For safety and security
The pretensioners help the seat belts to
quickly restrain the occupants by
retracting the seat belts when the vehi-
cle is subjected to certain types of
severe frontal or side collision or a
vehicle rollover.
The pretensioners do not activate in the
event of a minor frontal impact, a minor
side impact or a rear impact.
■Replacing the belt after the
pretensioner has been activated
If the vehicle is involv ed in multiple colli-
sions, the pretensioner will activate for the
first collision, but will not activate for the
second or subsequent collisions.
Seat belt pretensioners (front
seats and outboard second-row
seats)
WARNING
■Seat belt pretensioners
Observe the following precautions to
reduce the risk of injury in the event of
sudden braking, sudden swerving or an
accident.
Failure to do so may cause death or seri-
ous injury.
●Do not place anything, such as a cush-
ion, on the front passenger’s seat.
Doing so will disperse the passenger’s
weight, which prevents the sensor
from detecting the passenger’s weight
properly. As a result, the seat belt
pretensioner for the front passenger’s
seat may not activate in the event of a
collision.
●If the pretensioner has activated, the
SRS warning light will come on. In that
case, the seat belt cannot be used
again and must be replaced at your
Lexus dealer.

381-1. For safe use
WARNING
●Do not attach anything to areas such
as a door, windshield, side windows,
front or rear pillar, roof side rail and
assist grip.
●Do not hang coat hangers or other
hard objects on the coat hooks. All of
these items could become projectiles
and may cause death or serious injury,
should the SRS curtain shield airbags
deploy.
●If a vinyl cover is put on the area where
the SRS knee airbag will deploy, be
sure to remove it.
●Do not use seat accessories which
cover the parts where the SRS side
airbags and SRS seat cushion airbag
inflate as they may interfere with infla-
tion of the SRS airbags. Such accesso-
ries may prevent the side airbags and
SRS seat cushion airbag from activat-
ing correctly, disable the system or
cause the side airbags and SRS seat
cushion airbag to inflate accidentally,
resulting in death or serious injury.
●Do not strike or apply significant levels
of force to the area of the SRS airbag
components or the front doors. Doing
so can cause the SRS airbags to mal-
function.
●Do not touch any of the component
parts immediately after the SRS
airbags have deployed (inflated) as
they may be hot.
●If breathing becomes difficult after the
SRS airbags have deployed, open a
door or window to allow fresh air in, or
leave the vehicle if it is safe to do so.
Wash off any residue as soon as possi-
ble to prevent skin irritation.
●If the areas where the SRS airbags are
stored, such as the steering wheel pad
and front and rear pillar garnishes, are
damaged or cracked, have them
replaced by your Lexus dealer.
●Do not place anything, such as a cush-
ion, on the front passenger’s seat.
Doing so will disperse the passenger’s
weight, which prevents the sensor
from detecting the passenger’s weight
properly. As a result, the SRS front
airbags for the front passenger may
not deploy in the event of a collision.
■Modification and disposal of SRS
airbag system components
Do not dispose of your vehicle or per-
form any of the following modifications
without consulting your Lexus dealer.
The SRS airbags may malfunction or
deploy (inflate) accidentally, causing
death or serious injury.
●Installation, remova l, disassembly and
repair of the SRS airbags
●Repairs, modifications, removal or
replacement of the steering wheel,
instrument panel, dashboard, seats or
seat upholstery, front, side and rear pil-
lars, roof side rails, front door panels,
front door trims or front door speakers
●Modifications to the front door panel
(such as making a hole in it)
●Repairs or modifications of the front
fender, front bumper, or side of the
occupant compartment
●Installation of a grille guard (bull bars,
kangaroo bar, etc. ), snow plows,
winches or roof luggage carrier
●Modifications to the vehicle’s suspen-
sion system

