Fuel and Refueling WARNINGS The normal operating temperature of the exhaust system is very high. Never work around or attempt to repair any part of the exhaust system until it has cooled. Use special care when working around the diesel oxidation catalytic converter and/or the diesel particulate filter (DPF). The diesel oxidation catalytic converter and/or the DPF heats up to a high temperature after only a short period of engine operation and can stay hot even after the engine is turned off. Failure to follow these instructions may result in personal injury. Note: Additions of aftermarket devices or modifications to the exhaust system can reduce the effectiveness of the exhaust system as well as cause damage to the exhaust system or engine. These actions may also affect your vehicle's warranty. See the Warranty Guide for more information. The diesel resonator tail-pipe assembly is a uniquely functioning device that accompanies the diesel particulate filter assembly. The tail-pipe assembly serves multiple functions. First, it serves as an acoustic device to attenuate exhaust noise. Second, it provides an exit path for the exhaust from your vehicle. It also helps control the temperature of the exhaust during diesel particulate filter regeneration events. The visible holes in each leg of the twin tip and the holes under the shield just inboard of the right rear tire(s) are functional. You need to keep the holes clear of mud, debris or foreign material to maintain proper function of the exhaust system. Clean and remove debris or foreign material if present as needed. Spraying with a hose during regular washing of your vehicle should help keep holes clean and clear of debris or foreign material. Emission Control System Laws WARNING Do not remove or alter the original equipment floor covering or insulation between it and the metal floor of the vehicle. The floor covering and insulation protect occupants of the vehicle from the engine and exhaust system heat and noise. On vehicles with no original equipment floor covering insulation, do not carry passengers in a manner that permits prolonged skin contact with the metal floor. Provide adequate insulation. Failure to follow these instructions may result in fire or personal injury. In the U.S. federal law and certain state laws prohibit removing or rendering inoperative emission control system(s). Similar federal or provincial laws may apply in Canada. Ford recommends against any vehicle modification without determining applicable law. Tampering with emissions control systems (including related sensors and the Diesel Exhaust Fluid (DEF) injection system) can result in reduced engine power and the illumination of the service engine soon light. 130 Transit (TTH) Canada/United States of America, enUSA, Edition date: 03/2014, Third Printing
