Chevrolet Equinox Owners Manual: Diesel Exhaust Fluid

Warning Diesel Exhaust Fluid (DEF) is corrosive. Do not allow it to come in contact with your skin, eyes, or the finished surfaces of the vehicle. If exposed, it may cause skin and eye irritation. Wear skin and eye protection when handling. Inhalation may cause irritation to the upper respiratory tract. Store in a cool, well-ventilated area. For more safety and storage information, see the label of the Diesel Exhaust Fluid container.

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 shut off.

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 for phone numbers to assist in contacting a GM dealer. See Recommended Fluids and Lubricants.

Filling the DEF Tank

Caution Use only DEF 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 affected surface with a damp cloth.

For information on the DEF tank, see Filling the Tank (Gasoline) or Filling the Tank (Diesel).

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 in the DIC. See "Diesel Exhaust Fluid Level (DEF) (Diesel Engine Only)" in Driver Information Center (DIC).

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 the DIC message clearing, the vehicle speed will still be limited.

If the DIC message clears while driving, the speed limitation will be removed gradually.

If DEF is added under freezing conditions, additional time may be required to remove speed limitations and it may require less fluid to fill the DEF tank.

The following actions describe strategies required by the U.S.

Environmental Protection Agency (EPA) and the California Air Resource Board (CARB). The DEF messages relate to these strategies.

The DIC message EXHAUST FLUID RANGE: XXXX km (mi) displays at approximately 1 600 km (1,000 mi) of fluid range remaining.

This message appears again at approximately 500 km (300 mi) of remaining range before the exhaust fluid tank becomes empty.

Below 500 km (300 mi) of range remaining, these messages will appear every time the vehicle is started.

Below 121 km (75 mi) of range remaining, the DIC message EXHAUST FLUID LOW SPEED LIMITED SOON displays. This message will display every time the vehicle is started.

If these warnings are ignored and the DEF tank becomes empty, the DIC message EXHAUST FLUID EMPTY REFILL NOW - 563 KM (350 MI) UNTIL 105 KM/H (65 MPH) MAX SPEED displays. The displayed mileage will decrease as driving continues. A warning light also comes on.
