120 UNDERSTANDING YOUR INSTRUMENT PANEL NOTE: If you experience difficulty in playing a particular disc, it may be damaged, oversized, or have theft protection encoding. Try a known good disc before considering disc player service. You may have a problem with CD-R (recordable) and CD-RW (recordable and writable) disks. RADIO OPERATION AND CELLULAR PHONES Under certain conditions, the operation of a cellular phone in your vehicle can cause erratic or noisy performance from your radio. This condition may be lessened or eliminated by relocating the cellular phone antenna. This condition is not harmful to the radio. If your radio performance does not satisfactorily "clear" by the repositioning of the cellular antenna, it is recommended that the radio volume be turned down or off during cellular phone operation. CLIMATE CONTROLS Manual Air Conditioning/Heater Control The Air Conditioning System allows you to balance the temperature, amount, and direction of air circulating throughout the vehicle. The air conditioning system of your vehicle contains R-134a, a refrigerant that does not deplete the ozone layer in the upper atmosphere.
