Vehicle data recording
Your Toyota is equipped with several sophisticated computers that will record
certain data, such as:
• Engine speed
•
Electric motor speed (traction motor speed)
• Accelerator status
• Brake status
• Vehicle speed
• Shift position
• Hybrid battery (traction battery) status
The recorded data varies according to the vehicle grade level and options
with which it is equipped. Furthermore, these computers do not record con-
versations, sounds or pictures.
●Data usage
Toyota may use the data recorded in these computers to diagnose malfunc-
tions, conduct research and development, and improve quality.
Toyota will not disclose the recorded data to a third party except:
• With the consent of the vehicle owner or with the consent of the lessee if the vehicle is leased
• In response to an official request by the police, a court of law or a govern- ment agency
• For use by Toyota in a lawsuit
• For research purposes where the data is not tied to a specific vehicle or vehicle owner

CAUTION
■Hybrid battery (traction battery)
Never resell, hand over or modify the hybrid battery. To prevent accidents,
hybrid batteries that have been removed from a disposed vehicle are col-
lected through Toyota dealers. Do not dispose of the battery yourself.
Unless the battery is properly collected, the following may occur, resulting in
death or serious injury:
●The hybrid battery may be illegally disposed of or dumped, and someone
may touch a high voltage part, resulting in an electric shock.
● The hybrid battery is intended to be used exclusively with your hybrid vehi-
cle. If the hybrid battery is used outside of your vehicle or modified in any
way, accidents such as electric shock, heat generation, smoke generation,
an explosion and electrolyte leakage may occur.
When reselling or handing over your vehicle, the possibility of an accident is
extremely high because the person receiving the vehicle may not be aware
of these dangers.
■ Disposal of the hybrid battery (traction battery)
If your vehicle is disposed of without the hybrid battery having been
removed, there is a danger of serious electric shock if high voltage parts,
cables and their connectors are touched. In the event of that your vehicle
must be disposed of, the hybrid battery must be disposed of your Toyota
dealer or a qualified service shop. If the hybrid battery is not disposed of
properly, they may cause electric shock that can result in death or serious
injury.

Before driving
■
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 R.
■ 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
● During low or high hybrid battery (traction battery) temperature
● When the heater is switched on
■ Charging the hybrid battery (traction 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.
■ During normal driving
The gasoline engine is predominantly used. The electric motor
(traction motor) charges the hybrid 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 braking)
The electric motor (traction mo tor) charges the hybrid battery
(traction battery).

36 1-1. Hybrid system
●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.
● To help prevent the 12-volt battery from becoming discharged, drive the
vehicle at least once a month, and operate the accessories only when
the “READY” indicator is on. When parking the vehicle, make sure the
doors is closed and all lights are turned off.
■ Charging the 12-volt battery
P. 600
■ 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 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 or 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.

Before driving
High voltage components
Take care when handling the hybrid sy stem, as it contains a high volt-
age system (about 650 V at maximum) as well as parts that become
extremely hot when the hybrid system is operating. Obey the caution
labels attached to the vehicle.
■ Maintenance, repair, recycling, and disposal
Contact your Toyota dealer regarding maintenance, repair, recycling and
disposal. Do not dispose of the vehicle yourself.

■Hybrid battery air vents
There are air intake vents under
the second seats to cool the
hybrid battery (traction battery).
If the vents become blocked, the
hybrid battery may overheat,
leading to a reduction in hybrid
battery output.
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 multi-infor-
mation display (P. 39) and the
navigation system screen ( P.
39, 41). The following images
are examples only, and may vary
slightly from actual conditions.
