Transmission Fluid Hot Message When you see this flashing symbol, the transmission fluid temperature is high (290°F (143°C)). To acknowledge this warning, press either button on the outboard switch on the left spoke of the steering wheel. After you press this button, the warning will redisplay every 10 minutes until the temperature returns to the normal operating range. If this message appears, you may continue to drive at a slower speed while monitoring the transmission fluid temperature. Ideally, the transmission oil temperature should not rise above 265°F (129°C). If you regularly experience temperatures above this limit due to high performance operation, it is recommended to use an auxiliary fluid cooler for the transmission and differential. See your dealer for details. If this warning is displayed during normal vehicle operation on flat roads, your vehicle may need service. See your dealer for an inspection. See DIC Warnings and Messages on page 228 and Manual Transmission Fluid on page 355 for more information. 214
