LEXUS NX300h Owners Manu-
al_USA_OM78212U 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-
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.

Lexus does not recommend towing a WARNING●
Secure all items in the occupant com-
partment.■
When using a roof luggage carrier
(vehicles with roof rails)
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.400)●
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 result 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 sp eeds, stop the vehi-
cle now and then during the trip to
make sure the cargo remains in its
place.
●
Do not exceed 176.3 lb. (80 kg) cargo
weight on the roof luggage carrier.
NOTICE
■
When loading cargo (vehicles with
moon roof)
Do not set luggage on the moon roof.
Failure to observe so may lead to cause
damage.

Driving trailer with your vehicle. Your vehicle is
not designed for trailer towing.
Cargo capacity
Total load capacity (vehicle capac-
ity weight) ( → P.400)
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 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 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.WARNING■
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.
