DIESEL EXHAUST FLUID (DEF)

EURO 6, DIESEL ENGINES AND SELECTIVE CATALYTIC REDUCTION:
WHAT IS DEF, HOW TO REFILL AND FAQs

We explain what Euro 6 emissions legislation means for our cars, our drivers and the environment.

WHAT IS DIESEL EXHAUST FLUID (DEF)?

DEF, also known as AdBlue®, AUS 32 and ARLA 32, is a non-toxic, colourless, odourless and non-flammable fluid. Stored in a dedicated tank in your car, DEF is injected into the exhaust system to clean exhaust gases. It breaks down nitrogen oxide (NOx) emissions into harmless water vapour and nitrogen gas.

HOW WILL I KNOW IF MY DEF LEVELS ARE LOW?

The message centre displays a series of messages when the DEF level becomes low.

1. The first message states that the DEF level is at a level where a top up is advised.

2. The second message is accompanied by an AMBER warning icon and states to refill the DEF tank.

3. The third message starts a countdown of the distance remaining until the DEF tank is empty, after which the vehicle will fail to start.

4. The final message is accompanied by a RED warning icon and is displayed when the distance remaining is zero and states that no further restarts will be possible until DEF is added to the tank.

/

NOTE: When the DEF level becomes low, a notification message displays in the message centre. Refill the DEF tank at the earliest opportunity. A Jaguar Retailer/Authorised Repairer can be contacted to arrange a full DEF refill. If required, DEF can be topped up using non-drip refill bottles available from a Jaguar Retailer/Authorised Repairer. An average consumption of DEF is 500 miles (800km) /1 litre. However, consumption can vary greatly depending on your driving style, the weather and the condition of the road.

MAINTAINING DEF

It is important that your Jaguar’s supply of DEF is maintained, as EU legislation means that you cannot start the engine without it. Your car’s message centre will give you advance warning when your DEF level is low and will alert you in plenty of time to book a refill. For mid-service Top-Ups, we are now offering an AdBlue™ refill for £29.99 RRP to manufacturers recommended fill-level, regardless of the amount required*. If you have purchased a Jaguar Service Plan you can get a free refill from your local Retailer.
Please see terms below.

  • How often should I refill DEF?
    The consumption of DEF can vary greatly. An average consumption rate can be 500 miles (800km) / 1 Litre, but this consumption rate can be more than doubled, depending on the driving style, road and weather conditions.
  • How should I store DEF?
    Always store DEF in its original container, and please observe the manufacturer’s storage and handling recommendations shown on the bottle. DEF should never be stored in the vehicle.
  • What happens if I run out of DEF?
    Should you run out of DEF, your Jaguar will not re-start after you switch off the engine - this is a requirement of EU6 emissions legislation. The tank will need to be refilled with a minimum of 3.6 litres of DEF before the vehicle will start.

  • How do I check my DEF level?
    The distance until your next DEF refill can be viewed at any time in the message centre on the dashboard*.

    Follow these simple steps:

    1. Switch on the ignition, but do not start the engine
    (Check that a valid smart key is inside the vehicle and ensure that the brake pedal is not pressed. Hold down the engine START/STOP button until the instrument panel warning lamps illuminate)

    2. Press the OK button on the steering wheel control to access the Main Menu
    (On some models, repeatedly press the OK button until Driver Assistance is displayed)

    3. Using the down arrow button on the steering wheel control, scroll down and highlight Vehicle Info

    4. Press the OK button to confirm selection

    5. Scroll down to highlight Diesel Exhaust Fluid
    (On some models this is displayed as Next Service)

    6. Press the OK button to confirm selection. The Diesel Exhaust Fluid range is then displayed.

    * Not all vehicles are equipped to display the above information. Contact your Retailer/Authorised Repairer for clarification.
  • Can I refill the DEF tank myself?
    Yes, you can purchase 1.89 litre non-drip bottles of DEF from your local Jaguar Retailer/Authorised Repairer to refill the tank yourself. These bottles have been specifically designed for ease of use and to prevent any dripping. We do not recommend refilling the tank using any other type of container.

    Do not pour any other liquids into the DEF tank or DEF that does not meet the standard ISO22241-1 or DIN 70070 as this will compromise the correct operation of your vehicle.

    If you pour DEF into your fuel tank by mistake, DO NOT start the engine, and call your local Jaguar Retailer/Roadside Assistance immediately.

    Commercial vehicle DEF pumps at fuel stations must never be used because the flow rate is too high and this will damage the vehicle’s DEF tank.

    Refer to your Owner’s Handbook for instructions on how to refill your DEF tank

  • Is DEF hazardous?
    Although DEF is non-hazardous, should it come in to contact with any part of your body, or it is ingested by accident, please refer to the advice on the packaging and seek medical advice. If DEF comes into contact with your Jaguar’s paintwork, simply wipe it off, and rinse the area with soapy water. However, DEF can stain upholstery and clothing – if spilt, DEF should be removed immediately using cold water and a damp cloth.

WHAT IS EURO 6?

Euro 6 is a piece of European Legislation aimed at making cars more environmentally friendly by limiting their exhaust emissions. The legislation sets restrictions on how much nitrogen oxide (NOx) and hydrocarbon gases may be emitted per kilometre by a road vehicle.

Petrol and diesel cars are subject to different restrictions under the new Euro 6 legislation. For diesel cars, the permitted level of NOx emissions has been brought down to 80 mg/km (from 180 mg/km), while the permitted level of hydrocarbons emissions has been brought down to 170 mg/km (from 230 mg/km). The permitted level of NOx emissions for petrol cars remains at 60 mg/km, while the permitted level of hydrocarbons emissions remains at 100 mg/km.

Along with other car manufacturers, Jaguar is legally obligated to comply with these new regulations by the following dates:

 - From 1st January 2015, all newly introduced vehicles must meet Euro 6 standards. This includes any new models on the market, for example: Jaguar XE
 - Vehicles already on sale must comply with Euro 6 by 1st September 2015, but;
 - Individual vehicles already on sale that were built by, and dispatched from, the manufacturer before 1st June 2015 can continue to be sold until 1st September 2016. However, the manufacturer must apply for derogation in these instances.

WHAT IS SELECTIVE CATALYTIC REDUCTION (SCR) TECHNOLOGY?

Selective Catalytic Reduction (SCR) technology is fitted to all Jaguar diesel vehicles from 2016 Model Year. It enables Jaguar to meet EU6 emissions legislation by reducing the levels of nitrogen oxide (NOx) emitted from the exhaust system by up to 90%. In addition to a new generation of catalytic converter, SCR Technology requires the use of Diesel Exhaust Fluid (DEF).

*AdBlue® usage is dependant on driving style and supplied figures are indicative only

The DEF quality and flow rate are similarly monitored. You will be notified if the system detects inferior DEF quality or a malfunction, starting with an alert that gives you 530 miles to correct the problem. Once more, the vehicle will not restart if you don’t take corrective action in this period.

PETROL AND DIESEL EMISSION STANDARDS IMPROVEMENT 2000 – 2014

Technical innovations have helped to lower vehicle emissions over the last 15 years. Since 2000, NOx limits for diesel engines have reduced by 84% and particulates by 90%.

The table below outlines the reductions:

2000 - Euro 3 2005 - Euro 4 2009 - Euro 5 2014 - Euro 6
