Instrument Cluster / Carrier: Description and Operation: Overview

Instrument Cluster

OVERVIEW
The instrument cluster comprises two analogue gages for the speedometer and the tachometer and a 5 inch Thin Film Transistor (TFT) display for driver information.
The analogue gages are electronically driven using vehicle speed information from the ABS (anti-lock brake system) module for the speedometer and engine speed signals from the ECM (engine control module) for the tachometer. The information is passed to the instrument cluster from the modules on the high speed CAN (controller area network) bus.
The speedometer is located on the LH (left-hand) side of the cluster and is available in three market variants:
- Major scale Miles Per Hour (MPH) UK Diesel and Petrol
- Major scale Miles Per Hour (MPH) US Petrol
- Major scale KM/H ROW Diesel and Petrol.
The secondary speedometer is a digital display in the TFT. In most markets, the displayed units shown can be toggled via the "units" option in the Trip computer menu.
The tachometer is located on the RH (right-hand) side of the cluster and is available in two Revolutions Per Minute (RPM) displays: one for petrol models and one for diesel models.
- Petrol models with a maximum engine speed of 8000 RPM
- Diesel models with a maximum engine speed of 6000 RPM.
The TFT screen displays vehicle related information to the driver, for example; engine temperature, fuel level, gear position, Terrain Response mode, cruise control and Hill Descent Control (HDC).
Driver information is also displayed, for example; navigation turn-by-turn information, voice control, trip computer information and basic audio details.
The gauges are illuminated in a pure white color, but change to a red color when Dynamic mode is selected.
The instrument cluster 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 vehicle information and settings menu is available to allow the driver to select certain features and functions of the vehicle, instrument cluster, trip computer and service information and change them to their personal preference. A menu control 'joy pad' is located on the RH (right-hand) side of the steering wheel and allows selection of the displayed functions and navigation of the menus. When selected, the menu is displayed in the TFT screen.
