out using the headlights is detected.

●

House lights, street lights, traffic signals, 

and illuminated billboards or signs may 

cause the high beams 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 

beams 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 beams may be turned on or off 

when the driver does not expect it.

●

Bicycles or similar objects may not be 

detected.

●

In 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 camera 

sensor 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 

on ascending/descending roads, or 

roads with rough, bumpy or uneven sur-

faces (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 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, or are not aimed properly

• The vehicle is listing or titling due to a flat 

tire, a trailer being towed, etc.

• The high beams and low beams are 

repeatedly being switched between in an 

abnormal manner

• The driver believes that the high beams 

may be causing problems or distress to 

other drivers or pedestrians nearby

• The vehicle is used in a territory in which 

vehicles travel on the opposite side of the 

road of the country for which the vehicle 

is approved, for example using a vehicle 

designed for right-hand traffic in a left-

hand traffic territory, or vice versa.

Opening the fuel tank cap

Perform the following steps to open 
the fuel tank cap:

Before refueling the vehicle

WARNING

■

When refueling the vehicle

Observe the following precautions while 

refueling the vehicle. Failure to do so 

may result in death or serious injury.

●

After exiting the vehicle and before 

opening the fuel door, touch an 

unpainted metal surface to discharge 

any static electricity. It is important to 

discharge static electricity before refu-

eling because sparks resulting from 

static electricity can cause fuel vapors 

to ignite while refueling.

●

Always hold the grips on the fuel tank 

cap and turn it slowly to remove it.

A whooshing sound may be heard 

when the fuel tank cap is loosened. 

Wait until the sound cannot be heard 

before fully removing the cap. In hot 

weather, pressurized fuel may spray 

out of the filler neck and cause injury.

●

Do not allow anyone that has not dis-

charged static electricity from their 

body to come close to an open fuel 

tank.

●

Do not inhale vaporized fuel.

Fuel contains substances that are 

harmful if inhaled.

●

Do not smoke while refueling the vehi-

cle.

Doing so may cause the fuel to ignite 

and cause a fire.

●

Do not return to the vehicle or touch 

any person or object that is statically 

charged. This may cause static elec-

tricity to build up, resulting in a possi-

ble ignition hazard.

■

When refueling

Observe the following precautions to 

prevent fuel overflowing from the fuel 

tank:

●

Securely insert the fuel nozzle into the 

fuel filler neck.

●

Stop filling the tank after the fuel noz-

zle automatically clicks off.

●

Do not top off the fuel tank.

NOTICE

■

Refueling

Do not spill fuel during refueling.

Doing so may damage the vehicle, such 

as causing the emission control system to 

operate abnormally or damaging fuel 

system components or the vehicle’s 

painted surface.

■

If a warning message is displayed on the multi-information display

A system may be temporarily unavailable or there may be a malfunction in the system.

●

In the following situations, perform the actions specified in the table. When the normal operating 

conditions are detected, the message will disappear and the system will become operational.

If the message does not disappear, contact your Lexus dealer.

●

In the following situations, if the situation has changed (or the vehicle has been driven for some 

time) and the normal operating conditions are detected, the message will disappear and the sys-

tem will become operational.

If the message does not disappear, contact your Lexus dealer.

• When the temperature around the radar sensor is outside of the operational range, such as 

when the vehicle is in the sun or in an extremely cold environment

• When the front camera cannot detect objects in front of the vehicle, such as when driving in the 

dark, snow, or fog, or when bright lights are shining into the front camera

• Depending on the conditions in the vicinity of the vehicle, the radar may judge the surrounding 

environment can not be properly recognized. In that case, “Pre-Collision System Unavailable 

See Owner’s Manual” is displayed.

Situation

Actions

When the area around a camera is covered 
with dirt, moisture (fogged up, covered with 
condensation, ice, etc.), or other foreign 
matter

Using the wiper and A/C function, remove 
the dirt and other attached matter. 
(



P.388)

When the temperature around the front 
camera is outside of the operational range, 
such as when the vehicle is in the sun or in an 
extremely cold environment

If the front camera is hot, such as after the 
vehicle had been parked in the sun, use the 
air conditioning system to decrease the tem-
perature around the front camera.
If a sunshade was used when the vehicle was 
parked, depending on its type, the sunlight 
reflected from the surface of the sunshade 
may cause the temperature of the front cam-
era to become excessively high.

If the front camera is cold, such after the 
vehicle is parked in an extremely cold envi-
ronment, use the air conditioning system to 
increase the temperature around the front 
camera.

The area in front of the front camera is 
obstructed, such as when the hood is open 
or a sticker is attached to the part of the 
windshield in front of the front camera.

Close the hood, remove the sticker, etc. to 
clear the obstruction.

When “Pre-Collision System Radar In Self 
Calibration Unavailable See Owner’s Man-
ual” is displayed.

Check whether there is attached materials 
on the radar sensor and radar sensor cover, 
and if there is, remove it.
