ADVANCED PARKING GUIDANCE SYSTEM
209
The advanced parking guidance sys-
tem helps back up parking by display-
ing a rearview image in order to pro-
vide a reference for back up
maneuvering, as well as automatically
controlling the steering wheel when
backing into a target parking position
set on the screen. The system will not
automatically back up or regulate
speed.
The advanced parking guidance system is
not an automatic parking system. It is a
system to assist back up parking.
As the system only assists with parking in
a set target parking position, there are
times when the system will be unable to
render this assistance, depending on fac-
tors such as road surface or vehicle condi-
tion, or the distance to the set target park-
ing position.
Depending on the characteristics of the
camera lens, the distance to or position of
people or obstacles shown on the screen
may differ slightly from actual conditions.
SELECTING A LANGUAGE
See “  Selecting a language” on page 254
for the procedure to select a language.
Once you select a language, the advanced
parking guidance system will indicate that
language until you select another lan-
guage.CAUTION
Never depend on the advanced
parking guidance system entirely
when backing up. Always make
sure your intended path is clear.
Use caution, just as you would
when backing up any vehicle.
Never back up while looking only at
the screen. The image on the
screen is different from actual
conditions. Depicted distances
between objects and flat surfaces
will differ from actual distances. If
you back up while looking only at
the screen, you may hit a vehicle, a
person or an object. When backing
up, be sure to check behind and all
around the vehicle visually and
with mirrors before proceeding.
Back up slowly, using the brake
pedal to control the vehicle’s
speed.
If you seem likely to hit nearby ve-
hicles, obstacles or people, de-
press the brake pedal to stop the
vehicle, and then disable the sys-
tem by touching on the
screen.
Use the system for flat spaces.
As the steering wheel moves auto-
matically in the parallel parking as-
sist mode and parking assist
mode, be aware of the following
points:
Keep clothing such as neckties,
scarves and long sleeves away
from the steering wheel, as they
may become entangled. Also,
keep children away from the
steering wheel.
If you have long fingernails, be
careful not to injure yourself
when the steering wheel moves.

CAUTION
When backing up, be sure to check
your surroundings and behind the
vehicle for safety, and back up
slowly, depressing the brake pedal
to control vehicle speed.
If a collision seems likely, depress
the brake pedal to stop the vehicle,
then disable the system by touch-
ing on the screen.
7. Once the vehicle is mostly within
the target parking position, voice guid-
ance will give a message, and parallel
parking assist mode will finish.
For safety, voice guidance is given slightly
before the target parking position. Further-
more, at that point system control will fin-
ish, so grip the steering wheel firmly, and
finish parking in the desired position, using
the brake to control the vehicle’s speed.
Check in front and behind the vehicle visu-
ally and check with the mirrors while back-
ing up.

Tips for setting the target parking
position
Useful information for setting the target
parking position (green frame)
THE DISPLAY POSITION OF THE
GREEN FRAME
The system decides the initial positioning
of the green frame by the position of the
parking space detected by the front side
sensors or the position of the vehicle when
it stops, and by detecting the white lines of
the parking space in the camera image to
identify the parking space location.
The front side sensors identify the parking
space location and the white lines near
that location are detected.
The front side sensors cannot identify the
parking space location, or the parking
space location may be misaligned in the
following situations.
A vehicle is parked at the back of the
parking space or the sensors cannot
detect a parked vehicle due to vehicle
shape etc.
The sensors cannot detect a pole or
wall beside the parking space.
The sensors detect a pedestrian or ob-
ject near the parking space.
If there are no vehicles parked on either
side of the target parking space when your
vehicle stops, the approximate parking
space location is identified, and the white
lines in that location are detected. For this
reason, stopping in front of the parking
space will make the detection of target
parking space’s white lines easier.
Successful detection of the parking
space’s white lines may not be possible,
depending on the shape of the line.
