Most people simply leave the overdrive function "on" all the time. However, you may want to dis-engage it if operating under rough terrain conditions or in rough weather (ice & snow) conditions, or when pulling or towing something. Some people leave it dis-engaged if they do a lot of constant driving in the 35 to 45 mph range to keep it from "hunting" back and forth between high gear and overdrive.

No, not all Honda Elements have drive chains. The Honda Element, which was produced from 2003 to 2011, primarily features a front-wheel-drive system or an optional all-wheel-drive system, utilizing a conventional drivetrain rather than a chain drive. Most Honda Elements are equipped with a traditional transmission that connects the engine to the wheels through gears.
