WARNING
QBefore using LTA system
ODo 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.
OFailure to perform appropriate driving
operations and pay careful attention
may lead to an accident, resulting in
death or serious injury.
QSituations 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.
OVehicle is driven on a road surface
which is slippery due to rainy weather,
fallen snow, freezing, etc.
OVehicle is driven on a snow-covered
road.
OWhite (yellow) lines are difficult to see
due to rain, snow, fog, dust, etc.
OVehicle is driven in a temporary lane
or restricted lane due to construction
work.
OVehicle is driven in a construction
zone.
OA spare tire, tire chains, etc. are
equipped.
OWhen the tires have been excessively
worn, or when the tire inflation pres-
sure is low.
ODuring emergency towing
QPreventing LTA system malfunctions
and operations performed by mistake
ODo not modify the headlights or place
stickers, etc. on the surface of the
lights.
ODo not modify the suspension etc. If
the suspension etc. needs to be
replaced, contact your Lexus dealer.
ODo not install or place anything on the
hood or grille. Also, do not install a
grille guard (bull bars, kangaroo bar,
etc.).
OIf your windshield needs repairs, con-
tact your Lexus dealer.
QConditions 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.
OWhen the follow-up cruising display is
displayed ( P.197) and the preced-
ing vehicle changes lanes. (Your vehi-
cle may follow the preceding vehicle
and also change lanes.)
OWhen the follow-up cruising display is
displayed ( P.197) and the preced-
ing vehicle is swaying. (Your vehicle
may sway accordingly and depart from
the lane.)

2064-5. Using the driving support systems
This mode employs a radar to detect the presence of vehicles up to approximately
328 ft. (100 m) ahead, determines the current vehicle-to-vehicle following dis-
tance, and operates to maintain a suitable following distance from the vehicle
ahead. The desired vehicle-to-vehicle distance can also be set by operating the
vehicle-to-vehicle distance switch.
When driving on down hill slopes, the vehicle-to-vehicle distance may become shorter.
Example of constant speed cruising
When there are no vehicles ahead
WARNING
OAt entrances to freeways and high-
ways
OWhen weather conditions are bad
enough that they may prevent the sen-
sors from detecting correctly (fog,
snow, sandstorm, heavy rain, etc.)
OWhen there is rain, snow, etc. on the
front surface of the radar or front cam-
era
OIn traffic conditions that require fre-
quent repeated acceleration and
deceleration

WARNING
QCautions regarding the use of the
system
Do not overly rely on the system, as
doing so may lead to an accident.
Always drive while checking the safety of
the surroundings of the vehicle.
Depending on the vehicle and road con-
ditions, weather, etc., the system may not
operate.
The detection capabilities of sensors and
radars are limited. Always drive while
checking the safety of the surroundings
of the vehicle.
OThe driver is solely responsible for safe
driving. Always drive carefully, taking
care to observe your surroundings.
The Parking Support Brake system is
designed to provide support to lessen
the severity of collisions. However, it
may not operate in some situations.
OThe Parking Support Brake system is
not designed to stop the vehicle com-
pletely. Additionally, even if the system
has stopped the vehicle, it is necessary
to depress the brake pedal immedi-
ately as brake control will be canceled
after approximately 2 seconds.
OIt is extremely dangerous to check the
system operations by intentionally
driving the vehicle in to the direction of
a wall, etc. Never attempt such actions.
QWhen to disable the Parking Support
Brake
In the following situations, disable the
Parking Support Brake as the system
may operate even though there is no
possibility of a collision.
