■Exposure to radio fre-
quency signals
The Safety Connect system 
installed in your vehicle is a low-
power radio transmitter and 
receiver. It receives and also 
sends out radio frequency (RF) 
signals.
In August 1996, the Federal 
Communications Commission 
(FCC) adopted RF exposure 
guidelines with safety levels for  mobile wireless phones. Those 
guidelines are consistent with 
the safety standards previously 
set by the following U.S. and 
international standards bodies.
ANSI (American National 
Standards Institute) C95.1 
[1992]
 NCRP (National Council on 
Radiation Protection and 
Measurement) Report 86 
[1986]
 ICNIRP (International Com-
mission on Non-Ionizing Radi-
ation Protection) [1996]
Those standards were based on 
comprehensive and periodic 
evaluations of the relevant sci-
entific literature. Over 120 scien-
tists, engineers, and physicians 
from universities, and govern-
ment health agencies and 
industries reviewed the avail-
able body of research to 
develop the ANSI Standard 
(C95.1).
The design of Safety Connect 
complies with the FCC guide-
lines in addition to those stan-
dards.

vehicle
• When turning left/right and the  direction of the vehicle differs 
greatly from the direction traffic 
flows in the oncoming lane
• When turning left/right, a pedes- trian or bicycle behind the vehicle 
comes in front of it as if it over-
takes the vehicle
• When at an intersection, the  approaching crossing vehicle is 
long in overall le ngth, such as a 
large truck, towing trailer, etc. 
●In addition to the preceding, in 
certain situations, such as the fol-
lowing, the emergency steering 
assist may not operate properly:
• When a detectable object is too 
close to the vehicle
• When there is insufficient space to  perform evasive steering maneu-
vers or an obstruction exists in the 
evasion direction
• When there is an oncoming vehi-
cle
●In addition to the preceding, in 
certain situations, such as the fol-
lowing, walls may not be detected 
as a target object and the Acceler-
ation Suppression at Low Speed 
function may not operate properly:
• When scenery behind the wall is  visible, such as a glass door, grid 
fence, etc.  • When the wall is slanted or low
• When the wall is narrow, such as 
a pole, etc. 
• When the wall is made of plants,  such as a hedge, etc. 
• When the road, etc. is reflected on 
the wall
• When the vehicle is approaching  the wall at an angle
 The pre-collision system can 
be enabled/disabled through 
a customize setting. 
( P.626)
The system is enabled each time 
the power switch is turned to ON.
When the system is disabled, 
the PCS warning light will illu-
minate and a message will be 
displayed on the multi-infor-
mation display.
 The pre-collision setting can 
be changed on the customize 
settings. ( P.626)
 Vehicles without active steer-
ing function: When the pre-
collision warning timing is 
changed, the emergency 
steering assist timing will also 
be changed.
When later is selected, the 
emergency steering assist will 
not operate in most cases.
 Vehicles with active steering 
function: When the pre-colli-
sion warning timing is 
changed, the emergency

