PCS (Pre-Collision System)∗
∗: If equipped
When the radar sensor detects possibility of a frontal collision, the
pre-collision systems such as the brakes and seat belts are automat-
ically engaged to lessen impact as well as vehicle damage.
■Pre-collision seat belts (front seat belts only)
If the pre-collision sensor detects that a collision is unavoidable, the
pre-collision system will retract the seat belt before the collision occurs.
The same will happen if the driver makes an emergency braking or
loses control of the vehicle. (→P. 1 5 8 )
However, when the VSC system is disabled, the system will not oper-
ate in the event of skidding.
■Pre-collision 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-collision braking
When there is a high possibility of a frontal collision, the system warns
the driver using a warning light, warning display and buzzer. If the sys-
tem determines that a collision is unavoidable, the brakes are automat-
ically applied to reduce the collision speed. Pre-collision braking can be
disabled using the pre-collision braking off switch.

Disabling pre-collision braking
Pre-collision braking enabled
Pre-collision braking disabled
The “PCS” warning light will
turn on when pre-collision
braking is disabled.
Radar sensor
The radar sensor detects vehi-
cles or other obstacles on or
near the road ahead and deter-
mines whether a collision is
imminent based on the position,
speed, and heading of the obsta-
cles.

When driving
■Obstacles not detected
The sensor cannot detect plastic obstacles such as traffic cones. There may
also be occasions when the sensor cannot detect pedestrians, animals,
bicycles, motorcycles, trees, or snowdrifts.
■Situations in which the pre-collision system does not function properly
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 vehicle, such as at an intersection
●If a vehicle suddenly cuts in front of 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 axis of the radar is out of adjustment
■Automatic cancelation of the pre-collision system
When a malfunction occurs due to sensor contamination, etc. that results in
the sensors being unable to detect obstacles, the pre-collision 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
Warning lights and/or warning messages will turn on or flash. (→P. 5 3 6 , 5 4 8 )

CAUTION
■When the sensor may not be correctly detecting the vehicle ahead
Apply the brakes as necessary in any of the following situations.
●When water or snow thrown up by the surrounding vehicles hinders the
functioning of the sensor
●When your vehicle is pointing upwards (caused by a heavy load in the lug-
gage compartment etc.)
●Ve h i c l e s t h a t c u t i n s u d d e n l y
●Ve h i c l e s w i t h s m a l l r e a r e n d s ( t r a i l e r s w i t h n o l o a d o n b o a r d e t c . )
●Motorcycles traveling in the same lane
■Handling the radar sensor
Observe the following to ensure the pre-collision system can function effec-
tively:
●Keep the sensor and grille cover clean at all times.
Clean the sensor and grille cover with a soft cloth so you do not mark or
damage them.
●Do not subject the sensor or surrounding area to a strong impact.
If the sensor moves even slightly off position, the system may become
inaccurate or malfunction. If the sensor or surrounding area is subject to a
strong impact, always have the area inspected and adjusted by your Toy-
ota dealer.
●Do not disassemble the sensor.
●Do not attach accessories or stickers to the sensor, grille cover or sur-
rounding area.
●Do not modify or paint the sensor and grille cover.

2-5. Driving information
PRIUS PHV_OM_OM47818U_(U)
■Before driving the vehicle
Perform the following according to the driving conditions:
●Do not try to forcibly open a window or move a wiper that is
frozen. Pour warm water over the frozen area to melt the ice.
Wipe away the water immediately to prevent it from freezing.
●To e n s u r e p r o p e r o p e r a t i o n o f t he climate control system fan,
remove any snow that has accumulated on the air inlet vents
in front of the windshield.
●Check for and remove any excess ice or snow that may have
accumulated on the exterior lights, vehicle’s roof, chassis,
around the tires or on the brakes.
●Remove snow or mud from the bottom of your shoes before
getting in the vehicle.
■When driving the vehicle
Accelerate the vehicle slowly, keep a safe distance between you
and the vehicle ahead, and drive at a reduced speed suitable to
road conditions.
■When parking the vehicle
Park the vehicle and shift the shift position to P and block the
wheel under the vehicle without setting the parking brake. The
parking brake may freeze up, preventing it from being released.
If necessary, block the wheels to prevent inadvertent sliding or
creeping.

■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 brake pedal is not being depressed.
■When leaving the vehicle
●Check that the headlights are switched to either off or “AUTO”.
●Check that the wiper switch is turned off.
●Check that all windows are closed.
■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
●There is only a slight difference between the air conditioning set temper-
ature and the inside temperature.
The system may also shut off if the charge level of the hybrid battery (trac-
tion battery) drops to low. (→P. 6 0 )
■Conditions affecting operation
The system may not start in the following situations:
●The charge level of the hybrid battery (traction battery) is low (→P. 6 0 )
●The air conditioning temperature is set at a high level or outside tempera-
ture is low
●When the hybrid system is cool (for example, after being left for a long
time in low temperatures)
