Your vehicle has an electronically controlled steering wheel lock that automatically operates.
The steering wheel will lock shortly after you have parked your vehicle and the passive key is outside it or when you lock your vehicle.
Note:   The steering wheel will not lock when the ignition is on or when your vehicle is moving.
Unlocking the Steering Wheel
The steering wheel unlocks when the system detects a valid passive key inside your vehicle. If the steering wheel relocks, switch the ignition on to unlock it.
Note:   You may have to slightly rotate the steering wheel to assist unlocking it.
