Sensors used by Toyota
Safety Sense 3.0

3665-5. Using the driving support systems
■Objects which the system may
not properly detect
The shape of the object may pre-
vent the sensor from detecting it.
Pay particular attention to the fol-
lowing objects:
●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
People may not be detected if they
are wearing certain types of cloth-
ing.
■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 abnor-
mally, 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.
●When strong winds are 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 such as a towing
eyelet, transport hook, bumper
protector, bumper trim, bicycle
carrier or snow-removal device
(snow plow) is installed near the
sensor.
●If the front of the vehicle 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 tire chains, a compact
spare tire or an emergency tire
puncture repair kit are used.

■Situations in which the system
may operate even if there is no
possibility of a collision
In some situations, such as the fol-
lowing, the system may operate
even though there is no possibility of
a collision.
●When driving on a narrow road.
●When driving toward a banner,
flag, low-hanging branch or boom
barrier (such as those used at rail-
road crossings, toll gates and
parking lots).
●When there is a rut or hole in the
surface of the road.
●When driving on a metal cover
(grating), such as those used for
drainage ditches.
●When driving up or down a steep
slope.
●If a sensor is hit by a large amount
of water, such as when driving on
a flooded road.
●There is dirt, snow, water drops or
ice on a sensor. (Cleaning the
sensors will resolve this problem.)
●A sensor is coated with a sheet of
spray or heavy rain.
●When driving in inclement weather
such as fog, snow or a sandstorm.
●When strong winds are blowing.
●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.
●If the front of the vehicle is raised
or lowered due to the carried load.
●If the orientation of a sensor has
been changed due to a collision or
other impact.
●The vehicle is approaching a tall
or curved curb.
●Driving close to columns (H-
shaped steel beams, etc.) in multi-
story parking garages, construc-
tion sites, etc.
●If the vehicle cannot be driven in a
stable manner, such as when the
vehicle has been in an accident or
is malfunctioning.
●On an extremely bumpy road, on
an incline, on gravel, or on grass.
●When tire chains, a compact
spare tire or an emergency tire
puncture repair kit are used.

tions. Failing to do so may result
in the vehicle being unable to be
driven safely and possibly cause
an accident.
●Do not use this system in situa-
tions such as the following:
• When in areas other than com- mon parking spaces
• When the surface of the parking space is sand or gravel and is
not clearly defined with parking
space lines
• When the parking space is not level, such as when on a slope
or has differences in height
• Mechanical parking system
• Parking lot with a device which raises to contact the bottom of
the vehicle
• When the road surface is fro- zen, slick, or covered with snow
• When it is extremely hot and the asphalt is melting
• When there are objects around the vehicle
• When there is an object between your vehicle and the
target parking spot or within the
target parking spot (within the
displayed blue box)
• When there is a gutter between your vehicle and the target park-
ing space or within the target
parking spot (within the dis-
played blue box)
• When there is a hole or gutter in the exit direction
• When in high pedestrian or vehicle traffic areas
• When the parking space is in a location that is difficult to park in
(too narrow for your vehicle,
etc.)
• When images are unclear due to dirt or snow attached to the
camera lens, light being shined
into the camera or shadows
• When tire chains or a compact spare tire is installed to the vehi-
cle
• When the doors or back door are not completely closed
• When an arm is held outside of a window
• In inclement weather such as heavy rain or snow
●Make sure to use only standard
sized tires, such as those that
were installed to the vehicle
when it was shipped from the
factory. Otherwise, Advanced
Park may not operate properly.
Also, when the tires have been
replaced, the displayed position
of the lines or box displayed on
the screen may become incor-
rect. When replacing the tires,
contact your Toyota dealer.
●In situations such as the follow-
ing, it may not be possible for
the system to provide assis-
tance to a registered parking
spot:
• When the tires are extremely worn or the tire inflation pres-
sure is low
• When carrying a heavy load
• When the vehicle is tilted due to the carried load

Maintenance and care
Do not forget to check the spare.
■Effects of incorrect tire inflation
pressure
Driving with incorrec t tire inflation
pressure may result in the following:
●Reduced fuel economy
●Reduced driving comfort and poor
handling
●Reduced tire life due to wear
●Reduced safety
●Damage to the drive train
If a tire needs frequent inflating,
have it checked by your Toyota
dealer.
■Instructions for checking tire
inflation pressure
When checking tire inflation pres-
sure, observe the following:
●Check only when the tires are
cold.
If your vehicle has been parked
for at least 3 hours or has not
been driven for more than 1 mile
or 1.5 km, you will get an accurate
cold tire inflation pressure reading.
●Always use a tire pressure gauge.
It is difficult to judge if a tire is
properly inflated based only on its
appearance.
●It is normal for the tire inflation
pressure to be higher after driving
as heat is generated in the tire. Do
not reduce tire inflation pressure
after driving.
●Never exceed the vehicle capacity
weight. Passengers and luggage
weight should be placed so that
the vehicle is balanced.
WARNING
■Proper inflation is critical to
save tire performance
Keep your tires properly inflated.
If the tires are not properly
inflated, the following conditions
may occur which could lead to an
accident resulting in death or seri-
ous injury:
●Excessive wear
●Uneven wear
●Poor handling
●Possibility of blow outs resulting
from overheated tires
●Air leaking from between tire
and wheel
●Wheel deformation and/or tire
damage
●Greater possibility of tire dam-
age while driving (due to road
hazards, expansion joints,
sharp edges in the road, etc.)
NOTICE
■When inspecting and adjust-
ing tire inflation pressure
Be sure to put the tire valve caps
back on.
If a valve cap is not installed, dirt
or moisture may get into the valve
and cause an air leak, resulting in
decreased tire inflation pressure.

