WARNING
Warnings will only be provided if there is an
imminent risk of a collision taking place. The
driver should be aware of the system's limita-
tions before operating the vehicle.
Warnings and automatic braking for pedes-
trians and cyclists are deactivated at speeds
above 50 mph (80 km/h).
City Safety's auto-brake function can help
prevent a collision or reduce the speed at
which a collision occurs. However, the driver
should always apply the brakes, even if auto-
brake is operating.
The driver is always responsible for maintain-
ing the correct speed and distance in relation
to the vehicle ahead. Never wait for a collision
warning or for City Safety to intervene.
City Safety does not activate the auto-brake
function during fast acceleration.
City Safety maintenance may only be carried
out by a trained and qualified Volvo service
technician.
Function overview
Audio-visual collision warning
Distance monitoring by a camera and radar
sensor
When triggered, City Safety carries out three
steps in the following order:
1.
Collision warning
2.
Brake assistance
3.
Auto-brake
1: Collision warning
The driver is first alerted to the risk of an immi-
nent collision.
City Safety can detect pedestrians, cyclists or
vehicles that are stationary, are moving in the
same direction as your vehicle or are described in
the article "City Safety in crossing traffic." The
driver is alerted by a flashing red warning signal,
an audible signal and pulsations in the brake
pedal.
2: Brake assistance
If the risk of a collision increases, brake support
will be activated.
This function increases pressure on the brake
pedal if the driver does not apply enough pres-
sure to the pedal.
3: Auto-brake
The brakes will be applied automatically.
If the driver has not taken action at this stage and
a collision is imminent, auto-braking will be trig-
gered. Full braking effect will be used to avoid
the collision if possible or to make the speed at
the point of impact as low as possible.
In certain situations, auto-braking may begin with
limited effect before full braking is used.
If City Safety has prevented a collision, the vehi-
cle will be kept at a standstill until the driver
takes action. If the vehicle has slowed to avoid
colliding with the vehicle ahead, your speed will
be reduced to that vehicle's speed.
When auto-break is triggered, the seat belt pre-
tensioners may also be activated, see the article
"Seat belts" for additional information.
Auto-braking can be cancelled if the driver
presses hard on the accelerator pedal.
