The HUD controls are located to the left of the steering wheel on the instrument panel. 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. 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.
