Downloaded from www.Manualslib.com manuals search engine When to Add Oil
If the oil is at or below the ADD line. 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
crankcase capacity, see "Capacities and Specifications"
in the Index.
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.
Be sure to fill it enough to put the level somewhere in
the proper operating range. Push the dipstick all the way
back
in when you're through.
What Kind of Oil to Use
Oils recommended for your vehicle can be identified by
looking for the "Starburst" symbol. This symbol
indicates that
the oil has been certified by the American
Petroleunl Institute
(API). Do not use any oil which
does not carry
this Starburst symbol.
If you change your own oil. be sure you use oil that has
the Starburst symbol
on the front of the oil container. If
you have your oil changed for you, be sure the oil put
into your engine is American Petroleum Institute
certified for gasoline engines.
You should
also use the proper viscosity oil for your
vehicle. as
shown in the following chart:

to advise if you think something should be added.
When to Change Engine Oil
If any one of these is true for you. use the short tripkity
. maintenance schedule:
a
a
a
0
a
Most trips are less than 5 to 10 miles (8 to 16 km).
This is particularly important when outside
temperatures are below freezing.
Most trips include extensive idling (such
as frequent
driving in stop-and-go traffic).
You operate
your vehicle in dusty areas or
off-road frequently.
You frequently tow
a trailer or use a currier on top of
your vehicle.
The vehicle is used for delivery service. police, taxi
or other commercial application. Driving under
these conditions causes engine oil
to
break down sooner. If any one of these is true for your
vehicle, then you need
to change your oil and filter
every
3.000 miles (5 000 km) or 3 months -- whichever
occllrs first.
If none of them is true, use the long trip/highway
maintenance schedule. Change the oil and filter every
7,500 miles ( 12 500 km) or 12 months -- whichever
occurs first. Driving
a vehicle with a fully warmed
engine under highway conditions causes engine oil
to
break down slower.
Remote Oil Filter (Four-wheel Drive)
The access door for the remote oil filter is in the steering
linkage shield assembly located under the radiator
support.
Twist the screw to unlock or lock the door.
Make sure
if you open the door. it is securely closed
when
~OLI are finished.

Downloaded from www.Manualslib.com manuals search engine 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.)
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.
Air Cleaner
cr
To remove the air cleaner, remove the wing nuts that
hold
the cover on. Remove the cover and lift out the
air filter.
Insert
a new air filter, then replace the air cleaner cover.
Tighten the wing
nuts to hold the cover in place.

Operating the engine with the air cleaner off can
cause you or others to be burned. The air cleaner
not only cleans the
air, it stops flame if the engine
backfires.
If it isn’t there, and the engine
backfires, you could be burned. Don’t drive with
it
off, and be careful working on the engine with
the air cleaner
off.
NOTICE:
If the air cleaner is off, a backfire can cause a
damaging engine fire. And, dirt can easily get
into your engine, which will damage
it. Always
have the air cleaner in place when you’re driving.

(53 000 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.

vehicle
is parked on a level place and the transmission is
cool enough for
you to rest your fingers on the
transmission case.
