M (Manual)
M is the manual shift mode position.
Gears can be shifted up or down by
operating the selector lever.
Refer to Manual Shift Mode on page
4-38.
▼Shift Position Indication
1. Shift position indication

The selector position is indicated when
the ignition is switched ON.
Gear position indication
In manual shift mode, the “M” of the
shift position indication illuminates
and the numeral for the selected gear
is displayed.
▼ Active Adaptive Shift (AAS)
Active Adaptive Shift (AAS)
automatically controls the transmission
shift points to best suit the road
conditions and driver input. This
improves driving feel. The transmission
may switch to AAS mode when driving
up and down slopes, cornering, driving
at high elevations, or depressing the
accelerator pedal quickly while the
selector lever is in the D position.
Depending on the road and driving
conditions/vehicle operations, gear
shifting could be delayed or not occur,
however, this does not indicate a
problem because the AAS mode will
maintain the optimum gear position.
Manual Shift Mode
▼ Manual Shift Mode
The manual shift mode gives you the
feel of driving a manual transmission
vehicle by allowing you to operate the
selector lever manually. This allows you
to control engine rpm and torque to
the drive wheels much like a manual
transmission when more control is
desired.
To change to manual shift mode, shift
the lever from D to M.

NOTE
Changing to manual shift mode
while driving will not damage the
transmission.
If you change to manual shift mode
when the vehicle is stopped, the gear
will shift to M1.
If you change to manual shift mode
without depressing the accelerator
pedal when driving in D range, 5th
gear/6th gear, the gear will shift to
M4/M5.
To return to automatic shift mode, shift
the lever from M to D.
