5-5. Using the driving support systems
Assume an ordinary driving postu re, rest your hands lightly on
the steering wheel without applying any force, directly confirm
the safety of the area to the front and around the vehicle and
slowly proceed forward while adjusting your speed by depressing
the brake pedal.
When the vehicle has nearly
reached the take-off point, a
high-pitched beep is emitted
and assist control finishes.
From there, grasp the steer-
ing wheel and proceed for-
ward.
■ Exit parallel parking assist mode
●During assist control, if the driver determines that they are a t a position
where take-off is possible and operates the steering wheel, ass ist control is
stopped at that position.
● Assist control cannot be used if there are no parked vehicles a head, or if the
gap between the front of your vehicle and the vehicle parked ahead is too
large.
● When using the exit parallel parking assist mode, the assist mode may not
be able to operate depending on the surrounding environment.

the safety of your surroundings, and if there is a possibility of a contact
accident, stop the vehicle by depressing the brake pedal.
● It may not be possible to detect objects that are low to the gr ound. Directly
confirm the safety of your surroundings and, if it seems the vehicle may
make contact with an obstacle, stop the vehicle by depressing the brake
pedal.

Driving
Assume an ordinary posture for backing up, rest your hands
lightly on the steering wheel without applying any force, direc tly
confirm the safety of the area to the rear and around the vehic le
slowly back up while adjusting your speed by depressing the
brake pedal.
Depending on the condition of the parking space, steps to may
need to be repeated.
When the vehicle is almost entire ly within the target parking spot,
a high-pitched beep is emitted and the stop display is shown on
the display ( P. 455), stop the vehicle.
This completes the back-in parking assist mode.
● For safety, the buzzer sounds slightly before the vehicle is
completely entered within the target parking spot. Further-
more, at that point, system operation will also finish. Firmly
hold the steering wheel and slowly back up while adjusting
your speed by depressing the brake pedal to reach the desired
parking spot.
● Be sure to back up while checking the area to the front and
rear of the vehicle direct ly and by using the mirrors.
■Back-in parking assist m ode operating conditions
● In order to operate the function correctly, drive slowly (at a speed at which
the vehicle can be quickly stopped).
● In order to operate the function correctly, drive slowly (at a speed at which
the vehicle can be quickly stopped). Come to a full stop so tha t the center of
the parking space is nearly perpendicular to the vehicle, and t hen operate
the S-APGS switch.
● The function cannot be used when the vehicle speed is approxima tely
19 mph (30 km/h) or higher.
● The front side sensors and rear side sensors are used to detect parked
vehicles and determine the parking spot. Therefore, when detection is not
possible ( P. 484), guidance is not issued.
● If there are no parked vehicles, the parking spot cannot be det ermined.
Therefore, the back-in parking assist mode cannot be operated.
● If unable to detect the environment surrounding the parking space, the
back-in parking assist mode may not be able to operate.

■Tips for using the back-in parking assist mode ●Depending on the condition of the park-
ing space, if there is not enough space
in front of the vehicle required to perform
the parking operation, the target parking
spot may not be reachable.
Intended parking spot
Wall
● Leave a gap of approximately 3.3 ft. (1
m) from any parked vehicles and
approach the target parking spot. If the
gap between your vehicle and any
parked vehicles is too large, the front
side sensors and rear side sensors may
not be able to detect the parked vehi-
cles.
● Stop so that the center of the target
parking spot is perpendicular to the vehi-
cle. Furthermore, only push the S-APGS
switch when the vehicle is at a complete
stop.
NOTICE
●If the road surface has any dips or inclines, the target parking spot cannot
be correctly set. Therefore, the vehicle may be parked at an an gle or may
deviate from the parking spot. In these cases, do not use the back-in park-
ing assist mode.
● When parking in a narrow space, the vehicle will come close to adjacent
vehicles. If it seems the vehicle may make contact, stop the ve hicle by
depressing the brake pedal.
● It may not be possible to detect objects that are low to the gr ound. Directly
confirm the safety of your surroundings and, if it seems the vehicle may
make contact with an obstacle, stop the vehicle by depressing the brake
pedal.
● Depending on the surrounding environment, such as other parked vehi-
cles, the vehicle may be parked at an angle or may deviate from the park-
ing spot. Manually adjust vehicle alignment as necessary.

WARNING
●Observe the following precautions, as the sensors may stop func tioning
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, equipment may not operate properly du e 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. 434)
• 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. Have the
vehicle inspected at your Toyota dealer.
• Do not install any accessories within the sensor detection ran ge.
