4-5. Using the driving support systems
WARNING
• Conditions under which the system
may not operate properly:
●
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, possibly leading to an
accident.
■
Pre-collision braking
●
When the pre-collision braking
function is operating, a large
amount of braking force will be
applied.
●
If the vehicle is stopped by the
operation of the pre-collision brak-
ing function, the pre-collision brak-
ing function operation will be
canceled after approximately 2 sec-
onds. Depress the brake pedal as
necessary.
●
The pre-collision braking function
may not operate if certain opera-
tions are performed by the driver. If
the accelerator pedal is being
depressed strongly or the steering
wheel is being turned, the system
may determine that the driver is tak-
ing evasive action and possibly pre-
vent the pre-collision braking
function from operating.
●
In some situations, while the
pre-collision braking function is
operating, operation of the function
may be canceled if the accelerator
pedal is depressed strongly or the
steering wheel is turned and the
system determines that the driver is
taking evasive action.
●
If the brake pedal is being
depressed, the system may deter-
mine that the driver is taking eva-
P.192
sive action and possibly delay the
operation timing of the pre-collision
braking function.
■
Emergency steering assist
●
As emergency steering assist oper-
ation will be canceled when the sys-
tem determines that lane departure
prevention function has been com-
pleted.
●
Emergency steering assist may not
operate or may be cancel in the fol-
lowing cases as the system may
determine the driver is taking
actions.
• If the accelerator pedal is being
depressed strongly, the steering
wheel is being operated sharply,
the brake pedal is being depressed
or the turn signal lever is being
operated. In this case, the system
may determine that the driver is tak-
ing evasive action and the emer-
gency steering assist may not
operate.
• In some situations, while the emer-
gency steering assist is operating,
operation of the function may be
canceled if the accelerator pedal is
depressed strongly, the steering
wheel is operated sharply or the
brake pedal is being depressed and
the system determines that the
driver is taking evasive action.
• When the emergency steering
assist is operating, if the steering
wheel is held firmly or is operated in
the opposite direction to that which
the system is generating torque, the
function may be canceled.
