2-85. Actions to ensure vehicle working condition and safe driving.
(1) To make sure of driving safety, execute the following inspections before driving.
a. Inspect fuel level, and add fuel when necessary.
b. Inspect illuminating lights, turning signal lights, braking signal lights to see if they work.
c.Check the position of rearview mirrors.
d.Check if breaking system functions well.
e.Check if glass of all the lights, windshield is clean.
(2) Regular inspection Perform the following regular inspections to ensure the vehicle work condition and
driving safety.
a. Check engine oil level. Park the vehicle on flat road; check the oil level with engine oil level indicator
at least 10 minutes after the engine is stopped. The oil level should be between the two marks. If it is
lower than "L" mark, add some oil; if it is higher than "F" mark, there is excessive oil, so release it.
Or investigate the cause of high oil level.
The volume between the lowest oil level ("L") and highest oil level ("F") is 1.4L.
b. Check engine coolant level. Check the level when the engine is cool. The coolant level should be between
LOW and FULL. If it is lower than "LOW", add coolant. If the coolant is much lower than Min (every
coolant fill is more than 1L) or the vehicle requires frequent fills,investigate if there is any problem with
the cooling system.
To keep the function of coolant, replace coolant every two years at the beginning of cold winter.
c. Check brake and clutch fluid level (sharing a reservoir). Brake fluid level should between the Max and
Min marks. And it is better to keep it close to the Max mark. Add fluid in time when there is not enough
fluid.
d. Check power steering fluid tank. The level should be between Max and Min marks. Refill when there
is not enough steering fluid to avoid pump stuck. It is strictly prohibited to run the vehicle without
steering fluid in any circumstances.
e. Check the charging status of battery and if the connection of battery wires is good.
f. Check tire status and pressure
g. Check the status of wipers.
(3) Observe warning lights and indicators on instrument panel.
a. There are various warning lights and indicators on the instrument panel of MK-1 sedans to indicate and
warn abnormal operations of engine, braking, and charging systems.
b. Pay attention to these lights when driving.When the warning lights or indicators are on,stop the vehicle,
check the vehicle and resolve the causes to make sure the vehicle works well or drives safely.
6. Correct ways to use new cars
Reliability and stability of components in new cars and recently repaired cars still need to be confirmed, and
relative parts are not broken-in, so they must be used carefully to ensure driving safety, to avoid abnormal damage,
and to extend the useful life of the car.
(1) Before driving inspection The following inspections must be performed on the new car to ensure car safety
and reliable operation:
a. Check if instrument panel, warning lights, and indicator, front and rear wiper and washer, and switches
work.
b. Check if the fastening of driveline, steering, suspension, wheels and other connection parts is good.Usage and Maintenance of MK Series - Usage of MK Series

2-9 c. Check levels of braking fluid, engine coolant, engine oil, transmission oil, power steering fluid, and
washing fluid to see if there is any leaking.
d. Inspect if brake pedal, clutch pedal, accelerator pedal, transmission shifter, steering wheel, choke are
loose or stuck. The free travel of clutch pedal is 5~15mm, the free travel of brake pedal is 1~6mm and
the free play of steering wheel is less than 30mm(measurement point at margin of steering wheel). if it
is out of this normal range, the clutch needs to be tuned.
e. Inspect if the connection of battery, lamps and signal lights are normal, and if the wire routing and
position are correct and not loose.
f. Inspect if the tire pressure is correct.
