When driving with the gasoline engine stopped, a sound, which changes in accordance with
the driving speed, will be played in order to warn people nearby of the vehicle’s approach.
The sound will stop when the vehicle speed exceeds approximately 22 mph (35 km/h).
If the shift position is in N, the hybrid battery (traction battery) will not be charged. To help
prevent the battery from discharging, avoid leaving the N position selected for an extended
period of time.
In the following situations, kinetic energy is converted to electric energy and deceleration
force can be obtained in conjunction with the recharging of the hybrid battery (traction bat-
tery).
● The accelerator pedal is released while driving with the shift position in D or M.
● The brake pedal is depressed while driving with the shift position in D or M.
Because there is no engine sound or vibration, it is easy to mistake the hybrid electric vehi-
cle for being off when it is actually still running, as indicated by the “READY” indicator being
illuminated. For safety, make sure to always shift the shift position to P and apply the parking
brake 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.
● Relay operating sounds such as a snap or soft clank will be emitted from the hybrid bat-
tery (traction battery), behind the rear seats, when the hybrid system is started or
stopped.
● Sounds may be heard from the hybrid battery (traction battery) behind the rear seats
when the hybrid system starts or stops.
● Sounds from the hybrid system may be heard when the trunk lid is open.
● Sounds may be heard from the transmission when the gasoline engine starts or stops,
when driving at low speeds, or during idling.
● Engine sounds may be heard when accelerating sharply.
● Sounds may be heard due to regenerative braking when the brake pedal is depressed or
as the accelerator pedal is released.
● Vibration may be felt or sounds may be heard when the gasoline engine starts or stops.
● Cooling fan sounds may be heard from the air intake vents on the both sides of the rear
seatback.
