A6E811801069T02

Outline

•

The microcomputer in the instrument cluster calculates ambient temperature data, distance driven and
specified time data, fuel consumption data, and fuel remaining data according to signal from signal source.

•

Using these data, the microcomputer displays the following in the information display;
— Instant fuel economy
— Average fuel economy
— Distance to empty
— Average vehicle speed

•

The driver information system switch comprises an INFO switch.

Operation
Drive information system switch

•

The drive information system switch comprises an INFO switch.

•

The modes can be charged in a cyclic pattern by pressing the INFO switch.

•

The data displayed at the time can be reset by holding the INFO switch for 1 second or more. Data are
calculated as soon as the INFO switch is released.

Drive information system display

•

The display changes for each mode as shown.

Construction
Instant fuel economy mode

•

Instant fuel economy is calculated from trip distance and fuel consumption in the previous 2 seconds.

•

Instrument fuel economy is updated from every 2 seconds. (the indication only changes when the difference
between the present value and the next value is 0.8 L/100 km (0.8 L/100 mile) or more.)
Calculation
Instant fuel economy (L/100 km or L/100 mile)=

Fuel consumption over 2 seconds (L) / Distance travelled over last 2 seconds (km or mile)

100

•

When fuel is not consumed, for example, when applying an engine brake, <0.0 L/100 km> or <0.0 L/100 mile>
is displayed.

•

When the vehicle speed is in the invalid display range (see the following chart), <----/100 km> or <----/100 mile>
is displayed.

WARNING AND INDICATOR SYSTEM

Average fuel economy mode

•

Average fuel economy is calculated from trip distance and fuel consumption since the time when the battery is
connected or the average fuel economy data is reset.

•

Average fuel economy is updated every 1 minute.
Calculation
Average fuel economy (L/100 km or L/100 mile)=

Cumulative fuel consumption (L) / Cumulative trip distance (km or mile)

100

•

When the cumulative trip distance is 0 km (0 mile) (the vehicle has not traveled since the battery was last
connected or average fuel economy function was last reset), <999.9 L/km> or <999.9 L/100 mile> is displayed.

•

When the INFO switch is pressed for 1 second or more while displaying the average fuel economy, the
cumulative fuel consumption data and cumulative trip distance data are reset.

•

After the data are reset, <---- L/100 km> or <---- L/100 mile> is displayed for 1 minute.

Distance to empty mode

•

Distance to empty is calculated from fuel consumption for last 32 km (32 mile) driven and remaining fuel
amount.

•

Average vehicle speed is updated every 10 seconds.
Calculation
Distance to empty (km or mile)=

Remaining fuel amount

32 (km or mile) / Fuel consumption for last 32 (km or mile) driven

•

<---- km> or <---- mile> is displayed until the vehicle drives 100 km (100 mile) from the time when the battery is
last connected or when the distance to empty is less than 50 km (50 mile).

Average vehicle speed mode

•

Average vehicle speed is calculated from distance driven and specified time

since the time when the battery is

last connected or the average vehicle speed data is last reset.

•

Average vehicle speed is updated every 10 seconds.
Calculation
Average vehicle speed (km/h or mile/h)=

Cumulative distance driven (km or mile) / Cumulative specified time (hour)

•

When the INFO switch is pressed for 1 second or more while displaying the average vehicle speed, the
cumulative distance driven data cumulative specified time data are reset.

•

After the data are reset, <---- km/h> or <---- mile/h> is displayed for 1 minute.

: Specified time is the period of time from when the ignition switch is turned to ON position, to when the

microcomputer starts calculating the average of vehicle speed.

THEFT-DETERRENT SYSTEM

OUTLINE

A6E812050000T01

•

The theft-deterrent system includes sound and light alarms that activate when the bonnet, the trunk lid (4SD) or
liftgate (5HB), or a door is opened by means other than the transmitter. The turn lights flash and the horn and
the theft-deterrent siren sound.

•

When the transmitter unlock button is pressed, the alarms stop.

•

An intruder sensor has been installed in the forward part of the roof (without sliding sunroof) or in the center
part of the roof (with sliding sunroof). The intruder sensor senses movement in the vehicle based on radio
waves, and sends an alert signal to the theft-deterrent control module.

•

A theft-deterrent siren has been installed on the rear, left side of the trunk (4SD) or liftgate (5HB). The theft-
deterent siren includes an internal back-up power supply so that if power from the battery is cut by any means,
the siren will still sound.
