3364-5. Using the driving support systems
■Situations in which the Rear Cross Traffic Auto Brake function may not
operate properly
In some situations such as the following, this function may not operate prop-
erly.
● Objects and vehicles which the radar sensors are not designed t o detect
• Stationary objects
• Vehicles which are moving away from your vehicle
• Pedestrians, motorcycles, bicycles, etc.
*
• Objects which are extremely close to a radar sensor
• Vehicles which are approaching from the right or left at the r ear of the
vehicle at a traveling speed of less than approximately 5 mph ( 8 km/h)
• Vehicles which are approaching from the right or left at the r ear of the
vehicle at a traveling speed of more than approximately 15 mph (24 km/h)
*: Depending on conditions, detection of a vehicle and/or object may occur.
● Situations in which the radar sensors may not be able to detect an object
• When a sensor or the area around a sensor is extremely hot or cold
• If the rear bumper is covered with ice, snow, dirt, etc.
• If heavy rain or water strikes the vehicle
• When the detection area of a radar sensor is obstructed by an adjacent
vehicle
• If the vehicle is significantly tilted
• When equipment that may obstruct a sensor is installed, such a s a towing
eyelet, bumper protector (an additional trim strip, etc.), bicy cle carrier, or
snow plow
• If the suspension has been modified or tires of a size other than specified
are installed
• If the front of the vehicle is raised or lowered due to the ca rried load
• If a sticker or an electronic component, such as a backlit license plate
(especially fluorescent type), fog lights, a fender pole or wir eless antenna
is installed near a radar sensor
• If the orientation of a radar sensor has been changed due to a collision or
other impact or removal and installation
• When multiple vehicles are approaching with only a small gap between each vehicle
• When a vehicle is approaching at high speed
● Situations in which the radar sensor may not detect a vehicle
• When a vehicle approaches from the
right or left at the rear of the vehicle
while you are turning while backing
up
• When turning while backing up

Driving
■Handling the radar sensors
P. 298• When backing out of a shallow angle
parking spot
• Vehicles that the sensors cannot detect due to obstructions
• When backing up on a slope with a sharp change in grade
• When a vehicle turns into the detec- tion area

3545-1. Using the air conditioning system and defogger
■Using automatic mode
Fan speed is adjusted automatically according to the temperatur e setting and
the ambient conditions.
Therefore, the fan may stop for a while until warm or cool air is ready to flow
immediately after is pressed.
■ Operation of the air condit ioning system in S-FLOW mode
If the front passenger’s door or a rear door is opened then clo sed, the air con-
ditioning system determines that a passenger is in the vehicle. In this case,
priority for the airflow will be changed from the driver’s seat only to the front
seats only or all seats, respectively. (Depending on the set temperature or
ambient temperature, priority for the airflow may not be given to the driver’s
seat only.)
If a passenger is judged to be in the vehicle, the system will retain the judge-
ment for a certain amount of time after the power switch is tur ned off.
■ Operation of automatic S-FLOW mode
When the system is operating in automatic S-FLOW mode, if a rea r door is
opened and then closed, S-FLOW mode will be disabled. To enable S-FLOW
mode, press
.
■ Changing from manual S-FLOW mode to automatic S-FLOW mode
Press
to disable S-FLOW mode.
Turn the power switch off.
After 60 minutes have elapsed, change the power switch to ON mo de.
■ Fogging up of the windows
●The windows will easily fog up when the humidity in the vehicle is high.
Turning on will dehumidify the air from the outlets and defog the
windshield effectively.
● If you turn off, the windows may fog up more easily.
● The windows may fog up if the recirculated air mode is used.
■ Windshield fog detection function
When automatic mode is set, the humidity sensor (P. 356) detects fog on
the windshield and controls the air conditioning system to prev ent fog.
■ When driving on dusty roads
Close all windows. If dust thrown up by the vehicle is still drawn into the vehi-
cle after closing the windows, it is recommended that the air i ntake mode be
set to outside air mode and the fan speed to any setting except off.1

3565-1. Using the air conditioning system and defogger
■Air conditioning filter
P. 442
■ Customization
Some functions can be customized. ( P. 553)
WARNING
■To prevent the windshield from fogging up
● Do not use during cool air operation in extremely humid weathe r.
The difference between the temperature of the outside air and t hat of the
windshield can cause the outer surface of the windshield to fog up, block-
ing your vision.
■ To prevent burns (vehicles with outside rear view mirror defogg ers)
Do not touch the rear view mirror surfaces when the outside rea r view mirror
defoggers are on.
NOTICE
■ Humidity sensor
■ To prevent 12-volt b attery discharge
Do not leave the air conditioning system on longer than necessa ry when the
hybrid system is stopped.
● Do not place anything on the instrument
panel which may cover the air outlets.
Otherwise, air flow may be obstructed,
preventing the windshield defoggers
from defogging.
In order to detect fog on the windshield, a
sensor which monitors the temperature
of the windshield, the surround humidity,
etc. is installed. ( P. 354)
Follow these points to avoid damaging
the sensor:
● Do not disassemble the sensor
● Do not spray the glass cleaner on the
sensor or subject it to strong impacts
● Do not stick anything on the sensor

4266-3. Do-it-yourself maintenance
◆Registering ID codes
Vehicles without a tire inflation pressure display function
Every tire pressure warning valve and transmitter has a unique ID
code. In addition to the set of tire pressure warning system se nsor
ID codes initially registered to the vehicle, a second set of ID codes
can be registered.
A second set of tire pressure warning system sensor ID codes ca n
be registered at your Toyota dealer. When 2 sets of ID codes ha ve
been registered, either ID code set can be selected.
Vehicles with a tire inflation pressure display function
Every tire pressure warning valve and transmitter has a unique ID
code. When replacing a tire pressure warning valve and transmit ter,
it is necessary to reg ister the ID codes.
The ID codes can be registered on (4.2-inch display) or (7-
inch display) of the multi-information display.
■Changing the available set of ID codes (vehicles without a tire
inflation pressure display function)
When 2 sets of ID codes are reg istered, the corresponding ID code
set for the installed wheels can be selected on (4.2-inch disp lay)
or (7-inch display) of the multi-information display. It is no t nec-
essary to reregister the ID codes each time the wheels are
changed.
For information regarding changing the registered ID codes for an
ID code set, contact your Toyota dealer.
■How to register the ID codes (vehicles with a tire inflation pr es-
sure display function)
Park the vehicle in a safe place, wait for approximately 20 min -
utes, and then start t he hybrid system. (P. 208)
Select (4.2-inch display) or (7-inch display) on the multi-
information display using the meter control switches on the ste er-
ing wheel. ( P. 111, 125)
4.2-inch display: Select “Vehi cle Settings” and then press .
7-inch display: Select and then press and hold .
Select “TPWS” and then press .
