1997 CHEVROLET SUBURBAN battery

Theft-Deterrent Feature
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.
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 is removed. If your battery loses power for any
reason, you must unlock the radio with the secret code
before it will operate.
Activating the Theft-Deterrent Feature
The instructions which follow, explain how to enter your
secret code to activate the THEFTLOCK system. It is
recommended that you read through all nine steps
before starting the procedure.
NOTE: If you allow more than
15 seconds to elapse
between any steps, the radio automatically reverts to
time and you must
start the procedure over at Step 4.

You can run the engine to keep warm, but be careful.

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 awhile.
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.

Other Warning Devices
If you carry reflective triangles, you can set one up at
the side of the road about
300 feet (100 m) behind
your vehicle.
Jump Starting
If your battery (or batteries) has run down, you may
want to
use another vehicle and some jumper cables to
start your vehicle. But please use the following steps to
do it safely.
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.
NOTICE:
Ignoring these steps could result in costly damage
to your vehicle that wouldn’t be covered
by your
vehicle warranty.
Trying to start your vehicle by pushing
or pulling
it could damage your vehicle. With an automatic
transmission, it won’t start that
way.
1. Check the other vehicle. It must have a 12-volt
battery with a negative ground system.
2. Get the vehicles close enough
so the jumper cables
can reach, but be sure the vehicle’s 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
fiiy on both vehicles involved in the
jump
start procedure. Put an automatic transmission
in
PARK (P). If you have a four-wheel-drive vehicle,
be sure the transfer case is not
in NEUTRAL (N).

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, and radios. This will avoid sparks
and help save both batteries. And
it could save
your radio!
NOTICE:
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.
~ If your vehicle has air conditioning, the auxiliary
electric fan under the hood can start up even
when the engine is not running and can injure
you. Keep hands, clothing and tools
away from
any underhood electric fan.
I
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 Delco 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 negative (-)
or 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.

1 A
CAUTION:
--
Fans or other moving engine parts can injure you
badly. Keep your hands away from moving parts
once the engines are running.
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.
8. Now connect the black
negative
(-) cable to
the good battery’s
negative
(-) cable.
Don’t let the other end touch anything until the next
step. The other end
of the negative (-) cable doesn’t go
to the dead battery. It goes to a heavy unpainted metal
part of the vehicle with the dead battery.
ProCarManuals.com

9. Attach the cable at least 18 inches (45 cm) away
from the dead battery, but not near engine parts that
move. The electrical connection is just as good
there, but the chance
of sparks getting back to the
battery is much less.
10. Now start the vehicle with the good battery and run
the engine for a while.
11. Try to start the vehicle with the dead battery.
If it
won’t start after a few tries, it probably needs service. 12.
Remove the cables in reverse order to prevent
electrical shorting. Take care that they don’t touch
each other or any other metal.
