CAUTION
■Before using the LKA system
Do not rely on the LKA system to remain within a selected lane. The LKA system is
not designed to enable inattentive driving. The steering wheel should be operated
by the driver to maintain the vehicle in a suitable position within its lane. Always
drive carefully.
■Turn the LKA off while driving in any of the following conditions:
Do not use LKA in any of the following situations.
Otherwise, the system may not function correctly and could result in an accident.
●When driving with snow tires, snow chains, a spare tire, or similar equipment.
●When driving with non-standard parts or aftermarket equipment installed.
(including modified tires and suspensions, etc.)
●When towing a trailer.
●When there are objects or structures along the roadside that might be misinter-
preted as lane markers. (such as guardrails, curb, reflector posts, etc.)
●When there are wheel ruts, icy trademarks, etc. or if snow remains on the road
surface.
●When there are shadows on the road running parallel with lane markers, or if a
shadow covers the lane markers.
●When there are visible lines on the pavement from road repairs, or if the remains
of old lane markers are still visible on the road.
●When driving on slippery roads, such as those covered with rain, ice or snow.
●When driving in a lane other than the driving or passing lanes on a freeway or
highway.
●When driving on a road with lane closures due to maintenance, or when driving
in a temporary lane.
●When driving on winding roads or roads that are rough or uneven.

Cargo and luggage
Capacity and distributionCargo capacity depends on the total weight of the occupants.
(Cargo capacity) = (Total load cap acity) — (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 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 luggage load capacity calculated in Step 4.
Take notice of the following information about storage precautions, cargo
capacity and load:
●Stow cargo and luggage in the trunk whenever possible.
● Be sure all items are secured in place.
● To maintain vehicle balance while driving, position luggage evenly
within the luggage compartment.
● For better fuel economy, do not carry unnecessary weight.

When driving
HS250h_U_75033U(Canada)(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 luggage load capacity of your vehi-
cle. ( →P. 243)
Lexus does not recommend towing a trailer with your vehicle. Your vehicle is
not designed for trailer towing.
Example based on your vehicle
Cargo capacity
Total load capacity
When 2 people with the combined weight of 366 lb. (166 kg) are riding
in your vehicle, which has a total load capacity of 825 lb. (375 kg), the
available amount of cargo and luggage load capacity will be as follows:
825 lb. — 366 lb. = 459 lb. (375 kg —166 kg = 209 kg)
In this condition, if 3 more passengers with the combined weight of 388 lb.
(176 kg) get on, the available cargo and luggage load will be reduced as fol-
lows:
459 lb. — 388 lb. = 71 lb. (209 kg — 176 kg = 33 kg)
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 occupants plus cargo and luggage load),
you must reduce the cargo and luggage on your vehicle.

CAUTION
■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.
Failing to do so may result in death or serious injury.
●Stow cargo and luggage in the trunk whenever possible.
●Do not place cargo or luggage in or on the following locations as the item may
get under the brake or accelerator pedal and prevent the pedals from being
depressed properly, block the driver’s vision, or hit the driver or passengers,
causing an accident:
• 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
●Secure all items in the occupant compartment, as they may shift and injure some-
one during 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 dete-
rioration of steering or braking control which may cause death or serious injury.

Vehicle load limits
■Total load capacity and seating capacity
These details are also described on the tire and loading information label.
(→ P. 4 4 5 )
CAUTION
■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.
Vehicle load limits include total load capacity, seating capacity, towing
capacity and cargo capacity.
■Total load capacity: 825 lb. (375 kg)
Total load capacity means the combined weight of occupants, cargo and
luggage.
■Seating capacity: 5 occupants (Front 2, Rear 3)
Seating capacity means the maximum number of occupants whose esti-
mated 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.
