You can flash the high beams with the 
headlights on or off.
When any of the following conditions is 
met, while the headlights (low beam) 
are on, the cornering lights will addi-
tionally turn on and light up the direc-
tion of movement for the vehicle. This is 
to ensure excellent visibility when 
either driving at intersections or park-
ing at night.
The steering wheel is operated
 The turn signal lever is operated
 The shift position is in R (both left 
and right side cornering lights)
■Cornering light control
●The lights illuminate when the vehicle  speed is approximately 19 mph (30 
km/h) or less. However,
 the lights turn off 
when the vehicle speed increases to 
approximately 22 mph (35 km/h) or 
more.
●After the lights remain illuminated for 30 
minutes, they automatically turn off.

Driving
●House 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.
●The 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
●The high beam may be turned on or off 
when the driver does not expect it.
●Bicycles or similar objects may not be 
detected.
●In the situations show n 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.
• Surrounding brightness levels are equal  to those of headlights, tail lights or fog 
lights.
• Vehicles ahead have headlights or tail 
lights that are either switched off, dirty, 
changing color, or have improperly 
adjusted aim.
• 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 tracks 
etc.). • When frequently and repeatedly taking 
curves or driving on a winding road.
• There is a highly re flective object ahead 
of the vehicle, such as a sign or a mirror.
• The vehicle’s headlights are damaged or  dirty.
• The vehicle is listing or titling, due to a flat  tire, a trailer being towed etc.
• The driver believes that the high beam 
may be causing problems or distress to 
other drivers or pedestrians nearby.
■Temporarily lowering  sensor sensitivity
The sensitivity of the  sensor can be tempo-
rarily lowered.
1 Turn the engine switch off while the fol-
lowing conditions are met.
• The headlight swit ch is in   or  .
• The headlight switch  lever is in low beam 
position.
• Automatic High Be am switch is on.
2 Turn the engine switch to ON.
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.

Driving
When the windshield wipers are not 
being used, they retract to below the 
hood. To enable the windshield wipers 
to be lifted when parking in cold condi-
tions or when replacing a windshield 
wiper insert, change the rest position of 
the windshield wipers to the service 
position using the wiper lever.
■Raising the wipers to the service 
position
Within approximately 45 seconds of 
turning the engine switch off, move the 
wiper lever to the   position and 
hold it for approximately 2 seconds or 
more.
The wipers will move to the service posi-
tion.
■Lifting the windshield wipers
While holding the hook portion   of 
the wiper arm, lift the windshield wiper 
from the windshield.
WARNING
■Caution regarding the use of wind-
shield wipers in “AUTO” mode
The windshield wipers may operate 
unexpectedly if the sensor is touched or 
the windshield is subject to vibration in 
“AUTO” mode. Take care that your fin-
gers or anything else do not become 
caught in the windshield wipers.
■Caution regarding the use of washer 
fluid
When it is cold, do not use the washer 
fluid until the windshield becomes warm. 
The fluid may freeze on the windshield 
and cause low visibility. This may lead to 
an accident, resulting in death or serious 
injury.
NOTICE
■When there is no washer fluid spray 
from the nozzle
Damage to the washer fluid pump may 
be caused if the lever is pulled toward 
you and held continually.
■When a nozzle becomes blocked
In this case, contact your Lexus dealer. 
Do not try to clear it with a pin or other 
object. The nozzle will be damaged.

WARNING
■Limitations of the pre-collision sys-
tem
●The driver is solely responsible for safe 
driving. Always drive safely, taking 
care to observe your surroundings. 
Do not use the pre-collision system 
instead of normal braking operations 
under any circumstances. This system 
will not prevent collisions or lessen col-
lision damage or injury in every situa-
tion. Do not overly rely on this system. 
Failure to do so may lead to an acci-
dent, resulting in death or serious 
injury.
●Although 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.182
• Conditions under which the system  may not operate properly:  P.184
●Do 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.
■Pre-collision braking
●When the pre-collision braking func-
tion is operating, a large amount of 
braking force will be applied.
●If 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.
●The 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.
●In 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.
●If the brake pedal is being depressed, 
the system may determine that the 
driver is taking evasive action and pos-
sibly delay the operat ion timing of the 
pre-collision braking function.
■When to disable the pre-collision sys-
tem
In the following situations, disable the 
system, as it may not operate properly, 
possibly leading to an accident resulting 
in death or serious injury:
●When the vehicle is being towed
●When your vehicle is towing another 
vehicle
●When transporting the vehicle via 
truck, boat, train or similar means of 
transportation
●When the vehicle is raised on a lift with 
the engine running and the tires are 
allowed to rotate freely
●When inspecting the vehicle using a 
drum tester such as a chassis dyna-
mometer or speedometer tester, or 
when using an on vehicle wheel bal-
ancer
●When a strong impact is applied to the 
front bumper or front grille, due to an 
accident or other reasons 

