service maintenance ...

My friends car is at 407 50 thousand km. Oil change has arrived. However, what should I change? I would be glad if you inform me ... I don't want to do anything wrong or eat a pile.

Oil change or completion, Oil filter change should be made.
Air filter change and Pollen filter change should be done.
Antifreeze and water deficiency should be completed. Those who lose their features and those who come to change should definitely be replaced.
Other necessary general checks are made, together with the beginning of summer summer tires, Rot adjustment should be made. Balance adjustment should be made.

I think how old the vehicle has been 5 years ago, replace the timing belt and v-belt. have the transmission oil checked
