Use the switch only if the M.U.T.-III is not available.
1. Raise the vehicle using a jack and support the specified points with a rigid rack.
2. Move the selector lever to “P” position, and turn on the power supply mode of the electric motor switch (but do not start the motor (Electric motor unit)).
3. Depress the brake pedal.
Do not operate the electric parking brake switch too quickly (wait for at least two seconds by the next switch operation). If yes, the ECU cannot recognise the switch operation. This may cause the indicator lamp or the warning lamp not to flash.

5. Operate the electric parking brake switch once to release the parking brake.
6. Press the brake auto hold switch 10 time or more as soon as possible, then perform the release operation of the electric parking brake switch once.

The multi-information display should show “PARKING BRAKE SERVICE REQUIRED”.
Once the system has entered the maintenance mode, the electric parking brake is released completely.
If you failed the operation of the switch and did not enter maintenance mode, repeat the procedure after 60 seconds have elapsed.
Do not operate the electric parking brake switch to apply the parking brake. If yes, the maintenance mode will be cancelled.
When the electric parking brake switch is pulled up even with the power supply mode of the electric motor switch OFF, the maintenance mode will be cancel
Release the brake pedal.
