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,

6. Disconnect the two hoses from the auxiliary valve of
compressor;
Cover the opening joint with cork right away to prevent the wet
gas entering in to the system.
7. Tear down the compressor:
(a) Tear down the fan cover;
(b) Loosen the driving belt;
(c) Tear down the fixing bolts of compressor bracket and the
compressor.
Mount of compressor
1. Mount the compressor with fixing bolts;

2. Mount the driving belt correctly;
Requirement for belt tension: the tension belt is allowed
to reduce (9-13)mm under 98N after the compressor
runs for five minutes;
3. Connect the two hoses to the auxiliary valve of
compressor;
