■When installing a booster seat
To prevent the belt from going into ALR lo ck mode, do not fully extend the shoulder
belt. ALR mode causes the belt to tighten only . This could cause injury or discomfort to
the child. ( →P. 3 3 )
■When installing a child restraint system
Follow the directions given in the child restraint system installation manual and fix the
child restraint system securely in place.
If the child restraint system is not correctly fixed in place, the child or other passengers
may be seriously injured or even killed in the event of sudden braking, sudden swerving
or an accident.
●When a booster seat is installed, always en sure that the shoulder belt is positioned
across the center of the child’s shoulder. The belt should be kept away from the child’s
neck, but not so that it could fall off the child’s shoulder. Failing to do so may result in
death or serious injury in the event of sudden braking, sudden swerving or an acci-
dent.
●Ensure that the belt and plate are securely locked and the seat belt is not twisted.
●Shake the child restraint system left and right, and forward and backward to ensure
that it has been securely installed.
●After securing a child restraint system, never adjust the seat.
●Follow all installation instructions provided by the child restraint system manufacturer.
●If the driver’s seat interferes with the child
restraint system and prevents it from being
attached correctly, attach the child restraint
system to the right-hand rear seat.
●Adjust the front passenger seat so that it does
not interfere with the child restraint system.
●Only put a forward-facing child restraint sys-
tem on the front seat when unavoidable.
When installing a forward-facing child
restraint system on the front passenger seat,
move the seat as far back as possible even if
the “AIR BAG OFF” indicator light is illumi-
nated. Failure to do so may result in death or
serious injury if the airbags deploy (inflate).

■Do not use a seat belt extender
If a seat belt extender is used when installing a child restraint system, the seat belt will
not securely hold the child restraint system, which could cause death or serious injury
to the child or other passengers in the event of sudden braking, sudden swerving or an
accident.
■To correctly attach a child restraint system to the anchors
When using the LATCH anchors, be sure that there are no foreign objects around the
anchors and that the seat belt is not caught behind the child restraint system. Make sure
the child restraint system is securely attached , or it may cause death or serious injury to
the child or other passengers in the event of a sudden stop, sudden swerve or accident.

Exhaust gas precautions
Harmful substance to the hu man body is included in exhaust gases if inhaled.
WA R N I N G
Exhaust gases include harmful carbon monoxide (CO), which is colorless and odorless.
Observe the following precautions.
Failure to do so may cause exhaust gases enter the vehicle and may lead to an accident
caused by light-headedness, or may lead to death or a serious health hazard.
■Important points while driving
●Keep the back door closed.
●If you smell exhaust gases in the vehicle even when the back door is closed, open the
windows and have the vehicle inspected at your Lexus dealer as soon as possible.
■When parking
●If the vehicle is in a poorly ventilated area or a closed area, such as a garage, stop the
hybrid system.
●Do not leave the vehicle with the hybrid system on for a long time.
If such a situation cannot be avoided, park the vehicle in an open space and ensure
that exhaust fumes do not enter the vehicle interior.
●Do not leave the hybrid system operating in an area with snow build-up, or where it is
snowing. If snowbanks build up around the vehicle while the hybrid system is operat-
ing, exhaust gases may collect and enter the vehicle.
■Exhaust pipe
The exhaust system needs to be checked period ically. If there is a hole or crack caused
by corrosion, damage to a joint or abnormal exhaust noise, be sure to have the vehicle
inspected and repaired by your Lexus dealer.

Hybrid system features
The illustration is an example for explanation and may differ from the actual item.Gasoline engine
Electric motor (traction motor)
Your vehicle is a hybrid vehicle. It has characteristics different from conven-
tional 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 motor) according to driving conditions, improving fuel effi-
ciency and reducing exhaust emissions.

For safety and security
◆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 engi ne is stopped* and the electric motor
(traction motor) is used.
When shift position is in N, the hybrid battery (traction battery) is not charged.
When the vehicle is stopped, always put the shift position to P.
Also, even in heavy traffic conditions, drive the vehicle in D or B.
*: When the hybrid battery (traction battery) requires charging or the engine is warm- ing up, etc., the gasoline engine will not automatically stop. ( →P. 6 6 )
◆During normal driving
The gasoline engine is predominantly 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 bat-
tery (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 as a power generator, and the hybrid
battery (traction battery) is charged.
When driving with the ga soline 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 15 mph (25 km/h).

■Regenerative braking
In the following situations, kinetic energy is converted to electric energy and decelera-
tion force can be obtained in conjunction with the recharging of the hybrid battery (trac-
tion battery).
●The accelerator pedal is released while driving with the shift position in D or B.
●The brake pedal is depressed while driving with the shift position in D or B.
■EV indicator
■Conditions in which the gasoline engine may not stop
The gasoline engine starts and stops automatically. However, it may not stop automati-
cally 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 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 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 becomes fully discharged and you are unable to start the hybrid system,
contact your Lexus dealer.
■Charging the 12-volt battery
→P. 5 6 3
■After the 12-volt battery has discharged or has been changed or removed
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 Lexus 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. For sa fety, apply the parking brake and make sure
to shift the shift position 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) behind the rear seats
when the hybrid system starts or stops.
●Relay operating sounds such as a snap or so ft clank will be emitted from the hybrid bat-
tery (traction battery), behind the rear se ats, when the hybrid system is started or
stopped.
●Sounds may be heard from the transmission when the gasoline engine starts or stops,
when driving at low sp eeds, 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.
●Operating sounds or motor sounds that occur when the brake pedal is operated.
●Vibration may be felt when the gasoline engine starts or stops.
●Cooling fan sounds may be heard from the air intake vent on the side of rear right seat-
back.
■Vehicle proximity notification system
In the following cases, the vehicle proximity notification system may be difficult for sur-
rounding people to hear.
●In very noisy areas
●In the wind or the rain
Also, as the vehicle proximity notification system is installed on the front of the vehicle, it
may be more difficult to hear from the rear of the vehicle compared to the front.
■Maintenance, repair, recycling, and disposal
Contact your Lexus dealer regarding maintenance, repair, recycling and disposal. Do
not dispose of the vehicle yourself.
■Customization Settings
Settings (e.g. on/off operation of the EV indicator) can be changed.

For safety and security
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, lead-
ing to a reduction in hybrid battery out-
put.
When a certain level of impact is detected by the impact sensor, the emergency
shut off system blocks the high voltage current and stops the fuel pump to mini-
mize the risk of electrocution and fuel leakage. If the emergency shut off system
activates, your vehicle will not restart. To restart the hybrid system, contact your
Lexus dealer.
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.
