Multipath distortion
FM signals are typically "line-of-sight" and very reflective. Their reflectivity to objects such as
buildings, mountains or even other passing vehicles causes the condition known as multipath distortion.
This distortion is the result of the reflected signal and the direct signal reaching your antenna at slightly
different times causing a cancellation of all signals. This condition will sound like hissing or static. Very
little can be done to eliminate this problem, however, lowering the treble on your radio could help mask
these disturbances thereby allowing you to achieve optimum pleasure from your audio system.

Your Volvo is equipped with a heating system combined with air conditioning.
Depending on which function you select, warm of cool/cold air is distributed to the different parts of the
passenger compartment. An additional driver's air louver is located beneath the steering column and can
be adjusted upwards, downwards, or closed as desired.
