Driving
● When tire chains, compact spare tire or
an emergency tire puncture repair kit are
used.
● When towing with the vehicle.
■ Situations in which the system may
operate even if there is no possibility of a
collision
In some situations, such as the following, the
system may operate even though there is
no possibility of a collision.
● When driving on a narrow road.
● When driving toward a banner, flag, low-
hanging branch or boom barrier (such as
those used at railroad crossings, toll
gates and parking lots).
● When there is a rut or hole in the surface
of the road.
● When driving on a metal cover (grating),
such as those used for drainage ditches.
● When driving up or down a steep slope.
● If a sensor is hit by a large amount of
water, such as when driving on a flooded
road.
● There is dirt, snow, water drops or ice on
a sensor. (Cleaning the sensors will
resolve this problem.)
● A sensor is coated with a sheet of spray
or heavy rain.
● When driving in inclement weather such
as fog, snow or a sandstorm.
● When strong winds are blowing.
● When vehicle horns, vehicle detectors,
motorcycle engines, air brakes of large
vehicles, the clearance sonar of other
vehicles or other devices which produce
ultrasonic waves are near the vehicle.
● If the front of the vehicle is raised or low-
ered due to the carried load.
● If the orientation of a sensor has been
changed due to a collision or other
impact.
● The vehicle is approaching a tall or
curved curb.
● Driving close to columns (H-shaped steel
beams, etc.) in multi-story parking
garages, construction sites, etc.
● If the vehicle cannot be driven in a stable
manner, such as when the vehicle has
been in an accident or is malfunctioning.
● On an extremely bumpy road, on an
incline, on gravel, or on grass.
● When tire chains, compact spare tire or
an emergency tire puncture repair kit are
used.
● When towing with the vehicle.
