This gage shows the engine coolant temperature.
It also provides an indicator of how hard your vehicle is
working. During the 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 approach the 250°F
(122°C) mark. When the gage reads greater than 250°F
(122"C), the HOT COOLANT TEMP light will be
illuminated in the message center and a chime will
sound continuously. If the gage reaches the 260°F
(125°C) mark, it indicates that the cooling system is
working beyond its capacity.

Your vehicle is equipped with a computer which
monitors operation of the fuel, ignition and emission
control systems.
This system is called OBD II (On-Board
Diagnostics-Second Generation) and is intended to
assure that emissions are at acceptable levels for the
life of the vehicle, helping to produce a cleaner
environment. The CHECK ENGINE light comes on to
indicate that there is a problem and service is required.
Malfunctions often will be indicated by the system
before any problem is apparent. This may prevent more
serious damage to your vehicle. This system is also
designed to assist your service technician in correctly
diagnosing any malfunction.
