There is a Nissan Quest family van that has been sitting in our garage for more than 5 years. We just didn't need to use the van anymore, and just left it in the garage. It hasn't been used in all this time. I want to use it now. The battery is dead and the tires have deflated. What else will be wrong with it?

Can I just jump start it and refill the air in it? Will be calling triple A (insurance) tomorrow to come jump start it, but it may have other problems. What can I expect?

Thanks
