Combination Meter
7-9
COMBINATION METER
The combination meter is an easy-to-read pointer type meter. At the center is a tachometer, on the left side
a speedometer, on the right side a fuel meter, engine coolant thermometer, and indicator lamp. It has a sport
and efficient design to allow the driver to read the meters clearly.
D
The tachometer displays the conditions of the current road using three indicators TARMAC, SNOW,
and GRAVEL. [Refer to GROUP 2-Active Center Differential (Active Control System.)]
D
A water spray indicator which lights up when the water splay switch is set to AUTO has been adopted.
D
The speedometer is an electronic type speedometer which operates by the pulse signal generated
by the speed sensor.
D
A large and clear LCD type odo-tripmeter is provided. The odometer continuously displays values
while the tripmeter adopts a twin-trip (trip A, trip B) function which is switched by a reset button.
(Standard meter)
D
The fuel gauge is provided with a triangular mark indicating the location of the fuel filler door to
show clearly that the fuel filler door is on the left side of the car.

SMART WIRING SYSTEM (SWS)
SWS is a minimal line system which transmits numerous signals using one wiring to control against
increased weight and complication of harnesses which result from the increase in electronic accessories.
Basically the same as the new SPACE RUNNER.
To transmit numerous signals, the ETACS-ECU*, column switch, front ECU, power window main switch
(power window switch of the driver’s seat side) incorporate multi-distribution circuits to carry out
communication between control units.
NOTE
*: ETACS (Electronic Time and Alarm Control System)

COMMUNICATION METHOD
The exclusive signal lines for transmitting the multi-distribution data are connected as follows between
the ETACS-ECU, column switch (incorporated inside the column ECU), front ECU, power window main
switch (incorporated inside the power window ECU) and power window motor assemblies (incorporated
inside the power window motor ECU) for internal communication.
