264 ADVANCED PARKING GUIDANCE SYSTEM
2007 LS460L/LS460 Navigation from Aug. ’06 Prod. (OM50750U)
The advanced parking guidance sys-
tem helps back up parking by display-
ing a rear-view image in order to pro-
vide a reference for back up
maneuvering, as well as automatically
controlling the steering wheel when
backing into a target parking position
set on the screen. The system will not
automatically back up or regulate
speed.
The advanced parking guidance system is
not an automatic parking system. It is a
system to assist back up parking.
As the system only assists with parking in
a set target parking position, there are
times when the system will be unable to
render this assistance, depending on fac-
tors such as road surface or vehicle condi-
tion, or the distance to the set target park-
ing position.
Depending on the characteristics of the
camera lens, the distance to or position of
people or obstacles shown on the screen
may differ slightly from actual conditions.
Vehicles with Lexus parking assist-sen-
sors — when the Lexus parking assist-
sensors are turned on and an obstacle is
detected in front of or behind your vehicle,
a warning appears on the right top of the
screen. For details, see
“Owner’s Manu-
al”
.
SELECTING A LANGUAGE
See “Selecting a language” on page 175
for the procedure to select a language.
Once you select a language, the advanced
parking guidance system will indicate that
language until you select another lan-
guage.
CAUTION
Never depend on the advanced
parking guidance 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.
Back up slowly, using the brake
pedal to control the vehicle’s
speed.
If you seem likely to hit nearby ve-
hicles, obstacles or people, de-
press the brake pedal to stop the
vehicle, and then disable the sys-
tem by touching on the
screen.
Use the system for flat spaces.
As the steering wheel moves auto-
matically in the parallel parking as-
sist mode and parking assist
mode, be aware of the following
points:
Keep clothing such as neckties,
scarves and long sleeves away
from the steering wheel, as they
may become entangled. Also,
keep children away from the
steering wheel.
If you have long fingernails, be
careful not to injure yourself
when the steering wheel moves.

If there is a problem, stop the ve-
hicle and disable the system by
touching on the screen.
Be sure to check that the vehicle
can actually park in the target
space before beginning operation.
Do not use the system in the follow-
ing conditions:
Out side of parking areas
In unprepared parking area such
as gravel or sand
In parking areas that are crooked
or have level variations
On slippery or icy roads, or in
snow
If the asphalt is melted due to
harsh sunlight
If there are obstacles in the tar-
get parking position (inside the
green frame), or obstacles be-
tween the vehicle and the park-
ing space
If there are a large number of ve-
hicles or pedestrians passing
In areas unsuitable for parking
(overly small parking space, cliff
etc.)
If the image is hard to see due to
dirt, direct sunlight, shadow or
snow on the camera lens
If you are using tire chains or
emergency tire(s)
Do not use tires other than those
installed by the manufacturer, as
the system may not function cor-
rectly. Furthermore, if you change
the tires, there may be errors in the
positions of the lines and frames
displayed on the screen. If you
wish to change your tires, see your
Lexus dealer .
In the following conditions, as-
sisted parking in the set parking
position may not be possible:
The tires are extremely worn, or
the tire inflation pressure is low
You are carrying an extremely
heavy load
There is a load in one side of the
vehicle only, causing the vehicle
to lean
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.
As the camera has a water proof
construction, do not detach, disas-
semble or modify it. This may
cause incorrect operation.
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 ad-
here 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.
If you scrape the camera cover, or
scrub it with a hard brush or an
abrasive agent, you may scratch
the cover, leading to poor picture
quality.
Do not allow organic solvent, car
wax, window cleaner or paint coat-
ing to adhere to the camera. If this
happens, wipe it off as soon as
possible.

If the camera is subjected to a colli-
sion, or the camera orientation
confirmation lines are not in line
with the bumper, it is likely that the
camera position or angle of instal-
lation has become crooked. See
your Lexus dealer as soon as pos-
sible.
Use your own eyes to confirm the
vehicle’s surroundings, as the dis-
played image may become faint or
dark, and moving images will be
distorted, or not entirely visible
when the outside temperature is
low. When backing up, be sure to
check behind and all around the ve-
hicle visually and with mirror be-
fore proceeding.
Area displayed on screen
Image is displayed approximately level
on screen.
Corners of bumper
The area covered by the camera is limi-
ted. Objects which are close to either
corner of the bumper or under the
bumper cannot be seen on the screen.

road conditions.
The advanced parking guidance
system
The advanced parking guidance system
camera is located on the trunk as shown in
the illustration.
The camera uses a special lens. The dis-
tance of the image that appears on the
screen differs from the actual distance.
In the following cases, it may become diffi-
cult 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 camera has scratches or dirt
on it
When the sun or the beam of head-
lights is shining directly into the camera
lens

If a bright light (for example, sunlight re-
flected off the vehicle body) is picked up by
the camera, the smear effect∗, peculiar to
the CCD camera, may occur.
∗: Smear effect—A phenomenon that oc-
curs when a bright light (for example, sun-
light reflected off the vehicle body) is
picked up by the camera; when trans-
mitted by the camera, the light source ap-
pears to have a vertical streak above and
below it.
If you install the antenna of a wireless de-
vice close to the camera, the screen image
may be affected by the electromagnetic
waves, and the system may not function
correctly. Install an antenna away from the
camera.
The method for adjusting the picture quali-
ty of the advanced parking guidance sys-
tem is the same as that for the navigation
screen.
Instructions given are only examples.
When and how much to turn the steer-
ing wheel will vary according to traffic
conditions, road surface conditions,
vehicle condition, etc. when parking.
It is necessary to be fully aware of this
before using the advanced parking
guidance system.
Also, when parking, be sure to check
that the parking space will accommo-
date your vehicle before maneuvering
into it.
CAUTION
Depending on the circumstances of
the vehicle (number of passengers,
amount of luggage, etc.), the set tar-
get parking position displayed on the
screen may change. Be sure to check
visually behind and all around the ve-
hicle before proceeding.

The area surrounding the arrows.
The area near the lower touch-screen
button on the screen.
Areas too far away to park in the range
of 34.4 ft. (10.5 m) or more behind the
current position, and/or 16.4 ft. (5.0 m)
or more either left or right from the cur-
rent position.

IF THERE IS A SLOPE IN THE ROAD
The assisted parking position will be closer
to the middle of the road (further from the
shoulder) than the set target parking posi-
tion.
In this case, if you align the warning flag
with the rear of the forward parked vehicle,
and the green extension guide line with the
lower edge of the parked vehicle’s rear
wheel when setting the target parking posi-
tion, the left side of your vehicle will be
roughly in line with the left side of the front
parked vehicle once assisted parking is
complete. If you are parallel parking on the
opposite side of the road, left and right will
be reversed.
