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: - Euro 5.0: about 22 litres, this provides a driving range of about 10 500 miles (17 000 km); - Euro 6.2: about 20 litres, will cover a driving range of approximately 4 fill ups of fuel, about 3 000 miles (5 000 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 ser vice 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.
Please contact your authorized Toyota dealer or repairer, or another duly qualified and equipped professional to confirm your "Euro" emissions standard.
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 ser vices is greater than 12 500 miles (20 000 km) for Euro 5.0 or more than 4 fill ups of fuel, about 3 000 miles (5 000 km) for Euro 6.2, 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.

Topping-up the AdBlue®
Filling the AdBlue® tank is an operation included in every routine ser vice on your vehicle by an authorized Toyota dealer or repairer, or another duly qualified and equipped professional.Nevertheless, given the capacity of the tank, it may be necessary to top-up the fluid between services, more particularly if an alert (warning lamps and a message) signals the requirement.You can go to an authorized Toyota dealer or repairer, or another duly qualified and equipped professional.If you envisage topping-up yourself, please read the following warnings carefully.
Precautions in use
Keep AdBlue® out of the reach of children, in its original bottle.Never transfer AdBlue® to another container: it would lose its purity.
Use only AdBlue® fluid that meets the ISO 22241 standard.
Never dilute AdBlue® with water.Never pour AdBlue® into the Diesel fuel tank.
The supply in a non-drip bottle simplifies topping-up. You can obtain 1.89 litre (half a US gallon) bottles from an authorized Toyota dealer or repairer, or another duly qualified and equipped professional.
Never top-up from an AdBlue® dispenser reserved for heavy goods vehicles.
AdBlue® is a urea-based solution. This liquid is non-flammable, colourless and odourless (kept in a cool area).In the event of contact with the skin, wash the affected area with soap and water. In the event of contact with the eyes, wash (irrigate) the eyes with large amounts of water or with an eye wash solution for at least 15 minutes. If a burning sensation or irritation persists, get
medical attention.If swallowed, immediately wash out the mouth with clean water and then drink plenty of water.In certain conditions (high ambient temperature, for example), the risk of release of ammonia cannot be excluded: do not inhale the fluid. Ammonia vapour has an irritant effect on mucous membranes (eyes, nose and throat).ImportantIf your vehicle's AdBlue® tank is completely empty (which is confirmed by the alert messages and the impossibility of starting the engine) you must add at least 3.8 litres (so two 1.89 litre bottles).
