CAUTION
Do not install an accessory or the like within the sensor
detection range. Doing so may cause the Lexus park
assist system to malfunction, resulting in an accident.
NOTICE
The sensors do not detect an obstacle just under the
bumper. A short object, thin stake or the like will be
detected once but might not be detected as your
vehicle gets very close to such an object.
 If an obstacle is very close to your vehicle, it might
not be detected.
 If a sensor is subjected to a strong impact, it will not
operate properly.
The Lexus park assist system may not work properly in
the following cases:
When icicles, snowflakes or mud gets on the sensors.
If removed, the system will work properly.
 When the sensor is frozen.
If deiced, the system will work properly.
 When the sensor is covered with something.
If removed, the system will work properly. Especially in cold weather, a malfunction warning screen may
appear on
the display due to frozen sensors. If the “Clean Park
Sonar” appears on the display, be sure to clean the sensor. If
the “Clean Park Sonar” appears despite no mud, ice or
snowflakes on the sensor, the sensor might have
malfunctioned. Have your vehicle checked by your Lexus
dealer.
In the following conditions, the detection range may be
affected:
 When you stop your vehicle in extreme hot or cold weather.
 Foreign matter such as snowflakes or mud gets on the
sensor.

REAR VIEW MONITOR SYSTEM
The rear view monitor system assists the driver by
displaying an image of the rear of the vehicle while
backing up. The displayed image on the screen is a
horizontally reversed mirror image of the inside rear view
mirror.
To display the rear view image on the screen, place the
selector lever in the “R” position when the ignition switch
is in the “ON” position.
If you move the selector lever out of the “R” position, the screen
returns to the previous screen. Operating another function of
the navigation system will display another screen.
The rear view monitor system is a supplemental device
intended to assist back up. When backing up, be sure to check
behind and all around the vehicle visually.
CAUTION
 Never depend on the rear view monitor system
entirely when backing up. Always make sure your
intended path is clear.
Use caution just as you would when backing up any
vehicle.
 Never back up while looking only at the screen. The
image on the screen is different from actual
conditions. Depicted distances between objects and
flat surfaces will differ from actual distances. If you
back up while looking only at the screen, you may hit
a vehicle, a person or an object. When backing up, be
sure to check behind and all around the vehicle
visually and with mirrors before proceeding.
 Do not use the system when the trunk is not
completely closed.
 If the back of the vehicle is hit, the position and
mounting angle of the camera may change. Be sure
to have the camera’s position and mounting angle
checked at your Lexus dealer.
 If the temperature changes rapidly , such as when hot
water is poured on the vehicle in cold weather, the
system may not operate normally.

If the camera lens becomes dirty, it cannot transmit
a clear image. If water droplets, snow, or mud adhere
to the lens, rinse with water and wipe with a soft cloth.
If the lens is extremely dirty, wash it with a mild
cleanser and rinse.
 The displayed image may become darker and moving
images may be slightly distorted when the system is
cold. When backing up, be sure to check behind and
all around the vehicle visually and with mirror before
proceeding.AREA DISPLAYED ON SCREEN

The area covered by the camera is limited. Objects
which are close to either corner of the bumper or under
the bumper cannot be seen on the screen.
 The area displayed on the screen may vary according
to vehicle orientation or road conditions. REAR VIEW MONITOR SYSTEM CAMERA
31L352
The rear view monitor system camera is located on the trunk
as shown in the illustration. The camera uses a special lens.
The distance of the image that appears on the screen differs
from the actual distance.
In the following cases, it may become difficult to see the images
on the screen, even when the system is functioning.

In the dark (for example, at night)
 When the temperature near the lens is extremely high or low
 When water droplets are adhering to the camera, or when
humidity is high (for example, when it rains)
 When foreign matter (for example, snow or mud) adheres
to the camera lens
 When the sun or the beam of headlights is shining directly
into the camera lens

The dynamic radar/laser cruise control function has 2 cruise
control modes: vehicle−to−vehicle distance control mode for
maintaining an appropriate distance between vehicles, and a
conventional (fixed speed) cruise control mode for cruising at
preset speeds.

