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) as desired.
In order to prevent the engine from running
at too low an RPM, which may cause it to
stall, SelectShift will still automatically
make some downshifts if it has determined
that you have not downshifted in time.
Although SelectShift will make some
downshifts for you, it will still allow you to
downshift at any time as long as the
SelectShift determines that damage will
not be caused to the engine from
over-revving.
SelectShift will not automatically 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.

Transmission
The SelectShift Automatic transmission
feature has two modes: PRS and M mode.
(If Equipped)
PRS (Progressive Range Selection)
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 will 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 will display and the
transmission will automatically shift
between the available gears. Press the +
button to unlock gears to allow the
transmission to shift to higher gears. The
transmission will shift automatically within
the gear range you select.
Manual (M)
Moving the gearshift lever to the manual
(M) position will allow you to manually
select the gear you desire. Only the current
gear will display. 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.
