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 - volt
battery with a negative ground system.
NOTICE:
If the other system isn’t a 12 - volt system with a
negative ground, both vehicles can be damaged.
2. Get the vehicles close enough so the jumper cables
can reach, but be sure the vehicles aren’t touching
each other. If they are, it could cause a ground
connection you don’t want. You wouldn’t be able to
start your vehicle, and the bad grounding could
damage the electrical systems.
NOTICE:
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 transaxle in PARK (P).
