10. Adjust the clearance between the brake drum and brake shoe.
Poke the adjusting hole plug on the brake drum, insert the screwdriver
into the clearance-adjusting hole; rotate the clearance-adjusting gear
to expand the brake shoe until the brake disc can not be rotated by
hand. Then rotate it for 3-5 teeth in anticlockwise, rotate the brake
disc by hand at the same time, it is proper that it can rotate freely
and without the contact between the abrasion and disc. It is allowable
that the non-running-in brake shoe has the slight abrasion sensing.
When adjust the clearance, the left and right wheel must be adjust at
the same, install the adjusting hole plug after the completion of
adjusting .

Wiring Instructions(see the diagram)
with the speakers: the amplifier of main unit of this system is designed with 4-channel BTL output, each speaker must
be wired individually; the phase position and place of the speaker must be connected correctly; please disconnect the
player from the power supply before connecting the speaker so as to avoid the short-circuit.
2. Connecting main unit with the integrated display screen:
Use the specially-supplied 12-pin connector cable to connect the VFD integrated display screen and main unit.
3. Connection of power supply, output and communication line of main unit:
At first, connect the communication cable of the 20-pin connector plug to the air conditioner ECU, then connect the speaker
output line to other lines, finally connect the yellow memory power supply cord (10A fuse tube) directly to the positive role of
accumulator; when all the wiring is completed, connect the red power supply cord (1A fuse tube) to the positive power supply
of the ignition lock.
4. Connecting main unit with the antenna
T ypical antenna: insert the plug of coaxial cable of car’s antenna into the antenna socket of main unit.
Automatic antenna: insert the plug of coaxial cable of car’s antenna into the antenna socket of main unit, then connect the blue
antenna control cable in the 20-pin connector to the automatic antenna control end, connect the positive pole line of power
supply of automatic antenna to the positive pole of accumulator and the negative pole line to the earth.
5. Connecting main unit with CD-change box
CD player and the CD-change box are connected with the signal cables.
Prior to the installation, please be sure to remove three protective screws on the CD-change box and have it pasted with
ant-dust paper. If the protective screws are not removed, CD can not be played normally.
Attention: Improper wiring may result in the damage to the player!

Trouble Diagnosis and Repair of Automatic Air Conditioning System
1. Self-diagnosis of the system
CC6460K air conditioning system is designed with the system self-diagnosis function. When the air conditioning system fails to
work, the self-diagnosis function designed for the car can be activated for the initial trouble diagnosis.
Operating directions:
At first, start the engine (turn the ignition switch from OFF to ON) and press OFF , A U T O, RR and MODE successively and the
pressing of MODE switch shall last at least 2 seconds. The button must be pressed down within 10 seconds when the engine is
started (the ignition switch is turned to ON position).If the system is supposed to be released, then press A U T O switch or turn
off the ignition switch (OFF) .If one step is supposed to switch to another step, then press TEMP (HOT) or TEMP (COLD)
switch based on the needs.

5. The maintenance operation must be started after 60 seconds following the removal of negative connection of
accumulator, wrap the negative with insulating tape for insulation.
Due to the capacitance in SRS-ECU to maintain certain power to make the safety airbag release within a certain time after the
power-off of accumulator, the operation must be started after a while to avoid any possible major damaging accident caused
by the safety airbag’s improper release.
6. The parts such as SRS-ECU, safety airbag module as well as clock spring should be removed off and well preserved
providing the temperature is high enough to cause any damage(above93¡æ) in the painting operation.
The failure codes must be debugged with the diagnostic scanner following the repairing of SRS safety airbag system so as to
make alarm lamp work functionally.
