Engine Oil
Inspection
1. Check engine oil with the engine off and the car parked on level ground.
2. Make certain that the oil level indicated on the dipstick is between the upper and lower marks.
3. If the level has dropped close to the lower mark, add oil until it reaches the upper mark.
CAUTION: Insert the dipstick carefully to avoid
bending it. Replacement
CAUTION: Remove the drain plug carefully while the
engine is hot, the hot oil may cause scalding.
1. Warm up the engine.
2. Drain the engine oil.
