Actual vehicle speed is more than approximately 10 mph (16 km/h) below the
set vehicle speed.
At this time, the memorized set speed is not retained.●

CAUTION■
Conditions under which the vehicle-to-vehicle distance control may not function
correctly
Apply the brakes as necessary in the foll owing conditions as the radar sensor may
not be able to correctly detect vehicles ahead, and a fatal or serious accident may
result: ●
When water or snow thrown up by the surrounding vehicles hinders the function-
ing of the sensor●
When your vehicle is pointing upwards (caused by a heavy load in the luggage
compartment etc.)●
When the road curves or when the lanes are narrow●
When steering wheel operation or your position in the lane is unstable●
When the vehicle ahead of you decelerates suddenly■
Handling the radar sensor
Observe the following to ensure the cruise control system can function effectively.
Otherwise, the system may not function co rrectly and could result in an accident.●
Keep the sensor and grille cover clean at all times.
Clean the sensor and grille cover with a soft cloth so you do not mark or damage
them.●
Do not subject the sensor or surrounding area to a strong impact.
If the sensor moves even slightly off position, the system may malfunction. If the
sensor or surrounding area is subject to a strong impact, always have the area
inspected and adjusted by your Lexus dealer.●
Do not disassemble the sensor.●
Do not attach accessories or stickers to the sensor, grille cover or surrounding
area.
●
Do not modify or paint the sensor and grille cover.
●
Do not replace them with non-genuine parts.

Sensor detection information ●
Certain vehicle conditions and the su rrounding environment may affect the
ability of a sensor to correctly detect an obstacle. Particular instances where this
may occur are listed below.
• There is dirt, snow or ice on a sensor.
• A sensor is frozen.
• A sensor is covered in any way.
• The vehicle is leaning considerably to one side.
• On an extremely bumpy road, on an incline, on gravel, or on grass
• The vicinity of the vehicle is noisy due to vehicle horns, motorcycle engines,
air brakes of large vehicles, or other loud noises producing ultrasonic waves.
• There is another vehicle equipped with parking assist sensor s in the vicinity.
• A sensor is coated with a sheet of spray or heavy rain.
• The vehicle is equipped with a fender pole or radio antenna.
• Towing eyelets are installed.
• A bumper or sensor receives a strong impact.
• The vehicle is approaching a tall or right-angled curb.
• In harsh sunlight or intense cold weather.
• A non-genuine Lexus suspension (low ered suspension, etc.) is installed.
In addition to the examples above, there are instances in which, because of their
shapes, signs and other objects may be judg ed by a sensor to be closer than they
are. ●
The shape of the obstacle may prevent a sensor from detecting it. Pay particular
attention to the following obstacles:
• Wires, fences, ropes, etc.
• Cotton, snow and other materi als that absorb sound waves
• Sharply-angled objects
•Low obstacles
• Tall obstacles with upper sections projec ting outwards in the direction of your
vehicle

Rear view monitor system camera
■
Smear effect The rear view monitor system camera is
located on the back door as shown in the
illustration.
In the following cases, it may become diffi-
cult to see the images on the screen, even
when the system is functioning correctly. ●
The vehicle is in a dark area, such as at
night. ●
The temperature near the lens is
extremely high or low. ●
Water droplets are on the camera lens
or humidity is high, such as when it
rains. ●
Foreign matter, such as snow or mud,
adheres to the camera lens. ●
The sun or headlights are shining
directly into the camera lens. ●
A bright object such as a white wall is
reflected in the mirror surface over the
monitor. ●
The camera has scratches or dirt on it.
If a bright light, such as sunlight reflected
off the vehicle body, is picked up by the
camera, a smear effect* characteristic to
the camera may occur.
*: Smear effect A phenomenon that
occurs when a bright light is picked up by
the camera; when transmitted by the
camera, the light source appears to have
a vertical streak above and below it.
