When the HUD is on, the speedometer reading will always be displayed. The current audio system information 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. Under warning conditions, the CHECK GAGES message will illuminate in the HUD. Look at the instrument panel cluster for more information. Notice: If you try to use the HUD image as a parking aid, you may misjudge the distance and damage your vehicle. Do not use the HUD image as a parking aid. 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, do the following: 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. 3-22
