■

If a warning message is displayed on the multi-information display

A system may be temporarily unavailable or there may be a malfunction in the system.

●

In the following situations, perform the actions specified in the table. When the normal

operating conditions are detected, the message will disappear and the system will

become operational.

If the message does not disappear, contact your Lexus dealer.

Situation

Actions

When the area around a camera is covered
with dirt, moisture (fogged up, covered with
condensation, ice, etc.), or other foreign
matter

Using the wiper and A/C function, remove
the dirt and other attached matter.
(

P.286)

When the temperature around the front
camera is outside of the operational range,
such as when the vehicle is in the sun or in an
extremely cold environment

If the front camera is hot, such as after the
vehicle had been parked in the sun, use the
air conditioning system to decrease the tem-
perature around the front camera.
If a sunshade was used when the vehicle
was parked, depending on its type, the sun-
light reflected from the surface of the sun-
shade may cause the temperature of the
front camera to become excessively high.

If the front camera is cold, such after the
vehicle is parked in an extremely cold envi-
ronment, use the air conditioning system to
increase the temperature around the front
camera.

Driving

●

In the following situations, if the situation has changed (or the vehicle has been driven for

some time) and the normal operating conditions are detected, the message will disappear

and the system will become operational.

If the message does not disappear, contact your Lexus dealer.

• When the temperature around the radar sensor is outside of the operational range, such

as when the vehicle is in the sun or in an extremely cold environment

• When the front camera cannot detect objects in front of the vehicle, such as when driving

in the dark, snow, or fog, or when bright lights are shining into the front camera

• Depending on the conditions in the vicinity of the vehicle, the radar may judge the sur-

rounding environment cannot be properly recognized. In that case, “Pre-Collision System

Unavailable” is displayed.

The area in front of the front camera is
obstructed, such as when the hood is open
or a sticker is attached to the part of the
windshield in front of the front camera.

Close the hood, remove the sticker, etc. to
clear the obstruction.

When “Pre-Collision System Unavailable” is
displayed.

Check whether there is attached materials
on the radar sensor and radar sensor cover,
and if there is, remove it.

Situation

4-5. Using the driving support systems

The system can detect the following:



Vehicles



Bicyclists



Pedestrians

■

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.

■

Suspension control (if equipped)

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



P.266) will control the damp-

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

PCS (Pre-Collision System)

The pre-collision system uses a
radar sensor and front camera to
detect objects (



P.204) in front of

the vehicle. When the system
determines that the possibility of a
frontal collision with an object 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 an object is extremely
high, the brakes are automatically
applied to help avoid the collision or
help reduce the impact of the colli-
sion.

The pre-collision system can be dis-
abled/enabled and the warning tim-
ing can be changed. (

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.208

• Conditions under which the system

may not operate properly:



P.209

●

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.

■

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 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

LTA (Lane Tracing Assist)

When driving on highways and
freeways with white (yellow) lane
lines, this function alerts the driver
when the vehicle might depart from
its lane or course

and provides

assistance by operating the steer-
ing wheel to keep the vehicle in its
lane or course

. Furthermore, the

system provides steering assistance
when dynamic radar cruise control
with full-speed range is operating
to keep the vehicle in its lane.

The LTA system recognizes white
(yellow) lane lines or a course

using the front camera. Addition-
ally, it detects preceding vehicles
using the front camera and radar.

: Boundary between asphalt and the

side of the road, such as grass, soil, or
a curb

WARNING

■

Before using LTA system

●

Do not rely solely upon the LTA sys-

tem. The LTA system does not auto-

matically drive the vehicle or reduce

the amount of attention that must be

paid to the area in front of the vehicle.

The driver must always assume full

responsibility for driving safely by pay-

ing careful attention to the surround-

ing conditions and operating the

steering wheel to correct the path of

the vehicle. Also, the driver must take

adequate breaks when fatigued, such

as from driving for a long period of

time.

●

Failure to perform appropriate driving

operations and pay careful attention

may lead to an accident, resulting in

death or serious injury.

●

When not using the LTA system, use

the LTA switch to turn the system off.

■

Situations unsuitable for LTA system

In the following situations, use the LTA

switch to turn the system off. Failure to do

so may lead to an accident, resulting in
