Cargo and luggage Cargo capacity depends on the total weight of the occupants.
(Cargo capacity) = (Total load capacity) − (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 th e driver and passengers that will be rid-
ing in your vehicle.
(3) Subtract the combined weight of th e 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 amou nt 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 tra iler 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. 186)Take notice of the following informat ion about storage precautions, cargo
capacity and load:

Driving Cargo capacity
Total load capacity (vehicle capacity
weight) ( → P. 558)
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 w ill 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 nu mber 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 increa se in the number of
occupants causes an excess of the total load capacity (combined weight of occu-
pants plus cargo and luggage load), yo u must reduce the cargo and luggage on
your vehicle. Calculation formula for your vehicle 1

WARNING ■
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 passeng ers, 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. ●
Do not place cargo or luggage in or on the following locations.
• At the feet of the driver
• On the front passenger or re ar seats (when stacking items)
• On the luggage cover (if equipped)
• On the instrument panel
•On the dashboard
• On the auxiliary box or tray that has no lid ●
Secure all items in the occupant compartment. ●
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 seat belts properly fastened. Other-
wise, they are much more likely to suffer de ath or serious bodily injury, in the event of
sudden braking, sudden swerving or an accident. ■
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 whic h may cause death or serious injury.

Vehicle load limits ◆ Total load capacity (vehicle capacity weight): → P. 558
Total load capacity means the combined weight of occupants, cargo and lug-
gage.
◆ Seating capacity:
Vehicles with third seats: 8 occupants (Front 2, Rear 6)
Vehicles without third seats: 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): → P. 191, 558
TWR means the maximum gross trailer we ight (trailer weight plus its cargo
weight) that your vehicle is able to tow.
◆ Cargo capacity
Cargo capacity may increase or decrease 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. 495)Vehicle load limits include total load capacity, seating capacity, TWR (Trailer
Weight Rating) and cargo capacity.
WARNING ■
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.

WARNING ■
Trailer towing precautions ●
To tow a trailer safely, use extreme care an d drive the vehicle in accordance with the
trailer’s characteristics and operating condit ions. Failure to do so could cause an acci-
dent resulting in death or serious injury. Vehicle stability and braking performance are
affected by trailer st ability, brake setting and performanc e, and the hitch. Your vehicle
will handle differently when towing a trailer. ●
Set the vehicle height to the “LO” mode and turn off the 4-Wheel AHC when you
connect a trailer, otherwise the vehicle height may change due to the automatic level-
ing function, and you may catch part of your body in the vehicle, resulting in an acci-
dent. ( → P. 295)■
To avoid accident or injury ●
Do not exceed the TWR, unbraked TWR, GCWR, GVWR or GAWR. ●
If the gross trailer weight is over 2000 lb. (907 kg), a sway control device with suffi-
cient capacity is required. ●
If the gross trailer weight is over 5000 lb. (2268 kg), a weight distributing hitch with
sufficient capacity is required. ●
Adjust the tongue weight within the approp riate range. Place heavier loads as close
to the trailer axle as possible. ●
Do not exceed 65 mph (104 km/h), the posted towing speed limit or the speed limit
for your trailer as set forth in your trai ler owner’s manual, whichever is lowest. Slow
down sufficiently before making a turn, in crosswinds, on wet or slippery surface, etc.
to help avoid an accident. If you experien ce a vehicle-trailer in stability from reducing
a certain speed, slow down and make sure you keep your vehicle speed under the
speed of which you expe rience the instability.●
Do not make jerky, abrupt or sharp turns. ●
Do not apply the brakes suddenly as you ma y skid, resulting in jackknifing and loss of
vehicle control. This is especially true on wet or slippery surfaces.●
Do not exceed the trailer hitch assembly weight, gross vehicle weight, gross axle
weight and trailer tongue weight capacities. ●
Do not use cruise control (if equipped) or dynamic radar cruise control with full-
speed range (if equipped) when trailer towing. ●
Slow down and downshift before descending steep or long downhill grades. Do not
make sudden downshifts while descending steep or long downhill grades. ●
Vehicle-trailer instability is more likely on steep long down hills. Before descending
steep or long downhill grades, slow down and downshift. Do not make sudden down-
shifts when descending steep or long do wnhill grades. Avoid ho lding the brake pedal
down too long or applying the brakes too frequently. This could cause the brakes to
overheat and result in reduced braking efficiency.

