Engine Coolant
Temperature Gauge
Metric
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 you are pulling a load or going up
hills, it is normal for the temperature
to fluctuate and approach the 122°C
(250°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 10‑20.
If the vehicle is a hybrid, see the
hybrid supplement for more
information.
