HIGHLANDER_HV_U (OM48F12U)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. These computers do not record conversations or
sounds, and only record images outside of the vehicle in certain situati\
ons.
●Data Transmission
Your vehicle may transmit the data re corded in these computers to Toyota
without notification to you.
●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 law suit
• For research purposes where the data is not tied to a specific vehicle or vehicle owner
●Usage of data collected through Safety Connect (U.S. mainland only)
If your Toyota has Safety Connect and if you have subscribed to those ser-
vices, please refer to the Safety Connect Telematics Subscription Service
Agreement for information on data collected and its usage.

Hybrid system features
Your vehicle is a hybrid vehicle. It has characteristics different
from conventional vehicles. Be sure you are closely familiar with
the characteristics of your vehicle, and operate it with care.
The hybrid system combines the use of a gasoline engine and
an electric motor (traction moto r) according to driving condi-
tions, improving fuel efficien cy and reducing exhaust emis-
sions.

◆When stopped/during start off
The gasoline engine stops
* when the vehicle is stopped. During
start 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 electric motor (traction motor) is used.
When the shift lever is in N, the hybrid battery (traction battery) is
not being charged.
*: When the hybrid battery (traction battery) requires charging or the engine is warming up, etc., the gasoline engine will not automatically
stop. ( →P. 83)
◆During normal driving
The gasoline engine is predomin antly 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 the
hybrid battery (traction battery) is added to that of the gasoline
engine via the electric motor (traction motor).
◆When braking (regenerative braking)
The wheels operate the electric motor (traction motor) as a power
generator, and the hybrid battery (traction battery) is charged.
When the gasoline engine is off while driving, a sound is produced to
warn pedestrians, people riding bi cycles or other people and vehicles
in the surrounding area that the vehi cle is approaching. The pitch of
the sound adjusts according to vehi cle speed. When vehicle speed is
approximately 16 mph (25 km/h) or more, the warning system turns
off.

■Regenerative braking
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 battery).
●The accelerator pedal is released while driving with the shift lever in D or S\
.
● The brake pedal is depressed while driving with the shift lever in D or S.
■ 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
■ Charging the hybrid battery (traction battery)
As the gasoline engine charges the hybrid battery (traction battery), the bat-
tery 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 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 10 miles (16 km). If the hybrid
battery (traction battery) becomes fully discharged and you are unable to start
the hybrid system, contact your Toyota dealer.
●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 t he vehicle, make sure the doors are
closed and all lights are turned off.
■ Charging the 12-volt battery
→P. 628
■ After the 12-volt battery has dischar ged 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, contact your
Toyota dealer. The EV indicator comes on when the
vehicle is driven using only the electric
motor (traction motor) or the gasoline
engine is stopped.

Sounds and vibrations specific to a hybrid vehicle
There may be no engine sound or vibration even though the vehicle is able to
move with the “READY” indicator is illuminated. 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 t\
he
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), 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 vents under the rear\
seat.
■ Vehicle Proximity Notification System
In the following cases, the Vehicle Proximity Notification System sound may
be difficult for pedestrians, people ridi ng bicycles or other people and vehicles
in the surrounding area to hear:
● When there is a lot of noise in the vicinity
● When it is raining or during strong winds
● When in the area surrounding the rear of the vehicle, rather than in front of
the vehicle
■ Maintenance, repair, recycling, and disposal
Contact your Toyota dealer regarding maintenance, repair, recycling and dis-
posal. Do not dispose of the vehicle yourself.
■ Customization
Settings (e.g. on/off operation of the EV indicator) can be changed.
