while adjusting your speed by
depressing the brake pedal, to
reach the desired parking spot.
 Be sure to back up while check-
ing the area to the front and rear
of the vehicle directly and by
using the mirrors.
■Back-in parking assist mode oper-
ating conditions
●In order to operate the function cor-
rectly, 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-IPA switch.
●The function cannot be used when the
vehicle speed is approximately 30
km/h (19 mph) 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.311), 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.
●Depending on the condition of the parking 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 reach-
able.

■Tips for using the back-in parking assist mode
1 Leave a gap of approximately 1 m
(3.3 ft.) 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.
1 m (3.3 ft.)
2 Stop so that the center of the target parking spot is perpendicular to the
vehicle. Furthermore, only push the
S-IPA switch when the vehicle is at a complete stop.

●The sensor detection range when
using parallel parking assist mode
Intended parking spot
●When there is a parked vehicle behind
the target parking spot, it may not be
detected due to the distance. Also, depending on the shape of the vehicle
and other conditions, the detectable
range may shorten or detection may not be possible.
●Objects other than parked vehicles, such as poles and walls, may not be
detected. Also, even if these objects
can be detected, the target parking spot may deviate.
Poles
Wall
●Also, the target parking spot may devi- ate when a pedestrian, etc. is
detected.
Pedestrian
●The Simple Intelligent Parking Assist
System may not operate if grating, diamond plates or similar materials
are detected on the surface of the
parking space.
WA R N I N G
■When using the Simple Intelli- gent Parking Assist System
●Do not rely solely upon the Simple
Intelligent Parking Assist 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 sur-
rounding 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.

●Make sure to observe the following
precautions regarding the exit par-
allel parking assist mode. Exit parallel parking assist mode is
a function used when departing
from a parallel parking spot. How- ever, this function may not be usa-
ble if obstacles 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 oper-
ates, either turn the system off using the S-IPA switch or operate
the steering wheel to stop the con-
trol.
●If exit parallel parking assist mode
is mistakenly used in the following situations, 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 (situa- tions such as when the vehicle is
directly beside a pole).
●Observe the following precautions,
as the sensors may stop function-
ing 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 prop- erly if subjected to an impact from
strong water pressure. If the vehicle
bumper strikes something, equip- ment may not operate properly due
to a sensor malfunction. Have the
vehicle inspected at any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer.
●In the following situations, the sen- sors 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.265)
• Even after the scan of the side
areas is completed, obstacles such as other vehicles, people or ani-
mals 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 some- one’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 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 any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer.
• Do not install any accessories
within the sensor detection range.

3164-5. Using the driving support systems
■ABS (Anti-lock Brake System)
Helps to prevent wheel lock when
the brakes are applied suddenly, or
if the brakes are applied while driv-
ing on a slippery road surface
■Brake assist
Generates an increased level of
braking force after the brake pedal
is depressed when the system
detects a panic stop situation
■VSC (Vehicle St ability Control)
Helps the driver to control skidding
when swerving suddenly or turning
on slippery road surfaces.
■VSC+ (Vehicle Stability Con-
trol+)
Provides cooperative control of the
ABS, TRC, VSC and EPS.
Helps to maintain directional stabil-
ity when swerving on slippery road
surfaces by controlling steering per-
formance.
■TRC (Traction Control)
Helps to maintain drive power and
prevent the drive wheels from spin-
ning when starting the vehicle or
accelerating on slippery roads
■Active Cornering Assist (ACA)
Helps to prevent the vehicle from
drifting to the outer side by perform-
ing inner wheel brake control when
attempting to acce lerate while turn-
ing
■Hill-start assist control
Helps to reduce the backward
movement of the vehicle when
starting on an uphill
■EPS (Electric Po wer Steering)
Employs an electric motor to
reduce the amount of effort needed
to turn the steering wheel.
■Emergency brake signal
When the brakes are applied sud-
denly, the emergency flashers auto-
matically flash to alert the vehicle
behind.
■Secondary Collision Brake (if
equipped)
When the SRS airbag sensor
detects a collisi on and the system
operates, the brakes and brake
lights are automatically controlled
to reduce the vehicle speed and
help reduce the poss ibility of further
damage due to a secondary colli-
sion.
Driving assist systems
To keep driving safety and per-
formance, the following sys-
tems operate au tomatically in
response to various driving sit-
uations. Be aware, however,
that these systems are supple-
mentary and should not be
relied upon too heavily when
operating the vehicle.
