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 the Engine Oil Life System, a computer
system that indicates when to change the engine oil
and filter. This is based on engine revolutions and
engine temperature, and not on 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.
When the system has calculated that oil life has been
diminished, it indicates that an oil change is necessary.
A CHANGE OIL SOON message comes on. SeeDIC
Warnings and Messages
on page 4‑40. Change the
oil as soon as possible within the next 600 miles
(1 000 km). 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 3,000 miles (5 000 km) 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. Turn the ignition to ON/RUN, with the engine off.
2. Press the information and reset buttons on the Driver Information Center (DIC) at the same time to
enter the personalization menu. See DIC Vehicle
Personalization on page 4‑45.
3. Press the information button to scroll through the available personalization menu modes until the
DIC display shows OIL‐LIFE RESET.
4. Press and hold the reset button until the DIC display shows ACKNOWLEDGED. This will tell you
the system has been reset.
5. Turn the key to LOCK/OFF.

For vehicles with the 2.2L (VIN Code V) or 2.4L
(VIN Code B) engines, you can also reset the system
as follows:1. Turn the ignition key to ON/RUN with the engine off.
2. Fully press and release the accelerator pedal slowly three times within five seconds.
3. Turn the key to LOCK/OFF, then start the engine.
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.
Engine Air Cleaner/Filter
When to Inspect the Engine Air Cleaner/
Filter
Inspect the air cleaner/filter at the scheduled
maintenance intervals and replace it at the first oil
change after each 80 000 km (50,000 mi) interval. See
Scheduled Maintenance
on page 7‑3for more
information. If you are driving in dusty/dirty conditions,
inspect the filter at each engine oil change. Replace
filter if appears dusty or dirty.
How to Inspect the Engine Air Cleaner/
Filter
See Engine Compartment Overviewon page 6‑14for
the location of the engine air cleaner/filter.
To inspect the air cleaner/filter remove the filter from the
vehicle and lightly shake the filter to release loose dust
and dirt. If the filter remains caked with dirt, a new filter
is required. Never use compressed air to clean the filter.
Because this operation can be a little difficult, you may
choose to have this done at the dealer service
department.

If no coolant is visible in the coolant recovery tank, add
coolant at the pressure cap as follows:
1. Remove the pressurecap when the cooling
system, including the
pressure cap and
upper radiator hose,
is no longer hot.
Turn the pressure cap slowly counterclockwise.
If you hear a hiss, wait for that to stop. A hiss
means there is still some pressure left to be
vented.
2. Then keep turning the pressure cap and remove it.
3. Add the proper DEX-COOL coolant mixture to the coolant fill port, up to the base of the port. See
Engine Coolant
on page 6‑24Engine Coolant for
more information about the proper coolant mixture. 4. Rinse or wipe any spilled coolant from the engine
and the compartment.
5. Then fill the coolant recovery tank to the COLDFILL (A) line.
6. Put the cap back on the coolant recovery tank, but leave the pressure cap off.
7. Start the engine and let it run until you can feel the upper radiator hose getting hot. Watch out for the
engine cooling fan.
