2Vehicle width extension guide
lines
These lines indicate the estimated
vehicle width extension. When the
steering
wheel is straight (the vehicle
is straight), the vehicle width exten-
sion guide lines overlap with the esti-
mated course lines.
3Estimated course lines
These lines indicate the estimated
course in which the vehicle moves
backward. The lines move in sync
with the steering wheel.
4Distance guide line (yellow)
The line moves, together with the es-
timated course lines, in sync with the
steering wheel. The centre of the line
indicates a position on the ground
about 3 ft. (1 m) behind the rear
bumper of the vehicle.
If the steering wheel is not straight, a
discrepancy may occur.
5Distance guide line (red)
The line moves, together with the es-
timated course lines, in sync with the
steering wheel. The centre of the line
indicates a position on the ground
about 1.5 ft. (0.5 m) behind the rear
bumper of the vehicle.
If the steering wheel is not straight, a
discrepancy may occur.
6Distance guide line (green)
The line indicates a position on the
ground about 1.5 ft. (0.5 m) behind
the rear bumper of the vehicle.
7Guide line display mode button

These lines indicate the points at
which you should turn the steering
wheel fully and back up at the small-
est turning circle.
4Distance guide line
This line indicates a position on the
ground
about 1.5 ft. (0.5 m) behind on
the ground of the rear bumper of your
vehicle.

 1Approx. 1.5 ft. (0.5 m)
The distance that appears on the
screen between threedimensional ob-
jects (such as vehicles) and flat sur-
faces (such as the road) and the actual
distance differ as follows.
In reality,
A= B< C ( A and B are
equally far away;
C is farther than A
and B). However, on the screen, the sit-
uation appears to be
B< C< A.
On the screen, it appears that a truck is
parking about 1.5 ft. (0.5 m) away. Howev-
er, in reality if you back up to point
B, you
will hit the truck.
The width of the
truck
Estimated course line display mode—The
estimated course lines are displayed ac-
cording to flat surfaces (such as the road).
It is not possible to determine the position
of the three− dimensional objects (such as
vehicles) using the estimated course.
In the case shown above, the truck ap-
pears to be outside of the lines and the ve-
hicle do es not look as if it will hit the truck.
However, the width of the truck extends out
from the truck in a line, and this line may
actually be on the lines. In reality if you
back up as guided by the lines, the vehicle
may hit the truck.
Similarly, when the lines pass near any ob-
ject(s) or obstacle(s), be sure to check the
area behind and around the vehicle visual-
ly.

3. Turn the steering wheel so that the esti-
mated course lines are within the parking
space, and back up carefully.4. When the rear of the vehicle is within
the parking space, turn the steering wheel
in order to equalize the left and right inter-
vals between the vehicle width extension
lines and the parking space side lines.

5. When the vehicle width extension lines
and the parking space side lines are paral-
lel, straighten the steering wheel (straight
backward position) and then carefully
back up until the entire vehicle is within the
parking space.
Even if the distance guide line and the
parking space rear edge appear to be par-
allel on the screen, in reality they may not
be parallel.
Example of how to use the system
when parking (perpendicular park-
ing)
The following example describes the pro-
cedure for pulling into a parking space on
the left. For pulling into a parking space on
the right, substitute right for left and vice
versa in all steps.
1. Put the shift lever in the “R” position. If
any other display mode is selected, switch
to guide line display mode.
2. While referring to the screen and mir-
rors, back into the parking space.

3. Back up until the parking assist guide-
lines meet the left edge of the parking
space. Stop the vehicle, turn the steering
wheel all the way to the right, and back up
the vehicle to park.
The point at which turn the steering wheel
depends on the width of the parking space.4. When the vehicle is in the parking
space, turn the steering wheel so that the
vehicle width extension guide lines and the
clearance to the left and right of the parking
space are about the same near the vehi-
cle. Back up slowly.

5. Turn the steering wheel so that the ve-
hicle width extension guide lines are paral-
lel with the parking space lines. When the
lines are parallel, straighten the steering
wheel and back up slowly.
Even if the distance guide line and the
parking space rear edge appear to be par-
allel on the screen, in reality they may not
be parallel.When there is only one line dividing the
spaces in a parking lot, even if the vehicle
width extension guide lines and the park-
ing space right side (left side) appear to be
parallel on the screen, in reality they may
not be parallel.
