Manual Temperature Control (MTC) - Dual Zone

The dual zone manual temperature control (MTC) heating-A/C system allows completely independent side-to-side temperature control of the discharge air.

MTC Dual Zone Front A/C-Heater Control:

The MTC A/C-heater control is located in the instrument panel and contains:
- a power on/off switch. Contains an LED that illuminates to indicate when the heating-A/C system is On.
- a rear window defogger on/off switch. Contains an LED that illuminates to indicate when the EBL system is On.
- slide controls for completely independent side-to-side temperature control of the discharged air. The full range of temperature that the heating-A/C system can produce in any mode is available on either side of the vehicle by independently positioning the slide controls on the instrument panel.
- an air recirculation on/off switch. Contains an LED that illuminates to indicate when the heating-A/C system is in the Recirculation mode.
- an air conditioning on/off switch. Contains an LED that illuminates to indicate when the heating-A/C system is in the A/C mode.
- a rotary control to manually select the air delivery mode.
- a rotary control to manually select the blower fan speed.

- The two slide controls enable continuously variable proportioning of the conditioned air.
- The mode control knob enables continuously variable proportioning of air flow between modes and has detents adjacent to each icon.
- The blower control provides four separate speeds and an Off position.
- When the heater-A/C system is off, the HVAC computer closes the recirculation door to prevent outside air from entering the passenger compartment.
- Interior air may be recirculated to speed up heating or cooling in all modes except defrost and mix by pressing the Recirculate button on the A/C-heater control.
- To reduce humidity for rapid defogging, the A/C compressor runs automatically in modes from "mix" to full defrost when outside temperatures are above freezing.
- Air conditioning is available in any mode by pressing the snowflake, A/C on/off button.
