LEXUS PARKING ASSIST
MONITOR
The parking assist monitor assists the
driver by displaying an image of the
view behind the vehicle while back-
ing up, for example while parking.
The parking assist monitor assists
with the following 2 backing-up op-
erations:
(1) Perpendicular parking (parking in
a garage, etc.)
(2) Parallel parking (parking at the
side of the road, etc.)
INFORMATION
The screen illustrations used in this
text are intended as examples, and
may differ from the image that is
actually displayed on the screen.
DRIVING PRECAUTIONS
When backing up, be sure to visually
check all around the vehicle both di-
rectly and using the mirrors before
proceeding. If you do not, you may
hit another vehicle, and could possi-
bly cause an accident.
Pay attention to the following pre-
cautions when using the parking as-
sist monitor.
CAUTION
The parking assist monitor is a sup-
plemental device intended to assist
the driver when backing up. Never
depend on the parking assist monitor
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 shown on the screen may
differ from the actual state, and you
could collide with another vehicle or
obstacles if backing up looking only
at the screen, possibly causing an
accident. When backing up, be sure to
visually check all around the vehicle
both directly and using the mirrors
before proceeding.
Be sure to back up slowly, depressing
the brake pedal to control vehicle
speed.
If you seem likely to hit nearby vehi-
cles, obstacles, people or mount the
shoulder, depress the brake pedal to
stop the vehicle, then disable the
assist system by selecting on
the screen to cancel the system.

CAUTION
The instructions given are only guide-
lines. When and how much to turn the
steering wheel will vary according to
traffic conditions, road surface condi-
tions, 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 vehicle before maneuvering into
it.
Do not use system in the following
cases:
• On icy or slick road surfaces, or in
snow
• When using tyre chains
• When the trunk is not closed com-
pletely
• When the retractable hardtop is open
partially. (IS250C)
• 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 visually check
all around the vehicle both directly
and using the mirrors before proceed-
ing.
If the tyre sizes are changed, the posi-
tion of the guide lines displayed on
the screen may change.
The camera uses a special lens. The
distances between objects and pedes-
trians that appear in the image dis-
played on the screen will differ from
the actual distances. (See page 345.)
