Solution
1. Preparation
  • Gather tools such as a funnel, clean cloth, and possibly a socket set for reservoir caps.
  • Ensure the vehicle is parked on a level surface and the engine is cool.
2. Check and Refill Brake Fluid
  • Inspect the Brake Fluid Reservoir:
    • Locate the brake fluid reservoir, typically found near the driver's side near the back of the engine bay.
    • Check the fluid level against the minimum and maximum markings.
  • Refill if Necessary:
    • If low, use the appropriate brake fluid type (DOT 3 or DOT 4 as specified in the owner's manual).
    • Use a funnel to pour the fluid into the reservoir without spilling.
  • Secure the Cap:
    • Ensure the reservoir cap is tightly secured after refilling.
3. Check and Refill Coolant
  • Inspect the Coolant Reservoir:
    • Locate the coolant reservoir, usually a translucent tank near the front of the engine compartment.
    • Assess the fluid level against the minimum and maximum indicators.
  • Refill if Necessary:
    • If low, add the recommended coolant type (check the owner's manual for specifications).
    • Use a funnel to prevent spills while pouring.
  • Check for Leaks:
    • After refilling, visually inspect for any leaks around hoses and connections.
4. Check and Refill Windshield Washer Fluid
  • Inspect the Windshield Washer Fluid Reservoir:
    • Locate the washer fluid reservoir, typically marked with a windshield icon.
    • Check the fluid level; if low, add washer fluid.
  • Refill if Necessary:
    • Use a funnel and pour the washer fluid into the reservoir until it reaches the fill line.
5. Check and Refill Power Steering Fluid (if applicable)
  • Inspect Power Steering Fluid Reservoir:
    • Locate the power steering fluid reservoir (if equipped).
    • Assess the fluid level and add fluid if necessary, following the owner's manual for the correct type.
