Page 3: Selective Catalytic Reduction (Scr)
selective catalytic reDuction (scr) The SCR system is an after-treatment system, since it treats the vehicle’s exhaust after combustion. Here’s how it works: A fine mist of DEF is injected into the exhaust while the engine is running. The heat from the exhaust converts the DEF into ammonia. When the ammonia, mixed with exhaust gases, reaches the SCR catalyst, the NOx emissions are broken down. -
Page 4: Diesel Exhaust Fluid (Def)
using diesel exhaust fluid Diesel exhaust fluiD (Def) Diesel Exhaust Fluid (DEF) is a non-flammable fluid comprised of 33% ammonia-based urea and 67% purified water. DEF is used with diesel engine exhaust systems to reduce the amount of emissions produced by turning Nitrogen Oxide (NOx) into nitrogen and water vapor. - Page 5 refilling your Def tank DEF is stored in a 5.3-gallon tank located under the passenger side of the cab.

An electronic onboard warning system provides you with numerous warnings in the Driver Information Center (DIC) to help you maintain adequate DEF levels, alert you if the DEF quality is poor or if there are concerns with the system. - Page 7 maintaining Def Quality The quality of DEF in the tank must be maintained for the vehicle to run correctly. Care should be taken to prevent any contaminants from getting into the fluid. Only GM-approved DEF, or DEF fluid containing the API certified or ISO 22241 label, should be used.

Page 8: Frequently Asked Questions (Faqs)
frequently asked questions (faqs) Q. what is the warranty coverage for the scr system? a. The SCR system is covered under the emissions limited warranty just like any other emissions component. However, system damage caused by using incorrect fluid is not eligible for warranty reimbursement. See dealer for details. - Page 9 Q. Do trucks equipped with scr have a Diesel particulate filter (Dpf)? a. Yes they do. The DPF serves a different function than the SCR; it helps remove soot from the exhaust. For 2011, the range between Duramax DPF regeneration cycles has been lengthened by 75% and is now up to 700-miles.
- Page 10 frequently asked questions (faqs) Q. will Def containers have a date stamp? a. Yes, each container should be dated. Q. how do you monitor a truck’s Def level? a. Very easily. A DIC message will alert the driver whenever a vehicle’s DEF level begins to run low (see DEF levels explanation earlier in this brochure).
- Page 11 Q. is there a way to bypass a system-imposed, low-speed restriction? a. No. Government regulations mandate the system be tamper proof. Q. will chassis cab upfitters be affected by the location of the Def tank? a. Since the tank is located under the cab, it does not impact the installation of any bodies.
