LS500_OM_(U)_1810 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-NOTICE

Driving WARNING●
Keep the radar sensors and their sur-
rounding areas on the front bumper
clean at all times.
If a radar sensor or its surrounding area
on the front bumper is dirty or covered
with snow, the system may not operate
and a warning message ( P.428) will be
displayed.
If this occurs, clean off the dirt or snow
and drive the vehicle for approximately
10 minutes.
If the warning message does not disap-
pear, have your vehicle inspected by your

to a strong impact.
If a radar sensor is moved even slightly
off position, the system may malfunction
and vehicles may not be detected cor-
rectly.
In the following situations, have your
vehicle inspected by your Lexus dealer.
• If a radar sensor or its surrounding
area is subject to a strong impact
• If the area on the front bumper around
a radar sensor is scratched or dented,
or the front bumper has become par-
tially disengaged ●
Do not disassemble the radar sensors. ●
Do not modify the radar sensors or
their surrounding area on the front
