Description And Operation: Overview

The Instrument Cluster (IC) is a high definition TFT (thin film transistor) display.

The display is continually reconfigured to prioritize and refine the information presented to the driver. All displays are 'virtual' with the speedometer and the tachometer/HEV power gauge being the dominant features of the display.

Hybrid Electric Vehicles (HEV) have a Power gauge which replaces the tachometer when the cluster is in "full hybrid display" or when the vehicle is in driver selected 'EV' mode. This gauge is used to display the status of the HEV system.

Two hardwired warning indicators are in the cluster; the security warning indicator and a primary airbag/SRS (supplemental restraint system) warning indicator. These warning indicators are LED (light emitting diode) 's. All other warning indicators are generated within the IC TFT screen.

Two ambient light sensors; one on either side of the instrument cluster, (to ensure the brightest lighting conditions are detected) are used to adjust cluster illumination in response to prevailing lighting conditions.

The IC features a number of warning indicators. The warning indicators illuminate in one of four colors which indicate the level of importance of the warning as follows:

• Red = Warning.
• Amber = Caution.
• Green = System operative.
• Blue = Headlamp high beam operative.

A feature and driver preference menu is available to allow the driver to select certain features and functions of the IC and change them to their personal preference. A menu control 'joy pad' is located on the left steering wheel switchpack and allows selection of the displayed functions and navigation of the menus. When selected, the menu is displayed in the TFT screen which allows access to a number of vehicle functions.

Hybrid Electric Vehicles (HEV) have an additional display which replaces the tachometer when required to show the status of the HEV systems.