1844-5. Using the driving support systems
road or a wall that may be mistaken for a 
vehicle or pedestrian
• When driving near an  object that reflects 
radio waves, such as a large truck or 
guardrail
• When driving near a TV tower, broad-
casting station, electric power plant, or 
other location where  strong radio waves 
or electrical noise may be present
■Situations in which the system may not 
operate properly
●In some situations such as the following, a 
vehicle may not be detected by the radar 
sensor and front camera, preventing the 
system from operating properly:
• If an oncoming vehicle is approaching  your vehicle
• If a vehicle ahead is a motorcycle or bicy-
cle
• When approaching the side or front of a  vehicle
• If a preceding vehicle has a small rear  end, such as an unloaded truck
• If a preceding vehicle has a low rear end, 
such as a low bed trailer
• If a vehicle ahead is carrying a load which  protrudes past its rear bumper
• If a vehicle ahead has extremely high  ground clearance
• If a vehicle ahead is irregularly shaped,  such as a tractor or side car
• If the sun or other light is shining directly 
on a vehicle ahead
• If a vehicle cuts in front of your vehicle or  emerges from beside a vehicle
• If a vehicle ahead makes an abrupt  maneuver (such as sudden swerving, 
acceleration or deceleration)
• When suddenly cutting behind a preced- ing vehicle
• When a vehicle ahead is not directly in  front of your vehicle
• When driving in incl ement weather such 
as heavy rain, fog, snow or a sandstorm
• When the vehicle is hit by water, snow, 
dust, etc. from a vehicle ahead
• When driving through steam or smoke
• When driving in a place where the sur- rounding brightness changes suddenly, 
such as at the entrance or exit of a tunnel
• When a very bright light, such as the sun 
or the headlights of oncoming traffic, 
shines directly into the front camera
• When the surrounding area is dim, such 
as at dawn or dusk, or while at night or in 
a tunnel
• After the engine has started the vehicle 
has not been driven for a certain amount 
of time
• While making a left/right turn and for a 
few seconds after making a left/right turn
• While driving on a curve and for a few  seconds after driving on a curve
• If your vehicle is skidding
• If the front of the vehicle is raised or low- ered
• If the wheels are misaligned
• If a wiper blade is blocking the front cam- era 

1964-5. Using the driving support systems
This mode employs a radar sensor to detect the presence of vehicles up to approx-
imately 328 ft. (100 m) ahead, determines the current vehicle-to-vehicle following 
distance, and operates to maintain a suitable following distance from the vehicle 
ahead.
Note that vehicle-to-vehicle distance will close in when traveling on long downhill slopes.
Example of constant speed cruising
When there are no vehicles ahead
The vehicle travels at the speed set by the driver. The desired vehicle-to-vehicle distance 
can also be set by operating the ve hicle-to-vehicle distance switch.
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 this 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 th e system cannot decelerate sufficiently to 
prevent your vehicle from closing in on the vehicle ahead. 
When the vehicle ahead of you stops, your vehi cle 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 will  resume follow-up cruising.

2064-5. Using the driving support systems
■If “Clean Parking Assist Sensor” is dis-
played on the multi-information display
A sensor may be dirty or covered with snow 
or ice. In such cases,  if it is removed from 
the sensor, the system should return to nor-
mal.
Also, due to the sensor being frozen at low 
temperatures, a malfunction display may 
appear or an obstacle may not be detected. 
If the sensor thaws out, the system should 
return to normal.
■If “Parking Assist Malfunction” or 
“Parking Assist Malfunction Visit Your 
Dealer” is displayed on the multi-infor-
mation display
There is a malfunction and the device may 
not be working properly.
Have the vehicle inspected by your Lexus 
dealer.
■Sensor detectio n information
●The sensor’s detection areas are limited 
to the areas around the vehicle’s front 
and rear bumpers.
●Certain vehicle conditions and the sur-
rounding environment may affect the 
ability of the sensor to correctly detect 
obstacles. Particular instances where this 
may occur are listed below.
• There is dirt, snow or ice on the sensor. 
(Wiping the sensors will resolve this 
problem.)
• The sensor is frozen. (Thawing the area 
will resolve this problem.) 
In especially cold weather, if a sensor is 
frozen the screen may show an abnormal 
display, or obstacles may not be 
detected.
• The sensor is covered in any way.
• The vehicle is leaning considerably to 
one side.
• On an extremely bumpy road, on an 
incline, on gravel, or on grass.
• The vicinity of the vehicle is noisy due to  vehicle horns, motorcycle engines, air 
brakes of large vehicles, or other loud 
noises producing ultrasonic waves.
• There is another vehicle equipped with  parking assist sensor in the vicinity.
• The sensor is coated with a sheet of spray  or heavy rain.
• The vehicle is equipped with a fender  pole or wireless antenna.
• Towing eyelets are installed.
• The bumper or sensor receives a strong  impact.
• The vehicle is approaching a tall or  curved curb.
• In harsh sunlight or intense cold weather.
• The area directly under the bumpers is  not detected.
• If obstacles draw too  close to the sensor.
• A non-genuine Lexus suspension (low- ered suspension etc.) is installed.
• People may not be detected if they are  wearing certain types of clothing.
In addition to the examples above, there are 
instances in which, be cause of their shape, 
signs and other objects may be judged by 
the sensor to be closer than they are.
●The shape of the obstacle may prevent 
the sensor from detecting it. Pay particu-
lar attention to the following obstacles:
• Wires, fences, ropes, etc.
• Cotton, snow and other materials that  absorb sound waves
• Sharply-angled objects
• Low obstacles
• Tall obstacles with upper sections pro- jecting outwards in the direction of your 
vehicle
●The following situations may occur 
during use.
• Depending on the shape of the obstacle  and other factors, the detection distance 
may shorten, or detection may be impos-
sible.
• Obstacles may not be detected if they  are too close to the sensor.
• There will be a short delay between  obstacle detection and display. Even at 
slow speeds, there is  a possibility that the 
obstacle will come within the sensor’s 
detection areas befo re the display is 
shown and the warning beep sounds.
• Thin posts or object s lower than the sen-
sor may not be detected when 
approached, even if they have been 
detected once.
• It might be difficult to hear beeps due to  the volume of the audio system or air flow 
noise of the air conditioning system.
• It might be difficult to hear beeps due to  the sounds of other systems.
