Solution

1. Preparation

Gather tools required: clean rags, funnel, and brake fluid as specified by the manufacturer.
Ensure safety by wearing gloves and eye protection.

2. Inspect Brake Fluid Reservoir

Open the brake fluid reservoir cap carefully to avoid contamination.
Use a clean rag to wipe the reservoir cap before removal to prevent dirt from entering.
Check the fluid level against the minimum and maximum markings on the reservoir.

3. Add Brake Fluid (if necessary)

If the fluid level is below the minimum mark, use the funnel to add the specified brake fluid.
- Fluid Type: Refer to owner's manual for the correct brake fluid type (typically DOT 3 or DOT 4).
Fill until the fluid level reaches the maximum mark, avoiding overfilling.

4. Reassemble

Carefully replace the reservoir cap, ensuring it is securely fastened.
Clean any spilled brake fluid from the area using a clean rag.

5. Final Check

Close the frunk and check the brake warning light on the dashboard. It should remain off if the fluid level is adequate.
