It supposed to be changed at 80k km or before 100k km. If you touched that km, get that change.

If in doubt check with dealer if they have record, if no record found and its more than 100k kms better get it change than not. As timing belt failure becomes very expensive and in some cases you need to buy new engine. So these couple of thousand is better than that much money and hassle.
