arning message The City emergency braking function is part
of
Fr
ont

Assist and is active whenever the
system is switched on.
Depending on the equipment, the City emer-
gency braking function may be switched on
and off in the Easy Connect system using
the  button and the

 page 27. The City Emergency braking function picks
up, at s

peeds between approximately 4 km/h
(2.5 mph) and 30 km/h (19 mph), the traffic
situation in front of the vehicle.
If the system detects a possible collision with
a vehicle in front of it, the vehicle prepares
for a possible emergency braking ››› .
If the driv
er f

ails to react to a possible colli-
sion, the system may brake the vehicle auto-
matically, by progressively increasing braking
effect driving to reduce speed in the event of
a collision. The system can thus help to re-
duce the consequences of an accident.
Status display
Automatic deceleration by means of the City
Emergency braking function is displayed on
the instrument panel by means of the ad-
vance warning ››› Fig. 210 1)
. WARNING
The smart technology included in the City
Emerg ency

braking function cannot defy the
laws of physics. The driver is always respon-
sible for braking in time.
● Adapt your speed and safe distance to the
vehicl
e in front of you at all times to suit visi-
bility, weather, road and traffic conditions. ●
The City Emer

gency braking function alone
cannot prevent accidents or serious injury.
● In complex driving situations, the City
Emergency
braking function may issue unnec-
essary warnings and intervene inopportunely
in braking, such as in work areas or if there
are metal rails.
● If the operation of the City Emergency brak-
ing fu
nction is impaired, for example, by dirt
or because the radar sensor has lost its set-
tings, the system may issue unnecessary
warnings and intervene inopportunely in the
braking.
● During driving, the City Emergency braking
function doe
s not react to people or animals
or vehicles crossing your path or which ap-
proach you head-on in the same lane. Note
● When the City Emer

gency braking function
causes a braking, the brake pedal is “hard-
er”.
● Automatic interventions on the brakes by
the City Emer
gency braking function may be
interrupted by pressing the clutch, accelera-
tor or moving the wheel.
● The City Emergency braking function can
brake the
vehicle until it stops completely.
However, the brake system does not halt the
vehicle permanently. Use the foot brake! »1)

table on page 2 Traffic Jam Assist helps the driver keep the
car w
ithin its

lane and to move in convoy in
case of traffic congestion or slow traffic.
Traffic Jam Assist is an additional function of
Lane Assist ››› page 213 and combines Lane
Assist functions with Adaptive Cruise Control
(ACC) ››› page 196. Therefore, it is essential
that you read these two chapters carefully
and note the limitations of the systems and
the information about them.
Operation of Traffic Jam Assist
At speeds of below 60 km/h (40 mph), Traffic
Jam Assist can maintain a (temporary) dis-
tance preset by the driver with respect to the
vehicle ahead and help stay within the lane
››› .
T o do thi
s, the sy

stem automatically controls
the acceleration, brakes and steering, and
slows down the vehicle until it stops fully
when behind another vehicle that is stop-
ping. It then automatically moves off again
when the car in front does so.
Traffic Jam Assist is designed only for use on
motorways and wide roads. Therefore, never
use it in city traffic.

The Fatigue detection informs the driver
when their driving behaviour shows signs of
fatigue. WARNING
Do not let the comfort afforded by the Fatigue
detection sy s

tem tempt you into taking any
risks when driving. Take regular breaks, suffi-
cient in length when making long journeys.
● The driver always assumes the responsibil-
ity of driv
ing to their full capacity.
● Never drive if you are tired. ●
The sys t

em does not detect the tiredness of
the driver in all circumstances. Consult the in-
formation in the section ››› page 225, System
limitations.
● In some situations, the system may incor-
rectly int
erpret an intended driving manoeu-
vre as driver tiredness.
● No warning is given in the event of the ef-
fect c
alled microsleep!
● Please observe the indications on the in-
strument p
anel and act as is necessary. Note
● Fatigue det ection h

as been developed for
driving on motorways and well paved roads
only.
● If there is a fault in the system, have it
check
ed by a specialised workshop.224

The Easy Connect system screen will only dis-
p l

y objects detected at the front, and the ve-
hicle's trajectory will be hidden.
Braked manoeuvre function* 3 Valid only with Parking system plus
If an o

bstacle is detected while reversing, the
braked manoeuvre function activates the
emergency brake. Depending on the equip-
ment, the braked manoeuvre function can al-
so activate the emergency brake while mov-
ing forwards.
The emergency braking function helps to
minimise collisions. The vehicle's speed
must be no higher than 10 km/h.
The braked manoeuvre function is active or
inactive when the parking light is lit or off, re-
spectively. If the emergency brake has been
activated, the function will remain inactive
until the gear is changed.
The limitations of Parking Aid apply.

g and safety warnings WARNING
● The Re ar As

sist does not make it possible
to precisely calculate the distance from ob-
stacles (people, vehicles, etc.) and nor can it
overcome the system's own limits, hence us-
ing it may cause serious accidents and inju-
ries if used negligently or without due care.
The driver should be aware of his/her sur-
roundings at all times to ensure safe driving.
● The camera lens expands and distorts the
field of
vision and displays the objects on the
screen in a different, vague manner. The per-
ception of distances is also distorted by this
effect.
● Some objects may, due to the resolution of
the disp
lay screen - not be displayed in a sat-
isfactory manner or may not be displayed at all. Take special care with thin posts, fences,
rai
lin

gs or trees that might not be displayed
on screen and could damage the vehicle.
● The rear assist has blind spots where it is
not pos
sible to represent people or objects
(small children, animals and certain objects
cannot be detected in its field of vision). Mon-
itor the vehicle's surrounding area at all
times.
● Keep the camera lens clean, free of ice and
snow
, and do not cover it.
● The system is not a replacement for driver
awar
eness. Supervise the parking operation
at all times, as well as the vehicle's surround-
ing area. Adapt your speed and driving style
at all times to suit visibility, weather, road
and traffic conditions.
● Do not be distracted from the traffic by
looking at
the screen.
● The images on the rear assist screen are
only tw
o-dimensional. Due to a lack of spatial
depth, protruding parts or holes in the road,
for example, are more difficult to detect or
may not be seen at all.
● Vehicle load modifies the representation of
the orientation lines
displayed. The width
represented by the lines diminishes with ve-
hicle load. Pay special attention to the vehi-
cle's surroundings when the inside of the ve-
hicle of the luggage compartment is carrying
a heavy load.
● In the following situations, the objects or
other vehic
les shown in the navigation sys-
tem display appear to be further away or » 231

– When the vehicle approaches objects
that are not on the ground surface or are
jutting out from it. These objects may al-
so be outside the camera's angle of vi-
sion when reversing. Note
● It i s

important to take great care and pay
special attention if you are not yet familiar
with the system.
