■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.361) 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 2.4gal. [9.0 L, 2.0 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
vehicles incorporate electromagnetic
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 th e warning labels attached to the vehi-
cle.

■If a warning message is displayed on the multi-information display
A system may be temporarily unavailable or there may be a malfunction in the system.
●In the following situations, perform the action s specified in the table. When the normal
operating conditions are detected, the me ssage will disappear and the system will
become operational.
If the message does not disappear, contact your Lexus dealer.
SituationActions
When the area around a sensor is covered
with dirt, moisture (f ogged up, covered with
condensation, ice, etc. ), or other foreign
matterTo clean the part of the windshield in front of
the front camera, use the windshield wipers
or the windshield defogger of the air condi-
tioning system ( P.254).
When the temperature around the front
camera is outside of th e operational range,
such as when the vehicle is in the sun or in an
extremely cold environment
If the front camera is hot, such as after the
vehicle had been parked in the sun, use the
air conditioning system to decrease the tem-
perature around the front camera.
If a sunshade was used when the vehicle was
parked, depending on it s type, the sunlight
reflected from the surface of the sunshade
may cause the temperature of the front cam-
era to become excessively high.
If the front camera is cold, such after the
vehicle is parked in an extremely cold envi-
ronment, use the air conditioning system to
increase the temperature around the front
camera.
The area in front of the front camera is
obstructed, such as when the hood is open
or a sticker is attached to the part of the
windshield in front of the front camera.
Close the hood, remove the sticker, etc. to
clear the obstruction.

2024-5. Using the driving support systems
object may increase in the following situ-
ations:
• When the sensor is misaligned due to a strong impact to the sensor or its sur-
rounding area
• When the distance between your vehicle and a guardrail, wall, etc. that enters the
detection area is short
• When driving up an d down consecutive
steep inclines, such as hills, dips in the
road, etc.
• When vehicle lanes are narrow, or when driving on the edge of a lane, and a vehi-
cle traveling in a lane other than the adja-
cent lanes enters the detection area
• When driving on roads with sharp bends,
consecutive curves, or uneven surfaces
• When the tires are slipping or spinning
• When the distance between your vehicle and a following vehicle is short
• When an accessory (such as a bicycle carrier) or towing eyel et is installed to the
rear of the vehicle
1 Normal mode
Provides an optimal ba lance of fuel econ-
omy, quietness, and dynamic performance.
Suitable for city driving.
Press the switch to change the normal
mode when not in normal mode.
2 Eco drive mode
Helps the driver acce lerate in an eco-
friendly manner and improve fuel economy
through moderate thro ttle characteristics
and by controlling the operation of the air
conditioning system (heating/cooling).
When not in Eco drive mode, if the Driving
Mode Select switch is turned toward you,
the “Eco” indicator comes on.
3 Sport mode
Controls the hybrid system to provide
quick, powerful acceleration. This mode is
suitable for when agile driving response is
desired, such as when driving on roads
with many curves.

When not in SPORT mode, if the Driving
Mode Select switch is turned away from
you, the “Sport” indicator comes on.
■Operation of the air conditioning sys-
tem in Eco drive mode
Eco drive mode contro ls the heating/cool-
ing operations and fan speed of the air con-
ditioning system to enhance fuel efficiency.
To improve air condit ioning performance,
perform the following operations:
●Turn off eco air conditioning mode
(  P.257)
●Adjust the fan speed ( P.256)
●Turn off Eco drive mode ( P.202)
■Auto Glide Control
●While driving in Eco drive mode with D
position, selected, releasing the accelera-
tor pedal will activate Auto Glide Control
under certain conditions. (Auto Glide
Control may activate before the acceler-
ator pedal is fully released.)
When Auto Glide Control operates, the
electric motor (traction motor) will be
controlled, reducing the deceleration
force and allowing the vehicle to coast,
enhancing fuel economy.
When Auto Glide Control operates, the
AGC indicator light will illuminate.
●Auto Glide Control may not operate in
the following situations:
• When not in Eco drive mode
• When the brake pedal is depressed
• When a shift position other than D is selected
• When the vehicle speed is approximately 10 mph (15 km/h) or lower
• When the vehicle is accelerating on a
downward slope
• When the PCS (Pre-Collision System) is operating
• When the dynamic radar cruise control with full-speed range is operating
• When the PKSB (Parking Support Brake)
system is operating
• When the TRAC or VSC system is oper- ating
• When the TRAC or VSC system is dis-
abled by pressing the switch
■Automatic deactivation of sport mode
If the power switch is turned off after driving
in sport mode, the drive mode will be
changed to normal mode.
■Driving mode pop-up display (12.3-inch
display model)
When the driving mode is changed, the
selected driving mode will be temporarily
displayed on the side display. ( P.249)

