Turn
off the engine and give
the oil
a few minutes to drain
back into the
oil pan. If you
don’t, the oil dipstick might
not show the actual level.
Checking Engine Oil
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.
When to Add Oil
If the oil is at or below the ADD mark, then ~011’11 need to

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 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
occurs first.
If none of them is true, change the oil and filter every
7,500 miles (1 2 SO0 km) or 12 months -- whichever
occurs first. Driving a vehicle
with a fully warnled
engine under highway conditions causes engine oil to
break down slower.
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:
Rust or dirt on a wheel, or on the parts to which
it is fastened, can make wheel nuts 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.) When
It’s Time for New Tires
One way
to tell when it’s
time for new tires
is to
check the treadwear
indicators, which will
appear when your tires have
only 1/16 inch (1.6 mm) or
less of tread remaining.
Some commercial truck
tires may
not have
treadwear indicators.
You need a new tire if any of the following statements
are true:
0 You can see the indicators at three or more places
0 You can see cord or fabric showing through the
tire’s rubber.
0 The tread or sidewall is cracked, cut or snagged deep
enough to
show cord or fdbric.
0 The tire has a bump, bulge or split.
The tire has a puncture, cut or other damage that
around the
tire.

Cleaning the Inside of Your Vehicle
Use a vacuum cleaner often to get rid of dust and loose
dirt. Wipe vinyl or leather
with a clean, damp cloth.
Your
CM dealer has two GM cleaners, a solvent-type
spot lifter and a foam-type powdered cleaner. They will
clean normal spots and stains very well. Do
not use
them on
vinyl or leather.
Here are some cleaning tips:
Always read the instructions on the cleaner label.
Clean up stains as soon as you can -- before they set.
Use a clean cloth or sponge, and change to a clean area
often. A soft brush may be used
if stains are stubborn.
Use solvent-type cleaners in a well-ventilated area
only.
If you use them, don’t saturate the stained area.
If a ring forms after spot cleaning, clean the entire
area immediately or
it will set.
