Selective Catalytic Reduction (SCR) System
Selective Catalytic Reduction (SCR) System (Some Models)
The SCR system is designed to reduce nitrogen oxide (NOx) in the exhaust gas and purify the exhaust gas by injecting it with AdBlue®.
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.
When the remaining AdBlue® is low, a message is displayed on the multi-information display, and the SCR warning light turns on/flashes.
Refer to Selective Catalytic Reduction (SCR) System Indications (Search).
In this case, consult an Authorised Mazda Dealer. If AdBlue® needs to be replenished, add AdBlue® following the specified procedure.
Refer to AdBlue® Replenishment (Search).
-
AdBlue® needs to be replenished periodically according to the scheduled maintenance information.
-
Normally, the vehicle can be driven about 12,000 km (7,500 miles) before AdBlue® needs to be replenished. However, it may need to be replenished earlier depending on the driving and environmental conditions (such as putting a high load on the engine while driving or driving the vehicle at high altitudes).
-
The sound of the SCR system operating may be heard from the area under the vehicle, however, this does not indicate a problem.
