M (Manual)
With the gearshift lever in M (Manual), the driver can change gears up
or down as desired. This is called SelectShift Automatic™ transmission
(SST) mode. By moving the gearshift lever from drive position D (Drive)
to M (Manual), you now have control of selecting the gear you desire
using buttons on the shift lever. Only the current gear will be displayed.
Press the + button or the – button to upshift or downshift. If the –
button is pressed at a vehicle speed that would cause an engine
overspeed, the requested gear will flash then disappear and the
transmission will remain in the current gear.
To return to normal D (Drive) position, move the shift lever back from M
to D.
The transmission will operate in gears one through six.
Recommended shift speeds
Upshift according to the following chart:
Upshifts when accelerating
1 – 2
2 – 3
3 – 4
4 – 5
5 – 6
In order to prevent the engine from running at too low an RPM, which
may cause it to stall, the SST will still automatically make some
downshifts if it has determined that you have not downshifted in time.
Although the SST will make some downshifts for you, it will still allow
you to downshift at any time as long as the SST determines that the
engine will not be damaged from over-revving.
The SST will not automatically upshift, even if the engine is approaching
the RPM limit. It must be shifted manually by pressing the + button.
Engine damage may occur if excessive engine revving is held
without shifting.
If your vehicle gets stuck in mud or snow
If your vehicle gets stuck in mud or snow, it may be rocked out by
shifting between forward and reverse gears, stopping between shifts in a
steady pattern. Press lightly on the accelerator in each gear.
