PERFORMANCE & MAINTENANCE
6-Speed Automatic Transmission
Controls (if equipped)
The 6-speed automatic transmission has
a Range Selection Mode feature that
enables the driver to select the range
of gears desired for the current driving
conditions, such as when driving on
downhill grades.
To use this feature, move the shift lever
to the Manual (M) position and select a
lower or higher driving gear using the
+ / – button on the shift lever. The
display on the
instrument panel
cluster will show
the current gear
selection.
The transmis-
sion will be limit-
ed to the gear selected and lower gears.
Gears higher than the gear selected will
not be available.
If current vehicle speed is too high or
too low for the requested gear, the shift
will not occur.
