■Drum-in-disc type parking brake system
Your vehicle has a drum-in-disc type parking brake system. This type of brake system
needs bedding-down of the brake shoes peri odically or whenever the parking brake
shoes and/or drum are replaced. Have your Lexus dealer perform the bedding down
operation.
■Operating your vehicle in a foreign country
Comply with the relevant vehicle registration laws and confirm the availability of the cor-
rect fuel. ( →P. 587)
■Idling time before engine stop (IS200t)
To prevent damage to the turbocharger, allow the engine to idle immediately after high-
load driving.
Driving conditionIdling time
Normal city driving or high-spe ed driving (at the highway speed
limit or recommended speed)

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 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 th e driver and passengers that will be rid-
ing in your vehicle.
(3) Subtract the combined weight of th e 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 amou nt 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. 169)
Lexus does not recommend towing a trailer with your vehicle. Your vehicle is not
designed for trailer towing.

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

■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 lugg age 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 their 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 re ar seats (when stacking items)
• On the package tray
• On the instrument panel
•On the dashboard
• In front of the Lexus Display Audio scre en (if equipped) or navigation system
screen (if equipped)
●Secure all items in the occupant compartment.
■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 whic h may cause death or serious injury.

●Bicycles or similar vehicles may not be detected.
●In the following situations the system may not be able to correctly detect the surround-
ing brightness level. 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 necessary 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 damaged
• 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 headlights, 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 intermittently changing brightness and darkness

■Raindrop sensor (vehicles with rain-sensing windshield wipers)
●If the wiper is turned to AUTO mode wh ile the engine switch is in IGNITION ON
mode, the wipers will operate once to show that AUTO mode is activated.
●If the temperature of the raindrop sensor is 185°F (85°C) or higher, or -22°F (-30°C)
or lower, automatic operation may not occur. In this case, operate the wipers in any
mode other than AUTO mode.
■When the windshield wipers are in tempor ary operation (vehicles with rain-sensing
windshield wipers)
AUTO mode cannot be activa ted even if is pressed.
■If no windshield washer fluid sprays
Check that the washer nozzles are not blocked if there is washer fluid in the windshield
washer fluid reservoir.
●The raindrop sensor judges the amount of
raindrops.
An optical sensor is adopted. It may not oper-
ate properly when sunlight from the rising or
setting of the sun inte rmittently strikes the
windshield, or if bugs etc. are present on the
windshield.
