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 reser ve 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.
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.
Please contact your authorized Toyota dealer or repairer, or another duly qualified and equipped professional to confirm your "Euro" emissions standard.

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 ser vices, 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 reser ved 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).

Recommendations on storage
Never store bottles of AdBlue® in your vehicle.
AdBlue® freezes at about -11°C and deteriorates above 25°C. It is recommended that bottles be stored in a cool area and protected from direct sunlight.Under these conditions, the fluid can be kept for at least a year.If the additive has frozen, it can be used once it has completely thawed out.
Procedure
Before starting the top-up procedure, ensure that the vehicle is parked on a flat and level sur face.
F Switch off the ignition and remove the key, or if your vehicle has one, press the START/STOP button to switch off the engine.
F For access to the AdBlue® tank, open the left-hand front door.F From below, pull the black cover.
F Turn the blue cap a 6th of a turn anti-clockwise.F Lift off the cap.
Do not dispose of AdBlue® bottles in the household waste. Place them in a container provided for this purpose or take them to your dealer.
In wintry conditions, ensure that the temperature of the vehicle is above -11°C. Other wise the AdBlue® may be frozen and so cannot be poured into its tank. Park your vehicle in a warmer area for a few hours to allow the top-up to be carried out.

F After emptying the bottle, wipe away any spillage around the tank filler using a damp cloth.
If any additive is split or splashed, wash immediately with cold water or wipe with a damp cloth.If the additive has crystallised, clean it off using a sponge and hot water.
F Refit the blue cap to the tank and turn it a 6th of a turn clockwise, to its stop.
Important: when topping-up after running out of additive, signalled by the message "Top up emissions additive: Starting prevented", you must wait for about 5 minutes before switching on the ignition, without opening the driver's door, unlocking the vehicle, introducing the key into the ignition switch, or placing the key of the "Smar t Entr y & Star t System" inside the vehicle.Switch on the ignition, then wait for 10 seconds before starting the engine.
F Obtain a bottle of AdBlue®. After first checking the use-by date, read carefully the instructions on use on the label before pouring the contents of the bottle into your
vehicle's AdBlue® tank.
Freezing of the AdBlue®
AdBlue® freezes at temperatures below around -11°C.The SCR system includes a heater for the AdBlue® tank, allowing you to continue driving in very cold conditions.F Refit the black cover, starting at the top.F Close the door.
