I need a maintenance manual for the obvious reasons. I was delighted to find one on line here at the KIA Forums. I have a 2002 KIA Rio base model. It is a great auto. The trans-axle began acting out. I acquired . I installed a bearing kit side gears and spiders. It worked out very well. The car needs help still so I paid for the pdf to have the trouble shooting guide which has not been very helpful. I receive error message, "Windows does not support this format." and "Windows cannot open this file." The problem impedes any progress, attempts to effect repairs is not very fruitful. I need assistance with a workable, usable manual. Any assistance would be greatly appreciated . Thank You.
