What is AdBlue™?

Diesel engines are required to meet tough NOx standards which help control air pollution. The preferred method involves injecting a high purity fluid called Diesel Exhaust Fluid or AdBlue™ into the exhaust system.

When your vehicle uses AdBlue, the Nitrogen Oxide produced by your engine is converted into nitrogen and steam. This helps to reduce the harmful Nitrogen Oxide emissions, which is a major source of atmospheric pollution. For this reason, AdBlue plays a crucial role in reducing the environmental impact of your vehicle.

AdBlue is a harmless substance and is very easy to use. It is not a fuel or a fuel additive – it is a simple but effective high purity urea solution. AdBlue must be used in a dedicated tank in your vehicle, and refilled when required. It is essential that you refill prior to depletion, as your vehicle will not run without it.

How do I refill ADBLUE ™?

You can refill your AdBlue yourself, although we recommend that you ask one of our mechanics as they have received specialised training. Here is a step by step guide for refilling your AdBlue:

1.Ensure the vehicle is parked on a level surface, turn the engine switch off, then open the hood.
2.Open the AdBlue™ tank cap.

It’s important not to use any urea solution other than AdBlue™.

3.Insert a bottle of AdBlue™ and fully tighten it.
4.Push down on the bottle. AdBlue™ will begin to refill.

Refill AdBlue™ slowly so that it does not spill. Do not remove the bottle until it is empty.

5.Check that no AdBlue™ remains in the bottle, and then remove it. Repeat steps 3-5 until approximately 3.8L (4.0 qt, 3.3 lmp.qt.) or more of AdBlue™ have been refilled.
6.Close the AdBlue™ tank cap. Turn the cap until you hear a click and check that the engine starts – this may take a few seconds longer than normal.

Important things to keep in mind

When using AdBlue™ there are some clear rules that should be followed. The vehicle will not start if the AdBlue™ level is too low.

When refilling AdBlue™

Observe the following precautions. Failure to do so may result in damage to the vehicle parts, paint, etc.

  • Do not use urea solution other than AdBlue™.
  • If AdBlue™ is added at a rate of more than 3 L (3.2 qt., 2.6 Imp. qt.)`per minute the AdBlue™ may overflow from the refill port. Do not use refilling equipment available at gas stations or elsewhere, as the equipment will add more than 3 L (3.2 qt., 2.6 Imp.qt.) of AdBlue™ per minute.
  • If AdBlue™ comes into contact with any painted surfaces on the vehicle, immediately wash the affected areas with water.
  • If AdBlue™ is spilled inside the engine compartment, immediately wipe it with a wet cloth.
When storing AdBlue™

Observe the following precautions. Failure to do so may result in damage to vehicle parts, paint, etc., and changes in the chemical compounds of AdBlue™ may cause unpleasant odors.

  • Do not leave AdBlue™ inside the vehicle.
  • Tightly seal AdBlue™ containers and store them in a cool, dry location with good ventilation and no exposure to direct sunlight.
