Yes you need to tension belt a wee bit more. There is more load on alternator when you start engine in the morning. Glowplugs and thermoplungers stay on for a wee while causing auxiliary drive belt to screech like a stuck pig. Some Kangoos have an automatic spring loaded tensioner for aux drive belts and some need to be manually tensioned and tension checked using a special instrument.
There is more info in below thread:

Don't keep on driving without sorting this out. You'll quickly wear out your belt and worst case scenario is timing belt failure.
