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

2-10 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.

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
