2-19 (4) Tire wear limits When the wear limit mark on tire shows up as the tire wears, it must be replaced with new tires (wear limit mark
indicates the thickness of tire pattern is 1.6mm).
5. Maintenance of wiper and washer
Status of wiper and washer directly influences windshield and driver's view. So, pay attention to wipers and
washers.
(1) Wiper Check if the wiper blade has any damage, deformation, which affects windshield wiping quality
and if the wiper works well. If wiper blade does not wipe well or the wiper does not work well, fix or replace it
in time.
(2) Washer Check washing fluid level in the tank, and refill when necessary. To get best washing effects, use
specified washing fluid, refill slowly, and pay attention not to mix it with any dirt. Mix the washing fluid with some
alcohol in winter to avoid freezing.
6. inspect and adjust headlampIncorrect beam of the headlamps affects safety of driving in the dark. So they must be inspected regularly, and be
adjusted when necessary.
7. Maintenance of inside the vehicle
The major content of maintenance inside the vehicle is cleaning, to keep the vehicle clean and provide fresh and
pleasant driving circumstance. The key points of indoor cleaning are:
(1) Ways to remove stains Get rid of dust before trying to remove stains, and then apply appropriate cleansing,and wipe the stains off with clean, soft, and not too wet cloth repeatedly.
(2) Cleansing It is better to remove stains on textile and man-made leather with hydro solvent made from soap
fluid and surface active agent. Be careful to avoid using any cleansing because they may corrode the synthetic
decoration materials more or less. Ball-pen and lipstick marks can be removed with alcohol, grease can be removed
with low Ron value gasoline, and chocolate and sugar stains can be cleaned with ammonia spirit, asphalt must be
cleaned with special cleansing.Tire Specification Tire Pressure (KPa)
Front Tire 185/60R15 84H or 175/65R14 82H 230
Rear Tire 185/60R15 84H or 175/65R14 82H 210c. Wavy wear on the tread is related to its quality and positioning of the wheels. Find out the root cause
and eliminate any problems.
d. Serious wear on the outer side beside the tread of steering wheels means the wheel outward leaning angle
is too big; wear on the inner side beside the tread means the leaning angle is too small.
e. When the toe-in value is getting smaller, the wear on the outer side of tread is in shape of saws. On the
contrary, when the inner side has the saw shape wear means the toe-in value is too big.
(2) Maintenance
a. Keep the tire pressure to specified value under any circumstances. Measure the pressure on cold tire
b. Check tire pressure regularly, and remove any indented objects that may stick through the tires.
c. Avoid oil, gasoline, and brake fluid on tires.
d. When replaced with new tires, the wheels need to be balanced and adjusted again. Or the vehicle may
shake when running at high speed and bear abnormal wear.
e. Do not mix tires of different structure, pattern, or brand on one vehicle.

2-20 (3) Long time exposure to sun damages interior. So it is better to use covers on upper seat backs, and rear
separation board that are exposed to sun.
8. Maintenance of body exterior
Body exterior is to keep body cleanness and brightness to give the impression of beauty and comfort, and to avoid
rust and abnormal paint peeling off. The key points of body maintenances are:
(1) Wash body using the method below:
a. Wash the dirty things off the body by pressurized water, and then clean the body with
soft cloth of sponge from up to down.
b. Dry body surface with good white cloth. Apply brake pedal several times when driving
after the car is washed to get rid of water in braking system.
c. Do not wipe the body when it is dry. Do not clean paint surface and glass with gasoline,
coal oil, narkosid, strong lye or alcohol.
(2) Cleaning windshield glass
Do not use silicon-bronze radical products. To get better cleaning effects, use special glass cleanser.
(3) Cleaning asphalt on the body
Do not peel the asphalt off from body or bumper, but use special cleanser
(4) Paint
Scratches or slight damages can be fixed with special paint spray. It dries in the air.
(5) Cleaning exterior decoration parts and aluminum parts. Wash with water with soap fluid or cleanser, and wash with clean water. To keep the gloss of painted surface,
wax on the surface after it is dry. (6) Polish and wax the body paint polishing and waxing keeps the body bright and pretty, and protects the paint
as well.
a. Polish in winter. Make sure the vehicle body is absolutely clean and dry before
polishing, polish with fluid or milky wax.
b. Vehicle body must be absolutely dry and clean before waxing. Use waxing tools (soft
table tissue or smooth cotton cloth) to cover the body paint surface evenly with wax.
Check if the vehicle body is covered by wax: spray some water onto the paint surface,
if water drops are formed, that surface is waxed, otherwise, clean the surface and wax
it again. Attention: do not wax under sun, or in cold weather.
Attention
1) When using high pressure washing machine, do not point the washing sprayer to transmission, steering
mechanism and other rubber protection parts, or exterior decoration parts, roof welding lines, heat radiator
or engine compartment.
2) The bottom of vehicle body is made of anti-corrosion material,and has been through anti-corrosion process.
After the vehicle has been running frequently on roads de-frozen with salt for some time, clean engine
compartment and lower part of vehicle body and take some protection actions.Usage and Maintenance of MK Series - Daily Maintenance of MK Sedan
TableEngine AssemblyEngine Inspection3-2 Note:
Check the belt distortion at the specified point (see Figure 1-1).
When mounting a new belt, set the tensioning force to specified value.
After the belt has been operated more than 5 minutes, check and ensure the distortion not exceeding specified
value. (2) Make sure that the coolant level is above the neck of the radiator.
(3) Put the radiator cover in place, pressurize to 2.0Mpa, and keep the pressure for 1minute unless the coolant
leaks. (Mount a tester on the radiator cover, start the engine, and then shut down under a pressure 2.0Mpa).
(4) Check whether the coolant quantity in the dilatation can is between the mark "Low" and "Full".
(5) Check whether the radiator cover is clean; test whether the opening pressure of the main valve is 107.8KPa
with a radiator cover tester. The minimum opening pressure is 58.5KPa.
6. Check the battery.
(1) The terminal voltage of the battery is 12.5-12.9V at 20°C, and charge when the voltage value is less than
the specified value. Check whether the fusible cutout and the fuse are loose, corrosive or on.
7. Check the air filter.
(1) Whether the cover, the case or the element of the filter is distorted, corroded or damaged.
(2) Whether the air hose is damaged.
(3) Whether the air chamber is distorted or damaged.
(4) Whether the air filter element is blocked, polluted or damaged. If the filter element is blocked slightly,
remove the dirt by blowing the element from above.
(5) Whether there is any pollutant or dirt on the air filter support.
8. Check the spark plug.
(1) Spark generation.
a. Disconnect the coupling of the injector.
b. Remove the spark plug from the secondary wire.
c. Remove the spark plug.
d. Connect the spark plug to the secondary wire.
e. Ground the spark plug.
f. Start the engine, and check whether spark is generated.
Prompt: The starting time is not more than 1-2s.
(2) Clean the spark plug: The air pressure is not greater than 588kp and the time is not more than 20s.
(3) Check whether the thread and the insulator of the spark plug are damaged. Replace if necessary.
(4) Check the electrode gap of the spark plug: 0.8±0.1mm for MR479Q and MR479QA; 1±0.05mm for
MR481QA.
