FUNCTION
The trip computer can indicate the following items.
• DTE (distance to empty)
• Trip distance
• Trip time
• Average fuel consumption
• Average vehicle speed
DTE (DISTANCE TO EMPTY) INDICATION
The range indication provides the driver with an estimation of the distance that can be driven before refueling.
The range is calculated by signals from the fuel level sensor unit (fuel remaining), ECM (fuel consumption)
and the ABS actuator and electric unit (vehicle speed). The indication will be refreshed every 30 seconds.
When fuel remaining is less than approximately 11.6 (3 1/8 US gal, 2 1/2 Imp gal), the indication will blink as
a warning. If the fuel remaining is less than approximately 9.6 (2 1/2 US gal, 2 1/8 Imp gal), the indication will

Description
Combination meter
Turns the oil pressure warning lamp ON/OFF according to the oil pressure switch signal received
from BCM by means of communication.
IPDM E/R
Reads the ON/OFF signals from the oil pressure switch and transmits the oil pressure switch signal
to the combination meter via BCM with the CAN communication line.
Oil pressure switch

BCM
Transmits the oil pressure switch signal received from IPDM E/R via CAN communication to the
combination meter via CAN communication.

show “---”. In this case, the display will change to the DTE mode even though the display is showing a different
mode. When the battery is disconnected and reconnected, DTE mode will display “---” until the vehicle is
driven 0.3 miles (0.5 km).
TRIP DISTANCE
Trip distance is calculated by signal from the ABS actuator and electric unit (vehicle speed). If trip distance is
reset, trip time will be reset at the same time.
TRIP TIME
Trip time displays cumulative ignition switch ON time. If trip time is reset, trip distance will be reset at the same
time.
AVERAGE FUEL CONSUMPTION
Average fuel consumption indication is calculated by signals from the ABS actuator and electric unit (vehicle
speed) and the ECM (fuel consumption). The indication will be refreshed every 30 seconds.
AVERAGE VEHICLE SPEED
Average vehicle speed indication is calculated by running distance and running time. The indication will be
refreshed every 30 seconds. If average vehicle speed is reset, average fuel consumption will be reset at the
same time. After resetting, the display will show “---” for 30 seconds.
HOW TO CHANGE/RESET INDICATION
Refer to Owner's Manual for trip computer operating instructions.

DESCRIPTION
With the ignition switch in the ON position, and the mode or (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 calibrated using the following procedure.
