11.1 Warning and precaution 

11.1.1 Warnings and precautions 

Warning on vehicle lifting and jacking warning! 

Warning! 

To avoid any vehicle damage, serious personal injury or death when major components are 
dismantled from the vehicle and the vehicle is supported by a hoist, support with jack the 
components standing at the opposite end from which the components are being dismantled of the 
vehicle. 

Warning on battery disconnection 

Warning! 

Unless directed, otherwise, the ignition and start switch must be in OFF or LOCK position, and all 
electrical loads must be OFF before servicing any electrical component. Disconnect the negative 
battery cable if a tool or any equipment easily comes in contact with an exposed electrical terminal. 
Failure to follow these precautions may result in personal injury and/or damage to the vehicle or 
its components. 

Warning for window crack 

Warning! 

If part of glass for vehicle window is cracked but still intact, crisscross the glass for vehicle 
window with masking tape in order to reduce the risk of damage or personal injury. 

Window quick down warning 

Warning! 

Operate the power window switch when working inside the driver door. When operated, the Quick 
Up/Down function allows the window to move very quickly without stopping, which could cause 
personal injury. 

Warning on halogen bulb 

Warning! 

The halogen bulb contains high-pressure gas. Improper disposal will cause the bulb burst into 
pieces. To avoid personal injury: close the light switch and cool the bulb prior to the replacement 
of the bulb. Keep the lamp switch off until the bulb is replaced. Wear safety goggles when 
replacing the halogen bulb. When taking the bulb, only hole the lamp holder. Avoid contacting 
glass. The bulb is refrained from dust and moisture. Correctly scrap the old bulb. The halogen bulb 
must be far away from the children.

11.2.2 Description and operation 

11.2.2.1 Description and operation 

Setting for audio system 

Whenever the audio system circuit is disconnected from the battery, all the customerspersonalized 
settings in the audio system will be initialized. 

Antenna on roof 

The roof antenna is located on the front area of the roof. The antenna pole is detachable but cannot 
be folded. 

Front and rear loudspeakers 

All audio systems are equipped with six loudspeakers: the front door is equipped with two front 
door loudspeakers and two front door high pitch loudspeakers. Two backdoor loudspeakers are 
arranged at the backdoor. 

CD maintenance 

Carefully carry the CDs. CD should be stored in boxes to avoid sunlight, heat and dust. If there is 
surface contamination, use a clean and soft cloth soaked in neutral cleaning agent to wipe and 
clean the disc.

11.2.3 System work principle 

11.2.3.1 System operating principle 

Radio 

Turn the audio head unit switch to "AM" and "FM", the antenna module receives the radio signal 
and transmits to the audio head unit through dedicated circuit. The audio head unit receives the 
radio signal and then tunes out the channel you want to receive through the processing of the 
internal filter circuit. 

Amplify audio signal through internal amplifier to output to various loudspeaker through terminals 
1-2, 3-4, 5-6 and 7-8 of IP22 finally. 

CD player: 

Turn the audio head unit switch to CD mode, the audio head unit controls the CD movement. CD 
system mainly consists of the laser and turntable system, servo system, signal processing system, 
information storage system and control system, etc.. The laser is a key component of CD player, 
which consists of semiconductor lasers, optical system and electrical detector. It is a low-power 
laser diodes.Laser beam is sent through the optical lens system onto the LP information surface. 
The disc has a number of pits, when the beam hits the pit, as the reflected light is weak, 
photoelectric detector picks up weak signals; when the beam hits the smooth aluminum surface, 
there will be a strong reflected light. The detector's high or low electrical pulse output signal 
corresponds to the presence or absence of the pits. Through the RF amplifier and the internal 
comparator, "1" and "0" serial digital signals are obtained, and added to the digital signal and 
processing circuit to carry out demodulation, frame sync detection, error correction. The processed 
data will be added to the digital analog conversion (D / A) and converted into analog sound output 
to the amplifier. The amplified audio signals will be sent to each speaker through the audio head 
unit harness connector IP22 terminal 1-2, 3-4, 5-6 and 7-8.
