Cost of a 90K service including cost to replace water pump and 12v battery on 2007 Toyota Highlander Hybrid

I am being quoted $2300 to do a 90K service with replacement of timing belt and water pump. This seems very high. Is it standard to replace timing belt at 90K?

The price of a 90,000 service on your Hybrid Highlander at our dealership is $610.55. The timing belt is required to be replaced at this interval by the manufacturer. In regard to water pump we would inspect it while replacing the timing belt. If it also required replacement it would cost $308.54 to do it at the same time.
