DESCRIPTION
• The information display is an LCD positioned inside the combination meter. It is used to inform the driver of a
variety of vehicle information.
• The combination meter receives the signals required to control the operation of the information display from
each unit, switch, and sensor.
• Based on the received signals, the combination meter displays the following information on the information
display:
- Odo/trip meter
- Shift indicator
- Trip computer
- Interrupt indication
- Warning check indication
- Setting
- Timer status remained display
- Charging time display
- Meter illumination control
- ASCD status display
• The information display screen is divided into sections (A) – (C),
and the items displayed in each section are different.

ASCD STATUS DISPLAY
Based on the signals listed below, the combination meter displays the ASCD status.
For details, refer to
EVC-64, "AUTOMATIC SPEED CONTROL DEVICE (ASCD) : System Description"
.
TRIP COMPUTER
Based on the signals received from each unit, switch, and sensor, the combination meter displays the items
shown below:
• Current electricity consumption
• Average electricity consumption
• Average vehicle speed
• Travel distance
• Travel time
Current Electricity Consumption
The combination meter calculates current electricity consumption based on the following signals, and the cal-
culated value is displayed on the information display:
NOTE:
• Current electricity consumption on the information display is updated approximately every 0.5 seconds.
• Current electricity consumption on the information display shows 0 kWh/miles (0 kWh/km) when vehicle
speed is 0 MPH (0 km/h).

NOTE:
Average electricity consumption on the information display is updated approximately every 30 seconds.
Average Vehicle Speed
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 power switch is turned READY right after battery removal and installation, “
−
−−” is displayed until after a 30 seconds.
Travel Distance
The combination meter calculates mileage, based on the following signals and displays the mileage on the
information display:
Travel Time
The combination meter measures and displays travel time (power switch ON time).
CHARGING TIME DISPLAY
Based on the signals below, the combination meter displays the charge time.
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.
