An Emission Control Service.
When the “Change Engine Oil
Soon” message displays, service is
required for the vehicle as soon as
possible, within the next 1 000 km/
600 miles. If driving under the best
conditions, the engine oil life system
might not indicate the need for
vehicle service for more than a year.
The engine oil and filter must be
changed at least once a year and
the oil life system must be reset.
Your dealer/retailer has trained
service technicians who will perform
this work and reset the system.
If the engine oil life system is reset
accidentally, service the vehicle
within 5 000 km/3,000 miles since
the last service. Reset the oil life
system whenever the oil is changed.
