From the owner's manual:

"Do not allow the engine to warm up by leaving it running while the vehicle remains stationary. Instead, begin to drive at a moderate engine speed."

Driving the car right away allows everything to warm up and reach optimal conditions quicker. As others have said, it's good to take it easy until everything is warmed up.
