Stabilitrak Indicator Light; Engine Coolant Temperature Gage - GMC 2008 Sierra 1500 Pickup Owner's Manual

®
StabiliTrak Indicator Light
If the warning light does not come on then, have it fixed
so it will be ready to warn you if there is a problem.
If it stays on, or comes on when you are driving, there
may be a problem with your StabiliTrak
and your vehicle may need service. When this warning
light is on, the system is off and will not limit wheel
spin. Adjust your driving accordingly.
This light will also flash when the StabiliTrak
is active.
®
If the StabiliTrak system warning light comes on and
stays on for an extended period of time when the system
is turned on, your vehicle needs service. See StabiliTrak
System on page 4-5 for more information.
If equipped, this warning
light should come on
briefly when the engine is
started.

Engine Coolant Temperature Gage

United States
This gage shows the engine coolant temperature.
It also provides an indicator of how hard your vehicle is
working. During a majority of the operation, the gage
will read 210°F (100°C) or less. If you are pulling a load
or going up hills, it is normal for the temperature to
fluctuate and go over the 235°F (113°C) mark. If the
gage reaches the 260°F (125°C) mark, it indicates that
®
the cooling system is working beyond its capacity.
See Engine Overheating on page 5-26.
