4-5. Using the driving support systems

Driving

Pedestrian alert

When the system determines that 
there is a possibility of a frontal collision 
with a stationary or moving pedestrian 
in front of your vehicle, a message will 
be displayed on the head-up display to 
warn the driver.

Pre-collision warning

When the system determines that the 
possibility of a frontal collision is high, a 
buzzer will sound and a warning mes-
sage will be displayed on the 
multi-information display to urge the 
driver to take evasive action.

Pre-collision brake assist

When the system determines that the 
possibility of a frontal collision is high, 
the system applies greater braking 
force in relation to how strongly the 
brake pedal is depressed.

Pre-collision braking

If the system determines that the possi-
bility of a frontal collision is extremely 
high, the brakes are automatically 
applied to help avoid the collision or 
reduce the impact of the collision.

PCS (Pre-Collision System) 
(vehicles with Lexus Safety 
System + A)

The pre-collision system uses a 
front radar sensor and front camera 
to detect vehicles and pedestri-
ans/bicyclists in front of your vehi-
cle and front side radar sensors to 
detect vehicles approaching from 
the front left or right side. When the 
system determines that the possi-
bility of a frontal collision with a 
vehicle or pedestrian/bicyclist is 
high, a warning operates to urge 
the driver to take evasive action 
and the potential brake pressure is 
increased to help the driver avoid 
the collision. If the system deter-
mines that the possibility of a frontal 
collision with a vehicle or pedes-
trian/bicyclist is extremely high, the 
brakes are automatically applied to 
help avoid the collision or help 
reduce the impact of the collision.

The pre-collision system can be disa-
bled/enabled and the warning timing 
can be changed. (

P.217)

System functions

4-5. Using the driving support systems

Intersection right/left turn assis-
tance

If the system determines that there is a 
high possibility of a collision in the fol-
lowing situations, it will assist with 
Pre-collision warning and, if necessary 
Pre-collision braking. Depending on 
the configuration of the intersection, it 
may not be possible to support.

When you turn right/left at an inter-
section and cross the path of an 
oncoming vehicle

When you turn right/left, pedestrian 
is detected in the forward direction 
and estimated to enter your vehi-
cle’s path (bicyclists are not 
detected.)

Active steering assist

If the system determines that the possi-
bility of a collision with an object, such 

as a guardrail, or pedestrian is high, 
even though the brakes are applied, 
and that the collision may be avoidable 
through steering control, the system 
will steer the vehicle automatically to 
help avoid the collision or help reduce 
the impact of the collision.

Active Assist for seat belts (front 
seats only)

If the system determines that the possi-
bility of a frontal collision is high, the 
system will retract the seat belts. Addi-
tionally, the system may retract the seat 
belts if the brakes are applied suddenly 
or control of the vehicle is lost.

Pre-collision seatbacks (front pas-
senger’s seat / power rear seat [if 
equipped])

If the system determines that the possi-
bility of a frontal collision is high, it may 
move the seatbacks of the front pas-
senger’s seat and power rear seats to 
the upright position automatically, if 
reclined.

If a seat is being adjusted, it may not be 
moved by the pre-collision seat function.

Suspension control

When the system determines that the 
possibility of a frontal collision is high, 
the Adaptive Variable Suspension Sys-
tem (

P.322) will control the damp-

ing force of the shock absorbers to 
help maintain an appropriate vehicle 
posture.

Driving

WARNING

Limitations of the pre-collision system

The driver is solely responsible for safe 

driving. Always drive safely, taking 

care to observe your surroundings.

Do not use the pre-collision system 

instead of normal braking operations 

under any circumstances. This system 

will not prevent collisions or lessen col-

lision damage or injury in every situa-

tion. Do not overly rely on this system. 

Failure to do so may lead to an acci-

dent, resulting in death or serious 

injury.

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.220

• Conditions under which the system 

may not operate properly: 

P.223

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.

In some situations, while the pre-colli-

sion 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 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 the 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 operated. In this case 

the system may determine that the 

driver is taking evasive action and the 

pre-collision braking may not operate.

WARNING

• 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 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.

• 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.

Active Asssit for seat belts

If the Active Assist has operated and the 

seat belts are locked in a retracted posi-

tion, 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 can 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

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 engine running and the tires are 

allowed to rotate freely

When inspecting the vehicle using a 

drum tester such as a chassis 

dynamometer or speedometer tester, 

or when using an on vehicle wheel bal-

ancer

When a strong impact has been 

applied to the front bumper, rear 

bumper or front grille, due to an acci-

dent 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

When a compact spare tire or an 

emergency tire puncture repair kit is 

used

If equipment (snow plow, etc.) that may 

obstruct a radar sensor or the front 

camera is temporarily installed to the 

vehicle

Driving

The system is automatically enabled each 
time the engine switch is turned to IGNI-
TION 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 system is disabled, 
the pedestrian alert system will also be 
disabled.

multi-information display.

The warning timing setting is retained 
when the engine switch is turned off. How-
ever, if the pre-collision system is disabled 
and re-enabled, the operation timing will 
return to the default setting (middle).

If the pre-collision warning timing is 
changed, the pedestrian alert timing 
will also be changed accordingly.

Operational conditions

The pre-collision system is enabled and the system determines that the possibility of a frontal 

collision with a vehicle, pedestrian/bicyclist, guardrail, etc. or a front side collision with a 

vehicle is high.
The system may not operate in the following situations:

If a battery terminal has been disconnected and reconnected and then the vehicle has not 

been driven for a certain amount of time
