Push button start system

Your vehicle is equipped with the push button start system. You can start your vehicle by pressing the start button in combination with the brake pedal rather than using a key.
The start button is located on the instrument panel to the right of the steering wheel.
In order to operate the push button start system and start the vehicle, your Intelligent Access key (IA key) must be present inside the vehicle.
