Hyundai Santa Fe (TM): Door locks / 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 should 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 will not open if the inner door handle is pulled.
To lock the child safety lock, insert a small flat blade tool (like a 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
If children accidently open the rear doors while the vehicle is in motion, they could fall out of the vehicle. The rear door safety locks should always be used whenever children are in the vehicle.
Your vehicle is equipped with features that will automatically lock or unlock your vehicle based on settings you select in the infotainment system screen.
When the electronic child safety lock button is pressed and the indicator light on the button illuminates, the rear doors cannot be opened from inside the vehicle.
