◆Air conditioning
●Turn the “A/C” switch (
*1 • *2) off when it is
not needed. Doing so can help reduce excessive electricity and
fuel consumption.
In summer: When the ambient temperature is high, use the recir-
culated air mode. Doing so will help to reduce the burden on th e
air conditioning system and reduc e electricity and fuel consump-
tion as well.
In winter: Avoid excessive and unnecessary use of the heater.
Usage of the heated steering w heel (if equipped) and seat heat-
ers is effective. ( P. 5 2 2 )
● Using the Remote Air Conditioning System ( P. 518) while the
charging cable is connected to the vehicle can reduce electrici ty
consumption immediately after st arting off by operating air condi-
tioning mainly using electricity from an external power source.
● When setting the timer, selecting the start time setting mode a nd
setting “Climate Prep” to “On” c an reduce electricity consumption
immediately after starting off by operating air conditioning be fore
charging is completed. ( P. 154)
*1: Vehicles with 7-inch display
*2: Vehicles with 11.6-inch display
◆Checking tire inflation pressure
Make sure to check the tire inflation pressure frequently. If t here is
improper tire inflation pressur e in the tires, the EV driving range will
become shorter, and fuel consumption when in HV mode will
increase.
Also, as snow tires can cause large amounts of friction, their use on
dry roads can lead t o increased fuel and electricity consumptio n.
◆Luggage
Carrying heavy luggage will lead to poor fuel economy. Avoid carry-
ing unnecessary luggage. Installing a large roof rack will also cause
poor fuel economy.
◆Warming up before driving
Since the gasoline engine starts up and cuts out automatically,
warming up is not necessary.

*1: These lights turn on when the power switch is turned to ON mode to indi-
cate that a system check is being performed. They will turn off after the
hybrid system is on, or after a few seconds. There may be a malfunction in
a system if a light does not come on, or turn off. Have the veh icle
inspected by your Toyota dealer.

• The vehicle is wobbling.
• The vehicle is being driven at extremely high speeds.
• When driving on a hill
• If the radar sensor or camera sensor is misaligned
● In some situations such as the following, sufficient braking fo rce may not be
obtained, preventing the system from performing properly:
• If the braking functions cannot operate to their full extent, such as when
the brake parts are extremely cold, extremely hot, or wet
• If the vehicle is not properly maintained (brakes or tires are excessively
worn, improper tire inflation pressure, etc.)
• When the vehicle is being driven on a gravel road or other sli ppery sur-
face
● Some pedestrians such as the following may not be detected by t he radar
sensor and camera sensor, preventing the system from operating properly:
• Pedestrians shorter than approximately 3.2 ft. (1 m) or taller than approx-
imately 6.5 ft. (2 m)
• Pedestrians wearing oversized clothing (a rain coat, long skir t, etc.), mak-
ing their silhouette obscure
• Pedestrians who are carrying large baggage, holding an umbrella, etc., hiding part of their body

brightness as their surroundings
• Pedestrians near walls, fences, guardrails, or large objects
• Pedestrians who are on a metal object (manhole cover, steel plate, etc.) on the road
• Pedestrians who are walking fast
• Pedestrians who are changing speed abruptly

■Conditions in which functions may not operate properly
In the following situations, the camera sensor may not detect w hite (yellow)
lines and various functions may not operate normally.
● There are shadows on the road that run parallel with, or cover, the white
(yellow) lines.
● The vehicle is driven in an area without white (yellow) lines, such as in front
of a tollgate or checkpoint, or at an intersection, etc.
● The white (yellow) lines are cracked, “Botts’ dots”, “Raised pa vement
marker” or stones are present.
● The white (yellow) lines cannot be seen or are difficult to see due to sand,
etc.
● The vehicle is driven on a road surface that is wet due to rain , puddles, etc.
● The traffic lines are yellow (which may be more difficult to re cognize than
lines that are white).
● The white (yellow) lines cross over a curb, etc.
● The vehicle is driven on a bright surface, such as concrete.
● The vehicle is driven on a surface that is bright due to reflec ted light, etc.
● The vehicle is driven in an area where the brightness changes s uddenly,
such as at the entrances and exits of tunnels, etc.

NOTICE
■Preventing sensor malfunctions
● If the area around a sensor is subjected to an impact, equipment may not
operate properly due to a sensor malfunction. Have the vehicle inspected
at your Toyota dealer.
● When using a high-pressure washer to wash the vehicle, do not s pray
water directly on the sensors. The sensors may not function pro perly if
subjected to an impact from strong water pressure.
● When using steam to wash the vehicle, do not direct steam too c lose to
the sensors. The sensors may not function properly if subjected to steam.
■ Preventing unnecessary operation
In the following situations, turn the Intelligent Clearance Son ar function off.
The system may operate even though there is no possibility of a collision.
● A chassis roller, chassis dynamo, free roller or similar equipm ent is being
used for an inspection, etc.
● The vehicle is being loaded onto a ship, truck or other transpo rt vessel
● The suspension has been lowered or tires that have a different size than

WARNING
●Do not use the system in the following situations, as the syste m may be
unable to correctly assist you in reaching the target parking s pot and may
lead to an unexpected accident.
• In an area that is not a parking lot
• A parking lot that is not paved and has no parking space lines, such as a sand or gravel parking lot
• A parking lot that has a slope or undulations in the road
• A frozen, snow-covered or slippery road
• The asphalt is melting due to hot weather
• There is an obstacle between the vehicle and the target parking spot
• Using tire chains
● Do not use tire other than that provided by the manufacturer. The system
may not operate properly. When replacing tires, contact your Toyota
dealer.
● The system may not be able position the vehicle in the set location in the
following situations.
• The tires are extremely worn or the tire pressure is low
• The vehicle is carrying very heavy load
• The vehicle is tilted due to having luggage, etc. located on one side of
the vehicle
• There are road heaters installed in the parking lot to prevent the road
surface from freezing.
In any other situations when the set position and vehicle posit ion greatly
differ, have the vehicle inspected by your Toyota dealer.
● Make sure to observe the following precautions regarding the exit parallel
parking assist mode.
Exit parallel parking assist mode is a function used when depar ting from a
parallel parking spot. However, this function may not be usable if obsta-
cles or people are detected in front of the vehicle. Only use t his function
when departing from a parallel parking spot. In the event that the steering
control operates, either turn the system off using the S-APGS s witch or
operate the steering wheel to stop the control.
● If exit parallel parking assist mode is mistakenly used in the following situ-
ations, the vehicle may make contact with an obstacle.
The departure function is operated in a direction where an obst acle is
present, but the obstacle is not detected by the side sensors ( situations
such as when the vehicle is directly beside a pole).
