Caution / Notice / Hint

NOTE:
  • The brake fluid level must always be adjusted to the MAX line.
  • Adjust the brake fluid level so that the brake fluid level is at the MAX line with the power switch on (IG).
  • Perform brake fluid replacement with the shift lever in P and the parking brake applied.
  • As brake fluid may overflow when replacing brake fluid, do not place the brake fluid can on the brake master cylinder reservoir assembly filler opening.
  • Perform brake fluid replacement while maintaining the brake fluid level between the MAX and MIN lines on the brake master cylinder reservoir assembly.
  • Replacing brake fluid will be difficult if the following occurs:
    1. The No. 2 brake actuator hose (the hose between the brake booster pump assembly and brake master cylinder reservoir assembly) is higher than the brake fluid level and air enters the No. 2 brake actuator hose.
    2. During the brake fluid replacement procedure, air enters the brake booster pump assembly while it is operating.
  • While performing brake fluid replacement, the accumulator pressure drop may cause a buzzer to sound. As there is no problem, continue with brake fluid replacement.
  • During brake fluid replacement, DTCs for pressure sensor malfunctions, etc. may be stored. After brake fluid replacement and if instructed in the procedures, clear the DTCs.
  • Do not allow brake fluid on any painted vehicle body surface. If brake fluid leaks onto any painted surface, immediately wash it off.

HINT: 

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