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
●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. 339)
• 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 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 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 in 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. 430)
• 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.

●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 displayed according to flat surfaced
objects (such as the road). It is not possible to determine the posi-
tion of three-dimensional objects (s uch as vehicles) using the vehi-
cle width guide lines and distance 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.

WARNING
■When using the rear view monitor system
The rear view monitor system is a supplemental device intended to assist
the driver when backing up. When backing up, be sure to visually check all
around the vehicle both directly and using the mirrors before proceeding.
Observe the following precautions to avoid an accident that could result in
death or serious injuries.
● Never depend on the rear view monitor system entirely when backing up.
The image and the position of the guide lines displayed on the screen may
differ from the actual state.
Use caution, just as you would when backing up any vehicle.
● Be sure to back up slowly, depressing the brake pedal to control vehicle
speed.
● The instructions given are only guide lines.
When and how much to turn the steering wheel will vary according to traf-
fic conditions, road surface conditions, vehicle condition, etc. when park-
ing. It is necessary to be fully aware of this before using the rear view
monitor system.
● When parking, be sure to check that the parking space will accommodate
your vehicle before maneuvering into it.
● Do not use the rear view monitor system in the following cases:
• On icy or slick road surfaces, or in snow
• When using tire chains or emergency tires
• When the back door is not closed completely
• On roads that are not flat or straight, such as curves or slopes
● In low temperatures, the screen may darken or the image may become
faint. The image could distort when the vehicle is moving, or you may
become unable to see the image on the screen. Be sure to visually check
all around the vehicle both directly and using the mirrors before proceed-
ing.
● If the tire sizes are changed, the position of the fixed guide lines displayed
on the screen may change.
● The camera uses a special lens. The distances between objects and
pedestrians that appear in the image displayed on the screen will differ
from the actual distances. ( →P. 395)
