Buick 2007 LaCrosse - Manual (Page 189)

Engine Coolant Temperature Gage
The vehicle has a gage
that shows the engine
coolant temperature.
If the gage pointer moves towards the H, the
engine is too hot.
This reading indicates the same thing as the
warning light. It means that the engine coolant has
overheated. If the vehicle has been operating
under normal driving conditions, pull off the road,
stop the vehicle, and turn off the engine as
soon as possible. See Engine Overheating on
page 367.
Low Coolant Warning Light
If your vehicle has this
light, it comes on briefly
when you turn your
ignition on as a
bulb check only.
