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 displaye d on the screen may differ from the actual
state.
Use caution, just as you woul d 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 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
• When the back door is not closed completely
• On roads that are not flat or stra ight, 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 movi ng, or you may become unable to see the
image on the screen. Be sure to check dire ct 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 perpendicu
lar parking assist screen
Estimated course line display mode: If the steering wheel is straight and the vehicle
width guide lines and the estimated course lin es 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 ou tline, 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.
