Non-Air conditioning type

The cooling fan operates in single stage. The engine control module (ECM) controls the cooling fan according to the coolant temperature, and vehicle speed.

Vehicle speed [km/h (mph)]	Coolant temperature [°C (°F)]	Cooling fan operation
V < 45 (28)	95 ~ 100 (203 ~ 212) or above	On
45 (28) < or = V < 80 (49.7)	95 ~ 100 (203 ~ 212) or above	On
80 (49.7) < or = V	105 (221) or above	On
