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 it as such, you may misjudge the distance and damage your vehicle. The HUD controls are located to the left of the steering wheel on the instrument panel. To adjust the HUD so you can see it properly: When the HUD is on, the speedometer reading will always be displayed. The current radio station, cassette tape or CD number and track number will only be displayed for three seconds after the radio, tape or CD track status changes. This will happen whenever one of the radio controls is pressed, either on the radio or on the audio steering wheel controls (if equipped). 1. Start your engine and turn the dimmer knob to the desired HUD image brightness. The brightness of the HUD image is determined by the ambient light conditions in the direction your vehicle is facing and where you have the HUD dimmer knob set. If you are facing a dark object or a heavily shaded area, your HUD may anticipate that you are entering a dark area and may begin to dim. 2. Adjust the driver's seat. If you change your seat position, you may have to readjust your HUD. 3. Press the UP or DN buttons until the HUD image is easy to see and then press the DN button until the HUD image is as low as possible, but remains in full view straight ahead near the front bumper. The HUD image can only be adjusted up and down, not side-to-side. 4. To turn the image off, turn the dimmer knob counterclockwise to OFF. 3-20
