Solution

1. Preparation

Gather tools: Clean cloth or paper towels.
Ensure the vehicle is parked on a flat surface and the engine is off.
Wear safety gloves to protect your hands.

2. Inspect Brake Fluid Level

Locate the brake fluid reservoir cap, which is usually labeled.
Wipe the area around the reservoir cap with a clean cloth to prevent dirt from entering.
Remove the cap carefully and check the brake fluid level against the "MIN" and "MAX" indicators on the reservoir.

3. Add Brake Fluid (if necessary)

If the fluid level is below the "MIN" mark, add the appropriate brake fluid:
- Use only DOT 3 or DOT 4 brake fluid as specified in your owner's manual.
Pour the brake fluid slowly into the reservoir until the level reaches the "MAX" mark, avoiding overfilling.
Replace the cap securely after adding fluid.

4. Clean Up

Wipe away any spilled brake fluid immediately, as it can damage paint and other surfaces.
Dispose of any used materials properly.
