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 or 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.

Engine Oil Life System

When to Change Engine Oil
This vehicle has a computer system that
indicates when to change the engine oil and
filter. This is based on a combination of
factors which include engine revolutions,
engine temperature, and miles driven. 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.
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. 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.
How to Reset the Engine Oil Life System
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. Display the REMAINING OIL LIFE on the
DIC. See Driver Information Center (DIC)
(Uplevel) 0 108 or
Driver Information Center (DIC) (Base
Level) 0 105.
2. Press and hold the thumbwheel on the
DIC while the Oil Life display is active.
3. Confirm yes, and the oil life will change
to 100%.
Vehicle Care
The oil life system can also be reset as
follows:
1. Place the ignition in Service Mode. See
Ignition Positions 0 184.
2. Display REMAINING OIL LIFE on the DIC
menu. See Driver Information Center
(DIC) (Uplevel) 0 108 or
Driver Information Center (DIC) (Base
Level) 0 105.
3. Fully press and release the accelerator
pedal three times within five seconds.
4. If the display changes to 100%, the
system is reset.
If the CHANGE ENGINE OIL SOON message
comes back on when the vehicle is started,
the engine oil life system has not been
reset. Repeat the procedure.

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.
Change the fluid at the intervals listed in
Maintenance Schedule 0 296, and be sure to
use the transmission fluid listed in
Recommended Fluids and Lubricants 0 302.
