door guard plates are all installed with window regulator switches.
Automobile
glass
Windshield is laminated glass, front and rear door glass is tempered glass, trunk door
glass is heating & defrosting tempered glass with resistance wire.
Outer rearview
mirror
Elite type: electrically actuated convertible body and electronically controlled mirror
with defroster.
Luxury type: manually folded body and electronically controlled mirror without
defroster.
Comfort type: manually folded body and manually adjusted mirror without \
defroster.
Inner rearview
mirrorFlexible with anti-glare function
Seats
Driver & front passenger seats, independent seats. For front and rear seats, backrest
angle and seat headrest are both manually adjustable. Second row seats use a three-
seat arrangement. The seats' front and back positions and backrest angles are
nonadjustable. Seat headrests are both manually adjustable, back of the seat can be
folded forward, and the middle seat includes a child seat belt.
Seat belt
The front seat has two kinds of seat belts, complex equipment type being an
electronic preload three-point seat belt, and simple equipment type a non-preload
three-point seat belt. Advanced configuration uses the electronic preload three-point
seat belt, while simple configuration uses the non-preloaded three-point seat belt.
The rear seat belt uses a normal three-point seat belt.
Sun visor
Left and right sun visors both have cosmetic mirrors, and the sun visors can be
rotated up and down and from side to side, the up and down rotation can be held at
any position.
Front and rear
bumperBumper assembly can withstand collision speeds of 8 km/h.
Washer
Equipped with front and rear wiper, one 5th gear thrust washer reservoir, two motors,
two sets of pipelines in the front and rear, two washing nozzles with one in the front,
and the other in the back.

Double-colored wire: Primary color is Red, secondary color is Blue, mark\
ed as RBl.
0.5BrGr means Brown wire with a Gray fine wire, and sectional area is 0.\
5 mm2.
Areas of importance in circuit maintenance
1. Before operating any electronic devices, and when tools or maintenance devices may easily make
contact with an uncovered electronic terminal, please make sure to turn the ignition switch to the LOCK
position, and then disconnect the battery's negative cable to avoid injury or vehicle damage. When the
ignition switch is on the ON position, please do not disconnect the battery's connecting wire or take out
the power's fuse, regardless if the engine is running or not.Otherwise it would seriously damage the
ECU and related microelectronic devices such as sensors.
2. When changing the fuse, please make sure that the new fuse possesses the proper current rating,
and is not above or below this rating.
3. When repairing the wire harnesses of the airbag and pretensioner, only specified contact points,
plugs, and wires are allowed to be used.
4. Before repairing the wire harness, make sure to eliminate any factor that might cause damage,
for example, the edge of a vehicle body part is too sharp, or the used electronics are damaged or
corroded.
5. Shielded wire should not be repaired, it must be replaced entirely once it is damaged.
6. Unless it is specified during the test, please do not use an analog multimeter to test the ECU and
sensor, instead use a high-impedance digital multimeter (internal resistance should be ≥10 kΩ) or a
vehicle multimeter for inspection.
7. When inspecting the connector with a digital multimeter, take the waterproof rubber cover off the
connector, and tightly insert the test pen along the connecting terminal. Don't use too much force, as
to avoid cracking the connector.
Circuit inspection steps
The principle of troubleshooting is to confirm the "possible cause". Once the possible cause is confirmed, the
components that need to be inspected are limited to the components that are related to the possible cause. The
confirmed possible cause should be based on theory and be supported by facts, but not just by intuition. If
one tries to solve the problem but does not adopt the proper troubleshooting steps, it may make the problem
worse. Then the possible cause not only can't be confirmed, but also maintenance can't be performed properly.
Troubleshooting should adhere to the four steps below:
1. Observe the symptoms carefully, inspect if there is anything else abnormal, and record it.
2. While confirming the possible causes, study the circuit diagram carefully, and regard it as a whole
system in order to understand the circuit. Thorough knowledge of switches, relays, and other
electronic components is obligatory for proper analysis.
3. Inspect and eliminate the problems one by one until the cause is found.
4. After the malfunction is fixed, make sure to check if the inspected system is working properly, and also
check if the maintenance may have caused any new problems.
