Dic Warnings And Messages; Check Tire Pressure - GMC 2008 Yukon Denali Owner's Manual

DIC Warnings and Messages

Messages are displayed on the DIC to notify the driver
that the status of the vehicle has changed and that
some action may be needed by the driver to correct the
condition. Multiple messages may appear one after
another.
Some messages may not require immediate action, but
you can press any of the DIC buttons on the instrument
panel or the trip odometer reset stem on the instrument
panel cluster to acknowledge that you received the
messages and to clear them from the display.
Some messages cannot be cleared from the DIC
display because they are more urgent. These messages
require action before they can be cleared. You should
take any messages that appear on the display seriously
and remember that clearing the messages will only
make the messages disappear, not correct the problem.
The following are the possible messages that can be
displayed and some information about them.
3-56
CHANGE ENGINE OIL SOON
This message displays when the engine oil needs to be
changed. When you change the engine oil, be sure
to reset the CHANGE ENGINE OIL SOON message.
See Engine Oil Life System on page 5-16 for information
on how to reset the message. See Engine Oil on
page 5-13 and Scheduled Maintenance on page 6-4 for
more information.

CHECK TIRE PRESSURE

This message displays when the pressure in one or
more of the vehicle's tires needs to be checked.
This message also displays LEFT FRONT, RIGHT
FRONT, LEFT REAR, or RIGHT REAR to indicate which
tire needs to be checked. You can receive more than
one tire pressure message at a time. To read the other
messages that may have been sent at the same
time, press the set/reset button or the trip odometer
reset stem. If a tire pressure message appears on the
DIC, stop as soon as you can. Have the tire pressures
checked and set to those shown on the Tire Loading
Information label. See Tires on page 5-55, Loading Your
Vehicle on page 4-34, and Inflation - Tire Pressure on
page 5-60. The DIC also shows the tire pressure values.
See "DIC Operation and Displays (Using DIC Buttons)"
earlier in this section. If the tire pressure is low, the
low tire pressure warning light comes on. See Tire
Pressure Light on page 3-41.
