When to Add Engine Oil
If the oil is below the cross-hatched area at the tip of
the dipstick, add at least one liter/quart of the
recommended oil. This section explains what kind of oil
to use. For engine oil crankcase capacity, see
Capacities and Specifications on page 6-105.
Notice: Do not add too much oil. If the engine has
so much oil that the oil level gets above the
upper mark that shows the proper operating range,
the engine could be damaged.
See Engine Compartment
Overview on page 6-14 for
the location of the
engine oil fill cap.
Add enough oil to put the level somewhere in the proper
operating range. Push the dipstick all the way back in
when through.
