WARNING

■

When refueling the vehicle

Observe the following precautions while

refueling the vehicle. Failure to do so may

result in death or serious injury.

●

After exiting the vehicle and before

opening the fuel door, touch an

unpainted metal surface to discharge

any static electricity. It is important to

discharge static electricity before refu-

eling because sparks resulting from

static electricity can cause fuel vapors

to ignite while refueling.

●

Always hold the grips on the fuel tank

cap and turn it slowly to remove it.

A whooshing sound may be heard

when the fuel tank cap is loosened.

Wait until the sound cannot be heard

before fully removing the cap. In hot

weather, pressurized fuel may spray

out the filler neck and cause injury.

●

Do not allow anyone that has not dis-

charged static electricity from their

body to come close to an open fuel

tank.

●

Do not inhale vaporized fuel.

Fuel contains substances that are

harmful if inhaled.

●

Do not smoke while refueling the vehi-

cle.

Doing so may cause the fuel to ignite

and cause a fire.

●

Do not return to the vehicle or touch

any person or object that is statically

charged.

This may cause static electricity to

build up, resulting in a possible ignition

hazard.

■

When refueling

Observe the following precautions to

prevent fuel overflowing from the fuel

tank:

●

Securely insert the fuel nozzle into the

fuel filler neck.

●

Stop filling the tank after the fuel noz-

zle automatically clicks off.

●

Do not top off the fuel tank.

■

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 dis-
abled/enabled and the warning tim-
ing can be changed. (

■

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.305) will control the damp-

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

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.214

• Conditions under which the system

may not operate properly:



P.216

●

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 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.

210

4-5. Using the driving support systems

WARNING

●

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.

• 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.

■
