5. Find the positive (+) and negative (-) terminals on
each battery
or remote terminal. You should always
use the remote positive
(+) terminal instead of the
positive
(+) terminal on your battery.
To open the remote positive (+) terminal box, pull
the tab and open the cover.
r
6. Check that the jumper cables don’t have loose or
missing insulation.
If they do, you could get a shock.
The vehicles could be damaged too.
Before you connect the cables, here are some things
you should know. Positive
(+) will go to positive (+)
and negative (-) will go to a metal engine part. Don’t
connect positive
(+) to negative (-) or you’ll get a
short that would damage the battery and maybe other
parts too.
Using
a match near a battery can cause battery
gas to explode. People have been hurt doing this,
and some have been blinded. Use
a flashlight if
you need more light.
Be sure the battery has enough water.
You don’t need
to add water to the ACDelco Freedom@ battery
installed
in every new GM vehicle. But if a battery
has fder caps, be sure the right amount
of fluid is
there.
If it is low, add water to take care of that first. If
you don’t, explosive gas could be present.
Battery fluid contains acid that can burn you.
Don’t get it on you.
If you accidentally get it in
your eyes or on your skin, flush the place with
water and get medical help immediately.
A CAUTION:
Fans or other moving engine parts can injure you
badly. Keep your hands away from moving parts
once the engine is running.

NOTICE:
If you need a new cap, be sure to get the right
type. Your retailer can get one for you.
If you get
the wrong type, it may not fit properly. This may
cause your malfunction indicator lamp to light
and your fuel tank and emissions system may be
damaged. See “Malfunction Indicator Lamp” in
the Index.
FYng a Portable Fuel Container
I-
Never fill a portable fuel container while it is in
your vehicle. Static electricity discharge from the
container can ignite the gasoline vapor. You can
be badly burned and your vehicle damaged if
this
occurs. To help avoid injury to you and others:
Dispense gasoline only into approved
containers.
CAUTION: (Continued)
I
!
Do not fill a container while it is inside a
vehicle, in a vehicle’s trunk, pickup bed or
on any surface other than the ground.
inside of the fill opening before operating
the nozzle. Contact should be maintained
until the filling is complete.
Bring the fill nozzle in contact with the
Don’t smoke while pumping gasoline.
Checking Things Under the Hood
An electric fan under the hood can start up and
injure you even when the engine is not running.
Keep hands, clothing and tools away from any
underhood electric fan.

OIL
If the CHECK OIL LEVEL
message
or the oil warning
light
on the instrument
panel comes on, it means
you need to check your
engine oil level right away.
For more information, see “Check Oil Level Message”
or “Oil Pressure Warning Light” in the Index. You
should check your engine oil level regularly; this
is
an added reminder.
It’s a good idea to check your engine oil every time you
get fuel. In order to get an accurate reading, the 02 must
be warm and the vehicle must be on level ground.
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 Engine 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.
