Solution

1. Preparation

Ensure the vehicle is parked on a level surface.
Turn off the engine and allow it to cool if it has been running.
Gather necessary tools: clean cloth and flashlight.

2. Locate the Brake Fluid Reservoir

Open the hood of the RAV4.
Identify the brake fluid reservoir, typically located near the back of the engine bay, on the driver’s side.

3. Check Fluid Level

Inspect the transparent reservoir to view the fluid level.
Ensure the fluid is between the minimum and maximum marks. If it is below the minimum mark, proceed to the next step.

4. Add Brake Fluid (if necessary)

If the fluid is low, remove the reservoir cap carefully.
Use a funnel to add the appropriate type of brake fluid (usually DOT 3 or DOT 4, check owner’s manual for specifics).
Do not overfill; ensure the fluid level is again between the minimum and maximum marks.
Replace the reservoir cap securely.
