Head-Up Display (HUD) {CAUTION: 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. If the vehicle has 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 DIC Vehicle Customization (With DIC Buttons) on page 255. 190