5648-2. Steps to take in an emergency
■The tire pressure warning light
may come on due to natural
causes
The tire pressure warning light may
come on due to natural causes such
as natural air leaks and tire inflation
pressure changes caused by tem-
perature. In this case, adjusting the
tire inflation pressure will turn off the
warning light (after a few minutes).
■Conditions that the tire pres-
sure warning system may not
function properly
 P.517
WARNING
■If a warning light comes on or
a warning buzzer sounds
when a warning message is
shown on the multi-informa-
tion display
*
Check and follow the message
shown on the multi-information
display.
Failure to do so may result in
death or serious injury.
*: Warning lights illuminate in red
or yellow and the warning
buzzer beeps once or sounds
continuously.
■When the electric power
steering system warning light
comes on
When the light comes on yellow,
the assist to the power steering is
restricted. When the light comes
on red, the assist to the power
steering is lost and handling oper-
ations of the steering wheel
become extremely heavy.
If the steering wheel becomes
heavier than usual when operat-
ing, hold firmly and operate using
more force than usual.
■If the tire pressure warning
light comes on
Be sure to observe the following
precautions. Failure to do so
could cause a loss of vehicle con-
trol and result in death or serious
injury.
●Stop your vehicle in a safe
place as soon as possible.
Adjust the tire inflation pressure
immediately.
●If the tire pressure warning light
comes on even after tire infla-
tion pressure adjustment, it is
probable that you have a flat
tire. Check the tires. If a tire is
flat, repair the flat tire by using
emergency tire puncture repair
kit.
●Avoid abrupt maneuvering and
braking. If the vehicle tires dete-
riorate, you could lose control of
the steering wheel or the
brakes.
■If a blowout or sudden air
leakage should occur
The tire pressure warning system
may not activate immediately.
■Maintenance of the tires
Each tire, includ ing the spare (if
provided), should be checked
monthly when cold and inflated to
the inflation pressure recom-
mended by the vehicle manufac-
turer on the vehicle placard or tire
inflation pressure label (tire and
load information label). (If your
vehicle has tires of a different size
than the size indicated on the
vehicle placard or tire inflation
pressure label [tire and load infor-
mation label], you should deter-
mine the proper tire inflation
pressure for those tires.)

5748-2. Steps to take in an emergency
Stop the vehicle in a safe
place on a hard, flat surface.
 Set the parking brake.
 Shift the shift lever to P.
 Stop the hybrid system.
 Turn on the emergency flash-
ers. ( P.546)
 For vehicles with power back
door: Turn off the power back
door system. ( P.195)
 Check the degree of the tire
damage.
A tire should only be repaired
with the emergency tire punc-
ture repair kit if the damage is
caused by a nail or screw pass-
ing through the tire tread.
• Do not remove the nail or screw from the tire. Removing
the object may widen the
opening and prevent emer-
gency repair with the repair
kit.
• To avoid sealant leakage, move the vehicle until the
area of the puncture, if
known, is positioned at the
top of the tire.
If you have a flat tire
Your vehicle is not
equipped with a spare tire,
but instead is equipped with
an emergency tire puncture
repair kit.
A puncture caused by a nail
or screw passing through
the tire tread can be
repaired temporarily using
the emergency tire puncture
repair kit. (The kit contains a
bottle of sealant. The seal-
ant can be used only once
to temporarily repair one
tire without removing the
nail or screw from the tire.)
Depending on the damage
condition of the flat tire, it
may not be able to repaired
with the emergency tire
puncture repair kit.
( P.575)
After temporarily repairing
the tire with the kit, have the
tire repaired or replaced by
your Toyota dealer.
WARNING
■If you have a flat tire
Do not continue driving with a flat
tire.
Driving even a short distance with
a flat tire can damage the tire and
the wheel beyond repair, which
could result in an accident.
Driving with a flat tire may cause a
circumferential groove on the side
wall.
In such a case, the tire may
explode when using a repair kit.
Before repairing the vehi-
cle
