I thought it was 29/32 or something like that. Check the sticker in the driver's side door jamb. The pressure is for OEM-sized P-rated radial tires. Note that LT tires require much higher pressures. Regardless, I inflate my stock tires to 32-33psi front/rear. I find I get good fuel economy and even wear at these pressures. Keep in mind that during the winter, you have to inflate often since a sudden drops in temps can cause your tire pressure to really drop. I find I have to check every month as the weather gets colder, but in the spring, as it warms, the pressure increases with temp, so don't have to inflate as often. Pick a day w/ low humidity to inflate. This will result in less moisture inside the tire, less temp fluctuation, and only helps the rubber life as tires degrade internally due to moisture.

IMO-the numbers on the door give you the 'smoothest' ride, but running 33-36# all around improves mileage and tires last longer...I add 3-4#s...the sticker recs F29 & R32...I run ~F33 & R35 and this seems to give me the best trade-off...(at least that's what I start out with)...probably leaks down a little every week or 2)...34-35#s all around makes it simple...
