In vehicles with automatic transmission, the
gear change points are modified to position
them in lower or higher engine speed ranges.
Additionally, the Eco profile activates the in-
ertia function, enabling consumption to be
further reduced.
In manual gearbox vehicles, the Eco profile
causes the gear change recommendation in-

Traffic sign detection system* 1)
Intr oduction The traffic sign detection system records the
st
and
ard traffic signs in front of the vehicle
with a camera located on the base of the in-
terior mirror and provides information about
speed limits and overtaking prohibitions.
Within its limitations, the system also dis-
plays additional signals, such as time-specif-
ic prohibitions, signs for vehicles towing trail-
ers ›››
page 273 or limitations that only apply
in the event of rain. Even on journeys without
signs, the system may display any applicable
speed limits.
In Germany, on motorways and vehicle roads,
besides speed limits and overtaking provi-
sions the system also displays the end of
prohibition signs. The valid speed limit at the
time in other countries is always shown. WARNING
The technology in the traffic sign detection
sys t
em cannot change the limits imposed by
the laws of physics and only works within the
system's limits. Do not let the extra conven-
ience afforded by the traffic sign detection
system tempt you into taking any risks when
driving. The system is not a replacement for
driver awareness. ●
Adapt
your speed and driving style to suit
visibility, weather, road and traffic condi-
tions.
● Poor visibility, darkness, snow, rain and fog
may
lead to the system failing to display traf-
fic signs or not displaying them correctly.
● If the camera's field of vision is dirty, cov-
ered or dam
aged, system operation may be
impaired. WARNING
The driving recommendations and traffic indi-
c ation s
shown on the traffic sign detection
system may differ from the actual current
traffic situation.
● The system may not detect or correctly
show al
l the traffic signs.
● Traffic signs and traffic regulations have
priority ov
er the recommendations and dis-
plays provided by the system. Note
In order not to compromise the system's op-
eration, p l
ease take the following points into
account:
● Regularly clean the area of vision of the
camera and k
eep it in a clean state, without
snow or ice. ●
Do not c o
ver the field of vision of the cam-
era.
● Always replace damaged or worn blades
when required t
o avoid lines on the camera's
field of vision.
● Check that the windscreen is not damaged
in the area of
the camera's field of vision. Note
● The u se of out
dated maps on the naviga-
tion system may cause the system to show
traffic signs incorrectly.
● In the waypoints mode of the navigation
syst
em, the traffic sign detection system is
only partly available. 1)

are displayed ››› Fig. 214 B in conjunction
with their corresponding additional signs.
The sign that is currently valid for the
driver is shown in the left side of the
screen For example, a maximum speed
limit of 130 km/h (100 mph)
››› Fig. 214 A.
A sign valid only in certain circum-
stances, e.g. 100 km/h (60 mph) is
shown second, together with the addi-
tional rain sign.
If the windscreen wiper is
working while you are driving, the signal
with the additional rain sign will be
shown first, on the left, as it is the one
that is applicable at the time.
A sign valid only with restrictions, e.g.
No overtaking at certain times, will be
displayed third ››› Fig. 214 C.
Speed warning
If the system detects that the permitted
speed is exceeded, it may warn the driver
with a “gong” and visually with a message
on the dash panel display.

steps of 5 km/h (3 mph) within a range of be-
tween 0 km/h (mph) and 20 km/h (12 mph)
above the maximum speed permitted.
Trailer mode
In vehicles equipped with a towing bracket
device from the factory and a trailer that is
electrically connected to the vehicle, it is pos-
sible to activate or deactivate the display of
specific traffic signs for vehicles with trailer,
such as speed limits or overtaking prohibi-
tions. Activation or deactivation is performed
on the infotainment system using the button and the
S

page 33.
For trailer mode, the display of speed limits
applicable to the type of trailer or to the legal
provisions can be adjusted. The speed is ad-
justed in steps of 10 km/h (5 mph) within a
range of between 60 km/h (40 mph) and
130 km/h (80 mph). If it is adjusted to a
speed greater than that which is permitted in
the country in question for driving with a
trailer, the system automatically displays the
usual speed limits, e.g. in Germany 80 km/h
(50 mph).
If the speed warning for the trailer is deacti-
vated, the system displays the speed limits
as if there were no trailer hitched. Limited operation
The traffic s
ign detection system has certain
limitations. The following cases may lead the
system to operate with limitations or not at
all:
● In the case of poor visibility, e.g. in snow,
rain, fog or int
ense mist.
● In cases of dazzling, e.g. caused by head-
on traffic or b
y the sun.
● When driving at high speeds.
● If the camera is covered or dirty.
● If the traffic signs are out of the camera's
field of
vision.
● If the traffic signs are partially or totally
cov
ered, e.g. by trees, snow, dirt or other ve-
hicles.
● In the case of traffic signs that do not fulfil
the regu
lations.
● In the case of damaged or bent traffic
signs.
● In the c
ase of variable messages on over-
head or g
antry signs (LED-based variable traf-
fic signs or other lighting units).
● If the maps on the navigation system are
not up-to-d
ate.
● In the case of adhesives affixed to vehicles
that depict
traffic signs, e.g. speed limits on
lorries.

