4-5. Using the driving support systems
■Conditions under which the RCTA func- tion will not detect a vehicle
The RCTA function is not designed to detect the following types of vehicles and/or objects:
●Vehicles approaching from directly behind
●Vehicles backing up in a parking space next to your vehicle
●Vehicles that the sensors cannot detect due to obstructions
●Guardrails, walls, signs, parked vehicles
and similar stationary objects*
●Small motorcycles, bicycles, pedestrians,
etc.*
●Vehicles moving away from your vehicle
●Vehicles approaching from the parking
spaces next to your vehicle*
*: Depending on the conditions, detection
of a vehicle and/or object may occur.
■Conditions under wh ich the RCTA func-
tion may not function correctly
●The RCTA function may not detect vehi-
cles correctly in the following situations: • When the sensor is misaligned due to a strong impact to the sensor or its sur-
rounding area • When mud, snow, ice, a sticker, etc. is covering the sensor or surrounding area
on the rear bumper • When driving on a road surface that is wet with standing water during bad
weather, such as heavy rain, snow, or fog • When multiple vehicles are approaching with only a small gap between each vehi-
cle • When a vehicle is approaching at high speed
• When a towing eyelet is installed to the rear of the vehicle.• When backing up on a slope with a sharp
change in grade
• When backing out of a shallow angle
parking spot
• Immediately after the RCTA function is
turned on • Immediately after the engine is started with the RCTA function on
• When the sensors cannot detect a vehi- cle due to obstructions
●Instances of the RCTA function unneces-sarily detecting a vehicle and/or object may increase in the following situations:
• When a vehicle passes by the side of your

vehicle • When the parking space faces a street and vehicles are being driven on the
street
• When the distance between your vehicle
and metal objects, such as a guardrail, wall, sign, or parked vehicle, which may reflect electrical waves toward the rear of
the vehicle, is short • When a towing eyelet is installed to the rear of the vehicle.

WARNING
■Cautions regarding the use of the function
The driver is solely responsible for safe driving. Always drive safely, taking care
to observe your surroundings.
The RCTA function is only a supplemen-
tary function which alerts the driver that a vehicle is approaching from the right or left at the rear of the vehicle. As the
RCTA function may not function cor- rectly under certain conditions, the driver’s own visual confirmation of safety
is necessary. Over reliance on this func- tion may lead to an accident resulting death or serious injury.
Active rear wing*
The vehicle is equipped with an
active rear wing that operates auto-
matically while the vehicle is being
driven. This active rear wing
enhances aerodynamic perfor-
mance, especially at high speeds,
contributing to a more stable ride.
The active rear wing can be con-
trolled manually using a switch.

display. (P.92)
The illustration used is intended as an
example, and may differ from the image
that is actually displayed on the multi-infor-
mation display.
■Routine tire inflation pressure checks
The tire pressure warning system does not
replace routine tire inflation pressure checks. Make sure to check tire inflation pressure as part of your routine of daily
vehicle checks.
■Situations in which the tire pressure warning system may not operate prop-
erly
●In the following cases, the tire pressure
warning system may not operate prop- erly.• If non-genuine Lexus wheels are used.
• A tire has been replaced with a tire that is not an OE (Original Equipment) tire.• A tire has been replaced with a tire that is
not of the specified size. • Tire chains etc. are equipped.• An auxiliary-supported run-flat tire is
equipped. • If a window tint that affects the radio wave signals is installed.
• If there is a lot of snow or ice on the vehi- cle, particularly around the wheels or wheel housings.
• If the tire inflation pressure is extremely higher than the specified level.• If wheels without tire pressure warning
valves and transmitters are used. • If the ID code on the tire pressure warn-ing valves and transmitters is not regis-
tered in the tire pressure warning
computer.
●Performance may be affected in the fol-
lowing situations. • Near a TV tower, electric power plant, gas station, radio station, large display,
airport or other facility that generates strong radio waves or electrical noise• When carrying a portable radio, cellular
phone, cordless phone or other wireless communication device
If tire position information is not correctly
displayed due to the radio wave conditions,
the display may be corrected by driving and
changing the radio wave conditions.
●When the vehicle is parked, the time taken for the warning to start or go off
could be extended.
●When tire inflation pressure declines rap-
idly for example when a tire has burst, the warning may not function.
■Warning performance of the tire pres-sure warning system
The warning of the tire pressure warning system will change in accordance with the
conditions under which it was initialized. For this reason, the system may give a warning
even if the tire pressure does not reach a low enough level, or if the pressure is higher than the pressure that was adjusted to when
the system was initialized.
