CHANGE ENGINE OIL

This message is displayed when the engine oil needs to
be changed. See GM Oil Life System previously in
this section for information on how to reset the message.
This message will clear itself after 10 seconds until
the next ignition cycle. See Scheduled Maintenance on
page 6-4 for more information.

CHECK TIRE PRESSURE

If your vehicle is equipped with the tire pressure monitor
system, and a low tire pressure is detected in any of
the vehicle's tires, this message will appear on the DIC.
Press the select button, or reset stem, to acknowledge
the message and clear it from the DIC display. It
will appear at each ignition cycle until the tires are
inflated to the correct inflation pressure.

CHECK WASHER FLUID

If the washer fluid level is low, this message will appear
on the DIC. Adding washer fluid will clear the message.
Pressing the select button will acknowledge this
message and clear it from the DIC display. This
message will clear itself after 10 seconds until the next
ignition cycle.

CHECK OIL LEVEL

If the oil level in the vehicle is low, this message will
appear on the DIC. Check the oil level and correct it as
necessary. You may need to let the vehicle cool or
warm up and cycle the ignition to be sure this message
will clear. Once the problem is corrected, pressing
the select button will clear this message from the DIC
display. This message will clear itself after 10 seconds
until the next ignition cycle.

DRIVER DOOR AJAR

If the driver's door is not fully closed and the vehicle is
in a drive gear, this message will appear on the
display and you will hear a chime. Stop and turn off the
vehicle, check the door for obstacles, and close the
door again. Check to see if the message still appears on
the DIC. Pressing the select button will acknowledge
this message and clear it from the DIC display.

ENGINE COOLANT HOT

If the cooling system temperature gets hot, this message
will appear in the DIC. Stop the vehicle and let the
engine idle in PARK (P) to allow the coolant to reach a
safe temperature. This message will clear when the
coolant temperature drops to a safe operating
temperature.
