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. 
1. 
With the ignition key 
in 
RUN but the engine 
off, 
repeatedly push the tripheset button until 
OIL 
is 
displayed on  the  Driver Information Center (DIC). 
2.  Once 
OIL 
is displayed, push and hold the tripheset 
button for five seconds. The  number  will disappear 
and be replaced by 
100 
(indicating 
100% 
oil life 
remaining). 
3. 
Turn the key to 
OFF. 
If the change engine oil message  comes  back  on, 
the engine oil life monitor has not reset. Repeat the 
procedure. 
What 
to 
Do 
with 
Used 
Oil 
Used engine oil contains certain elements  that  may  be 
unhealthy for your skin  and could even  cause  cancer. 
Don’t 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 filter 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  your  used  oil, 
ask your dealer, a  service  station or a local  recycling 
center for help.
