electric vehicle
Because there is no engine sound or vibra-
tion, it is easy to mistake the electric vehicle

always shift the shift position to P and apply
the parking brake when parked.
Before and after the EV system is started,
the following sounds and vibrations may
occur. However, these sounds and/or vibra-
tions are not signs of malfunctions:

●
be heard from the front of the vehicle
when the driver's door is opened.

Motor sounds may be heard from the
motor compartment or luggage com-
partment.

●
