Chevrolet 2000 Corvette Owner's Manual page 87

This chart shows when to shift to the next higher gear
for the best fuel economy.
If your engine speed drops below 900 rpm, or if the
engine is not running smoothly, you should downshift to
the next lower gear. You may have to downshift two or
more gears to keep the engine running smoothly or for
good engine performance.
NOTICE:
When you are shifting gears, don't move the
gearshift lever around needlessly. This can damage
parts of the transmission and may require costly
repair. Shift directly into the next appropriate gear.
One to Four Shift Light
(Manual Transmission)
You must complete the shift into FOURTH (4) to
deactivate 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:
Do not try to force the shift lever into SECOND (2)
or THIRD (3) when the 1 TO 4 SHIFT light
comes on. Do not try to re
starting to shift into FOURTH (4). You will damage
your transmission. Shift only from FIRST (1) to
FOURTH (4) when the light comes on.
When this light comes on,
you can only shift from
FIRST (1) to FOURTH (4)
instead of FIRST (1) to
SECOND (2).
