If the low engine oil level message appears on the
instrument cluster, it means you need to check your
engine oil level right away. For more information,
see
Low Engine Oil Level Message on page 3-55.
You should check your engine oil level regularly; this is
an added reminder.
Checking Engine Oil
It’s a good idea to check your 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 is
located at the front of the
engine compartment,
near the center. The
dipstick handle has a
bright, yellow loop design
for easy identification. See
Engine Compartment
Overview on page
5- 12
for more information on location.
Turn
off the engine and give the oil several minutes to
drain back into the oil pan. If you don’t, the oil
dipstick might not
show the actual level.
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.

Notice: Don’t add too much oil. If your engine
has
so much oil that the oil level gets above the
cross-hatched area that shows the proper operating
range, your engine
could be damaged.
When to Add Engine Oil
If the oil is at or below the cross-hatched area at the tip 01
the dipstick, then you’ll need to add at least one quart of
oil. But you must use the right kind. This part explains
what kind of oil to use. For engine oil crankcase capacity.

The engine oil fill cap is
located behind the engine
oil dipstick. See

Compartment Overview
on page
5- 72 for more
information on location.
Be sure to
fill it enough 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’re through.

Automatic Transaxle Fluid
When to Check and Change
A good time to check your automatic transaxle fluid
level is when the engine oil is changed.
Change both the fluid and filter every
50,000 miles
(83
000 km) if the vehicle is mainly driven under one or
more of these conditions:
In heavy city traffic where the outside temperature
regularly reaches 90°F (32°C) or higher.
In hilly or mountainous terrain.
When doing frequent trailer towing.
Uses such as found in taxi, police or delivery
service.
If you do not use your vehicle under any of
these conditions, change the fluid and filter at
100,000 miles (1 66 000 km).
See
Part A: Scheduled Maintenance Services
on page
6-4.
How to Check
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 fluid can damage your
transaxle.
Too much can mean that some of the fluid
could come out and fall
on hot engine or exhaust
system parts, starting a fire.
Too little fluid could
cause the transaxle to overheat. Be sure to get an
accurate reading if you check your transaxle fluid.
Wait at least
30 minutes before checking the transaxle
fluid level
if you have been driving:
When outside temperatures are above 90°F (32°C).
At high speed for quite a while.
In heavy traffic - especially in hot weather.
While pulling a trailer.
To get the right reading, the fluid should be at normal
operating temperature, which
is 180°F to 200°F
(82°C to 93°C).
Get the vehicle warmed up by driving about
15 miles
(24 km) when outside temperatures are above 50°F
(1 0°C). If it's colder than 50°F (1 OOC), you may have to
drive longer.
