WARNING
In certain situations, the system can-
not provide warnings or warnings may
be delayed if traffic conditions or other
external factors make it impossible for
the radar sensor or camera to detect a
pedestrian, a cyclist or a vehicle
ahead.
Warnings may not be provided if the
distance to the vehicle ahead is short,
or if movements of the steering wheel/
brake pedal are great, such as during
active driving.
The sensor system has a limited range
for pedestrians/cyclists and provides
warnings and braking effect most
effectively at speeds up to 30 mph
(50 km/h). For stationary or slow-mov-
ing vehicles, the system functions best
if your vehicle’s speed is below
approximately 45 mph (70 km/h).
Warnings for stationary or slow-mov-
ing vehicles may not be provided in
dark conditions or in poor visibility.
The Pedestrian and Cyclist Detection with Full
Auto Brake system uses the same radar sen-
sors as Adaptive Cruise Control. For more
information on the radar sensor and its limita-
tions, see Adaptive Cruise Control – limita-
tions (p. 193).
NOTE
If warnings are given too frequently, the
warning distance can be reduced (see Col-
lision warning* – operation (p. 212)). This
causes the system to provide later warn-
ings, which decreases the total number of
warnings provided.
WARNING
The system is not activated at speeds
under approx. 2 mph (4 km/h). There-
fore, it will not brake your vehicle if you
approach a vehicle ahead at very low
speed, such as when parking.
The driver's actions always have high-
est priority and override the Pedestrian
and Cyclist Detection with Full Auto
Brake system. This means that the
system will not intervene in situations
where the driver is actively steering,
braking or pressing the accelerator
pedal, even if a collision is imminent.
When Auto-brake has prevented a col-
lision with a stationary object, your
vehicle will remain at a standstill for
approx. 1.5 seconds. If your vehicle
has been braked for a moving vehicle
ahead, your vehicle's speed will be
reduced to the same speed as that
vehicle's.
