9-28 Driving and Operating Filling the DEF Tank Exhaust Fluid Low A full DEF tank will last for several thousand kilometers (miles), depending on vehicle usage. As the exhaust fluid level drops, warnings will automatically be displayed in the DIC. Exhaust fluid level status is available on the DIC under the vehicle Information button. See "Diesel Exhaust Fluid Level (Diesel Engine Only)" in Driver Information Center (DIC) on page 5-23. To avoid vehicle speed limitations, the DEF tank should be refilled at the first opportunity after a low warning indication. If DEF is added before the EXHAUST FLUID EMPTY REFILL NOW message appears, it may take several km/mi for the DIC message to update. If the vehicle speed has been limited and DEF has been added, it may take up to 30 seconds after engine start with the vehicle stopped for the EXHAUST FLUID EMPTY REFILL NOW message to clear. If the vehicle is driven prior to DEF is used with diesel engines to reduce the amount of regulated emissions produced. The fluid level in the DEF tank must be maintained for the vehicle to run correctly. The capacity of the DEF tank is 18.5 L (4.9 gal). It is normal to hear the DEF system purge fluid back into the tank after the vehicle is shutoff. Locating Diesel Exhaust Fluid DEF can be purchased at a Chevrolet dealer. It can also be purchased at authorized vehicle dealerships. Additionally, some diesel fueling stations or retailers may have DEF for purchase. For vehicles with an active OnStar subscription, OnStar can help to locate a DEF retailer. See Customer Assistance Offices on page 13-3 for phone numbers to assist in contacting a GM dealer. See Recommended Fluids and Lubricants on page 11-12. { Caution Use only exhaust fluid that is GM approved, or fluid containing the API certified or ISO 22241 label. The use of other fluids could damage the system, requiring costly repairs that will not be covered by the vehicle warranty. When adding DEF to an empty or very low tank, always add at least 7.6 L (2 gal) of fluid to release the vehicle from speed limitation. To prevent damage to the system, do not overfill the DEF tank. When fluid reaches the top of the fill pipe, stop filling. Do not top off the DEF tank. If you spill DEF during filling, wipe any effected surface with a damp cloth. For information on the DEF tank, see Filling the Tank on page 9-61.
