Chapter 4 Light SystemSection 1 Light System IntroductionI. Composition Light system comprises external illumination and signal system and internal illumination system.
The function of the external illumination and signal system is to illuminate the road ahead and send signals
to other vehicles.
The internal illumination system provides internal illumination for driver and passengers.II. Precaution for service1. Precaution when repairing electrical equipments
Disconnect the battery ground cable.
2. Precaution when replacing a headlamp bulb
(1) Before replacing a halogen bulb, turn the headlamp OFF to make it cool.
(2) When installing a new halogen bulb, do not touch the glass part of the bulb with bare hands.
(3) If there is oil stain on the surface of halogen bulb (headlamp and front fog lamp) when the lamps are
turned ON, its service life will be shortened.
(4) Halogen bulbs (headlamp and front fog lamp) have pressurized gas inside and require special handling.
They can explode if dropped to ground. The glass fragments will splash up.
(5) When replacing, make sure to use the bulbs with the same power, same model.
(6) After the bulb is installed, make the lamp holder tight.III. Bulb specificationsRemark: All bulbs are made by Philips Corp..Light System-

2. Area coverage
Scope of AM and FM broadcasting coverage area differs greatly.
Sometimes although AM broadcast may be received clearly, FM
binaural broadcasting cannot be received. Not only listening zone of
FM binaural broadcasting is small, but also static noise or other
cacophony (noise) tends to occur.
3. Receiving problem
Notes:
Besides static noise problem, there is also interference, multiplex
and attenuation. These problems are not caused by electric cacophony,
but the problem of radio wave itself.
(1) Interference
Besides static noise problem, AM broadcast tends to receive
other types of noise, especially at night. This is because ionosphere
reflects AM radio wave at night, these interference electric waves
interfere with signals from the same signal source while entering into
vehicle antenna directly, this kind of noise is called "interference".
(2) Multiplex
Noise caused by radio wave reflected from barrier is called
"multiplex". When radio signal emitted by broadcast antenna is
reflected by high buildings or high mountains, and disturbs directly
received other signals, multiplex phenomenon occurs.
(3) Attenuation
Since its frequency is higher than AM, FM wave is more easily
reflected by high buildings or high mountains. Therefore, FM signal
often disappears gradually, or when vehicle is blocked by barrier, it
cannot receive any signal, such phenomenon is called "attenuation".Audio System -Audio System Description5-38Chapter 5 Audio SystemSection 1 Audio System DescriptionDescription:

compressor, condenser and evaporator etc, it adsorbs heat in the air through circulation of refrigerant, so as to
reduce air temperature in car body and eliminate water vapour in air, to achieve the purpose of temperature drop
and dehumidification. Heating system mainly consists of heat exchanger and heater unit. It utilizes heat of engine
cooling water to heat air via heat exchanger, so as to achieve the purpose of heating. Regulation and control of
temperature, humidity and flow rate of air in car body is realized via heating and refrigeration systems separately
or jointly.
For parameters of refrigerating system, see the table:
