Vehicles with smart key system:
Turn the “ENGINE START STOP” switch to ACCESSORY mode.

Depress the brake pedal.

Pry the cover up with a flathead screwdriver or equivalent.
To prevent damage to the cover, cover the tip of the screwdriver with a rag.

Press the shift lock override button.
The shift lever can be shifted while the button is pressed.
