IS350/250_U (OM53758U)
■When driving position memory is linked with door unlock operation
If the driver’s door is opened, the driver’s seat will move toward the memorized position
but stop slightly beforehand to allow easy access to the vehicle.
Turning the engine switch to ACCESSORY or IGNITION ON mode, or fastening the
driver’s seat belt moves the seat fully into the memorized position.
■Operating the driving position memory after turning the engine switch off
Memorized seat positions can be activated up to 180 seconds after the driver’s door is
opened and another 60 seconds after it is closed again. Memorized steering wheel posi-
tion can be activated by pr essing the engine switch.
■Correct seat position
When the seat is in the most forward or mo st backward position, and the seat is being
moved in those directions, the system may not correctly recognize the current position
and the memorized position will not be correctly recalled.
■The auto away function for exiting
If the seat is already close to the rearmost position, the auto away function may not oper-
ate when the driver exits the vehicle.
■When the driving position is recalled by a memory linked door unlock operation
●Since each memorized driving position is regi stered to a specific electronic key, the
driving position recalled may be different depending on the carried key.
●When only doors other than the driver’s d oor are unlocked by the smart access system
with push-button start, the driving position will not be recalled. In this case, press a driv-
ing position memory button to recall the desired driving position.
■Customization
The distance that the driver’s seat moves b ackward during the auto away function can be
changed. (Customizable features: P. 5 2 5 )
CAUTION
■Seat adjustment caution
Take care during seat adjustment so that th e seat does not strike the rear passenger or
squeeze your body against the steering wheel.

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 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 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 am ount 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 trailer 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. 1 5 6 )
Lexus does not recommend towing a trailer with your vehicle. Your vehicle is not
designed for trailer towing.

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.
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 passengers, possibly causing
an accident.
●Stow cargo and luggage in the trunk whenever possible.
●To prevent cargo and luggage from sliding forward during braking, do not stack any-
thing in the enlarged trunk. Keep cargo and luggage low, as close to the floor as pos-
sible.
●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 enlarged trunk. It is not designed for passengers.
They should ride in thei r seats with their seat belts properly fastened.
●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 navigation system scre en (if equipped) or Lexus Display Audio
screen (if equipped)
●Secure all items in th e occupant compartment.
■Capacity and distribution
●Do not exceed the maximum axle weight ra ting 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.

◆Total load capacity (vehicle capacity weight): ( P. 500)
Total 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 occupants whose estimated
average weight is 150 lb. (68 kg) per person.
◆To w i n g c a p a c i t y
Lexus does not recommend towing a trailer with your vehicle.
◆Cargo capacity
Cargo capacity may increase or decrea se 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. 4 2 0 )
Vehicle load limits
Vehicle load limits include total load capacity, seating capacity, towing capac-
ity and cargo capacity.
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.
