Refuel Control
The unit judges that the driver is refueling the vehicle and accelerates the fuel gauge segment movement if the
fuel level changes by 15 (4 US gal, 3 - 1/4 lmp gal) or more.
AMBIENT TEMPERATURE
The combination meter calculates ambient temperature based on the following signals, and the calculated
value is displayed on the information display.
NOTE:
• The indicated temperature is corrected based on an ignition signal, ambient temperature detected by the
ambient sensor, and vehicle speed signal. The indicated temperature is not raised under vehicle speed less
than 20 km/h (12 MPH).
• The ambient sensor input value that is displayed on “Data Monitor” of CONSULT is the value before the cor-
rection. It may not match the indicated temperature on the information display.
• Depending on engine heat or heat on the road surfaces, an ambient temperature may be indicated higher
than actual one.
TRIP COMPUTER
Current Fuel Consumption
The combination meter calculates current fuel consumption based on the following signals, and the calculated
value is displayed on the information display.
NOTE:
• Current fuel consumption on the information display is updated approximately every 0.5 seconds.
• Current fuel consumption on the information display shows 0 l/100km (0 mpg) when vehicle speed is 0 km/h
(0 MPH).
