Operating the audio system

AM (MW, LW) and FM radio signals are transmitted from broadcast towers located in the surrounding area. They are picked up by the vehicle's antenna. The signal is then received by the audio system and sent to the speakers.

When a strong radio signal reaches the vehicle, the audio system technology ensures the best possible sound quality. However, in some cases the signal reaching the vehicle may not be strong and clear.

This may be due to factors such as distance from the radio station, proximity to other stations, or the presence of buildings, bridges or other large obstacles in the area.

AM (MW, LW) broadcasts can be received at greater distances than FM broadcasts. This is because AM (MW, LW) radio waves are transmitted at lower frequencies. These long, low-frequency radio waves can follow the curvature of the Earth instead of traveling in a straight line through the atmosphere. In addition, they bend around obstacles, providing better signal coverage.

FM broadcasts are transmitted at higher frequencies and do not bend to follow the surface of the Earth. For this reason, FM broadcasts weaken over a short distance from the station. FM signals are also easily blocked by buildings, mountains or other obstacles.

All of this can lead to certain listening conditions that may make it seem as if the audio system has a problem.

The following conditions are normal and do not indicate a radio malfunction:

- Fading: as the vehicle moves away from the radio station, the signal weakens and the sound begins to fade out.

In this case, select a station that can be heard more clearly.

- Static/interference: weak FM signals or large obstacles between the transmitter and the radio may disturb the signal, causing static noise or interference. Reducing the treble level may reduce this effect until the noise disappears.

- Station switching: when the FM signal weakens, a stronger signal from a nearby frequency may take over. This happens because the radio is designed to lock onto the clearest signal. In this case, select a station with a stronger signal.

- Multipath cancellation: radio signals received from multiple directions can cause distortion or interference. This may be caused by a signal reflected from the same station or by signals from two stations on nearby frequencies. If this occurs, select another station until the condition changes.

Using a mobile phone or two-way radio

When a mobile phone is used in the vehicle, the audio system may produce noise.

This does not indicate a system problem.

In this case, use the mobile phone at a location as far away from the audio system as possible.

NOTICE When using a communication system such as a mobile phone or two-way radio inside the vehicle, a dedicated external antenna must be installed. Using mobile phones or two-way radios that rely on their own antenna inside the vehicle may interfere with the vehicle's electrical system and compromise the operation of safety systems. WARNING Do not use a mobile phone while driving. You must stop in a safe place to use a mobile phone.
