This function will operate in situ-
ations such as the following if an
object is detected in the travel-
ing direction of the vehicle.

Parking Support Brake

function (static

objects)

If the sensors detect a static
object, such as a wall, in the
traveling direction of the
vehicle and the system
determines that a collision
may occur due to the vehi-
cle suddenly moving for-
ward due to an accidental
accelerator pedal operation,
the vehicle moving the
unintended direction due to
the wrong shift position
being selected, or while
parking or traveling at low
speeds, the system will
operate to lessen the impact
with the detected static
object and reduce the
resulting damage.

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

check visually.



The distance guide lines give
a distance guide for flat road

lines on the screen and the
actual distance/course on the
road.

■

When the ground behind
the vehicle slopes up
sharply

The distance guidelines are pro-
jected on a horizontal surface,
distances on an upward sloping
surface appear farther from 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 distance/course

on the road.

When the ground behind
the vehicle slopes down
sharply

The distance guidelines are pro-
jected on a horizontal surface,
distances on an downward slop-
ing surface appear closer to the
vehicle than the actual distance.
Because of this, objects will
appear to be closer than they
