Vehicle Engine Control Unit Reset Procedure - Mazda CX-8 Manual

New Zealand
Mazda recommends using Mazda Motor Oil which has been specifically designed and
tested to meet the stringent Mazda Engineering Standards (MES) for your Mazda. To ensure
engine longevity is not compromised particularly under the harsh climatic conditions
existing in New Zealand, we only recommend using genuine Mazda engine oil which is
available throughout the Mazda Repairer network.
If Mazda Motor Oil is not selected for use, always use an engine oil meeting the
specifications.
NOTE
Whenever the engine oil is replaced, the vehicles engine control unit needs to be reset as
•
soon as possible. Otherwise the wrench indicator light or engine oil warning light may
turn on. To reset the engine control unit, consult an expert repairer, we recommend an
Authorised Mazda Repairer or refer to the vehicle engine control unit reset procedure on
page 6-15.
Inspect the engine oil level periodically. When inspecting the engine oil, if the engine oil
•
level is exceeds the "X" mark on the dipstick, replace the engine oil. This should be done
by an expert repairer, we recommend an Authorised Mazda Repairer. When replacing the
engine oil, inspect the oil level using the oil dipstick and refill so that the engine oil level
is within the range between MIN and MAX as shown in the figure.

may turn on earlier than normal.
NOTE
The initialization (engine oil data resetting) of the recorded value can be performed using
