Solution

1. Preparation

Gather all necessary tools and replacement fluids.
Park the vehicle on a level surface and engage the parking brake.
Ensure the vehicle is powered off and allow the engine to cool if necessary.

2. Inspect and Refill Windshield Washer Fluid

Locate the windshield washer fluid reservoir, typically marked with a blue cap.
Remove the cap and visually check the fluid level.
If low, refill with a suitable windshield washer fluid, ensuring it is mixed according to the manufacturer's specifications.

3. Check and Refill Coolant

Find the coolant reservoir, usually a translucent plastic tank.
Inspect the level; it should be between the minimum and maximum lines.
If low, carefully remove the cap (after the engine has cooled) and add the appropriate coolant mixture as specified in the owner's manual, ensuring to follow the proper ratio.

4. Inspect and Refill Brake Fluid

Locate the brake fluid reservoir, usually near the driver's side of the engine bay.
Check the fluid level; it should be between the minimum and maximum indicators on the reservoir.
If necessary, add brake fluid that meets the specifications listed in the owner's manual.

5. Address Leaks (if found)

Identify the source of any leaks; this may involve inspecting hoses, connections, and seals.
Replace any damaged hoses or seals as needed. Ensure all connections are tight and secure.
