The HUD controls are located in the overhead console. To turn the HUD display off, slide the dimmer control all the way down. If the sun comes out, the sky becomes cloudy, or if you turn your headlamps on, you may need to adjust the HUD brightness using the dimmer control. Polarized sunglasses could make the HUD image harder to see. To change the display from English to metric units, push the ENG/MET button located to the left of the steering column. 1. Start your engine and slide the HUD dimmer control all the way up. The brightness of the HUD image is determined by whether the headlamps are on or off, and where you have the HUD dimmer control set. 2. Adjust the seat to your driving position. Slide the image height adjuster control all the way up, raising the image as far as possible. 3. Now slide the image height adjuster control down so the image is as low as possible but still in full view. 4. Slide the dimmer control downward until the HUD image is no brighter than necessary. Care of the HUD Clean the inside of the windshield as necessary to remove any dirt or film that reduces the sharpness or clarity of the HUD image. To clean the HUD lens, spray household glass cleaner on a soft, clean cloth. Gently wipe and dry the HUD lens. Do not spray cleaner directly on the lens to avoid cleaner leaking inside the unit. 2-98
