Does anybody has a proper list of which items should be replaced during the servicing of the Tucson ?
At what service intervals should spark plugs, filters, timing belts etc ?

Many thanks

usually the Owners Manual is the best place to look for this info. there is a service schedule in there towards the back....

you failed to mention how many miles are on the Tuc... is this a 3,000 mile service, or something like a 15k mile service?

In addition, read the info supplementing the list(s) carefully. There is more than one list because service schedules vary according to the driving conditions. Without actually referring to it I think it divides driving conditions into 'normal' and 'adverse' or something like that.
For example, I live in Barbados, the island has about 166 square miles, but our service schedule kinda follows adverse because of the frequent short trips. It may seem counter to your thinking but that is how it goes. More highways....normal conditions. Also they take into consideration the environmental conditions, if it is dusty etc.
So go the lists in the manual and choose the one that best suits your local environment and driving conditions.
