To change the current mode, select one of the following: D (Vent): Use this mode to direct air to the upper outlets, with a little air directed to the floor outlets. Warning Lights, Gages, and Indicators This part describes the warning lights and gages that may be on your vehicle. The pictures will help you locate them. Warning lights and gages can signal that something is wrong before it becomes serious enough to cause an expensive repair or replacement. Paying attention to your warning lights and gages could also save you or others from injury. Warning lights come on when there may be or is a problem with one of your vehicle's functions. As you will see in the details on the next few pages, some warning lights come on briefly when you start the engine just to let you know they're working. If you are familiar with this section, you should not be alarmed when this happens. Gages can indicate when there may be or is a problem with one of your vehicle's functions. Often gages and warning lights work together to let you know when there's a problem with your vehicle. When one of the warning lights comes on and stays on when you are driving, or when one of the gages shows there may be a problem, check the section that tells you what to do about it. Please follow this manual's advice. Waiting to do repairs can be costly - and even dangerous. So please get to know your warning lights and gages. They're a big help. 3-23 Use this mode to direct most of the air to the floor outlets. 2(Floor): 9 (Fan): Turn the left knob clockwise or counterclockwise to HIGH, MED (Medium) or LOW to increase or decrease the fan speed in the rear-seating area. Turn the knob to OFF to turn off the fan. Temperature Control: To increase or decrease the temperature for the rear of the vehicle, turn the right knob located on the climate-control panel. The air-conditioning system on the main climate-control panel must be turned on to direct cooled air to the rear of the vehicle. If it is not on, then the temperature in the rear of the vehicle will remain at cabin temperature. Be sure to keep the area under the front seats clear of any objects so that the air inside of your vehicle can circulate effectively. For information on how to use the main climate-control system, see Climate Control System on page 3-18. For information on ventilation, see Outlet Adjustment on page 3-20.
