an oil change is not necessary for up
to a year. The engine oil and filter
must be changed at least once a year
and, at this time, the system must be
reset. Your dealer has trained service
people who will perform this work and
reset the system. It is also important
to check the oil regularly over the
course of an oil drain interval and
keep it at the proper level.
If the system is ever reset accidentally,
the oil must be changed at 5 000 km
(3,000 mi) since the last oil change.
Remember to reset the oil life system
whenever the oil is changed.
After you change the oil, the oil life
system will need to be reset. See your
dealer for service.
See OIL LIFE REMAINING under
Driver Information Centre (DIC) 0 129
for information on the engine oil life
system.

Fluid

How to Check Automatic
Transmission Fluid
It is not necessary to check the
transmission fluid level.
A transmission fluid leak is the only
reason for fluid loss. If a leak occurs,
take the vehicle to your dealer and
have it repaired as soon as possible.
The vehicle is not equipped with a
transmission fluid level dipstick.
There is a special procedure for
checking and changing the
transmission fluid. Because this
procedure is difficult, this should be
done at the dealer. Contact the dealer
for additional information.
Change the fluid and filter at the
intervals listed in Scheduled

the fluid listed in Recommended Fluids
and Lubricants 0 318.
