Jump Starting - Chevrolet 2005 T-Series Owner's Manual

Jump Starting

If your batteries have run down, you may want to use
another vehicle and some jumper cables to start
your vehicle. Be sure to 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 the other vehicle. It must have a 12-volt
battery (or batteries) 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.
In diesel engine vehicles with two batteries
(or more), you may not be able to get enough
power from a single battery in another vehicle to
start your diesel engine, especially in cold weather.
If your vehicle has more than one battery, use
the one closest to the starter — this will reduce
electrical resistance.
2. Get the vehicles close enough so the jumper cables
can reach, but be sure the vehicles are not touching
each other. If they are, it could cause a ground
connection you do not want. You would not be able
to start your vehicle, and the bad grounding
could damage the electrical systems.
To avoid the possibility of the vehicles rolling, set
the parking brake firmly on both vehicles involved in
the jump start procedure. Put an automatic
transmission in PARK (P) or a manual transmission
in NEUTRAL before setting the parking brake.
