WARNING
●Do not use the panoramic view
monitor system in the following
cases:
• On icy or slick road surfaces, or in snow
• When using tire chains or emer- gency tires
• When the front door or the tail- gate is not closed completely
• On roads that are not flat or straight, such as curves or
slopes
• If the suspension has been modified or tires of a size other
than specified are installed
●In low temperatures, the screen
may darken or the image may
become faint. The image could
distort when the vehicle is mov-
ing, or you may become unable
to see the image on the screen.
Be sure to visually check all
around the vehicle both directly
and using the mirrors before
proceeding.
●If the tire sizes are changed, the
position of the guide lines dis-
played on the screen may
change.
●The camera uses a special lens.
The distances between objects
and pedestrians that appear in
the image displayed on the
screen will differ from the actual
distances. ( P.335)
●When an aftermarket part is
installed in the display area of
the screen.
NOTICE
●In panoramic view/moving
view/see-through view, the sys-
tem combines images taken
from the front, back, left and
right side cameras into a single
image. There are limits to the
range and content that can be
displayed. Familiarize yourself
with the characteristics of the
panoramic view monitor system
before using it.
●Image clarity may decline at the
four corners of t he panoramic
view/moving view/see-through
view. However, this is not a mal-
function, as these are the
regions along the border of
each camera image where the
images are combined.
●Depending on lighting condi-
tions near each of the cameras,
bright and dark patches may
appear on the panoramic
view/moving view/see-through
view.
●The panoramic view/moving
view/see-through view display
does not extend higher than the
installation pos ition and image
capture range o f each camera.
●There are blind spots around
the vehicle. Accordingly, there
are regions not displayed in
panoramic view.
●Three-dimensional objects dis-
played in wide fr ont view, rear
view or side view may not be
displayed in panoramic
view/moving view/see-through
view.

Owners Manual_USA_M0C052_enbe displayed, have your vehicle
inspected by your Toyota dealer as
soon as possible.
■When the indicator turns on
Indicates a malfunction in the air
suspension system.
Have the vehicle inspected by your
Toyota dealer immediately. ( P.87,
508)
WARNING
■The electronically modulated
air suspension must be
turned off in the following cir-
cumstances:
Otherwise, the automatic leveling
function may cause the vehicle’s
height to change, and you may
catch part of yo ur body in the
vehicle, resulting in an unex-
pected accident or injury:
●When driving through water
such as shallow streams (Put
the vehicle height in “HI” mode
and turn off the electronically
modulated air suspension. Drive
at 18 mph [30 km/h] or slower.)
●When jacking up the vehicle,
installing tire chains or tying the
vehicle with chains/wires for
transportation via flat bed truck
(Turn the system to the manual
mode and stop the hybrid sys-
tem.)
●When the vehicle must be
towed (Put the vehicle height in
“N” mode and turn the system to
the manual mode.)
●When the vehicle gets stuck
(Turn the system to the manual
mode.)
●When disconnecting a trailer
(Put the vehicle height in “N”
mode and turn the system to the
manual mode.)
■Selecting the correct height
mode
Observe the following precautions
to prevent accidents or injury.
Failure to do so may cause dam-
age to parts of the vehicle, as well
as dangerous handling character-
istics, which may lead to fatal or
injury accidents.
●Before you lower the vehicle’s
height, check under the vehicle
to make sure that no one is
there.
●“HI” mode should only be used
when driving on rough roads, for
example when driving off-road.
Because the vehicle’s center of
gravity will become higher when
in the mode, the vehicle may
become unstable when turning
abruptly, resulting in an acci-
dent.
●Do not select “HI” mode when
you load cargo on the roof lug-
gage carrier.
Because the vehicle’s center of
gravity will become higher when
in the mode, the vehicle may
become unstable when turning
abruptly, resulting in an acci-
dent.
NOTICE
■Be careful in any place where
overhead space is limited.
When changing to a higher mode
or after unloading, the vehicle
height will rise. This may cause
damage to the vehicle.
■Do not select “LO” mode
when driving on bumpy
roads.
If the underbody of the vehicle
touches a rugged road surface,
the vehicle ma y be damaged.

WARNING
■Replacing tires
Make sure that all tires are of the
specified size, brand, tread pat-
tern and total load capacity. In
addition, make sure that the tires
are inflated to the recommended
tire inflation pressure level.
The ABS, TRAC, Trailer Sway
Control and VSC systems will not
function correctly if different tires
are installed on the vehicle.
Contact your Toyota dealer for fur-
ther information when replacing
tires or wheels.
■Handling of tires and the sus-
pension
Using tires with any kind of prob-
lem or modifying the suspension
will affect the driving assist sys-
tems, and may cause a system to
malfunction.
■Trailer Sway Control precau-
tion
The Trailer Sway Control system
is not able to reduce trailer sway
in all situations . Depending on
many factors such as the condi-
tions of the vehicle, trailer, road
surface and driving environment,
the Trailer Sway Control system
may not be effec tive. Refer to
your trailer owner’s manual for
information on how to tow your
trailer properly.
■If trailer sway occurs
Observe the following precau-
tions.
Failing to do so may cause death
or serious 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.
Do not increase speed. Do not
apply vehicle brakes.
If you make no extreme correction
with the steering or brakes, your
vehicle and traile r should stabi-
lize. ( P.181)
■Secondary Collision Brake
Do not rely solely upon the Sec-
ondary Collision Brake. This sys-
tem is designed to help reduce
the possibility of further damage
due to a secondary collision, how-
ever, that effect changes accord-
ing to various conditions. Overly
relying on the system may result
in death or serious injury.

