Engine Emission Control

Continued driving without refilling results in the following actions as required by the CaliforniaAir Resources Board (CARB) and the U.S. Environmental Protection Agency (EPA): • Within a preset distance to empty, speed is limited upon vehicle restart. Prior to this occurring a message appears in the information display. • Further vehicle operation without refilling the diesel exhaust fluid tank causes the engine to enter an idle-only condition. This only occurs upon vehicle refueling or at an extended idle. A message indicates the required actions to resume normal operation. It is required to add a minimum of 1.0 gal (3.8 L) of diesel exhaust fluid to the tank to exit the idle-only condition, but your vehicle is still in the speed-limiting mode until you refill the tank completely. Note: For either vehicle speed limiting or idle-only condition, normal vehicle operation resumes when you refill the diesel exhaust fluid tank. Note: When filling the diesel exhaust fluid tank fromempty, theremay be a short delay before detecting the increased level of fluid. The increased level detection must occur before your vehicle returns to full power. Diesel Exhaust Fluid Guidelines and Information • Use only diesel exhaust fluid that carries the American Petroleum Institute (API) certified diesel exhaust fluid trademark or ISO 22241. • Do not put diesel exhaust fluid in the diesel fuel tank. • Do not overfill the diesel exhaust fluid tank. • Diesel exhaust fluid is corrosive. • Do not re-use the diesel exhaust fluid container once it is emptied.

• Avoid spilling diesel exhaust fluid on painted surfaces, carpeting or plastic components. Immediately wipe away any diesel exhaust fluid that has spilled with a damp cloth and water. If it has already crystallized, use warm water and a sponge. • Store diesel exhaust fluid out of direct sunlight and in temperatures between 23°F (-5°C) and 68°F (20°C). • Diesel exhaust fluid freezes below 12°F (-11°C). • Do not store the diesel exhaust fluid bottle in your vehicle. If it leaks it could cause damage to interior components or release an ammonia odor inside your vehicle. • Diesel exhaust fluid is non-flammable, non-toxic, colorless and water-soluble liquid. • The system has a diesel exhaust fluid quality sensor. Dilution of diesel exhaust fluid or use of any other liquid in the SCR system leads to a diesel exhaust fluid system fault, eventually leading to the vehicle only operating in idle-only mode. • Do not dilute diesel exhaust fluid with water or any other liquid. • An ammonia odor may be smelled when the cap is removed or during refill. Refill diesel exhaust fluid in awell ventilated area.
