• Starting: Press the start/stop button to ignite the engine.
• Locking: Touch the sensor on the door handle to lock the car.

1.2. The Convenience Opening and Closing Feature

The convenience opening and closing feature is an extension of the KEYLESS-GO system. It allows you to control the windows and sunroof remotely using the SmartKey. This is especially useful for:

• Ventilating the car: Opening the windows and sunroof slightly on a hot day to let out trapped heat.
• Securing the car: Quickly closing all windows and the sunroof if you forgot to do so before leaving the vehicle.
• Responding to Weather Changes: Quickly closing windows and sunroof when it starts to rain.
