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 will resolve
this problem.)
● The sensor is frozen. (Thawing the area will resolve this problem.)
In especially cold weather, if a sensor is frozen, the screen may 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, motorcycle
engines, air brakes of large vehicles , or other loud noises producing 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 installed.
● There is another vehicle equipped with parking assist sensors in the vicin-
ity.
● Towing eyelets are installed.
● A backlit license plate is installed.
In addition to the examples above, depending on the shape and condition of
obstacles, detection may not be possible, or the detection range 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 vehicle 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 parking assist-
sensors of another vehicle, a vehicle detector, a motorcycle engine 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 any authorized Toyota retailer or Toyota authorized repairer, or any reli-
able repairer.
● When using a high-pressure washer to wash the vehicle, do not spray
water directly on the sensors. The sensors may not function properly if
subjected to an impact from strong water pressure.
● When using steam to wash the vehicle, do not direct steam too close 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 collision.
● A chassis roller, chassis dynamo, free roller or similar equipment is being
used for an inspection, etc.
● The vehicle is being loaded onto a ship, truck or other transport 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 carried load
(the nose tilts up or down).
● A towing eyelet is installed
● When using an automatic car wash

S-IPA (Simple Intelligent Parking Assist
System)
■Function summary
The Simple Intelligent Parking Assist System automatically oper-
ates the steering wheel to provide support when backing into an
area near a target parking spot, and when departing from a parallel
parking spot. (Changing the shift position and speed adjustment
when moving forward or backing up are not performed automati-
cally.)
● The Simple Intelligent Parking Assist 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 Intelligent Parking Assist System provides steering
wheel operation assistance to guide the vehicle toward the
selected intended parking spot. The selected intended parking
spot may not always be reachable, 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 Intelligent Parking Assist System is operating, if
the system detects an obstacle that could result in a collision, the
emergency brakes operate, regardless of whether the Parking Sup-
port Brake function is on or off. ( P. 525)

WARNING
●When backing up or proceeding forward, be sure to directly confirm the
safety of the area to the front or rear, and the area around the vehicle, and
slowly back up or proceed forward while adjusting the vehicle speed by
depressing the brake pedal.
● If it seems the vehicle may make contact with a pedestrian, another vehi-
cle or any other obstacles, stop the vehicle by depressing the brake pedal,
and then press the S-IPA switch ( P. 526) to turn the system off.

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 injury.
● Do not allow children to climb on the luggage cover. Climbing on the lug-
gage cover could result in damage to the luggage cover, possibly causing
death or serious injury to the child.
● Make sure that the rear edge of the cover is laying flat. If the cover is
installed with the rear edge raised, t he view from the rear window may be
obstructed, which could cause an accident.
● Make sure that seat belts are not caught up in the luggage cover. If a seat
belt is caught up in the cover, it may not be able to restrain passengers
properly.