■The system can be operated when
●The power switch is in ON mode.
●Intuitive parking assist function is on.
●The vehicle speed is less than about 6
mph (10 km/h).
●A shift lever is shifted to a position other
than P.
■Setting the buzzer volume
The buzzer volume can be adjusted on the
multi-information display. ( P.204)
■If “Parking Assist Unavailable Clean
Parking Assist Sensor” is displayed on
the multi-information display
A sensor may be covered with ice, snow,
dirt, etc. Remove the ice, snow, dirt, etc.,
from the sensor to return the system to nor-
mal.
Also, due to ice forming on a sensor at low
temperatures, a warning message may be
displayed or the sensor may not be able to
detect an object. Once the ice melts, the
system will return to normal.
■Sensor detection information
●The sensor’s detectio n areas are limited
to the areas around the vehicle’s front and
rear bumpers.
●The following situations may occur
during use.
• Depending on the shape of the object
and other factors, the detection distance
may shorten, or detection may be impos-
sible.
• There will be a short delay between object detection and di splay. Even at low
speeds, there is a possibility that the
object will come within the sensor’s
detection areas befo re the display is
shown and the warning beep sounds.
• It might be difficult to hear the buzzer due to the volume of the audio system or air
flow noise of the air conditioning system.
■Conditions under wh ich the function
may not function correctly
Certain vehicle conditions and the sur-
rounding environment may affect the ability
of a sensor to correctly detect objects. Par-
ticular instances where this may occur are
listed below.
●There is dirt, snow or ice on a sensor.
(Cleaning the sensors will resolve this
problem.)
●A sensor is frozen. (Thawing the area will
resolve this problem.)
In especially cold weather, if a sensor is
WARNING
■When using intuitive parking assist
In the following situations, the system
may not function correctly due to a sen-
sor malfunction, etc. Have the vehicle
checked by your Lexus dealer.
●The intuitive parking assist operation
display flashes or shows continuously,
and a buzzer sounds when no objects
are detected.
●If the area around a sensor collides
with something, or is subjected to
strong impact.
●If the bumper or grille collides with
something.
●If the display flashes or is displayed
continuously and a buzzer does not
sound, except when the mute function
has been turned on.
●If a display error occurs, first check the
sensor.
If the error occurs even when there is
no ice, snow or mud on the sensor, it is
likely that the sensor is malfunctioning.
■Notes when washing the vehicle
Do not apply intensive bursts of water or
steam to the sensor area.
Doing so may result in the sensor mal-
functioning.
●When using a high pressure washer to
wash the vehicle, do not spray the sen-
sors directly, as doing so may cause a
sensor to malfunction.
●When using steam to clean the vehicle,
do not direct steam too close to the
sensors as doing so may cause a sen-
sor to malfunction.

• Pedestrians who are bending forward or squatting
• Pedestrians who are lying down
• Pedestrians who are running
• Pedestrians who suddenly enter the detection area
• People riding a bicycle, skateboard, or
other light vehicle
• Pedestrians wearing oversized clothing such as a rain coat, long skirt, etc., making
their silhouette obscure
• Pedestrians whose body is partially hid- den by an object, such as a cart or
umbrella
• Pedestrians which are obscured by dark- ness, such as at night
●In some situations, such as the following,
pedestrians may not be detected by the
rear camera detection function, prevent-
ing the function from operating properly:
• When backing up in inclement weather (rain, snow, fog, etc.)
• When the rear camera is obscured (dirt, snow, ice, etc. are attached) or scratched
• When a very bright light, such as the sun,
or the headlights of another vehicle,
shines directly into the rear camera
• When backing up in a place where the
surrounding brightness changes sud-
denly, such as at the entrance or exit of a
garage or underground parking lot
• When backing up in a dim environment such as during dusk or in an underground
parking lot
●Even though there are no pedestrians in
the detection area, some objects, such as
the following, may be detected, possibly
causing the rear camera detection func-
tion to operate.
• Three dimensional objects, such as a pole, traffic cone, fence, or parked vehi-
cle
• Moving objects, such as a car or motor- cycle
• Objects moving toward your vehicle
when backing up, such as flags or pud-
dles (or airborne matter, such as smoke,
steam, rain, or snow)
• Cobblestone or gravel roads, tram rails, road repairs, white lines, pedestrian
crossings or fallen leaves on the road
• Metal covers (gratings), such as those used for drainage ditches • Objects reflected in a puddle or on a wet
road surface
• The roadside or bumps on the road
•Shadows on the road
●In some situations, such as the following,
the rear camera detection function may
operate even though there are no pedes-
trians in the detection area.
• When backing up toward the roadside or
a bump on the road
• If the vehicle is signif icantly tilted, such as
when carrying a heavy load
• When backing up toward an incline/decline
• If the suspension has been modified or
tires of a size othe r than specified are
installed
• If the rear of the vehicle is raised or low-
ered due to the carried load
• If an electronic component, such as a backlit license plate is installed near the
rear camera
• If a bumper protector, such as an addi- tional trim strip, is installed to the rear
bumper
• If the orientation of the rear camera has been changed due to a collision or other
impact, or removal and installation
• If a towing eyelet is in stalled to the rear of
the vehicle
• When water is flowing over the rear cam-
era lens
• When the rear camera is obscured (dirt,
snow, ice, etc. are at tached) or scratched
• If there is a flashing light in the detection area, such as the emergency flashers of
another vehicle
●Situations in which the rear camera
detection function may be difficult to
notice
• The buzzer may be difficult to hear if the surrounding area is noisy, the volume of
the audio system volume is high, the air
conditioning system is being used, etc.
• If the temperature in the cabin is
extremely high or low, the Center Display
may not operate correctly.

2404-6. Driving tips
4-6.Driving tips
When using Eco drive mode, the
torque corresponding to the accelera-
tor pedal depression amount can be
generated more smoothly than it is in
normal conditions. In addition, the
operation of the air conditioning sys-
tem (heating/cooling) will be mini-
mized, improving the fuel economy.
( P.202)
The Eco-friendly driving is possible by
keeping the indicate of Hybrid System
Indicator within Eco area. ( P.71)
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.
