REPLACEMENT

CAUTION / NOTICE / HINT

NOTICE:

As brake fluid may overflow, do not leave the brake fluid can in the reservoir filler opening when adding brake fluid.
Do not allow brake fluid to come into contact with any painted surface. If contact occurs, wash off the fluid immediately.
Perform brake fluid replacement while adding fluid to maintain the fluid level between the MIN and MAX lines of the reservoir.
If bleeding is performed with the engine running or the ignition switch ON, DTC C1441 will be stored. Make sure to clear the DTCs when work is complete (for VSC).
