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
2-13For servicing items whose deadlines have expired, they should be maintained at the same intervals as before. The
intervals are recorded in maintenance schedule.
Rubber hoses
Used in cooling and heating system, braking and fuel-feeding systems should be inspected by qualified Geely
technicians according to Geely maintenance schedule.
There are all very important maintenance items. Hoses must be replaced immediately should there be any aging
or damage. Please pay attention, rubber hoses age as time goes by, and they may have problems of inflation, wear,
or crack.
Special Tips
If the vehicle is driven under one or more of the following circumstances, the maintenance items should be
carried out more frequently. See attached maintenance schedule.
A Road condition
1. drive on rough, muddy or skiddy roads
2. drive on dusty roads.
B driving condition
1. Repeat driving within 8km a few times, or when the outdoor temperature is below 0 degree centigrade.
2. Idle the car drive at a low speed for a long time, such as police car, taxi, or door to door delivery vehicles.
3. Continuously drive the car at high speed for more than 2 hours (80% of the max speed).IV. Regular inspections1. weekly schedule

2-18Section 3 Daily Maintenance of MK SedanDaily maintenance means operation of vehicle regular inspection, cleaning, fastening, and refilling according to
vehicle usage and condition on the basis of regular maintenance to make sure the vehicle is at good status. Daily
maintenance can be performed by driver or professional automotive mechanics in daily use of vehicle. But some
of the items must be conducted by professional mechanics at service shops.
1. Maintenance of air cleaner
Air cleaner filters the air that is coming into engine for the first time. Dust and other dirt filtered out gathers in the
induction tube. Air cleaner filters a lot of dust and dirty, so it must be cleaned in time.
2. Maintenance of air filter
Air filter does not only filter the dust and dirt in the air, but also keeps smooth ventilation. Its status has great effects
on the fuel economy and power of the engine, so it must be checked and maintained in time.
Before it is time to replace air filter, maintain it. Remove the filter, knock it with hand or stick to get rid of dust
on the filter and remove dirt inside the filter cover according to the cleanness of the road that the vehicle usually
runs on.
ATTENTION: do not clean the filter with wet cloth. Fasten the filter well when installing it back.
3. Maintenance of battery
Battery is used to start the vehicle and supply power to electrical facilities. Its status directly affects the regular
usage of the vehicle, especially for vehicles equipped with electrical controlled facilities. Keeping the battery in
good technical status and connections is especially important. It is necessary to often perform the following
inspections and maintenance in regular usage:
(1) Clean the outside of battery Inspect if the battery case or cover surface is dirty or has dirt, oil, or other dirty
things regularly. Clean it and keep the surface dry to avoid electrical leak caused by cover deformation.
(2) Check battery connections Bad connection between battery electrode and cable results in low engine start
speed which makes it difficult to start the vehicle or the vehicle cannot be started because of low output voltage
from battery. Loose connection at battery end leads to damage of electrical components and loss of trouble code
and other information stored in RAM of the computer system as a result of low voltage. Therefore, it is necessary
to check if the connection of cables on the battery electrode is good. When it is found loose, it must be fastened.
If there is any rust, the cables must be loosened, washed clean and be connected again.
4. Maintenance of tires and wheels
(1) Keeping tires and wheels under good condition is very important to vehicle fuel consumption and driving
safety. Therefore, inspect and maintain the tires regularly. Every 10000 km, the wheels should be adjusted. Follow
the sequence in picture 3:
Judge if there is any hidden problems in vehicle chassis mechanism by observing wear in different places, andfinding out the hidden problems does not only help you to understand
the technical status of the vehicle, but also benefits driving safety.
a. Serious wear on both edges of tire tread, means tires often
work with low tire pressure.
b. Wear of middle of the tire tread is mainly because the tires
are used with high tire pressure.This kind of wear shortens
the useful life of tires, and may result in sudden flat tire
when the vehicle runs on uneven road surface or meets any
obstacles.Usage and Maintenance of MK Series - Daily Maintenance of MK Sedan
