ground.

for the oil to drain into the oil pan.
3. Set the parking brake and make sure
that the transmission is in park (P).
4. Open the hood. Protect yourself from
engine heat.
5. Locate and carefully remove the engine
oil level dipstick.
6. Wipe the dipstick clean. Insert the
dipstick fully, then remove it again.
7. Put the dipstick back in and make sure
it is fully seated.
• If the oil level is between the lower and
upper holes, the oil level is acceptable.
DO NOT ADD OIL.
• If the oil level is below the lower hole,
add enough oil to raise the level within
the lower and upper holes.

additives, cleaners or other engine
treatments. They are unnecessary and
