4-5. Using the driving support systems
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.207
• Conditions under which the system
may not operate properly: →P.208
●
Do not attempt to test the operation of
the pre-collision system yourself, as 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.
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 speedometer 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
When the tires are very worn
●
When tires of a size other than speci-
●
fied are installed
●
When tire chains are installed
