Engine Oil
Inspection
1.Park the vehicle on level ground, and turn off theengine. Allow the oil a few minutes to drain backinto the oil pan so the dipstick will show the actuallevel.
Make certain that the oil level indicated on the dip_stick is between the upper and lower marks.
lf the level has dropped close to the lower mark.add oil until it reaches the upper mark.
CAUTION: lmert thc dipstick car€fully to avoid b€nd_ing it.

Replacement
CAUTION: Removo the drain boli carefully while lhoengine is hot; the hot oil may causo scalding.
:1. Warm up the engine.
2. Drain the engine oil.
