2008 CADILLAC ESCALADE ESV dead battery

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 the 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. You will need a
well-charged battery to restart the vehicle, and possibly
for signaling later on with the headlamps. Let the
heater run for a while.

5. 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 to a remote positive (+) terminal if
the vehicle has one. Negative ( − ) will go to a heavy,
unpainted metal engine part or to a remote
negative ( − ) terminal if the vehicle has one.
Do not connect positive (+) to negative ( − )oryou
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.
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. 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.
8. Now connect the black negative ( − ) cable to the
negative ( − ) terminal of the good battery. Use a
remote negative ( − ) terminal if the vehicle has one.
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 or to the remote
negative ( − ) terminal on the vehicle with the dead
battery.
9. Connect the other end of the negative ( − ) cable to
the remote negative ( − ) terminal, on the vehicle with
the dead battery.
10. Now start the vehicle with the good battery and run
the engine for a while.
11. Try to start the vehicle that had the dead battery.
If it will not start after a few tries, it probably
needs service.
