Engine Coolant Temperature Warning Light; Engine Coolant Temperature Gage - Buick 2006 LaCrosse Owner's Manual

Engine Coolant Temperature
Warning Light
This light will come on when you first start the vehicle
as a check to let you know that the light is working. It will
go out after a few seconds. If the light does not come
on, the bulb may be burned out. See your GM dealer to
have it corrected.
If the light does not go out or if the light comes on
and stays on while you are driving, your vehicle may
have a problem with the cooling system. You should
stop the vehicle and turn off the engine as soon
as possible to avoid damage to the engine. A warning
chime will sound when this light is on, also.
See Engine Overheating on page 5-27.
3-40
This light tells you that
your engine is very hot.

Engine Coolant Temperature Gage

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 5-27.
The vehicle has a gage
that shows the engine
coolant temperature.
