DRIVE (D)
This range should be used for most city and highway
driving. It provides the smoothest upshifts and down-
shifts, and the best fuel economy. The transmission
automatically upshifts through all forward gears. The
DRIVE position provides optimum driving characteris-
tics under all normal operating conditions.
When frequent transmission shifting occurs (such as
when operating the vehicle under heavy loading condi-
tions, in hilly terrain, traveling into strong head winds, or
while towing a heavy trailer), use the AutoStick shift
control (refer to AutoStick in this section for further
information) to select a lower gear. Under these condi-
tions, using a lower gear will improve performance and
extend transmission life by reducing excessive shifting
and heat buildup.
During extremely cold temperatures (-22°F [-30°C] or
below), transmission operation may be modified depend-
ing on engine and transmission temperature as well as
vehicle speed. Normal operation will resume once the
transmission temperature has risen to a suitable level.
MANUAL (M)
The MANUAL (M, +/-) position (beside the DRIVE
position) enables full manual control of transmission
shifting (also known as AutoStick mode; refer to
"AutoStick" in this section for further information). Tog-
gling the shift lever forward (-) or rearward (+) while in
the MANUAL (AutoStick) position will manually select
the transmission gear, and will display the current gear in
the instrument cluster.
