which not only presents the maintenance procedure, but also clearly describes the technical requirements and
application limit.
Part III introduces the electric system and air-conditioning system of the automobile body, which mainly
covers such items as the location and content of protective box, power supply system, starting system, lighting
system, combination instrument, backup radar system, wiping and washing system, center control locking and
power window system, acoustical equipment system, full wire harness and air-conditioning system, etc. Electric-
ity diagrams for those electric systems are given in this manual so as to facilitate the maintaining technicians to
find out the problem easily and quickly.
Part IV introduces the external and internal body decoration, which mainly covers the dismantling, inspect-
ing and assembling requirements of the engine cover, front and rear doors, adhesive strip of body collision
avoidance, wheel shield, wrapping angle of wheel-shield and exterior trim panel, front and rear windshields,
side-window glass, rear-door glass, rear platform of cargo compartment, rear door, instrument panel, safety belt,
seat, tail-fin, luggage rack, and reserve tire bracket etc. The dimensions of vehicle body and frame are also given
to maintaining staff for reference during their repairing.
During the narrations of each part, items such as troubleshooting, maintenance notice, maintenance data
and application limit, fastening torques of bolts and nuts for special purpose, SST, SSM and lubricant materials
and so on are also introduced. Various maintenance data are briefed in attachment for reference.
Altogether, this manual is comprehensive in content, visual in illustration, clarifying in requirement and
plain in language. It can be referred by the maintaining staff, technicians and professional managing staff.

Overall Repairing Description
1. Keep the vehicle clean and prevent it from
damage with guard plate, seat and floor cover
cloth.
2. Put down the dismantled parts in order during
the dismantle process so as to facilitate the re-
assembly
3. Observe the following items:
a) Disconnect the cable cathode from the
accumulator terminal before the electric
operation;.
b) Disconnect the cable from the cathode
connected to the vehicle body when check-
ing or repairing the accumulator where
necessary.
c) In order to avoid the damage of terminal
post of accumulator, loose the bolts first,
then pull up the cable vertically when
dismantling, dont wring it or prize it.
d) Clean the terminal posts of the accumula-
tor with dishcloth, and do not scrape them
with file or other similar tools to avoid
damage.e) Mount the cable terminal on the post with loosened nut, then
fasten the nut. donít tap the terminal onto the post with
hammer.
f) Be sure to check whether the cover of positive terminal (+) is
well located or not.
4. Check all hoses and wire plugs to verify whether they are
connected solidly and correctly.
5. Parts that cannot be reused after being used.
a) The following parts should be changed with new one regularly:
split pin, sealing washer, O-ring and oil seal, etc.
b) parts that cannot be reused after being used is marked with
in the element figure.
6. Pre-coated parts
The pre-coated parts including the bolt and nut are coated with
locking seal glue in factory.
a) In case the pre-coated parts are moved due to its fastening,
loosening or other causes, they must be coated again with the
specified seal glue.
b) Coating procedure of pre-coated parts
1) Clear away the former seal glue from the screw thread of
the said parts.
2) Dry the parts with compressed air.
3) Coat the screw thread of the parts with the specified
locking seal glue.
c) The pre-coated parts are marked with the in element
figure.
7. When necessary, sealing agent or sealing ring to prevent the
leakage.
8. Each specification shall be followed strictly. And the torque
spanners should be used.
9. Determine the necessity of using the special service tools (SST)
or special service materials (SSM) according to the real situation.
SST and SSM must be used where necessary and the repairing
should be in accordance with the repairing approach. SST list
and SSM list are attached to this manual.
10. Be sure to check whether the rated current of the new fuse is
