General Information - Repair Instruction1-6IllustrationRemoval/installation2. For Vehicles Equipped With SRS Airbag and Seat Belt Pretensioner
Tip: This is equipped with an SRS (Supplemental Restraint System), such as the driver airbag assembly,
front passenger airbag assembly airbag ECU and seat belt pretensioner. Failure to carry out service operations in
the correct sequence could cause the supplemental restraint system to unexpectedly deploy during servicing,
possibly leading to a serious accident. Further, if a mistake is made in servicing the supplemental restraint
system, it is possible the SRS may fail to operate when required. Before servicing (including removal or instal-
lation of parts, inspection or replacement), be sure to read the following items carefully, then follow the correct
procedure described in this manual.
(1) General NoticeInstall Remove
Install Remove a. Malfunction symptoms of the supplemental restraint system are difficult to confirm, so the diagnostic
trouble codes become the most important source of information when troubleshooting. When troubleshooting
the supplemental restraint system, always inspect the diagnostic trouble codes before disconnecting the battery.
b. Work must be started after 90 seconds from the time the ignition switch is turned to the "LOCK"
position and the negative (-) terminal cable is disconnected from the battery. (The supplemental restraint system
is equipped with a back--up power source so that if work is started within 90 seconds of disconnecting the
negative (-) terminal cable from the battery, the SRS may deploy.) When the negative (-) terminal cable is
disconnected from the battery, memory of the clock and audio systems will be cancelled. So before starting
work, make a record of the contents memorized by the each memory system. Then when work is finished, reset
the clock and audio systems as before. To avoid erasing the memory of each memory system, never use a back-
up power supply from another battery.
General Information - Repair Instruction1-93. Electronic Control Device
(1) Removal of the battery terminal cable
a. Before performing electrical servicing, disconnect the nega-
tive (-) cable from the battery in order to avoid short for burnout.
b. When disconnecting the terminal cable, turn off the ignition
and light switches, loosen the cable nut and raise the cable straight
up without twisting or prying it.
c. When disconnecting the terminal cable from the battery, all
information stored in the clock, radio and DTC shall be deleted,
therefore, these information shall be checked before disconnection.
(2) Processing of Electronic Parts
a. Do not open the cover or case of the ECU unless absolutely
necessary. (If the IC terminals are touched, the IC may be destroyed
by static electricity.)
b. To pull apart electrical connectors, pull on the connector itself,
not the wires.
c. Be careful not to drop electrical components, such as ECU
or relays. If they are dropped on a hard floor, they should be replaced
and not reused.
d. When steam cleaning an engine, protect the electronic
components, air filter and emission-related components from water.
e. Never use an impact wrench to remove or install tempera-
ture switches or temperature sensors.
f. When checking continuity at the wire connector, insert the
tester probe carefully to prevent terminals from bending.
4. Remove and Installation of Engine Intake Parts
(1) If any metal scrap is mixed in the inlet pass, that may give
a bad effect to the engine.
(2) When removing and installing of the inlet system parts, close (6) Airbag ECU
a. Never reuse the airbag ECU involved in a collision when the SRS has deployed.
b. The connectors to the airbag sensor assembly should be connected or disconnected with the airbag ECU
mounted on the floor. If the connectors are connected or disconnected while the airbag ECU is not mounted to
the floor, it could cause undesired inflation of the supplemental restraint system.
c. Work must be started after 60 seconds from the time the ignition switch is turned to the "LOCK" position
and the negative (-) terminal cable is disconnected from the battery, even if only loosing the set bolts of the
airbag ECU.
(7) Wire Harness and Connector
The SRS wire harness is integrated with the instrument panel wire harness assembly. All the connectors in
the system are a standard yellow color. If the SRS wire harness becomes disconnected or the connector becomes
broken due to an accident, etc., repair or replace it.Negative(-)

immediately. It returns to ON automatically. When engine is on, do not turn the key to this position.
Notice:
(1) Do not pull the key out or turn it to LOCK before the car is fully stopped, or there will be dangers caused
by locking steering wheel or disabling some safety functions.
(2) It is prohibited to drive the car with engine turned off to ensure functioning of braking and steering booster.
(3) Do not let the key stay at ON for a long time when engine is off, or the battery fully discharged.
(4) Shift to neutral gear before ignition key is switched to START.
(5) Turn the steering wheel lightly after the car is fully stopped to make sure it is locked.
3.Unlock Steering Wheel
How to unlock steering wheel: insert ignition key, turn the steering wheel lightly and switch the ignition key.
