< PRECAUTION >

PRECAUTIONS

5. When the repair work is completed, return the ignition switch to the 

″LOCK″ position before connecting

the battery cables. (At this time, the steering lock mechanism will engage.)

6. Perform a self-diagnosis check of all control units using CONSULT-III. 

Precaution for Brake System

INFOID:0000000005147886

• Always use recommended brake fluid. Refer to 

MA-13, "Fluids and Lubricants"

.

• Do not reuse drained brake fluid.

• Be careful not to splash brake fluid on painted areas.

• To clean or wash all parts of master cylinder, disc brake caliper and wheel cylinder, use clean brake fluid.

• Do not use mineral oils such as gasoline or kerosene. They will ruin rubber parts of the hydraulic system.

• Use flare nut wrench when removing and installing brake tube.

• Always check tightening torque when installing brake lines.

• Before working, turn ignition switch to OFF and disconnect con-

nectors for ABS actuator and electric unit (control unit) or battery

terminals.

• Burnish the brake contact surfaces after refinishing or replacing

drums or rotors, after replacing pads or linings, or if a soft pedal

occurs at very low mileage. Refer to 

BR-30, "Brake Burnishing

Procedure"

.

• Clean brake pads and shoes with a waste cloth, then wipe

with a dust collector.
