Flashing one time: Any door, the rear gate or the trunk lid has been opened. Flashing three times: The impact sensor in the system's unit has been activated. This may indicate that your vehicle has been shocked or tampered with by some outside force and/or unauthorized person. Flashing four times: The ignition switch has been turned on. To exit this mode, close the door and turn the ignition switch to the "ON" position. - CONTINUED - 2-19
