CAUTION
Chemicals used for road surface de-icing are extremely corrosive. They accelerate corrosion and deterioration of underbody components such as the exhaust system, fuel and brake lines, brake cables, floor pan and fenders.
In winter, the underbody must be cleaned periodically.
For additional protection against rust and corrosion, which may be required in some areas, consult a NISSAN dealer.
