■Before towing
Check that the following conditions
are met:
●Ensure that your vehicle’s tires
are properly inflated. ( P.555)
●Trailer tires are inflated according
to the trailer manufacturer’s rec-
ommendation.
●All trailer lights work as required
by law.
●All lights work each time you con-
nect them.
●The trailer ball is set at the proper
height for the coupler on the
trailer.
●The trailer is level when it is
hitched. Do not dri ve if the trailer
is not level, and check for
improper tongue weight, overload-
ing, worn suspension, or other
possible causes.
●The trailer cargo is securely
loaded.
●The rear view mirrors conform to
all applicable federal, state/provin-
cial or local regu lations. If they do
not, install rear view mirrors
appropriate for towing purposes.
Contact your Toyota dealer for
further information about addi-
tional requirements such as a
towing kit, etc.WARNING
■Trailer towing precautions
●To tow a trailer safely, use
extreme care and drive the vehi-
cle in accordance with the
trailer’s characteristics and
operating conditions. Failure to
do so could cause an accident
resulting in death or serious
injury. Vehicle stability and brak-
ing performance are affected by
trailer stability, brake setting and
performance, and the hitch.
Your vehicle will handle differ-
ently when towing a trailer.
●Vehicles with electronically
modulated air suspension: Set
the vehicle height to the “N”
mode and turn off the rear
height control air suspension
when you connect a trailer, oth-
erwise the vehicle height may
change due to the automatic
leveling function, and you may
catch part of your body in the
vehicle.
■To avoid accident or injury
●Do not exceed the TWR,
unbraked TWR, GCWR, GVWR
or GAWR.
●If the gross trailer weight is over
2000 lb. (900 kg), a sway con-
trol device with sufficient capac-
ity is required.
●If the gross trailer weight is over
5000 lb. (2200 kg), a weight dis-
tributing hitch with sufficient
capacity is required.
●Adjust the tongue weight within
the appropriate range. Place
heavier loads as close to the
trailer axle as possible.

Your vehicle will handle differ-
ently when towing a trailer. To
help avoid an accident, death or
serious injury, keep the following
in mind when towing:
 Speed limits for towing a
trailer vary by state or prov-
ince. Do not exceed the
posted towing speed limit.
 Toyota recommends that the
vehicle-trailer speed limit is 65
mph (104 km/h) on a flat,
straight, dry road. Do not
exceed this limit, the posted
towing speed limit or the
speed limit for your trailer as
set forth in your trailer owner’s
manual, whichever is lowest.
Instability of the towing vehi-
cle-trailer combination (trailer
sway) increases as speed
increases. Exceeding speed
limits may cause loss of con-
trol.
 Before starting out, check the
trailer lights, tires and the
vehicle-trailer connections.
Recheck after driving a short
distance.

engine coolant temperature
gauge indicates overheating,
immediately turn off the air
conditioning (if in use), pull
your vehicle off the road and
stop in a safe spot. (P.543)
 Always place wheel blocks
under both the vehicle’s and
the trailer’s wheels when
parking. Apply the parking
brake firmly, and put the
transmission in P. Avoid park-
ing on a slope, but if unavoid-
able, do so only after
performing the following:
1 Apply the brakes and keep
them applied.
2 Have someone place wheel
blocks under both the vehi-
cle’s and trailer’s wheels.
3 When the wheel blocks are in
place, release the brakes
slowly until the blocks absorb
the load.
4 Apply the parking brake
firmly.
5 Shift into P and turn off the
hybrid system.
 When restarting after parking
on a slope:
1 With the transmission in P,
start the hybrid system. Be
sure to keep the brake pedal
pressed.
2 Shift into a forward gear. If
reversing, shift into R. 3
If the parking brake is in man-
ual mode, release the park-
ing brake. ( P.222)
4 Release the brake pedal, and
slowly pull or back away from
the wheel blocks. Stop and
apply the brakes.
5 Have someone retrieve the
blocks.
■Break-in schedule
If your vehicle is new or equipped
with any new power train compo-
nents (such as an engine, transmis-
sion, transfer [4WD models], rear
differential or wheel bearing), Toyota
recommends that y ou do not tow a
trailer until the vehicle has been
driven for over 500 miles (800 km).
After the vehicle has been driven for
over 500 miles (800 km), you can
start towing. However, for the next
500 miles (800 km), drive the vehi-
cle at a speed of less than 50 mph
(80 km/h) when towing a trailer, and
avoid full throttle acceleration.
■Maintenance
●If you tow a trailer, your vehicle
will require more fr equent mainte-
nance due to the additional load.
(See “Owner’s Warranty Informa-
tion Booklet” or “Scheduled Main-
tenance Guide” / “Owner’s Manual
Supplement”.)
●Retighten the fixing bolts of the
towing ball and bracket after
approximately 600 miles (1000
km) of tra iler towing.
■If trailer sway occurs
One or more factors (crosswinds,
passing vehicles, rough roads, etc.)
can adversely affect handling of
your vehicle and trailer, causing
instability.

