Failure to do so may result in a door opening and an occupant could be
thrown out of the vehicle, resulting in death or serious injury.
● Ensure that all doors are properly closed.
● Do not pull the inside handle of the doors while driving.
Be especially careful for the driver’s door and front passenger’s door (for

inside lock buttons are in locked position.
● Set the rear door child-protector locks when children are seated in the rear
seats.

Check the surroundings of the vehicle such as whether the vehicle is on an
incline, whether there is enough space for a door to open and whether a
strong wind is blowing. When opening or closing the door, hold the door
handle tightly to prepare for any unpredictable movement.

dows
