Driver/Vehicle Information Display: Description and Operation
ELECTRONIC VEHICLE INFORMATION CENTERDESCRIPTION
The base instrument cluster can be identified by the single TRIP SHAFT button (24) located to the left of the Tachometer (5). The odometer display (7) doubles as the temperature display when selected by toggling through the odometer menu using the TRIP SHAFT button.
The Electronic Vehicle Information Center (EVIC) features a driver-interactive display (23). The display is located in the lower left part of the instrument cluster below the fuel and engine temperature gauges. This system conveniently allows the driver to select a variety of useful information by pressing the STEP button (25) to the right of the EVIC display.
The EVIC displays information related to the following:
- System Status
- Vehicle information warning message displays
- Personal Settings (customer programmable features)
- Compass display
- Outside temperature display
- Trip computer functions
- UConnect(TM) hands-free communication system displays - If Equipped
- Navigation system screens - If Equipped
- Audio mode display
The EVIC system is comprised of several different components. Those components are:
- Instrument Cluster
- EVIC STEP Button
- Ambient Temperature Sensor
- Remote Compass Module (RCM)
- Controller Area Network (CAN) Data Bus
- Local Interface Network (LIN) Data Bus
The EVIC display and STEP button is part of the Instrument Cluster assembly and is not serviced as a separate component. If the display is inoperative the complete Instrument Cluster assembly must be replaced.
OPERATION
The Electronic Vehicle Information Center (EVIC) uses both non-switched and ignition switched sources of battery current so that some of its features remain operational at any time, while others may only operate with the ignition switch in the On position. When the ignition switch is turned to the On position, the EVIC display (23) will return to the last function being displayed before the ignition was turned to the Off position.
The EVIC system is comprised of several different components that communicate over the Controller Area Network (CAN) and Local Interface Network (LIN) Data Buses. If the system is inoperative a scan tool and the appropriate diagnostic information must be used to diagnose the system and related data buses.
The instrument cluster STEP button (25) is used to operate the different functions of the EVIC system. Pressing and releasing the STEP button will scroll through the following displays:
- Compass/Temperature/Audio
- Average Fuel Economy
- Distance to Empty
- Elapsed Time
- Personal Settings
Once a particular system is displayed, short and long presses of the STEP button will move the EVIC through the system menu. Pressing and holding the STEP button once will clear the reset table function currently being displayed. Reset will only occur if a reset table function is currently being displayed. To reset all resettable functions, press and release the STEP button a second time within 3 seconds of resetting the currently displayed function (Reset ALL will be displayed during this 3 second window).
EVIC DISPLAY MODES

COMPASS/TEMPERATURE/AUDIO
Compass heading and outside temperature are displayed at the top of the EVIC display screen. On the lower half of the screen the audio mode is displayed along with the odometer. One of eight compass headings to indicate the direction the vehicle is facing (N, S, E, W, NE, NW, SE, SW) and to select one of 15 compass variance settings. Outside temperature is displayed in °C (degrees Celsius) or °F (degrees Fahrenheit). Audio mode can display any one of 12 radio station preset frequencies, CD disc number, CD track number, tape, and one of 200 Satellite Radio Channels - if equipped.
Regarding the compass, refer to Personal Settings (Customer Programmable Features).
AVERAGE FUEL ECONOMY
Shows the average fuel economy since the last reset. When the fuel economy is reset, the display will read "RESET" or show dashes for two seconds. Then, the history information will be erased, and the averaging will continue from where it was before the reset.
DISTANCE TO EMPTY (DTE)
Shows the estimated distance that can be travelled with the fuel remaining in the tank. This estimated distance is determined by a weighted average of the instantaneous and average fuel economy, according to the current fuel tank level. This is not resettable.
NOTE: Significant changes in driving style or vehicle loading will greatly affect the actual drivable distance of the vehicle, regardless of the DTE displayed value.When the DTE value is less than 30 miles estimated driving distance, the DTE display will change to a text display of (LOW FUEL(. This display will continue until the vehicle runs out of fuel. Adding a significant amount of fuel to the vehicle will turn off the (LOW FUEL( text and a new DTE value will be displayed, based on the current values in the DTE calculation and the current fuel tank level.
ELAPSED TIME
Shows the total elapsed time of travel since the last reset when the ignition switch is in the ACC position. Elapsed time will increment when the ignition switch is in the ON or START position.
