The combination meter calculates average vehicle speed based on the following signals, and the calculated
value is displayed on the information display.
NOTE:
• Average vehicle speed on the information display is updated approximately every 30 seconds.
• Soon after a reset or when the ignition switch is turned ON after battery installation, “
−−−
” is displayed for 30
seconds.
Travel Time
The combination meter measures and displays travel time (ignition switch ON time).
Travel Distance
The combination meter calculates mileage, based on the following signals and displays the mileage on the
information display.
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.
INTERRUPT INDICATION
• The combination meter displays an interrupt regarding a warning, alert, and maintenance on the information
display, based on signals received from each unit and switch.
• When conditions are satisfied, the normal screen switches to a warning screen to display an interrupt.
Door Open Warning
• When all the following operating conditions are satisfied, the combination meter displays a door open warn-
ing on the information display by an interrupt.
