For the first 500 miles (800 km):
Do not tow a trailer. ●
For the first 1000 miles (1600 km):
• Do not drive at extremely high speeds.
• Avoid sudden acceleration.
• Do not drive continuously in low gears.
• Do not drive at a constant speed for extended periods. ■

RX350_U_OM48E90U 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 am ount 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. 2 0 4 ) Vehicles without towing package: Lexus does not recommend towing a trailer with
your vehicle. Your vehicle is not designed for trailer towing.Cargo and luggage Take notice of the following information about storage precautions, cargo
capacity and load.

RX350_U_OM48E90U ◆ Total load capacity (vehicle capacity weight): P. 6 74
Total load capacity means the combined weight of occupants, cargo and lug-
gage.
◆ Seating capacity: 5 occupants (Front 2, Rear 3)
Seating capacity means the maximum number of occupants whose estimated
average weight is 150 lb. (68 kg) per person.
◆ TWR (Trailer Weight Rating) (vehicles with towing package):
P. 2 0 8 , 6 74
TWR means the maximum gross trailer weight (trailer weight plus its cargo
weight) that your vehicle is able to tow.
◆ TWR (Trailer Weight Rating) (vehicles without towing package)
Lexus does not recommend towing a trailer with your vehicle.
◆ Cargo capacity
Cargo capacity may increase or decrea se depending on the weight and the
number of occupants. ■
Total load capacity and seating capacity
These details are also described on the tire and loading information label. ( P. 5 9 3 )Vehicle load limits Vehicle load limits include total load capacity, seating capacity, trailer weight
rating and cargo capacity.

Overloading the vehicle
Do not overload the vehicle.
It may not only cause damage to the tires, but also degrade steering and braking ability,
resulting in an accident.

Driving
RX350_U_OM48E90U Contact your Lexus dealer for further in formation about additional requirements
such as a towing kit, etc.Trailer towing (vehicles with towing package) 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. ■
GAWR (Gross Axle Weight Rating)
The maximum allowable gross axle
weight. The gross axle weight is the
load placed on each axle (front and
rear).Towing related terms

TWR (Trailer Weight Rating)
The maximum allowable gross trailer
weight. The gross trailer weight is
the sum of the trailer weight and the
weight of the cargo in the trailer.
TWR is calculated assuming base
vehicle with one driver, one front
passenger, towing package (if avail-
able), hitch and hitch systems (if
required). Additional optional equipment, passengers and cargo in the vehicle will reduce the
trailer weight rating so as not to exceed GCWR, GVWR and GAWR.
If the gross trailer weight exceeds 3000 lb. (1360 kg), it is recommended to use a
trailer with 2 or more axles.■
Unbraked TWR (Unbraked Trailer Weight Rating)
The trailer weight rating for towing a
trailer without a trailer service brake
system.
