Engine Oil

Checking Engine Oil
It is a good idea to check the
engine oil level at each fuel fill. In
order to get an accurate reading, the
oil must be warm and the vehicle
must be on level ground.
The engine oil dipstick handle is a
yellow loop. See Engine
Compartment Overview on
page 5-10 for the location of the
engine oil dipstick.
1. Turn off the engine and give the
oil several minutes to drain back
into the oil pan. If this is not
done, the oil dipstick might not
show the actual level.
2. Pull out the dipstick and clean it
with a paper towel or cloth, then
push it back in all the way.
Remove it again, keeping the tip
down, and check the level.
When to Add Engine Oil
If the oil is below the cross-hatched
area at the tip of the dipstick,
add at least one quart/liter of the
recommended oil. This section
explains what kind of oil to use. For
engine oil crankcase capacity,
see Capacities and Specifications
on page 5-94.
Notice: Do not add too much oil.
If the engine has so much oil
that the oil level gets above the
cross-hatched area that shows
the proper operating range,
the engine could be damaged.
See Engine Compartment Overview
on page 5-10 for the location of
the engine oil fill cap.
Add enough oil to put the level
somewhere in the proper operating
range in the cross-hatched area.
Push the dipstick all the way back in
when through.