3904-6. Driving tips
Owners Manual_USA_M0C052_en
overuse of the accelerator
pedal. Doing so can help control
excessive gasoline consump-
tion.
Control and maintain the vehicle
at a constant speed. Before
stopping at a toll booth or simi-
lar, allow plenty of time to
release the accelerator and gen-
tly apply the brakes. A greater
amount of electrical energy can
be regenerated when slowing
down.
Use the air conditioning only
when necessary. Doing so can
help reduce excessive gasoline
consumption.
In summer: When the ambient
temperature is high, use the
recirculated air mode. Doing so
will help to reduce the burden on
the air conditioning system and
reduce fuel consumption as
well.
In winter: Because the gasoline
engine will not automatically cut
out until it and the interior of the
vehicle are warm, it will con-
sume fuel. Also, fuel consump-
tion can be improved by
avoiding overuse of the heater.Make sure to check the tire infla-
tion pressure frequently.
Improper tire inflation pressure
can cause poor fuel economy.
Also, as snow tires can cause
large amounts of friction, their
use on dry roads can lead to
poor fuel economy. Use tires
that are appropriate for the sea-
son.
Carrying heavy luggage will lead
to poor fuel economy. Avoid car-
rying unnecessary luggage.
Installing a large roof rack will
also cause poor fuel economy.
Since the gasoline engine starts
up and cuts out automatically
when cold, warming up the
engine is unnecessary. More-
over, frequently driving short
distances will cause the engine
to repeatedly warm up, which
can lead to excess fuel con-
sumption.

Owners Manual_USA_M0C052_en
Check if the treadwear indica-
tors are showing on the tires.
Also check the tires for uneven
wear, such as excessive wear
on one side of the tread.
Check the spare tire condition
and pressure if not rotated.
New tread
Worn tread
Treadwear indicator
The location of treadwear indicators is shown by a “TWI” or “ ” mark,
etc., molded into the sidewall of
each tire.
Replace the tires if the treadwear
indicators are s
howing on a tire.
■When to replace your vehicle’s
tires
Tires should be replaced if:
●The treadwear indicators are
showing on a tire.
●You have tire damage such as
cuts, splits, cracks deep enough
to expose the fabric, and bulges
indicating internal damage
●A tire goes flat repeatedly or can-
not be properly repaired due to the
size or location of a cut or other
damage
If you are not sure, consult with your
Toyota dealer.
■Tire life
Any tire over 6 years old must be
checked by a qualified technician
even if it has seldom or never been
used, or damage is not obvious.
■Maximum load of tire
Check that the n umber given by
dividing the maximum load by 1.10
of the replacement tire is greater
than 1/2 of the Gross Axle Weight
Ratings (GAWR) of either the front
axle or the rear axle, whichever is
greater.
For the GAWR, see the Certification
Label.
For the maximum load of the tire,
see the load limit at maximum cold
tire inflation pressure mentioned on
the sidewall of the tire. ( P.551)
Tires
Replace or rotate tires in
accordance with mainte-
nance schedules and tread-
wear.

4686-3. Do-it-yourself maintenance
Owners Manual_USA_M0C052_en
Rotate the tires in the order
shown.
Front
To equalize tire wear and extend
tire life, Toyota recommends that
tire rotation is c arried out at the
same interval as tire inspection.
Do not fail to initialize the tire pres-
sure warning system after tire rota-
tion.
Your vehicle is equipped with a
tire pressure warning system
that uses tire pressure warning
valves and transmitters to detect low tire inflation pressure before
serious problems arise.
The tire pressure warning sys-
tem of this vehicle adopts a 2-
type warning system

When “Adjust Pressure” is
displayed (Normal Warning)
The tire pressure warning light
comes on and a buzzer sounds
when the tire inflation pressure
becomes low due to natural air
leakage or outside temperature.
(Ways of coping: P.509, 547)
 When “Immediately Check
tire when Safe” is displayed
(Emergency Warning)
The tire pressure warning light
comes on and a buzzer sounds
when the tire inflation pressure
becomes low suddenly due to a
blowout. (Ways of coping: P.515)
However, the system may not be
able to detect sudden tire ruptures
(bursting, etc.).
The tire pressure detected by the
tire pressure warning system can
be displayed on the multi-informa-
tion display.
The unit can be changed.
NOTICE
■Driving on rough roads
Take particular care when driving
on roads with loose surfaces or
potholes.
These conditions may cause
losses in tire inf lation pressure,
reducing the cushio ning ability of
the tires. In addit ion, driving on
rough roads may cause damage
to the tires themselves, as well as
the vehicle’s wheels and body.
