A day before he unveils his plans for the U.S. auto industry, President Barack Obama said car makers, unions and creditors will have to make sacrifices to weather the economic slump and emerge "lean and mean."

"They're not quite there yet," Obama told CBS News's Face the Nation.

With a Tuesday deadline looming for General Motors Corp. GM) and Chrysler LLC (C.XX) to show that they are on the road to viability, Obama will make an announcement on the industry Monday morning. GM and Chrysler, which took $17.4 billion in government assistance late last year, have asked for another $22 billion. Obama didn't say if the request will be granted, but has hinted that he's willing to give further help to the firms in exchange for significant sacrifices.

"What we're trying to let them know is that we want to have a successful auto industry, U.S. auto industry. We think we can have a successful U.S. auto industry, but it's got to be one that is realistically designed to weather this storm and to emerge at the other end much more lean, mean and competitive that it currently is," Obama told CBS.

"And that's going to mean a set of sacrifices from all parties involved - management, labor, shareholders, creditors, suppliers, dealers. Everybody's going to have to come to the table and say it's important for us to take serious restructuring steps now in order to reserve a brigther future down the road.

"They're not there yet," Obama repeated.
