Reset the system whenever the
engine oil is changed so that the
system can calculate the next
engine oil change. To reset the
system:
1. Turn the ignition to ON/RUN with
the engine off.
2. Fully press and release the
accelerator pedal three times
within five seconds.
If the Change Engine Oil Soon
message is not on, the system is
reset.
The system is reset when the
Change Engine Oil Soon message
is off.
Used engine oil contains elements
that can be unhealthy for your skin
and could even cause cancer. Do
not let used oil stay on your skin.
Clean your skin and nails with soap
and water, or a good hand cleaner.
Wash or properly dispose of clothing
or rags. See the manufacturer's
warnings about the use and
disposal of oil products.
Used oil can be a threat to the
environment. If you change your
own oil, be sure to drain all the oil
from the filter before disposal. Never
dispose of oil by putting it in the
trash, pouring it on the ground, into
sewers, or into streams or bodies of
water. Recycle it by taking it to a
place that collects used oil.
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 the
dealer/retailer service department
and have it repaired as soon as
possible.
There is a special procedure for
checking and changing the
transmission fluid. Because this
procedure is difficult, it should be
done at the dealer/retailer service
department. Contact your dealer/
retailer for additional information or
the procedure can be found in the
service manual. To purchase a
service manual, see
