WARNING
Although this system is designed to
●
help avoid a collision or help reduce
the impact of the collision, its effective-
ness may change according to various
conditions, therefore the system may
not always be able to achieve the same
level of performance.
Read the following conditions care-
fully. Do not overly rely on this system
and always drive carefully.
• Conditions under which the system
may operate even if there is no possi-
bility of a collision: P.214
• Conditions under which the system
may not operate properly: P.215
● Do not attempt to test the operation of
the pre-collision system yourself.
Depending on the objects used for
testing (dummies, cardboard objects
imitating detectable objects, etc.), the
system may not operate properly, pos-
sibly leading to an accident.
Pre-collision braking
■
● When the pre-collision braking func-
tion is operating, a large amount of
braking force will be applied.
If the vehicle is stopped by the opera-
●
tion of the pre-collision braking func-
tion, the pre-collision braking function
operation will be canceled after
approximately 2 seconds. Depress the
brake pedal as necessary.
The pre-collision braking function may
●
not operate if certain operations are
performed by the driver. If the acceler-
ator pedal is being depressed strongly
or the steering wheel is being turned,
the system may determine that the
driver is taking evasive action and pos-
sibly prevent the pre-collision braking
function from operating.
4-5. Using the driving support systems
In some situations, while the pre-colli-
●
sion braking function is operating,
operation of the function may be can-
celed if the accelerator pedal is
depressed strongly or the steering
wheel is turned and the system deter-
mines that the driver is taking evasive
action.
If the brake pedal is being depressed,
●
the system may determine that the
driver is taking evasive action and pos-
sibly delay the operation timing of the
pre-collision braking function.
When to disable the pre-collision sys-
■
tem
In the following situations, disable the
system, as it may not operate properly,
possibly leading to an accident resulting
in death or serious injury:
● When the vehicle is being towed
● When your vehicle is towing another
vehicle
When transporting the vehicle via
●
truck, boat, train or similar means of
transportation
When the vehicle is raised on a lift with
●
the hybrid system on and the tires are
allowed to rotate freely
When inspecting the vehicle using a
●
drum tester such as a chassis dyna-
mometer or speedmeter tester, or
when using an on vehicle wheel bal-
ancer
When a strong impact is applied to the
●
front bumper or front grille, due to an
accident or other reasons
● 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
