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 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.
