Hybrid system
Your vehicle is a hybrid vehicle. It has characteristics different from
conventional vehicles. Be sure you are closely familiar with the char-
acteristics of your vehicle, and operate with care.
The hybrid system combines a gasoline engine and an electric
motor (traction motor) according to driving conditions, improving
fuel efficiency and reducing exhaust emissions.
Gasoline engine
Electric motor (Traction motor)

Regenerative braking
The motor generator converts kinetic energy to electric energy when:
● The accelerator pedal is released.
● The brake pedal is depressed with the shift lever in “D” or “B”.
■ 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:
● The gasoline engine is warming up.
● The hybrid battery (traction battery) is being charged.
● The hybrid battery (traction battery) temperature is low or high.
■ When stopped/during take-off
The gasoline engine stops when the vehicle is stopped. During
take-off, the electric motor (traction motor) drives the vehicle. At
slow speeds or when traveling down a gentle slope, the engine
is stopped and the motor is used.
■ During normal driving
The gasoline engine is predominantly used. The electric motor
(traction motor) charges the hybr id battery (traction battery) as
necessary.
■ When accelerating sharply
The power of the hybrid battery (traction battery) is added via
electric motor (traction motor) to that of the gasoline engine.
■ When braking (Regenerative brake)
The electric motor (traction mo tor) charges the hybrid battery
(traction battery).

■Charging the battery
● As the gasoline engine charges the hybrid battery (traction 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 will slowly dis-
charge. For this reason, be sure to drive the vehicle at least once every
several months for at least 30 minutes or 10 miles (16 km). If the hybrid
battery becomes fully discharged and you are unable to jump-start the
vehicle with the 12 volt battery, contact your Toyota dealer.
● If the shift lever is in “N”, the hybrid battery (traction battery) will not be
charged. When driving in heavy traffic, operate the vehicle with the shift
lever in “D” to avoid discharging the battery.
■ After the 12 volt battery has di scharged or has been changed or
removed
The gasoline engine may not stop even if the vehicle is running on the hybrid
battery (traction battery). If this continues for a few days, contact your Toyota
dealer.

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 put the shift lever in “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) behind
the rear seat when the hybrid system starts or stops.
● Sounds from the hybrid system may be heard when the back door lid is
open.
● Sounds may be heard from the transmission when the hybrid system
starts or stops.
● Engine sounds may be heard when accelerating sharply.
● Sounds may be heard from the regenerative brake when you press the
brake pedal.
● Vibration may be felt when the gasoline engine starts or stops.
● You may hear cooling fan sounds coming from the air intake vents behind
the rear seat.
■ Maintenance, repair, recycling, and disposal
Contact your Toyota dealer regarding maintenance, repair, recycling and dis-
posal. Do not dispose of the vehicle yourself.

High voltage componentsTake care when handling the hybrid sy stem, as it contains a high volt-
age system (about 500V at maximum) as well as parts that become
extremely hot when the hybrid system is operating. Obey the caution
labels attached to the vehicle. Air conditioning compressor

Hybrid battery air vent
Hybrid battery air vent
There is an air intake vent on the
side of the rear right seatback for
the purpose of cooling the hybrid
battery (traction battery). If the
vent becomes blocked, the hybrid
battery may overheat, leading to
a reduction in hybrid battery out-
put.
Emergency shut off system
The emergency shut off system blocks off the high voltage current
and stops the fuel pump to minimize the risk of electrocution and fuel
leakage when a certain level of impact is detected by the impact sen-
sor. If the emergency shut off syste m activates, your vehicle will not
restart. To restart the hybrid system, contact your Toyota dealer.
Energy monitor/consumption screen
You can view the status of your hybrid system on the touch screen
(  P. 182). The following images are examples only, and may vary
slightly from actual conditions.
