This vehicle is equipped with an
electronic transmission. The

When the vehicle is stopped, press
ENGINE START/STOP to turn off
the vehicle. The transmission will
shift to P (Park) automatically.
The vehicle will not shift into
P (Park) if it is moving too fast. Stop
the vehicle and shift into P (Park).

out of Park 0 189.

R (Reverse) to D (Drive),
or D (Drive) to R (Reverse) while the
