Drive assist system WARNING■
Lexus Safety System + A
The Lexus Safety System + A is designed
to operate under the assumption that the
driver will drive safely , and is designed to
help reduce the impact to the occupants
and the vehicle in the case of a collision
or assist the driver in normal driving con-
ditions.
As there is a limit to the degree of recog-
nition accuracy and control performance
that this system can provide, do not
overly rely on this system. The driver is
always responsible for paying attention
to the vehicle’s surroundings and driving
safely.

WARNING
■
To avoid malfunction of the radar sen-
sor
Observe the following precautions.
Otherwise, the radar sensor may not
operate properly, possibly leading to an
accident resulting in death or serious
injury. A

210 4-5. Using the driving support systems
LS500_OM_(U)_1810 a vehicle, pedestrian or bicyclist may not be
detected depending on the surrounding
brightness and the motion, posture, and
angle of the person, preventing the system
from operating properly. (  P.212)
The illustration shows an image of vehicles,
pedestrians and bicyclists.
■
Cancelation of pre-collision braking
and active steering assist
If either of the following occur while the
pre-collision braking function is operating, it
will be canceled: ●
The accelerator pedal is depressed
strongly.●
The steering wheel is turned sharply or
abruptly.■
Conditions under which the system may
operate even if there is no possibility of a
collision●
In some situations such as the following,
the system may determine that there is a
possibility of a frontal collision and oper-
ate.
• When passing a vehicle, pedestrian or
bicyclist
• When changing lane s while overtaking a
vehicle, pedestrian or bicyclist
• When approaching a vehicle, pedestrian
or bicyclist in an adjacent lane or on the
roadside, such as when changing the
course of travel or driving on a winding
road
• When rapidly closing on a vehicle, pedestrian, bicyclist, etc.
• When approaching objects on the road-
side, such as vehicle, pedestrian, bicyclist,
guardrails, traffic signs, utility poles, street
lights, trees, walls, etc.
• When there is a vehicle, pedestrian, bicy-
clist or object by the roadside at the
entrance of a curve
• When there are patterns or paint in front
of your vehicle that may be mistaken for a
vehicle, pedestrian or bicyclist
• When the front of your vehicle is hit by
water, snow, dust, etc.
• When overtaking a vehicle, pedestrian or
bicyclist that is changing lanes or making
a right/left turn
• When passing a vehicle, pedestrian or
bicyclist in an onco ming lane that is
stopped to make a right/left turn
• When a vehicle, pedestrian or bicyclist
approaches very close and then stops
before entering the pa th of your vehicle
• If the front of your vehicle is raised or low-
ered, such as when on an uneven or
undulating road surface

214 4-5. Using the driving support systems
LS500_OM_(U)_1810 ●
In some situations, such as the following,
the sensors may not detect the lane lines
or a safe space the vehicle can be steered
into, preventing the ac tive steering assist
from operating properly:
• When the white (yellow) lane lines are
difficult to see, such as when they are
faint, diverging/merging, or a shadow is
cast upon them
• When the lane is more wide or narrow
than normal
• When there is a light and dark pattern on
the road surface, such as due to road
repairs
• If the system determines that a collision
can be avoided by only using the brakes
• When a pedestrian is detected near the
centerline of the vehicle●
In some situations such as the following,
sufficient braking force or steering force
may not be obtained, preventing the sys-
tem 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,
improper tire inflation pressure, etc.)
• When the vehicle is being driven on a
gravel road or other slippery surface
• If there are deep ruts in the road
• When driving on a slope
• When driving on a horizontally slanted
road●
Some guardrails, such as the following,
may not be detected by the sensors, pre-
venting the system from operating prop-
erly:
• Guardrails which are less than approxi-
mately 1.9 ft. (60 cm) tall
• Short guardrails
• Irregularly-shaped guardrails (wire cable
guardrails, guardrails made of thin poles,
etc.)
• Guardrails which are not illuminated by
the headlights at night, in a tunnel, etc.
• Guardrails which appear to be nearly the
same color or brig htness as their sur-
roundings
• Guardrails which appear to be nearly the
same shape as their surroundings (walls,
etc.) • Guardrails which are over a metal object
(manhole cover, steel plate, etc.)
• Guardrails which are hidden behind thick
grass
• Guardrails which are extremely close to
the side of the vehicle (outside rear view
mirror, etc.)
• Curved guardrails or guardrails at the
entrance of a curve ●
In some situations su ch as the following,
the system may detect a pedestrian and
display a warning on the head-up display,
even though no pedestrian exists:
• If the front of the vehicle is raised or low-
ered, such as when the road surface is
uneven or undulating (due to ruts, etc.)
• When driving on a slope
• When driving on a horizontally slanted
road
• If the driver’s posture (driver seat posi-
tion) is extreme, such as excessively
reclined
• If the head-up display position is set
extremely high ■
If VSC is disabled ●
If VSC is disabled (  P.294), the pre-col-
lision brake assist and pre-collision brak-
ing functions are also disabled. ●
The PCS warning light will turn on and
“VSC Turned Off Pre-Collision Brake
System Unavailable” will be displayed on
the multi-information display.

The system may be temporarily unavailable
or may be malfunctioning.
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 and
when changing lanes (vehicles with
Lexus Safety System + A).
The LTA system recognizes white
(yellow) lane lines or a course *

using the front camera. Addition-
ally, it detects preceding and sur-
rounding vehicles (vehicles with
Lexus Safety System + A) using the
front camera and radar. *
