Sit the child in the child restraint 
system. Fit the seat belt to the child 
restraint system according to the 
manufacturer’s instructions and 
insert the plate into the buckle. 
Make sure that the belt is not 
twisted.

Check that the shoulder belt is correctly 

positioned over the child’s shoulder and 

that the lap belt is as low as possible. 

(

P.28)

Removing a child restraint system 
installed with a seat belt

Press the buckle release button and 
fully retract the seat belt.

When releasing the buckle, the child 
restraint system may spring up due to the 
rebound of the seat cushion. Release the 
buckle while holding down the child 
restraint system.
Since the seat belt automatically reels itself, 
slowly return it to the stowing position.

WARNING

When installing a child restraint sys-

tem

Observe the following precautions.

Failure to do so may result in death or 

serious injury.

Do not allow children to play with the 

seat belt. If the seat belt becomes 

twisted around a child’s neck, it may 

lead to choking or other serious inju-

ries that could result in death.

If this occurs and the buckle cannot be 

unfastened, scissors should be used to 

cut the belt.

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.

When a booster seat is installed, 

always ensure 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.

Follow all installation instructions pro-

vided by the child restraint system 

manufacturer.

Child restraint LATCH anchors

LATCH anchors are provided for the 
outboard rear seats. (Buttons display-
ing the location of the anchors are 
attached to the seats.)

When installing in the rear out-
board seats

Install the child restraint system in 
accordance to the operation manual 
enclosed with the child restraint sys-
tem.

1

Adjust the seat.

If there is a gap between the child seat and 

the seatback, adjust the seatback angle 

until good contact is achieved.

2

Remove the head restraint if it inter-
feres with your child restraint sys-
tem. (

P.152)

If the head restraint cannot be removed, 

WARNING

When securing some types of child 

restraint systems in rear seats, it may 

not be possible to properly use the 

seat belts in positions next to the child 

restraint without interfering with it or 

affecting seat belt effectiveness. Be 

sure your seat belt fits snugly across 

your shoulder and low on your hips. If it 

does not, or if it interferes with the 

child restraint, move to a different posi-

tion. Failure to do so may result in 

death or serious injury.

When installing a child restraint system 

in the rear center seat, adjust both seat 

cushions to the same position and 

align both seatbacks at the same 

angle. The seatbacks must be adjusted 

to the same angle. Otherwise, the 

child restraint system cannot be 

securely restrained and this may cause 

death or serious injuries in the event of 

sudden braking, sudden swerving or 

an accident.

If the seat is adjusted, reconfirm the 

security of the child restraint system.

When installing a booster seat

To prevent the belt from going into ALR 

lock mode, do not fully extend the shoul-

der belt. ALR mode causes the belt to 

tighten only. This could cause injury or 

discomfort to the child. (

P.30)

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.

system can only be installed in the out-
board seat.

Laws and regulations pertaining to 

anchors

The LATCH system conforms to 

FMVSS225 or CMVSS210.2.

Child restraint systems conforming to 

FMVSS213 or CMVSS213 specifications 

can be used.

This vehicle is designed to conform to SAE 

J1819.

ISOFIX lower anchorages (ISO-
FIX child restraint system)

Lower anchorages are provided for the 
outboard rear seats. (Buttons display-
ing the location of the anchorages are 
attached to the seats.)

WARNING

When installing a child restraint sys-

tem

Observe the following precautions.

Failure to do so may result in death or 

serious injury.

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.

Follow all installation instructions pro-

vided by the child restraint system 

manufacturer.

Never attach two child restraint system 

attachments to the same anchor. In a 

collision, one anchor may not be 

strong enough to hold two child 

restraint system attachments and may 

break.

If the LATCH anchors are already in 

use, use the seat belt to install a child 

restraint system in the center seat.

When securing some types of child 

restraint systems in rear seats, it may 

not be possible to properly use the 

seat belts in positions next to the child 

restraint without interfering with it or 

affecting seat belt effectiveness. Be 

sure your seat belt fits snugly across 

your shoulder and low on your hips. If it 

does not, or if it interferes with the 

child restraint, move to a different posi-

tion. Failure to do so may result in 

death or serious injury.

