Scheduled
Maintenance
When the Change Engine Oil
Soon Message Displays
Change engine oil and filter. See
Engine Oilon page 10‑11.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 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.

Engine Oil Life System
on
page 10‑14.
