This chart shows when to shift to the next higher gear for the best fuel
economy.

If the 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 shifting gears, do
not move the shift lever around
unnecessarily. This may damage
the transmission. Shift directly
into the next gear.

One to Four Shift Light
(Manual Transmission)
When this light comes on, you can
only shift from 1 (First) to 4 (Fourth)
instead of 1 (First) to 2 (Second).
See One-to-Four Shift Light (Manual
Transmission) on page 5 21 for
more information.

Downshifting
(Manual Transmission)
Do not downshift into the gear
shown below at a speed greater
than shown in the table:
4 to 5 5 to 6
80 (50)
Notice: If you skip more than one
gear when you downshift, or if
you race the engine when you
release the clutch pedal while
downshifting, you could damage
the engine, clutch, driveshaft or
the transmission. Do not skip
gears or race the engine when
downshifting.
The six-speed transmission has a
spring that centers the shift lever
near 3 (Third) and 4 (Fourth). This
spring helps you know which gear
you are in when you are shifting. Be
