2-4. Using other driving systems

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, con-
densation, ice or snow on the windshield.

Do not change the installation position of a camera sensor, or remove and
reinstall it. The direction of a camera sensor is precisely adjusted.

When the windshield fogs up, use the windshield defogger to dry the
windshield.
During cold weather, using the heater with air blowing to the feet may
allow the upper part of the windshield to fog up, having a negative effect
on the images.

Do not place anything on the dashboard.
Images reflected on the windshield may reduce the effectiveness of a cam-
era sensor.

Do not attach a sticker or other items to the windshield near a camera sen-
sor.

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 following 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-crash safety system
Do not rely on the pre-crash safety system. Always drive safely, taking care
to observe your surroundings and checking for any obstacles or other road
hazards.
