158 UNDERSTANDING YOUR INSTRUMENT PANEL "Display Units of Measure in" The EVIC, odometer, and navigation system (if equipped) can be changed between English and Metric units of measure. To make your selection, press and release the FUNCTION SELECT button until "US" or "METRIC" appears. "Headlights On With Wipers" (Available with Auto Headlights Only) When ON is selected, and the headlight switch is in the AUTO position, the headlights will turn on approximately 10 seconds after the wipers are turned on. The headlights will also turn off when the wipers are turned off if they were turned on by this feature. To make your selection, press and release the FUNCTION SELECT button until "ON" or "OFF" appears. NOTE: Turning the headlights on during the daytime causes the instrument panel lights to dim. To increase the brightness, refer to "Lights" in this section. RADIO GENERAL INFORMATION Radio Broadcast Signals Your new radio will provide excellent reception under most operating conditions. Like any system, however, car radios have performance limitations, due to mobile operation and natural phenomena, which might lead you to believe your sound system is malfunctioning. To help you understand and save you concern about these "apparent" malfunctions, you must understand a point or two about the transmission and reception of radio signals. Two Types of Signals There are two basic types of radio signals...AM or Amplitude Modulation, in which the transmitted sound causes the amplitude, or height, of the radio waves to vary...and FM or Frequency Modulation, in which the frequency of the wave is varied to carry the sound.
