Therefore, you should regularly check the oil level in the engine crankcase, especially before long trips.
The oil level is checked on a cold, non-running engine with the car on a horizontal surface. The level should be between the "MIN" and "MAX" marks on indicator 2 (Fig. 41). If necessary, add oil through the filler neck closed by plug 3.
After topping up, the oil level should be checked no earlier than three minutes later, so that the added portion of oil has time to drain into the crankcase.
For correct measurement, it is necessary to insert the level indicator 2 into its mounting hole until it stops.
ATTENTION! Do not allow the oil level in the engine crankcase to exceed the "MAX" mark on indicator 2 to avoid oil being ejected through the crankcase ventilation system.

Oil will enter the combustion chamber and be released into the atmosphere along with exhaust gases. On vehicles equipped with a catalytic converter, oil combustion products can cause the converter to fail.
If the readings of the oil level indicator and the on-board monitoring system1 are contradictory, the readings of the indicator should be used as a guide.
On a 16-valve engine, the 2nd oil level handle is flush with the top engine cover. The oil level should be from the top to the bottom edge of the notch on the indicator.
