Honda is suspending May orders for Japan-made vehicles from U.S. dealers following the earthquake and tsunami in Japan.

The carmaker told Honda and Acura dealers an e-mail Thursday vehicles produced in May might be needed to fill existing orders that have been delayed due to the disruption. Typically, dealers order cars six weeks in advance.

Honda Motor Co. said Friday it expects to resume production in Japan on Wednesday. But it said in the e-mail that it can't guarantee when production will return to full capacity.

More than 80 percent of Honda and Acura vehicles sold in the U.S. are made in North America. Models sold in North America but made in Japan are the Fit, CR-Z, Civic Hybrid, Insight, Acura TSX, Acura RL and a small number of CR-Vs.
