DRIVE COMPUTER
Refer to Owner′s Manual for drive computer operating instructions.
TRIP Switch
When “TRIP” switch is pressed, display TRIP screen. As TRIP infor-
mation, it indicates journey time (TIME), trip odometer (DIST), aver-
age vehicle speed (AVG).
Pressing “TRIP” switch once cycles display from TRIP 1 →TRIP
2 → Display OFF →TRIP 1.
“TIME”

Journey time indication is performed by reset or battery connec-
tion.

When pushing “TRIP RESET” or “TRIP” switch more than
approximately 1.5 seconds, journey time will be reset.

If journey time is reset, journey distance and average speed will
be reset at the same time.
“DIST”

Trip odometer indication is performed by vehicle speed signal.

When pushing “TRIP RESET” or “TRIP” switch more than approximately 1.5 seconds, driving distance will
be reset.

If trip odometer is reset, journey time and average speed will be reset at the same time.
“AVG”

Average speed indication is performed by running distance and running time.

Indication will be renewed every 30 seconds.

When pushing “TRIP RESET” or “TRIP” switch more than approximately 1.5 seconds, average speed will
be reset.

After reset operation, the displays shows “ ” for 30 seconds.
FUEL ECON Switch
When “FUEL ECON” switch is pressed, display FUEL ECON screen.
As FUEL ECON information, it indicates average fuel consumption
(AVG), distance to empty (DTE).
Pressing “FUEL ECON” switch once cycles display from FUEL
ECON →Display OFF →FUEL ECON.
“AVG” (Average Fuel Consumption)

Average fuel consumption indication is performed by fuel con-
sumption signal and vehicle speed signal after system is reset.

Indication will be renewed every 30 seconds.

When pushing “TRIP RESET” or “FUEL ECON” switch more
than approximately 1.5 seconds, average fuel economy will be
reset.

After reset operation, the display shows “ . ” until the vehicle is driven 500 m (1,600 ft.) or 30 seconds
has passed.
“DTE” (Distance to Empty)

Distance to empty receives via CAN communication and indicates values calculated by meter.

Display range is max 999 miles (max 999 km).

If low-fuel WARNING is received from meter via CAN communication, distance to empty indication will be
“”.

Indication will be renewed every 30 seconds.
