1998 GMC SAVANA battery

Voltmeter
When your engine is not
on (in the
RUN position),
this gage shows your
DC volts.
I I / /I, running, but the ignition is
9 19 battery's state of charge in
VOLTS I
W
When the engine is running, the gage shows the
condition
of the charging system. Readings between the
low and high warning zones indicate the normal
operating range. Readings
in the low warning zone may occur wnen a
large number
of electrical accessories are operating in
the vehicle and the engine is left at an idle for
an
extended period. This condition is normal since the
charging system is not able to provide full power at
engine idle.
As engine speeds are increased, this
condition should correct itself as higher engine speeds
allow the charging system to create maximum power.
You can only drive for
a short time with the reading in
either warning zone.
If you must drive, turn off all
unnecessary accessories.
Readings in either warning zone indicate
a possible
problem in the electrical system. Have the vehicle
serviced as soon as possible.

Theft-Deterrent Feature (If Equipped)
THEFTLOCK@ is designed to discourage theft of your
radio. It works by using a secret code
to disable all radio
functions whenever battery power is removed. Your
audio system is equipped with THEFTLOCK if
THEFTLOCK is displayed on the front of the radio.
The THEFTLOCK feature for the radio may be used or
ignored. If ignored, the system plays normally and the
radio is not protected by the feature.
If THEFTLOCK is
activated, your radio will not operate if stolen.
When THEFTLOCK is activated, the radio will display
LOC to indicate a locked condition anytime battery
power has been interrupted. If your battery loses power
for any reason, you must unlock the radio with the secret
code before it will operate.

If you enter the wrong code eight times, INOP will
appear on the display. You will have to wait an hour
with
the ignition on before you can try again. When you
try again, you will only have three chances to enter the
correct code before INOP appears.
If
you lose or forget your code, contact your dealer.
Disabline the Theft-Deterrent Feature
Enter your secret code as follows; pause no more than
15 seconds between steps: If
the code entered is incorrect, SEC will appear on the
display. The radio will remain secured until the correct
code is entered.
When battery power is removed and later applied to a
secured radio, the radio won’t turn on and LOC will
appear
on the display.
To unlock a secured radio, see “Unlocking the
Theft-Deterrent Feature After a Power
Loss” earlier

Understanding Radio Reception
AM
The range for most AM stations is greater than for FM,
especially at night. The longer range, however, can
cause stations to interfere with each other.
AM can pick
up noise from things like storms and power
lines. Try
reducing the treble
to reduce this noise if you ever get it.
FM Stereo
FM stereo will give you the best sound, but FM signals
will reach only about
10 to 40 miles (16 to 65 km). Tall
buildings or hills can interfere with FM signals, causing
the sound to come and go.

Snow can trap exhaust gases under your vehicle.
This can cause deadly
CO (carbon monoxide) gas
to get inside.
CO could overcome you and kill
you. You can’t see it or smell it, so you might not
know it is in your vehicle. Clear away snow from
around the base
of your vehicle, especially any
that is blocking your exhaust pipe. And check
around again
from time to time to be sure snow
doesn’t collect there.
Open
a window just a little on the side of the
vehicle that’s away
from the wind. This will help
keep
CO out.
Run your engine only as long as you must. This saves
fuel. When you run the engine, make it go a little faster
than just idle. That is, push
the accelerator slightly. This
uses less fuel for the heat that
you get and it keeps the
battery (or batteries) charged.
You will need a
well-charged battery (or batteries) to restart the vehicle,
and possibly for signaling later on with your headlamps.
Let the heater
run for a while.
If
you have a diesel engine, you may have to run it at a
higher speed to get enough heat. Then, shut the engine
off and close the window almost all the way to preserve
the heat. Start the engine again and repeat this only
when you feel really uncomfortable from the cold. But
do
it as little as possible. Preserve the fuel as long as you
can.
To help keep warm, you can get out of the vehicle
and do some fairly vigorous exercises every half hour or
so until help comes.

. ~p Starting
lr your battery has run down, you may want to use
another vehicle and some jumper cables to start your
vehicle. But please follow the steps below
to do it safely.
i A CAUTION:
Batteries can hurt you. They can be dangerous
because:
0 They contain acid that can burn you.
0 They contain gas that can explode or ignite.
0 They contain enough electricity to burn you.
If you don’t follow these steps exactly, some or all
of these things can hurt you.
I NOTICE:
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
it 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.
1 NOTICE:
If the other system isn’t a 12-volt system with a
negative ground, both vehicles can be damaged.

If you have a diesel engine vehicle with two batteries
(or more) you should know before you begin that,
especially
in cold weather, you may not be able to
get enough power from
a single battery in another
vehicle to start your diesel engine.
If your vehicle has more than one battery, use the
battery that is under the hood
of the vehicle - this
will reduce the electrical resistance.
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 your automatic
transmission
in PARK (P).
3. Turn off the ignition on both vehicles. Turn off all
lamps that aren’t needed,
and radios. This will avoid
sparks and help save both batteries, and could save
your radio.
NOTICE: -1
If you leave your radio on, it could be badly
damaged. The repairs would not be covered by
your warranty.

4. Open the hoods and locate the batteries. Find the
positive
(+) and negative (-) terminals on each battery.
An electric fan can start up even when the engme
is not running and can injure you. Keep hands, clothing and tools away from any underhood
electric fan.

A CAUTION:
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 batteries have enough water. You
don’t need to add water to the ACDelco
Freedom@ battery (or batteries) installed in
every new
GM 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. 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
(+) and negative (-) will go to an unpainted
metal engine part or
a body metal surface. Don’t
connect positive
(+) to negative (-) or you will get a
short that would damage the battery and maybe other
parts, too. And don’t connect the negative
(-) to
negative
(-).
Fans or other moving engine parts can injure you
badly. Keep your hands
away from moving parts
once the engine is running.

6. Connect the red positive (+) cable to the positive (+)
terminal of the vehicle with the dead battery. Or 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.
8. Now connect the black
negative
(-) cable to the
good battery’s
negative
(-) terminal.
Don’t let the other end
touch anything until the
next step.
