Hands off steering wheel warning

In the following situations, a warning mes-

sage urging the driver to hold the steering

wheel and the symbol shown in the illustra-

tion are displayed on the multi-information

display to warn the driver. The warning

stops when the system determines that the

driver holds the steering wheel. Always

keep your hands on the steering wheel

when using this system, regardless of warn-

ings.
Depending on the vehicle condition and

road conditions, the warning may not oper-

ate. Also, if the system determines that the

vehicle is driving around a curve, warnings

will occur earlier than during straight-lane

driving.

If the driver continues to keep their hands
off of the steering wheel, the buzzer
sounds, the driver is warned and the func-

Have the vehicle inspected by any author-

ized Lexus retailer or Lexus authorized

repairer, or any reliable repairer.

●

“LTA Unavailable”

The system is temporarily canceled due to

a malfunction in a sensor other than the

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

, and also can slightly operate

the steering wheel to help avoid devia-
tion 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 (yel-
low) lane lines or a course

using the

front camera. Additionally, it detects
preceding vehicles using the front
camera and radar.

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.

■

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.

●

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 any authorized

Lexus retailer or Lexus authorized

repairer, or any reliable repairer.

●

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 any authorized Lexus retailer or

Lexus authorized repairer, or any relia-

ble repairer.

■

Conditions in which functions may

not operate properly

■

Lane centering function

This function is linked with dynamic
radar cruise control with full-speed
range and provides the required assis-
tance by operating the steering wheel
to keep the vehicle in its current lane.

When dynamic radar cruise control with
full-speed range is not operating, the lane
centering function does not operate.
In situations where the white (yellow) lane
lines are difficult to see or are not visible,
such as when in a traffic jam, this function
will operate to help follow a preceding
vehicle by monitoring the position of the
preceding vehicle.

Turning the LTA system on

Press the LTA switch.

When the LTA system will turn on, the LTA
indicator will illuminate and a message will
be displayed on the multi-information dis-

play.
Also, the lane centering function will
change between on/off each time the
switch is pressed.

Lane centering function off: “LTA Steering
Assist Active” is displayed.

: If equipped

The RSA system recognizes specific
road signs using the front camera

limit information is available) to provide
information to the driver via the display.

If the system judges that the vehicle is
being driven over the speed limit, per-
forming prohibited actions, etc.
according to the recognized road
signs, it notifies the driver through a
visual notification and notification
buzzer or steering wheel vibration.

When the front camera recognizes a
sign and/or information of a sign is
