vehicle. However,
you can use SAE 5W-30 if it’s going
to be colder than
60°F ( 16” C) before your next oil
change. When it’s very cold, you should use
SAE
5W-30. These numbers on an oil container show its

Do not use other viscosity oils,
such as
SAE 2OW-50.
Engine Oil Additives
Don’t add anything to your oil. Your Catera dealer is
ready 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:
NOTICE:

If you are in an area where the temperature falls below
-20°F (-29”C), consider using either an SAE 5W-30
synthetic oil or an
SAE OW-30 oil. Both will provide
easier cold starting and better protection for your engine
at extremely low temperatures.

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).
Most trips are through dusty areas.
You frequently tow a trailer or use a carrier on top
of your Catera.
The vehicle is used for delivery service, police, taxi

Downloaded from www.Manualslib.com manuals search engine 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
5,000 miles (8 000 km) or 3 months -- whichever
occurs first. (See “Check Oil Light” in the Index.)
If none of them is true, use the long triphighway
maintenance schedule. Change the oil and filter at the
first
5,000 miles (8 000 km) or 3 months -- whichever
occurs first. Then, change the oil and filter every
10,000 miles
( 16 000 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. (See “Check Oil Light”
in
the Index.)
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.

A CAUTION:
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 flames
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

soon as possible. You may also have your fluid level
checked by your dealer or service center when
you have
your
oil changed.

Your new Catera comes with high-quality tires made by
a leading tire manufacturer. If you ever have questions
about your tire warranty and where
to obtain service, see
your Catera Warranty booklet for details.
I
/! CAUTION:
Poorly maintained and improperly used tires
are dangerous.
0 Overloading your tires can cause overheating
as a result of too much friction. You could
have an airout and
a serious accident. See
“Loading Your Vehicle” in the Index.
0 Underinflated tires pose the same danger as
overloaded tires. The resulting accident
could cause serious injury. Check all tires
frequently to maintain the recommended
pressure. Tire pressure should be checked
when your tires are cold.
CAUTION: (Continued)
I--
@ Overinflated tires are more likely to be
cut, punctured or broken
by a sudden
impact
-- such as when you hit a pothole.
Keep tires at the recommended pressure.
0 Worn, old tires can cause accidents. If your
tread is badly worn, or
if your tires have
been damaged, replace them.
See “Inflation
-- Tire Pressure” in this section
for inflation pressure adjustment for higher
speed driving.
Inflation -- Tire Pressure
The Tire-Loading Information label, which is located

Downloaded from www.Manualslib.com manuals search engine Tire Inspection and Rotation
Tires should be rotated at 5,000 miles (8 000 km) and
then every
10,000 miles ( 16 000 km) thereafter. Any
time you notice unusual wear, rotate your tires as soon
as possible and check wheel alignment.
Also check for
damaged tires or wheels.
See “When It’s Time for New
Tires” and “Wheel Replacement” later in this section for
more information.
The purpose of regular rotation is to achieve more
uniform
wear for all tires on the vehicle. The first
rotation is the most important. See “Scheduled
Maintenance Services’’ in the Maintenance Schedule
booklet for scheduled rotation intervals. When rotating your tires,
always use the correct
rotation pattern shown here.
After the tires have been rotated, adjust the front
and rear inflation pressures as shown on the
Tire-Loading Information label. Make certain that all wheel bolts are properly tightened. See “Wheel Bolt
Torque”
in the Index.
Rust or dirt on a wheel, or on the parts to which
it is fastened, can make wheel studs become loose
after a time. The wheel could come off and cause
an accident. When you change
a wheel, remove
any rust or dirt from places where the wheel
attaches to the vehicle. In an emergency, you can
use a cloth or a paper towel to do this; but be
sure to use a scraper or wire brush later, if you
need to, to get all the rust or dirt off. (See
’ “Changing a Flat Tire” in the Index.)
