Caution / Notice / Hint

NOTE:
  • Perform brake fluid replacement with the shift lever in P and the parking brake set.
  • Perform brake fluid replacement while adding fluid to maintain the fluid level between the MIN and MAX lines of the reservoir.
  • As brake fluid may overflow when fluid is released from the brake actuator, do not leave the brake fluid can in the reservoir filler opening when adding brake fluid.
  • If the brake pedal is depressed with the reservoir cap removed, brake fluid may overflow.
  • Do not allow brake fluid to come into contact with any painted surface. If contact occurs, wash off the fluid immediately.
  • When the brake fluid is replaced, DTCs may be stored. Therefore, after fluid replacement, always clear the DTCs and check that a normal system code is output.
