Nissan X-Trail 2024 Owners Manual
7.6.3. Push-button ignition switch positions

Never place the ignition switch in the OFF position while driving. The steering wheel may lock and cause the driver to lose control of the vehicle, resulting in serious vehicle damage or personal injury.

Do not leave the vehicle for extended periods of time when the ignition switch is in the ON position and the engine is not running. This can discharge the battery.
Use electrical accessories with the engine running to avoid discharging the vehicle battery. If you must use accessories while the engine is not running, do not use them for extended periods of time and do not use multiple electrical accessories at the same time.

When the ignition switch is pushed without depressing the brake pedal, the ignition switch will illuminate.
Push the ignition switch centre:
once to change to ON.
two times to change to OFF.
When the ignition switch cannot be placed in the OFF position, proceed as follows:
Push the park button to shift to the P (Park) position.
Push the ignition switch. The ignition switch position will change to the ON position.
Push the ignition switch again to the OFF position.
The shift position can be shifted from the P (Park) position if the ignition switch is in the ON position and the brake pedal is depressed.