Park Assist*
Relat
ed video Fig. 216
Smart solutions Introduction
The Park Assist system is an additional func-
tion of P
arkPi
lot ››› page 257 and helps the
driver to:
● find a suitable parking space,
● select a parking mode,
● park driving in reverse in suitable perpen-
dicul
ar and parallel spaces,
● park driving forwards in suitable perpen-
dicul
ar spaces,
● exit a parking space driving forwards from
a par al
lel space.
In vehicles with a Park Assist system and fac-
tory radio the front, rear and side areas are
represented, and the position of obstacles is
shown relative to the vehicle.
The Park Assist system is subject to certain
limitations inherent to the system and its use
requires special attention by the driver ››› .
WARNING
The technology used in the park assist sys-
tem in v
olves a series of limitations inherent
in the actual system and in the use of ultra-
sonic sensors. The use of Park Assist should
never tempt you to take any risk that may
compromise safety. The system is not a re-
placement for driver awareness.
● Any accidental movement of the vehicle
coul
d result in serious injury. ●
Adapt
your speed and driving style at all
times to suit visibility, weather, road and traf-
fic conditions.
● Certain surfaces of objects and garments
do not refl
ect the ultrasound sensors' sig-
nals. The system cannot detect, at least cor-
rectly, these objects or people wearing such
clothes.
● Ultrasound sensor signals may be affected
by e
xternal sound sources. In certain circum-
stances this may prevent them from detect-
ing people or objects.
● The ultrasound sensors have blind spots in
which ob
stacles and people are not regis-
tered.
● Monitor the area around the vehicle at all
times, sinc
e the ultrasound sensors do not
detect small children, animals or certain ob-
jects in all situations. WARNING
Quick turns of the steering wheel when park-
ing or e x
iting a parking space with Park As-
sist can cause serious injury.
● Do not hold the steering wheel during ma-
noeuvre
s to park or exit a parking space until
the system requests it. Doing so disables the
system during the manoeuvre, resulting in
the parking being cancelled. » 249

● The p ark
in
g manoeuvre does not end with-
in approximately 6 minutes following activa-
tion of the automatic steering.
● There is a fault in the system (the system is
temporari
ly unavailable).
● ASR is switched off.
● ASR or ESC intervene with regulation.
● The driver door is opened.
To re
start the manoeuvre it is necessary that
none of these things occur and that the
button is pressed again.
Special Characteristics
The Park Assist system is subject to certain
limitations inherent to the system. For exam-
ple, it is therefore not possible to enter or exit
a parking space on sharp bends. While entering or exiting a parking space, a
brief sign
al sounds to prompt the driver to
change between forward and reverse gears
(depending on the case). In successive ma-
noeuvres, the assistant tells the driver to
change gears, at the latest, when the contin-
uous audible signal is given (object present
at a distance of ≤30 cm) by Park Pilot.
When the Park Assist system turns the steer-
ing wheel with the vehicle stationary, the in-
strument panel also displays the symbol .
Keep the brake pedal depressed while the
symbol remains on the dash panel display to
turn the wheels with the vehicle stopped.
This way, the system will require fewer ma-
noeuvres to complete the parking action. Trailer mode
The Park As
sist system cannot be switched
on if the factory-fitted towing bracket
››› page 273 is electrically connected to a
trailer.
After changing a wheel
If, after changing a wheel, the vehicle stops
entering and exiting parking spaces correctly,
the circumference of the new wheel may be
different and the system may need to adapt
to it. The adaptation is automatic and takes
place during driving. Making turns slowly and
in both directions (20 km/h [12 mph]) for a
few minutes may contribute to this adapta-
tion process ››› in Introduction on

in time ››› .
Autom atic
braking intervention to avoid ex-
ceeding the speed limit
To avoid exceeding the speed limit of approx-
imately 7 km/h (4 mph) when entering or
leaving a parking space, the brakes may acti-
vate automatically. After automatically acti-
vating the brakes, the manoeuvres to enter or
exit a parking space may continue.
The brakes are only automatically activated
once for each attempt to enter or exit a park-
ing space. If the speed of approximately
7 km/h (4 mph) is exceeded again, the corre-
sponding operation is halted.
Automatic braking to reduce damages
Depending on certain conditions, the Park
Assist system can automatically brake the ve-
hicle when faced with an obstacle, briefly ac-
tioning and holding down the brake ped-
al ››› . Following this the driver must press
the br ak
e ped

is not a replacement for driver awareness.
● The Park Assist system is subject to certain
limitations
inherent to the system. In certain
situations, the automatic braking interven-
tion may only work in a limited way or not
work at all.
● Always be ready to use the brakes yourself!

the driver by visually and audibly warning
them about obstacles detected in front of
and behind the vehicle.
There are ultrasound sensors integrated in
the front and rear bumpers. When they detect
an obstacle, you are alerted by audible warn-
ings and visually on the Easy Connect sys-
tem.
In the event of danger of a frontal collision,
the audible warnings come from the front of
the vehicle, and in the event of the danger of
a rear-end collision they come from the rear.
Make particularly sure that the sensors are
not covered by adhesives, residues and the
like, as this could affect the system's opera-
tion. Cleaning instructions ››› page 287.
The approximate measurement range of the
sensors is:
1.20 m
1.60 m

As you approach the obstacle, the time inter-
val between the audible warnings will be re-
duced. When you reach around 0.30 m the
warning will be constant: do not continue to
move forward (or backward)!
If you maintain separation from the obstacle,
