The RealTime AWD System is designed with a pair of pumps, one that's connected to the front wheels and another to the back wheels. Under normal driving conditions, this system powers the front wheels. But when things get slippery, such as driving in inclement weather or on poor road conditions, the front wheels start to spin faster. This system then routes power automatically to the rear wheels to help keep you and your vehicle under control. Honda Genuine Dual Pump Fluid is formulated to work exclusively with the RealTime AWD system.
