Driving
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 adjus ting 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 at a position
where take-off is possible and operates the steering wheel, assist control is
stopped at that position.
● Assist control cannot be used if there are no parked vehicles ahead, 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 be
not be able to operate depending on the surrounding environment.

NOTICE
●The detection range of the sensors ( →P. 424) is limited. Directly confirm
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 ground. 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.
● When departing for a position from which you can take off, directly confirm
the safety of your surroundings.

5-5. Using the driving support systems
Assume an ordinary posture for backing up, rest your hands
lightly on the steering wheel wi thout applying any force, directly
confirm the safety of the area to the rear and around the vehicle
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 entirely within the target parking spot,
a high-pitched beep is emitted and the stop display is shown on
the display ( →P. 446), 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 o peration 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 directly and by using the mirrors.
■Back-in parking assist mode 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 that the center of
the parking space is nearly perpendicular to the vehicle, and then operate
the S-APGS switch.
● The function cannot be used when the vehicle speed is approximately
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. 475), guidance is not issued.
● If there are no parked vehicles, the parking spot cannot be determined.
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
vehicles.
Stop so that the center of the target
parking spot is perpendicular to the
vehicle. 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 angle 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 vehicle by
depressing the brake pedal.
● It may not be possible to detect objects that are low to the ground. 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 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. 425)
• 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.

ily unavailable, possibly due to either of the following:
• An area around the radar sensor or camera sensor being dirty or covered with condensation, ice, stickers,
etc.
→ Clear the dirt, condensation, ice, stickers, etc.
(→P. 364)
• Radar sensor or camera sensor operational conditions (such as temperature etc.) being not met
→ Driving is possible in th is case. The PCS (Pre-Colli-
sion System) will be enabled if the operational condi-
tions (such as temperature etc.) are met again.
