Fuel and Refueling 5. When the DEF tank is full, the fluid level in the bottle will stop dropping, indicating the fluid has stopped flowing. Diesel Exhaust Fluid (DEF) filling station nozzle fill Filling the Diesel Exhaust Fluid (DEF) tank using a nozzle is similar to a normal fuel fill. The nozzle will shut off automatically when the tank is full. Do not continue to fill the tank as this may cause spilling and overfill can cause damage to the tank. Note: Some filling station nozzles may prevent filling of your DEF tank due to a magnetic mechanism in the nozzle. This is not a problem with your vehicle. To refill your tank either locate another filling station or use a bottle to refill the tank. E163359 6. Once the level in the DEF bottle has stopped dropping, return the container to the vertical position slightly below the DEF filler port and let any DEF drain out of the spout. DO NOT try to continue to add DEF to the tank by shaking or repositioning the container to induce flow. This may cause spilling and overfill the tank. Overfilling the DEF tank can cause damage to the tank. 7. Once the spout has drained, remove the spout from the DEF filler port and install the blue cap on the DEF filler port. 8. Remove the spout from the diesel exhaust fluid container and install the cap back on the bottle. 9. If the container is empty, discard the empty container, or recycle if possible. If there is DEF left in the container, retain it for later use. The spout is re-useable; after use, rinse it with clean water and store the spout to keep it clean. Do not use the DEF spout with any other chemicals. 10. Wipe away any DEF that has spilled on painted surfaces with water and a damp cloth. Filling the Diesel Exhaust Fluid (DEF) tank in cold climates Diesel Exhaust Fluid (DEF) will freeze below 12°F (-11°C); however, your vehicle is equipped with an automatic preheating system which allows the DEF system to operate below 12°F (-11°C). When your vehicle is not in operation for an extended period with temperatures at or below 12°F (-11°C), the DEF tank could freeze. If the tank is OVERFILLED and freezes, it could be damaged, therefore DO NOT OVERFILL. To prevent overfilling of the DEF tank when filling with a bottle, Ford recommends using Motorcraft® Diesel Exhaust Fluid (DEF). Additionally, if the information display indicates EXHAUST FLUID UNDER 1/2 FULL, you should only add a MAXIMUM of 2 gallons (6.7L) of DEF to the tank to prevent freeze damage due to overfilling. If the information display indicates EXHAUST FLUID LEVEL OK, do not add DEF. 26 Super Duty (TFA) , enUSA
