Refer to VEHICLE CONTROL HISTORY (RoB) [11/2021 - ] | |
| Does not change to shift state M | Shift state is being changed to M from a state other than D | Refer to VEHICLE CONTROL HISTORY (RoB) [11/2021 - ] |
| Battery is discharged or voltage is low | Refer to ON-VEHICLE INSPECTION [11/2021 - ] | |
| Does not change to shift state N | The shift lever operation time was short | Hold the shift lever in N for a certain amount of time |

| While performing a shift lever operation, the shift state changed to a state not intended | After performing a shift operation, the shift lever was unintentionally pulled back to another position | Refer to VEHICLE CONTROL HISTORY (RoB) [11/2021 - ] |
| The shift state changed to N unintentionally | The shift lever returned to the home position too slowly | Check for objects hanging from the shift lever, modifications to the shift knob, foreign matter, etc. |
| The shift lever was operated while driving or moved due to an object hanging from it | Refer to VEHICLE CONTROL HISTORY (RoB) [11/2021 - ] | |
| The shift state was changed to D while reversing | ||
| The P position switch was repeatedly pressed while driving | ||
| The P position switch was unintentionally pressed and held while driving | ||
| The shift state was changed to R while driving forward | ||
| Battery is discharged or voltage is low | Refer to ON-VEHICLE INSPECTION [11/2021 - ] | |
| The shift state cannot be changed to D or R | The shift lever returned to the home position too slowly | Check for objects hanging from the shift lever, modifications to the shift knob, foreign matter, etc. |
| The shift lever was not moved fully or operation time was too short | Securely move the shift lever to each position. | |
| Engine was not running | Refer to VEHICLE CONTROL HISTORY (RoB) [11/2021 - ] | |
| The shift state was changed to D while reversing | ||
| The shift state was changed to R while driving forward | ||
| Battery is discharged or voltage is low | Refer to ON-VEHICLE INSPECTION [11/2021 - ] | |
| The brake pedal was not depressed or was depressed lightly | Refer to VEHICLE CONTROL HISTORY (RoB) [11/2021 - ] | |
| When the vehicle was stopped in shift state N, the brake pedal was depressed after the shift operation was performed. | ||
| When the vehicle was stopped in shift state N, the shift operation was performed at the same time the brake pedal was depressed. | ||
| The shift lever was operated while the accelerator pedal was depressed | ||
| When "Braking Power Low Stop in a Safe Place See Owner's Manual" is displayed on the multi-information display, despite depressing the brake pedal and moving the shift lever, "Press Brake to Shift" is displayed | Release the brake pedal and depress it again, and then operate the shift lever. | |
| Supply power does not turn off (while the ignition switch is ON) |
When shift state is in N, the ignition switch was pushed within a certain amount of time of moving the shift lever to N | Refer to VEHICLE CONTROL HISTORY (RoB) [11/2021 - ] |
