For conditions 1 and 2, this warning will flash five
times and the display will then show the tire
pressure gage. For condition 3, this warning will
flash continuously until the driver acknowledges it.
In any of the three cases, the warning will
redisplay every 10 minutes until the situation is
corrected. Conditions 2 and 3 will also display a
warning light elsewhere on the cluster that will stay
on after this warning is acknowledged. See
Tire
Pressure Light (CTS-V Only) on page 201 for more

System on page 405 for more information on tire

One-to-Four Shift Message
(CTS-V Only)
This message indicates
that you can only shift
from FIRST (1) to
FOURTH (4) instead of
FIRST (1) to
SECOND (2).
You must complete the shift into FOURTH (4) to
turn off this feature. This helps you get the
best possible fuel economy.
After shifting to FOURTH (4), you may downshift
to a lower gear if you prefer.
See Manual Transmission Operation on page 122
for more information.
Notice: Forcing the shift lever into any gear
except FOURTH (4) when the 1 TO 4 SHIFT
message comes on may damage the
transmission. Shift only from FIRST (1) to
FOURTH (4) when the light comes on.
