Driving
OHouse lights, street lights, traffic signals,
and illuminated billboards or signs may
cause the high beam to switch to the low
beams, or the low beams to remain on.
OThe following factors may affect the
amount of time taken to turn the high
beam on or off:
• The brightness of headlights, fog lights,
and tail lights of vehicles ahead
• The movement and direction of vehicles ahead
• When a vehicle ahead only has opera- tional lights on one side
• When a vehicle ahead is a two-wheeled
vehicle
• The condition of the road (gradient, curve, condition of the road surface etc.)
• The number of passengers and amount of luggage
OThe high beam may be turned on or off
when the driver does not expect it.
OBicycles or similar objects may not be
detected.
OIn the situations shown below, the system
may not be able to accurately detect sur-
rounding brightness levels. This may
cause the low beams to remain on or the
high beams to cause problems for pedes-
trians, vehicles ahead or other parties. In
these cases, manually switch between the
high and low beams.
• In bad weather (rain, snow, fog, sand-
storms etc.)
• The windshield is obscured by fog, mist, ice, dirt etc.
• The windshield is cracked or damaged
• The front camera is deformed or dirty
• When the temperature of the front cam- era is extremely high
• Surrounding brightness levels are equal to those of headlights, tail lights or fog
lights
• When headlights or tail lights of vehicles ahead are turned off, dirty, changing
color, or not aimed properly
• When the vehicle is hit by water, snow,
dust, etc. from a preceding vehicle
• When driving through an area of inter- mittently changing brightness and dark-
ness
• When frequently and repeatedly driving ascending/descending roads, or roads with rough, bumpy or uneven surfaces
(such as stone-paved roads, gravel roads
etc.)
• When frequently and repeatedly taking curves or driving on a winding road
• There is a highly reflective object ahead
of the vehicle, such as a sign or a mirror
• The back of a vehicle ahead is highly reflective, such as a container on a truck.
• The vehicle’s headlights are damaged or dirty
• The vehicle is listing or tilting, due to a flat
tire, a trailer being towed etc.
• The high beam and low beam are repeat- edly being switched between in an
abnormal manner
• The driver believes that the high beam may be causing problems or distress to
other drivers or pedestrians nearby
QTemporarily lowering sensor sensitivity
The sensitivity of the sensor can be tempo-
rarily lowered.
1 Turn the power switch off while the fol-
lowing conditions are met.
• The headlight switch is in or .
• The headlight switch lever is in low beam position.
• Automatic High Beam switch is on.
2 Turn the power switch to ON mode.
3 Within 60 seconds after 2, repeat pull-
ing the headlight switch lever to the
original position then pushing it to the
high beam position quickly 10 times,
then leave the lever in high beam posi-
tion.
4 If the sensitivity is changed, the Auto-
matic High Beam indicator turns on and
off 3 times.
Automatic High Beam (headlights) may
turn on even the vehicle is stopped.

