Caution / Notice / Hint

WARNING:

The Techstream must be used for air bleeding. If not used, the air bleeding will be incomplete, which is hazardous and may lead to an accident.

NOTE:

Perform air bleeding with park (P) selected and the parking brake applied.
As brake fluid may overflow when bleeding, do not place the fluid can on the reservoir filler opening.
Perform air bleeding while maintaining the brake fluid level between the MIN and MAX lines on the brake fluid reservoir.
Air bleeding will be difficult if the following occurs:
1. The brake actuator hose (the hose between the brake booster pump assembly and brake master cylinder reservoir assembly) is higher than the fluid level and air enters the hose.
2. During the air bleeding procedure, air enters the brake booster pump assembly while the pump motor is operating.
While performing air bleeding, the accumulator pressure drop may cause a buzzer to sound. As there is no problem, continue with air bleeding.
During air bleeding, DTCs for pressure sensor malfunctions, etc. may be stored. After air bleeding and if instructed in the procedures, clear the DTCs.
When bleeding air from the brake fluid, to protect the pump motor, do not operate the pump motor continuously for more than 100 seconds. Then, release the brake pedal and temporarily stop the operation of the pump motor.
Release the parking brake before performing the linear valve offset calibration procedure.
Do not allow brake fluid on any painted vehicle body surface. If brake fluid leaks onto any painted surface, immediately wash it off.
Do not perform brake fluid air bleeding using a vacuum brake bleeder.

When bleeding air, select the suitable procedure according to the table below.
