Engine Oil Life System
When to Change Engine Oil
Your vehicle has a computer system that lets you know
when to change the engine oil and lter. This is based on
engine revolutions and engine temperature, and not on
mileage. Based on driving conditions, the mileage
at which an oil change will be indicated can vary
considerably. For the oil life system to work properly, you
must reset the system every time the oil is changed.
When the system has calculated that oil life has been
diminished, it will indicate that an oil change is necessary.
A CHANGE OIL SOON message in the Driver
Information Center (DIC) will come on. SeeDIC Warnings
and Messages on page 3-40. Change your oil as soon
as possible within the next 600 miles (1 000 km). It is
possible that, if you are driving under the best conditions,
the oil life system may not indicate that an oil change is
necessary for over a year. However, your engine oil and
lter must be changed at least once a year and at this
time the system must be reset. Your dealer has
GM-trained service people who will perform this work
using genuine GM parts and reset the system. It is also
important to check your oil regularly and keep it at the
proper level.
If the system is ever reset accidentally, you must
change your oil at 3,000 miles (5 000 km) since your
last oil change. Remember to reset the oil life system
whenever the oil is changed.
How to Reset the Engine Oil Life
System
The Engine Oil Life System calculates when to change
your engine oil and lter based on vehicle use. Anytime
your oil is changed, reset the system so it can calculate
when the next oil change is required. If a situation occurs
where you change your oil prior to a CHANGE OIL SOON
message being turned on, reset the system.
After changing the engine oil, the system must be reset
as follows:
1. Turn the ignition to RUN, with the engine off.
2. Press the information and reset buttons on the DIC
at the same time to enter the personalization menu.
SeeDIC Vehicle Personalization on page 3-43.
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.
If the CHANGE OIL SOON message comes back on
when you start your vehicle, the engine oil life system
has not reset. Repeat the reset procedure.
