Areas of Importance
1. Clutch Rigid Pipe Installation
Before installing, check to make sure that the rigid pipe flare contact area is in good condition, the pipeline is
clean, and that there is no foreign materials.
2. Clutch Hose Installation
Check the surface of the clutch hose to make sure that there is no scuffing and that the pipeline is clean.
3. Coat grease on the U-joint of the pedal and the master cylinder.
4. Strictly adhere to the set torque guidelines when tightening the pipe fittings.
Rigid pipe and the master cylinder: M10 16±2 N·m
Clutch rigid pipe and hose: M10 16±2 N·m
5. While the clutch system is undergoing the exhausting process, make sure that all the air bubbles in
the pipeline are cleared out. Then check the brake fluid level in the reservoir, it should be between
MIN and MAX.
Troubleshooting
The numbers in the table represent the order of the possible malfunction causes, so be sure to check each part in
turn. If necessary, replace the part.

Vehicle road test methods
1. Drive the vehicle and find out if the swaying is coming from the front tires or the back tires. Then replace the
identified problem tire with a good tire (one that has been tested on t\
he same model of vehicle).
2. If unable to determine the problem tire, replace the rear wheels. Continue with the road test. If the driving
condition obviously changes, replace the original tires, and only switch one at a time until the problem tire is
identified.
3. If no obvious improvement, replace all four tires with good tires, and then replace the original tires one by
one following the steps mentioned above.
Tire's abnormal wear and tear
Tire's abnormal wear and tear includes uneven and excessive
w e a r o f t h e t i r e . T h e r e a r e m a n y c a u s e s f o r t h i s . F o r
example, improper tire pressure, tire rotation has not been
timely maintained, bad driving habits, abnormal front wheel
location, etc.
Change the tires when the below situations happen:
1. When the extents of wear and tear of the front and rear
tires are different.
2. When any of the tire's tread has uneven wear and tear.
3. When the extents of the wear and tear of the left and right
front tires are different.
4. When the extents of wear and tear of the left and right rear
wheels are different.
5. When the groove of the tire tread wear appears abnormal
and the tire's contact area starts to flatten.
Inspect the front wheel alignment when the following
situations occur:
1. When the extents of the wear and tear of the left and right
front tires are different.
2. When any of the tire's tread has uneven wear and tear.
3. When the tread pattern strip or pattern block of a front
tire's single side is badly worn.
[A]
[B]
[A]: Steering problems, air pressure not sufficient, or tire rotation has not been timely maintained. [B]: Abnormal front wheel alignment, tire or wheel structure is not the same.
Radial tire sway
Here the sway means the vehicle's front or rear part shakes
from side to side, together or individually. Tire sway is
caused by the steel wire belt inside the tire not being straight.
The sway is the most obvious when the vehicle runs at the
speed of 8-48 km/h.
Road tests can help finding malfunctioning tires. If the
malfunction is with the rear tires, then left and right shaking
or "swaying" would take place at the back of the vehicle.
Here the driver of the vehicle would feel as if someone were
pushing from one side of the vehicle.
If the malfunction is with the front tires, swaying would be
even more obvious. The metal plate in the front may seem
moving back and forth, and the driver feels as if he/she were
at the vehicle's center of rotation.
Wear marks
There are several tread wear marks (refer to location A in the
diagram shown on the left) inside of the tire's pattern groove.
These marks indicate that the tire has been worn to the point
of replacing.
Before the tire's usage limit, indicated by the remaining
pattern's depth, reaches 1.6 mm (and its main pattern groove
bottom protrudes to the same level), for your safety, please
replace the tire.
When serious eccentric wear leads to the partial protrusion
of the cord fabric level, or outside objects damage the tire to
a depth that reaches the cord fabric level or steel band level,
stop using the tire.

Deviation judging methods
"Deviation" means that, when no one is in control of the steering, the vehicle does not move in a straight line
while driving on a straight and leveled surface.
Deviation causes:
• Incorrect tire and front wheel alignment,
• Braking force is not even,
• Tire structure problems.
Tire production and manufacturing methods can also lead to vehicle deviation. For example, the arrangement of
the tires inner steel wire belt. A steel wire belt which is inside the radial tire deviating from the tires centerline
can create lateral force when the tires are rolling in a straight line. If one of the tire's diameter is larger than the
other, the tire will tend to roll to that side, this also creates lateral force (a tapering effect) leading to vehicle
deviation. When the front wheel alignment is found to be correct and in proper order, the above process is also
applicable in judging tire deviation. Rear tires cannot cause deviation.\

After solving, if working,
switch the tires again
Return the tires to their
initial positions and inspect
the front wheel alignment
After solving,
switch the tires again
Tire rotation
For equal wear or tear for the tires, please rotate the tire
positions timely. Swapping principle shown on the left.
Radial tires should be regularly switched, and add pressure
according to the regulations.
Caution:
Due to structural reasons, radial tires usually quickly
receive most of its wear on the shoulders, especially
the front tires. Do a tire rotation per 8000-12000 km,
and the tire life can increase by 20%. This makes
regular tire rotation especially useful.
Test by driving back and forth

If the problem is not yet
solved, it means the "good

If the problem is not
yet solved, replace the

Alignment area
(a) Whether there are broken connectors or protective
pipes and deformed terminals.
(b) Whether the housing is damaged.
(c) Inspect whether the clock spring's upper connector
terminal and lower corresponding connector terminal is
conducting.
Clock spring central involution
Screw in the clock spring clockwise all the way, and then
turn it 3.5 circles in the reverse direction, until the position
pin's block boss matches the block hole (as shown on the
left).
Caution: If the clock spring is not in the involution
central, the steering wheel will be unable to rotate
midway or cause clock spring circuit failure, which will
obstruct the normal operation of the SRS airbag.
6. Steering wheel and airbag module subassembly installation
(a) After pulling out the clock spring's position pin, install the steering wheel and airbag module su\
bassembly.
Caution: While installing the steering wheel and airbag module subassembly, please do not block the
clock spring wire harness.
(b) After installation, try to turn the steering wheel left and right to its proper position, and check for anything
abnormal.
7. Inspection after installation
(a) Lightly turn the steering wheel left and right to check whether there is anything abnormal or for any
strange noise. (Driver side airbag module, clock spring).
(b) Set the ignition switch to the ON position.
(c) The SRS warning lamp will remain on for 6-7 s and will then die out.
(d) If the warning lamp is always on or shows other symptoms after 6-7 s, troubleshooting must be perf\
ormed.
(e) Inspect whether the clock spring circuit is open circuited. If yes, please replace it with a new \
one.
(f) If no, check the other circuits.
Airbag Module Disposal
While discarding the airbag module or a vehicle carrying a SRS airbag, please discard according to the following
steps.
Discarding essentials of the airbag module before deployment
1. Deploy the airbag before discarding SRS airbag.
2. Deploy the airbag outside the vehicle when replacing the airbag module.
3. There may be some smoke when deploying the airbag, so make sure to operate near a smoke
detector.
4. When deploying the airbag, the sound will be very loud. Please ask nearby people to plug their ears,
and try not to operate near residential areas.
Airbag deployment
