LS500h_OM_OM50F42U_(U) 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 co mbined 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.166) 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.460)
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

Total load capacity and seating capacity
These details are also described on the tire
and loading information label. ( → P.408)Vehicle load limits Vehicle load limits include total
load capacity, seating capacity,
towing capacity and cargo capac-
ity.
 Total load capacity (vehicle
capacity weight): → P.460Total 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 occupant s whose estimated
average weight is 150 lb. (68 kg) per
person.
 Towing capacity Lexus does not recommend towing a
trailer with your vehicle.
 Cargo capacity Cargo capacity may increase or
decrease depending on the weight and
the number of occupants.
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. Trailer towing Lexus does not recommend towing
a trailer with your vehicle. Lexus
also does not recommend the
installation of a tow hitch or the use
of a tow hitch carrier for a wheel-
chair, scooter, bicycle, etc. Your
vehicle is not desi gned for trailer
towing or for the use of tow hitch
mounted carriers.

Driving vehicle ahead that is using fog lights with-
out its headlights turned on is detected.●
House lights, street lig hts, traffic signals,
and illuminated billboards or signs and
other reflective objects may cause the
high beams to change to the low beams,
or the low beams to remain on.●
The following factors may affect the
amount of time taken for the high beams
to turn on or off:
• The brightness of the headlights, fog
lights, and tail lights of vehicles ahead
• The movement and direction of vehicles
ahead
• When a vehicle ahead only has opera-
tional lights on one side
• When a vehicle ahead is a two-wheeled
vehicle
• The condition of the road (gradient,
curve, condition of th e road surface, etc.)
• The number of passengers and amount of
luggage in the vehicle●
The high beams may turn on or off unex-
pectedly.●
Bicycles or similar vehicles may not be
detected.●
In the following situations the system may
not be able to correctly detect the sur-
rounding brightness le vel. This may cause
the low beams to remain on or the high
beams to flash or dazzle pedestrians or
vehicles ahead. In such a case, it is neces-
sary to manually switch between the high
and low beams.
• When driving in inclement weather
(heavy rain, snow, fog, sandstorms, etc.)
• When the windshield is obscured by fog,
mist, ice, dirt, etc.
• When the windshield is cracked or dam-
aged
• When the camera sensor is deformed or
dirty
• When the temperature of the camera
sensor is extremely high
• When the surrounding brightness level is
equal to that of head lights, tail lights or
fog lights
• When headlights or tail lights of vehicles
ahead are turned off, dirty, changing
color, or not aimed properly
• When the vehicle is hit by water, snow,
dust, etc. from a preceding vehicle • When driving through an area of inter-
mittently changing brightness and dark-
ness
• When frequently and repeatedly driving
ascending/descending roads, or roads
with rough, bumpy or uneven surfaces
(such as stone-paved roads, gravel roads,
etc.)
• When frequently and repeatedly taking
curves or driving on a winding road
• When there is a highly reflective object
ahead of the vehicle, such as a sign or
mirror
• When the back of a preceding vehicle is
highly reflective, such as a container on a
truck
• When the vehicle’s headlights are dam-
aged or dirty, or are not aimed properly
• When the vehicle is listing or titling due to
a flat tire, a trailer being towed, etc.
• When the headlights are changed
between the high beams and low beams
repeatedly in an abnormal manner
• When the driver believes that the high
beams may be flashing or dazzling
pedestrians or other drivers ■
Temporarily lowering sensor sensitivity
The sensitivity of the sensor can be tempo-
rarily lowered.
1 Turn the power switch on while the fol-
lowing conditions are met.
●
The headlight switch is in or . ●
The headlight switch lever is in high beam
position. ●
Automatic High Beam switch is on.
2 Turn the power switch to ON mode.
3 Within 30 seconds after step 2 , repeat
pulling the headlight switch lever to the
original position then pushing it to the
high beam position quickly 10 times,
then leave the lever in high beam posi-
tion.
4 If the sensitivity is changed, the AHB
indicator is turn on and off 3 times.
Automatic High Beam (headlights) may
turn on even when the vehicle is stopped.

Driving ■
Warning messages and buzzers for
dynamic radar cruise control with
full-speed range
Warning messages and buzzers are used to
indicate a system malfunction or to inform
the driver of the need for caution while driv-
ing. If a warning message is shown on the
multi-information display, read the message
and follow the instructions. ■
When the sensor may not be correctly
detecting the vehicle ahead
In the case of the following and depending
on the conditions, operate the brake pedal
when deceleration of the system is insuffi-
cient or operate the accelerator pedal
when acceleration is required.
As the sensor may not be able to correctly
detect these types of vehicles, the approach
warning ( → P.256) may not be activated.●
Vehicles that cut in suddenly●
Vehicles traveling at low speeds●
Vehicles that are not moving in the same
lane●
Vehicles with small rear ends (trailers
with no load on board, etc.)
●
Motorcycles travelin g in the same lane●
When water or snow thrown up by the
surrounding vehicles hinders the detect-
ing of the sensor
●
When your vehicle is pointing upwards
(caused by a heavy load in the luggage
compartment, etc.) ●
Preceding vehicle has an extremely high
ground clearance
■
Conditions under which the vehi-
cle-to-vehicle dist ance control mode
may not function correctly
In the case of the following conditions,
operate the brake pedal (or accelerator
pedal, depending on the situation) as nec-
essary.
As the sensor may not be able to correctly
detect vehicles ahead, the system may not
operate properly. ●
When driving around a curve, on a nar-
row road, or on a bridge, in a tunnel, etc.,
where there are objects on the roadside
●
When steering wheel operation or your
position in the lane is unstable
●
When the vehicle ahead of you deceler-
ates suddenly
●
While the vehicle speed is decreasing to
the set speed after the vehicle acceler-
ates by depressing the accelerator pedal.
