Warning
with
braking
function
Display
A warning symbol appears in the instrument
cluster and in the Head-up Display if a collision with a detected vehicle is imminent.
SymbolMeasureSymbol lights up red: prewarning.
Brake and increase distance.Symbol flashes red and an acoustic signal sounds: acute warning.
You are requested to intervene by
braking or make an evasive maneuj
ver.
Prewarning
This warning is issued, e.g., when there is the impending danger of a collision or the distanceto the vehicle ahead is too small.
The driver must intervene actively when there
is a prewarning.
Acute
warning
with
braking
function
Acute warning is displayed in case of the immij nent danger of a collision when the vehicle apj
proaches another object at a high differential
speed.
The driver must intervene actively when there
is an acute warning. If necessary, the driver is
assisted by a minor automatic braking interj
vention in a possible risk of collision.
Acute warnings can also be triggered without
previous forewarning.
Braking
intervention
The warning prompts the driver himself/herself
to react. During a warning, the maximum brakj
ing force is used. Prerequisite for the brake
booster is sufficiently quick and hard stepping on the brake pedal. The system can assist with
some braking intervention if there is a risk of a collision. At low speeds vehicles may thus
come to a complete stop.
Manual transmission: during a braking interj
vention up to a complete stop, the engine may
be shut down.
The braking intervention is executed only if vej
hicle stability has not been restricted, for inj
stance by deactivating the DSC Dynamic Staj
bility Control.
The braking intervention can be interrupted by
stepping on the accelerator pedal or by acj
tively moving the steering wheel.
Object detection can be restricted. Observe
the limitations of the detection range and funcj tional restrictions.
System
limits
Safety
information WARNING
The system can react incorrectly or not
at all due to the system limits. There is a risk of
accidents or risk of property damage. Observe the information regarding the system limits
and actively intervene, if needed.'

E.g., the following situations may not be dej
tected:'ySlow moving vehicles when you approach them at high speed.'yVehicles that suddenly swerve in front of
you, or sharply decelerating vehicles.'yVehicles with an unusual rear appearance.'yTwo-wheeled vehicles ahead of you.
Functional
limitations
The system may not be fully functional in the
following situations:
'yIn heavy fog, rain, sprayed water or snowj
fall.'yIn tight curves.'yIf the driving stability control systems are limited or deactivated, for instance DSC
OFF.'yIf, depending on the vehicle equipment
version, the field of view of the camera in the mirror or the radar sensor is dirty or objscured.'yUp to 10 seconds after the start of the enjgine via the Start/Stop button.'yDuring calibration of the camera immedijately after vehicle delivery.'yIf there are constant blinding effects bej
cause of oncoming light, for instance from
the sun low in the sky.
Warning
sensitivity
The more sensitive the warning settings are,
such as the warning time, the more warnings
are displayed. However, there may also be an excess of false warnings.
Collision
warning
with
braking
function
Concept
The system can help prevent accidents. If an
accident cannot be prevented, the system will help reduce the collision speed.
The system sounds a warning before an immij
nent collision and actuates brakes independj
ently, if needed.
The automatic braking intervention is executed with limited braking force and for a brief period
only.
If the vehicle is equipped with Active Cruise
Control with Stop&Go, the approach control warning is controlled via the cruise control raj
dar sensor.
The approach control warning is available even
if cruise control has been deactivated.
With the vehicle approaching another vehicle
intentionally, the approach control warning and
braking are delayed in order to avoid false sysj
tem reactions.
General
information
The system issues a two-phase warning of a
possible danger of collision with vehicles at
speeds above approx. 3 mph/5 km/h. Time of
warnings may vary with the current driving sitj uation.
Detection
range
Objects that the system can detect are taken into account.

Indicators and warnings do not relieve
the driver from personal responsibility. Due to
system limits, warnings or reactions of the sysj

Acute warnings can also be triggered without

Braking
intervention
The detection of objects can be influenced by
technical system limitations, e.g. pedestrians or stationary objects. Limitations of the detecj
tion range and functional restrictions are to be
considered.
The warning prompts the driver himself/herself
to react. During a warning, the maximum brakj
ing force is used. Premise for the brake boosj
ter is sufficiently quick and hard stepping on
the brake pedal. The system can assist with automatic braking intervention if there is risk of
a collision. The intervention can bring the vehij
cle to a complete stop.
Manual transmission: During a braking interj
vention up to a complete stop, the engine may
be shut down.
The braking intervention is executed only if vej hicle stability has not been restricted, e.g. by deactivating the DSC Dynamic Stability Conjtrol.
Above approx. 130 mph/210 km/h the braking
intervention occurs as a brief braking pressure. No automatic delay occurs.
The braking intervention can be interrupted by
stepping on the accelerator pedal or by acj tively moving the steering wheel.

light
braking
function
The
concept The system can help prevent accidents with
pedestrians.
The system issues a warning in the city driving speed area if there is imminent danger of a colj
lision with pedestrians and includes a braking
function.
The camera in the area of the rearview mirror controls the system.
General
information
With sufficient brightness, the system warns
about possible collision danger with pedesj trians starting at approx. 6 mph/10 km/h to apj
prox. 35 mph/60 km/h and assists with braking
before a collision.
The system reacts to people who are within
the detection range of the system.
Detection
range
The detection area in front of the vehicle is divj ided into two areas:
'yCentral area, arrow 1, directly in front of thevehicle.'yExpanded area, arrow 2, to the right and
left of the central area.
A collision is imminent if pedestrians are loj
cated within the central area. A warning is isj
sued about pedestrians who are located within the extended area only if they are moving inthe direction of the central area.
Safety
information WARNING
Indicators and warnings do not relieve
the driver from personal responsibility. Due to
system limits, warnings or reactions of the sysj
tem may not be output or they may be output
too late or incorrectly. There is a risk of an acj

Detection
The
concept
Two radar sensors in the rear bumper monitor
the area behind and next to the vehicle at
speeds above approx. 30 mph/50 km/h.
The system indicates whether there are vehij
cles in the blind spot, arrow 1, or approaching from behind on the adjacent lane, arrow 2.
The lamp in the exterior mirror housing is dimj med.
Before you change lanes after setting the turn
signal, the system issues a warning in the sitj
uations described above.
The lamp in the exterior mirror housing flashes and the steering wheel vibrates.

Prewarning
The dimmed lamp in the exterior mirror housj ing indicates when there are vehicles in the

Acute
warning If the turn signal is set while a vehicle is in the
critical zone, the steering wheel vibrates briefly
and the lamp in the exterior mirror housing
flashes brightly.
The warning stops when the turn signal is
switched off, or the other vehicle leaves the
critical zone.
Brief
