vehicle. At slow speeds or when
traveling down a gentle slope,
the engine is stopped
* and the
electric motor (traction motor) is
used.
*: When the hybrid battery (traction battery) requires charging or the
engine is warming up, etc., the
gasoline engine will not automati-
cally stop. ( P. 7 6 )
■During normal driving
The gasoline engine is predomi-
nantly used. The electric motor
(traction motor) charges the
hybrid battery (traction battery)
as necessary.
■When accelerating sharply
When the accelerator pedal is
depressed heavily, the power of
the hybrid battery (traction bat-
tery) is added to that of the gas-
oline engine via the electric
motor (traction motor).
■When braking (regenera-
tive braking)
The wheels operate the electric
motor (traction motor) as a
power generator, and the hybrid
battery (traction battery) is
charged.
■Regenerative braking
●In the following si tuations, kinetic
energy is converted to electric
energy and deceleration force can
be obtained in conjunction with
the recharging of the hybrid bat-
tery (traction battery).
• The accelerator pedal is released while driving with the shift lever in D or S.
• The brake pedal is depressed while driving with t he shift lever in
D or S.
■Conditions in which the gaso-
line engine may not stop
The gasoline engine starts and
stops automatically. However, it may
not stop automatic ally in the follow-
ing conditions:
●During gasoline engine warm-up
●During hybrid battery (traction bat-
tery) charging
●When the temperature of the
hybrid battery (traction battery) is
high or low
●When the heater is switched on
●When the “TOW HA UL” switch is
on
●When the “MTS” switch is on
●When the front-wheel drive control
switch is in “4H” or “4L”
●When the hood is opened during
“READY” indicator is illuminated
●When the shift lever is shifted to S
Depending on the circumstances,
the gasoline engine may also not
stop automatically in other situa-
tions.
■Charging the hybrid battery
(traction battery)
As the gasoline engine charges the
hybrid battery (trac tion battery), the
battery does not need to be charged
from an outside source. However, if
the vehicle is left parked for a long
time the hybrid battery (traction bat-
tery) will slowly dis charge. For this
reason, be sure to drive the vehicle
at least once every few months for
at least 30 minutes or 10 miles (16
km). If the hybrid battery (traction
battery) becomes fully discharged
and you are unabl e to start the
hybrid system, contact your Toyota
dealer.

■Charging the 1 2-volt battery
 P. 5 4 0
■After the 12-volt battery has dis-
charged or when the terminal
has been removed and installed
during exchange, etc.
The gasoline engine may not stop
even if the vehicle is being driven by
the hybrid battery (traction battery).
If this continues for a few days, con-
tact your Toyota dealer.
■Sounds and vibrations specific
to a Hybrid Electric Vehicle
There may be no engine sound or
vibration even though the vehicle is
able to move with the “READY” indi-
cator is illuminated. For safety, apply
the parking brake and make sure to
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 malfunc-
tion:
●Motor sounds may be heard from
the engine compartment.
●Sounds may be heard from the
hybrid battery (traction battery)
under the rear seats when the
hybrid system starts or stops.
●Relay operating sounds such as a
snap or soft clank will be emitted
from the hybrid battery (traction
battery), under the rear seats,
when the hybrid system is started
or stopped.
●Sounds may be heard from the
transmission when the gasoline
engine starts or stops, when driv-
ing 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 dep ressed or as
the accelerator pedal is released.
●Vibration may be felt when the
gasoline engine starts or stops.
●Cooling fan sounds may be heard
from the air intake vents on the
both sides of th e behind the sec-
ond seat.
■Maintenance, repair, recycling,
and disposal
Contact your Toyota dealer regard-
ing maintenance, repair, recycling
and disposal. Do n ot dispose of the
vehicle yourself.
When the gasoline engine is off
while driving, a sound is pro-
duced to warn pedestrians, peo-
ple riding bicycles or other
people and vehicles in the sur-
rounding area that the vehicle is
approaching. The pitch of the
sound adjusts according to vehi-
cle speed. When vehicle speed
is approximately 22 mph (35
km/h) or more, the warning sys-
tem turns off.
■Acoustic vehicle alerting sys-
tem
In the following cases, the acoustic
vehicle alerting system sound may
be difficult for pedestrians, people
riding bicycles or other people and
vehicles in the surrounding area to
hear:
