WARNING
■While driving
The driver should pay extra attention to pedestrians when the v ehicle is
powered only by the electric motor (traction motor). As there is no engine
noise, the pedestrians may misjudge the vehicle’s movement. Even though
the vehicle is equipped with the vehicle proximity notification system, drive
with care as pedestrians in the vicinity may still not notice the vehicle if the
surrounding area is noisy.