STARTING AND DRIVING
332To change to the vehicle
−to−vehicle distance control mode
from the conventional (fixed speed) cruise control mode, push
the lever in the “MODE” dire ction for longer than about 1
second.
CAUTION
In the conventional (fixed speed) cruise control mode,
a warning tone does not sound to warn you if you are too
close to the vehicle ahead, as neither the presence of
the vehicle ahead nor the vehicletovehicle distance is
detected. Pay special attention to the distance between
your vehicle and the vehicle ahead. Always confirm the
setting in the multiinformation display.
For the vehicle −to−vehicle distance control mode, see the
following description. For the conventional (fixed speed)
cruise control mode, see page 355.
Vehicletovehicle distance control mode
Dynamic radar cruise control—
The millimeter wave radar sensor in this system primarily
detects the reflected wave from the rear end of the vehicle
ahead of you to determine the presence of the vehicle
ahead as well as measuring the vehicletovehicle
distance. The detection range of the sensor is about 120
m (400 ft.) ahead.
When the dynamic radar cruise control is on, the driving
pattern (power, normal) of the automatic transmission is fixed
in the normal position, regardless of the position of the selector
switch.
CAUTION
The dynamic radar cruise control is not a
collisionavoidance system and will not prevent
accidents. The dynamic radar cruise control is a vehicle
speed control device that is intended for use only on
freeways or roads where the traffic is light or moderate.
To avoid serious injury, you must use caution and be
attentive to road and traffic conditions while using
dynamic radar cruise control.

STARTING AND DRIVING
334If no vehicle is running ahead of you:
1
Cruising at a fixed speed: If there is no vehicle detected
ahead, your cruising speed is maintained at the preset
speed from about 45 km/h (28 mph) to about 135 km/h (85
mph). The preset speed is displayed in the
multi−information display. For the vehicle speed setting,
see “Setting operation ” on page 340.
If a vehicle is detected ahead of you:
2 Deceleration cruising function: If a slower moving
vehicle is detected ahead of you, your vehicle cruising
speed decreases within the range of about 40 km/h (25
mph) to about 135 km/h (85 mph). The multi− information
display shows the preset speed, the detected vehicle
ahead and selected vehicle− to−vehicle distance. If your
vehicle gets closer to the vehicle ahead because of
insufficient automatic deceleration, then the warning tone
warns you to also manually apply brakes.
3 Followup cruising function: After deceleration, your
vehicle cruising speed changes in proportion to the speed
of the vehicle ahead to maintain an appropriate distance
from your vehicle to the vehicle ahead. The
vehicle −to−vehicle distance can be changed. For details,
see “Changing vehicle −to−vehicle distance setting” on
page 346.
4 Acceleration cruising function: If the vehicle ahead
changes lanes, your vehicle cruising speed will be
gradually increased up to the preset speed, and your
vehicle resumes fixed −speed cruising.
CAUTION
Under certain conditions where the vehicle in front
slows drastically, or is stopped, the dynamic radar/laser
cruise control will neither warn you nor decelerate. The
driver must depress the brake pedal to slow down,
ensuring collision avoidance or that sufficient
vehicletovehicle distance is maintained.
When vehicle −to−vehicle distance control mode is activated,
you must still be attentive to road and traf fic conditions. Should
your vehicle speed decrease below about 40 km/h (25 mph),
the dynamic radar/laser cruise control will shut off, requiring
you to apply the brakes to slow. When a vehicle ahead slows
suddenly, stops or a vehicle cuts in front, the system may slow
your vehicle abruptly, but the automatic braking will cease if the
speed decreases below about 40 km/h (25 mph) requiring the
driver’s manual application of brakes.
