●Vehicles with intuitive parking assist
If intuitive parking assist detects an
object while you attempt to park in a
parking space on the right, the black and yellow vertical pole could be
obscured by intuitive parking assist displa y. In this event, turn intuitive park-
ing assist switch off ( P. 235), and operate the vehicle while checking the
safety of the surrounding area direct visually and with mirror. After the
operation, turn the switch on.
●If the message “Steering wheel turned too far, please return.” is displayed
The steering wheel has been turned to o far, and the system cannot func-
tion. Return the steering wheel to its original position.
If the message is displayed before the outline is positioned over the desired
parking space, it is likely that the vehi cle is too far away from the shoulder.
Check that there is a gap of approximately 3 ft. (1 m) between your vehicle
and the parked vehicle.

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 chec k 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 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, 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 par king 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 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 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 perpendicular parking assist screen
Estimated course line display mode: If the steering wheel is straight and the vehicle
width extension guide lines and the estimated course lines 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 outline, do not use the pa rallel 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.

●Minimum projected turning circle & projected course line
Use the minimum projected turn-
ing circle & projected course line
(when displayed) to check the
vehicle’s path with relation to
obstacles. If the minimum pro-
jected turning circle line (blue) is
over the obstacle as shown in the
illustration, or the obstacle falls
within the minimum projected
turning circle, if you turn with the
minimum possible turning circle,
the vehicle may collide with the
object. When the projected
course line (yellow) is displayed,
be sure to operate the steering
wheel so that the obstacle stays
outside the projected course line
until the vehicle has passed the
object.
