Driving with the Paddle Shifters (Automatic Transmission Only)
The transmission control system
monitors the accelerator pedal use
and your driving conditions. When
you press the accelerator pedal as
in normal driving, the system
judges that you are driving at a
constant cruising speed without
using the paddle shifters. Under
these conditions, D-paddle shift
mode is canceled, and the
transmission automatically returns
to drive mode (D).
Hold the ＋ paddle shifter for 2
seconds to return to drive mode (D).
When the transmission returns to
drive mode (D), the displayed gear
number disappears.
The transmission remains in the
selected gear if you do not accelerate.

Each time you pull either paddle
shifter, the transmission shifts one
gear up or down. If you want to shift
up or down more than two gears, pull
the paddle shifter twice, pause, and
then pull it again.
The automatic transmission will not
allow you to shift up or down if:
You downshift before the engine
speed reaches the highest
threshold of the lower gear.
If you try to do this, the gear
position indicator will flash the
number of the lower gear several
times, then return to a higher gear.
You upshift before the engine
speed reaches the lowest
threshold of the higher gear.
You pull both paddle shifters at
the same time.

You are trying to downshift from
second to first with the accelerator
pedal off.
When you depress the accelerator
pedal to the floor, the transmission
will downshift from second to first.
The transmission downshifts to first
gear and returns to drive mode (D)
when the vehicle comes to a
complete stop or the vehicle speed is
about 6 mph (10 km/h).
If there is a problem in the
transmission while you are driving
with the paddle shifters, the D
indicator flashes, the D-paddle
shift mode is canceled, and the
transmission returns to drive
mode (D).
