- When the brake pedal is first depressed after replacing the brake pads or pushing back the disc brake piston, DTC C1214 may be stored. As there is no malfunction, clear the DTC. (for HV Model)
- 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. (for HV Model)
