1999 GMC SAFARI dead battery

2-55
Your vehicle's engine should be turned off while
programming the transmitter. Follow these steps to
program up to three channels:
1. If you have previously programmed a transmitter
channel, proceed to Step 2. Otherwise, hold
down the two outside buttons on the HomeLink
Transmitter until the indicator light begins to flash
rapidly (after 20 seconds). Then release the buttons.
This procedure initializes the memory and erases any
previous settings for all three channels.
2. Decide which one of the three channels you want
to program. Hold the end of the hand
-held
transmitter about 2 to 5 inches (5 to 13 cm) away
from the surface of the HomeLink Transmitter so
that you can still see the indicator light.
3. Using both hands, press the hand
-held transmitter
button and the desired button on the HomeLink
Transmitter. Continue to press both buttons
through Step 4.
4. Hold down both buttons until you see the red
light on the HomeLink Transmitter flash rapidly.
The rapid flashing indicates that the HomeLink
Transmitter has been programmed. Release both
buttons once the light starts to flash rapidly.If you have trouble programming the HomeLink
Transmitter, make sure that you have followed the
directions exactly as described and that the battery in the
hand
-held transmitter is not dead. If you still cannot
program it, rotate the hand
-held transmitter end over
end and try again. The HomeLink Transmitter may not
work with older garage door openers that do not meet
current Federal Consumer Safety Standards. If you
cannot program the transmitter after repeated attempts,
refer to ªTraining a Garage Door Opener with Rolling
Codesº later in this section or contact the manufacturer
of the unit at 1
-800-355-3515.
Be sure to keep the original hand
-held transmitter
in case you need to erase and reprogram the
HomeLink Transmitter.
Note to Canadian Owners: During programming,
the hand
-held transmitter may automatically stop
transmitting after one or two seconds. In this case, you
should press and re
-press the button on the hand-held
transmitter every two seconds without ever releasing the
button on the HomeLink Transmitter. Release both
buttons when the indicator light on the HomeLink
Transmitter begins to flash rapidly.

CAUTION:
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 charged. You will need a well
-charged battery to
restart the vehicle, and possibly for signaling later on
with your headlamps. Let the heater run for a while.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.
Recreational Vehicle Towing
Your vehicle was not designed to be towed with all four
wheels on the ground. If your vehicle must be towed,
see ªTowing Your Vehicleº in the Index.
NOTICE:
Towing your vehicle with all four wheels on the
ground will damage drivetrain components.

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 a jump
starting stud. Don't connect positive (+) to negative
(
-) or you'll get a short that would damage the
battery and maybe other parts, too.
CAUTION:
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.
7. Don't let the other end
touch metal. Connect
it to the positive (+)
terminal of the
good battery.

5-6
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.
9. The other end of the negative (
-) cable does not go
to the dead battery. It goes to a negative jump
starting stud located near the battery.
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.
