The FEB system consists of a distance warning
function with an autonomous emergency brak-
ing function and adaptive brake assist function.
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 braking
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 detects that
there is a risk of a collision, you will be warned
visually and audibly.
The distance warning function issues a warning
at speeds:
•Of approximately 20 MPH (30 km/h) or more,
if, over several seconds the distance main-
tained 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, particularly
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 visually
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 braking
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 vehicles
•4–30 MPH (7 -50 km/h) for stationary ve-
hicles
Adaptive brake assist function
Adaptive brake assist function provides braking
assistance in hazardous situations at speeds
above 4MPH (7 km/h). It uses radar sensor
technology to assess the traffic situation.
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 increase the braking
force to a level suitable for the traffic condi-
tions.
If the adaptive brake assist function activates,
keep the brake pedal depressed until the emer-
gency 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 func-
tion is capable of reacting to moving objects
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 vehicle in
accordance with these system limitations
could result in serious injury or death.
•The FEB system cannot detect all vehicles
under all conditions.
•The radar sensor does not detect the follow-
ing 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 vehicle
ahead in the following conditions:
– Dirt, ice, snow or other material covering
the radar sensor.
– Interference by other radar sources.
– Snow or heavy rain.
– If the vehicle ahead is narrow (e.g. mo-
torcycle). –
If the vehicle ahead is in a different lane.
– Under strong radar reflections, for ex-
ample, in a multi-level parking garage.
– New vehicle or after a maintenance of the
FEB system. For additional information,
see Break-in schedule later in this sec-
tion
– 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 unnecessarily or give
an unnecessary warning. Always pay care-
ful attention to the traffic situation. Do not
rely solely on the distance warning function
and terminate the intervention if necessary.
•Braking distances increase on slippery sur-
faces.
•The system is designed to automatically
check the sensor’s functionality, within cer-
tain limitations. The system may not detect
some forms of obstruction of the sensor
area such as ice, snow, stickers, for ex-
ample. In these cases, the system may not
be able to warn the driver properly. Be sure
that you check, clean and clear the sensor
area regularly.
•Excessive noise will interfere with the warn-
ing chime sound, and the chime may not be
heard.
SYSTEM TEMPORARILY UNAVAILABLE
If the FEB stops working due to a malfunction or
some other reason, one of the following three
messages will be displayed in the vehicle infor-
mation display.
•[Emergency Brake Currently Unavailable See
Operator’s Manual]
•[Emergency Brake Inoperative]
•[Radar Sensors Dirty See Operator’s Manual]
For each of these messages, possible causes
and solutions are listed below.
[Emergency Brake Currently Unavailable See
Operator’s Manual]: The FEB system is tempo-
rarily inoperative. Possible causes:
•The radar sensor system is temporarily inop-
erative, for example, due to electromagnetic
radiation emitted by nearby TV or radio sta-
tions or other sources of electromagnetic
radiation.
•The system is outside the operating tempera-
ture range.

ACTIVE SOUND ENHANCEMENT
Starting and driving5-67
Page 399 of 556

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 ultrasound.
It detects vehicles and open spaces on both
sides of the vehicle. A parking symbol indicates
a suitable parking space. Active steering inter-
vention 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 parking sensor system (see
Parking
sensor system (if equipped) later in this sec-
tion).
IMPORTANT SAFETY NOTES
WARNING
•IPA is only an aid. It is not a substitute for
your attention to the immediate surround-
ings. The responsibility for safe maneuver-
ing and parking remains with you.
•Make sure that no persons, animals or ob-
jects are in the maneuvering range
•When the parking sensor system is deacti-
vated, IPA is also unavailable.
•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 park-
ing procedure
•This system is not designed to prevent con-
tact with small or moving objects.
•If your vehicle sustains damage to the bum-
per fascia, leaving it misaligned or bent, the
sensing zone may be altered causing inac-
curate measurement of obstacles or false
alarms.
•This system is not designed to prevent con-
tact with small or moving objects.
•If your vehicle sustains damage to the bum-
per fascia, leaving it misaligned or bent, the
sensing zone may be altered causing inac-
curate measurement of obstacles or false
alarms.
CAUTION
Do not drive over obstacles such as curbs, as
you may damage the wheels or tires.
IPA may also display spaces not suitable for
parking, for example:
•Parking or stopping prohibition.
INTELLIGENT PARKING ASSIST (IPA) (IF
EQUIPPED)
5-68Starting and driving
Page 400 of 556

•In front of driveways or entrances and exits.
•Unsuitable surfaces.
Parking tips:
•On narrow roads, drive as closely as possible
past the parking space.
•Parking spaces that are littered or overgrown
might be identified or measured incorrectly.
•Parking spaces that are partly occupied by
trailer towing bars might not be identified as
such or be measured incorrectly.
•Snowfall or heavy rain may lead to a parking
space being measured inaccurately.
•Pay attention to the parking sensor system
warning messages during the parking proce-
dure.
•You can intervene in the steering procedure
to correct it at any time. IPA will then be
canceled.
•When transporting a load which protrudes
from your vehicle, you should not use IPA.
•Never use IPA when snow chains are fitted.
•Make sure that the tire pressures are always
correct. This has a direct influence on the
parking characteristics of the vehicle. Use IPA for parking spaces that are:
•Parallel or at right angles to the direction of
travel.
•On straight roads, not bends.
•On the same level as the road, e. g. not on
the sidewalk.
For vehicles with the towbar folded out, the
minimum length for parking spaces is slightly
longer.
If you have attached a trailer to your vehicle,
you may not use IPA. Once the electrical con-
nection is established between your vehicle and
the trailer, IPA is no longer available. The
parking sensor system is deactivated for the
rear area
DETECTING PARKING SPACES
The IPA system can only be used to park in
spaces that have vehicles directly on either side
of the parking space.
Objects located above the height range of IPA
will not be detected when the parking space is
measured. These are not taken into account
when the parking procedure is calculated, e. g.
overhanging loads, tail sections or loading
ramps of goods vehicles.
WARNING
If there are objects above the detection range,
IPA may steer too early. This could cause a
collision. There is a risk of an accident.
If objects are located above the detection
range, stop and switch off the IPA.
For further information on the detection range
see Range of the sensors later in this section.
IPA does not assist you parking in spaces at
right angles to the direction of travel if:
•Two parking spaces are located directly next
to one another.
•The parking space is directly next to a low
obstacle such as a low curb.
•You forward park.
IPA does not assist you parking in spaces that
are parallel or at right angles to the direction of
travel if:
•The parking space is on a curb.
•The system reads the parking space as being
blocked, for example, by foliage or grass
paving blocks.
•The area is too small for the vehicle to
maneuver into.
