Fluids

WARNING

Never remove the radiator cap while the engine is warm. Wait until the vehicle cools.

If it is necessary to top up the coolant when the engine is warm, unscrew the expansion tank cap slowly so that the overpressure dissipates.

Fluid type: DOT 4+ boiling point >536 °F (>280 °C), P/N 9437433.

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.).

Always entrust brake fluid changing to a trained and qualified Volvo service technician.

If the fluid level is below the MIN mark in the reservoir or if a brake-related message is shown in the information display: DO NOT DRIVE. Have the car towed to a trained and qualified Volvo service technician and have the brake system inspected.

Dot 4+ should never be mixed with any other type of brake fluid.