For safety and security
WARNING
●Do not put weight on the front passen-
ger seat by putting your hands or feet
on the front passenger seat seatback
from the rear passenger seat.
●Do not let a rear passenger lift the
front passenger seat with their feet or
press on the seatback with their legs.
●Do not put objects under the front pas-
senger seat.
●Do not recline the front passenger
seatback so far that it touches a rear
seat. This may cause the “AIR BAG
OFF” indicator light to be illuminated,
which indicates that the SRS airbags
for the front passenger will not activate
in the event of a seve re accident. If the
seatback touches the rear seat, return
the seatback to a position where it
does not touch the rear seat. Keep the
front passenger seatback as upright as
possible when the vehicle is moving.
Reclining the seatback excessively
may lessen the effectiveness of the
seat belt system.
●If an adult sits in the front passenger
seat, the “AIR BAG ON” indicator light
is illuminated. If the “AIR BAG OFF”
indicator is illuminated, ask the passen-
ger to sit up straight, well back in the
seat, feet on the floor, and with the seat
belt worn correctly. If the “AIR BAG
OFF” indicator still remains illumi-
nated, either ask the passenger to
move to the rear seat, or if that is not
possible, move the front passenger
seat fully rearward.
●When it is unavoidable to install a for-
ward-facing child restraint system on
the front passenger seat, install the
child restraint system on the front pas-
senger seat in the proper order.
(
P.46)
●Do not modify or remove the front
seats.
●Do not kick the front passenger seat or
subject it to severe impact. Otherwise,
the SRS warning light may come on to
indicate a malfunction of the front pas-
senger occupant cla ssification system.
In this case, contact your Lexus dealer
immediately.
●Child restraint system s installed on the
rear seat should not contact the front
seatbacks.
●Do not use a seat accessory, such as a
cushion and seat cover, that covers the
seat cushion surface.
●Do not modify or replace the uphol-
stery of the front seat.

461-2. Child safety
ings, as well as the laws and regula-
tions for child restraint systems.
 Use a child restraint system until the
child becomes large enough to
properly wear the vehicle’s seat belt.
 Choose a child restraint system that
suits your vehicle and is appropriate
to the age and size of the child.
■Types of child restraint system installation methods
Confirm with the operation manual enclosed with the child restraint system about
the installation of the child restraint system.
WARNING
■When a child is riding
Observe the following precautions.
Failure to do so may result in death or
serious injury.
●For effective protecti on in automobile
accidents and sudden stops, a child
must be properly restrained, using a
seat belt or child restraint system
which is correctly inst alled. For installa-
tion details, refer to the operation man-
ual enclosed with the child restraint
system. General insta llation instruction
is provided in this manual.
●Lexus strongly urges the use of a
proper child restraint system that con-
forms to the weight and size of the
child, installed on the second-row seat.
According to accident statistics, the
child is safer when properly restrained
in the second-row seat than in the front
seat.
●Holding a child in your or someone
else’s arms is not a substitute for a child
restraint system. In an accident, the
child can be crushe d against the wind-
shield or between the holder and the
interior of the vehicle.
■Handling the child restraint system
If the child re straint system is not prop-
erly fixed in place, th e child or other pas-
sengers may be seriously injured or even
killed in the event of sudden braking, sud-
den swerving, or an accident.
●If the vehicle were to receive a strong
impact from an accident, etc., it is pos-
sible that the child restraint system has
damage that is not readily visible. In
such cases, do not reuse the restraint
system.
●Make sure you have complied with all
installation instruct ions provided with
the child restraint system manufac-
turer and that the system is properly
secured.
●Keep the child rest raint system prop-
erly secured on the seat even if it is not
in use. Do not store the child restraint
system unsecured in the passenger
compartment.
●If it is necessary to detach the child
restraint system, remove it from the
vehicle or store it securely in the lug-
gage compartment.

