< SYSTEM DESCRIPTION >
SYSTEM
The LOOSE FUEL CAP message will display in the information display when the fuel-filler cap is not tightened
correctly. The message will turn off as soon as the EC M detects the fuel-filler cap is properly tightened. The
ECM provides a loose fuel cap signal to the combination meter via CAN communication.
LOW TIRE PRESSURE WARNING
This warning appears when the BCM detects low inflati on pressure or a system malfunction. The BCM sends
a signal to the combination meter via CAN communication to illuminate the low tire pressure warning lamp. In
addition, a warning message will be displayed in the vehicle information display.
DOOR OPEN WARNING
This warning appears when the ignition switch is ON and the door is open. The BCM receives a door switch
signal from the door open door switch. The BCM sends t he door switch signal to the combination meter via
CAN communication lines.
TRUNK OPEN WARNING
This warning appears when the ignition switch is ON and the trunk is opened. The BCM receives a trunk lamp
switch signal from the trunk lamp switch. The BCM s ends the trunk lamp switch signal to the combination
meter via CAN communication.
LOW FUEL WARNING
This warning appears when the fuel level in the fuel tank is less than approximately 4 US gal (15 L, 3.3 Imp
gal). A variable resistor signal is supplied to the combi nation meter from the fuel level sensor unit to determine
the amount of fuel in the fuel tank.
LOW WINDSHIELD WASHER FLUID WARNING
When the windshield washer fluid level is low, the was her fluid level switch provides a ground signal to the
combination meter and the warning is displayed. Once fluid is added, the switch opens and the warning is no
longer displayed.
RELEASE PARKING BRAKE WARNING
When the parking brake is applied, the parking brake switch provides a ground signal to the combination
meter. When the vehicle speed is greater than 4 MPH (7 km/h), the message is displayed and the warning
chime sounds.
SHIFT POSITION INDICATOR
Displays the position of the shift selector based on signals received from TCM via CAN communication.
LOW OIL PRESSURE WARNING
The low oil pressure warning appears in the information display when the combination meter receives a low
engine oil pressure signal from the ECM via CAN communication.
WARNING CHECK INDICATION
The combination meter can cause an interrupt on the information display to indicate a warning, based on sig-
nals received from each unit and switch.
Refer to Owner’s Manual for additional information display items.
COMPASS
COMPASS : DescriptionINFOID:0000000009461691

ON, the compass display will indicate the direction the vehicle is
heading.
Vehicle direction is displayed as follows:
• N: north
• E: east
• S: south
•W: west
