Each function is operational at the following speed

●

Pre-collision warning

●

Pre-collision brake assist

●

Pre-collision braking

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

●

If the shift lever is in R

●

When the VSC OFF indicator is illuminated (only the pre-collision warning function will

be operational)

■

Object detection function

The system detects objects based on their

size, profile, motion, etc. However, an

object may not be detected depending on

the surrounding brightness and the motion,

posture, and angle of the detected object,

preventing the system from operating

properly. (

it will be canceled:

●

The accelerator pedal is depressed

strongly.

●

The steering wheel is turned sharply or

abruptly.

■

the system may determine that there is a

possibility of a frontal collision and oper-

ate.

detectable object, etc.

• When approaching a detectable object

in an adjacent lane or on the roadside,

such as when changing the course of

travel or driving on a winding road

side, such as detectable objects, guard-

rails, utility poles, trees, or walls

■

Situations in which the system may not

operate properly

●

In some situations such as the following,

an object may not be detected by the

radar sensor and front camera, prevent-

ing the system from operating properly:

• When a detectable object is approaching

your vehicle

maneuver (such as sudden swerving,

acceleration or deceleration)

• When your vehicle approaches a detect-

able object rapidly

in front of your vehicle

• When a detectable object is near a wall,

fence, guardrail, manhole cover, vehicle,

steel plate on the road, etc.

• When a detectable object is under a

structure

water, snow, dust, etc.

• When a very bright light ahead, such as

the sun or the headlights of oncoming

traffic, shines directly into the front cam-

era

• When approaching the side or front of a

vehicle ahead

• If a vehicle ahead is a motorcycle

• If a vehicle ahead is narrow, such as a

personal mobility vehicle

bicycle ridden by more than one person,

or a uniquely shaped bicycle (bicycle with

a child seat, tandem bicycle, etc.)

• If a pedestrian/or the riding height of a

bicyclist ahead is shorter than approxi-

mately 3.2 ft. (1 m) or taller than approxi-

mately 6.5 ft. (2 m)

In some situations such as the following,

sufficient braking force may not be

obtained, preventing the system from

performing properly:

• If the braking functions cannot operate to

their full extent, such as when the brake

parts are extremely cold, extremely hot,

or wet

• If the vehicle is not properly maintained

(brakes or tires are excessively worn,

The PCS warning light will turn on and

“VSC Turned OFF Pre-Collision Brake

System Unavailable” will be displayed on

the multi-information display.

LTA (Lane Tracing Assist)

While driving on a road with clear
white (yellow) lane lines, the LTA
system warns the driver if the vehi-
cle may deviate from the current
lane or course

, and also can

slightly operate the steering wheel
to help avoid deviation from the
lane or course

. Also, while the

dynamic radar cruise control with
full-speed range is operating, this
system will operate the steering
wheel to maintain the vehicle’s lane
position.

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

death or serious injury.

●

Vehicle is driven on a road surface

which is slippery due to rainy weather,

fallen snow, freezing, etc.

●

Vehicle is driven on a snow-covered

road.

●

White (yellow) lines are difficult to see

due to rain, snow, fog, dust, etc.

●

Vehicle is driven in a temporary lane

or restricted lane due to construction

work.

●

Vehicle is driven in a construction

zone.

●

A spare tire, tire chains, etc. are

equipped.

●

When the tires have been excessively

worn, or when the tire inflation pres-

sure is low.

WARNING

●

During emergency towing

■

Preventing LTA system malfunctions

and operations performed by mistake

●

Do not modify the headlights or place

stickers, etc. on the surface of the

lights.

●

Do not modify the suspension etc. If

the suspension etc. needs to be

replaced, contact your Lexus dealer.

●

Do not install or place anything on the

hood or grille. Also, do not install a

grille guard (bull bars, kangaroo bar,

etc.).

●

If your windshield needs repairs, con-

tact your Lexus dealer.

■

Conditions in which functions may

not operate properly

In the following situations, the functions

may not operate properly and the vehi-

cle may depart from its lane. Drive safely

by always paying careful attention to

your surroundings and operate the

steering wheel to correct the path of the

vehicle without relying solely on the func-

tions.

P.195) and the preced-

ing vehicle changes lanes. (Your vehi-

cle may follow the preceding vehicle

and also change lanes.)

ing vehicle is being driven extremely

close to the left/right lane line. (Your

vehicle may follow the preceding vehi-

cle and depart from the lane.)

●

Vehicle is being driven around a sharp

curve.

●

Objects or patterns that could be mis-

taken for white (yellow) lines are pres-

ent on the side of the road (guardrails,

reflective poles, etc.).

●

Vehicle is driven where the road

diverges, merges, etc.

Lane departure alert function

When the system determines that the
vehicle might depart from its lane or
course

, a warning is displayed on the

multi-information display, and either a
warning buzzer will sound or the steer-
ing wheel will vibrate to alert the driver.

When the warning buzzer sounds or the
steering wheel vibrates, check the area
around your vehicle and carefully operate
the steering wheel to move the vehicle
back to the center of the lane.
Vehicle with BSM: When the system
determines that the vehicle might depart
from its lane and that the possibility of a
collision with an overtaking vehicle in the
adjacent lane is high, the lane departure

■

Steering assist function

When the system determines that the
vehicle might depart from its lane or
course

, the system provides assis-

tance as necessary by operating the
steering wheel in small amounts for a
short period of time to keep the vehicle

If the system detects that the steering
wheel has not been operated for a fixed
amount of time or the steering wheel is not
being firmly gripped, a warning is dis-
played on the multi-information display
and the function is temporarily canceled.
