The fuel filler door will open within about
10 seconds of the switch being pressed.
Before refueling is possible, a message will
be shown on the multi-information display
in the instrument cluster to indicate the
progress of the fuel filler door opener.
2Turn the fuel tank cap slowly and
remove it, then hang it on the back
of the fuel filler door.
QIf the fuel filler door cannot be opened
 P.388
After refueling, turn the fuel tank cap
until you hear a click. Once the cap is
released, it will turn slightly in the
opposite direction.
QWhen “Check Fuel Cap” is displayed on
the multi-information display
The fuel tank cap may be unfastened or
loose. Turn the power switch off, check the
cap and tighten it securely. If the message
remains, wait a few seconds and then turn
the power switch off once again.

QLexus Safety System + 2.5
The Lexus Safety System + 2.5 is
designed to operate under the assump-
tion 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 conditions.
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.

OIf water droplets cannot be properly
removed from the area of the wind-
shield in front of the front camera by
the windshield wipers, replace the
wiper insert or wiper blade.

1804-5. Using the driving support systems
QIf 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.
OIn 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.
OIn 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 disap-
pear 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
• Depending on the conditions in the vicinity of the vehicle, the radar may judge the sur- rounding environment can not be properly re cognized. In that case, “Pre-Collision Sys-
SituationActions
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.271)
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.

1824-5. Using the driving support systems
The system can detect the following
(The detectable objects differs
depending on the function.):
Vehicles
 Bicyclists
 Pedestrians
QPre-collision warning
When the system determines that the
possibility of a frontal collision is high, a
buzzer will sound and a warning mes- sage will be displayed on the multi-
information display to urge the driver
to take evasive action.
QPre-collision brake assist
When the system determines that the
possibility of a frontal collision is high,
the system applies greater braking
force in relation to how strongly the
brake pedal is depressed.
QPre-collision braking
If the system determines that the possi-
bility of a frontal collision is extremely
high, the brakes are automatically
applied to help avoid the collision or
reduce the impact of the collision.
QEmergency steering assist
If the system determines that the possi-
bility of a frontal collision is high and
that there is sufficient space for the
vehicle to be steered into within its
lane, and the driver has begun evasive
maneuver or steering, emergency
steering assist will assist the steering
movements to help enhance the vehi-
cle stability and for lane departure pre-
vention. During operation, the
indicator will illuminate in green.
PCS (Pre-Collision System)
The pre-collision system uses a
radar sensor and front camera to
detect objects ( P.182) in front of
the vehicle. When the system
determines that the possibility of a
frontal collision with an object is
high, a warning operates to urge
the driver to take evasive action
and the potential br ake pressure is
increased to help the driver avoid
the collision. If the system deter-
mines that the possibility of a frontal
collision with an object is extremely
high, the brakes are automatically
applied to help avoid the collision or
help reduce the impact of the colli-
sion.
The pre-collision system can be dis-
abled/enabled and the warning tim-
ing can be changed. ( P.185)
