Chrysler 2004 300M - Manual (Page 190)

Remote jump starting terminals are located in the
engine compartment. Check the Battery Test Indicator. If a light or bright
colored dot is visible in the indicator, DO NOT jump-start
the battery.
If the indicator is dark or shows a green dot, proceed as
follows:
1. Wear eye protection and remove any metal jewelry
such as watch bands or bracelets that might make an
inadvertent electrical contact.
2. When boost is provided by a battery in another
vehicle, park that vehicle within booster cable reach but
without letting the vehicles touch. Set parking brake,
place automatic transaxle in PARK, and turn ignition to
OFF for both vehicles.
