dead battery GMC SIERRA CLASSIC 2007 Owners Manual

You can run the engine to keep warm, but be
careful.
{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 cannot 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 does not collect there.
Open a window just a little on the side of
the vehicle that is 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.

{CAUTION:
Fans or other moving engine parts can
injure you badly. Keep your hands away
from moving parts once the engine is
running.
6. Check that the jumper cables do not 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 a remote positive
terminal (+) if the vehicle has one. Negative (−)
will go to a heavy, unpainted metal engine
part or a remote negative (−) terminal if
the vehicle has one.Do not connect positive (+) to negative (−)or
you will get a short that would damage
the battery and maybe other parts too. And
do not connect the negative (−) cable to
the negative (−) terminal on the dead battery
because this can cause sparks.
On vehicles that have dual batteries, make all
battery connections to the remote positive (+)
and remote negative (−) terminals.
7. 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.

8. Do not 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.
9. Now connect the black negative (−) cable to
the negative (−) terminal of the good battery.
Use a remote negative (−) terminal if the
vehicle has one. The vehicle’s remote
negative (–) terminal is marked GND.
10. Do not let the other end touch anything until the
next step. The other end of the negative (−)
cable does not go to the dead battery. It goes
to a heavy unpainted metal engine part of the
vehicle with the dead battery, or to a remote
negative (–) terminal if the vehicle has one.11. Connect the
other end of the
negative (−) cable
to the remote
negative (−) terminal,
marked GND, on the
vehicle with the dead
battery.
SeeEngine Compartment Overview on
page 480for the location of your vehicle’s
remote negative (−) terminal.
12. Now start the vehicle with the good battery
and run the engine for a while.
13. Try to start the vehicle that had the dead
battery. If it will not start after a few tries, it
probably needs service.

Notice:If the jumper cables are connected or
removed in the wrong order, electrical shorting
may occur and damage the vehicle. The repairs
would not be covered by your warranty. Always
connect and remove the jumper cables in the
correct order, making sure that the cables do
not touch each other or other metal.
A. Heavy, Unpainted Metal Engine Part or
Remote Negative (−) Terminal
B. Good Battery or Remote Positive (+) and
Remote Negative (−) Terminals
C. Dead Battery or Remote Positive (+) TerminalTo disconnect the jumper cables from both
vehicles do the following:
1. Disconnect the black negative (−) cable from
the vehicle that had the bad battery.
2. Disconnect the black negative (−) cable from
the vehicle with the good battery.
3. Disconnect the red positive (+) cable from the
vehicle with the good battery.
4. Disconnect the red positive (+) cable from the
other vehicle.
5. Return the remote positive (+) terminal cover,
if your vehicle has one, to its original position.
