NOTICE:

Immediately after installing the brake pads, the braking performance may be reduced. Always perform a road test in a safe place while paying attention to the surroundings.
After replacing the rear disc brake pads, the brake pedal may feel soft due to clearance between the rear disc brake pads and rear disc. Depress the brake pedal several times until the brake pedal feels firm.
After replacing the rear disc brake pads, always perform a road test to check the braking performance and check for vibrations.
When removing or installing the front disc brake cylinder assembly, pushing back the disc brake piston may cause a large clearance between the brake pads and brake disc. When the brake pedal is depressed with a large clearance between the brake pads and the brake disc, DTC C140000 and/or C140A00 related to abnormal brake fluid pressure may be stored. Make sure to clear any DTCs after performing this procedure. (w/o vacuum brake booster)
While the auxiliary battery is connected, even if the power switch is off, the brake control system activates when the brake pedal is depressed or any door courtesy switch turns on. Therefore, when servicing the brake system components, do not operate the brake pedal or open/close the doors while the auxiliary battery is connected. (w/o vacuum brake booster)
After the ignition switch is turned off, the navigation system requires approximately a minute to record various types of memory and settings. As a result, after turning the power switch off, wait a minute or more before disconnecting the cable from the negative (-) auxiliary battery terminal. (w/o vacuum brake booster)
