Transfer Assembly Fluid, Brake Fluid Transfer Assembly Fluid The transfer assembly should be drained and refilled with new fluid when this service is indicated by a maintenance message on the information display. Always use Hypoid gear oil GL4 or GL5 with a viscosity of SAE 90 or 8090W, and have your dealer replace the transfer assembly fluid. Brake Fluid Check the brake fluid level in the reservoir monthly. Replace the brake fluid according to the time recommendation in the maintenance minder schedule. Always use Honda Heavy Duty Brake Fluid DOT 3. If it is not available, you should use only DOT 3 or DOT 4 fluid, from a sealed container, as a temporary replacement. Using any non-Honda brake fluid can cause corrosion and decrease the life of the system. Have the brake system flushed and refilled with Honda Heavy Duty Brake Fluid DOT 3 as soon as possible. Brake fluid marked DOT 5 is not compatible with your vehicle's braking system and can cause extensive damage. MAX MIN The fluid level should be between the MIN and MAX marks on the side of the reservoir. If the level is at or below the MIN mark, your brake system needs attention. Have the brake system inspected for leaks or worn brake pads. Maintenance 243
