INFOID:0000000003776621
INFORMATION DISPLAY : System DescriptionINFOID:0000000003776622
FUNCTION
The information display can indicate the following items.
• Intelligent Key operation information
• Maintenance information
• Warning/Indication messages (Door/liftgate/liftgate glass open, low fuel, low washer fluid, parking brake, A/T
oil temp)
DOOR OPEN WARNING
This warning appears when the ignition switch is ON and the front door LH, front door RH, rear door LH, rear
door RH, back door or glass hatch is opened. The BCM receives a door switch signal from the front door
switch LH, front door switch RH, rear door switch LH, rear door switch RH, back door latch and glass hatch
ajar switch. The BCM sends the door switch signal to the combination meter via CAN communication lines.
Then, when the ignition switch is turned ON, the warning message is displayed.
LOW FUEL WARNING
This warning appears when the fuel level in the fuel tank is less than approximately 11.4 (3 US gal, 2.5 Imp
gal). A variable resistor signal is supplied to the combination meter from the fuel level sensor unit to determine
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).
Once fluid is added, the message will stay on for 30 seconds and then turn off.
PARKING BRAKE INDICATOR
When the parking brake is applied, the parking brake switch provides a ground signal to the combination
meter (unified meter control unit). Then, when the igni tion switch is turned ON and vehicle speed is greater
than 7 km/h (4 MPH), the message is displayed.
Refer to Owner’s Manual for additional information display items.

COMPASS
COMPASS
Description (Early Production)INFOID:0000000004244472
DESCRIPTION
With the ignition switch in the ON position, and the mode (N) switch
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
ZONE VARIATION SETTING PROCEDURE
The difference between magnetic north and geographical north can sometimes be great enough to cause
false compass readings. This difference is known as variance. In order for the compass to operate properly
(accurately) in a particular zone, the zone variation must be calibra ted using the following procedure.
Zone Variation Chart
1. Determine your location on the zone map.
2. Turn the ignition switch to the ON position.
3. Press and hold the mode (N) switch for about 8 sec onds. The current zone number will appear in the dis-
play.
4. Press the mode (N) switch repeatedly until the desired zone number appears in the display.
Once the desired zone number is displayed, stop pre ssing the mode (N) switch and the display will show a
compass direction after a few seconds.
NOTE:
Use zone number 5 for Hawaii.

The compass display is equipped with an automatic correc tion function. If the compass display reads “CAL” or
the direction is not shown correctly, perform the correction procedure below.
1. Press and hold the mode (N) switch for about 10 seconds. The display will read “CAL”.
2. Drive the vehicle slowly in a circle, in an open, safe place. The initial calibration is completed in about 1.5 turns.
NOTE:
In places where the terrestrial m agnetism is extremely disturbed, the
initial correction may start automatically.
