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.

222 4-5. Using the driving support systems
LS500_OM_(U)_1810 • If the wheels are misaligned
• If a wiper blade is blocking the front cam-
era
• The vehicle is being driven at extremely
high speeds
• When driving on a hill
• If the radar sensor or front camera is mis-
aligned●
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,
improper tire inflation pressure, etc.)
• When the vehicle is being driven on a
gravel road or other slippery surface■
If VSC is disabled●
If VSC is disabled ( P.296), 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. *
: If equipped
When the system detects a vehicle
approaching from the left or right in
front of your vehicle when approaching
an intersection, a notification will be
displayed on the head-up display and
panoramic view monitor *
. *
: Refer to “NAVIGATION AND MULTI-
MEDIA SYSTEM OWNER’S MAN-
UAL”.
When the system determines that your
vehicle may be about to enter an inter-
section even though a vehicle is
approaching from the left or right in
front of your vehicle, a buzzer will
sound and a message will be displayed
on the multi-information display to
urge you to depress the brake pedal.
Head-up displayFCTA (Front Cross Traffic
Alert) *
When approaching an intersection
at low speed, the radar sensors on
the front side of the vehicle can
detect approaching vehicles to the
left and right of the front of the vehi-
cle. In this case, the head-up display
is used to inform the driver of
detected vehicles.

Driving WARNING■
Secondary Collision Brake
Do not overly rely on the Secondary Col-
lision Brake. This system is designed to
help reduce the possibility of further
damage due to a secondary collision,
however, that effect changes according
to various conditions. Overly relying on
the system may result in death or serious
injury. ■
Replacing tires
Make sure that all ti res are of the speci-
fied size, brand, tread pattern and total
load capacity. In addition, make sure that
the tires are inflated to the recom-
mended tire inflation pressure level.
The ABS, TRAC and VSC systems will
not function correctly if different tires are
installed on the vehicle.
Contact your Lexus dealer for further
information when replacing tires or
wheels. ■
Handling of tires and the suspension
Using tires with any kind of problem or
modifying the suspension will affect the
driving assist systems, and may cause a
system to malfunction.
