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

Unit

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

Refer to 

MWI-37, "Description"

. 

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.