(2) On-road inspection If the inspection result of the above items is good, start the engine and test the car on
road, and perform the following inspections.
a. Acceleration pedal, see if the operation is smooth and if it is loose.
b. Clutch, see if there is any stuck or abnormal noise, and slip when driving.
c. Transmission,check if shifting is smooth,or rough and wrong shifting.Inspect if the display of A/T
shift lever is normal.
d. Steering, check if steering is light and smooth, and if the steering wheel turns back after steering.
e. Brake pedal, apply brake pedal to check if the braking functions well when vehicle speed is at
40km/h and if the vehicle runs off track.
f. Park brake, when parking brake handler is pulled, there should be 6~9 clicking sounds. Pull park brake
when vehicle is running at the speed of 20km/h and transmission is at neutral gear to see if it brakes.
g. Vehicle speed meter, observe the vehicle speed meter while driving. When speed changes, check if the
indicator is moving steadily or shakes.
h. Heating and air-conditioning.Try every control button to see if both heating and cooling system work
well.
i. Abnormal noise, listen carefully to see if there is any abnormal noise from engine, drive line system or
any other parts of the vehicle at a steady speed and during accelerating, and decelerating.
(3) Inspection after test ride check if there is anything abnormal in the vehicle while driving and conduct the
following inspections after the vehicle is parked.
a. Check electrical fan When engine coolant temperature is beyond 92.5°C, the radiator fan should be
running; When A/C is on and the pressure of refrigerant is more than 1.5 cooling ton, air conditioning
cooling fan should be running.
b. Check headlamp, method: park the car 5m away from the inspection surface (inspection board, curtain,
or wall) to the front bumper, and check if the beam from headlamp is good. The upper level if headlamp
should be 540mm above the ground, and the distance between headlamps on the two sides is 900mm.
c. Inspect engine idle speed,idle speed of hot engine is 800r/min±50r/min,when A/C compressor works,
the idle speed should be 900r/min±50r/min. If idle speed is abnormal, adjust the idle speed adjust
ment screw to adjust it.
(4) Usage of new cars in breaking-in period Follow the instructions below in the first 1500~2500km breaking
mileage to avoid wear and abnormal damage in breaking-in period, and to improve vehicle performance, fuel
economy and to extend vehicle useful life.
a. Drive steadily during breaking-in; do not accelerate harshly to avoid running engine at high speed.
Engine should not exceed 4500r/min in any gears. Especially at the early stage of breaking-in, vehicleUsage and Maintenance of MK Series - Usage of MK Series

2-12Section 2 Maintenance Category and Content of MK SedanAs the vehicle is being used, its technical performance changes as the mileage accumulates and being affected by
various factors, which results in decrease of power, fuel economy, safety, and increase of emission pollutions,
noise and incidents. So timely maintenance during vehicle usage eliminates potential risks and prevents incidents
from happening, improves vehicle integrity and technical functionality, and prolongs useful life of the vehicle.
According to the vehicle technical requirements and usage history, maintenance of freedom Cruiser sedan can be
classified into several categories.I. first time maintenanceFirst time maintenance is also called breaking-in maintenance. It is performed when the vehicle mileage has
accumulated to 1500~2500km in breaking-in period. First time maintenance must be conducted at the appointed
service shops. It includes:
1. Check if there is any leak in engine, transmission, and differential. Fix if there is any.
2. Replace engine oil filter, engine oil and ATF for A/T.
3. Check the level of engine coolant, braking fluid, windshield washing fluid, power steering fluid and if there
is any leak. Refill if the level is too low and repair if there is any leak.
4. Check if there is any damage in triangle arm and ball joint, connection ball joint, triangle arm flexible hinge,
or the ball joint is loose. If there is, fix or replace it.
5. Check if the drive shaft dust cover is damaged. If there is, replace it.
6. Check if there is any leak in steering mechanism, or front and rear absorber and fix it there is any.
7. Check the tire pressure, front 230kpa, and rear 210kpa.II. Regular maintenanceAfter first time maintenance, the vehicle is in regular usage life. During regular use, the vehicle needs to be
maintained regularly according to the way it is used in.
1.Regular maintenance for vehicles used under extreme bad conditions. Any of the condition below is defined
as extreme bad condition:
(1) Frequent start.
(2) Often drive the vehicle in dusty circumstances.
(3) Drive the vehicle in hot areas (such as in summer in the south).
(4) Often drive in cold areas (often runs short trips, engine temperate cannot reach regular work temperature).
