Caution
Use only engine oil that is
approved to the dexos
specification or an equivalent
engine oil of the appropriate
viscosity grade. Engine oils
approved to the dexos
specification will show the dexos
symbol on the container. Failure to
use the recommended engine oil
or equivalent can result in engine
damage not covered by the vehicle
warranty. If you are unsure
whether the oil is approved to the
dexos specification, ask your
service provider.
SAE 5W-30 is the best viscosity
grade for the vehicle. SAE 0W-30,
0W-40, or 5W-40 can also be used.
Do not use other viscosity oils such
as SAE 10W-30, 10W-40, or
20W-50.
In an area of extreme cold, where the
temperature falls below -29C
(-20F), an SAE 0W-30 oil should be
used. An oil of this viscosity grade
will provide easier cold starting for
the engine at extremely low
temperatures. When selecting an oil
of the appropriate viscosity grade, be
sure to always select oil that meets
the required specification.
Engine oil life system
This vehicle has a computer system
that indicates when to change the
engine oil and filter. This is based on
engine revolutions, engine
temperature and mileage. Based on
driving conditions, the mileage at
which an oil change is indicated can
vary considerably. For the oil life
system to work properly, the system
must be reset every time the oil is
changed.
Vehicle care 299
When the system has calculated that
oil life has been diminished, it
indicates that an oil change is
necessary. A change engine oil lamp
displays. Change the oil as soon as
possible within the next 1,000 km
(600 miles). 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 miles) since the
last oil change.
