Understanding your SelectShift
Automatic transmission
E163184
Your vehicle is equipped with a SelectShift
Automatic transmission gearshift lever.
The SelectShift Automatic transmission
gives you the ability to change gears up or
down without a clutch.
In order to prevent the engine from running
at too low an RPM, which may cause it to
stall, SelectShift still automatically make
some downshifts if it has determined that
you have not downshifted in time.
Although SelectShift makes some
downshifts for you, it still allows you to
downshift at any time as long as the
SelectShift determines that damage to
the engine does not occur from
over-revving.
SelectShift does not upshift, even if the
engine is approaching the RPM limit. It
must be shifted manually by pressing the
+ button.
Note: Engine damage may occur if you
maintain excessive engine revving without
shifting.
The SelectShift Automatic transmission
feature has two modes: PRS and M mode.
Progressive Range Selection - PRS
Progressive Range Selection gives you the
ability to lockout gears from the automatic
shifting range. This may provide you with
an improved driving experience (for
example, in slippery conditions or when
experiencing a steep grade).
With the gearshift lever in drive (D), press
the button to active PRS. The available
and selected gears are indicated on the
instrument cluster.
All available gears display with the current
gear indicated. Press the button again to
lock out gears beginning with the highest
gear. Example: press the button twice to
lock out 6th and 5th gears. Only the
available gears display and the
transmission automatically shifts between
the available gears. Press the + button to
unlock gears to allow the transmission to
shift to higher gears. The transmission
shifts automatically within the gear range
you select.
Manual (M)
Moving the gearshift lever to the manual
(M) position allows you to manually select
the gear you desire. Only the current gear
displays. Use the buttons on the gearshift
lever to manually select gears. Press the
+ button to upshift or the button to
downshift. Return the transmission to a
different gearshift position to deactivate
manual control.
