KEYS AND DOORS
CAUTION
Before driving, make sure the doors are closed and locked,
especially when small children are in the vehicle. Along with
the proper use of seat belts, locking the doors helps prevent the
driver and passengers from being thrown out from the vehicle
during an accident. It also helps prevent the doors from being
opened unintentionally.
