416 TECHNICAL SPECIFICATIONSFuel System Cautions NOTE:Intentional tampering with the emissionscontrol system can result in civil penalties beingassessed against you.Carbon Monoxide WarningsFUEL REQUIREMENTS – DIESEL ENGINEFederal law requires that you must fuel thisvehicle with Ultra Low Sulfur Highway Dieselfuel (15 ppm Sulfur maximum) and prohibitsthe use of Low Sulfur Highway Diesel fuel(500 ppm Sulfur maximum) to avoid damage tothe emissions control system.Use good quality diesel fuel from a reputablesupplier in your vehicle. For most year-roundservice, No. 2 diesel fuel meeting ASTM(formerly known as the American Society forTesting and Materials) specification D-975Grade S15 will provide good performance. If thevehicle is exposed to extreme cold (below 20°For -7°C), or is required to operate atcolder-than-normal conditions for prolongedperiods, use climatized No. 2 diesel fuel ordilute the No. 2 diesel fuel with 50% No. 1 dieselfuel. This will provide better protection from fuelgelling or wax-plugging of the fuel filters.CAUTION!Follow these guidelines to maintain your vehi-cle’s performance: The use of leaded gasoline is prohibited byFederal law. Using leaded gasoline canimpair engine performance and damagethe emissions control system. An out-of-tune engine or certain fuel or igni-tion malfunctions can cause the catalyticconverter to overheat. If you notice apungent burning odor or some light smoke,your engine may be out of tune or malfunc-tioning and may require immediate service.Contact an authorized dealer for serviceassistance. The use of fuel additives, which are nowbeing sold as octane enhancers, is notrecommended. Most of these productscontain high concentrations of methanol.Fuel system damage or vehicle perfor-mance problems resulting from the use ofsuch fuels or additives is not the responsi-bility of the manufacturer and may void ornot be covered under the New VehicleLimited Warranty.WARNING!Carbon monoxide (CO) in exhaust gases isdeadly. Follow the precautions below to pre-vent carbon monoxide poisoning: Do not inhale exhaust gases. They containcarbon monoxide, a colorless and odorlessgas, which can kill. Never run the engine ina closed area, such as a garage, and neversit in a parked vehicle with the enginerunning for an extended period. If thevehicle is stopped in an open area with theengine running for more than a shortperiod, adjust the ventilation system toforce fresh, outside air into the vehicle. Guard against carbon monoxide withproper maintenance. Have the exhaustsystem inspected every time the vehicle israised. Have any abnormal conditionsrepaired promptly. Until repaired, drive withall side windows fully open.WARNING!Do not use alcohol or gasoline as a fuelblending agent. They can be unstable undercertain conditions and hazardous or explo-sive when mixed with diesel fuel.
