Control Panel

The switches on the automatic temperature control (ATC) module control panel have the following functions:

• LH and RH Temperature Switches:  Adjusts the nominal temperature settings of the left-hand (LH) and right-hand (RH) sides of the passenger compartment. The switch can rotate through 270°, between full cold and full hot. The switch surrounds are graduated in 2° increments between 16 and 28 °C. Minor detents define 1 °C steps over the range of the switch. Amber light emitting diode (LED)s in the switch surround illuminate to indicate the temperature setting. When maximum cold is selected, the automatic temperature control (ATC) module also automatically sets the air source to recirculated air, blower speed to maximum and distribution to face. When maximum hot is selected, the automatic temperature control (ATC) module also automatically sets the air source to fresh air, blower speed to maximum and distribution to footwell.
• LH and RH Seat Heater Switches:  Activates the heater elements in the seat cushion and seat back at one of two heat levels. The first press of the switch energizes the heater elements at the higher heat setting and illuminates two light emitting diode (LED)s in the switch. A second press of the switch sets the heater elements to the lower heat setting and extinguishes one of the light emitting diode (LED)s. A further press of the switch de-energizes the heater elements and extinguishes the second light emitting diode (LED). The seat heaters remain on until selected off or the ignition is switched off.
• Blower Switch:  For manual adjustment of blower speed. The switch can rotate through 240°, from off to maximum speed. Eight primary detents define the off position and seven blower speeds. Minor detents define small steps between the primary detents. When blower speed is manually adjusted, amber light emitting diode (LED)s in the switch surround illuminate to indicate the selected blower speed. The light emitting diode (LED)s remain off when blower speed is under automatic control.
• Automatic Mode Switch:  Activates the automatic modes for the air conditioning (A/C) system, blower speed and distribution. Separate amber light emitting diode (LED)s in the automatic mode switch illuminate to show when the blower and the distribution are in automatic mode. Manually selecting the blower speed or a distribution switch extinguishes the related light emitting diode (LED).
• Programmed Defrost Switch:  Activates a program that automatically selects: inlet air to fresh air; distribution to screen only; blower to speed 5; rear screen heater on; windshield heater on (where fitted), air conditioning (A/C) system to automatic mode. An amber light emitting diode (LED) in the switch is illuminated while the defrost program is active.
• Windshield Heater Switch:  Energizes the windshield heater for a set time period, until the switch is pressed again or until the engine stops, whichever occurs first. An amber light emitting diode (LED) in the switch is illuminated while the heater is on.
• Rear Window Heater Switch:  Enabled only with the engine running. Pressing the switch energizes the rear window heater for a set time period, until the switch is pressed again or until the engine stops, whichever occurs first. An amber light emitting diode (LED) in the switch is illuminated while the heater is on.
• Off Switch:  Switches off all of the functions controlled by the automatic temperature control (ATC) module (all tell-tale light emitting diode (LED)s are extinguished). The temperature blend door is set to the full cold position (if the air conditioning (A/C) system is in the automatic mode, if the air conditioning (A/C) system is in the economy mode the current door position is retained); the air source is set to recirculation; the current distribution settings are retained; the blower speed is set to zero. Where fitted, the seat heater switches can still be operated without re-activating the automatic temperature control (ATC) module. The automatic temperature control (ATC) module is re-activated, with all functions in the previous operating state, by a second press of the off switch or by pressing the economy switch. The automatic temperature control (ATC) module can also be re-activated, with the associated effect, by the following switches:
  • The automatic mode switch.
  • Any air distribution switch.
  • The blower switch.
  • The programmed defrost switch.
  • The recirculation switch.
• Economy Switch:  Reduces the air conditioning (A/C) compressor output to a minimum displacement condition x 5%, reducing the engine load required to operate the air conditioning (A/C) compressor. An amber light emitting diode (LED) in the switch is illuminated when the economy mode is selected on.
• Recirculation Switch:  For selection of fresh or recirculated air. On models without pollution sensing, an amber light emitting diode (LED) in the switch is illuminated when recirculated air is selected. On models with pollution sensing, the recirculation switch incorporates two amber light emitting diode (LED). The first press of the switch sets the recirculation flaps to automatic mode and illuminates one light emitting diode (LED). A second press of the switch manually selects recirculated air and illuminates the second light emitting diode (LED). A further press of the switch manually selects fresh air and extinguishes the two light emitting diode (LED)s.
• Distribution Switches (Windshield, Face and Footwell):  For manual selection of air distribution in any combination of windshield, face and footwell outlets. Each switch has a light emitting diode (LED) which illuminates when the related distribution mode is selected.
