uuHonda Sensing ®u Collision Mitigation Braking SystemTM (CMBSTM)
Continued
Driving
• When there is a group of people in front of your vehicle walking together side by
side.
• Surrounding conditions or belongings of the pedestrian alter the pedestrian’s
shape, preventing the system from recogn izing that the person is a pedestrian.
• When the pedestrian is shorte r than about 3.3 feet (1 meter) or taller than about
6.6 feet (2 meters) in height.
• When a pedestrian blends in with the background.
• When a pedestrian is bent over or squatting, or when their hands are raised or
they are running.
• When several pedestrians are walking ahead in a group.
• When the camera cannot correctly identify that a pedestrian is present due to an
unusual shape (holding luggage, body position, size).
■Automatic shutoff
The CMBSTM may automatically shut itself o ff and the safety support indicator
(amber) comes and stays on when:
• The temperature inside the system is high.
• You drive off-road or on a mountain road, or curved and winding road for an
extended period.
• An abnormal tire condition is detected (wrong tire size, flat tire, etc.).
• The camera behind the rearview mirror, or the area around the camera, including
the windshield, gets dirty.
Once the conditions that caused the CMBS
TM to shut off improve or are addressed
(e.g., cleaning), the system comes back on.
Limitations applicable to pedestrian detection only
