AdBlue® and SCR system
for Diesel engines
To assure respect for the environment and conformity with the new Euro 6 emissions standard, without adversely affecting the per formance or fuel consumption of Diesel engines, Toyota has taken the decision to equip its vehicles with an effective system that associates SCR (Selective Catalytic Reduction) with a particle filter (DPF) for the treatment of exhaust gases.
Presentation of the SCR system
Using a fluid called AdBlue® containing urea, a catalytic converter turns up to 85% of nitrogen
oxides (NOx) into nitrogen and water, which are harmless to health and the environment.
The AdBlue® is held in a special tank with a capacity of about 22 litres: this provides a driving range of about 12 500 miles (20 000 km), after which an alert is triggered warning you when the reserve remaining is enough for just 1 500 miles (2 400 km).
During each scheduled service of your vehicle by an authorized Toyota dealer or repairer, or another duly qualified and equipped professional, the AdBlue® tank is refilled in order to allow normal operation of the SCR system.
Once the AdBlue® tank is empty, a system required by regulations prevents starting of the engine.If the SCR is faulty, the level of emissions from your vehicle will no longer meet the Euro 6 standard: your vehicle becomes polluting.In the event of a confirmed fault with the SCR system, you must go to an authorized Toyota dealer or repairer, or another duly qualified and equipped professional as soon as possible: after a running distance of 650 miles (1 100 km), a system will be triggered automatically to prevent engine starting.When filling the tank, the filling rate must not exceed 40 litres per minute.
If the estimated mileage between two services is greater than 12 500 miles (20 000 km), we recommend that you go to an authorized Toyota dealer or repairer, or another duly qualified and equipped professional to have the necessary top-up carried out.