If the seat is adjusted, reconfirm the 

security of the child restraint system.

Important! Read this information about 
exposure to radio frequency signals 
before using Safety Connect;
The Safety Connect system installed in 
your vehicle is a low-power radio trans-
mitter and receiver. It receives and also 
sends out radio frequency (RF) signals.
In August 1996, the Federal Commu-
nications Commission (FCC) adopted 
RF exposure guidelines with safety lev-
els for mobile wireless phones. Those 
guidelines are consistent with the

Hybrid system features

Your vehicle is a hybrid electric 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 motor) according to driving conditions, improving fuel efficiency and 
reducing exhaust emissions.

the vehicle. At slow speeds or when 
traveling down a gentle slope, the 
engine is stopped

*

 and the electric 

motor (traction motor) is used.
RX350h: When the shift position is in

*

: When the hybrid battery (traction bat-

tery) requires charging or the engine is 
warming up, etc., the gasoline engine will 
not automatically stop. (

P.74)

During normal driving

The gasoline engine is predominantly 
used. The electric motor (traction 
motor) charges the hybrid battery 

(traction battery) as necessary.
Depending on the driving conditions, 
the rear electric motor (traction motor) 
is powered by the front electric motor 
(traction motor) to drive the rear 
wheels.

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 brak-
ing)

The wheels operate the electric motor 
(traction motor) as a power generator, 
and the hybrid battery (traction bat-
tery) is charged.

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 

(traction battery).

RX350h: The accelerator pedal is 

released while driving with the shift posi-

tion in D or S.

RX500h: The accelerator pedal is

EV indicator

The EV indicator comes on when the vehi-

cle is driven using only the electric motor 

(traction motor) or the gasoline engine is 

stopped.

Conditions in which the gasoline engine 

may not stop

The gasoline engine starts and stops auto-

matically. However, it may not stop auto-

matically in the following conditions:

During gasoline engine warm-up

During hybrid battery (traction battery) 

charging

When the temperature of the hybrid bat-

tery (traction battery) is high or low

When the heater is switched on

When the hood is opened during 

“READY” indicator is illuminated

Depending on the circumstances, the gaso-

line engine may also not stop automatically 

in other situations.

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 (traction 

battery) will slowly discharge. For this rea-

son, be sure to drive the vehicle at least 

once every few months for at least 30 min-

utes or 10 miles (16 km). If the hybrid bat-

tery (traction battery) becomes fully 

discharged and you are unable to start the 

hybrid system, contact your Lexus dealer.

Charging the 12-volt battery

P.558

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 driven by the hybrid bat-

tery (traction battery). If this continues for a 

few days, contact your Lexus dealer.

Sounds and vibrations specific to a 

hybrid electric vehicle

Because there is no engine sound or vibra-

tion, it is easy to mistake the hybrid electric 

vehicle for being off when it is actually still 

running, as indicated by the “READY” indi-

cator being illuminated. For safety, make 

sure to always shift the shift position to P 

and apply the parking brake 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 

soft clank will be emitted from the hybrid 

battery (traction battery), under the rear 

seats, when the hybrid system is started 

or stopped.

Sounds from the hybrid system may be 

75

1-4. Hybrid system

For safety and security

heard when the back door is open.

Sounds may be heard from the transmis-

sion 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 regenera-

tive 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 seats.

Maintenance, repair, recycling, and dis-

posal

Contact your Lexus dealer regarding main-

tenance, repair, recycling and disposal. Do 

not dispose of the vehicle yourself.

Customization

Some functions can be customized. 

(

P.590)

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. This 
sound may be heard inside the vehicle. 
The sound will stop when the vehicle 
speed exceeds approximately 22 mph 
(35 km/h).

When there is a long downhill slope 
along the route, the system reduces 
the hybrid battery (traction battery) 
level before reaching the slope to 
help ensure charging capacity for 
regenerative braking while travel-
ing downhill.

When traffic congestion is pre-
dicted along the route, the system 
helps ensure a certain battery level 
before reaching congested roads to 
reduce the frequency of starting the 
engine to charge the hybrid battery 
(traction battery) due to low battery 
levels.