Driving
Cargo capacity depends on the total
weight of the occupants.
(Cargo capacity) = (Total load capac-
ity) — (Total weight of occupants)
Steps for Determining Correct Load
Limit —
(1) Locate the statement “The com-
bined weight of occupants and cargo
should never exceed XXX kg or XXX
lbs.” on your vehicle’s placard.
(2) Determine the combined weight of
the driver and passengers that will be
riding in your vehicle.
(3) Subtract the combined weight of
the driver and passengers from XXX
kg or XXX lbs.
(4) The resulting figure equals the
available amount of cargo and luggage
load capacity.
For example, if the “XXX” amount
equals 1400 lbs. and there will be five
150 lb passengers in your vehicle, the
amount of available cargo and luggage
load capacity is 650 lbs. (1400 − 750
(5  150) = 650 lbs.)
(5) Determine the combined weight of
luggage and cargo being loaded on
the vehicle. That weight may not safely
exceed the available cargo and lug-
NOTICE
■If you get a flat tire while driving
A flat or damaged tire may cause the fol-
lowing situations. Hold the steering
wheel firmly and gradually depress the
brake pedal to slow down the vehicle.
●It may be difficult to control your vehi-
cle.
●The vehicle will make abnormal
sounds or vibrations.
●The vehicle will lean abnormally.
Information on what to do in case of a flat
tire (
P.424)
■When encountering flooded roads
Do not drive on a road that has flooded
after heavy rain etc. Doing so may cause
the following serious damage to the vehi-
cle:
●Engine stalling
●Short in electrical components
●Engine damage caused by water
immersion
In the event that you drive on a flooded
road and the vehicle is flooded, be sure
to have your Lexus dealer check the fol-
lowing:
●Brake function
●Changes in quantity and quality of oil
and fluid used for the engine, hybrid
transmission, rear differential, etc.
●Lubricant condition for bearings and
suspension joints (where possible),
and the function of all joints, bearings,
etc.
Cargo and luggage
Take notice of the following infor-
mation about storage precautions,
cargo capacity and load.
Capacity and distribution

1684-1. Before driving
gage load capacity calculated in Step
4.
(6) If your vehicle will be towing a
trailer, load from your trailer will be
transferred to your vehicle. Consult
this manual to determine how this
reduces the available cargo and lug-
gage load capacity of your vehicle.
( P.170)
Vehicles without towing package: Lexus
does not recommend towing a trailer with
your vehicle. Your vehicle is not designed
for trailer towing.
Cargo capacity
Total load capacity (vehicle capac-
ity weight) ( P.452)
When 2 people with the combined
weight of A lb. (kg) are riding in your
vehicle, which has a total load capacity
(vehicle capacity weight) of B lb. (kg),
the available amount of cargo and lug-
gage load capacity will be C lb. (kg) as
follows:
B
*2 lb. (kg) - A*1 lb. (kg) = C*3 lb. (kg)
*1: A =Weight of people
*2: B =Total load capacity
*3:C =Available carg o 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 occupant s 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.

Failure to do so may prevent the pedals
from being depressed properly, may
block the driver’s visi on, or may result in
items hitting the driver or passengers,
possibly causing an accident.
●Stow cargo and luggage in the lug-
gage compartment whenever possi-
ble.

WARNING
●Do not stack cargo and luggage in the
luggage compartment higher than the
seatbacks.
●When you fold down the rear seats,
long items should not be placed
directly behind the front seats.
●Never allow anyone to ride in the lug-
gage compartment. It is not designed
for passengers. They should ride in
their seats with their seat belts prop-
erly fastened.
●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 luggage cover
• On the instrument panel
•On the dashboard
●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.
■Roof luggage carrier precautions
Observe the following precautions:
●Place the cargo so that its weight is dis-
tributed evenly between the front and
rear axles.
●If loading long or wide cargo, never
exceed the vehicle overall length or
width. (
P.452)
●Before driving, make sure the cargo is
securely fastened on the roof luggage
carrier.
●Loading cargo on the roof luggage
carrier will make the center of gravity
of the vehicle higher. Avoid high
speeds, sudden starts, sharp turns,
sudden braking or abrupt maneuvers,
otherwise it may resu lt in loss of con-
trol or vehicle rollover due to failure to
operate this vehicle correctly and
result in death or serious injury.
●If driving for a long distance, on rough
roads, or at high speeds, stop the vehi-
cle now and then during the trip to
make sure the cargo remains in its
place.
●Do not exceed 165 lb. (75 kg) cargo
weight on the roof luggage carrier.
