Bro waisay according to new thoughts running is not required for these new engines. But I did myself upto 1000 KM. Probably, no harm in switching to sports mode but that is not beneficial if you are following running rule.
First Oil change will be due @ 5000 Km by the company. No Oil change due at 1000 KM.
But if you opt Oil change from outside other than company then your warranty will be voided. So to keep warranty intact it is necessary to follow maintenance schedule of Kia Motors...
Thanks.
