226 4-5. Using the driving support systems
LS500_OM_(U)_1810 WARNING■
Before using LTA system
Do not rely solely upon the LTA system.
The LTA system does not automatically
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 driv-
ing safely by paying careful attention to
the surrounding conditions and operat-
ing 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 acc ident, 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.
●

worn, or when the tire inflation pres-
sure is low.
●
When tires of a size other than speci-
fied are installed. ●
Vehicle is driven in traffic lanes other
than that highways and freeways. ●
During emergency towing. ■
Situations in whic h the lane change
assist function should not be used ●
When driving on a one lane road or
road without lane markers ●
When there is no broken white line
between your vehicle and the lane
toward which the turn signal is oper-
ated ■
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,

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 vehicle
may depart from its la ne. Drive safely by
always paying careful attention to your

LS500_OM_(U)_1810 4
Driving has become avoidable with normal brake
operation.
• The static object is no longer 6 to 13 ft. (2
to 4 m) away from the vehicle or in the
traveling direction of the vehicle.●
Brake control
• The Parking Support Brake is disabled.
• Approximately 2 seconds have elapsed
since the vehicle was stopped by brake
control.
• The brake pedal is depressed after the
vehicle is stopped by brake control.
• The static object is no longer 6 to 13 ft. (2
to 4 m) away from the vehicle or in the
traveling direction of the vehicle.■
Re-enabling the Parking Support Brake
function (static objects)
 P.275■
Detection range of the Parking Support
Brake function (static objects)
The detection range of the Parking Support
Brake function (static objects) differs from
the detection range of the intuitive parking
assist. (  P.261) Therefore, even if the intui-
tive parking assist de tects an object and
provides a warning, the Parking Support
Brake function (static objects) may not start
operating. ■
Objects that the Parking Support Brake
function (static obje cts) may not detect
The sensors may not be able to detect cer-
tain objects, such as the following: ●
Pedestrian●
Cotton cloth, snow, and other materials
that are poor reflectors of ultrasonic
waves●
Objects which are not perpendicular to
the ground, are not perpendicular to the
traveling direction of the vehicle, are
uneven or are waving
●
Low objects
●
Thin objects such as wires, fences, ropes
and signposts
●
Objects that are extremely close to the
bumper
●
Sharply-angled objects
●
Tall objects with upper sections project-
ing outwards in the direction of your vehi- cle ■
Intuitive parking assist buzzer
Regardless of whether the intuitive parking
assist system is enabled or not (  P.258), if
the Parking Support Brake function (static
objects) is enabled (  P.271), the front or
rear sensors detect an object and brake
control is performed, the intuitive parking
assist buzzer will sound to notify the driver
of the approximate distance to the object. ■
Situations in which the Parking Support
Brake function (static objects) may
operate even if there is no possibility of a
collision
In some situations, such as the following, the
Parking Support Brake function (static
objects) may operate even though there is
no possibility of a collision. ●
Vehicle surroundings
• When driving on a narrow road
• When driving on a gravel road or in an
area with tall grass
• When driving toward a banner, flag,
low-hanging branch or boom barrier
(such as those used at railroad crossings,
toll gates and parking lots)
• When driving on a narrow path sur-
rounded by a structure, such as in a tun-
