How to Reset the AdBlue Warning Light on a Mazda CX7

Model: Mazda Cx 7 MK 1 - Years 2006-2012
Part: AdBlue warning light

To reset the SCR warning light (which corresponds to the AdBlue light), after refilling the vehicle with the required additive, get in the car, close all four doors, and turn on the ignition. Go to the "settings" menu and select "preferences"; the vehicle will alert you to a malfunction in the SCR system. Turn off the ignition. Remove the fuse that protects this function. The fuse box is located between the steering column and the driver's door. The fuse to remove is number 5 in the first row, or the second from the right; it is a 10 Amp fuse. Now turn the ignition back on. Turn off the ignition again and replace the fuse. The warning light is now off.
