Engine Oil
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.
SeeEngine Compartment Overview on page 350
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 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, you will need to add at least
one quart/liter of oil. But you must use the
right kind. This section explains what kind of
oil to use. For engine oil crankcase capacity,
seeCapacities and Specications on page 454.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.
SeeEngine
Compartment Overview
on page 350for the
location of the engine
oil ll cap.
Be sure to 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 you are through.

Automatic Transaxle Fluid
When to Check and Change Automatic
Transaxle Fluid
A good time to check the automatic transaxle uid
level is when the engine oil is changed.
Change the uid and lter at the intervals listed
inAdditional Required Services on page 464,
and be sure to use the transaxle uid listed
inRecommended Fluids and Lubricants
on page 470.
How to Check Automatic
Transaxle Fluid
Because this operation can be a little difficult, you
may choose to have this done at the dealership
service department.
If you do it yourself, be sure to follow all the
instructions here, or you could get a false reading
on the dipstick.
Notice:Too much or too little uid can damage
the transaxle. Too much can mean that some of
the uid could come out and fall on hot engine
or exhaust system parts, starting a re. Too
little uid could cause the transaxle to overheat.
Be sure to get an accurate reading if you check
the transaxle uid.
