2006 Infiniti FX35 Owner's Manual - Page 300

CAUTION NEVER remove dirt, sand or other debris from the passenger compartment by washing it out with a hose. Remove dirt with a vacuum cleaner or broom. Never allow water or other liquids to come in contact with electronic components inside the vehicle as this may damage them. 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 an INFINITI dealer. 7-6 Appearance and care
