WARNING
●Do not rely solely upon the Simple Advanced Parking Guidance System.
As with unequipped vehicles, move forward and back up carefully while
directly confirming the safety of your surroundings and the area to the rear
of the vehicle.
● Do not back up while viewing the multi-information display. Backing up
while only viewing the monitor screen may cause a collision or lead to an
accident, as the image displayed on the monitor screen may differ from
actual conditions. Make sure to visually check the surrounding areas and
the area to the rear of the vehicle with and without the mirror while backing
up.
● Drive slowly while adjusting your speed by depressing the brake pedal
when backing up or moving forward.
● 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-APGS switch to turn OFF the system.
● Use the system in a parking lot with a flat surface.
● Observe the following precautions, as the steering wheel automatically
turns during use.
• There is risk of a necktie, scarf, your arm, etc. being caught on the
steering wheel. Please do not allow your upper body to be close to the
steering wheel. Also, do not allow children close to the steering wheel.
• There is a possibility of injury when the steering wheel turns if you have long fingernails.
• In case of an emergency, stop the vehicle by depressing the brake pedal, and then press the S-APGS switch to turn OFF the system.
● Always confirm that there is appropriate space before attempting to park
the vehicle and operate the system.

WARNING
●Do not use the system in the following situations, as the system may be
unable to correctly assist you in reaching the target parking spot 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 parking spot
• Using tire chains or emergency tire
● Do not use tire other than that provided by the manufacturer. The system
may not operate properly. When replacing tires, contact your Toyota
dealer.
● 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 one 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 position greatly
differ, have the vehicle inspected by your Toyota dealer.
● Make sure to observe the following precautions regarding the exit parallel
parking assist mode.
Exit parallel parking assist mode is a function used when departing 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 this function
when departing from a parallel parking spot. In the event that the steering
control operates, either turn the system off using the S-APGS switch or
operate the steering wheel to stop the control.
● 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 obstacle is
present, but the obstacle is not detected by the side sensors (situations
such as when the vehicle is directly beside a pole)

WARNING
●Observe 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 properly if
subjected to an impact from strong water pressure. If the vehicle
bumper strikes something, equipment may not operate properly due to
a sensor malfunction. Have the vehicle inspected at your Toyota dealer.
● 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. 341).
• 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 normal). A warn- ing 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 r oads, slopes, gravel roads, in areas
with tall grass, etc.
• An ultrasonic wave source is nearby, such as the horn or sensors of another vehicle, a motorcycle engine or the air brake of a large vehicle.
• Heavy rain or a water strikes the vehicle.
• The angle of the sensor may be deviated when assist control starts even if there is a parked vehicle next to the target parking spot. Have
the vehicle inspected at your Toyota dealer.
• Do not install any accessories within the sensor detection range.

Rear view monitor system
The rear view image is displayed
when the shift lever is in R and the
power switch is in ON mode.
The rear view monitor system will
be deactivated when the shift lever
is in any position other than R.
The rear view monitor system assists the driver by displaying an
image of the view behind the veh icle with fixed guide lines on
the screen while backing up, for example while parking.
The screen illustrations used in this text are intended as examples,
and may differ from the image that is actually displayed on the
screen.

■Area displayed on screen
The rear view monitor system
displays an image of the view
from the bumper of the rear
area of the vehicle.
The image adjustment proce-
dure for the rear view monitor
system screen is the same as
the procedure for adjusting the
screen. (P. 432)
• The area displayed on the
screen may vary according to
vehicle orientation conditions.
• Objects which are close to either corner of the bumper or under
the bumper cannot be dis-
played.
• The camera uses a special lens. The distance of the image that appears
on the screen differs from the actual distance.
• Items which are located higher than the camera may not be displayed on the monitor.

■Rear view monitor system camera
The camera for the rear view
monitor system is located as
shown in the illustration.
● Using the camera
If dirt or foreign matter (such as water droplets, snow, mud etc.)
is adhering to the camera, it cannot transmit a clear image. In
this case, flush it with a large quantity of water and wipe the cam-
era lens clean with a soft and wet cloth.
■Differences between the screen and the actual road
The distance guide lines and the vehicle width guide lines may not
actually be parallel with the dividing lines of the parking space, even
when they appear to be so. Be sure to check visually.
The distances between the vehicle width guide lines and the left
and right dividing lines of the pa rking space may not be equal, even
when they appear to be so. Be sure to check visually.
The distance guide lines give a distance guide for flat road sur-
faces. In any of the following situations, there is a margin of error
between the fixed guide lines on the screen and the actual dis-
tance/course on the road.

●When the ground behind the vehicle slopes up sharply
The distance guide lines will
appear to be closer to the
vehicle than the actual dis-
tance. Because of this,
objects will appear to be far-
ther away than they actually
are. In the same way, there
will be a margin of error
between the guide lines and
the actual dist ance/course on
the road.
● When the ground behind the vehi cle slopes down sharply
The distance guide lines will
appear to be farther from the
vehicle than the actual dis-
tance. Because of this,
objects will appear to be
closer than they actually are.
In the same way, there will be
a margin of error between
the guide lines and the actual
distance/course on the road.

●When any part of the vehicle sags
When any part of the vehicle
sags due to the number of
passengers or the distribu-
tion of the load, there is a
margin of error between the
fixed guide lines on the
screen and the actual dis-
tance/course on the road.
■When approaching thre e-dimensional objects
The distance guide lines are displa yed according to flat surfaced
objects (such as the road). It is not possible to determine the posi-
tion of three-dimensional objects (such as vehicles) using the vehi-
cle width guide lines and distanc e guide lines. When approaching a
three-dimensional object that extends outward (such as the flatbed
of a truck), be careful of the following.
● Vehicle width guide lines
Visually check the surround-
ings and the area behind the
vehicle. In the case shown
below, the truck appears to
be outside of the vehicle
width guide lines and the
vehicle does not look as if it
hits the truck. However, the
rear body of the truck may
actually cross over the vehi-
cle width guide lines. In real-
ity if you back up as guided
by the vehicle width guide
lines, the vehicle may hit the
truck.

●Distance guide lines
Visually check the surround-
ings and the area behind the
vehicle. On the screen, it
appears that a truck is park-
ing at point . However, in
reality if you back up to point
