The reconfigurable head up display (HUD) is an active matrix color display system that optically projects critical vehicle information through the windshield. The head up display is controlled by a combination switch located in the vehicle center console:
| • | Image Up/Down Switch--The HUD image adjustment switch allows the driver to vertically adjust the images on the windshield up or down. The HUD image position on the windshield can be personalized for Driver 1, Driver 2 and Unknown. The vertical image position set by the various vehicle drivers is saved and recalled next time they drive the vehicle. Moving this switch directs the motor to move the HUD image up or down on the windshield. |
| • | Power/Dimmer Switch--The brightness of the HUD image can be adjusted by pressing the knob on the center of the DIC control panel in until it pops out and then pull the knob until it is completely extended. Turn the knob clockwise or counter clockwise to increase or decrease the brightness. If the knob is turned all the way to the left, the HUD will turn OFF. On vehicles with adaptive cruise control, if the HUD is turned OFF, the cruise control will be inoperative. |