■If a warning message is displayed on the multi-information disp lay
A system may be tempor arily unavailable or there may be a malfu nction in
the system.
●In the following situations, perform the actions specified in t he table. When
the normal operating conditions are detected, the message will disappear
and the system will be come operational.
If the message does not disapp ear, contact your Toyota dealer.
SituationActions
When the area around a camera is
covered with dirt, moisture (fogged
up, covered with condensation, ice,
etc.), or other foreign matterUsing the wiper and A/C function,
remove the dirt and other attached
matter. ( P.407)
When the temperature around the
front camera is outside of the opera-
tional range, such as when the vehi-
cle is in the sun or in an extremely
cold environment
If the front camera is hot, such as
after the vehicle had been parked in
the sun, use the air conditioning sys-
tem to decrease the temperature
around the front camera.
If a sunshade was used when the
vehicle was parked, depending on its
type, the sunlight reflected from the
surface of the sunshade may cause
the temperature of the front camera
to become excessively high.
If the front camera is cold, such after
the vehicle is parked in an extremely
cold environment, use the air condi-
tioning system to increase the tem-
perature around the front camera.
The area in front o f the front camera
is obstructed, such as when the
hood is open or a sticker is attached
to the part of the win dshield in front
of the front camera.
Close the hood, rem ove the sticker,
etc., to clear the obstruction.
When “Pre-Collisio n System Radar
In Self Calibration Unavailable See
Owner’s Manual” is displayed.Check whether there is attached
materials on the radar sensor and
radar sensor cover, and if there is,
remove it.

■The system can be operated
when
●The power switch is in ON.
●Intuitive parking assist function is
on.
●The vehicle speed is less than
about 6 mph (10 km/h).
●A shift position other than P is
selected.
■If “Parking Assist Unavailable
Clean Parking Assist Sensor” is
displayed on the multi-informa-
tion display
A sensor may be covered with water
drops, ice, snow, d irt, etc. Remove
the water drops, ice, snow, dirt, etc.,
from the sensor to return the system
to normal.
Also, due to ice forming on a sensor
at low temperatures, a warning
message may be displayed or the
sensor may not be able to detect an
object. Once the ice melts, the sys-
tem will return to normal.
If a warning message is displayed
even if the sensor is clean, there
may be a sensor malfunction. Have
the vehicle inspected by your Toyota
dealer.
■If “Parking Assist Unavailable”
is displayed on the multi-infor-
mation display
Water may be continuously flowing
over the sensor surface, such as in
a heavy rain. When the system
determines that it is normal, the sys-
tem will return to normal.
■Sensor detection information
●The sensor’s detection areas are
limited to the areas around the
vehicle’ front and rear bumpers.
●The following situations may occur
during use.
• Depending on the shape of the object and other factors, the
detection distance may shorten, or
detection may be impossible.
• Detection may be impossible if
static objects draw too close to the
sensor.
• There will be a short delay
between static object detection
and display (warning buzzer
sounds). Even at low speeds,
there is a possibility that the object
will come within 11.9 in. (30 cm)
before the display is shown and
the warning buzzer sounds.
• It might be diffic ult to hear the
buzzer due to the volume of the
audio system or air flow noise of
the air conditioning system.
• It may be diffi cult to hear the
sound of this sys tem due to the
buzzers of other systems.
■Objects which the system may
not be properly detected
The shape of the object may pre-
vent the sensor from detecting it.
Pay particular attent ion to the follow-
ing objects:
WARNING
●When using a high pressure
washer to wash the vehicle, do
not spray the sensors directly,
as doing so may cause a sensor
to malfunction.
●When using steam to clean the
vehicle, do not direct steam too
close to the sensors as doing so
may cause a sens or to malfunc-
tion.

●Wires, fences, ropes, etc.
●Cotton, snow and other materials
that absorb sound waves
●Sharply-angled objects
●Low objects
●Tall objects with upper sections
projecting outwards in the direc-
tion of your vehicle
■Situations in which the system
may not operate properly
Certain vehicle conditions and the
surrounding environment may affect
the ability of a sensor to correctly
detect objects. Particular instances
where this may occur are listed
below.
●There is dirt, snow, water drops or
ice on a sensor. (Cleaning the
sensors will resolve this problem.)
●A sensor is frozen. (Thawing the
area will resolve this problem.)
In especially cold weather, if a
sensor is frozen the sensor dis-
play may be displayed abnormally,
or objects, such as a wall, may not
be detected.
●When a sensor or the area around
a sensor is extremely hot or cold.
●On an extremely bumpy road, on
an incline, on gravel, or on grass.
●When vehicle horns, vehicle
detectors, motorcycle engines, air
brakes of large vehicles, the clear-
ance sonar of other vehicles or
other devices which produce ultra-
sonic waves are near the vehicle
●A sensor is coated with a sheet of
spray or heavy rain.
●If objects draw too close to the sensor.
●When a pedestrian is wearing
clothing that does not reflect ultra-
sonic waves (ex. skirts with gath-
ers or frills).
●When objects that are not perpen-
dicular to the ground, not perpen-
dicular to the vehicle traveling
direction, uneven, or waving are in
the detection range.
●Strong wind is blowing
●When driving in inclement weather
such as fog, snow or a sandstorm
●When an object that cannot be
detected is between the vehicle
and a detected object
●If an object such as a vehicle,
motorcycle, bicycle or pedestrian
cuts in front of the
vehicle or runs
out from the side of the vehicle
●If the orientation of a sensor has
been changed due to a collision or
other impact
●When equipment that may
obstruct a sensor is installed, such
as a towing eyelet, bumper pro-
tector (an additional trim strip,
etc.), bicycle car rier, or snow plow
●If the front of the v ehicle is raised
or lowered due to the carried load
●If the vehicle cannot be driven in a
stable manner, such as when the
vehicle has been in an accident or
is malfunctioning
●When a tire chains, compact
spare tire or an emergency tire
puncture repair kit is used
●When the back door is opened
■Situations in which the system
may operate even if there is no
