■Automatic cruise control cancelation
The set speed is automatically canceled in any of the following situations.
●Actual vehicle speed falls more than 10 mph (16 km/h) below the preset vehicle
speed
At this time, the memorized set speed is not retained.
●Actual vehicle speed is below 25 mph (40 km/h)
●Enhanced VSC is activated
■If the cruise control indicator light flashes
Press the “ON-OFF” button off once, and then reactivate the system. 
If the cruise control speed cannot be set or if the cruise control cancels immediately
after being activated, there may be a malfunction in the cruise control system. Have
the vehicle inspected by your Lexus dealer.
CAUTION
■To avoid operating the cruise control by mistake
Keep the “ON-OFF” button off when not in use.
■Situations unsuitable for cruise control
Do not use cruise control in any of the following situations.
Doing so may result in control of the vehicle being lost and could cause an accident
resulting in death or serious injury.
●In heavy traffic
●On roads with sharp bends
●On slippery roads, such as those covered with rain, ice or snow
●On steep hills
Vehicle speed may exceed the set speed when driving down a steep hill.
●On winding roads
●When emergency towing

CAUTION
■Situations unsuitable for dynamic radar cruise control
Do not use dynamic radar cruise control in any of the following situations.

Doing so may result in inappropriate speed control and could cause an accident
resulting in death or serious injury.
●In heavy traffic
●On roads with sharp bends
●On winding roads
●On slippery roads, such as those covered with rain, ice and snow
●On steep downhills, or where there are sudden changes between sharp up and
down gradients
Vehicle speed may exceed the set speed when driving down a steep hill.
●At entrances to expressways
●When weather conditions are bad enough that they may prevent the sensors
from functioning correctly (fog, snow, sandstorm, heavy rain, etc.)
●When an approach warning buzzer is heard often
●During emergency towing
■When the sensor may not be correctly detecting the vehicle ahead
Apply the brakes as necessary when any of the following types of vehicles are in
front of you.
As the sensor may not be able to correctly detect these types of vehicles, the
approach warning (P. 178) will not be activated, and a fatal or serious accident
may result.
●Vehicles that cut in suddenly
●Vehicles traveling at low speeds
●Vehicles that are not moving
●Vehicles with small rear ends (trailers with no load on board etc.)
●Motorcycles traveling in the same lane

●In the following situations, the intuitive parking assist may not function correctly,
possibly leading to an accident.
• There is ice, snow or mud on the sensors. (Wiping the sensors will resolve this
problem.)
• The sensor area is frozen. (Thawing the area will resolve this problem.)
In especially cold weather, if a sensor is frozen the screen may show an abnor-
mal display, or obstacles may not be detected.
• The vehicle angle is especially wide.
• In harsh sunlight or intense cold weather.
• When driving on bumpy, sloped or gravel roads, or over grass.
• If there is something producing ultrasonic waves nearby, such as another
vehicle’s horn, motorcycle engine noise, air braking sound from heavy-duty
vehicles, or another vehicle using the intuitive parking assist.
• In heavy rain, or if water is splashed on the sensors.
• If a commercial fender pole or radio antenna is installed.
• If towing eyelet is installed on your vehicle.
• If moving towards a high curb or a curb corner.
• Objects such as signs may cause the detection distance to shorten.
• The area directly under the bumpers is not detected.
Objects lower than the sensors or thin stakes etc. may be detected initially,
but as they draw closer, they may cease to be detected.
• If obstacles draw too close to the sensor.
■Obstacles that may not be detected correctly
The following obstacles may not be detected.
●Thin objects such as wire, fencing or rope.
●Objects that absorb sound waves, such as cotton or snow.
●Objects with sharp corners.
●Objects where the upper section projects out over the lower section.
●Low objects.
■If the display flashes and a message is displayed
P. 552
■Warning beep volume and touch screen settings
You can change the warning beep volume etc. (P. 245)

Capacity and distribution
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 available amount of cargo and lug-
gage 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.
(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
vehicle. (P. 218)
Lexus does not recommend towing a trailer with your vehicle. Your vehicle
is not designed for trailer towing.

Vehicle load limits
■Total load capacity and seating capacity
These details are also described on the tire and loading information label. 
(P. 4 7 3 )
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: 815 lb. (370 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
estimated average weight is 150 lb. (68 kg) per person.
Even if the number of occupants are within the seating capacity, do
not exceed the total load capacity.
■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.

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 wheelchair, scooter, bicycle, etc. Your Lexus is not designed
for trailer towing or for the use of tow hitch mounted carriers.
