Jump Starting - GMC Hybrid 2006 Owner's Manual

Jump Starting

If your 42-volt battery has run down, you may want to
use another vehicle's 12-volt battery and jumper cables
to start your vehicle. Jump starting your hybrid vehicle
may take considerably longer than a regular vehicle.
You may have to wait 10 to 20 minutes total for
your vehicle to charge from the other vehicle's good
12-volt battery in order to start your vehicle. Use
the following steps to do it safely:
CAUTION:
{
Batteries can hurt you. They can be dangerous
because:
•
They contain acid that can burn you.
•
They contain gas that can explode or
ignite.
•
They contain enough electricity to
burn you.
If you do not 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 would not be covered
by your warranty.
Trying to start your vehicle by pushing or pulling it
will not work, and it could damage your vehicle.
1. Check to see that the battery disconnect switch on
your hybrid vehicle is in the power position. If it is
not, turn it clockwise until it stops and then try
to start your vehicle. See Battery Disconnect Switch
on page 5-20 for more information. If your vehicle
still won't start, continue to Step 2.
2. Check the other vehicle. It must have a 12-volt
battery with a negative ground system.
Notice: If the other vehicle's system is not a 12-volt
system with a negative ground, both vehicles can
be damaged. Only use vehicles with 12-volt systems
with negative grounds to jump start your vehicle.
