Chrysler 2004 300M - Manual (Page 161)

PARKING BRAKE
When the parking brake is applied with the ignition on,
the red Brake light in the instrument cluster will come on.
NOTE: This light only shows that the parking brake is
applied. It does not show the degree of brake application.
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 the release lever
located on the lower edge of the instrument panel.
When parking on a hill, you must set the parking brake
before
placing the gear selector in Park. If you don’t, 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 an uphill
grade.
The parking brake should always be applied when the
driver is not in the vehicle.
