260 4-5. Using the driving support systems
LS500_OM_OM50F54U_(U) ●
A shift position other than P is selected.■
Setting the buzzer volume
The buzzer volume can be adjusted on the
multi-information display. ( → P.257)■
If “Parking Assist Unavailable Clean
Parking Assist Sensor” is displayed on
the multi-inform ation display
A sensor may be covered with ice, snow,
dirt, etc. Remove the ice, snow, dirt, etc.,
from the sensor to return the system to nor-
mal.
Also, due to ice forming on a sensor at low
temperatures, a warning message may be
displayed or the sensor may not be able to
detect an object. Once the ice melts, the
system will return to normal. ■
Sensor detectio n information●
The following situations may occur
during use.
• Depending on the shape of the object
and other factors, the detection distance
may shorten, or detection may be impos-
sible.
• There will be a short delay between
object detection and display. Even at low
speeds, there is a possibility that the
object will come within the sensor’s
detection areas before the display is
shown and the warning beep sounds.
• It might be difficult to hear the buzzer due
to the volume of the audio system or air
flow noise of the air conditioning system.■
Conditions under which the function
may not function correctly
Certain vehicle conditions and the sur-
rounding environment may affect the ability
of a sensor to correctly detect objects. Par-
ticular instances where this may occur are
listed below.
●
There is dirt, snow or ice on a sensor.
(Cleaning the sensors will resolve this
problem.)
●
A sensor is frozen. (Thawing the area will
resolve this problem.)
In especially cold weather, if a sensor is
frozen the sensor display may be dis-
played abnormally, or objects, such as a
wall, may not be detected.
●
A sensor is covered in any way. ●
When a sensor or the area around a sen-
sor is extremely hot or cold. ●
On an extremely bumpy road, on an
incline, on gravel, or on grass. ●
The vicinity of the vehicle is noisy due to
vehicle horns, motorcycle engines, air
brakes of large vehicles, or other loud
noises producing ultrasonic waves. ●
There is another vehicle equipped with
parking assist sensors in the vicinity. ●
A sensor is coated with a sheet of spray
or heavy rain. ●
If a sensor is hit by a large amount of
water, such as when driving on a flooded
road. ●
If the vehicle is significantly tilted. ●
The vehicle is approaching a tall or
curved curb. ●
If objects draw too close to the sensor. ■
Objects which may not be properly
detected
The shape of the object may prevent the
sensor from detectin g it. Pay particular
attention to the following objects: ●
Wires, fences, ropes, etc. ●
Cotton, snow and other materials that
absorb sound waves ●
Sharply-angled objects ●
Low objects ●
Tall objects with upper sections project-
ing outwards in the direction of your vehi-
cle
People may not be de tected if they are
wearing certain types of clothing.

270 4-5. Using the driving support systems
LS500_OM_OM50F54U_(U) • Pedestrians who are bending forward or
squatting
• Pedestrians who are lying down
• Pedestrians who are running
• Pedestrians who suddenly enter the
detection area
• Pedestrians riding a bicycle, skateboard,
or other light vehicle
• Pedestrians wearing oversized clothing
such as a rain coat, long skirt, etc., making
their silhouette obscure
• Pedestrians whose body is partially hid-
den by an object, such as a cart or
umbrella
• Pedestrians which are obscured by dark-
ness, such as at night●
In some situations, such as the following,
pedestrians may not be detected by the
rear camera detection function, prevent-
ing the function from operating properly:
• When backing up in inclement weather
(rain, snow, fog, etc.)
• When the rear camera is obscured (dirt,
snow, ice, etc. are attached) or scratched
• When a very bright light, such as the sun,
or the headlights of another vehicle,
shines directly into the rear camera
• When backing up in a place where the
surrounding brightness changes sud-
denly, such as at the entrance or exit of a
garage or underground parking lot
• When backing up in a dim environment
such as during dusk or in an underground
parking lot●
Even though there are no pedestrians in
the detection area, some objects, such as
the following, may be detected, possibly
causing the rear camera detection func-
tion to operate.
• Three dimensional objects, such as a
pole, traffic cone, fence, or parked vehi-
cle
• Moving objects, such as a car or motor-
cycle
• Objects moving toward your vehicle
when backing up, such as flags or pud-
dles (or airborne matter, such as smoke,
steam, rain, or snow)
• Cobblestone or gravel roads, tram rails,
road repairs, white lines, pedestrian
crossings or fallen leaves on the road
• Metal covers (gratings), such as those
used for drainage ditches • Objects reflected in a puddle or on a wet
road surface
• The roadside or bumps on the road
•Shadows on the road ●
In some situations, such as the following,
the rear camera detection function may
operate even though there are no pedes-
trians in the detection area.
• When backing up toward the roadside or
a bump on the road
• If the vehicle is signif icantly tilted, such as
when carrying a heavy load
• When backing up toward an
incline/decline
• If the suspension has been modified or
tires of a size othe r than specified are
installed
• If the rear of the vehicle is raised or low-
ered due to the carried load
• If an electronic component, such as a
backlit license plate or rear fog light, is
installed near the rear camera
• If a bumper protector, such as an addi-
tional trim strip, is installed to the rear
bumper
• If the orientation of the rear camera has
been changed due to a collision or other
impact, or removal and installation
• If a towing eyelet is in stalled to the rear of
the vehicle
• When water is flowing over the rear cam-
era lens
• When the rear camera is obscured (dirt,
snow, ice, etc. are at tached) or scratched
• If there is a flashing light in the detection
area, such as the emergency flashers of
another vehicle ●
Situations in which the rear camera
detection function may be difficult to
notice
• If buzzer may be difficult to hear if the
surrounding area is noisy, the volume of
the audio system volume is high, the air
conditioning system is being used, etc.
• If the temperature in the cabin is
extremely high or low, the audio system
screen may not operate correctly.