WARNING
OAlthough this system is designed to
help avoid a collision or help reduce
the impact of the collision, its effective-
ness may change according to various
conditions, therefore the system may
not always be able to achieve the same
level of performance.
Read the following conditions care-
fully. Do not overly rely on this system
and always drive carefully.
• Conditions under which the system may operate even if there is no possi-
bility of a collision: P.188
• Conditions under which the system may not operate properly: P.190
ODo not attempt to test the operation of
the pre-collision system yourself.
Depending on the objects used for
testing (dummies, cardboard objects
imitating detectable objects, etc.), the
system may not operate properly, pos-
sibly leading to an accident.
QPre-collision braking
OWhen the pre-collision braking func-
tion is operating, a large amount of
braking force will be applied.
OIf the vehicle is stopped by the opera-
tion of the pre-collision braking func-
tion, the pre-collision braking function
operation will be canceled after
approximately 2 seconds.
Depress the brake pedal as necessary.
OThe pre-collision braking function may
not operate if certain operations are
performed by the driver. If the acceler-
ator pedal is being depressed strongly
or the steering wheel is being turned,
the system may determine that the
driver is taking evasive action and pos-
sibly prevent the pre-collision braking
function from operating.
OIn some situations, while the pre-colli-
sion braking function is operating,
operation of the function may be can-
celed if the accelerator pedal is
depressed strongly or the steering
wheel is turned and the system deter-
mines that the driver is taking evasive
action.
OIf the brake pedal is being depressed,
the system may determine that the
driver is taking ev asive action and pos-
sibly delay the operation timing of the
pre-collision braking function.
QEmergency steering assist
OAs emergency steering assist opera-
tion will be canceled when the system
determines that lane departure pre-
vention function has been completed.
OEmergency steering assist may not
operate or may be cancel in the fol-
lowing cases as the system may deter-
mine the driver is taking actions.
• If the accelerator pedal is being depressed strongly, the steering wheel
is being operated sharply, the brake
pedal is being depressed or the turn
signal lever is bein g operated. In this
case, the system may determine that
the driver is taking evasive action and
the emergency steering assist may not
operate.
• In some situations, while the emer- gency steering assist is operating,
operation of the function may be can-
celed if the accelerator pedal is
depressed strongly, the steering wheel
is operated sharply or the brake pedal
is being depressed and the system
determines that the driver is taking
evasive action.
• When the emergency steering assist is operating, if the steering wheel is held
firmly or is operated in the opposite
direction to that which the system is
generating torque, the function may
be canceled.

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.)

QLane departure alert function
When the system determines that the
vehicle might depart from its lane or
course
*, a warning is displayed on the
multi-information display, and either a
warning buzzer will sound or the steer-
ing wheel will vibrate to alert the driver.
When the warning buzzer sounds or the
steering wheel vibrates, check the area
around your vehicle and carefully operate
the steering wheel to move the vehicle
back to the center of the lane.
When the system determines that the vehi-
cle might depart from its lane and that the
possibility of a collision with an overtaking
vehicle in the adjacent lane is high, the lane
departure alert will operate even if the turn
signals are operating.

Driving
The vehicle travels at the speed set by the driver.
Example of deceleration cruising and follow-up cruising
When a preceding vehicle driving slower than the set speed appears
When a vehicle is detected running ahead of you, the system automatically decelerates
your vehicle. When a greater reduction in vehicle speed is necessary, the system applies
the brakes (the stop lights will come on at th is time). The system will respond to changes in
the speed of the vehicle ahead in order to maintain the vehicle-to-vehicle distance set by
the driver. Approach warning warns you when the system cannot decelerate sufficiently to
prevent your vehicle from closing in on the vehicle ahead.
When the vehicle ahead of you stops, your vehicl e will also stop (vehicle is stopped by sys-
tem control). After the vehicle ahead starts off, pressing the “+RES” switch or depressing
the accelerator pedal (start-off operation) will resume follow-up cruising. If the start-off
operation is not performed, system contro l continues to keep your vehicle stopped.
When the turn signal lever is operated and your vehicle moves to an overtaking lane while
driving at 50 mph (80 km/h) or more, the vehicle will accelerate to help to overtake a
passing vehicle.
The system’s identification of what is an overtaking lane may be determined solely based on
the location of the steering wheel in the vehicl e (left side driver position versus right side
driver position.) If the vehicle is driven to a region where the overtaking lane is on a differ-
ent side from where the vehicle is normally driven, the vehicle may accelerate when the
turn signal lever is operated in the opposite direction to the overtaking lane (e.g., if the
driver normally operates the vehicle in a region where the overtaking lane is to the right but
then drives to a region where the overtaking lane is to the left, the vehicle may accelerate
when the right turn signal is activated).
Example of acceleration
When there are no longer any preceding vehicles driving slower than the set
speed
The system accelerates until the set speed is reached. The system then returns to constant
speed cruising.
1 Press the cruise control main
switch to activate the cruise con-
trol.
Dynamic radar cruise control indicator will
come on and a message will be displayed
on the multi-information display. Press the
switch again to deactivate the cruise con-
trol. If the cruise control main switch is pressed
and held for 1.5 seconds or more, the sys-
tem turns on in constant speed control
mode. (
