When installing in the rear center
seat
There are no LATCH anchors behind
the rear center seat. However, the
inboard LATCH anchors of the out-
board seats, which are 18.1 in. (460
mm) apart, can be used if the child
restraint system manufacturer’s
instructions permit use of those
anchors with the anchor spacing
stated.
Child restraint systems with rigid lower
attachments cannot be installed in the
center seat. This type of child restraint
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.

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.

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
safety standards previously set by the
following U.S. and international stan-
dards bodies.
ANSI (American National Stan-
dards Institute) C95.1 [1992]
NCRP (National Council on Radia-
tion Protection and Measurement)
Report 86 [1986]
ICNIRP (International Commission
on Non-Ionizing Radiation Protec-
tion) [1996]
Those standards were based on com-
prehensive and periodic evaluations of
the relevant scientific literature. Over

Hybrid system features
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 efficiency and
reducing exhaust emissions.

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 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).
●
The accelerator pedal is released while
driving with the shift lever in D or S.
●
The brake pedal is depressed while driv-
ing with the shift lever in D or S.
■
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
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
■
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 vehicle
There may be no engine sound or vibration
even though the vehicle is able to move with
the “READY” indicator is illuminated. For
safety, apply the parking brake and make
sure to 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:

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.413) 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 2.9 gal. [11.0 L, 2.4 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.)
Hybrid system precautions
Take care when handling the hybrid system, as it is a high voltage system (about
650 V at maximum) as well as contains parts that become extremely hot when
the hybrid system is operating. Obey the warning labels attached to the vehi-
cle.

Electromagnetic waves
●
High voltage parts and cables on hybrid
vehicles incorporate electromagnetic
shielding, and therefore emit approxi-
mately the same amount of electromag-
netic waves as conventional gasoline
powered vehicles or home electronic
appliances.
●
Your vehicle may cause sound interfer-
ence in some third party-produced radio
parts.
■
Hybrid battery (traction battery)
The hybrid battery (traction battery) has a
limited service life. The lifespan of the
hybrid battery (traction battery) can
change in accordance with driving style and
driving conditions.
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:
●
Pull your vehicle off the road, shift the
shift lever to P, apply the parking brake,
and turn the hybrid system off.
●
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 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 danger-
ous.

For safety and security
The air intake/discharge vents for the
hybrid battery (traction battery) are
located under the rear seats and in lug-
gage compartment respectively. If the
air intake vents are blocked, it could
lead to a reduction in hybrid battery
(traction battery) output.
WARNING
●
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. (
●
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.
• 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.
