What to Do with Used Oil
Did you know that used engine oil contains certain
elements that may be unhealthy for your skin and could
even cause cancer? Don’t 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 throw
away clothing or rags containing used engine oil. (See
the manufacturer’s warnings about
the use and disposal
of
oil products.)
Engine Cover
Removing the Engine Cover
1. Move both front seats as far back as they will go.
Used oil can be a real threat to the environment.
If you
change your own oil, be sure to drain all free-flowing
oil
from the filter before disposal. Don’t ever dispose of oil
by putting
it in the trash, pouring it on the ground, into
sewers, or into streams or bodies of water. Instead,
recycle
it by taking it to a place that collects used oil. If
you have a problem properly disposing of your used oil,
ask your dealer, a service station or a local recycling
center
for help.
2. Remove the instrument panel extension
by removing
the two nuts that secure it in place.

Installing the Engine Cover
1. Lift the engine cover into the vehicle and slide it all
the way forward. Make sure the rubber seal is over
the latches.
2. Install the two bolts at the engine cover.
3. Put the heater duct over the engine cover studs. Push
up
on the duct gently until it snaps into place.
4. Reconnect the electrical connectors.
5. Install the engine cover extension by gently squeezing
the sides and sliding
it into place. Make sure all of the
fastener clips engage, and the extension fits properly
in place. Replace and tighten the two screws.
5. Install the two nuts to secure the extension in place.
Air Cleaner
"""""".
To remove the air filter, lift the hood, unsnap both clips
and remove the top. After changing the filter, snap both
clips
to secure the air cleaner. Be sure the air cleaner lid
is correctly positioned to seal
out dust and contaminants
that are harmful to your engine.
Make sure the fresh air hose
is still attached after the
filter change.

rire Chains
NOTICE:
If your vehicle has P235/65R15 size tires, don’t
use tire chains. They can damage your vehicle.
If you have other size tires, use tire chains only
where legal and only when you must.
Use only
SAE Class “S” type chains that are the proper size
for your tires. Install them on the
rear axle tires
and tighten them as tightly as possible with the
ends securely fastened. Drive slowly and follow
the chain manufacturer’s instructions.
If you can
hear the chains contacting your vehicle, stop and
retighten them.
If the contact continues, slow down
until it stops.
Driving too fast or spinning the
wheels with chains on
will damage your vehicle.
Appearance Care
Remember, cleaning products can be hazardous. Some
are toxic. Others can burst into flame if you strike a
match or get them
on a hot part of the vehicle. Some are
dangerous
if you breathe their fumes in a closed space.
When you use anything from a container to clean your
vehicle, be sure to follow
the manufacturer’s warnings
and instructions. And always open your doors or
windows when you’re cleaning the inside.
Never use these to clean your vehicle:
Gasoline
Benzene
0 Naphtha
0 Carbon Tetrachloride
Acetone
Paint Thinner
Turpentine
Lacquer Thinner
Nail Polish Remover
They can all be hazardous
-- some more than
others
-- and they can all damage your vehicle, too.
