warning flashers if needed.
{Warning
An electric fan 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.
{Warning
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.
Battery fluid contains acid
that can burn you. Do not
get it on you. If you

eyes or on your skin, flush
the place with water and get
medical help immediately.

moving parts once the
engine is running.
5. Connect one end of the red positive (+) cable to the
remote positive (+)
terminal on the discharged
battery.
6. Connect the other end of the red positive (+) cable to
the positive (+) terminal of
the good battery.
7. Connect one end of the black negative (–) cable to
the negative (–) terminal of
the good battery. 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.
8. Connect the other end of the black negative (–) cable
to the negative (–)
grounding point for the
discharged battery.
9. Start the engine in the vehicle with the good
battery and run the engine
at idle speed for at least
four minutes.
10. Try to start the vehicle that had the dead battery.
If it will not start after a
few tries, it probably needs
service.

when removing the jumper
cables.

Potential Issues

Global Positioning
System (GPS)
.Obstruction of the GPS can
occur in a large city with tall
buildings; in parking garages;
around airports; in tunnels
and underpasses; or in an
area with very dense trees.
If GPS signals are not
available, the OnStar system
should still operate to callOnStar. However, OnStar
could have difficulty
identifying the exact
location.
.In emergency situations,
OnStar can use the last
stored GPS location to send
to emergency responders.
A temporary loss of GPS can
cause loss of the ability to
send a Turn-by-Turn
Navigation route. The Advisor
may give a verbal route or may
ask for a call back after the
vehicle is driven into an
open area.
Cellular and GPS
Antennas
Cellular reception is required
for OnStar to send remote
signals to the vehicle. Do not
place items over or near the
antenna to prevent blocking
cellular and GPS signal
reception.
