The reconfigurable head-up display (HUD) is a secondary display system that optically projects critical vehicle information on the windshield. The head-up display is controlled by a combination switch located in the vehicle center console:
- Page switch: The HUD displays three standard format pages including format 1, format 2, format 3, other temporary navigation information and traction/stability system messages.
- Up/Down Switch: There is an electric tilt adjust indicated by up and down arrows within the center of the HUD switch. Moving this switch directs the motor to move the HUD image up or down on the windshield.
- Power/Dimmer Switch: When the switch is in the "O" position, it is indicating that the HUD is in the OFF position. Once it is turned into the next position the HUD is powered on and now assumes the dim control of the display.
During start up of the vehicle, all segments of the head-up display illuminate for 3 seconds. The HUD display then displays the last known format before being powered down. The formats include the following:
Format 1
| • | Tap Up/ Tap Down/ Upshift |
| • | Outside air temperature |
