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.437) 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
bumper.
● If a radar sensor or the front bumper
needs to be removed and installed, or
replaced, contact your Lexus dealer.
● Do not paint the front bumper any
color other than an official Lexus color.
■ To avoid malfunction of the front cam-
era
Observe the following precautions.
Otherwise, the front camera may not
operate properly, possibly leading to an
accident resulting in death or serious
injury.
● Keep the windshield clean at all times.
• If the windshield is dirty or covered
with an oily film, water droplets, snow,
etc., clean the windshield.
• As some glass coating agents may
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.
