CAUTION:
• Do not let brake fluid come into contact with the painted surface of the vehicle body. Wash away with water immediately and wipe off if it is spilled by accident.
• Avoid mixing brake fluid of different brands or different grades even from the same brand to prevent fluid performance from degrading.
• When refilling brake fluid, do not allow dirt or dust to get into the reservoir tank.
• Always use new SUBARU genuine brake fluid when replacing or refilling the fluid. Do not reuse drained brake fluid.
