WARNING
■Sensors
Certain vehicle conditions and the surrounding environment may affect the
ability of the sensor to correctly detect obstacles. Particular instances where
this may occur are listed below.
● There is dirt, snow or ice on the sensor. (Wiping the sensors w ill resolve
this problem.)
● The sensor is frozen. (Thawing the area will resolve this probl em.)
In especially cold weather, if a sensor is frozen, the screen m ay show an
abnormal display, or obstacles may not be detected.
● The sensor is covered in any way.
● In harsh sunlight or intense cold weather
● On an extremely bumpy road, on an incline, on gravel, or on grass
● The vicinity of the vehicle is noisy due to vehicle horns, moto rcycle
engines, air brakes of large vehicles, or other loud noises pro ducing ultra-
sonic waves.
● The sensor is splashed with water or drenched with heavy rain.
● The sensor is drenched with water on a flooded road.
● The vehicle is leaning considerably to one side.
● The vehicle is equipped with a fender pole or wireless antenna.
● The vehicle is approaching a tall or curved curb.
● The area directly under the bumpers is not detected.
● If obstacles draw too close to the sensor.
● The bumper or sensor receives a strong impact.
● A non-genuine Toyota suspension (lowered suspension etc.) is in stalled.
● There is another vehicle equipped with parking assist sensors i n the vicin-
ity.
● Towing eyelets are installed.
● A backlit license plate is installed.
In addition to the examples above, depending on the shape and c ondition of
obstacles, detection may not be possible, or the detection rang e may be
shortened.

■Situations when the system may operate even though there is no possi-
bility of a collision
In the following situations, the system may operate even though there is no
possibility of a collision.
● Environmental influence
• The vehicle is driven toward a banner or flag, a low-hanging branch or a
boom barrier (such as those used at railroad crossings, toll gates and
parking lots).
• There is an obstacle on the shoulder of the road (when the veh icle is
driven in a narrow tunnel, on a narrow bridge or on a narrow road)
• The vehicle is being parallel parked
• There is a rut or hole in the surface of the road
• When the vehicle is driven on a metal cover (grating), such as those used
for drainage ditches
• The vehicle is driven on a steep slope
• The sensor is covered by water on a flooded road
● Influence from the weather
• Ice, snow, dirt, etc., has adhered to the sensor (if removed, the system
returns to normal)
• Heavy rain or water strikes the vehicle
• In severe weather such as fog, snow or a sand storm
● Influence from other sonic waves
• An ultrasonic wave source is nearby, such as the horn or parki ng assist
sensors of another vehicle, a vehicle detector, a motorcycle en gine 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
• The vehicle is driven on a narrow
road
• The vehicle is driven on a gravel road or in an area with tall grass

NOTICE
■Preventing sensor malfunctions
● If the area around a sensor is subjected to an impact, equipment may not
operate properly due to a sensor malfunction. Have the vehicle inspected
at your Toyota dealer.
● When using a high-pressure washer to wash the vehicle, do not s pray
water directly on the sensors. The sensors may not function pro perly if
subjected to an impact from strong water pressure.
● When using steam to wash the vehicle, do not direct steam too c lose to
the sensors. The sensors may not function properly if subjected to steam.
■ Preventing unnecessary operation
In the following situations, turn the Parking Support Brake function off. The
system may operate even though there is no possibility of a col lision.
● A chassis roller, chassis dynamo, free roller or similar equipm ent is being
used for an inspection, etc.
● The vehicle is being loaded onto a ship, truck or other transpo rt vessel
● The suspension has been lowered or tires that have a different size than
the genuine tires are equipped
● The height of the vehicle has drastically changed due to the ca rried load
(the nose tilts up or down).
● A towing eyelet is installed
● When using an automatic car wash

S-APGS (Simple Adva nced Parking Guidance
System)

■Function summary
The Simple Advanced Parking Guidance System automatically
operates the steering wheel to provide support when backing int o
an area near a target parking spot, and when departing from a p ar-
allel parking spot. (Changing the shift position and speed adju st-
ment when moving forward or backing up are not performed
automatically.)
● The Simple Advanced Parking Guidance System does not park
the vehicle automatically. It is a system that provides support
when pulling out of a perpendicular or parallel parking spot.
● The Simple Advanced Parking Guidance System provides steer-
ing wheel operation assistance to guide the vehicle toward the
selected intended parking spot. The selected intended parking
spot may not always be reach able, depending on road and vehi-
cle conditions at the time of parking, and the distance to the
intended parking spot.
■Linking with the Parking Support Brake function
While the Simple Advanced Parking Guidance System is operating,
if the system detects an obstacl e that could result in a collision, the
emergency brakes operate, regardl ess of whether the Parking Sup-
port Brake function is on or off. ( P. 388)

WARNING
●Do not place anything on the luggage cover. In the event of sudden brak-
ing or turning, the item may go flying and strike an occupant. This could
lead to an unexpected accident, resulting in death or serious i njury.
● Do not allow children to climb on the luggage cover. Climbing o n the lug-
gage cover could result in damage to the luggage cover, possibl y causing
death or serious injury to the child.
● Make sure that the rear edge of the cover is laying flat. If th e cover is
installed with the rear edge raised, the view from the rear win dow may be
obstructed, which could cause an accident.
