2664-5. Using the driving support systems
PRIUS +_OM_OM47B24E_(EE)■
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)

Driving
PRIUS +_OM_OM47B24E_(EE)
WARNING
■ Limitations of the pre-crash safety system
The driver is solely responsible for safe driving. Always drive safely, taking
care to observe your surroundings.
Do not use the pre-crash safety system instead of normal braking opera-
tions under any circumstances. This system will not prevent collisions or
lessen damage or injuries in all cases. Do not overly rely on this system.
Failure to do so may cause an accident, resulting in death or serious injury.
This system has been designed to help avoid and reduce the impact of col-
lisions. However, the system operates differently depending on the situation
(→ P. 264, 265).
As a result, the same level of performance may not be expected in all
cases. Also, the pre-crash safety brakes may not operate if the driver is
depressing the brake pedal or turning the steering wheel, as the system will
determine such conditions as collision avoidance operations.
■ Handling the radar sensor
Observe the following to ensure the pre-crash safety system can function
effectively.
Otherwise, the system may not function correctly and could result in an
accident.
●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 not work
normally or malfunction. If the sensor or surrounding area is subject to a
strong impact, always have the area inspected and adjusted by any autho-
rized Toyota dealer or repairer, or another duly qualified and equipped pro-
fessional.
● 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.
● If the sensor needs to be replaced, contact any authorized Toyota dealer
or repairer, or another duly qualified and equipped professional.

3126-1. Maintenance and care
PRIUS +_OM_OM47B24E_(EE)
WARNING
■ When washing the vehicle
Do not apply water to the inside of the engine compartment. Doing so may
cause the electrical components etc. to catch fire.
■ When cleaning the windshield (vehic les with rain-sensing windshield
wipers)
● When the upper part of the windshield where the raindrop sensor is
located is touched by hand
● When a wet rag or similar is held close to the raindrop sensor
● If something bumps against the windshield
● If you directly touch the raindrop sensor body or if something bumps into
the raindrop sensor
■ Precautions regarding the exhaust pipe
Exhaust gasses cause the exhaust pipe to become quite hot.
When washing the vehicle, be careful not to touch the pipe until it has
cooled sufficiently, as touching a hot exhaust pipe can cause burns.
Set the wiper switch to off.
If the wiper switch is in “AUTO”, the wip-
ers may operate unexpectedly in the fol-
lowing situations, and may result in
hands being caught or other serious inju-
ries and cause damage to the wiper
blades.

or repairer, or another duly qualified and
equipped professional.
Indicates that the hybrid battery (traction battery)
is low
A buzzer also sounds.
→ When stopping the vehicle for a long
period of time, shift the shift position to P.
The battery cannot be charged with the

put of the hybrid system may temporarily
decrease in order to protect the system. (For
example, when driving up a long steep hill or
driving up a steep hill in reverse.)
A buzzer also sounds.
→ Stop and check. ( →P. 457)
