Checking Brake Fluid Level
Brake System:
The brake fluid level should be between the MIN and MAX marks.
Fluid type: DOT 4+
Replace: Every second year or 30,000 miles (48,000 km). The fluid should be replaced once a year or every 15,000 miles (24,000 km) when driving under extremely hard conditions (mountain driving, etc.)
Check, without removing the cap, that the level is above the "MIN" mark of the fluid reservoir.
Always entrust brake/clutch fluid changing to an authorized Volvo retailer.
