Upshifting
For the best fuel economy and performance in using your man-
ual transaxle, upshift as listed below.
At low altitude locations, shift at the vehicle speeds listed.
Upshifting earlier during cruise conditions (relatively steady
speeds) will improve your fuel economy.

Downshifting
It is recommended that you downshift to a lower gear when
needed to maintain the desired speed, according to the table.
Avoid downshifting at too high a speed. The engine may suffer
damage.
To maintain a safe speed and prolong brake life, shift down to
2nd or 1st when descending a steep hill.
Downshifting is also important to avoid "lugging" the engine
at too low a speed, such as when turning a corner or when driv-
ing up a steep hill.
Recommended downshifting speed
Downshifting speed
Under 20 mph (32 km/h)
20 to 30 mph (32 to 48 km/h)
