What is Diesel Exhaust Fluid (DEF)?
Diesel Exhaust Fluid (DEF) also known as AdBlue™, is a non-toxic, colourless, odourless and non-flammable fluid. Stored in a dedicated tank in your car, it is injected into the exhaust system to clean exhaust gases.
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 will I know if my DEF/ AdBlue™ levels are low?
The message centre displays a series of messages when the DEF level becomes low.
The first message states that the DEF level is at a level where a Top-Up is advised.
The second message is accompanied by an AMBER warning icon and states to refill the DEF tank.
The third message starts a countdown of the distance remaining until the DEF tank is empty, after which the vehicle will fail to start.
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
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 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.
