To Adjust the HUD so You Can See it Properly: The HUD controls are located to the left of the steering column. 1, Start your engine and slide the DIM (dimmer) control all the way up. The brightness of the HUD image is determined by whether the headlight switch is on or off, and where you have set the HUD dimmer control. 2. Adjust the seat, if necessary, before setting the heightcontrol. control all the way up, raising the image as far as possible. Then slide the HUD image height control downward so the image is as low as possible but in full view. 3. Slide the dimmer control down until the HUD image is no brighter than necessary. To turn the HUD off, slide the dimmer control all the way down. If the sun comes out, or it becomes cloudy, or if you turn on your headlights, you may need to adjust the HUD's brightness using the HUD dimmer control. Polarizing sunglasses could make the HUD image harder to see. I bright, or too high in your \ field of view, it may take you more time to see things you need to see when it's dark outside. Be sure to keep the HUD image dim and placed low in your field of view. Pushing theENGIMET (English/Metric) button will switch the HUD speedometer indicator from English (conventional) to metric units, or back again. 117 I . .
