WARNING: This page is about a different variant/trim than selected.
  1. When the vehicle moves below 1.8 mph (3 km/h) and ACC ON or IGN ON, and one or more doors are open, it searches inside the vehicle every 3 seconds, and the warning light flashes if the smart key is not inside the vehicle.
  2. With all doors closed, there are no more warnings if the smart key is retrieved only once.
