Chrysler 2005 300 - Manual (Page 223)

Before leaving the vehicle, make sure that the parking
brake is fully applied and place the gear selector in the
Park position.
To release the parking brake, pull out on the parking
brake release located on the left side of the instrument
panel.
When parking on a hill, it is important to set the parking
brake before placing the gear selector in Park, otherwise
the load on the transmission locking mechanism may
make it difficult to move the selector out of park. As an
added precaution, turn the front wheels toward the curb
on a downhill grade and away from the curb on a uphill
grade.
