Washer/wiper system Switching the wipers on/off and brief
wipe
General information
Do not use the wipers if the windshield is dry,
as this may damage the wiper blades or cause them to become worn more quickly.
Information ATTENTION
If the wipers are frozen to the windshield,
the wiper blades can be torn off and the wiper
motor can overheat when switching on. There
is a risk of damage to property. Defrost the
windshield prior to switching the wipers on.◀

Switching on
The lever automatically returns to its initial po‐
sition when released.
▷Normal wiper speed: tap up once.
The wipers switch to intermittent operation
when the vehicle is stationary.▷Fast wiper speed: tap up twice or tap once
beyond the resistance point.
Wipers change to normal speed when ve‐
hicle comes to standstill.
Switching off and brief wipe
The lever automatically returns to its initial po‐
sition when released.
▷Brief wipe: press down once.▷To switch off from normal wiper speed:
press down once.▷To switch off from fast wiper speed: press
down twice.
Interval mode or rain sensor
The concept Without the rain sensor, the frequency of the
wiper operation is preset.
The rain sensor automatically controls the time
between wipes depending on the intensity of the rainfall. The sensor is located on the wind‐
shield, directly behind the interior mirror.
Activating/deactivating
Press button on the wiper lever.
Wiping is started. If the vehicle is equipped
with a rain sensor: LED in wiper lever lights up.
When wipers are frozen to windshield, wiper
operation is deactivated.
During trip interruption with the rain sensor
switched on: if the trip is resumed within ap‐
prox. 15 minutes, the rain sensor is automati‐
cally activated again.
ATTENTION
If the rain sensor is activated, the wipers
can accidentally start moving in vehicle
washes. There is a risk of damage to property.
Deactivate the rain sensor in vehicle washes.◀

Gear shift indicatorThe conceptThe system recommends the most fuel effi‐
cient gear for the current driving situation.
General information
Depending on the vehicle's features and coun‐
try version of the vehicle, the gear shift indica‐
tor is active in the manual mode of the Step‐
tronic transmission.
Suggestions to shift gear up or down are dis‐
played in the instrument cluster.
On vehicles without a gear shift indicator, the
engaged gear is displayed.
DisplayingExampleDescriptionFuel efficient gear is set.Shift into fuel efficient gear.
Speed limit detection
The concept
Speed limit detection
Speed limit detection shows the current maxi‐
mum permitted speed in the instrument clus‐
ter. The camera in the area of the interior mir‐
ror detects traffic signs at the edge of the road
as well as variable overhead sign posts. Traffic
signs with extra symbols for wet road condi‐
tions, etc. are also detected and compared
with the vehicle's onboard data, such as for the
rain sensor, and will be displayed depending
on the situation. The system takes into ac‐
count the information stored in the navigation
system and also displays speed limits present
on routes without signs.
Information WARNING
The system does not release from the
personal responsibility to correctly assess visi‐
bility and traffic situation. There is risk of an ac‐
cident. Adjust the driving style to the traffic
conditions. Watch traffic closely and actively
intervene in the respective situations.◀
Overview
Camera
The camera is installed near the interior mirror.
Keep the windshield in the area behind the in‐
terior mirror clean and clear.

System limits
The system may not be fully functional and
may provide incorrect information in the fol‐
lowing situations:▷In heavy fog, rain or snowfall.▷When signs are fully or partially concealed
by objects, stickers or paint.▷When driving very close to the vehicle in
front of you.▷When driving toward bright lights or strong
reflections.▷When the windshield behind the interior
mirror is fogged over, dirty or covered by a
sticker, etc.▷In the event of incorrect detection by the
camera.▷If the speed limits stored in the navigation
system are incorrect.▷In areas not covered by the navigation sys‐
tem.▷When roads differ from the navigation,
such as due to changes in road routing.▷When passing buses or trucks with a
speed sticker.▷If the traffic signs are non-conforming.▷During calibration of the camera immedi‐
ately after vehicle delivery.▷When signs are detected valid for a parallel
road.

High-beam AssistantThe concept
The high-beam Assistant detects other traffic
participants early on and automatically
switches the high beams on or off depending
on the traffic situation. The assistant ensures
that the high beams are switched on, when‐
ever the traffic situation allows. In the low
speed range, the high beams are not switched
on by the system.
General information
The system responds to light from oncoming
traffic and traffic driving ahead of you, and to
adequate illumination, for example, in towns
and cities.
The driver can intervene at any time and switch
the high beams on and off as usual.
Activating1.Depending on the equipment, turn the light
switch into position
or .
2.Press button on the turn signal lever, ar‐
row.
The indicator lamp in the instrument
cluster is illuminated, when the low
beams are switched on.
The high beams are switched on and off auto‐
matically.
The blue indicator lamp in the instru‐
ment cluster lights up when the system
switches on the high beams.
Deactivating
The High-beam Assistant is deactivated when
manually switching the high beams on and off,
refer to page 73. To reactivate the High-beam
Assistant, press the button on the turn signal
lever.
System limits
The High-beam Assistant cannot serve as a
substitute for the driver's personal judgment of
when to use the high beams. Therefore, man‐
ually switch off the high beams in situations
where required to avoid a safety risk.
The system is not fully functional in the follow‐
ing situations, and driver intervention may be
necessary:▷In very unfavorable weather conditions,
such as fog or heavy precipitation.▷When detecting poorly-lit road users such
as pedestrians, cyclists, horseback riders
and wagons; when driving close to train or
ship traffic; and at animal crossings.▷In tight curves, on hilltops or in depres‐
sions, in cross traffic or half-obscured on‐
coming traffic on highways.▷In poorly-lit towns and cities and in the
presence of highly reflective signs.▷When the windshield behind the interior
mirror is fogged over, dirty or covered with
stickers, etc.

Press button. The green indicator
lamp lights up.
If the automatic headlamp control, refer to
page 101, is activated, the low beams will
come on automatically when you switch on the
front fog lights.

terior mirror clean and clear.
Switching on/off The Intelligent Safety systems are automati‐

Front-end collision warning
Depending on the equipment, the collision
warning system consists of one of the two sys‐
tems:
▷Front-end collision warning with City Brak‐
ing function, refer to page 118.▷Front-end collision warning with braking
function, refer to page 115
Collision warning with
braking function
The concept The system can help prevent accidents. If an
accident cannot be prevented, the system will
help reduce the collision speed.
The system sounds a warning before an immi‐
nent collision and actuates brakes independ‐
ently if needed.
The automatic braking intervention may be
executed with maximum braking force and for
a brief period only as necessary.
If the vehicle is equipped with Active Cruise
Control with Stop&Go, the front-end collision
warning is controlled via the cruise control ra‐
dar sensor in conjunction with a camera.
The front-end collision warning is available
even if cruise control has been deactivated.
With the vehicle approaching another vehicle
intentionally, the collision warning and braking
are delayed in order to avoid false system re‐
actions.
General information
The system issues a two-phase warning of a
possible danger of collision with vehicles at
speeds above approx. 3 mph/5 km/h. Time of
warnings may vary with the current driving sit‐
uation.
Detection range
It responds to objects if they are detected by
the system.
Information WARNING
Indicators and warnings do not relieve
the driver from personal responsibility. Due to
system limits, warnings or reactions of the sys‐
tem may not be output or they may be output

dent. Adjust the driving style to the traffic con‐
ditions. Watch traffic closely and actively inter‐
vene in the respective situations.◀
WARNING
Due to system limits, individual functions
can malfunction during tow-starting/towing
with the Intelligent Safety systems activated,
e.g., approach control warning with light brak‐
ing function. There is risk of an accident.
