Useful care tips for all Unimog owners.

25 years of service and more are not uncommon for the Unimog. The prerequisite for this: regular maintenance and care. Precisely because it is constantly exposed to environmental influences in its work as an all-rounder, the Unimog should be checked and serviced regularly. But workshop experts don't always have to be involved. Many small maintenance measures can also be carried out by drivers and owners themselves in everyday work - for safe use and value retention.

Especially important in the winter season.

Regular engagement is the alpha and omega of vehicle care. Although this motto applies all year round, the Unimog, like all vehicles, needs special attention in the winter months. Then the increased contact with salts, ice and dirt requires special attention and careful cleaning. Damage to the paintwork and preservation should be detected as early as possible and repaired by an authorised specialist workshop.

Unimog Service & Parts has created a practical overview with useful care tips for all Unimog owners. These are simple to-dos that you can do yourself at regular intervals with little effort.

Details on the listed measures can be found in the operating instructions for the vehicle. In this there are application-related deviations that should be observed.
