Instruments and Controls 5-33 Head-Up Display (HUD) { WARNING If the HUD image is too bright or too high in your field of view, it may take you more time to see things you need to see when it is dark outside. Be sure to keep the HUD image dim and placed low in your field of view. For vehicles with the Head-Up Display (HUD), some information concerning the operation of the vehicle is projected onto the windshield. This includes the speedometer reading, RPM reading, transmission position, outside air temperature, the tap shift gear, and a brief display of the current radio station, including XM information or CD track. It will also display turn-by-turn navigation information if the vehicle has a navigation radio. The images are projected by the HUD lens located on the driver's side of the instrument panel. The tap shift gear will also appear on the HUD if the vehicle has tap shift and it is active. The HUD information can be displayed in one of three languages, English, French, or Spanish. The speedometer reading and other numerical values can be displayed in either English or metric units. The language selection and the units of measurement are changed through the trip computer in the Driver Information Center (DIC). See Vehicle Personalization (With DIC Buttons) on page 5‑47. HUD Display on the Vehicle Windshield The HUD information appears as an image focused out toward the front of the vehicle. When the ignition key is turned to ON/RUN, the HUD will display an introductory message for a short time, until the HUD is ready.
