MERCEDES-BENZ S CLASS 2023 Owners Manual

The camera also detects and analyzes tra"Pc signs
with a restriction indicated by an additional sign
(e.g. when wet).
Tra"Pc Sign Assist portrays only selected signs in
the driver\bs display. Actual tra"Pc signs and speed
limits have priority over tra"Pc signs and speed
limits shown in the driver\bs display.
Also observe the following information:
= select a speed adapted to the tra"Pc, sur-
roundings and weather conditions
= observe actual tra"Pc signs
= observe applicable tra"Pc rules and regula-
tions
Observe the notes on driving systems and your responsibility; you may otherwise fail to recognize dangers (  page 252).Displays in the driver\bs display1Permissible speed2Permissible speed when there is a restriction3Additional sign with restriction
The system can show up to two tra"Pc signs in the
driver\bs display simultaneously. The system always prioritizes displaying speed limits. Up to one traf-
"Nc sign with a maximum permissible speed can be
shown in the head-up display. If two speed signs are shown in the driver display, e.g. in the case of
detected restrictions, the value of the le"s speed
limit 1 is always transmitted to Active Distance
Assist DISTRONIC for acceptance and shown in
the head-up display.
Examples of tra"Pc signs which can be displayed
Tra"Pc Sign Assist can detect and display following
tra"Pc signs 1:
= speed limits
= end of the speed limit
= overtaking restrictions
= play streets
= recommended speeds
Tra"Pc Sign Assist can detect following additional
signs 3 and, if necessary, analyze the relevance
of the restrictions using other vehicle sensors:
= when wet
Driving and parking279

=slippery road surfaces
= in fog
= temporary restrictions
= exits
= restrictions for car/trailer combinations
Tra"Pc Sign Assist also uses data from the digital
street map in the navigation system. When you
leave or enter a municipality or change roads, on
a freeway exit or slip road forexample, or a"ser you
turn at a intersection, the display on the driver\bs display can thus be updated without a tra"Pc sign
having been detected.\bRegularly update the digital road map of the
navigation system so that the tra"Pc sign
assistant can work optimally.
If Tra"Pc Sign Assist cannot determine the cur-
rently applicable maximum permissible speed
(e.g. due to missing signs), the following display
appears in the driver\bs display:
Tra"Pc Sign Assist is not available in all countries.
If the vehicle is in a country where Tra"Pc Sign
Assist is not supported, this is displayed continu-
ously.\bPlease also note the information on the dis-
play messages of the tra"Pc sign assistant
(  page 489).
Additional functions of Tra"Pc Sign Assist (coun-
try-speci"Nc)
Warning for no-entry signs: Tra"Pc Sign Assist can
warn you if you drive the wrong way down a sec-
tion of road, forexample on freeway slip roads or
one-way streets.

pedestrian crossings, provided that pedestrians
are in the danger zone or are moving towards it,
Tra"Pc Sign Assist can warn you up to a speed of
approximately 44 mph (70 km/h).
Warning at stop signs: Tra"Pc Sign Assist can warn
you up to a speed of approximately 44 mph
(70 km/h) if you are about to drive past a stop sign unintentionally. For this to be possible, thesigns must be clear, forexample if the systemdetects more than one stop sign, or a stop sign
can be con"Nrmed using the digital navigation
map. No warning can be issued if several di"Merent
signs are detected.
Warning at red lights: Tra"Pc Sign Assist can warn
you up to a speed of approximately 44 mph
(70 km/h) if you are about to drive through a red

qFunction of Active Blind Spot Assist with exit
warning
Active Blind Spot Assist uses radar sensors to
monitor the area up to 130 "s (40 m) behind and
10 "s (3 m) next to your vehicle.
The system can detect vehicles traveling from
speeds of approximately 8 mph (12 km/h) and
issue a warning if they move into the monitoring
range.
Status display in the driver\bs display

Driver display in the Assistance menu
If a vehicle is detected within the monitoring
range, the red warning lamp lights up in the corre-
sponding outside mirror. In the Assistance menu,
the lamp in outside mirror 1 also lights up red,
and the lane in which the vehicle is detected is hatched out.
If a vehicle is detected in the monitoring range
and you switch on the turn signal indicator in the
corresponding direction, a warning tone sounds
twice and the warning lamp "Oashes red in the
respective outside mirror. Red radar waves 2 are
displayed next to your vehicle in the assistance
graphic.
If the turn signal indicator remains on, the display in the outside mirror "Oashes for all other detected
vehicles, but no further warning tone sounds. If you overtake a vehicle quickly, no warning is
given.\bVehicles with active ambient lighting: if Warn-
ing Support is activated, the Active Blind Spot
Assist warning is also accompanied by ambi-
ent lighting (  page 174).
Observe the notes on driving systems and your
responsibility; you may otherwise fail to recognizedangers (  page 252).
&WARNING Risk of accident despite Active
Blind Spot Assist
Active Blind Spot Assist does not react to the
following:
= if you overtake a vehicle too closely so that
it is in the blind spot area
= if vehicles traveling at a much faster speed
approach and then overtake
Active Blind Spot Assist may not give warnings
or intervene in such situations.
Always pay careful attention to the tra"Pc
situation and maintain a safe distance at
the side of the vehicle.
Exit warning
The exit warning is an additional function of Active Blind Spot Assist and can warn vehicle occupantsattempting to leave the stationary vehicle about approaching vehicles.
&WARNING Risk of accident despite exit
warning
The exit warning neither reacts to stationary
objects nor to persons or road users approaching you at a greatly di"Mering speed.
The exit warning cannot warn drivers in these situations.
Always pay particular attention to thetra"Pc situation when opening the doors
and make sure there is su"Pcient clear-
ance.Driving and parking285

