Outside the car:
1. General condition and appearance of the car.
2. Check the condition of the wheels and tires, as well as the tightness of the wheel nuts (bolts). It is recommended to check the tire pressure (including spare tire).
3. No fuel or liquid leaks (it should be taken into account that on vehicles equipped with an air conditioning system, there may be traces of liquid caused by condensation, which is not a malfunction).
4. Condition of windshield wipers (especially in winter). It is necessary to prevent the brushes from freezing, which can lead to damage to the windshield and the wiper mechanism.
Engine compartment:
1. Check the engine oil level. Also check the technical condition of the engine oil. Inspect all engine connection points for leaks of engine oil and coolant (if leaks are detected, see. chapter "Lubrication system"),
2. Check the transmission oil level. Inspect all engine connection points for transmission oil leaks (if leaks are detected, see. chapter "Transmission").
3. Check the brake fluid level in the expansion tank. If necessary, add brake fluid to the required level. Make sure there are no visible brake fluid leaks. Depending on the design of the hydraulic drive, an expansion tank for the brake system and clutch (cars with manual transmission) there may be one or there may be two.
4. Check the engine cooling system fluid level in the expansion tank.
5. Check the fluid level in the windshield washer reservoir.
6. Check the technical condition of the auxiliary equipment drive belt. Also check the drive belt tension (check manually by pressing your thumb on the belt between the generator pulley and the water pump).
