OnStar service is subject to the
OnStar Terms and Conditions
included in the OnStar Glove
Box Kit.
OnStar service requires wireless
communication networks and the
Global Positioning System (GPS)
satellite network. Not all OnStar
services are available everywhere
or on all vehicles at all times.OnStar service can’t work unless
the vehicle is in a place where
OnStar has an agreement with
a wireless service provider for
service in that area, and the
wireless service provider has
coverage, network capacity,
reception, and technology
compatible with OnStar service.
Service involving location
information about the vehicle
can’t work unless GPS signals
are available, unobstructed,
and compatible with the OnStar
hardware. The vehicle has to have
a working electrical system and
adequate battery power for the
OnStar equipment to operate.
OnStar service may not work if the
OnStar equipment isn’t properly
installed or you haven’t maintained
it and the vehicle is in good working
order and in compliance with
all government regulations.

5-18 Instruments and Controls
English
This gauge shows the engine
coolant temperature.
It also provides an indicator of
how hard the vehicle is working.
During a majority of the operation, the gauge reads 100°C (210°F) or
less. If pulling a load or going up
hills, it is normal for the temperature
to fluctuate and go over the 113°C
(235°F) mark. If the gauge reaches
the 125°C (260°F) mark, it indicates
that the cooling system is working
beyond its capacity.
See
Engine Overheating on
page 10‑25.
If the vehicle is a hybrid, see the
hybrid supplement for more
information.
Voltmeter Gauge
This gauge indicates the battery
voltage when the ignition is
turned on.
When the ignition is on, this gauge
indicates the battery voltage.
