When to Change Engine Oil (GM Oil Life System) Your vehicle has a computer system that lets you know 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 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 ENGINE OIL message will come on. Change your oil as soon as possible within the next two times you stop for fuel. 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 filter 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. 5-20 How to Reset the CHANGE ENGINE OIL Message The GM Oil Life System calculates when to change your engine oil and filter 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 ENGINE OIL message being turned on, reset the system. To reset the CHANGE ENGINE OIL message, see "GM Oil Life System" under DIC Operation and Displays on page 3-56 for vehicles equipped with the DIC, or do the following: 1. Turn the ignition key to RUN with the engine off. 2. Fully press and release the accelerator pedal slowly three times within five seconds. If the OIL LIFE RESET message flashes for 10 seconds, the system is resetting. 3. Turn the key to LOCK. If the CHANGE ENGINE OIL message comes back on when you start your vehicle, the engine oil life system has not reset. Repeat the procedure. If it still does not reset, see your dealer for service.

When to Change Engine Oil

(GM Oil Life System)

Your vehicle has a computer system that lets you know

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 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 ENGINE OIL message will

come on. Change your oil as soon as possible within

the next two times you stop for fuel. 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 filter 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 CHANGE ENGINE OIL

your engine oil and filter 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

reset the system.

To reset the CHANGE ENGINE OIL message,

see “GM Oil Life System” under

DIC Operation and

Displays on page 3-56

for vehicles equipped with

the DIC, or do the following:

1. Turn the ignition key to RUN with the engine off.

2. Fully press and release the accelerator pedal slowly

three times within five seconds.

If the OIL LIFE RESET message flashes for

10 seconds, the system is resetting.

3. Turn the key to LOCK.

If the CHANGE ENGINE OIL message comes back on

when you start your vehicle, the engine oil life system

has not reset. Repeat the procedure. If it still does

not reset, see your dealer for service.
