If you skip a gear when you downshift, you

more than one gear at a time when you
downshift.
This chart shows when to shift to the next gear for the
best fuel economy.

One to Four Shift Light
(Manual Transmission)
When this light comes on,
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.
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.
This light will come on when:
• The engine coolant temperature is higher than
169°F (76°C),
• you are going 15 to 19 mph (24 to 31 km/h) and
• you are 21 percent throttle or less.
