■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.
●The instructions given are only guidelines.
When and how much to turn the steering wh eel will vary according to traffic condi-
tions, road surface conditions, vehicle condit ion, 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 or emergency tires
• When the trunk 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 scre en will differ from the actual distances.
