PRIUS +_OM_OM47B24E_(EE)
When your vehicle is too close to a vehicle ahead, and sufficient auto-
matic deceleration via the cruise control is not possible, the display
will flash and the buzzer will sound to alert the driver. An example of
this would be if another driver cuts in front of you while you are follow-
ing a vehicle. Apply the brakes to ensure an appropriate vehicle-to-
vehicle distance.
■Warnings may not occur when
In the following instances, there is a possibility that the warnings will
not occur:
●When the speed of the vehicle ahead matches or exceeds your
vehicle speed
● When the vehicle ahead is traveling at an extremely slow speed
● Immediately after the cruise control speed was set
● At the instant the accelerator is applied

PCS (Pre-Crash Safety system)∗
◆Pre-crash warning
When a high possibility of a
frontal collision is detected, a
buzzer sounds and a message
is shown on the multi-informa-
tion display to urge the driver to
take evasive action.
◆Pre-crash brake assist
When there is a high possibility of a frontal collision, the system
applies greater braking force in relation to how strongly the brake
pedal is depressed.
◆Pre-crash braking
When there is a high possibility of a frontal collision, the system
warns the driver using a warning display and buzzer. If the system
determines that a collision is unavoidable, the brakes are automati-
cally applied to reduce the collision speed.
∗: If equipped
When the radar sensor detects possibility of a frontal collision,
brakes are automatically engaged to lessen impact as well as
vehicle damage.The alert timing for the pre-crash safety system can be changed or
turned ON/OFF, as necessary, by operating the switch. ( →P. 263)

Situations in which the pre-crash safety system does not function prop-
erly
The system may not function effectively in situations such as the following:
● On roads with sharp bends or uneven surfaces
● If a vehicle suddenly moves in front of your vehicle, such as at an intersec-
tion
● If a vehicle suddenly cuts in front of your vehicle, such as when overtaking
● In inclement weather such as heavy rain, fog, snow or sand storms
● When your vehicle is skidding with the VSC system off
● When an extreme change in vehicle height occurs
● When the radar sensor moves off position due to its surrounding area being
subjected to a strong impact
● Due to greatly turning the steering wheel when an obstacle suddenly
appears ahead
● When only part of your vehicle’s front end collides with or contacts, a vehicle
or object in a frontal collision
■ Automatic cancelation of the pre-crash safety system
When a malfunction occurs due to sensor contamination, etc. that results in
the sensors being unable to detect obstacles, the pre-crash safety system will
be automatically disabled. In this case, the system will not activate even if
there is a collision possibility.
■ When there is a malfunction in the system, or if the system is tempo-
rarily unusable
The PCS warning light flashes and a warning message is shown on the multi-
information display. If a warning message is shown on the multi-information
display, read the message and follow the instructions. ( →P. 387, 400)

The air conditioning system begins to operate. Air outlets and fan
speed are automatically adjusted according to the temperature set-
ting.
To switch the air conditioning (cooler/dehumidifier functions) ON or OFF,
press . (ON and OFF are switched between each time the button is
pressed.)
*: When is pressed, the current temperature setting display ( )
will be automatically selected.
Turn to the clockwise to raise the temperature, or counter-
clockwise to lower.

If the fan speed setting or airflow modes are operated, the auto-
matic mode indicator goes off. However, automatic mode for func-
tions other than that operated is maintained.

■Using automatic mode
Fan speed is adjusted automatically according to the temperature 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.
■ After pressing
The selection frame will automatically move to the fan speed display.
■ Fogging up of the windows
●The windows will easily fog up when the humidity in the vehicle is high.
Pressing 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.
■ Outside/recirculated air mode
●When driving on dusty roads such as tunnels or in heavy traffic, set
to the recirculated air mode. This is effective in preventing outside air from
entering the vehicle interior. During c ooling operation, setting the recircu-
lated air mode will also cool t he vehicle interior effectively.
● Outside/recirculated air mode may automatically switch depending on the
temperature setting or the inside temperature.
■ Outside temperature display
In the following situations, the correct out-
side temperature may not be displayed, or
the display may take longer than normal
to change.
●When stopped, or driving at low speeds
(less than 25 km/h [16 mph])
● When the outside temperature has
changed suddenly (at the entrance/exit
of a garage, tunnel, etc.)
