Maintenance and Specifications 5. 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. 6. Once the spout has drained, remove the spout from the DEF filler port and install the blue cap on the DEF filler port. 7. Remove the spout from the DEF container and install the cap back on the bottle. 8. If the container is empty, discard the empty container and spout, or recycle if possible. If there is some DEF left in the container, retain it and the spout for later use. Store the spout to ensure it is kept clean. 9. Wipe away any DEF that has spilled on painted surfaces with water and a damp cloth. • DEF filling station nozzle fill: Filling the 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 the tank which can cause damage. 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. Filling the DEF tank in cold climates 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 the vehicle is not in operation for an extended period of time 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. 34 2011 Diesel (eco) Supplement, 5th Printing USA (fus)
