The FEB system can help you to minimize the
risk of a collision with the vehicle in front or
reduce the effects of such a collision
If the FEB system detects that there is a risk
of a collision, you will be warned visually and
audibly. If you do not react to the visual and
audible collision warning, autonomous brak-
ing can be initiated in critical situations. If you
apply the brake yourself in a critical situation,
the adaptive brake assist function assists
you.
Distance warning function
The distance warning function can help you
to minimize the risk of a collision with the
vehicle in front or reduce the effects of such a
collision. If the distance warning function de-
tects that there is a risk of a collision, you will
be warned visually and audibly.
The distance warning function issues a warn-
ing at speeds:
•Of approximately 20 MPH (30 km/h) or
more, if, over several seconds the distance
maintained to the vehicle traveling in front
is insufficient. The distance warning light
then lights up in the combination meter.
•Of approximately 4 MPH (7 km/h) or
more, if you rapidly approach a vehicle in
front. An intermittent warning tone will
then sound and the distance warning light
will light up in the combination meter.
If a warning is issued:
•Brake immediately in order to increase the
distance from the vehicle in front.
or
•Take evasive action provided it is safe to
do so.
WARNING
Due to the nature of the system, particu-
larly complicated but non-critical driving
conditions may also cause the system to
display a warning.
Up to a speed of approximately 45 MPH
(70 km/h), the distance warning function can
also react to stationary (stopped or parked)
vehicles.
If you approach a stationary vehicle and the
distance warning function detects a risk of a
collision, the system will alert you both visu-
ally and acoustically.

Autonomous braking function
If the driver does not react to the distance
warning signal in a critical situation, the FEB
system can assist with the autonomous brak-
ing function
The autonomous braking function can help
the driver to avoid an accident or reduces the
effects of an accident.
The autonomous braking function is available
in the following speed ranges:
•4–125 MPH (7-200 km/h) for moving ve-
hicles
•4–30 MPH (7 -50 km/h) for stationary
vehicles
Adaptive brake assist function
Adaptive brake assist function provides brak-
ing assistance in hazardous situations at
speeds above 4 MPH (7 km/h). It uses radar
sensor technology to assess the traffic situa-
tion.
If the system detects a risk of collision with
the vehicle in front, it calculates the braking
force necessary to avoid a collision. If you
apply the brakes forcefully, the adaptive
brake assist function will automatically in-
crease the braking force to a level suitable for
the traffic conditions.If the adaptive brake assist function acti-
vates, keep the brake pedal depressed until
the emergency braking situation is over. ABS
prevents the wheels from locking.
The brakes will work normally again if:
•You release the brake pedal.
•There is no longer any danger of a collision.
•No obstacle is detected in front of your
vehicle.
The brake assist function is then deactivated.
At high speeds, the adaptive brake assist
function is capable of reacting to moving ob-
jects that have already been detected as such
at least once over the period of observation.
Up to a speed of approximately 45 MPH
(70 km/h), the adaptive brake assist function
reacts to stationary vehicles.

FEB SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations for
the FEB system. Failure to operate the ve-
hicle in accordance with these system limi-
tations could result in serious injury or
death.
•The FEB system cannot detect all ve-
hicles under all conditions.
•The radar sensor does not detect the
following objects:
–Pedestrians or animals
–Oncoming vehicles
–Crossing vehicles
•The radar sensor has some performance
limitations. For stationary vehicles, the
FEB system will not function when the
vehicle is driven at speeds over:
–
Approximately 31 MPH (50 km/h) for
the Autonomous braking function.
•The radar sensor may not detect a ve-
hicle ahead in the following conditions:
–Dirt, ice, snow or other material cov-
ering the radar sensor.
–Interference by other radar sources.
–Snow or heavy rain.
–If the vehicle ahead is narrow (e.g.
motorcycle).–If the vehicle ahead is in a different
lane.
–Under strong radar reflections, for
example, in a multi-level parking ga-
rage.
–New vehicle or after a maintenance
of the FEB system. For additional in-
formation, see "Break-in schedule"
later in this section
–When driving on a steep downhill
slope or roads with sharp curves.
–When towing a trailer.
•In some road or traffic conditions, the
FEB system may intervene unnecessar-
ily or give an unnecessary warning. Al-
ways pay careful attention to the traffic
situation. Do not rely solely on the dis-
tance warning function and terminate
the intervention if necessary.
•Braking distances increase on slippery
surfaces.
•The system is designed to automatically
check the sensor’s functionality, within
certain limitations. The system may not
detect some forms of obstruction of the
sensor area such as ice, snow, stickers,
for example. In these cases, the system
may not be able to warn the driver prop-
erly. Be sure that you check, clean and
clear the sensor area regularly.
•Excessive noise will interfere with the
warning chime sound, and the chime
may not be heard.

ACTIVE SOUND ENHANCEMENT
The active sound enhancement generates
sounds according to engine speed through
the speakers
2and woofer1(if equipped)
to enhance the quality of the engine sound.IPA is an electronic parking aid with ultra-
sound. It detects vehicles and open spaces on
both sides of the vehicle. A parking symbol
indicates a suitable parking space. Active
steering intervention can assist you during
parking and when exiting a parking space.
The driver controls the accelerator, brake and
gear shift. You may also use the Camera Aid-
ing Sonar (parking sensor) function (see "
Camera Aiding Sonar (parking sensor) func-
tion (if equipped)" later in this section).
IMPORTANT SAFETY NOTES
WARNING
•IPA is only an aid. It is not a substitute
for your attention to the immediate sur-
roundings. The responsibility for safe
maneuvering and parking remains with
you.
•Make sure that no persons, animals or
objects are in the maneuvering range
•When the sonar (parking sensor) func-
tion is deactivated, IPA is also unavail-
able.
•While parking or pulling out of a parking
space, the vehicle swings out and can
drive onto areas of the oncoming lane.
This could cause you to collide with
other road users. There is a risk of an
accident.
•Pay attention to other road users. Stop
the vehicle if necessary or cancel the IPA
