Passenger's Side Temperature Knob The right front passenger can control the temperature of air for both the front passenger and rear seat area. (The passenger's and driver's knob adjust from 60_ F (16_ C) to 90_ F (32_ C) independent of each other. It is suggested, however, that the passenger's setting stay no more than four degrees warmer or cooler in temperature from the driver's setting.) To turn the system on, press the passenger's side TEMP knob. Turn the passenger's side TEMP knob clockwise to increase the temperature and counterclockwise to decrease the temperature. Press the passenger's side TEMP knob again to turn off the passenger's side system. If the passenger's side is turned off, the driver's side will control the temperature of the entire vehicle. Automatic Operation When the system is set for automatic operation, sensors will control the air delivery mode. Air will come from the floor, the instrument panel or windshield outlets. The fan speed will vary as the system maintains the selected temperature setting. Be careful not to put anything over the electronic solar sensors located near the ends of the instrument panel near the windshield. These sensors are used by the automatic system to regulate temperature. To find your comfort zone, start with the 75_F (24_C) setting and allow about 30 minutes for the system to regulate. Turn the TEMP knob to adjust the temperature if necessary. If you choose 60_F (16_C), the system will remain at that maximum cooling setting and will not regulate fan speed. If you choose 90_F (32_C), the system will remain at that maximum heating setting and will not regulate fan speed. Choosing either maximum setting will not cause the system to heat or cool any faster. With the automatic setting, the air conditioning compressor cycles when needed to cool the air. In cold weather, when the system senses the need for heat, the airflow will be directed out the floor outlets. As the interior temperature approaches a desired setting, the blower speed will decrease. To maintain interior comfort, the airflow may move to the instrument panel air outlets and floor outlets (bi-level mode). On bright sunny days in cold weather, the airflow may come out of the air conditioning outlets (A/C mode) to maintain comfort and prevent stuffiness. 3-3
