Your vehicle has a selective catalytic reductant system to help reduce exhaust emission levels by injecting diesel exhaust fluid into the exhaust system.The engine may not start if you tamper with or disable the selective catalytic reductant system.
For the system to correctly operate, you must maintain the fluid level. The minimum fluid refill quantity required to restart the engine is 1.51 gal (5.7 L).
Note:   If your vehicle is on a gradient, the minimum fluid refill quantity required to restart the engine may be greater than 1.51 gal (5.7 L).
Diesel Exhaust Fluid Guidelines
  • Do not put in the vehicle fuel tank. This can cause engine damage not covered by the vehicle Warranty.
  • Do not overfill the tank.
  • Do not dilute with water or any other liquid.
  • Do not re-use an empty fluid container.
  • Do not store in direct sunlight.
  • Store at temperatures between 23 °F (-5 °C) and 68 °F (20 °C).
  • Do not store fluid containers in your vehicle.
  • The fluid is non-flammable, non-toxic, colorless and water-soluble.
Filling the Diesel Exhaust Fluid Tank
Diesel Exhaust Fluid Filler Cap
The diesel exhaust fluid tank filler pipe is next to the fuel tank filler pipe and has a blue cap. Fill the tank using a fluid pump at a diesel exhaust fluid filling station or a diesel exhaust fluid container.
American Petroleum Institute Certification for Diesel Exhaust Fluid
 Only use diesel exhaust fluid that is certified by the American Petroleum Institute (API). Non-certified diesel exhaust fluid use can cause damage not covered by the vehicle Warranty.
Note:   Wash off any fluid that may have spilled on to a painted surface with soapy water.
Filling in Cold Climates
Diesel exhaust fluid may freeze when the temperature is below 12 °F (-11 °C). Your vehicle has a preheating system which allows the fluid to operate below 12 °F (-11 °C).If you overfill the diesel exhaust fluid tank and the fluid freezes, it may cause damage not covered by the vehicle Warranty.
Filling the Diesel Exhaust Fluid Tank Using a Fuel Station Pump
WARNING   WARNING:  Keep diesel exhaust fluid out of reach of children. Avoid contact with skin, eyes or clothing. In case of contact with your eyes, flush immediately with water and get prompt medical attention. In case of contact with your skin, clean immediately with soap and water. If you swallow any diesel exhaust fluid, drink plenty of water, call a physician immediately.
WARNING   WARNING:  Only refill the diesel exhaust fluid tank in a well ventilated area. When you remove the diesel exhaust fluid tank filler cap or a diesel exhaust fluid container cap, ammonia vapors may escape. Ammonia vapors can be irritating to skin, eyes and mucous membranes. Inhaling ammonia vapors can cause burning to the eyes, throat and nose and cause coughing and watery eyes.

Filling the diesel exhaust fluid tank using a fuel station pump is similar to refueling your vehicle.
  1. Fully open the fuel filler door.
Fuel Flap Closed
  1. Remove the diesel exhaust fluid tank filler cap.
  1. Fully insert the diesel exhaust fluid pump nozzle.
AdBlue Filler Tube Filling Angle
  1. Operate the pump nozzle within the area shown.
Note:   The pump nozzle shuts off when the tank is full.
  1. Slightly raise the diesel exhaust fluid pump nozzle and then slowly remove it.
  1. Replace the diesel exhaust fluid tank filler cap.Turn it clockwise until you feel a strong resistance.
Do not attempt to start the engine if you have filled the diesel exhaust fluid tank with incorrect fluid. Incorrect diesel exhaust fluid use could cause damage not covered by the vehicle Warranty. Have your vehicle immediately checked.
Filling the Diesel Exhaust Fluid Tank Using a Container
WARNING   WARNING:  Keep diesel exhaust fluid out of reach of children. Avoid contact with skin, eyes or clothing. In case of contact with your eyes, flush immediately with water and get prompt medical attention. In case of contact with your skin, clean immediately with soap and water. If you swallow any diesel exhaust fluid, drink plenty of water, call a physician immediately.
WARNING   WARNING:  Only refill the diesel exhaust fluid tank in a well ventilated area. When you remove the diesel exhaust fluid tank filler cap or a diesel exhaust fluid container cap, ammonia vapors may escape. Ammonia vapors can be irritating to skin, eyes and mucous membranes. Inhaling ammonia vapors can cause burning to the eyes, throat and nose and cause coughing and watery eyes.

Always follow the manufacturer's instructions.
  1. Remove the fluid container cap.
  1. Place the spout on to the container and tighten it until you feel a strong resistance.
Fuel Flap Closed
  1. Remove the diesel exhaust fluid tank filler cap.
  1. Insert the spout into the diesel exhaust fluid tank filler pipe until the seal on the spout fully seats.
  1. Pour the fluid into the tank.
Note:   The fluid stops flowing when the tank is full.
  1. Return the container to the vertical position slightly below the diesel exhaust fluid tank filler pipe.
  1. Allow any fluid remaining in the spout to drain back into the container.
  1. Remove the spout from the diesel exhaust fluid tank filler pipe.
  1. Remove the spout from the diesel exhaust fluid container and replace the cap.
  1. Replace the diesel exhaust fluid tank filler cap.Turn it clockwise until you feel a strong resistance.
Do not attempt to start the engine if you have filled the diesel exhaust fluid tank with incorrect fluid. Incorrect diesel exhaust fluid use could cause damage not covered by the vehicle Warranty. Have your vehicle immediately checked.
Selective Catalytic Reductant System Warning Lamp
Diesel Exhaust Fluid Level Low  The warning lamp illuminates if the system detects the diesel exhaust fluid level is low or if there is a system malfunction.
If the warning lamp illuminates, the information display messages give you an indication whether the concern is fluid related or if there is a selective catalytic reductant system malfunction.If the warning lamp illuminates when your vehicle is moving, and the fluid is at a sufficient level, this indicates a system malfunction. Have your vehicle checked as soon as possible.
Note:   When filling the diesel exhaust fluid tank from empty, there may be a short period before the increased diesel exhaust fluid level is registered.
