2. Regular Maintenance Process

2.1. Standard first maintenance (5,000 KM) work procedure

2.1.1. Receive the vehicle to be maintained, wear the “four-piece series” (seat cover, steering

wheel cover, shift lever cover, driver’s foot pad) on the vehicle, drive the vehicle to the

lifting jack, and support the vehicle;

2.1.2. Prepare for the related tools and special devices;

2.1.3. Wear the left and right fenders protective covers and front protective covers on the vehicle

to be maintained;

2.1.4. Replace the engine oil, and oil cleaner (refer to the replacement above-mentioned in this

manual);

2.1.5. Check transmission oil: Check the leakage of transmission oil viewing from the engine

compartment; and then lift up the vehicle and check the leakage of transmission oil viewing

from the bottom of vehicle;

2.1.6. Check the oil/fluid: Check the levels of brake fluid, antifreeze fluid, glass cleaning fluid

and power steering oil, and the leakage of the related pipelines;

2.1.7. Check the door lock, hinge and stopper: Check the working condition of all door locks,

hinges and stoppers, and appropriately add the lubrication oil if there is abnormal sound or

the resistance is big;

2.1.8. Check the air cleaner: Clean the element (with the high-pressure air), and replace it, if

necessary;

2.1.9. Check the dislocation or damage of the dust cap of constant velocity joint;

2.1.10. Check the damage of steering tie rod end and its dust cap;

2.1.11. Check the thickness of brake lining/shoe, and replace it, if necessary. The standard

thickness of front brake lining is 10 mm, with the serviceability limit of 3 mm, and the

remaining thickness while the brake lining thickness limit shall not be less than 3 mm; and

the standard thickness of rear brake lining is 5 mm, with the serviceability limit of 1 mm,

and the remaining thickness while the brake lining thickness limit shall not be less than 1

mm;

2.1.12. Check the suspension components: Check its abnormal looseness or friction, damage, and

leakage and damage, the working condition of the system, and repair or replace it, if

necessary;

2.1.14. Check the A/C system: clean the element (with the high-pressure air), check its pressure

(it is different according to the various working conditions, etc, and the reference value

while idling is:low pressure: 2.5 - 3.0 Bar; high pressure: 15 - 17 Bar), the leakage,

abnormal sound, odor, and the working condition;

2.1.15. Check tire (including spare tire): Check the depth of tire pattern, which the depth of tire

pattern shall not be less than 1.6 mm; regulate the air pressure of tire: 230kPa for front
