GMC 1994 Yukon Owner's Manual page 9

Vehicle Damage Warnings
Also, in this book you will find these notices:
NOTICE:
These mean there is something that could damage your vehicle.
In the notice area, we tell you about something that can damage your
vehicle. Many times, this damage would not be covered by your warranty,
and it could be costly. But the notice will tell you what to do to help avoid
the damage.
When you read other manuals, you might see CAUTION and NOTICE
warnings in different colors or in different words.
You'll also see warning labels on your vehicle. They use yellow for
cautions, blue for notices and the words CAUTION or NOTICE.
