1624-1. Before driving
*3: C =Available cargo and luggage load
In this condition, if 3 more passengers with
the combined weight of D lb. (kg) get on,
the available cargo and luggage load will
be reduced E lb. (kg) as follows:
C lb. (kg) - D*4 lb. (kg) = E*5 lb. (kg)
*4: D =Additional weight of people
*5: E =Available cargo and luggage load
As shown in the example above, if the
number of occupants increases, the
cargo and luggage load will be
reduced by an amount that equals the
increased weight due to the additional
occupants. In other words, if an
increase in the number of occupants
causes an excess of the total load
capacity (combined weight of occu-
pants plus cargo and luggage load),
you must reduce the cargo and lug-
gage on your vehicle.
WARNING
■Things that must not be carried in the
trunk
The following things may cause a fire if
loaded in the trunk:
●Receptacles containing gasoline
●Aerosol cans
■Storage precautions
Observe the following precautions.
Failure to do so may prevent the pedals
from being depressed properly, may
block the driver’s vision, or may result in
items hitting the driver or passengers,
possibly causing an accident.
●Stow cargo and luggage in the trunk
whenever possible.
●Do not place cargo or luggage in or on
the following locations.
• At the feet of the driver
• On the front passenger or rear seats (when stacking items)
• On the package tray
• On the instrument panel
• On the dashboard
• In front of the Center Display
●Secure all items in the occupant com-
partment.
■Capacity and distribution
●Do not exceed the maximum axle
weight rating or the total vehicle
weight rating.
●Even if the total load of occupant’s
weight and the cargo load is less than
the total load capacity, do not apply the
load unevenly. Improper loading may
cause deterioration of steering or
braking control which may cause
death or serious injury.

2064-5. Using the driving support systems
bility of a collision with an object, such
as a guardrail, or pedestrian is high,
even though the brakes are applied,
and that the collision may be avoidable
through steering control, the system
will steer the vehicle automatically to
help avoid the collision or help reduce
the impact of the collision.
■Pre-collision seat belts (front seat
only)
If the system determines that the possi-
bility of a frontal collision is high, the
system will retract the seat belts. Addi-
tionally, the system may retract the seat
belts if the brakes are applied suddenly
or control of the vehicle is lost.
■Pre-collision seatbacks (front pas-
senger’s seat / power rear seat [if
equipped])
If the system determines that the possi-
bility of a frontal collision is high, it may
move the seatbacks of the front pas-
senger’s seat and power rear seats to
the upright position automatically, if
reclined.
If a seat is being ad justed, it may not be
moved by the pre-collision seat function.
■Suspension control
When the system determines that the
possibility of a frontal collision is high,
the Adaptive Variable Suspension Sys-
tem ( P.298) will control the damp-
ing force of the shock absorbers to
help maintain an appropriate vehicle
posture.
■Steering control
When the system determines that the
possibility of a frontal collision is high and the driver is op
erating the steering
wheel, the LDH system ( P.298) will
control the turning angle of the front
and rear wheels and effort necessary
to turn the steering wheel to help
enhance steering responsiveness.
WARNING
■Limitations of the pre-collision system
●The driver is solely responsible for safe
driving. Always drive safely, taking
care to observe your surroundings.
Do not use the pre-collision system
instead of normal braking operations
under any circumstances. This system
will not prevent collisions or lessen col-
lision damage or injury in every situa-
tion. Do not overly rely on this system.
Failure to do so may lead to an acci-
dent, resulting in death or serious
injury.
●Although this system is designed to
help avoid a collision or help reduce
the impact of the collision, its effective-
ness may change according to various
conditions, therefore the system may
not always be able to achieve the same
level of performance.
Read the following conditions care-
fully. Do not overly rely on this system
and always drive carefully.
• Conditions under which the system may operate even if there is no possi-
bility of a collision:
P.211
• Conditions under which the system may not operate properly:
P.213
●Do not attempt to test the operation of
the pre-collision system yourself.
Depending on the objects used for
testing (dummies, cardboard objects
imitating detectable objects, etc.), the
system may not operate properly, pos-
sibly leading to an accident.

2164-5. Using the driving support systems
The system can detect the following:
Vehicles
 Bicyclists
 Pedestrians
■Pre-collision warning
When the system determines that the
possibility of a frontal collision is high, a
buzzer will sound and a warning mes- sage will be displayed on the
multi-information display to urge the
driver to take evasive action.
■Pre-collision brake assist
When the system determines that the
possibility of a frontal collision is high,
the system applies greater braking
force in relation to how strongly the
brake pedal is depressed.
■Pre-collision braking
If the system determines that the possi-
bility of a frontal collision is extremely
high, the brakes are automatically
applied to help avoid the collision or
reduce the impact of the collision.
■Pre-collision seatbacks (front pas-
senger’s seat / power rear seat [if
equipped])
If the system determines that the possi-
bility of a frontal collision is high, it may
move the seatbacks of the front pas-
senger’s seat and power rear seats to
the upright position automatically, if
reclined.
If a seat is being adjusted, it may not be
moved by the pre-collis ion seat function.
■Suspension control
When the system determines that the
possibility of a frontal collision is high,
PCS (Pre-Collision System)
(vehicles with Lexus Safety
System + 2.0)
The pre-collision system uses a
radar sensor and front camera to
detect objects ( P.216) in front of
the vehicle. When the system
determines that the possibility of a
frontal collision with an object is
high, a warning operates to urge
the driver to take evasive action
and the potential brake pressure is
increased to help the driver avoid
the collision. If the system deter-
mines that the possibility of a frontal
collision with an object is extremely
high, the brakes are automatically
applied to help avoid the collision or
help reduce the impact of the colli-
sion.
The pre-collision system can be dis-
abled/enabled and the warning tim-
ing can be changed. ( P.218)

ately after the automatic mode switch is
pressed or “AUTO” is selected.
Cool air may blow around the upper body
even when the heater is on due to sunlight.
■Automatic mode for air intake control
In automatic mode, the system detects
exhaust gas and other pollutants and auto-
matically switches between outside air and
recirculated air modes.
When the dehumidification function is off,
and the fan is operating, turning automatic
mode on will activate the dehumidification
function.
This function automatically controls the
air conditioning airflo w so that priority
is given to the front seats. When the
front passenger seat is not occupied,
airflow may switch to only the driver's
seat. Unnecessary air conditioning is
suppressed, contributing to increased
fuel efficiency.
