Engine Oil
It is important to keep engine oil at the proper level. The engine oil dipstick has a yellow ring and is located
near the center of the engine compartment. See
Engine
information on location.
Checking Engine Oil Compartment Overview on page 5- 14 for more
It’s a good idea to check your engine oil every time
you
get fuel. In order to get an accurate reading, the oil Turn off the engine and give the oil several minutes to

Oil pan. If YOU don’t, the oil dipstick
might not show the actual level.
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.

Replacing Brake System Parts
Te braking system on a vehicle is complex. Its many parts
have to be of top quality and work well together
if the
vehicle is to have really good braking. Your vehicle was
designed and tested with top-quality
GM brake parts.
When you replace parts of your braking system -for
example, when your brake linings wear down and you
need new ones put
in - be sure you get new approved
GM replacement parts. If you don’t, your brakes may no
longer work properly.
For example,
if someone puts in brake linings that are
wrong for your vehicle, the balance between your front
and rear brakes can change -for the worse. The braking
performance you’ve come to expect can change
in many
other ways
if someone puts in the wrong replacement
brake parts.
Battery
Your new vehicle comes with a maintenance free
ACDelco@ battery. When it’s time for a new battery,
get one that has the replacement number shown on the
original battery’s label. We recommend an ACDelco@
battery. See
Engine Compartment Overview on
page 5-74 for battery location.
Warnings Battery posts, terminals and related
accessories contain lead and lead compounds,
chemicals known to the State
of California to cause
cancer and reproductive harm. Wash hands after
handling.

Vehicle Storage
If you’re not going to drive your vehicle for 25 days or
more, remove the black, negative
(-) cable from
the battery. This will help keep your battery from
running down.
Jump Starting
If your battery has run down, you may want to use
another vehicle and some jumper cables to start your
vehicle. But
please follow the numbered steps to
do it safely.
Batteries have acid that can burn you and gas
that can explode. You can be badly hurt if you
aren’t careful. See “Jump Starting” next for
Contact your dealer to learn how
to prepare your
vehicle for longer storage periods.
Also, for your audio system, see Theft-Deterrent
Feature
on page 3-47.

Nofice: Ignoring these steps could result in costly
damage to your vehicle that wouldn’t be covered
by your warranty.
Trying to start your vehicle by pushing or pulling

won’t work, and it could damage your vehicle.

1. Check the other vehicle. It must have a 12-volt
battery with a negative ground system.
Notice: If the other system isn’t a 12-volt system
with a negative ground, both vehicles can be
damaged.
2. Get the vehicles close enough so the jumper cables
can reach, but be sure the vehicles aren’t touching
each other. If they are, it could cause a ground
connection you don’t want. You wouldn’t be able
to
start your vehicle, and the bad grounding could
damage the electrical systems.
To avoid the possibility
of the vehicles rolling, set
the parking brake firmly on both vehicles involved
in the jump start procedure. Put an automatic
transmission in PARK (P) and a manual
transmission in NEUTRAL.
3. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the cigarette
lighter
or accessory power outlets. Turn off all lamps
that aren’t needed as well as radios. This will avoid
sparks and help save both batteries. In addition,
it could save your radio!
Nofice: If you leave your radio on, it could be badly
damaged. The repairs wouldn’t be covered by
your warranty.
4. Open the hoods and locate the batteries. Find the
positive
(+) and negative (-) terminals on each
battery.
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@
battery installed in your new vehicle. But if
a battery has filler 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.
5-48

Fans or other moving engine p-. ts can injure
you badly. Keep your hands away from moving
parts once the engine
is running.
5. 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
basic things you should know. Positive
(+) will go
to positive
(+) or to a remote positive (+) terminal
if the vehicle has one. Negative (-) will go to a
heavy, unpainted metal engine part, or to a
negative
(-) terminal if the vehicle has one.
Don’t connect positive
(+) to negative (-) or you’ll
get a short that would damage the battery and
maybe other parts, too. And don’t connect the
negative
(-) cable to the negative (-) terminal on
the dead battery because this can cause sparks.
6. Connect the red
positive
(+) cable to the
positive
(+) terminal
of the vehicle with the
dead battery.
Use
a remote positive (+)
terminal if the
vehicle has one.
7. Don’t let the other end
touch metal. Connect it
to the positive
(+)
terminal of the good
battery. Use a remote
positive
(+) terminal
if the vehicle has one.
5-49

The other end of the negative (-) cable does not
go to the dead battery. It goes to a heavy,
unpainted metal engine part, or to a remote
negative
(-) terminal on the vehicle with the
dead battery.
Notice: Damage to your vehicle may result from
electrical shorting
if jumper cables are removed
incorrectly. To prevent electrical shorting, take care
that the cables don’t touch each other
or any
other metal. The repairs wouldn’t be covered by
your warranty.
