This message displays when the automatic transmission is in manual mode. See Manual Mode for more information.
TRANSMISSION HOT IDLE ENGINE
Notice: Do not drive the vehicle while the transmission fluid is overheating and the transmission temperature warning is displayed on the instrument panel cluster and/or DIC, or the transmission can be damaged. This could lead to costly repairs that would not be covered by the warranty.
This message displays along with four chimes if the transmission fluid in the vehicle gets hot. Driving with the transmission fluid temperature high can cause damage to the vehicle. Stop the vehicle and let it idle to allow the transmission to cool. This message clears and the chime stops when the fluid temperature reaches a safe level.
