2-4. Using other driving systems
n
Determining the direction the driver is facing (with driver monitor system)
The driver monitor function does not operate when the vehicle is stopped.
The direction the driver is facing may not be determined correctly if any of the fol-
lowing conditions exist:
l
There is an object between the driver monitor sensor and the driver’s face, such
as when the sensor is blocked.
l
A part of the driver’s face is covered.
l
The sensor or the driver’s face is exposed to intense light such as sunlight.
l
The driving posture is improper.
n
Headlights (with driver monitor system)
The near-infrared ray transmitter projects strong energy that is not visible. Although
the transmitter normally turns off when the vehicle is stopped, never look into the
headlights for your safety.
n
Limitations of the pre-collision system
Do not rely on the pre-collision system. Always drive safely, taking care to observe
your surroundings and checking for any obstacles or other road hazards.
n
Cautions regarding the assist contents of the system
By means of alarms and brake control, the pre-collision system is intended to assist
the driver in avoiding collisions through the process of LOOK-JUDGE-ACT. There
are limits to the degree of assistance the system can provide, so please keep in mind
the following important points.
l
Assisting the driver in watching the road
The pre-collision system is only able to detect obstacles directly in front of the
vehicle, and only within a limited range. It is not a mechanism that allows careless
or inattentive driving, and it is not a system that can assist the driver in low-visibil-
ity conditions. It is still necessary for the driver to pay close attention to the vehi-
cle's surroundings.
l
Assisting the driver in making correct judgment
When attempting to estimate the likelihood of a collision, the only data available
to the pre-collision system is that from obstacles it has detected directly in front of
the vehicle. Therefore, it is absolutely necessary for the driver to remain vigilant
and to determine whether or not there is a possibility of collision in any given situ-
ation.
CAUTION
