Prius Plug-in Hybrid_OM_OM47E75E_(EE)
WARNING
ODo not use the system in the following situations, as the system may be
unable to correctly assist you in reaching the target parking s pot and may
lead to an unexpected accident.
• In an area that is not a parking lot
• A parking lot that is not paved and has no parking space lines , such as
a sand or gravel parking lot
• A parking lot that has a slope or undulations in the road
• A frozen, snow-covered or slippery road
• The asphalt is melting due to hot weather
• There is an obstacle between the vehicle and the target parkin g spot
• Using tire chains
O Do not use tire other than that provided by the manufacturer. The system
may not operate properly. When replacing tires, contact any aut horized
Toyota retailer or Toyota authorized repairer, or any reliable repairer.
O The system may not be able position the vehicle in the set location in the
following situations.
• The tires are extremely worn or the tire pressure is low
• The vehicle is carrying very heavy load
• The vehicle is tilted due to having luggage, etc. located on o ne side of
the vehicle
• There are road heaters installed in the parking lot to prevent the road
surface from freezing.
In any other situations when the set position and vehicle posit ion greatly
differ, have the vehicle inspected by any authorized Toyota ret ailer or
Toyota authorized repairer, or any reliable repairer.
O Make sure to observe the following precautions regarding the exit parallel
parking assist mode.
Exit parallel parking assist mode is a function used when depar ting from a
parallel parking spot. However, this function may not be usable if obsta-
cles or people are detected in front of the vehicle. Only use t his function
when departing from a parallel parking spot. In the event that the steering
control operates, either turn the system off using the S-IPA sw itch or oper-
ate the steering wheel to stop the control.
O If exit parallel parking assist mode is mistakenly used in the following situ-
ations, the vehicle may make contact with an obstacle.
The departure function is operated in a direction where an obst acle is
present, but the obstacle is not detected by the side sensors ( situations
such as when the vehicle is directly beside a pole).

Driving
WARNING
OObserve the following precautions, as the sensors may stop functioning
properly which may lead to an accident.
• Do not subject the sensor to strong shocks by hitting it, etc. The sen-
sors may not function properly.
• When using a high-pressure washer to wash the vehicle, do not spray
water directly on the sensors. Equipment may not function prope rly if
subjected to an impact from strong water pressure. If the vehic le
bumper strikes something, equipm ent may not operate properly due to
a sensor malfunction. Have the vehicle inspected at any authori zed
Toyota retailer or Toyota author ized repairer, or any reliable repairer.
O In the following situations, the sensors may not operate normally and may
lead to an accident. Drive carefully.
• Obstacles cannot be detected in the side areas until a scan of the side
areas is completed. ( P. 456)
• Even after the scan of the side areas is completed, obstacles such as
other vehicles, people or animals that approach from the sides cannot
be detected.
• The sensor is frozen (if it thaws, the system returns to norma l).
A warning message may display at particularly low temperatures due to
the sensor freezing and it may not detect parked vehicles.
• The sensor is blocked by someone’s hand.
• The vehicle is tilted a large amount.
• The temperature is extremely hot or cold.
• The vehicle is driven on undulating roads, slopes, gravel road s, in areas
with tall grass, etc.
• An ultrasonic wave source is nearby, such as the horn or senso rs of
another vehicle, a motorcycle engine or the air brake of a larg e vehicle.
• Heavy rain or a water strikes the vehicle.
• The angle of the sensor may be deviated when assist control st arts
even if there is a parked vehicle in the target parking spot. H ave the
vehicle inspected at any authorized Toyota retailer or Toyota a uthorized
repairer, or any reliable repairer.
• Do not install any accessories within the sensor detection ran ge.

Interior features
QChanging settings using the multi-information display
The air conditioning system settings can be changed on the screen
of the multi-information display. (P. 2 4 2 )
QFogging up of the windows
OThe 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.
OIf you turn off, the windows may fog up more easily.
OThe windows may fog up if the recirculated air mode is used.
QWindshield fog detection function
When automatic mode is set, the humidity sensor (P. 534) detects fog on
the windshield and controls the air conditioning system to prevent fog.
QWhen 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 intake mode be
set to outside air mode and the fan speed to any setting except off.
QOutside/recirculated air mode
OSetting to the recirculated air mode temporarily is recommended in prevent-
ing dirty air from entering the vehicle interior and helping to cool the vehicle
when the outside air temperature is high.
OOutside/recirculated air mode may automatically switch depending on the
temperature setting or the inside temperature.
QFresh air intake system while parking
When parking, the system automatically switches to outside air mode to
encourage better air circulation throughout the vehicle, helping to reduce
odors that occur when starting the vehicle.
