Operation
When the gear selector is in the AutoStick position (beside
the DRIVE position), it can be moved forward and rear-
ward. This allows the driver to manually select the trans-
mission gear being used. Moving the gear selector forward
(-) triggers a downshift, and rearward (+) an upshift. The
current gear is displayed in the instrument cluster.
NOTE: In AutoStick mode, the transmission will only shift
up or down when the driver moves the gear selector
rearward (+) or forward (-), except as described below.
The transmission will automatically upshift when nec-
essary to prevent engine overspeed.
The transmission will automatically downshift as the
vehicle slows (to prevent engine lugging) and will
display the current gear.
The transmission will automatically downshift to first or
second gear (depending on model) when coming to a
stop. After a stop, the driver should manually upshift (+)
the transmission as the vehicle is accelerated.
You can start out (from a stop) in first or second gear.
Starting out in second gear can be helpful in snow or icy
conditions. Tap the gear selector forward or rearward to
select the desired gear after the vehicle is brought to a
stop.
If a requested downshift would cause the engine to
overspeed, that shift will not occur.
The system will ignore attempts to upshift at too low of
a vehicle speed.
Avoid using speed control when AutoStick is engaged
because the transmission will not shift automatically.
Transmission shifting will be more noticeable when
AutoStick is enabled.
The system may revert to automatic shift mode if a fault
or overheat condition is detected.
To disengage AutoStick mode, return the gear selector to
the DRIVE position. You can shift in or out of the AutoStick
position at any time without taking your foot off the
accelerator pedal.
