Mazda CX-3: Appendix / Radio Reception

Mazda CX-3 (2015-2024) Owner's Manual / Interior Features / Appendix / Radio Reception

AM characteristics

AM signals bend around such things as buildings or mountains and bounce off the ionosphere.

Therefore, they can reach longer distances than FM signals.

Because of this, 2 stations may sometimes be picked up on the same frequency at the same time.

FM characteristics

An FM broadcast range is usually about 40―50 km (25―30 miles) from the source. Because of extra coding needed to break the sound into 2 channels, stereo FM

has even less range than monaural (non-stereo) FM.

Mazda CX-3. Radio Reception

Signals from an FM transmitter are similar to beams of light because they do not bend around corners, but they do reflect. Unlike AM signals, FM signals cannot travel beyond the horizon. Therefore, FM stations cannot be received at the great distances possible with AM reception.

Atmospheric conditions can also affect FM reception. High humidity will cause poor reception. However, cloudy days may provide better reception than clear days.

Multipath noise

Since FM signals can be reflected by obstructions, it is possible to receive both the direct signal and the reflected signal at the same time. This causes a slight delay in reception and may be heard as a broken sound or a distortion. This problem may also be encountered when in close proximity to the transmitter.

Flutter/Skip noise

Signals from an FM transmitter move in straight lines and become weak in valleys between tall buildings, mountains, and other obstacles. When a vehicle passes through such an area, the reception conditions may change suddenly, resulting in annoying noise.

Weak signal noise

In suburban areas, broadcast signals become weak because of distance from the transmitter. Reception in such fringe areas is characterized by sound breakup.

Strong signal noise

This occurs very close to a transmitter tower. The broadcast signals are extremely strong, so the result is noise and sound breakup at the radio receiver.

Station drift noise

When a vehicle reaches the area of 2 strong stations broadcasting at similar frequencies, the original station may be temporarily lost and the second station picked up. At this time there will be some noise from this disturbance.

    The AUTOHOLD function automatically holds the vehicle stopped, even if you take your foot off the brake pedal. This function can be best used while stopped in traffic or at a traffic light. The brakes are released when you resume driving the vehicle such as by releasing the clutch pedal with the shift lever shifted to a position other than the neutral position (manual transaxle vehicle) or depressing the accelerator pedal (automatic transaxle vehicle)...

    Fuel Gauge

    The fuel gauge shows approximately how much fuel is remaining in the tank when the ignition is switched ON. We recommend keeping the tank over 1/4 full.

    Mazda CX-3. Fuel Gauge

    If the low fuel warning light illuminates or the fuel level is very low, refuel as soon as possible.

    If inconsistency in engine performance or stalling occurs due to low fuel level conditions, refuel the vehicle as soon as possible and add at least 10 L (2.7 US gal, 2.2 Imp gal) of fuel. Refer to Taking Action.
