Is so designed, in order to ensure that under any circumstances can be opened from the inside out the door (such as the accident after the wading off), the public was so designed, if you do not want to open from the inside, the child lock is it.
Landlord, he is outside the defense, many cars are like this, you can lock the child. This is not open
After the door lock, the first sliding door switch, the door will not open, pull the second door will open. The back door has a child lock, you can put it in the door of the switch pull, which can not open the inside. Mainly afraid of the accident, the circuit cut off, the staff can not escape from the car, so the front door can be opened (but to pull twice); back door is designed to the child's security lock. Thank you!
