The collision warning system and City
Safety™ complement each other. For more
information on City Safety™, see page 169.
1 - Collision warning
The driver is first warned of a potentially immi-
nent collision.
The collision warning system detects pedes-
trians, stationary vehicles as well as vehicles
driving in the same direction in front of the car.
If there is a risk of collision with a pedestrian or
a vehicle, the driver's attention is attracted with
a flashing red warning signal (no. [1] in the illus-
tration on page 174) and an acoustic signal.

2 - Brake support
If the risk of collision has increased further after
the collision warning then the brake support is
activated.
This means that the brake system is prepared
for rapid braking by applying the brakes lightly,
which may feel like a slight jolt.
If the brake pedal is depressed sufficiently
quickly then full brake function is implemented.
Brake support also reinforces the driver's brak-
ing if the system considers that the braking is
not sufficient to avoid a collision.

Collision Warning with Auto Brake & Pedestrian Protection*

3 - Auto Brake
The automatic brake function is activated last.
If in this situation the driver has not yet started
to take evasive action and the risk of collision
is imminent then the automatic braking func-
tion is deployed - this takes place irrespective
of whether or not the driver brakes. Braking
then takes place with full brake force in order
to reduce collision speed, or with limited brake
force if it is sufficient to avoid a collision.

WARNING
The collision warning system does not
engage in all driving situations or traffic,
weather or road conditions. The collision
warning system does not react to vehicles
driving in another direction to the car or to
animals.
Warning only activated in the event of a high
risk for collision. This section "Function"
and the section "Limitations" inform about
limitations that the driver must be aware of
before using the Collision Warning system
with Auto Brake.
Warnings and brake interventions for
pedestrians are switched off at vehicle
speeds exceeding 80 km/h.
Warnings and brake interventions for
pedestrians do not work in darkness and
tunnels - not even when streetlights are lit.
The auto-brake function can prevent a col-
lision or reduce collision speed. To ensure
full brake performance, the driver should
always depress the brake pedal - even when
the car auto-brakes.
Never wait for a collision warning. The driver
is always responsible that the correct dis-
tance and speed are maintained - even
when the collision warning system with
auto-brake is used.
