■Objects which the system may
not be properly detected
The shape of the object may pre-
vent the sensor from detecting it.
Pay particular attention to the follow-
ing 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 abnormally,
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 ot her 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.
●Strong wind is 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 that may
obstruct a sensor is installed, such
as a towing eyelet, bumper pro-
tector (an additional trim strip,
etc.), bicycle car rier, or snow plow
●If the front of the v ehicle 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 a tire chains, compact
spare tire or an emergency tire
puncture repair kit is used

PKSB (Parking Sup-
port Brake)*
The Parking Support Brake
system consists of the fol-
lowing functions that oper-
ate when driving at a low
speed or backing up, such
as when parking. When the
system determines that the
probability of a collision
with a detected object or
pedestrian is high, a warn-
ing operates to urge the
driver to take evasive
action. If the system deter-
mines that the possibility of
a collision with a detected
object or pedestrian is
extremely high, the brakes
are automatically applied to
help avoid the collision or
help reduce the impact of
the collision.
PKSB (Parking Support
Brake) system

3905-4. Using the driving support systems
Owners Manual_USA_M42C01_entem is reduced to prevent the sys-
tem from overheating when there is
frequent steering input over an
extended period of time. The steer-
ing wheel may feel heavy as a
result. Should this occur, refrain
from excessive steering input or
stop the vehicle and turn the EV
system off. The E
PS system should
return to normal wit hin 10 minutes.
■Secondary Collision Brake
operating conditions
The system operates when the SRS
airbag sensor detects a collision
while the vehicle is in motion. How-
ever, the system does not operate
when the components are dam-
aged.
■Secondary Collision Brake
automatic cancellation
The system is automatically can-
celed in any of th e following situa-
tions.
●The vehicle speed drops to
approximately 0 mph (0 km/h)
●A certain amount o f time elapses
during operation
●The accelerator pedal is
depressed a large amount
