Engine Coolant Temperature Gage; Tire Pressure Light - Hummer H2 2009 Owner's Manual

Engine Coolant Temperature Gage

United States
This gage shows the engine coolant temperature.
It also provides an indicator of how hard the vehicle is
working. During a majority of the operation, the gage
reads 210°F (100°C) or less. If the vehicle is pulling a
load or going up hills, it is normal for the temperature to
fluctuate and approach the 250°F (122°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 5-33.

Tire Pressure Monitoring System.
