One to Four Shift Light
(Manual Transmission)
Instrument Panel
Cluster
When this light comes on, you can only shift from
FIRST (1) to FOURTH (4) instead of FIRST (1) to
SECOND (2). The light will be displayed on the
instrument panel cluster and a message will be
displayed on the trip computer.
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.
Notice: Forcing the shift lever into any gear except
FOURTH (4) when the 1 TO 4 SHIFT light comes
on may damage the transmission. Shift only from
FIRST (1) to FOURTH (4) when the light comes on.
