Headlamps Suggested This symbol appears with the Headlamps Suggested message. Ice Possible This symbol appears with the Ice Possible message. This message will appear when the amount of available light outside the vehicle is low and the exterior lamp control is off. This message informs the driver that turning on the exterior lamps is recommended even though the DRL are still illuminated and it has become dark enough outside to require the headlamps and/or other exterior lamps. This message will also appear when the windshield wipers have been on for more than six seconds and the exterior lamp control is off or in the parking lamp position. This message appears when the outside temperature is cold enough to create icy road conditions. Left Rear Door Ajar This symbol appears with the Left Rear Door Ajar message. When this message appears on the display, it means that the driver's side rear door was not closed completely. You should make sure that the door is closed completely. 3-68
