Cadillac CTS - Manual (Page 214)

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
