Emission Control System (SKYACTIV-D 2.2)
This vehicle is equipped with an emission control system (the catalytic converter and the Selective Catalytic Reduction (SCR) system*1 are part of this system) that enables the vehicle to comply with existing exhaust emissions requirements.
-
SCR system is designed to reduce nitrogen oxide (NOx) in the exhaust gas and purify the exhaust gas by injecting it with AdBlue®. For more details, refer to the Selective Catalytic Reduction (SCR) System (Search).
About the catalytic converter
Never park over or near anything flammable:
Parking over or near anything flammable, such as dry grass, is dangerous. Even with the engine turned off, the exhaust system remains very hot after normal use and could ignite anything flammable. A resulting fire could cause serious injury or death.
Ignoring the following precautions could cause lead to accumulate on the catalyst inside the converter or cause the converter to get very hot. Either condition will damage the converter and cause poor performance.
-
Do not drive your Mazda with any sign of engine malfunction.
-
Do not coast with the ignition switched off.
-
Do not descend steep grades in gear with the ignition switched off.
-
Do not operate the engine at high idle for more than 2 minutes.
-
Do not tamper with the emission control system. All inspections and adjustments must be made by a qualified technician.
-
Do not push-start or pull-start this vehicle.
About the SCR system
Be careful not to allow the AdBlue® fluid to run out. If the AdBlue® fluid completely runs out, the SCR system will not operate normally:
If the vehicle runs out of AdBlue®, the vehicle speed is restricted in steps to prevent contaminants from being exhausted. When the remaining distance-to-empty reaches 0 km (0 miles) in the final stage, the engine cannot restart. For replenishment of the AdBlue® supply, consult an expert repairer, we recommend an Authorised Mazda Repairer.
Use a Mazda genuine product or a product conforming to ISO22241-1 for AdBlue®. If incompatible AdBlue® is used, the SCR system may not operate normally. In addition, the use of incompatible AdBlue® may be subject to fines and penalties. For the recommended AdBlue®, consult the nearest expert repairer, we recommend an Authorised Mazda Repairer.
-
When the remaining distance-to-empty is 1400 km (869.9 miles) or shorter while the AdBlue® warning indication is displayed, the SCR warning light turns on and the vehicle speed is restricted. In addition, if there is a problem with the SCR system/AdBlue® and the remaining distance-to-empty is 700 km (435 miles) or shorter, the SCR warning light flashes and the vehicle speed is restricted.
-
AdBlue® needs to be replenished periodically according to the scheduled maintenance information. If a warning message is displayed in the multi-information display or the SCR warning light flashes, consult an expert repairer, we recommend an Authorised Mazda Repairer.
-
Normally, the vehicle can be driven about 12,000 km (7,500 miles) before AdBlue®needs to be replenished.
