Driving with the Paddle Shifters
The transmission control system
monitors the accelerator pedal use
and your driving conditions. When
you press the accelerator pedal as in
the 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).
When the transmission returns to
drive mode (D), the displayed gear
number goes out.
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 change shift if:
You downshift before the engine
speed reaches the upper limit 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 lower limit of
the higher gear.
You press both paddle shifters at
the same time.
You press one of the two paddle
shifters with another paddle
shifter being pressed.
The transmission downshifts to first
gear and returns to drive mode (D)
when the vehicle comes to a
complete stop and 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).
