4-5. Using the driving support systems
WARNING
Cautions regarding the use of the sys-
tem
Do not overly rely on the system, as
doing so may lead to an accident. Always
drive while checking the safety of the sur-
roundings of the vehicle.
Depending on the vehicle and road con-
ditions, weather, etc., the system may not
operate.
The detection capabilities of sensors,
radars and camera are limited. Always
drive while checking the safety of the sur-
roundings of the vehicle.
The driver is solely responsible for safe
driving. Always drive carefully, taking
care to observe your surroundings.
The PKSB (Parking Support Brake)
system is designed to provide support
to lessen the severity of collisions.
However, it may not operate in some
situations.
The PKSB (Parking Support Brake)
system is not designed to stop the
vehicle completely. Additionally, even
if the system has stopped the vehicle, it
is necessary to depress the brake
pedal immediately as brake control will
be canceled after approximately 2
seconds.
It is extremely dangerous to check the
system operations by intentionally
driving the vehicle into the direction of
a wall, etc. Never attempt such actions.
When to disable the PKSB (Parking
Support Brake) system
In the following situations, disable the
PKSB (Parking Support Brake) as the
system may operate even though there is
no possibility of a collision.
When inspecting the vehicle using a
chassis roller, chassis dynamo or free
roller
When loading the vehicle onto a boat,
truck or other transport vessel
If the suspension has been modified or
tires of a size other than specified are
installed
If the front of the vehicle is raised or
lowered due to the carried load
When equipment that may obstruct a
sensor is installed, such as a towing
eyelet, bumper protector (an addi-
tional trim strip, etc.), bicycle carrier, or
snow plow
When using automatic car washing
devices
If the vehicle cannot be driven in a sta-
ble manner, such as when the vehicle
has been in an accident or is malfunc-
tioning
When the vehicle is driven in a sporty
manner or off-road
When the tires are not properly
inflated
When the tires are very worn
When a tire chains or compact spare
tire is used
When your vehicle is towing a trailer
or during emergency towing
Precautions for the suspension
Do not modify the suspension of the
vehicle. If the height or tilt of the vehicle is
changed, the sensors may not be able to
detect detectable objects and the system
may not operate correctly, possibly lead-
ing to an accident.
