Vehicle Damage Warnings
Also, in this book you w i l l find these blue notices:
I
NOTICE
In the blue 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. In this manual, we've used
the familiar words and colors that General Motors has used for years.
You'll also see warning labels on your vehicle. They use the same colors,
and the words CAUTION or NOTICE.
