Large animals
If there is a risk of colliding with a large animal,
City Safety can help reduce your vehicle's speed
by up to 15 km/h (9 mph).
The braking function for large animals is primarily
intended to mitigate the force of a collision at
higher speeds. Braking is most effective at
speeds above 70 km/h (43 mph) and less effec-
tive at lower speeds.

City Safety carries out three steps in the follow-
ing order:
1. Collision warning
2. Brake assistance
3. Auto-brake
Descriptions of what happens in these three
steps are provided below.
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 and are ahead of
your vehicle. City Safety can also detect pedes-
trians, cyclists or large animals that are crossing
the road in front of your vehicle.
If there is a risk of a collision with a pedestrian,
large animal, cyclist or another vehicle, or with a
vehicle described in the section "City Safety in
crossing traffic", the driver will be alerted with
light, sound and pulsations in the brake pedal. At
lower speeds, during hard braking or if the accel-
erator pedal is pressed, the brake pedal pulsation
warning will not be given. The intensity of the
brake pedal pulsations varies according to the
vehicle's speed.
2 - Brake assistance
If the risk of a collision increases after the colli-
sion warning, brake support will be activated.
If the system determines that the pressure the
driver is exerting on the brake pedal is insufficient
to prevent the collision, brake support will
increase pressure.
