The head-up display (HUD) is a secondary display system that optically projects critical vehicle information off of the windshield. The head-up display (HUD) system has an electric tilt adjust that is controlled by the HUD up/down switch. Moving this switch directs the motor to move the HUD image up or down on the windshield. The HUD is also equipped with automatic dimming which gives the HUD the ability to sense outside light conditions, via a photo-cell and automatically adjusts the brightness levels. The HUD image brightness can be manually adjusted by moving the HUD dim switch. There is an ambient light sensor which allows the HUD image display to adapt to the brightness levels of the environment. During the start up of the vehicle all segments of the head-up display illuminate for 3 seconds.
There are 5 different HUD modes that can be selected by pressing and holding the PAGE button on the HUD switch:
- Speed only
- Speed and gage
- Speed, gage, and tach
- Speed and tach
- Tach only
The HUD displays the following images:
| • | The speedometer reading in either English or metric units. |
| • | The turn signal indicators |
| • | The high beam indicator |
| • | The 1-4 shift indicator |
| • | The check gages indicator |
| • | Either the oil pressure gage, coolant temp gage, or fuel gage. when any of the 3 gage modes are displayed press the PAGE button quickly in order to change between these gages. |
| • | Values in english or metric units |
Speedometer
The HUD receives a signal from the IPC indicating vehicle speed in either English (mph) or metric (km/h) units.
LH Turn Signal and RH Turn Signal Indicator Inputs
The left and right turn indicators are driven by hardware inputs from the exterior lighting system. The signal is active high (12 volts) and inactive when circuit is open. During hazard mode, both the right and left turn signal circuits are active high, causing both the right and left turn signal indicators to illuminate at the same time.
High Beam Indicator Input
The HUD receives a signal from the IPC with the high beam switch input.
1-4 Shift
The HUD receives a signal from the IPC indicating when to shift gears.
CHECK GAGES Inputs
The IPC monitors different inputs and vehicle messages and sends the information to the HUD. When the HUD receives the information, the CHECK GAGES indicator illuminates.
The HUD will illuminate the CHECK GAGES indicator for the following:
| • | Low Oil Pressure |
| • | Coolant Temp Hot |
| • | Low Fuel |
Gages
The HUD receives a signal from IPC for either the oil pressure gage, fuel gage, or the coolant temp gage.
