What to Do with Used Oil
Used engine oil contains certain
elements that can be unhealthy for
your skin and could even cause
cancer. Do not let used oil stay on
your skin for very long. Clean your
skin and nails with soap and water,
or a good hand cleaner. Wash or
properly dispose of clothing or rags
containing used engine oil. See the
manufacturer’s warnings about the
use and disposal of oil products.
Used oil can be a threat to the
environment. If you change your own
oil, be sure to drain all the oil from the
filter before disposal. Never dispose
of oil by putting it in the trash, pouring
it on the ground, into sewers, or into
streams or bodies of water. Recycle
it by taking it to a place that collects
used oil.
Automatic Transmission
Fluid
When to Check and Change
Automatic Transmission Fluid
Check the fluid in the transmission
and differential at the intervals listed
inScheduled Maintenance on
page 10-3, and be sure to use
the transmission fluid listed in
Recommended Fluids and
Lubricants on page 10-15 .
How to Check Automatic
Transmission Fluid
This operation can be difficult, you
may choose to have this done at the
dealer/retailer 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. Wait at least 30 minutes before
checking the transmission 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 158°F to
176°F (70°C to 80°C).
Get the vehicle warmed up by
driving about 15 miles (24 km)
when outside temperatures
are above 50°F (10°C). If it is
colder than 50°F (10°C), you
may have to drive longer.

Protection Plan? The Plan
supplements the vehicle warranties.
See the Warranty and Owner
Assistance booklet or your dealer/

Notice:
Maintenance intervals,
checks, inspections, replacement
parts, and recommended uids
and lubricants as prescribed in
this manual are necessary to
keep this vehicle in good working
condition. Any damage caused
by failure to follow scheduled
maintenance might not be covered
by the vehicle warranty. Proper vehicle maintenance not only
helps to keep the vehicle in good
working condition, but also helps the
environment. All recommended
maintenance is important. Improper
vehicle maintenance can even affect
the quality of the air we breathe.
Improper fluid levels or the wrong tire
inflation can increase the level of
emissions from the vehicle. To help
protect the environment, and to keep
the vehicle in good condition, be sure
to maintain the vehicle properly.
Using the Maintenance
Schedule
We want to help keep this vehicle in
good working condition. But we do
not know exactly how you will drive it.
You might drive very short distances
only a few times a week. Or you
might drive long distances all the
time in very hot, dusty weather.
You might use the vehicle in making
deliveries. Or you might drive it to
work, to do errands, or in many
other ways.

Footnotes
†The U.S. Environmental Protection
Agency or the California Air
Resources Board has determined
that the failure to perform this
maintenance item will not nullify the
