Engine oil temperature gauge

The engine oil temperature gauge displays the oil temperature from 100 to 320°F

(40 to 160°C). When the oil temperature exceeds 284°F (140°C), a buzzer will

sound and the bar display will blink in red and white to inform the driver that the

oil temperature is abnormally high and that the performance and lifespan of the

oil is severely compromised. Allowing the engine oil to cool and maintain a stable

temperature helps to stabilize its performance.

During high-speed driving: approximately 176

to 194°F (80 to 90°C)

[Outside air temperature approximately 68°F

(20°C)]

Blinks when temperature exceeds

284°F (140°C)

An oil temperature sensor is installed near the oil filter to monitor the temperature

of the engine oil supplied by the oil pump. The ECU processes the engine oil

temperature from this sensor and informs the driver using the engine oil temperature

gauge.
