Q: CAN I REFILL THE DEF TANK MYSELF?
Yes, you can purchase 4-pint non-drip bottles of DEF from your local Jaguar Retailer 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
