Engine Coolant Temperature Gauge

Metric

English
This gauge shows the engine coolant temperature. Under normal driving conditions the gauge will read approximately 100°C (210°F) or less. If the gauge pointer is near 125°C (260°F), the engine is too hot.
It means that the engine coolant has overheated. If the vehicle has been operating under normal driving conditions, pull off the road, stop the vehicle, and turn off the engine as soon as possible.
See Engine Overheating on page 10‑18 for more information.
