◆When stopped/during start off
The gasoline engine stops* when the vehicle is stopped. During
start off, the electric motor (traction motor) drives the vehic le. At
slow speeds or when traveling down a gentle slope, the engine i s
stopped* and the electric motor (traction motor) is used.
When shift lever is in N, the hybrid battery (traction battery) is not
being charged.
*: When the hybrid battery (traction battery) requires charging o r the engine
is warming up, etc., the gasoline engine will not automatically stop.
( P. 120)
◆During normal driving
The gasoline engine is predominantly used. The electric motor
(traction motor) charges the hybrid battery (traction battery) as nec-
essary.
◆When accelerating sharply
When the accelerator pedal is depressed heavily, the power of t he
hybrid battery (traction battery) is added to that of the gasol ine
engine via the electric motor (traction motor).
◆When braking (regenerative braking)
The wheels operate the electric motor (traction motor) as a pow er
generator, and the hybrid battery (traction battery) is charged .
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 25 km/h (15 mph).

■Regenerative braking
● In the following situations, kinetic energy is converted to electric energy and
deceleration force can be obtained in conjunction with the rech arging of the
hybrid battery (traction battery).
• The accelerator pedal is released while driving with the shift lever in D, B
(2ZR-FXE engine) or S (M20A-FXS engine).
• The brake pedal is depressed while driving with the shift leve r in D, B
(2ZR-FXE engine) or S (M20A-FXS engine).
● While the GPF system (P. 531) is operating to regenerate the exhaust gas
filter, the hybrid battery (traction battery) may not be rechar ged.
■ EV indicator
■ Conditions in which the gasoline engine may not stop
The gasoline engine starts and stops automatically. However, it may not stop
automatically in the following conditions*:
● During gasoline engine warm-up
● During hybrid battery (traction battery) charging
● When the temperature of the hybrid battery (traction battery) is high or low
● When the heater is switched on
*: Depending on the circumstances, the gasoline engine may also not stop
automatically in situations other than those above.
■ Charging the hybrid battery (traction battery)
As the gasoline engine charges the hybrid battery (traction bat tery), the bat-
tery does not need to be charged from an outside source. Howeve r, if t h e
vehicle is left parked for a long time the hybrid battery (trac tion battery) will
slowly discharge. For this reason, be sure to drive the vehicle at least once
every few months for at least 30 minutes or 16 km (10 miles). If the hybrid
battery (traction battery) becomes fully discharged and you are unable to start
the hybrid system, contact any authorized Toyota retailer or To yota authorized
repairer, or any r eliable repairer.
The EV indicator comes on when the
vehicle is driven using only the electric
motor (traction motor) or the gasoline
engine is stopped.

■ Charging the 12-volt battery
 P. 752
■ After the 12-volt battery has discharged or when the terminal has been
removed and installed during exchange, etc.
The gasoline engine may not stop even if the vehicle is being d riven by the
hybrid battery (traction battery). If this continues for a few days, contact any
authorized Toyota retailer or Toyota authorized repairer, or an y reliable
repairer.
■ Sounds and vibrations specific to a Hybrid Electric Vehicle
There may be no engine sound or vibration even though the vehic le is able to
move with the “READY” indicator is illuminated. For safety, app ly 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 sy stem 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) 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), behind the rear seats, when the hybrid sys-
tem is started or stopped.
● Sounds from the hybrid system may be heard when the back door 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 when the gasoline engine starts or stops.
● Cooling fan sounds may be heard from the air intake vent. (P. 124)

■ Maintenance, repair, recycling, and disposal
Contact any authorized Toyota retailer or Toyota authorized rep airer, or any
reliable repairer regarding maintenance, repair, recycling and disposal. Do
not dispose of the vehicle yourself.
■ Acoustic vehicle alerting system
In the following cases, the acoustic vehicle alerting system ma y be difficult for
surrounding people to hear.
● In very noisy areas
● In the wind or the rain
Also, as the acoustic vehicle alerting system is installed on t he front of the
vehicle, it may be more difficult to hear from the rear of the vehicle compared
to the front.

Hybrid system precautions
The illustration is an example for explanation and may differ from the
actual item.
Take care when handling the hybrid system, as it is a high volt -
age system (about 600 V*1 or 650 V*2 at maximum) as well as
contains parts that become extremely hot when the hybrid sys-
tem is operating. Obey the warning labels attached to the vehi-
cle.

There is an air intake vent under
the right side of the rear seat for
the purpose of cooling the hybrid
battery (traction battery). If the
vent becomes blocked, it may
cause the input-output of the
hybrid battery (traction battery) to
be limited.
When a certain level of impact is detected by the impact sensor , the
emergency shut off system blocks the high voltage current and s tops
the fuel pump to minimize the risk of electrocution and fuel le akage. If
the emergency shut off system activates, your vehicle will not restart.
To restart the hybrid system, contact any authorized Toyota ret ailer or
Toyota authorized repairer, or any reliable repairer.
A message is automatically displayed when a malfunction occurs in
the hybrid system or an improper operation is attempted.
If a warning message is shown on
the multi-information display, read
the message and follow the
instructions.

■If a warning light comes on, a warning message is displayed, or the
12-volt battery is disconnected
The hybrid system may not start. In this case, try to start the system again. If
the “READY” indicator does not come on, contact any authorized To y o t a
retailer or Toyota authorized repairer, or any reliable repaire r.
■ Running out of fuel
When the vehicle has run out of fuel and the hybrid system cann ot be started,
refuel the vehicle with at leas t enough gasoline to make the low fuel level
warning light ( P. 685) go off. If there is only a small amount of fuel, the
hybrid system may not be able to start. (The standard amount of fuel is about
7.5 L [2.0 gal., 1.7 Imp.gal.], when the vehicle is on a level surface. This value
may vary when the vehicle is on a slope. Add extra fuel when th e vehicle is
inclined.)
■ Electromagnetic waves
● High voltage parts and cables on Hybrid Electric Vehicles incorporate elec-
tromagnetic shielding, and therefore emit approximately the sam e amount
of electromagnetic waves as conventional gasoline powered vehic les or
home electronic appliances.
● Your vehicle may cause sound interference in some third party-produced
radio parts.
■ Hybrid battery (traction battery)
The hybrid battery (traction battery) has a limited service lif e. The lifespan of
the hybrid battery (traction battery) can change in accordance with driving
style and driving conditions.

tem. DC and AC high voltage is very dangerous and can cause sev ere
burns and electric shock that may result in death or serious in jury.
● Never touch, disassemble, remove or replace the high voltage parts,
cables or their connectors.
● The hybrid system will become hot after starting as the system uses high
voltage. Be careful of both the high voltage and the high tempe rature, and
always obey the warning labels attached to the vehicle.
● Never try to open the service plug
access hole located under the right side
of the rear seat. The service plug is
used only when the vehicle is serviced
and is subject to high voltage.
