2-18 Keys and doors & Shock sensors (dealer option) The shock sensors trigger the alarm system when they sense impacts applied to the vehicle and when any of their electric wires are cut. The alarm system causes the horn to sound and the turn signal lights to flash for a short time when the sensed impact is weak, but it warns of a strong impact or multiple impacts by sounding the horn and flashing the turn signal lights, both lasting approximately 30 seconds. If you desire, your SUBARU dealer can connect them and set them for activation or deactivation. Examples: Vibration from a construction site Vibration in a multistory car park Vibration from trains . You can have the sensitivity of the shock sensors adjusted to your preference by your SUBARU dealer. Child safety locks NOTE . The shock sensors are not always able to sense impacts caused by breaking in, and cannot sense an impact that does not cause vibration (such as breaking the glass using a rescue hammer). . The shock sensors may sense vibration as indicated in the following examples and trigger the alarm system. Select the settings of the alarm system and shock sensors appropriately depending on where you usually park your vehicle. Each rear door has a child safety lock that prevents the doors from being opened even if the inside door handle is pulled. When the child safety lock lever is in the lock position, the door cannot be opened from inside regardless of the position of the inner door handle lock lever. The door can only be opened from the outside. WARNING Always turn the child safety locks to the "LOCK" position when children sit on the rear seat. Serious injury could result if a child accidentally opens the door and falls out.
