When leaving the vehicle, always take the SmartKey with you and lock the vehicle. The engine can be started by anyone with a valid SmartKey that is left inside the vehicle.

  • To activate with the SmartKey: remove the SmartKey from the ignition lock.
  • To activate with KEYLESS-GO: switch the ignition off and open the driver's door.
  • To deactivate: switch on the ignition.
