*1: The system judges a person of adult size as an adult. When a smaller adult sitsin the front passenger seat, the system may recognize him/her as a child
depending on his/her physique and posture.
*2: In the event the front passenger does not wear a seat belt
*3: When a larger child who has outgrown a ch ild restraint system sits in the front
passenger seat, the system may recogn ize him/her as an adult depending on
his/her physique or posture.
*4: Never install a rear-facing child restraint system on the front passenger seat. A forward-facing child restraint system shou ld only be installed on the front pas-
senger seat when it is unavoidable. ( P. 5 5 )
*5: In case the indicator light is not illumi nated, consult this manual on how to
install the child restraint system properly. ( P. 5 9 )
CAUTION
■Front passenger occupant classification system precautions
Observe the following precautions regarding the front passenger occupant classi-
fication system.
Failure to do so may caus e death or serious injury.
●Wear the seat belt properly.
●Make sure the front passenger’s seat belt plate has not been left inserted into the
buckle before someone sits in the front passenger seat.
●Make sure the “AIR BAG OFF” indicator li ght is not illuminated when using the
seat belt extender for the front passen ger seat. If the “AIR BAG OFF” indicator
light is illuminated, disconnect the extender tongue from the seat belt buckle, and
reconnect the seat belt. Reconnect the seat belt extender after making sure the
“AIR BAG ON” indicator light is illuminated. If you use the seat belt extender
while the “AIR BAG OFF” indicator light is illuminated, the SRS airbags for the
passenger may not activate correctly, which could cause death or serious injury
in the event of a collision.
●Do not apply a heavy load to the front passenger seat or equipment (e.g. seat-
back pockets or armrest).
●Do not put weight on the front passenger 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 passenger seat.

CAUTION
■Using the trunk
Observe the following precautions.
Failure to do so may cause parts of the body to be caught, resulting in serious
injury.
●Remove any heavy loads, such as snow and ice, from the trunk lid before opening
it. Failure to do so may cause the trunk lid to fall closed again after it is opened.
●When opening or closing the trunk lid, thoroughly check to make sure the sur-
rounding area is safe.
●If anyone is in the vicinity, make sure they are safe and let them know that the
trunk is about to open or close.
●Use caution when opening or closing the trunk lid in windy weather as it may
move abruptly in strong wind.
●Do not attach any accessories other than genuine Lexus parts to the trunk lid.
Such additional weight on th e trunk lid may cause the lid to fall closed again after
it is opened.
●The trunk lid may fall if it is not opened fully.
It is more difficult to open or close the trunk
lid on an incline than on a level surface, so
beware of the trunk lid unexpectedly open-
ing or closing by itself. Make sure that the
trunk lid is fully open and secure before
using the trunk.
●When closing the trunk lid, take extra care
to prevent your fingers etc. from being
caught.
●When closing the trunk lid, make sure to
press it lightly on it s outer surface. If the
trunk handle is used to fully close the trunk
lid, it may result in hands or arms being
caught.

Cargo and luggage
Cargo capacity depends on the total weight of the occupants.
(Cargo capacity) = (Total load cap acity) — (Total weight of occupants)
Steps for Determining Correct Load Limit —
(1) Locate the statement “The combine d 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 av ailable 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 vehi cle, the amount of available cargo
and luggage load capac ity 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
luggage load capacity calculated in Step 4.
(6) If your vehicle will be towing a trailer, load from your trailer will be trans-
ferred to your vehicle. Consult this manual to determine how this
reduces the available cargo and luggage load capacity of your vehicle.
( P. 1 8 6 )
Lexus does not recommend towing a trailer with your vehicle. Your vehicle is not
designed for trailer towing.

Cargo capacity
Total load capacity
When 2 people with the combined weight of 366 lb. (166 kg) are riding in
your vehicle, which has a total load capacity of 825 lb. (370 kg), the avail-
able amount of cargo and luggage load capacity will be as follows:
825 lb. — 366 lb. = 459 lb. (370 kg —166 kg = 204 kg)
In this condition, if 3 more passengers with the combined weight of 388 lb. (176
kg) get on, the available cargo and luggage load will be reduced as follows:
459 lb. — 388 lb. = 71 lb. (204 kg — 176 kg = 28 kg)
As shown in the example above, if the number of occupants increases, the
cargo and luggage load will be redu ced by an amount that equals the
increased weight due to the addition al 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 luggage on your vehicle.

CAUTION
■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 Remote Touch screen
●Secure all items in the occupant compartment.
■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 dete-
rioration of steering or braking control which may cause death or serious injury.
