Driving WARNING■
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 seco nds. 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 may
prevent the pre-collision braking func-
tion 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.
■
Active steering assist●
The steering wheel may turn automati-
cally when active steering assist is
operating.
●
As active steering assist operation will
be canceled when the system deter-
mines that a collision has been
avoided, operate the steering wheel as
necessary. ●
In the following situations, the system
may determine that th e driver is taking
evasive action. In this case, the active
steering assist may not operate or may
be canceled.
• If the accelerator pedal is being
depressed strongly or the steering
wheel is being operat ed. In this case
the system may determine that the
driver is taking evasive action and the
pre-collision braking may not operate.
• In some situations, while the active
steering assist 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.
• When the active steering assist is
operating, if the stee ring wheel is held
firmly or is operated in the opposite
direction to that which the system is
generating torque, the function may be
canceled.
• If the brake pedal is depressed, the sys-
tem may determine that the driver is
taking evasive action and the active
steering assist operation may be
delayed.
■
Pre-collision seat belts with comfort
function
If the pre-collision se at belts have oper-
ated and the seat belts are locked in a
retracted position, immediately stop the
vehicle in a safe place, release and
retract the seat belts to unlock them and
then fasten them again.
Also, if a seat belt ca n be loosened, it can
be unlocked by slightly retracting it with-
out releasing it.
■
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

Enabling/disabling the pre-colli-
sion system

enabled/disabled on ( → P.86) of
the multi-information display. The system is automa tically enabled each
time the power switch is turned to ON
mode
If the system is disabled, the PCS warn-
ing light will turn on and a message will
be displayed on the multi-information
display.
If the pre-collision sy stem is disabled,
the pedestrian alert system will also be
disabled. At this time, the FCTA (Front
Cross Traffic Alert) ( → P.227) system
will also be disabled.

In some situations, such as the following,
the sensors may not detect the lane lines
or a safe space the vehicle can be steered

218 4-5. Using the driving support systems
LS500h_OM_OM50F42U_(U) into, preventing the ac tive steering assist

repairs
• If the system determines that a collision
