Door Locks
CAUTION:
• It is dangerous to leave doors unlocked. Before driving off (especially if children are in the vehicle), make sure all doors are securely closed and locked so they cannot be opened accidentally from the inside. This helps ensure that doors do not open unexpectedly.
Along with the proper use of seat belts, locking the doors helps prevent occupants from being thrown from the vehicle in the event of an accident.
• Always make sure no vehicles are approaching before opening a door.
