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
transmitter 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)

Those standards were based on com-
prehensive and periodic evaluations of
the relevant scientific literature. Over
120 scientists, engineers, and physi-
cians from universities, and govern-
ment health agencies and industries
reviewed the available body of
research to develop the ANSI Stan-
dard (C95.1).
The design of Safety Connect com-
plies with the FCC guidelines in addi-
tion to those standards.

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 effi-
ciency and reducing exhaust emissions.

charged.
*
: When the hybrid battery (traction bat-
tery) requires charging or the engine is
warming up, etc., the gasoline engine will
not automatically stop. (
P.61)
■
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 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
gasoline engine may also not stop auto-
matically 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 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 dis-
charged and you are unable to start the
hybrid system, contact your Lexus dealer.
■
Charging the 12-volt battery
P.400
■
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
battery (traction battery). If this continues
for a few days, contact your Lexus dealer.

Sounds and vibrations specific to a
Hybrid Electric 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:
●
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), behind the rear
seats, when the hybrid system is started
or stopped.
●
Sounds from the hybrid system may be
heard when the back door is open.
●
Sounds may be heard from the hybrid
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 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 vent under the right side of
the rear seat.
■
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
Settings (e.g. on/off operation of the EV
indicator) can be changed.
(Customizable features:
P.427)
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).
■
Acoustic Vehicle Alerting System
In the following cases, the Acoustic Vehicle
Alerting System may be difficult for sur-
rounding people to hear.
●
In very noisy areas
●
In the wind or the rain
Also, as the Acoustic Vehicle Alerting Sys-
tem 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.
*
: This function can only be used in the
mainland U.S.A. It cannot be used in
other states and territories, including
Alaska and Hawaii.
This system operates based on the
driving situation and traffic information
to enhance fuel economy.

control
The following types of control are per-
formed based on data such as road
and traffic information during route
guidance by the navigation system to
help ensure that the vehicle efficiently
uses electricity.
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 traveling
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.382) 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 1.8 gal. [7.0 L, 1.5 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)
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 underneath the
rear seats. 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
electric 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.
66
1-4. Hybrid system
There is an air intake vent under the
right side of the rear seat with the pur-
pose of cooling the hybrid battery
(traction battery).
If the vent is blocked, it may interfere
with the cooling of the hybrid battery
(traction battery).
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 be
reduced.
WARNING
●
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 front wheels (2WD models) or
four wheels (AWD models) 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.373)
●
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 Lexus 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 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
Electric Vehicle. If the hybrid battery is
used outside of your vehicle or modi-
fied in any way, accidents such as elec-
tric shock, heat generation, smoke
generation, an explosion and electro-
lyte 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 prop-
erly, it may cause electric shock that
can result in death or serious injury.
NOTICE
■
Hybrid battery (traction battery)
Do not carry large amounts of water
such as water cooler bottles in the vehi-
cle. If water spills onto the hybrid battery
(traction battery), the battery may be
damaged. Have the vehicle inspected by
your Lexus dealer.
