Important information on using our HEOSafe® door locks: 1. Make sure that the HEOSafe® door lock latch is not activated by children playing or accidentally when a door is open. Otherwise, the latch will hit the frame or locking bolt when closing, which could cause damage. 2. Make sure that children or people with disabilities do not lock themselves in while alone in the vehicle. If this happens, leave another door (driver's cab door, rear door) open for safety. 3. When you are in the vehicle, the escape doors must not be additionally secured with HEOSafe® from the outside, because external locks cannot be opened from the inside. 4. Before opening the sliding door, always check that the key has been removed from the HEOSafe® lock, as otherwise it could break off! 5. While driving, you should not lock the HEOSafe® door locks to allow emergency services access to the vehicle in the event of an accident.
