NX300h_U_OM78007UCargo and luggage Cargo capacity depends on the to tal weight of the occupants.
(Cargo capacity) = (Total load capaci ty) — (Total weight of occupants)
Steps for Determining Correct Load Limit 
(1) Locate the statement “The combined 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 ava ilable 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 luggage
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 avail-
able cargo and luggage load capacity of your vehicle. (  P. 1 8 6 )Vehicles without towing package: Lexus does not recommend towing a trailer with
your vehicle. Your vehicle is not designed for trailer towing.Take notice of the following information about storage precautions, cargo
capacity and load.

Total load capacity (vehicle capacity
weight) (  P. 6 0 8 )
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 avail-
able amount of cargo and luggage 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 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 luggage on
your vehicle. Calculation formula for your vehicle 1

Things that must not be carri ed in the luggage compartment
The following things may cause a fire if loaded in the luggage compartment:●
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 hittin g the driver or passengers, possibly causing
an accident. ●
Stow cargo and luggage in the luggage compartment whenever possible. ●
Do not stack cargo and luggage in the luggage compartment higher than the seat-
backs. ●
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 luggage compartment. It is not designed for pas-
sengers. They should ride in their seats with their se at belts properly 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 th e occupant compartment.■
Capacity and distribution ●
Do not exceed the maximum axle weight ra ting 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. ■
When using a roof luggage carrier (vehicles with roof rails)
Observe the following precautions: ●
Place the cargo so that its weight is distributed evenly between the front and rear
axles. ●
If loading long or wide cargo, never exce ed the vehicle overall length or width.
(  P. 6 0 8 ) ●
Before driving, make sure the cargo is secu rely fastened on the roof luggage carrier.●
Loading cargo on the roof luggage carrier will make the center of gravity of the vehi-
cle higher. Avoid high speeds, sudden starts, sharp turns, sudden braking or abrupt
maneuvers, otherwise it may result in loss of control 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 vehicle 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.

NX300h_U_OM78007UTrailer towing (vehicles with towing package)
Contact your Lexus dealer for further in formation about additional requirements
such as a towing kit, etc.Your vehicle is designed primarily as a passenger-and-load-carrying vehicle.
Towing a trailer can have an adverse impact on handling, performance, brak-
ing, durability, and fuel consumption. Fo r your safety and the safety of others,
you must not overload your vehicle or trailer. You must also ensure that you
are using appropriate towing equipment, that the towing equipment has been
installed correctly and used properly, and that you employ the requisite driv-
ing habits.
Vehicle-trailer stability and braking pe rformance are affected by trailer sta-
bility, brake performance and setting, tr ailer brakes, the hitch and hitch sys-
tems (if equipped).
To tow a trailer safely, use extreme ca re and drive the vehicle in accordance
with your trailer’s characteristics and operating conditions.
Lexus warranties do not apply to damage or malfunction caused by towing a
trailer for commer cial purposes.

GCWR (Gross Combination Weight Rating)
The maximum allowable gross com-
bination weight. The gross combina-
tion weight is the sum of the total
vehicle weight (including the occu-
pants, cargo and any optional equip-
ment installed on the vehicle) and
the weight of the trailer being towed
(including the cargo in the trailer). ■
GVWR (Gross Vehicle Weight Rating)
The maximum allowable gross vehi-
cle weight. The gross vehicle weight
is the total weight of the vehicle.
When towing a trailer, it is the sum of
the vehicle weight (including the
occupants, cargo and any optional
equipment installed on the vehicle)
and the tongue weight. ■
