Solution

1. Preparation

Tools Required: Clean rag, flashlight (if necessary)
Ensure the vehicle is parked on a level surface and the engine is off.

2. Inspect Brake Fluid Reservoir

Remove the cap of the brake fluid reservoir carefully to avoid contamination.
Use a clean rag to wipe the cap and the area around the reservoir before opening to prevent dirt from entering.

3. Check Fluid Level

Look at the fluid level against the minimum and maximum markings on the reservoir.
If the fluid is below the minimum mark, additional fluid will need to be added.

4. Add Brake Fluid (if necessary)

Tools Required: Brake fluid compatible with your RAV4 (usually DOT 3 or DOT 4)
Using a funnel, add the appropriate brake fluid until the level reaches the maximum mark.
Do not overfill the reservoir.

5. Reassemble

Replace the cap securely on the brake fluid reservoir.
Clean up any spilled brake fluid immediately, as it can damage paint and other surfaces.
