*1: To improve fuel efficiency and reduce noise, shift the shift lever to D for normal
driving.
You can choose gear range suitable for
your driving situation by operating the
paddle shift switches.
*2: By selecting shift ra nges using S mode,
you can control accelerating force and
engine braking force.
■S mode
●When the shift range is 4 or lower, hold-
ing the shift lever towa rd “+” sets the shift
range to 6.
●Automatically selects a higher shift range
before the engine speed becomes too
high.
■When driving with dynamic radar cruise
control with full-speed range activated
Even when performing the following
actions with the intent of enabling engine
braking, engine braking will not activate
because dynamic radar cruise control with
full-speed range will not be canceled.
●While driving in S mode, downshifting to
5 or 4. ( P.176)
●When switching the driving mode to
Sport mode while driving in D position.
( P.248)
■Restraining sudden start (Drive-Start
Control)
When the following unusual operation is
performed, the hybrid system output may
be restrained.
●When the shift lever is shifted from R to D,
D to R, N to R, P to D, or P to R (D
includes S) with the accelerator pedal
depressed, a warning message appears
on the multi-information display. If a
warning message is shown on the multi-
information display, read the message
and follow the instructions.

The selected shift range, from 1 to 6, will be
displayed on the multi-information display.
The initial shift range is 4 when the “-” pad-
dle shift switch is operated.
To return to normal D position driving, the
“+” paddle shift switch must be held down
for a period of time.
■Shift ranges and their functions
 You can choose from 6 levels of
engine braking force.
 A lower shift range will provide
greater engine braking force than a
higher shift range, and the engine
revolutions will also increase.
■Automatic deactivation of shift range
selection in the D position
Shift range selection in the D position will be deactivated in the following situations:
●When the vehicle comes to a stop
●If the accelerator pe
dal is depressed for
more than a certai n period of time
●When the shift lever is shifted to a posi-
tion other than D
To enter S mode, shift the shift lever to
S. Shift ranges can be selected by
operating the shift lever or paddle shift
switches, allowing you to drive in the
shift range of your choice. The shift
range can be selected by operating the

celed depending on the driving conditions,
such as when the tires slip due to sudden
acceleration.ASC (Active Sound Con-
trol)*
The ASC system is an electronic
sound system that generates
engine sound, conveying the
kinetic situations of the vehicle’s
acceleration and deceleration to
the driver throug h the speakers
inside the instrument panel.
The vehicle’s response to the
driver’s accelerati on behavior and
shift operations are also conveyed
in sound.
When Sport mode is selected, the
sound conveyed to the driver will be

■Sensor detectio n information
●The sensor’s detection areas are limited
to the areas around the vehicle’s bumper.
●Certain vehicle conditions and the sur-
rounding environment may affect the
ability of a sensor to correctly detect an
obstacle. Particular instances where this
may occur are listed below.
• There is dirt, snow or ice on the sensor. (Wiping the sensors will resolve this
problem.)
• The sensor is frozen. (Thawing the area will resolve this problem.)
In especially cold weather, if a sensor is
frozen the screen may show an abnormal
display, or obstacles may not be
detected.
• The sensor is covered in any way.
• The vehicle is leaning considerably to one side.
• On an extremely bumpy road, on an incline, on gravel, or on grass.
• The vicinity of the vehicle is noisy due to vehicle horns, motorcycle engines, air
brakes of large vehicles, or other loud
noises producing ultrasonic waves.
• There is another vehicle equipped with parking assist sensors in the vicinity.
• The sensor is coated with a sheet of spray or heavy rain.
• The vehicle is equipped with a fender
pole or wireless antenna.
• Towing eyelets are installed.
• The bumper or sensor receives a strong impact.
• A backlit license plate, license plate holder, etc., are installed.
• The vehicle is approaching a tall or curved curb.
• In harsh sunlight or intense cold weather.
• The area directly under the bumpers is
not detected.
• If obstacles draw too close to the sensor.
• A non-genuine Lexus suspension (low- ered suspension etc.) is installed.
• People may not be detected if they are wearing certain types of clothing.
In addition to the examples above, there are
instances in which, because of their shape,
signs and other objects may be judged by a
sensor to be closer than they are.
●The shape of the obstacle may prevent a sensor from detecting it. Pay particular
attention to the following obstacles:
• Wires, fences, ropes, etc.
• Cotton, snow and other materials that
absorb sound waves
• Sharply-angled objects
• Low obstacles
• Tall obstacles with upper sections pro- jecting outwards in the direction of your
vehicle
●The following situations may occur
during use.
• Depending on the shape of the obstacle and other factors, the detection distance
may shorten, or detection may be impos-
sible.
• Obstacles may not be detected if they
are too close to the sensor.
• There will be a short delay between obstacle detection and display. Even at
slow speeds, there is a possibility that the
obstacle will come within the sensor’s
detection areas befo re the display is
shown and the buzzer sounds.
• Thin posts or object s lower than the sen-
sor may not be detected when
approached, even if they have been
detected once.
• It might be difficult to hear beeps due to
the volume of audio system or air flow
noise of the air conditioning system.
■Customization
Some functions can be customized.
(Customizable features: P.421)