Steering wheel is unlocked.
4.Adjust seat position
Seat back angle and cushion angle of front seats in MK-1 sedan can be adjusted.
(1) Adjust seat back angle
Turn around adjusting handle, and adjust seat back to appro
priate position.
(2) Move seat forward or backward
Steps:
a. pull adjusting handler up
b. Move the seat forward or backward, and adjust the seat to
appropriate position.
c. Put the handler down and move the seat again till it is
locked.
Attention: adjust the seat only when the car is fully stopped
to ensure safety.
(3) Front head rest can be adjusted in two ways.
Push the head rest from back to front, there are three fixed
positions to lock.If pushed over the final locking position,the
head rest can return to the original position after hand
withdraws.
(4) Fold Rear Row Seat
The seat back can be tilted forward so that the trunk will be
used to the last degree.
a. Remove the head rest
b. Unlock the seatback and fold it down.
Split seatback can be folded separately on demand.
2-10 must be running at medium speed without load. Increase the speed and load gradually with the
accumulation of breaking-in mileage.
b. Because the brake plat is not broken in on a new vehicle,in order to ensure safety and reduce wear,avoid
harsh brake, and brake for multiple times to break in the brake plate faster.
c. It is better to avoid driving vehicle on steep roads or in bad conditions during breaking-in period.
d. Pay special attention to engine coolant temperature meter and oil pressure meter.Check engine oil level
frequently and make sure engine works in normal temperature and good lubrication.
e. Maintain the vehicle strictly according to first-time maintenance requirements to bring the vehicle into
normal usage life under good condition.
7.vehicle towing
There are towing facilities both in the front and rear end of MK-1 sedan for towing other vehicles and being towed.
To ensure safety, pay attention to the following instructions when towing.
(1) Towing car Towing car should be started and shifted steadily.The speed should be no more than 40km/h.
(2) Follow the instructions below when being towed:
a. Steering system of the vehicle being towed works well.
b. Braking system of the vehicle being towed works well or it cannot be towed with a rope and must be
towed with the towing shaft instead.
c. Release park brake and shift the transmission to neutral gear when the vehicle is being towed.
d. Turn the ignition switch to ACC to allow turning signal lights,braking indicator to be turned on when
necessary.
e. The towing rope must be tensioned in the towing process.
f. If the purpose of towing is to start the engine, shift the transmission to the 2nd or 3rd gear to increase
engine speed. It is good for starting the engine.
8. Instructions to save fuel when using the vehicle
(1) Reasonable load Do not store useless articles in luggage compartment because they consumes fuel for
nothing.
(2) Correct driving style Instructions as follows:
a. When engine is started, do not heat it but press the accelerator pedal slightly, drive the vehicle slowly
and accelerate gradually.
b. Shift to higher gears when driving to allow the engine to work at appropriate engine speed and avoid
running the engine at low or high speed. The engine speed should be higher than 2500r/min when
driving, and higher than 3000r/min when up-shifting.
c. Keep the vehicle speed stable, and avoid harsh acceleration and frequent braking.
d. Pay attention to vehicle speed. Drive at high speed results in excessive fuel consumption.
(3) Organize vehicle usage well Pay attention to the following two instructions.
a. Organize vehicle usage time and avoid short trips. Because at the beginning when the vehicle is started
(around 1km), the engine has not reached its efficiency point, and the fuel consumption doubles
compared to regular.
b. Select a good driving route, avoid driving through the city or blocks with heavy traffic.
(4) Keep the vehicle under good work condition Strictly follow instructions to maintain the vehicle to make
sure the vehicle is under good technical working condition, and inspect and replace key parts that affect vehicle
fuel consumptions. For example:Usage and Maintenance of MK Series - Usage of MK Series
2-11a. Keep air filter clean, Block of air filter affects engine air induction efficiency and increases fuel
consumption. So it must be cleaned and replaced in time.
b. Keep ignition system under good work condition. Bad connection or electricity leak of ignition coil and
power distributor or inappropriate gap or carbon residue of spark plug decreases ignition power supply
and efficiency, which leads to engine fuel consumption increase. So they need regular inspection and
repair to keep their good work condition.
c. Fuel feeding system works well. Often check if fuel feeder pipe leaks, and check if injectors and other
parts perform well on regular basis (electrical injection engines).
d. Keep regular tire pressure. If the tire pressure is not enough, vehicle rolling resistance increases and
engine fuel consumption increases accordingly. So tire pressure must be checked on time (around once
a week).Usage and Maintenance of MK Series - Usage of MK Series
