Yes. The rubber belt perishes over time, so it usually gets serviced at 6 years or xx mileage, whichever first.Timing service is also kilometres/years, whichever comes first? because it's only 10000kms.
I stretched mine a bit because I personally think that 100k is a better benchmark, but no dealer would be willing to take that risk. My Peugeot is almost 8 years old now and just reached 100k. I'm doing mine next week.
