Range
Journey distance
Journey time
Average fuel economy
Average vehicle speed
Board computer Display
Range (km or MILES) Displays range to empty with a range of 000.0 to 999.9.
Journey distance (km or MILES) Displays journey distance with a range of 000.0 to 9999
Journey time Displays journey time with a range of 0000:00:00 to 9999:59:59.
Average fuel consumption (/100 km or
MPG)Displays fuel consumption with a range of 00.0 to 999.
Average vehicle speed (km/h or MPH) Displays average vehicle speed with a range of 000 to 999.
RangeNJEL0555S0401The elapsed time indication provides driver with an estimation
of the distance that can be driven before refuelling.The range
is conducted by fuel tank level sensor unit (fuel remaining),
ECM pulse signal (fuel consumption) and vehicle speed signal.
Indication will be renewed every 30 seconds.
When fuel remaining is less than approx. 7.8(6-7/8 Imp qt),
indication will blink as a warning. If the fuel remaining less than
approx. 6.8(6 Imp qt), “– –.–” will be indicated. In this case,
the mode will change to the RANGE mode automatically even
though the display is showing a different item. (See NOTE.)
The range mode includes a low range warning feature: when
the fuel level is low, the range mode is automatically selected
and the digits blink in order to draw the driver′s attention. Press
the “INFO” switch if you wish to return to the mode that was
selected before the warning occurred. The range mark will
remain blinking until next refuelling. When the fuel level drops
even lower, the range display will change to “– – – –”.
Journey DistanceNJEL0555S0402Journey distance indication is conducted by vehicle speed sig-
nal.
If journey distance is reset, journey time will be reset at the
same time.
When pushing “INFO” switch more than approximately 1
second, driving distance will be reset.
Journey TimeNJEL0555S0403Journey time indication is conducted by integration of ignition
ON time.
If journey time is reset, journey distance will be reset at the
same time.
Average Fuel ConsumptionNJEL0555S0404Average fuel consumption indication is conducted by ECM
pulse signal and vehicle speed signal after system is reset.
Indication will be renewed every 30 seconds.
