I can't make them out either...
It looks like the date is 03/03/31 - March 31st, 2003 but that's my interpretation. If that's the case then that was 10 years ago and my personal opinion would be to change the timing gear - belt, two pulleys, water pump and hydraulic tensioner pulley. The crank and both cam seals are usually changed at this time and thus an oil and oil filter change is also done. The thermostat and gasket are also checked for any defects. You should also change your engine coolant if it is dirty.
Your mechanic should tell you exactly what is required to do all of this work.
