 Close all the doors and windows, 

and turn the engine switch off.

 Confirm the type of fuel.

■

Fuel types

P.455

■

Fuel tank opening for unleaded gasoline

To help prevent incorrect fueling, your vehi-

cle has a fuel tank opening that only accom-

modates the special nozzle on unleaded 

fuel pumps.

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 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 electricity to 

build up, resulting in a possible 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.

site direction.

WARNING

■

When replacing the fuel tank cap

Do not use anything but a genuine Lexus 

fuel tank cap designed for your vehicle. 

Doing so may cause a fire or other inci-

dent which may result in death or serious 

injury.

WARNING

■

Lexus Safety System + A

The Lexus Safety System + A is designed 

to operate under the assumption that the 

driver will drive safely, and is designed to 

help reduce the impact to the occupants 

and the vehicle in the case of a collision 

or assist the driver in normal driving con-

ditions.
As there is a limit to the degree of recog-

nition accuracy and control performance 

that this system can provide, do not 

overly rely on this system. The driver is 

always responsible for paying attention 

to the vehicle’s surroundings and driving 

safely.

WARNING

●

Keep the radar sensors and their sur-

rounding areas on the front bumper 

clean at all times.

If a radar sensor or its surrounding area 
on the front bumper is dirty or covered 
with snow, the system may not operate 
and a warning message (

P.428) will be 

displayed.
If this occurs, clean off the dirt or snow 
and drive the vehicle for approximately 
10 minutes.
If the warning message does not disap-
pear, have your vehicle inspected by your 
Lexus dealer.

●

Do not attach accessories, stickers 

(including transparent stickers), alumi-

num tape or other items to the radar 

sensors or their surrounding area.

●

Do not subject a radar sensor or its 

surrounding area on the front bumper 

to a strong impact.

If a radar sensor is moved even slightly 
off position, the system may malfunction 
and vehicles may not be detected cor-
rectly.
In the following situations, have your 
vehicle inspected by your Lexus dealer.
• If a radar sensor or its surrounding 

area is subject to a strong impact

• If the area on the front bumper around 

a radar sensor is scratched or dented, 

or the front bumper has become par-

tially disengaged 

●

Do not disassemble the radar sensors.

●

Do not modify the radar sensors or 

their surrounding area on the front

affect the detection performance of 

the front camera, consult your Lexus 

dealer when using a glass coating 

agent.

• If a glass coating agent is applied to the 

windshield, it will still be necessary to 

use the windshield wipers to remove 

water droplets, etc. from the area of 

the windshield in front of the front 

camera.

●

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 system 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

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 sun-
light reflected from the surface of the sun-
shade may cause the temperature of the 
front camera 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.
