Choosing the coldest or warmest temperature setting will not cause the system to heat or cool any faster. If you set the system at the warmest temperature setting, the system will remain in manual mode at that temperature and it will not go into automatic mode. In cold weather, the system will start at reduced fan speeds to avoid blowing cold air into your vehicle until warmer air is available. The system will start out blowing air at the floor but may change modes automatically as the vehicle warms up to maintain the chosen temperature setting. The length of time needed for warm up will depend on the outside temperature and the length of time that has elapsed since your vehicle was last driven. 3. Wait for the system to regulate. This may take from 10 to 30 minutes. Then adjust the temperature, if necessary. You can switch from English to metric units through the Driver Information Center (DIC). If you have the Base audio system, see DIC Main Menu on page 3-62. If you have the Navigation system, see "Setup Menu" in the Index of the CTS Navigation System Owner Manual. The air-conditioning system removes moisture from the air, so you may sometimes notice a small amount of water dripping underneath your vehicle while idling or after turning off the engine. This is normal. Do not cover the solar sensor located in the center of the instrument panel, near the windshield. For more information on the solar sensor, see "Sensors" later in this section. Manual Operation yN z (Mode): Pressing the mode switch and changing the mode cancels automatic operation and places the system in manual mode. Press AUTO to return to automatic operation. The outboard air outlets will always receive airflow regardless of the mode selected. See Outlet Adjustment on page 3-32 to change this airflow from the outboard outlets. To change the current mode, select one of the following: Y (Vent): This mode directs air to the instrument panel outlets. This mode directs approximately half of the air to the instrument panel outlets, and then directs most of the remaining air to the floor outlets. Some air may be directed toward the windshield. In automatic operation, cooler air is directed to the upper outlets and warmer air to the floor outlets. \ (Bi-Level): 3-28
