Caution
Do not drive the vehicle while the

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 a
chime 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.
