Checking Engine Oil
It is a good idea to check the
engine oil every time you get fuel.
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 9-6
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 you do not
do this, the oil dipstick might not
show the actual level.
2. Pull 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 MIN (minimum)
mark, 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 10-2.
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 9-6 for the location of
the engine oil fill cap.
Be sure to add enough oil to put the
level somewhere in the proper
operating range. Push the dipstick
all the way back in when you
are through.
