■ Sounds and vibrations specific to a hybrid vehicle
There may be no engine sounds or vibration even though the vehicle is able to
move. Always shift the shift lever to P when parked.
The following sounds or vibrations may occur when the hybrid system is operating,
and are not a malfunction:
● Motor sounds may be heard from the engine compartment.
● Sounds may be heard from the hybrid battery (traction battery) under the rear
seat when the hybrid system starts or stops.
● Sounds from the hybrid system may be heard when the back door is open.
● Sounds may be heard from the hybrid transmission when the engine is started
or stopped, or while the engine is idling.
● Engine sounds may be heard when accelerating sharply.
● Sounds may be heard due to regenerative braking when the brake pedal is
depressed and accelerator is loosened.
● Vibration may be felt when the gasoline engine starts or stops.
● Cooling fan sounds may be heard from the air intake vents under the rear seat.
■ Vehicle Proximity Notification System
In the following cases, the Vehicle Proximity Notification System sound may be diffi-
cult for pedestrians, people riding bicycles or other people and vehicles in the sur-
rounding area to hear:
● When there is a lot of noise in the vicinity
● When it is raining or during strong winds
● When in the area surrounding the rear of the vehicle, rather than in front of the
vehicle
