Driving and operating 185
9 Warning
This system is not intended to
replace the driver responsibility for
driving the vehicle and looking
ahead. Its function is limited to
supplemental use only. The driver
must continue to apply the brake
pedal as the driving situation
dictates.
Brake preparation system
When approaching a vehicle ahead
so quickly that a collision is likely, the
brake preparation system slightly
pressurises the brakes. This reduces
the response time, when a manual or
automatic braking is requested.
The brake system is prepared so that
braking can occur more rapidly.
The system operates up to a speed of
50 mph.
Emergency automatic braking
After the brake preparation and just
before the imminent collision, this
function automatically applies limited
braking to reduce the impact speed of
the collision or prohibit a crash.
The system operates up to a speed of
37 mph.
Below a speed of 25 mph the system
can apply full braking.
Forward looking brake assist
In addition to the brake preparation
system and emergency automatic
braking, the forward looking brake
assist function makes the brake assist
more sensitive. Therefore,
depressing the brake pedal less
strongly results in immediate hard
braking. This function helps the driver
brake quicker and harder before the
imminent collision.
The system operates up to a speed of
53 mph.
9 Warning
Active emergency braking is not
designed to apply hard
autonomous braking or to
automatically avoid a collision. It is
designed to reduce the vehicle
speed before a collision. It may not
react for pedestrians or animals.
After a sudden lane change, the
system needs a certain time to
detect the next preceding vehicle.
The complete attention of the
driver is always required while
driving. The driver shall always be
ready to take action and apply the
brakes and steer to avoid
collisions. The system is designed
to work with all occupants wearing
their seat belts.
System limitations
The active emergency braking has
limited or no function during rain,
snow or heavy dirt, as the camera
sensor can be covered by a water
film, dust, ice or snow. In case of
sensor blockage, clean the sensor
cover.
