RADIO OPERATION AND CELLULAR PHONES
Under certain conditions, the cellular phone being ON 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
antenna, it is recommended that the radio volume be
turned down or off during cellular phone operation.
CLIMATE CONTROLS
Climate Controls
The Climate Control System allows you to balance the
temperature, amount, and direction of air circulating
throughout the vehicle. The controls are located on the
instrument panel, below the radio.
The air conditioning system of your vehicle contains
R-134a, a refrigerant that does not deplete the ozone layer
in the upper atmosphere.