■Objects which the system may 
not properly detect
The shape of the object may pre-
vent the sensor from detecting it. 
Pay particular attention to the fol-
lowing objects:
●Wires, fences, ropes, etc.
●Cotton, snow and other materials 
that absorb sound waves
●Sharply-angled objects
●Low objects
●Tall objects with upper sections 
projecting outwards in the direc-
tion of your vehicle
People may not be detected if they 
are wearing certain types of cloth-
ing.
■Situations in which the system 
may not operate properly
Certain vehicle conditions and the 
surrounding environment may affect 
the ability of a sensor to correctly 
detect objects. Particular instances 
where this may occur are listed 
below.
●There is dirt, snow, water drops 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 dis-
play may be displayed abnor-
mally, or objects,  such as a wall, 
may not be detected.
●When a sensor or the area around 
a sensor is extremely hot or cold.
●On an extremely bumpy road, on 
an incline, on gravel, or on grass.
●When vehicle horns, vehicle 
detectors, motorcycle engines, air 
brakes of large vehicles, the clear-
ance sonar of other vehicles or 
other devices which produce ultra-
sonic waves are near the vehicle.
●A sensor is coated with a sheet of 
spray or heavy rain.
●If objects draw too close to the 
sensor.
●When a pedestrian is wearing 
clothing that does not reflect ultra-
sonic waves (ex. skirts with gath-
ers or frills).
●When objects that are not perpen-
dicular to the ground, not perpen-
dicular to the vehicle traveling 
direction, uneven, or waving are in 
the detection range.
●When strong winds are blowing.
●When driving in inclement weather 
such as fog, snow or a sandstorm.
●When an object that cannot be 
detected is between the vehicle 
and a detected object.
●If an object such as a vehicle, 
motorcycle, bicycle or pedestrian 
cuts in front of the vehicle or runs 
out from the side of the vehicle.
●If the orientation of a sensor has 
been changed due to a collision or 
other impact.
●When equipment such as a towing 
eyelet, transport hook, bumper 
protector, bumper trim, bicycle 
carrier or snow-removal device 
(snow plow) is installed near the 
sensor.
●If the front of the vehicle is raised 
or lowered due to the carried load.
●If the vehicle cannot be driven in a 
stable manner, such as when the 
vehicle has been in an accident or 
is malfunctioning.
●When tire chains, a compact 
spare tire or an emergency tire 
puncture repair kit are used.

●In some situations, such as the 
following, pedestrians may not be 
detected by the rear camera 
detection function, preventing 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 suddenly, such as at the 
entrance or exit of a garage or 
underground parking lot
• When backing up in a dim envi-
ronment such as during dusk or in 
an underground parking lot
• When the camera position and 
direction are deviated
• When a towing hook is attached
• When towing with the vehicle
• When water droplets are flowing  on the camera lens
• When the vehicle height is  extremely changed (nose up, 
nose down, etc.)
• When tire chains or an emergency  tire puncture repair kit are used

ent size than the genuine tires are  installed
• When an aftermarket electronic  part (backlit license plate, fog 
light, etc.) is insta lled near the rear 
camera
• If a bumper protector, such as an 
additional trim strip, is installed to 
the rear bumper
■Situations in which the system 
may operate unexpectedly
●Even though there are no pedes-
trians in the detection area, some 
objects, such as the following, 
may be detected, possibly caus-
ing the rear camera detection 
function to operate.
• Three dimensional objects, such  as a pole, traffic cone, fence, or 
parked vehicle
• Moving objects, such as a car or  motorcycle
• Objects moving toward your vehi- cle when backing up, such as 
flags or puddles (or airborne mat-
ter, such as smoke, steam, rain, or 
snow)
• Cobblestone or gravel roads, tram 
rails, road repair s, 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
• Shadows on the road
●In some situations, such as the 
following, the rear camera detec-
tion function may operate even 
though there are no pedestrians in 
the detection area.
• When backing up toward the road-
side or a bump on the road
• When backing up toward an  incline/decline
• When the vehicle height is  extremely changed (nose up, 
nose down, etc.)
• If a bumper protector, such as an 
additional trim strip, is installed to 
the rear bumper
• When an aftermarket electronic 
part (backlit license plate, fog 
light, etc.) is insta lled near the rear

PKSB (Parking Sup-
port Brake)*
The PKSB (Parking Support 
Brake) is a system that 
issues warnings and auto-
matically performs braking 
to help reduce collision 
damage with operation tar-
gets that were detected 
when traveling at a low 
speed such as when park-
ing.
This system consists of the 
following functions: a Park-
ing Support Brake function 
(static objects to the front 
and rear) that detects static 
objects such as walls, a 
Parking Support Brake 
function (rear-crossing 
vehicles)
* that detects vehi-
cles approaching from the 
rear while backing up, a 
Parking Support Brake 
function (rear pedestrians)
* 
that detects pedestrians 
behind the vehicle, and a 
Parking Support Brake 
function (static objects 
around the vehicle) (vehi-
cles with Advanced Park) 
that detects static objects 
around the vehicle.
