2-4. Using other driving systems
CAUTION
Handling the camera sensor (with driver monitor system)
■
Observe the following to ensure that the PCS functions correctly:
Keep the windshield clean at all times.
●
PCS effectiveness may be reduced due to the presence of raindrops, condensa-
tion, ice or snow on the windshield.
Do not change the installation position of a camera sensor, or remove and rein-
●
stall it. The direction of a camera sensor is precisely adjusted.
When it is cold, using the heater with air blowing to the feet may allow the upper
●
part of the windshield to fog up. This will have a negative effect on the images. In
such a case, use the windshield defogger to provide warm, dry air to the wind-
shield.
Do not place anything on the dashboard.
●
Images reflected on the windshield may reduce the effectiveness of a camera
sensor.
Do not attach a sticker or other items to the windshield near a camera sensor.
●
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:
There is an object between the driver monitor sensor and the driver' s face, such
●
as when the sensor is blocked.
A part of the driver' s face is covered.
●
The sensor or the driver' s face is exposed to intense light such as sunlight.
●
The driving posture is improper.
●
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.
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.
