Vehicles with intuitive parking assist
If intuitive parking assist detects an object while you attempt to park in a
parking space on the right, the black and yellow vertical pole could be
obscured by intuitive parking assist display. In this event, turn intuitive park-
ing assist switch off (

P. 250), and operate the vehicle while checking the

safety of the surrounding area direct visually and with mirror. After the
operation, turn the switch on.

●

If the message “Steering wheel turned too far, please return.” is displayed
The steering wheel has been turned too far, and the system cannot func-
tion. Return the steering wheel to its original position.
If the message is displayed before the outline is positioned over the desired
parking space, it is likely that the vehicle is too far away from the shoulder.
Check that there is a gap of approximately 3 ft. (1 m) between your vehicle
and the parked vehicle.

Area displayed on screen
The parking assist monitor displays
an image of the view from the
bumper of the rear area of the vehi-
cle.
The image on the rear view monitor
system screen can be adjusted, refer
to the “MULTIMEDIA OWNER’S
MANUAL” or “NAVIGATION
SYSTEM OWNER’S MANUAL”.

• The area displayed on the screen

may vary according to vehicle orien-

tation conditions.

• Objects which are close to either

corner of the bumper or under the

bumper cannot be seen on the

screen.

• The camera uses a special lens. The

distance of the image that appears

on the screen differs from the actual

distance.

• Items which are located higher than the camera may not be displayed on the mon-

itor.

• If your vehicle is equipped with a backlit license plate, it may interfere with the dis-

play.

Lexus parking assist monitor camera
The camera for the parking assist
monitor is located above the license
plate.

●

Using the camera
If dirt or foreign matter (such as water droplets, snow, mud etc.) is adhering
to the camera, it cannot transmit a clear image. In this case, flush it with a
large quantity of water and wipe the camera lens clean with a soft and wet
cloth.

■

Differences between the screen and the actual road
The distance guide lines and the vehicle width guide lines may not actually be
parallel with the dividing lines of the parking space, even when they appear to
be so. Be sure to check visually.
The distances between the vehicle width guide lines and the left and right
dividing lines of the parking space may not be equal, even when they appear
to be so. Be sure to check visually.
The distance guide lines give a distance guide for flat road surfaces. In any of
the following situations, there is a margin of error between the guide lines on
the screen and the actual distance/course on the road.

286

4-5. Using the driving support systems

●

When the ground behind the vehicle slopes up sharply

The distance guide lines will
appear to be closer to the vehicle
than the actual distance. Because
of this, objects will appear to be
farther away than they actually
are. In the same way, there will be
a margin of error between the
guidelines and the actual dis-
tance/course on the road.

●

When the ground behind the vehicle slopes down sharply
The distance guide lines will
appear to be further from the
vehicle than the actual distance.
Because of this, objects will
appear to be closer than they
actually are. In the same way,
there will be a margin of error
between the guidelines and the
actual distance/course on the
road.

●

When any part of the vehicle sags
When any part of the vehicle sags
due to the number of passengers
or the distribution of the load,
there is a margin of error between
the guide lines on the screen and
the actual distance/course on the
road.

■

When approaching three-dimensional objects
The estimated course lines target a flat surfaced objects (such as the road). It
is not possible to determine the position of three-dimensional objects (such as
vehicles) using the estimated course lines and distance guide lines. When
approaching a three-dimensional object that extends outward (such as the
flatbed of a truck), be careful of the following.

●

Estimated course lines
Visually check the surroundings
and the area behind the vehicle.
In the case shown in the illustra-
tion, the truck appears to be out-
side of the estimated course lines
and the vehicle does not look as if
it will hits the truck. However, the
rear body of the truck may actu-
ally cross over the estimated
course lines. In reality if you back
up as guided by the estimated
course lines, the vehicle may hit
the truck.

CAUTION

■

When using the Lexus parking assist monitor system
The parking assist monitor is a supplemental device intended to assist the driver when

backing up. When backing up, be sure to check visually behind and all around the vehi-

cle before proceeding.
Observe the following precautions to avoid an accident that could result in death or

serious injuries.

●

Never depend on the parking assist monitor entirely when backing up. The image

and the position of the guide lines displayed on the screen may differ from the actual

state.

Use caution, just as you would when backing up any vehicle.

●

Be sure to back up slowly, depressing the brake pedal to control vehicle speed.

●

If you seem likely to hit nearby vehicles, obstacles, people or mount the shoulder,

depress the brake pedal to stop the vehicle, then disable the assist system by select

on the screen to cancel the system.

●

The instructions given are only guidelines.

When and how much to turn the steering wheel will vary according to traffic condi-

tions, road surface conditions, vehicle condition, etc. when parking. It is necessary to

be fully aware of this before using the parking assist system.

●

When parking, be sure to check that the parking space will accommodate your vehi-

cle before maneuvering into it.

●

Do not use the parking assist monitor in the following cases:
• On icy or slick road surfaces, or in snow

• When using tire chains

• When the back door is not closed completely

• On roads that are not flat or straight, such as curves or slopes.

●

In low temperatures, the screen may darken or the image may become faint. The

image could distort when the vehicle is moving, or you may become unable to see the

image on the screen. Be sure to check direct visually and with the mirrors all around

the vehicle before proceeding.

●

If the tire sizes are changed, the position of the guide lines displayed on the screen

may change.

●

The camera uses a special lens. The distances between objects and pedestrians that

appear in the image displayed on the screen will differ from the actual distances.

CAUTION

■

When using the perpendicular parking assist screen
Estimated course line display mode: If the steering wheel is straight and the vehicle

width guide lines and the estimated course lines are not in alignment, have the vehicle

inspected by your Lexus dealer.

■

When using the parallel parking assist screen

●

Do not use the system if the display is incorrect due to an uneven (curvy/hilly) road or

a non-straight road.

●

Make sure to operate the steering wheel only when the vehicle is stopped.

●

Be sure to check that there are no obstacles inside the blue outline.

If there are any obstacles inside the blue outline, do not use the parallel parking assist.

●

When positioning the blue outline over the parking space, be sure to position it so

that the extended blue line may not cross the tire of the vehicle parked in front of the

empty space.

●

If the extended line of the blue outline may be

crossing the parked vehicle, your vehicle is

too close. Check that there is a gap of

approximately 3 ft. (1 m) between your vehi-

cle and the parked vehicle.

NOTICE

■

How to use the camera

●

The parking assist monitor may not operate properly in the following cases.
• If the back of the vehicle is hit, the position and mounting angle of the camera may

change.

• As the camera has a water proof construction, do not detach, disassemble or

modify it. This may cause incorrect operation.

• When cleaning the camera lens, flush the camera with a large quantity of water

and wipe it with a soft and wet cloth. Strongly rubbing the camera lens may cause

the camera lens to be scratched and unable to transmit a clear image.

• Do not allow organic solvent, car wax, window cleaner or glass coat to adhere to

the camera. If this happens, wipe it off as soon as possible.

• If the temperature changes rapidly, such as when hot water is poured on the vehi-

cle in cold weather, the system may not operate normally.

• When washing the vehicle, do not apply intensive bursts of water to the camera or

camera area. Doing so may result in the camera malfunctioning.

• When the camera is used under fluorescent lights, sodium light or mercury light

etc., the lights and the illuminated areas may appear to flicker.

●

Do not expose the camera to strong impact as this could cause a malfunction.

If this happens, have the vehicle inspected by your Lexus dealer as soon as possible.
