DRIVER SUPPORT

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.
3 - Auto-brake
The automatic braking function is activated at the
last moment.
If the driver has not taken evasive action by this
stage and a collision is imminent, the automatic
braking function will be triggered. This occurs
whether or not the driver is pressing the brake
pedal. Full braking force will be applied to reduce
the speed at impact or reduced braking effect will
be applied if this is sufficient to avoid the colli-
sion.
The seat belt tensioners may be activated along
with the automatic braking function. See "Seat
belt tensioners" for more information.
In certain situations, auto-braking may begin with
a limited braking force before applying full brak-
ing force.
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 a slower-moving vehicle ahead, your
speed will be reduced to that vehicle's speed.
Auto-braking can always be cancelled if the
driver presses hard on the accelerator pedal.
NOTE
When City Safety activates the brakes, the
brake lights come on.
When City Safety applies the brakes, a text mes-
sage will appear in the instrument panel to notify
the driver that the function is/was activated.
WARNING
City Safety may not be used to change how
the driver operates the vehicle. The driver
must not only rely on City Safety to brake the
vehicle.

Setting a warning distance for City
Safety
City Safety is always active, but the function's
warning distance can be adjusted.
NOTE
The City Safety function cannot be deacti-
vated. It is activated automatically each time
the engine/electric motor is started.
The alert distance determines the sensitivity of
the system and regulates the distance at which
the light, sound and brake pulsations will be acti-
vated.
To select warning distance:
1. Select
Settings My Car IntelliSafe in
the center display's Top view.
2.
Under
City Safety Warning, tap Late,
Normal or Early to set the desired warning
distance.
If the driver feels that the
Early setting is giving
too many warnings or finds them irritating, the
Normal or Late warning distance settings can
be selected instead.
If the driver feels that the warnings are too fre-
quent and distracting, the warning distance can
be reduced. This will reduce the total number of
warnings, but it will also result in City Safety pro-
viding warnings at a later stage.
