Vehicle Care
When the system has calculated
that oil life has been diminished, it
indicates that an oil change is
necessary. A CHANGE ENGINE
OIL SOON message comes on. See
Engine Oil Messages on page 5 36.
Change the oil as soon as possible
within the next 1 000 km (600 mi).
It is possible that, if driving under
the best conditions, the oil life
system might indicate that 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
monitor will need to be reset. See
your dealer for service.
See OIL LIFE REMAINING under
Driver Information Centre (DIC) on
page 5 28 for information on the
engine oil life monitor.

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 the
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, it should be
done at the dealer.
Change the fluid and filter at the
intervals listed in Scheduled
Maintenance on page 11 1, and be
sure to use the fluid listed in
Recommended Fluids and
Lubricants on page 11 5.

Manual Gearbox Fluid

It is not necessary to check the
manual gearbox fluid level.
A transmission fluid leak is the only
reason for fluid loss. If a leak
occurs, take the vehicle to a dealer
for service. Have it repaired as soon
as possible. You may also have the
fluid level checked by your dealer
when the oil is changed. See
Recommended Fluids and
Lubricants on page 11 5 for the
proper fluid to use.

Hydraulic Clutch

It is not necessary to regularly
check clutch fluid unless you
suspect there is a leak in the
system. Adding fluid will not correct
