1. LEXUS PARKING ASSIST MONITOR*
The parking assist monitor assists the
driver by displaying an image of the view
behind the vehicle while backing up, for
example while parking.
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
The parking assist monitor is a supple-
mental device intended to assist the
driver when backin g up. When backing
up, be sure to visually check all around
the vehicle both directly and using the
mirrors before proceeding. If you do
not, you may hit another vehicle, and
could possibly cause an accident.
Pay attention to the following precau-
tions when using the parking assist mon-
itor.
*: If equipped
CAUTION
● Never depend on the parking assist mon-
itor entirely when backing up. The image
and the position of the guide lines dis-
played 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 vehi-
cle.
● The instructions gi ven are only guide-
lines. When and how much to turn the
steering wheel will vary according to traf-
fic conditions, 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
vehicle before maneuvering into it.

tem in the following cases:
• On icy or slick road surfaces, or in snow
• When using tire chains or emergency tires
• When the trunk is not closed com- pletely
• On roads that are not flat or straight, such as curves or slopes
● In low temperatures, the screen may

visually check all around the vehicle both
directly and using the mirrors before pro-
ceeding.
● 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 dis-
tances between objects and pedestrians
that appear in the image displayed on the
screen will differ from the actual dis-
tances. ( →P. 2 9 3 )
