METER SYSTEM
INFORMATION DISPLAY : System Description
INFOID:0000000004204079
FUNCTION
The information display can indicate the following items.
• Outside air temperature
• Trip/fuel consumption readings
• Intelligent Key operation information
• Maintenance information
• Warning/Indication messages (Door ajar, low fuel, low washer fluid, parking brake, cruise control)
OUTSIDE AIR TEMPERATURE INDICATION
The outside air temperature indication is displayed while the ignition switch is in the ON position.
Indication range is between -30 and 55
°C (-22 and 131°F). When outside temperature is less than 3°C (37°F),
display shows ICY. The indicated temperature is not affected by engine heat. It changes only when one of the
following conditions exists.
• When vehicle speed is more than approximately 20 km/h (12 MPH).
• The ignition switch has been turned OFF for more than 3.5 hours.
• When outside air temperature is less than the indicated temperature.
MPG
Average fuel consumption indication is calculated using vehicle speed signals from the ABS actuator and elec-
tric unit (control unit) and fuel consumption information from the ECM.
MPG/MPH
The average speed mode can be selected to display the average fuel consumption and average speed since
last reset. The indications are calculated using vehicle speed signals from the ABS actuator and electric unit
(control unit) and fuel consumption information from the ECM.
RANGE
The range indication provides the driver with an estimation of the distance that can be driven before refueling.
The range is calculated using signals from the fuel level sensor unit (fuel remaining), ECM (fuel consumption)
and vehicle speed signals from the ABS actuator and electric unit (control unit).
DOOR AJAR WARNING
This warning appears when the Intelligent Key is in the vehicle and any door or the trunk is opened.
LOW FUEL WARNING
This warning appears when the fuel level in the fuel tank reaches approximately 12.3 (3 1/4 US gal, 2 3/4
Imp gal). A variable resistor signal is supplied to the combination meter from the fuel level sensor unit to deter-
mine the amount of fuel in the fuel tank.
LOW WINDSHIELD WASHER FLUID WARNING
This warning appears when the windshield washer fluid level is low. When the windshield washer fluid level is
low, the washer level switch provides a ground signal to the combination meter (unified meter control unit).
The message will be displayed after the ignition switch is turned on for 3 minutes. Once fluid is added, the
message will stay on for 30 seconds and then turn off.
PARKING BRAKE INDICATOR
When the ignition switch is in the ON position and the parking brake is applied, the indicator will turn on. When
the parking brake is applied, the parking brake switch provides a ground signal to the combination meter (uni-
fied meter control unit). Then, when the ignition switch is turned ON and vehicle speed is greater than 5 km/h
(3 MPH), the message is displayed.
CRUISE INDICATOR
The cruise indicator message is displayed when the cruise control main switch is turned on. The ECM pro-
vides an ASCD ON signal to the combination meter (unified meter control unit) via CAN communication lines.
CRUISE SET INDICATOR
The cruise set indicator message is displayed when the vehicle speed is controlled by the ASCD system. The
ECM provides an ASCD ON signal to the combination meter (unified meter control unit) via CAN communica-
tion lines.