If a vehicle is detected in the monitoring range,
the red warning lamp lights up in the correspond- ing outside mirror.
If a vehicle occupant pulls the door handle on the side of the warning, a warning tone sounds twice
and the ambient lighting in the respective door
and the warning lamps in the corresponding out-
side mirror "Oash red.
Vehicles with MBUX Interior Assistant: the visual
warning begins as soon as the hand of a vehicle
occupant moves into the area of the door.\bVehicles with ambient lighting or active ambi- ent lighting: theWarning Support of the ambi-
ent lighting can be activated and deactivated
(  page 174).\bThe warning assistance can di"Mer depending
on the equipment and may vary according to
the setting.
The exit warning is only available when Blind Spot
Assist is active.
A"ser the vehicle is switched o"M, the exit warning
continues to function for a few minutes. When the outside mirror warning light "Oashes three times,
the exit warning is no longer available.
The exit warning is only an aid and not a substi-
tute for the attention of vehicle occupants. The responsibility for opening and closing the doorsand for leaving the vehicle remains with the vehi-cle occupants.
System limits
Active Blind Spot Assist may be limited in the fol-
lowing situations, in particular:
= if there is dirt on the sensors or the sensors
are obscured
= in poor visibility, e.g. due to fog, heavy rain or
snow
= if there are narrow vehicles, e.g. bicycles or
motorbikes
= if the road has very wide or narrow lanes
= if vehicles are not driving in the middle of their
lane
Warnings may be issued in error when driving
close to crash barriers or similar continuous lane borders. Always make sure that there is su"Pcient
distance to the side for other tra"Pc or obstacles.Warnings may be interrupted when driving along-
side long vehicles, for example trucks, for a pro- longed time.
Active Blind Spot Assist is not operational when
reverse gear is engaged.
Additionally, the exit warning may be limited in the
following situations:
= when the sensors are covered by adjacent
vehicles in narrow parking spaces
= when people approach the vehicle
= in the event of stationary or slowly moving
objects

q Function of the brake application of Active
Blind Spot Assist
If Active Blind Spot Assist detects a risk of a side
impact in the monitoring range, a course-correct- ing brake application is carried out. This isdesigned to help you avoid a collision.
The course-correcting brake application is availa- ble in the speed range between approximately20 mph (30 km/h) and approximately 125 mph
(200 km/h).286Driving and parking

&WARNING Risk of accident despite brake
application of Active Blind Spot Assist
A course-correcting brake application cannot
always prevent a collision.
Always steer, brake or accelerate your- self, especially if Active Blind Spot Assist
warns you or makes a course-correcting
brake application.Always maintain a safe distance at the
sides.
If a course-correcting brake application occurs, the red warning lamp "Oashes in the outside mirror
and a warning tone sounds. In addition, a display
1 indicating the danger of a side collision
appears in the driver\bs display.
In rare cases, the system may make an inappro- priate brake application. This brake application
may be interrupted at any time if you steer slightly
in the opposite direction or accelerate.
System limits
Either a course-correcting brake application
appropriate to the driving situation, or none at all, may occur especially in the following situations:
= Vehicles or obstacles, e.g. crash barriers, are
located on both sides of your vehicle.
= A vehicle approaches too closely on the side.
= You have adopted a sporty driving style with
high cornering speeds.
= You brake or accelerate signi"Ncantly.
= A driving safety system intervenes, e.g. ESP n
or Active Brake Assist.
= ESP n
is deactivated.
= A loss of tire pressure or a defective tire is
detected.

Active Lane Keeping Assist

qFunction of Active Lane Keeping Assist
Active Lane Keeping Assist monitors the area in front of your vehicle by means of the multifunctioncamera (  page 253) and can warn you before
you leave your lane unintentionally. The system can guide you back into your lane through a
course-correcting steering intervention and addi-
tionally warns you with vibration pulses in the steering wheel. Active Lane Keeping Assist is
available in the speed range between 37 mph (60 km/h) and 124 mph (200 km/h).
Driving and parking287

The system can intervene in the following situa-
tions:
= Active Lane Keeping Assist detects a lane
marking.
= One of your front wheels goes over a lane
marking.
If you activate the turn signal indicator, a steering
intervention does not occur on the corresponding
side.
If the system detects an obstacle, such as another vehicle in the adjacent lane, a steering interven- tion will occur regardless of the turn signal indica-
tor. If you leave the lane without activating the turn signal indicator, but danger of a collision with
a moving obstacle is detected in your lane, a steering intervention does not occur.
Display 1 will appear in the driver\bs display and a
warning tone will sound in the following situations:
= A steering intervention by Active Lane Keeping
Assist lasts longer than approximately ten sec-
onds.
= The system carries out two or more steering
interventions within approximately three
minutes without any steering intervention from the driver.
In the Active Lane Keeping Assist settings, you can set the sensitivity of the system and set thelevel of support. Additionally, you can set whether
the system should react to discontinuous lane
markings or only continuous lane markings
(  page 290).
