Jump Starting - GMC 2007 Sierra 1500 Pickup Owner's Manual

Jump Starting

If your vehicle's battery (or batteries) has 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 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.
2. If you have a vehicle with a diesel engine
with two batteries (or more), you should
know before you begin that, especially in cold
weather, you may not be able to get enough
power from a single battery in another vehicle
to start your diesel engine.
If your vehicle has more than one battery, use
the battery that is closer to the starter — this
will reduce electrical resistance.
