Thin objects such as wire or rope
 Sound wave absorbing objects such as cotton or snow
 Objects with a sharp edge
 Tall objects with the upper part projected
 Shorter objects
Intuitive parking assist failure warning
If an error is detected when the intuitive parking assist is
turned on, the vehicle symbol comes on or flashes with
beeping sounds.
At this time steering guidance is temporarily stopped.
However, the sensors functioning properly continue their
obstacle detection. For details, see “When the detection range
of the sensors is shorter” on page 381.
The intuitive parking assist failure warning display is not given
in either of the following operations:
 Changing to another screen
 Turning off the main switch for the intuitive parking assist

Multiinformation display 2Screen
If foreign matter gets on the sensors and the intuitive
parking assist cannot detect the object properly, the
above message appears. At this time, the vehicle symbol
and the indicator bars corresponding to the faulty
sensors flash for about 7 seconds and 2 beeps sound 5
times.
After about 7 seconds, the sensor indicator bars will
cease flashing, however will stay lit until the affected
sensor is cleaned. Furthermore, the vehicle symbol will
continue to flash until the affected sensor is cleaned.
The above illustration shows the sensor on the left front of the
vehicle malfunctioning.
If the failure warning does not go off even after the foreign
matter is removed, the intuitive parking assist may be
malfunctioning. Have it checked by your Lexus dealer. When the sensor is malfunctioning

G31064
If the steering sensor cable is broken and signals cannot
be received, the vehicle symbol comes on and the
steering guide symbol and arrows flash.
If only the steering sensor is malfunctioning, the warning
appears only on the multi
−information display.
If this warning appears, have the sensor checked by your
Lexus dealer as soon as possible. When
the neutral point of the steering sensor is unknown
G31065
If the memorized neutral point of the steering is erased by
replacing the battery, the vehicle symbol, steering guide
symbol and arrows come on.
If only the neutral point of the steering sensor is unknown, the
warning appears only on the multi −information display.
If this warning appears, calibrate the neutral point of the
steering using either of the following:
 Turn the steering wheel either way fully and then in the
opposite direction fully and slowly, with the vehicle stopped.
 Drive on roads (with as few curves as possible and without
backing up) for more than about 5 minutes.
If this warning goes out, the calibration of the steering neutral
point is completed. If the warning still remains on, have the
sensor checked by your Lexus dealer as soon as possible.

Rear view monitor display (Vehicles with rear
view monitor system)
G31066
On vehicles equipped with rear view monitor system, a
warning appears on the right top of the rear view monitor
in the following conditions.
 When the selector lever is put in “R” and the rear view
monitor is turned on.
 When the intuitive parking assist main switch is turned on
and any sensor detects an obstacle.
Although “Display Off” is selected in the intuitive parking assist
setting screen, the warning appears on the right top of the rear
view monitor.
Dual sensors
G31067
 1 About 50 cm (1.5 ft.) to about 100 cm (3.0 ft.)
2About 37.5 cm (1.1 ft.) to about 50 cm (1.5 ft.)
3About 25 cm (0.8 ft.) to about 37.5 cm (1.1 ft.)
4Less than about 25 cm (0.8 ft.)
When the intuitive parking assist determines that the
collision will be unavoidable:
The indicator will flash yellow depending on the distance to the
obstacle. When the distance between the vehicle and the
obstacle is less than about 25 cm (0.8 ft.), the yellow indicator
will turn red.
When the intuitive parking assist determines that the
collision will be avoided by changing the steering:
The indicator will flash yellow depending on the distance to the
vehicle. The steering guide symbol and arrow do not appear.

STARTING AND DRIVING
383
When the intuitive parking assist determines that the
collision will be avoided with the present steering angle:
The indicator will come on in green.
However, if the sensors detect and determine an obstacle at
an angle to the front of the vehicle, the indicator will not come
on.
Beeps (except for avoidable collisions at the present
steering angle):
As distance to the obstacle gets closer, the interval of the
intermittent
sound gets shorter, and then finally to a continuous
sound when the distance between the vehicle and the obstacle
is less than about 25 cm (0.8 ft.).
CAUTION
 When an obstacle is detected within about 25 cm (0.8
ft.) from the vehicle, the dual sensors will change the
determination to an unavoidable collision.
 With long obstacles such as walls, the decision of the
sensor may change as the obstacle gets closer; from
certain avoidance to avoidance if steering is
changed; from certain avoidance to unavoidable
collision; and there are also times when the decision
will be changed from avoidance if steering is
changed, to certain collision.
When you move your vehicle, be sure to confirm a safe
distance around your vehicle with your eyes and drive
slowly, or an accident or injury may result.

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 engine switch
is selected in “IGON” mode.
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.
Vehicles with intuitive parking assist—
When the intuitive parking assist is turned on and an obstacle
is detected in front or rear of your vehicle, a warning appears
on the right top of the rear view monitor. For details, see
“Intuitive parking assist” on page 365.

STARTING AND DRIVING
389
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.
 Use your own eyes to assure rearward clearance, as
the displayed image may become faint or darker, and
moving images will be distorted or not entirely visible
when out side temperature is cold. When backing up,
be sure to check behind and all around the vehicle
visually and with mirror before proceeding.
