Caution / Notice / Hint

NOTE:

Perform fluid replacement with park (P) selected and the parking brake applied.
Perform fluid replacement while maintaining the brake fluid level between the MAX and MIN lines on the brake fluid reservoir.
When the No. 2 brake actuator hose (the hose between the brake booster pump assembly and brake master cylinder reservoir assembly) is higher than the fluid level, air enters the hose and brake booster pump assembly while the pump motor is operating and it is difficult to replace brake fluid.
When performing fluid replacement, the accumulator pressure drop may cause a buzzer to sound. As this is not a malfunction, continue with the fluid replacement.
If fluid replacement is performed, a motor drive permission malfunction or accumulator low pressure DTC may be stored. Clear the DTCs after performing fluid replacement or whenever specified by a procedure.
Do not allow brake fluid to contact any painted surface. If brake fluid leaks onto any painted surface, immediately wash it off.
When performing fluid replacement, do not continuously operate the pump motor for more than 100 seconds. If the pump motor is operated for more than 100 seconds, release the brake pedal to stop operation of the pump in order to prevent damage to the pump motor.
As brake fluid may overflow from the reservoir when brake fluid is released from the accumulator, do not invert and place the brake fluid bottle on the reservoir filler opening.

HINT:

There are 2 ways of brake fluid replacement: using the Techstream or not using the Techstream.
