Jump Starting - GMC 1999 Suburban Owner's Manual

Jump Starting

If your battery (or batteries) has run down, you may
want to use another vehicle and some jumper cables to
start your vehicle. But please use the following steps to
do it safely.
CAUTION:
Batteries can hurt you. They can be dangerous
because:
D
They contain acid that can burn you.
D
They contain gas that can explode or ignite.
D
They contain enough electricity to
burn you.
If you don't 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 wouldn't be covered by
your warranty.
The ACDelco Freedom R battery in your vehicle
has a built-in hydrometer. Do not charge, test or
jump start the battery if the hydrometer looks
clear or light yellow. Replace the battery when
there is a clear or light yellow hydrometer and a
cranking complaint.
Trying to start your vehicle by pushing or pulling
it won't work, and it could damage your vehicle.
1. Check the other vehicle. It must have a 12
battery with a negative ground system.
NOTICE:
If the other system isn't a 12
negative ground, both vehicles can be damaged.
