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. 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. NOTICE: Although the HUD image appears to be near the front of the vehicle, do not use it as a parking aid. The HUD was not designed for that purpose. If you try to use the display as a marker for the front of your vehicle, such as in a parking lot, you may misjudge distance and hit an obstacle or another vehicle. The HUD controls are located in the overhead console. 2-83
