Nissan ARIYA 2024 Owners Manual
11.1.5. Underbody
Never use high-pressure washers capable of spraying water under the vehicle when the vehicle undercover has been removed. Doing so can damage the Li-ion battery and cause an electrical shock that may result in serious injury or death.
In areas where road salt is used in winter, the underbody must be cleaned regularly. This will prevent dirt and salt from building up and causing the acceleration of corrosion on the underbody and suspension. Before the winter period and again in the spring, the underseal must be checked and, if necessary, re-treated.
