CLIMATE CONTROLLED SEAT
Revision: 2007 April2007 M35/M45
CLIMATE CONTROLLED SEATPFP:870U6
Component Parts and Harness Connector LocationNIS0027H
System DescriptionNIS0027I
The climate controlled seat system is controlled by climate controlled seat control unit.
Heating and cooling are possible for a thermal electric device (heat conversion machine).
NOTE:

The climate controlled seat system is downed when the temperature sensor set as the seat cushion and
the seat back's thermal electric device machine detects 20 °C (68 °F)or more of mutual differences of tem-
perature.

In this case, by turning off ignition switch, system down is canceled and it can be reused by turning on
ignition switch again.

The climate controlled seat blower keep low speed for approximately 60 seconds after turning the climate
controlled seat switch.
CAUTION:

The thermal electric device has the character in which, as for an opposite side. one side becomes
high temperature at the time of low temperature.
