GMC 2007 Acadia - Manual (Page 225)

Engine Coolant Temperature Gage
This gage shows the engine coolant temperature.
Under normal driving conditions the gage will
read 210°F (100 °C) or less. If the gage pointer
is near 260°F (125 °C), the engine is too hot.
It means that your engine coolant has overheated.
If you have been operating your vehicle under
normal driving conditions, you should pull off the
road, stop your vehicle and turn off the engine
as soon as possible.
See Engine Overheating on page 410 for more
information.
