■Operational conditions
The pre-collision system is enabled and the system determines that the pos-
sibility of a frontal collision wi th a vehicle or pedestrian is high.
Each function is operational at the following speeds:
● Pre-collision warning:
• Vehicle speed is between approximately 7 and 110 mph (10 and 180 km/h).
(For detecting a pedestrian, vehicle speed is between approximately 7 and
50 mph [10 and 80 km/h].)
• The relative speed between your vehicle and the vehicle or pedestrian ahead is approximately 7 mph (10 km/h) or more.
● Pre-collision brake assist:
• Vehicle speed is between approximately 19 and 110 mph (30 and 180 km/h).
(For detecting a pedestrian, vehicle speed is between approximately 19 and
50 mph [30 and 80 km/h].)
• The relative speed between your vehicle and the vehicle or pedestrian ahead is approximately 19 mph (30 km/h) or more.
● Pre-collision braking:
• Vehicle speed is between approximately 7 and 110 mph (10 and 180 km/h).
(For detecting a pedestrian, vehicle speed is between approximately 7 and
50 mph [10 and 80 km/h].)
• The relative speed between your vehicle and the vehicle or pedestrian
ahead is approximately 7 mph (10 km/h) or more.
The system may not operate in the following situations:
● If a 12-volt battery terminal has been disconnected and reconnected and
then the vehicle has not been driven for a certain amount of time
● If the shift position is in R
● If VSC is disabled (only the pre-collision warning function will be opera-
tional)
● If the PCS warning light is flashing or illuminated

Driving
●Influence from other sonic waves
• An ultrasonic wave source is nearby, such as the horn or parking assist
system of another vehicle, a vehicle detector, a motorcycle engine or the
air brake of a large vehicle
• Electronic components (such as a backlit license plate (especially fluo- rescent types), fog lights, a fender pole or a wireless antenna) are
installed near the sensors
● Changes in the vehicle
• The vehicle is tilted a large amount
• The height of the vehicle has drastically changed due to the carried load
(the nose tilts up or down)
• The direction of the sensor has deviated due to a collision or other impact
■ Intelligent Clearance Sonar function while the Simple Advanced Parking
Guidance System is operating
→P. 444
■ When removing and installi ng the 12-volt battery
The system needs to be initialized.
The system can be initialized by driving the vehicle straight ahead for 5 sec-
onds or more at a speed of approximately 22 mph (35 km/h) or higher.
■ When “ICS Unavailable” is displayed on the multi-information display
and the ICS OFF indicator flashes
● Ice, snow, dirt, etc., may have adhered to the sensor. If this occurs, remove
the ice, snow, dirt, etc., from the sensor to return the system to normal.
Also, a warning message may be displayed at low temperatures due to ice
forming on the sensor, and the sensor may not detect obstacles. Once the
ice melts, the system will return to normal.
● If this message is shown even after removing dirt from the sensor, or shown
when the sensor was not dirty to begin with, have the vehicle inspected at
your Toyota dealer.
● System initialization may not have been performed after removal and instal-
lation of the 12-volt battery. Perform system initialization.
■ When “ICS Malfunction Visit Your Deal er” is displayed on the multi-infor-
mation display, the ICS OFF indi cator flashes and the buzzer sounds
The system may not be operating properly. Have the vehicle inspected at
your Toyota dealer.

When the Simple Advanced Park ing Guidance System cannot be
operated, or when operation is stopped, canceled, etc., the one of the
following message is displayed on the multi-information display. Take
appropriate action according to the display.
■When it is not possible to operate
Multi-information display messages
MessageSituation/Handling method
The system may be malfunctioning.
→ Turn the power switch off and then start the
hybrid system.
Have the vehicle inspected by your Toyota
dealer if the message is displayed again.
There may be a system failure.
Power steering equipment is temporarily overheat-
ing.
→Turn the power switch off, wait for a little
while, and then start the hybrid system again.
The hybrid system is not operating.
→Start the hybrid system.
Ice, snow, dirt, etc., has adhered to the sensor.
→Remove any ice, snow, dirt, etc.
The sensor is frozen.
→Once the sensor thaws, the system will return
to normal.
The 12-volt battery has been removed and rein-
stalled.
→Drive the vehicle straight ahead for 5 seconds
or more at a speed of approximately 22 mph
(35 km/h) or higher.
The S-APGS switch is operated when the vehicle
speed exceeds 19 mph (30 km/h).
→Operate the switch when the vehicle speed is
approximately 19 mph (30 km/h) or less.
Assist control is started while the steering wheel is
held.
→Rest your hands on the steering wheel with-
out applying any force. Assist control will
start.

