indicate the need for vehicle service
for up to a year. The engine oil and
filter must be changed at least once

be reset. Your trained dealer
technician can perform this work.
If the engine oil life system is reset
accidentally, service the vehicle
within 5 000 km/3,000 mi since the

system when the oil is changed.
