AdBlue™ is used to reduce the amount of nitrogen oxides in exhaust
gas. Make sure to observe the following precautions regarding
AdBlue™.
O AdBlue™ is consumed in the process of driving.
O When AdBlue™ is depleted, the engine cannot be restarted.
O When AdBlue™ needs to be refilled, have it refilled at any autho-
rized Toyota retailer or Toyota authorized repairer, or any reliable
repairer.
It may be a criminal offence to use a vehicle that does not consume
any reagent if it is required for the reduction of emissions.
QPossible driving range
The amount of AdBlue™ that is consumed while driving differs
according to the driving conditions and driving environment. When
the amount of AdBlue™ that is consumed increases, the possible
driving range until it is necessary to refill AdBlue™ decreases.
*1: When the vehicle is used at high elevations and in low temperatures, the
amount of AdBlue™ that is consumed increases.
*2: During normal driving, 1.0 L (1.1 qt., 0.9 Imp.qt.) of AdBlue™ is con-
sumed approximately every 600 km (373 miles). Also, after a full refill, the
vehicle can be driven for approximately 10000 km (6214 miles) before all
AdBlue™ is depleted.
