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.
(
P.168)
Lexus does not recommend towing a
trailer with your vehicle. Your vehicle is not
designed for trailer towing.
Cargo capacity
Total load capacity (vehicle capac-
ity weight) ( P.458)
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
Cargo and luggage

Driving
*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 lug-
gage on your vehicle.
WARNING
■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 Center Display
●Secure all items in the occupant com-
partment.
■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.

Maintenance and care
■When to replace your vehicle’s tires
Tires should be replaced if:
●The treadwear indicators are showing on
a tire.
●You have tire damage such as cuts, splits,
cracks deep enough to expose the fabric,
and bulges indicating internal damage
●A tire goes flat repeatedly or cannot be
properly repaired due to the size or loca-
tion of a cut or other damage
If you are not sure, consult with your Lexus
dealer.
■Tire life
Any tire over 6 years old must be checked
by a qualified technician even if it has sel-
dom or never been used or damage is not
obvious.
■Maximum load of tire
Check that the maximum load of the
replacement tire is greater than 1/2 of the
Gross Axle Weight Ratings (GAWR) of
either the front axle or the rear axle, which-
ever is greater.
For the GAWR, see the Certification Label.
For the maximum load of the tire, see the
load limit at maximum cold tire inflation
pressure mentioned on the sidewall of the
tire. ( P.470)
■Tire types
●Summer tires
Summer tires are high-speed performance
tires 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 roads, the use of snow tires is recom-
mended. 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,
however, do not have adequate traction
performance compared with snow tires in
heavy or loose snow. Also, all season tires
fall short in accelerati on and handling per-
formance 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 tires of the
same size, construction and load capacity
as the originally instal led tires. Since your
vehicle has radial tires as original equip-
ment, make sure your snow tires also have
radial construction. Do not install studded
tires without first checking local regula-
tions for possible restrictions. Snow tires
should be installed on all wheels.
(  P.309)
■If the tread on snow tires wears down
below 0.16 in. (4 mm)
The effectiveness of the tires as snow tires is
lost.
WARNING
■When inspecting or replacing tires
Observe the following precautions to
prevent accidents.
Failure to do so may cause damage to
parts of the drive train as well as danger-
ous handling characteristics, which may
lead to an accident resulting in death or
serious injury.

■The tire pressure warning system
must be initialized in the following
circumstances:
 When the tire inflation pressure is
changed such as when changing
traveling speed or load weight.
 When the tire inflation pressure is
changed such as when the tire size
is changed.
 When rotating the tires.
 After performing the transmitter ID
code registration procedure.
( P.399)
When the tire pressure warning system
is initialized, the cu rrent tire inflation
pressure is set as the benchmark pres-
sure.
■How to initialize the tire pressure
warning system
1 Park the vehicle in a safe place, turn
the power switch off and wait 20
minutes or more.
The initialization procedure cannot be
started while the vehicle is moving.
2Adjust the tire inflation pressure to
the specified cold tire inflation pres-
sure level.
Make sure to adjust th e tire pressure to the
specified cold tire infl ation pressure level.
The tire pressure warning system will oper-
ate based on this pressure level.
3 Start the hybrid system.
4 Press or of the meter con-
trol switch to select . 5
Press or to select “Vehicle
Settings” and then press .
6 Press or to select “TPWS”
and then press .
7 Press or to select “Set
Pressure”. Then press and hold
until the tire pressure warning light
blinks 3 times.
Then a message will be displayed on the
multi-information display.
“---” will be displayed on the multi-informa-
tion display for the inflation pressure of
each tire while initialization is being per-
formed.
8Drive straight (with occasional left
and right turns) at approximately
25 mph (40 km/h) or more for
approximately 10 to 30 minutes.
Initialization is comple te when the position
of each tire is determ ined and the inflation
pressure of each tire is displayed on the
multi-information display.
Initialization may take longer than normal
to complete if the vehicle speed cannot be
maintained at approx imately 25 mph (40
km/h) or more. If initialization cannot be
completed after driving for 1 hour or more,
park the vehicle in a safe place, turn the
power switch off and wait 20 minutes or
more before performing the driving proce-
dure again. ( P.399)

warning system

4066-3. Do-it-yourself maintenance
LS500h_OM_(U)_1809ing.
●Always use a tire pressure gauge.
It is difficult to judge if a tire is properly
inflated based only on its appearance.
●It is normal for the tire inflation pressure
to be higher after driving as heat is gen-
erated in the tire. Do not reduce tire infla-
tion pressure after driving.
●Never exceed the vehicle capacity
weight.
Passengers and luggage weight should
be placed so that the vehicle is balanced.
When replacing wheels, care should
be taken to ensure that they are equiv-
alent to those removed in load capac-
ity, 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 straight-
ened
■When replacing wheels
The wheels of your vehicle are equipped
with tire pressure wa rning valves and trans-
mitters 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, the tire
pressure warning valves and transmitters
must be installed. ( P.397)
WARNING
■Proper inflation is critical to save tire
performance
Keep your tires properly inflated.
If the tires are not properly inflated, the
following conditions may occur which
could lead to an accident resulting in
death or serious injury:
●Excessive wear
●Uneven wear
●Poor handling
●Possibility of blowouts resulting from
overheated tires
●Air leaking from between tire and
wheel
●Wheel deformation and/or tire dam-
age
●Greater possibility of tire damage
while driving (due to road hazards,
expansion joints, sharp edges in the
road, etc.)
NOTICE
■When inspecting and adjusting tire
inflation pressure
Be sure to put the tire valve caps back on.
If a valve cap is not installed, dirt or mois-
ture may get into the valve and cause an
air leak, resulting in decreased tire infla-
tion pressure.
Wheels
If a wheel is bent, cracked or heavily
corroded, it should be replaced.
Otherwise, the tire may separate
from the wheel or cause a loss of
handling control.

WARNING
■When replacing wheels
●Do not use wheels that are a different
size from those recommended in the
Owner’s Manual, as this may result in a
loss of handling control.
