Pontiac 2009 G8 Owner's Manual page 289

The jump start positive (A) and
negative posts (B) are located in the
engine compartment on the driver
side of the vehicle.
These posts are used instead of a
direct connection to the battery.
Vehicle Service and Care
The positive jump start connection
is covered by a red cap. Remove to
expose the terminal.
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. Position the two vehicles so that
they are not touching.
3. Set the parking brake firmly and
put the shift lever in P (Park).
See Shifting Into Park (Automatic
Transmission) on page 8-12.
