Chrysler 2005 Sebring Coupe - Manual (Page 168)

At low altitude locations, shift at the vehicle speeds listed
for acceleration. Earlier upshifts during cruise conditions
(relatively steady speeds) will result in increased fuel
economy.

Downshifting
It is recommended that you downshift to a lower gear
according to the table as necessary to maintain desired
speeds.
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 grade.
Downshifting is also important to avoid “lugging” the
engine at too low a speed, such as when turning a corner
or when driving up a steep grade.
