If the car starts from cold OK, then just drive away normally. There's no need for warmup. The car will warm up faster by being driven than by idling. As pointed out, the cold start injector was eliminated. Instead, the fuel management system runs the 4 injectors slightly rich on cold starts.

In my case, I avoid heavy throttle or high RPM (pretty much always come to think of it) but certainly until the engine has warmed up.

Best thing you can do to reduce wear and tear on your engine is regular (see owners book) oil and filter changes with top quality 5W30 or 10W30 oil. That and a clean air filter and maybe throw in a fresh set of spark plugs (NGK BPR6ES).
