2. Adjust the seat, if necessary, before setting the height control. Press and hold the top of the IMAGE (image height) control, raising the HUD image as far as possible. Then press on the bottom of the HUD image height control to move the image down, so the image is as low as possible, but in full view. 3. Turn the dimmer control counterclockwise until the HUD image is no brighter than necessary. To turn the HUD off, rotate the HUD dimmer control all the way counterclockwise. If the sun comes out, or it becomes cloudy, or if you turn on your headlamps, you may need to adjust the HUD brightness using the HUD dimmer control. Polarized sunglasses could make the HUD image harder to see. Clean the inside of the windshield as needed to remove any dirt or film that reduces the sharpness or clarity of the HUD image. Spray household glass cleaner on a soft, clean cloth. Wipe the HUD lens gently, then dry it. Do not spray cleaner directly on the lens, because the cleaner fluid could leak inside the unit. The HUD controls are located to the left of the steering column. 1. Start your engine and turn the HUD dimmer all of the way clockwise. The brightness of the HUD image is determined by ambient light, and where you have set the HUD dimmer control. 2-81
