Volvo XC90: Driver support / City Safety™
City Safety1 can alert the driver with light, sound and pulsations
in the brake pedal to help the driver detect pedestrians, cyclists, large animals
and vehicles.

Function overview
Audible signal at risk of collision
Collision warning symbol
Camera/radar sensor distance monitoring
The function can help the driver avoid a collision in e.g. stop-and-go traffic,
when changes in the traffic ahead and driver distraction could lead to an incident.
City Safety activates a brief, forceful braking in an attempt to stop your vehicle
immediately behind the vehicle or object ahead.
The function assists the driver by automatically applying the brakes if there
is an imminent risk of a collision and the driver does not react in time by braking
and/or steering away.
City Safety is activated in situations in which the driver should have applied
the brakes much earlier, which means that the system will not be able to assist
the driver in all situations. The function is designed to be activated as late as
possible to help avoid unnecessary intervention. Automatic braking will only be
applied after or during a collision warning.
Normally, the occupants of the vehicle will not be aware of City Safety except
when the system intervenes when a collision is imminent.
WARNING
- The function is supplementary driver support intended to facilitate
driving and help make it safer – it cannot handle all situations in all traffic,
weather and road conditions.
- The driver is advised to read all sections in the Owner's Manual about
this function to learn of its limitations, which the driver must be aware of
before using the function.
- Driver support functions are not a substitute for the driver's attention
and judgment. The driver is always responsible for ensuring the vehicle is driven
in a safe manner, at the appropriate speed, with an appropriate distance to
other vehicles, and in accordance with current traffic rules and regulations.

of the situations in which they might appear are provided below...
City Safety1 can help prevent a collision or lower the vehicle's speed
at the point of impact. The function consists of several subfunctions.
Ability to reduce speed
If the difference in speed between your vehicle and the obstacle is greater than
the speeds specified below, the City Safety auto-brake function cannot prevent a
collision, but it can help mitigate its effects...
Other information:
City Safety1 can assist the driver by automatically braking the
vehicle when it is not possible to avoid a collision by steering alone.
City Safety assists the driver by periodically attempting to predict possible
"escape routes" to the sides of the vehicle in the event a slow-moving or stationary
vehicle were to be detected at a late stage...