Tire types ●
Summer tires
Summer tires are high-speed performance ti res best suited to highway driving under
dry conditions. Since summer tires do not have the same traction performance as
snow tires, summer tires are inadequate for driving on snow-covered or icy roads. For
driving on snow-covered roads or icy road s, the use of snow tires is recommended.
When installing snow tires, be sure to replace all four tires.●
All season tires
All season tires are designed to provide better traction in snow and to be adequate for
driving in most winter conditions, as well as for use year round. All season tires, how-
ever, do not have adequate traction perfor mance compared with snow tires in heavy
or loose snow. Also, all season tires fall short in acceleration and handling perfor-
mance compared with summer tires in highway driving.●
Snow tires
For driving on snow-covered roads or icy roads, we recommend using snow tires. If
you need snow tires, select ti res of the same size, construction and load capacity as the
originally installed tires. Since your vehicle has radial tires as or iginal equipment, make
sure your snow tires also have radial cons truction. Do not install studded tires without
first checking local regulations for possible re striction. Snow tires should be installed
on all wheels. ( → P. 382)■
Initializing the tire pressure warning system
Initialize the tire pressure warn ing system with the tire inflat ion pressure adjusted to the
specified level. ■
If the tread on snow tires wears down below 0.16 in. (4 mm)
The effectiveness of the tire s as snow tires is lost.■
If you press the tire pressure warning reset switch accidentally
If initialization is performed, adjust the tire inflation pressure to the specified level and ini-
tialize the tire pressure warning system again.■
Situations in which the tire pressure warning system may not operate properly ●
In the following cases, the tire pressure warning system may not operate properly.
• If non-genuine Lexus wheels are used.
• A tire has been replaced with a tire that is not an OE (Original Equipment) tire.
• A tire has been replaced with a tire that is not of the specified size.
• Tire chains etc. are equipped.
• An auxiliary-supported run-flat tire is equipped.
• If a window tint that affects th e radio wave signals is installed.
• If there is a lot of snow or ice on the vehi cle, particularly around the wheels or wheel
housings.
• If the tire inflation pressure is extr emely higher than the specified level.
• If the spare tire is in a location subj ect to poor radio wave signal reception.
• If a large metallic object which can interfer e with signal reception is put near the
spare tire.
• If tires not equipped with the tire pressure warning valves and transmitters are used.
• If the ID code on the tire pressure warning valves and transmitters is not registered
in the tire pressure warning computer.

Maintenance and care
Wheels When replacing wheels, care should be ta ken to ensure that they are equivalent
to those removed in load capacity, diameter, rim width, and inset
* .
Replacement wheels are available at your Lexus dealer.
* : Conventionally referred to as “offset”.
Lexus does not recommend using the following:●
Wheels of different sizes or types ●
Used wheels ●
Bent wheels that have been straightened ●
Use only Lexus wheel nuts and wrenches designed for use with your alumi-
num wheels. ●
When rotating, repairing or changing your tires, check that the wheel nuts are
still tight after driving 1000 miles (1600 km). ●
Be careful not to damage the aluminum wheels when using tire chains. ●
Use only Lexus genuine balance weights or equivalent and a plastic or rubber
hammer when balancing your wheels. ■
When replacing wheels
The wheels of your vehicle are equipped with tire pressure warning valves and transmit-
ters that allow the tire pressure warning system to provide advance warning in the event
of a loss in tire inflation pressure. Whenever wheels are replaced, tire pressure warning
valves and transmitters must be installed. ( → P. 487)If a wheel is bent, cracked or heavil y corroded, it should be replaced.
Otherwise, the tire may separate from the wheel or cause loss of handling
control.
