Warn and Brake Assist
General safety instructions
WARNING
System unavailable or
only available to a limited
extent
The system supports the driver within the system
limits but cannot prevent an accident under all
circumstances.
The driver is ultimately responsible for reacting ap-
propriately to prevent an accident.
e
Drive with extreme care.
e
Always pay attention to the traffic situation and
the vehicle surroundings.
e Always be prepared to take control of the vehicle
if the system becomes unavailable or does not
function as expected.
System limitations
Within the system limits, the system can warn
against impending frontal collisions and initiate ap-
propriate braking maneuvers (depending on the
country) or provide steering support (depending on
the equipment). Not all road users and dangerous
situations can be detected correctly and in time.
The side areas of the vehicle and the rear are not
monitored.
In complex driving situations, the system may issue
undesired warnings and perform undesired braking
interventions.
Depending on the danger detected, not all Warning
and Brake Assist protection measures might be
triggered.
The system is available as of walking speed and can
react to pedestrians or cyclists up to a speed of
approx. 53 mph (85 km/h). It can react to vehicles
up to a speed of 156 mph (250 km/h).
The system does not react to animals, cross traffic
or objects such as poles, fences or rail vehicles.
On vehicles with Turn Assist, the system also reacts
to oncoming vehicles.
This function is not available:
– When reversing
– If brake lights are defective
– If there is a fault in the PSM or if the PSM is
switched off
– If there is a fault in the airbag control unit
The function may be restricted or unavailable
in the following instances:
– Up to 10 seconds after establishing operational
readiness
– If the seatbelts are not fastened
– In sharp curves
– When encountering reflective objects such as
crash barriers or entering a tunnel
– In heavy rain, snowfall, fog and ice
– If the windshield is damaged
– If the bumper is damaged, such as from parking
collisions
– If the radar sensor is damaged or dirty
– If there is a fault in the Adaptive Cruise Control
(ACC)
Responding to warning symbols
Always heed any warning and information messages
displayed in the vehicle.
> Please see chapter "Warning and information
messages" on page 244.
Operating principle
The warning and brake assistant can initiate actions
in certain hazardous situations to protect passen-
gers and other traffic participants.
The warning and break assistant has the following
functions, depending on the country:
– Distance warning (depending on equipment)
– Collision warning
– Acute warning (warning jolt)
– Automatic braking and braking assistance
– Avoidance assistant (depending on the equip-
ment configuration)
– Turning assistant (depending on the equipment
configuration)
– Preventive occupant protection functions (de-
pending on equipment)
The camera behind the windshield and the radar
sensor in the automatic cruise control (ACC) (de-
pending on the equipment configuration) scan the
area in front of the vehicle. An impending frontal
collision with other road users (vehicles, pedestrians
or cyclists) can be detected.
Information
e Follow the respective country-specific regula-
tions, particularly with respect to driving, vehicle
spacing, speed, etc.
The driver is always responsible for complying
with the relevant regulations that apply in each
country.
e
Observe instructions for deactivating Warn and
Brake Assist.
e Observe information for setting the functions.
