About 30 psi front (not 34 as the mistake in the handbook says),and about 33 to 38 on the back, depending on load. Should be a label on the driver's door frame.

why is 34 a mistake? and why so low compared to the back? and why the big difference between the front and back?

The front and rear wheels do different jobs, and 33 psi would be for no passengers, and 38 would be for a fully loaded car.

Because it also says 2.1 bar (correct) and 2.1 bar is about 30 psi, not 34 psi.
