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.
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 800km (500 miles) /1 litre. However, consumption can vary greatly depending on your driving style, the weather and the condition of the road.
FREQUENTLY ASKED QUESTIONS
GENERAL - GENERAL
How often should I refill DEF?
The consumption of DEF can vary greatly. An average consumption rate can be 800 km (500 miles) / 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.

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
SAFETY - SAFETY
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?
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.
