WARNING
If you skip a gear when you
downshift, you could lose control
of the vehicle. You could injure
yourself or others. Do not shift
down more than one gear at a
time when you downshift.
This chart shows when to shift to the next higher gear for the best fuel
economy.
Manual Transmission Recommended
Engine
1 to 2
All Engines 24 (15)
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.
When shifting gears, do
not move the shift lever around
unnecessarily. This may damage
the transmission. Shift directly
into the next gear.
