Driving and Operating
detected pedestrian too quickly, FPB
provides a red flashing alert on the
windshield and rapidly beeps or pulses the
driver seat. FPB can provide a boost to
braking or automatically brake the vehicle.
This system includes Intelligent Brake Assist
(IBA), and the Automatic Emergency Braking
(AEB) system may also respond to
pedestrians. See Automatic Emergency
Braking (AEB) 0 248.
The FPB system can detect and alert to
pedestrians in a forward gear at speeds
between 8 km/h (5 mph) and 80 km/h
(50 mph). During daytime driving, the
system detects pedestrians up to a distance
of approximately 40 m (131 ft). During
nighttime driving, system performance is
very limited.
Warning
FPB does not provide an alert or
automatically brake the vehicle, unless it
detects a pedestrian. FPB may not detect
pedestrians, including children:
When the pedestrian is not directly
ahead, fully visible, or standing
upright, or when part of a group.
Warning (Continued)
Due to poor visibility, including
nighttime conditions, fog, rain,
or snow.
If the FPB sensor is blocked by dirt,
snow, or ice.
If the headlamps or windshield are not
cleaned or in proper condition.
Be ready to take action and apply the
brakes. For more information, see
Defensive Driving 0 170. Keep the
windshield, headlamps, and FPB sensor
clean and in good repair.
FPB can be set to Off, Alert, or Alert and
Brake through vehicle personalization. See
Collision/Detection Systems under Vehicle
Personalization 0 118.
Detecting the Pedestrian Ahead
(Continued)
FPB alerts and automatic braking will not
occur unless the FPB system detects a
pedestrian. When a nearby pedestrian is
detected in front of the vehicle, the
pedestrian ahead indicator will display
amber.
Front Pedestrian Alert
When the vehicle approaches a pedestrian
ahead too rapidly, the red FPB alert display
will flash on the windshield. Eight rapid
high-pitched beeps will sound from the
front, or both sides of the Safety Alert Seat
will pulse five times. When this Pedestrian
Alert occurs, the brake system may prepare
for driver braking to occur more rapidly
which can cause a brief, mild deceleration.
Continue to apply the brake pedal as
needed. Cruise control may be disengaged
when the Front Pedestrian Alert occurs.
