Trailer towing (vehicles with
towing package)
Your vehicle is de signed primarily
as a passenger-and-load-carrying
vehicle. Towing a trailer can have an
adverse impact on handling, per-
formance, braking, durability, and
fuel consumption. For your safety
and the safety of others, you must
not overload your vehicle or trailer.
You must also ensure that you are
using appropriate towing equip-
ment, that the towing equipment
has been installed correctly and
used properly, and that you employ
the requisite driving habits.
Vehicle-trailer stability and braking
performance are affected by trailer
stability, brake performance and
setting, trailer brakes, the hitch and
hitch systems (if equipped).
To tow a trailer safely, use extreme
care and drive the vehicle in accor-
dance with your trailer’s character-
istics and operating conditions.

■Sensor detectio n information
●The sensor’s detection areas are limited
to the areas around the vehicle’s bumper.
●Certain vehicle conditions and the sur-
rounding environment may affect the
ability of a sensor to correctly detect an
obstacle. Particular instances where this
may occur are listed below.
• There is dirt, snow or ice on the sensor. (Wiping the sensors will resolve this
problem.)
• The sensor is frozen. (Thawing the area will resolve this problem.)
In especially cold weather, if a sensor is
frozen the screen may show an abnormal
display, or obstacles may not be
detected.
• The sensor is covered in any way.
• The vehicle is leaning considerably to one side.
• On an extremely bumpy road, on an incline, on gravel, or on grass.
• The vicinity of the vehicle is noisy due to vehicle horns, motorcycle engines, air
brakes of large vehicles, or other loud
noises producing ultrasonic waves.
• There is another vehicle equipped with parking assist sensors in the vicinity.
• The sensor is coated with a sheet of spray or heavy rain.
• The vehicle is equipped with a fender
pole or wireless antenna.
• Towing eyelets are installed.
• The bumper or sensor receives a strong impact.
• A backlit license plate, license plate holder, etc., are installed.
• The vehicle is approaching a tall or curved curb.
• In harsh sunlight or intense cold weather.
• The area directly under the bumpers is
not detected.
• If obstacles draw too close to the sensor.
• A non-genuine Lexus suspension (low- ered suspension etc.) is installed.
• People may not be detected if they are wearing certain types of clothing.
In addition to the examples above, there are
instances in which, because of their shape,
signs and other objects may be judged by a
sensor to be closer than they are.
●The shape of the obstacle may prevent a sensor from detecting it. Pay particular
attention to the following obstacles:
• Wires, fences, ropes, etc.
• Cotton, snow and other materials that
absorb sound waves
• Sharply-angled objects
• Low obstacles
• Tall obstacles with upper sections pro- jecting outwards in the direction of your
vehicle
●The following situations may occur
during use.
• Depending on the shape of the obstacle and other factors, the detection distance
may shorten, or detection may be impos-
sible.
• Obstacles may not be detected if they
are too close to the sensor.
• There will be a short delay between obstacle detection and display. Even at
slow speeds, there is a possibility that the
obstacle will come within the sensor’s
detection areas befo re the display is
shown and the buzzer sounds.
• Thin posts or object s lower than the sen-
sor may not be detected when
approached, even if they have been
detected once.
• It might be difficult to hear beeps due to
the volume of audio system or air flow
noise of the air conditioning system.

information when replacing tires or
wheels.
■Handling of tires and the suspension
Using tires with any kind of problem or
modifying the suspension will affect the
driving assist systems, and may cause a
system to malfunction.
■Trailer Sway Control precaution
The Trailer Sway Control system is not
able to reduce trailer sway in all situa-
tions. Depending on many factors such
as the conditions of the vehicle, trailer,
road surface and driving environment,
the Trailer Sway Control system may not
be effective. Refer to your trailer owner’s
manual for information on how to tow
your trailer properly.
■If trailer sway occurs
Observe the following precautions.
Failing to do so may cause death or seri-
ous injury.
●Firmly grip the steering wheel. Steer
straight ahead. Do not try to control
trailer sway by turning the steering
wheel.
●Begin releasing the accelerator pedal
immediately but very gradually to
reduce speed.

WARNING
●Always check your brakes for effec-
tiveness immediately after driving in
sand, mud, water or snow.
●After driving through tall grass, mud,
rock, sand, water, etc., check that there
is no grass, bush, paper, rags, stone,
sand, etc. adhering or trapped to the
underbody. Clear off any such matter
from the underbody. If the vehicle is
used with these materials trapped or
adhering to the underbody, a break-
down or fire could occur.
●When driving off-road or in rugged
terrain, do not drive at excessive
speeds, jump, make sh arp turns, strike
objects, etc. This may cause loss of
control or vehicle rollover causing
death or serious injury. You are also
risking expensive damage to your
vehicle’s suspension and chassis.
NOTICE
■To prevent water damage
Take all necessary sa fety measures to
ensure that water da mage to the hybrid
battery (traction battery), hybrid system
or other components does not occur.
●Water entering the engine compart-
ment may cause severe damage to the
hybrid system. Water entering the inte-
rior may cause the hybrid battery
stowed under the rear seats to short
circuit.
●Water entering the hybrid transmis-
sion and rear electr ic motor (traction
motor) will cause deterioration in
transmission quality. The malfunction
indicator may come on, and the vehi-
cle may not be drivable.
●Water can wash the grease from wheel
bearings, causing rusting and prema-
ture failure, and may also enter the
hybrid transmission case, reducing the
gear oil’s lubricating qualities.
■When you drive through water
If driving through water, such as when
crossing shallow streams, first check the
depth of the water and the bottom of the
riverbed for firmness. Drive slowly and
avoid deep water.
■Inspection after off-road driving
●Sand and mud that has accumulated
around brake discs may affect braking
efficiency and may damage brake sys-
tem components.
●Always perform a maintenance
inspection after each day of off-road
driving that has taken you through
rough terrain, sand, mud, or water. For
scheduled maintena nce information,
refer to the “Warranty and Services
Guide/Owner’s Manual Supplement/