Running out of fuel

When the vehicle has run out of fuel and the 

hybrid system cannot be started, refuel the 

vehicle with at least enough gasoline to 

make the low fuel level warning light 

(

P.519) 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 2.6 gal. [9.8 L, 2.2 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 the vehicle is 

inclined.)

Electromagnetic waves

High voltage parts and cables on hybrid 

electric vehicles incorporate electro-

magnetic shielding, and therefore emit 

approximately the same amount of elec-

tromagnetic waves as conventional gaso-

line powered vehicles or home electronic 

appliances.

Your vehicle may cause sound interfer-

ence in some third party-produced radio 

parts.

Hybrid battery (traction battery)

WARNING

High voltage precautions

This vehicle has high voltage DC and AC 

systems as well as a 12-volt system. DC 

and AC high voltage is very dangerous 

and can cause severe burns and electric 

shock that may result in death or serious 

injury.

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 temperature, and 

always obey the warning labels 

attached to the vehicle.

Never try to open the service plug 

access hole located under the rear 

seat. The service plug is used only 

when the vehicle is serviced and is 

subject to high voltage.

Road accident cautions

Observe the following precautions to 

reduce the risk of death or serious injury:

Stop the vehicle in a safe place to pre-

vent subsequent accidents. While 

depressing the brake pedal, apply the 

parking brake and shift the shift posi-

tion to P to stop the hybrid system. 

Then, slowly release the brake pedal.

Do not touch the high voltage parts, 

cables and connectors.

If electric wires are exposed inside or 

outside your vehicle, an electric shock 

may occur. Never touch exposed elec-

tric wires.

If a fluid leak occurs, do not touch the 

fluid as it may be strong alkaline elec-

trolyte from the hybrid battery (trac-

tion battery). If it comes into contact 

with your skin or eyes, wash it off 

immediately with a large amount of 

water or, if possible, boric acid solu-

tion. Seek immediate medical atten-

tion.

If a fire occurs in the hybrid electric 

vehicle, leave the vehicle as soon as 

possible. Never use a fire extinguisher 

that is not meant for electric fires. 

Using even a small amount of water 

may be dangerous.

If your vehicle needs to be towed, do 

so with all four wheels raised. If the 

wheels connected to the electric 

motor (traction motor) are on the 

ground when towing, the motor may 

continue to generate electricity. This 

may cause a fire. (

P.513)

Carefully inspect the ground under the 

vehicle. If you find that liquid has 

leaked onto the ground, the fuel sys-

tem may have been damaged. Leave 

the vehicle as soon as possible.

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 

collected through your Lexus dealer. 

Do not dispose of the battery yourself.

Unless the battery is properly col-

lected, the following may occur, result-

ing in death or serious injury:

• The hybrid battery may be illegally dis-

posed of or dumped, and it is hazard-

ous to the environment or someone 

may touch a high voltage part, result-

ing in an electric shock.

80

1-4. Hybrid system

The air intake vents for the hybrid bat-
tery (traction battery) are located 
under the rear seats.
If the air intake vents are blocked, it 

could lead to a reduction in hybrid bat-
tery (traction battery) output.

If input/output of the hybrid battery (trac-
tion battery) becomes limited and the dis-
tance that the vehicle can be driven using 
the electric motor (traction motor) is 
reduced, the fuel economy may ber-
educed.

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 minimize the risk of electrocu-

WARNING

• 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.

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 that your vehicle 

must be disposed of, the hybrid battery 

must be disposed of by your Lexus 

dealer or a qualified service shop. If 

the hybrid battery is not disposed of 

properly, it may cause electric shock 

that can result in death or serious 

injury.

: These lights come on when the power 

switch is turned to ON to indicate that a 
system check is being performed. They 
will turn off after the hybrid system is 
started, or after a few seconds. There 
may be a malfunction in a system if the 
lights do not come on, or turn off. Have 
the vehicle inspected by your Lexus 
dealer.

WARNING

If a safety system warning light does 

not come on

Should a safety system light such as the 

ABS and SRS warning lights not come on 

when you start the hybrid system, this 

could mean that these systems are not 

available to help protect you in an acci-

dent, which could result in death or seri-

ous injury. Have the vehicle inspected by 

your Lexus dealer immediately if this 

occurs.