mation display. ( P.209)
■When the message is displayed on the
multi-information display showing that
TRAC has been disabled even if has
not been pressed
TRAC cannot be operated. Contact your
Lexus dealer.
■Sounds and vibrations caused by the
ABS, brake assist, VSC, Trailer Sway
Control, TRAC and hi ll-start assist con-
trol systems
●A sound may be heard from the engine
compartment when the brake pedal is
depressed repeatedly, when the hybrid
system is started or just after the vehicle
begins to move. This sound does not indi- cate that a malfunction has occurred in
any of these systems.
●Any of the following conditions may
occur when the above systems are oper-
ating.
None of these indicates that a malfunc-
tion has occurred.
• Vibrations may be felt through the vehicle
body and steering.
• A motor sound may be heard also after the vehicle comes to a stop.
■ECB operating sound
ECB operating sound may be heard in the
following cases, but it does not indicate that
a malfunction has occurred.
●Operating sound heard from the engine
compartment when the brake pedal is
operated.
●Motor sound of the brake system heard
from the front part of the vehicle when
the driver’s door is opened.
●Operating sound heard from the engine
compartment when one or two minutes
passed after the stop of the hybrid sys-
tem.
■EPS operation sound
When the steering wheel is operated, a
motor sound (whirring sound) may be
heard. This does not indicate a malfunction.
■Reduced effectiveness of the EPS sys-
tem
The effectiveness of the EPS system is
reduced to prevent the system from over-
heating when there is frequent steering
input over an extended period of time. The
steering wheel may feel heavy as a result.
Should this occur, re frain from excessive
steering input or stop the vehicle and turn
the hybrid system off. The EPS system
should return to normal within 10 minutes.
■Automatic reactivation of TRAC, Trailer
Sway Control and VSC systems
After turning the TARC, Trailer Sway Con-
trol and VSC systems off, the systems will
be automatically re-enabled in the following

4-6.Driving tips
When using Eco mode, the torque cor-
responding to the accelerator pedal
depression amount can be generated
more smoothly than it is in normal con-
ditions. In addition, the operation of the
air conditioning system (heating/cool-
ing) will be minimized, improving the
fuel economy. (P.248)
The Eco-friendly driving is possible by
keeping the indicator needle of Hybrid
System Indicator within Eco area.
(  P.82)
Shift the shift lever to D when stopped
at a traffic light, or driving in heavy traf-
fic, etc. Shift the shift lever to P when
parking. When using the N, there is no
positive effect on fuel consumption. In
the N, the gasoline engine operates
but electricity cannot be generated.
Also, when using the air conditioning
system, etc., the hybrid battery (trac-
tion battery) power is consumed. 
Drive your vehicle smoothly. Avoid
abrupt acceleration and decelera-
tion. Gradual acceleration and
deceleration will make more effec-
tive use of the electric motor (trac-
tion motor) without having to use
gasoline engine power.
 Avoid repeated acceleration.
Repeated acceleration consumes
hybrid battery (traction battery)
power, resulting in poor fuel con-
sumption. Battery power can be
restored by driving with the acceler-
ator pedal slightly released.
Make sure to operate the brakes gently
and in a timely manner. A greater
amount of electrical energy can be
regenerated when slowing down.
Repeated acceleration and decelera-
tion, as well as long waits at traffic
lights, will lead to bad fuel economy.
Check traffic reports before leaving
and avoid delays as much as possible.
When driving in a traffic jam, gently
release the brake pedal to allow the
vehicle to move forward slightly while
avoiding overuse of the accelerator
pedal. Doing so can help control
excessive gasoline consumption.