NOTICE
■Humidity sensor
● Do not spray the glass cleaner on the sensor or subject it to strong impacts
● Do not stick anything on the sensor
■ To prevent 12-volt battery discharge
Do not leave the air conditioning system on longer than necessary when the
hybrid system is off.
■ Air outlets
The air outlets become hot when used for heating. Therefore, use caution
and adjust the air outlets accordingly.
In order to detect fog on the windshield, a
sensor which monitors the temperature
of the windshield, the surround humidity,
etc. is installed. ( →P. 494)
Follow these points to avoid damaging
the sensor:
● Do not disassemble the sensor

Remote Air Conditioning System
If the Remote Air Conditioning Sy stem is used while the charging
cable is connected to the vehicle, the reduction of charge in the hybrid
battery (traction battery) will be s uppressed to allow you to use elec-
tricity from an external power source.
Charging will be conducted automatically after the Remote Air Condition-
ing System is stopped.
Check the temperature setting of the air conditioning system.
( → P. 488, 499)
The Remote Air Conditioning System will operate in accordance with the
temperature settings of the air conditioning system.
Press and hold “A/C” on the wire-
less remote control to operate the
Remote Air Conditioning System.
The system will shut off if a door is
opened.
The system can be stopped by
pressing “A/C” twice.
The Remote Air Conditioning System uses electrical energy
stored in the hybrid battery (traction battery) and allows the air
conditioning to be operat ed by remote control.

■Operating conditions
The system will only operate if all of the following conditions are met:
●The shift position is in P.
● The power switch is off.
*
●All doors are closed.
● The hood is closed.
*: The Remote Air Conditioning System cannot be used for approximately 3
minutes and a half after the power switch is turned off.
■ Remote Air Conditioning System automatic shut-off
The system will automatically shut off under the following conditions:
● About 10 minutes have passed since operation began
● Any one of the operating conditions is not met
The system may also shut off if the charge level of the hybrid battery (traction
battery) drops to low.
■ Conditions affecting operation
The system may not start in the following situations:
●The charge level of the hybrid battery (traction battery) is low
● The outside temperature is extremely low
● When the hybrid system is cool (for example, after being left for a lon\
g time
in low temperatures)
■ Windshield defogger
When defogging the windshield using the Remote Air Conditioning System,
defogging may be insufficient due to the power being restricted more than
during normal air conditioning operation. Also, the outside of the windshield
may fog up due to the outside temperature, humidity or air conditioning set
temperature.
■ Using the heater via the Remote Air Conditioning System
When the outside heat exchanger becomes frosted over, heating perfor-
mance may decline due to automatically switching to the frost removal op\
era-
tion.

■ Conditions affecting operation
→P. 281
■ When using the Remote Air Conditioning System
A charging message will be displayed on the multi-information display. Differ-
ent messages will be displayed depending on when the Remote Air Condi-
tioning System was started (after charging or during charging).
■ While the Remote Air Conditioning System is operating
●Depending on the operating condition of the Remote Air Conditioning Sys-
tem, the electric fan may spin and an operating noise may be heard. How-
ever, this does not indicate a malfunction.
● The Remote Air Conditioning System may stop operating temporarily if
other features that use electricity (for example, the seat heater, lights, wind-
shield wipers) are in operation or if the charge level of the 12-volt battery
becomes low.
● The headlights, windshield wiper, combination meter, etc. will not operate
while the Remote Air Conditioning System is operating.
