Functions
: If one of the doors is ajar, this light will
appear next to that door on the vehicle outline.
CHANGE OIL SOON: This light will appear when
the system indicates that it’s time for an oil change.
The system predicts remaining oil life using inputs from
length of drives, coolant temperature, engine rpm and
vehicle speed. It alerts you to change the oil on a
schedule consistent with the vehicle’s driving
conditions. After changing the oil, the system must be
reset. See “How to Reset the GM Oil Life System ”
in the Index.

on and the fluid in the washer fluid container is low.
AJAR: This light alerts you that the trunk is not
fully closed.
LOW TRAC: This light will come on when the
enhanced traction system is limiting wheel spin.
See “Enhanced Traction System” or “Low Traction
Light” in the Index.
TRAC OFF: This light lets you know that the enhanced
traction system has been disabled and will not limit
wheel spin. See “Enhanced Traction System Warning
Light” or “Low Traction Light” in the Index.
TRAC: If the vehicle has the enhanced traction system,
you will have a disable button on the far right side of the
DIC. The enhanced traction system is automatically
activated when you turn the ignition on. This button will
activate/deactivate the system. If you need to disable the
system, such as when you are stuck and are rocking the
vehicle back and forth, push this button. See “Stuck: In
Sand, Mud, Ice or Snow” in the Index.
