How to Reset the Engine Oil Life
System
The Engine Oil Life System calculates when to change
the engine oil and lter based on vehicle use.
Whenever the oil is changed, reset the system so it can
calculate when the next oil change is required. If a
situation occurs where you change the oil prior to a
change engine oil light or CHANGE OIL SOON message
being turned on, reset the system.
After changing the engine oil, reset the system:
Vehicles with Driver Information Center (DIC)
1. Press the option button on the DIC until
ENGINE OIL MONITOR appears on the
DIC screen.
2. Press the set/reset button to reset the system.
The next screen indicates that the CHANGE
OIL SOON message has been reset.
If the vehicle has the uplevel DIC, when the
gages button is pressed and the OIL
LIFE REMAINING mode appears, it should
read 100 percent OIL LIFE REMAINING.
3. Turn the key to LOCK/OFF.
Vehicles without Driver Information Center (DIC)
1. With the engine off, turn the ignition key to
ON/RUN.
2. Fully press and release the accelerator pedal
slowly three times within ve seconds.
3. Turn the key to LOCK/OFF, then start the
vehicle.
If the light or message comes back on when you start
your vehicle, the oil life system has not reset. Repeat the
procedure.
What to Do with Used Oil
Used engine oil contains certain elements that can be
unhealthy for your skin and could even cause cancer.
Do not let used oil stay on your skin for very long. Clean
your skin and nails with soap and water, or a good hand
cleaner. Wash or properly dispose of clothing or rags
containing used engine oil. 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
lter 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. Instead, recycle it by taking
it to a place that collects used oil. If you have a problem
properly disposing of used oil, ask your dealer/retailer, a
service station, or a local recycling center for help.

How to Add Coolant to the Cooling
System (3.6L V6 Engine)
Notice:The engine has a specic cooling system
drain and ll procedure. Failure to follow this
procedure could cause the engine to overheat and
be severely damaged. If the engine’s cooling system
needs to be drained and re-lled, please see the
dealer/retailer.
1. You can remove the
pressure cap 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 that there is still some pressure left.2. Then keep turning the pressure cap and remove it.{CAUTION:
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol
and it will burn if the engine parts are hot
enough. Do not spill coolant on a hot engine.
3. Fill the cooling system with the proper DEX-COOL
®
coolant mixture, up to the base of the ller neck.
SeeEngine Coolant on page 5-27for more
information about the proper coolant mixture.
4. Rinse or wipe any spilled coolant from the engine
and the compartment.
