●When any part of the vehicle sags
When any part of the vehicle
sags due to the number of pas-
sengers or the distribution of
the load, there is a margin of
error between the guide lines
on the screen and the actual
distance/course on the road.
■When approaching three-dimensional objects
The estimated course lines target a fl at surfaced objects (such as the
road). It is not possible to determine the position of three-dimensional
objects (such as vehicles) using the estimated course lines and distance
guide lines. When approaching a three-dimensional object that
extends outward (such as the flatbed of a truck), be careful of the fol-
lowing.
●Estimated course lines
Visually check the surround-
ings and the area behind the
vehicle. In the case shown in
the illustration, the truck
appears to be outside of the
estimated course lines and the
vehicle does not look as if it will
hits the truck. However, the
rear body of the truck may
actually cross over the esti-
mated course lines. In reality if
you back up as guided by the
estimated course lines, the
vehicle may hit the truck.

However, in reality, the dis-
tance to and is the

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 vehicle 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 guid e 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 wheel will vary according to traffic con-
ditions, road surface conditions, vehicle condition, etc. when parking. It is neces-
sary 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 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.

CAUTION
●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 di stances between objects and pedestrians
that appear in the image displayed on th e screen will differ from the actual dis-
tances. ( P. 303)
●Estimated course line display mode: If the steering wheel is straight and the vehi-
cle width guide lines and the estimated cour se lines are not in alignment, have the
vehicle inspected by your Lexus dealer.
NOTICE
■How to use the camera
●The parking assist monitor may not operate properly in the following cases.
• If the back of the vehicle is hit, the position and mounting angle of the camera may change.
• As the camera has a water proof construction, do not detach, disassemble or modify it. This may cause incorrect operation.
• Do not strongly rub the camera lens. If the camera lens is scratched, it cannot transmit a clear image.
• Do not allow organic solvent, car wax, window cleaner or glass coat to adhere to the camera. If this happens, wipe it off as soon as possible.
• If the temperature changes rapidly, such as when hot water is poured on the
vehicle in cold weather, the system may not operate normally.
• When washing the vehicle, do not apply intensive bursts of water to the cam- era or camera area. Doing so may result in the camera malfunctioning.
• When the camera is used under fluorescent lights, sodium light or mercury light etc., the lights and the illuminated areas may appear to flicker.
●Do not expose the camera to strong impact as this could cause a malfunction.
If this happens, have the vehicle inspected by your Lexus dealer as soon as possi-
ble.
