If your vehicle is a 4 door
model, it is equipped with
rear door security locks that
help prevent passengers
from opening the rear doors
from the inside.
The rear doors of your vehicle cannot be opened from
the inside when this feature is in use. If you want
to open a rear door when the security lock is on,
do the following:
1. Unlock the door from the inside.
2. Then open the door from the outside.
If you don't cancel the security lock feature, adults or
older children who ride in the rear won't be able to open
the rear door from the inside. You should let adults and
older children know how these security locks work,
and how to cancel the locks.
To cancel a rear door lock, do the following:
1. Unlock the door from the inside and open it from
the outside.
2. Move the switch down.
3. Do the same to the other rear door.
The rear doors will now work normally.
