General Description
The circuit consists of the starter switch, seat heater
switch and the heat unit.
The seat heater is provided in driver’s and front
passenger seats (as option).
When the seat heater switch is ON, the seat heat built in
the seat back and cushion is switched on to warm the
seats.
To prevent the seats from being overheated, the circuit is
fitted with a thermostat.

Power Door Mirror System
General Description
The circuit consists of the starter switch, door mirror
control switch, folding switch, defogger switch and door
mirrors on both sides.
The door mirror switch consists of the control switch,
folding switch and defogger switch.
When the control switch is operated with the starter
switch at either “ACC” or “ON” position, the motors
incorporated in the door mirrors on both sides rotates to
allow the horizontal and vertical adjustment of mirror
angles.
The folding switch can be used to fold the mirror and
return it to its original position.
When turning on the door mirror defogger switch with the
starter switch at “ON” position, built-in heater in the mirror
is activated to perform the defogger function.

Power Door Mirror
General Description
Mirrors contain two driving motors for the horizontal and
vertical movement of the mirror and one motor for folding
the mirror.
The movement of the mirror is controlled by the direction
of current running through these motors.
The housing portion of the mirror is provided with the
auto-stop mechanism which is interlocked with the motor
for folding the mirror. When the mirror moves to the stop
position (with the mirror folded or returned to its original
position), the current to the motor is shut off.
When the mirror cannot operate due to some obstacle
and the motor stops its rotation, the resistor prevents
current overflow.
