant type (refer to your owner's manual for specifications) into the reservoir until it reaches the "MAX" mark.
Replace the cap securely.

4. Clean Up

Wipe any spills with a rag to prevent slips and keep the engine bay clean.
Dispose of any used rags and coolant residue according to local regulations.
