Auto Door Lock/Unlock Features
Impact sensing door unlock system
All doors are automatically unlocked when an impact causes the airbags to deploy.
Child-protector Rear Door Locks
The child safety lock is provided to help prevent children seated in the rear from accidentally opening the rear doors.
The rear door safety locks must be used whenever children are in the vehicle. The child safety lock is located on the edge of each rear door. When the child safety lock is in the lock position, the rear door does not open if the inner door handle is pulled.
To lock the child safety lock, insert a small flat blade tool (e.g. screwdriver or similar) 1 into the slot and turn it to the lock position as shown.
To allow a rear door to be opened from inside the vehicle, unlock the child safety lock.
WARNING
Never allow children to open the rear doors while the vehicle is moving. They may fall out of the vehicle. Be sure to use the rear door safety locks whenever children are in the vehicle.
