■Screen description 
Vehicle center guide line
The line indicates the estimated vehicle center on the ground.
Vehicle width guide line
The line indicates a guide path when the vehicle is being backed straight up. 
The displayed width is wider th an the actual vehicle width. The line aligns with the estimated course  lines when the steering wheel is straight.
Estimated course lines
The lines show an estimated course when the steering wheel is turned.
Distance guide line
The line moves, together with the estimated course lines, in sync with the steering wheel. The line shows points approximately 0.5 m (1.5 ft.) (red) and approximately 
1 m (3 ft.) (yellow) from the ce nter of the edge of the bumper.
Distance guide line
The line shows distance behind the vehicle, a point approximately 0.5 m. (1.5 ft.) (blue) from the edge of the bumper.

■Area displayed on screen 
The parking assist monitor displays 
an image of the view from the
bumper of the rear area of the vehi-
cle. 
The image of the Lexus parking 
assist monitor can be adjusted. 
( P. 383)
• The area displayed on the screen may vary according to vehicle orien- 
tation conditions.
• Objects which are close to either corner of the bumper or under the 
bumper cannot be seen on the
screen. • The camera uses a special lens. The 
distance of the image that appears
on the screen differs from the actual distance. 
• Items which are located higher than
the camera may not be displayed on the monitor.

■Lexus parking assist monitor camera 
The camera for the parking assist 
monitor is located above the license
plate.
●Using the camera 
If dirt or foreign matter (such as wate r droplets, snow, mud etc.) is adhering 
to the camera, it cannot transmit a clear  image. In this case, flush it with a 
large quantity of water and wipe the  camera lens clean with a soft and wet 
cloth.
■Differences between the screen and the actual road 
The distance guide lines and the vehicl e width guide lines may not actually be 
parallel with the dividing lines of the  parking space, even when they appear to 
be so. Be sure to check visually. 
The distances between the vehicle width guide lines and the left and right 
dividing lines of the parking space may  not be equal, even when they appear 
to be so. Be sure to check visually. 
The distance guide lines give a distance  guide for flat road surfaces. In any of 
the following situations, there is a marg in of error between the guide lines on 
the screen and the actual distance/course on the road.

●When the ground behind the vehicle slopes up sharply 
The distance guide lines will 
appear to be closer to the vehicle
than the actual distance. Because
of this, objects will appear to be
farther away than they actually
are. In the same way, there will be
a margin of error between the
guidelines and the actual dis-
tance/course on the road.
●When the ground behind the vehicle slopes down sharply 
The distance guide lines will 
appear to be further from the
vehicle than the actual distance.
Because of this, objects will
appear to be closer than they
actually are. In the same way,
there will be a margin of error
between the guidelines and the
actual distance/course on the
road.

●When any part of the vehicle sags 
When any part of the vehicle sags 
due to the number of passengers
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 flat  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 following.
●Estimated course lines 
Visually check the surroundings 
and the area behind the vehicle.
In the case shown in the illustra-
tion, the truck appears to be out-
side 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 actu-
ally cross over the estimated
course lines. In reality if you back
up as guided by the estimated
course lines, the vehicle may hit
the truck.

●Distance guidelines 
Visually check the surroundings 
and the area behind the vehicle.
On the screen, it appears that a
truck is parking at point  . How-
ever, in reality if you back up to
point  , you will hit the truck.
On the screen, it appears that 
is closest and   is farthest away.
However, in reality, the distance to
 and   is the same and   is
farther than   and  .
