Nissan X-Trail e-POWER 2023 Owners Manual
10.1.5. Underbody
In areas where road salt is used in the winter, it is necessary to clean the vehicle's underbody regularly in order to prevent dirt and salt from building up and causing the acceleration of corrosion on the underbody and suspension.
Before the winter and again in the spring, the underseal must be checked and, if necessary, re-treated.
