2023 MERCEDES-BENZ C CLASS COUPE Owners Manual

Exit warning
The exit warning is an additional function of Blind Spot Assist and Active Blind Spot Assist and can warn vehicle occupants attempting to leave a sta-
tionary 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 diMering speed.
The exit warning cannot warn drivers in these
situations.
Always pay particular attention to the traPc situation when opening the doors
and make sure there is suPcient clear-
ance.
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.\bVehicles with ambient lighting: the Warning
Support of the ambient lighting can be activa-
ted and deactivated (  page 132).\bThe warning assistance can diMer depending
on the equipment and may vary according to
the setting.
This exit warning is only available when Blind Spot
Assist is active.
Aser the vehicle is switched oM, the exit warning
continues to function for a few minutes. When the outside mirror warning lamp 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
Blind Spot Assist and Active Blind Spot Assist may be limited in the following 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 suPcient
distance to the side for other traPc or obstacles.
Warnings may be interrupted when driving along-
side long vehicles, for example trucks, for a pro- longed time.
Blind Spot Assist and Active Blind Spot Assist are
not operational when reverse gear is engaged.Driving and parking215

Additionally, the exit warning may be limited in thefollowing 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\bThe brake application function is only availa-
ble for vehicles with a Driving Assistance
Package.
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 approximately 20 mph (30 km/h) and approximately 125 mph
(200 km/h).
&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 signiNcantly.
= 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.216Driving and parking

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 179) 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).
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 you leave the lane without activating the turn signal indicator, but danger of a collision with amoving obstacle is detected in your lane, a steer-ing intervention does not occur.
Vehicles with Blind Spot Assist or Driving Assis-
tance Package: if the system detects an obstacle,
such as another vehicle in the adjacent lane, a steering intervention will occur regardless of the
turn signal indicator.
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

tance" menu
If the front wheel of the vehicle drives over a
detected lane marking, this will be highlighted red in the Assistance menu in the driver\bs display.
\bVehicles with active ambient lighting: if Warn-
ing Support is activated, the Active Lane
Keeping Assist warning is also accompanied
by ambient lighting (  page 132).
System limits
In the following situations, a lane-correcting steer-
ing intervention may not occur but rather a warn-
ing may be given on the steering wheel, depend- ing on the situation:
= You clearly and actively steer, brake or accel-
erate.
= If a driving safety system intervenes, such as
ESP n
, Active Brake Assist or Active Blind Spot
Assist.
= You have adopted a sporty driving style with
high cornering speeds or high rates of acceler-
ation.
= If transport equipment, for example a trailer or
bicycle rack, is attached to the trailer hitch
and the electrical connection has been cor-
rectly established.
218Driving and parking

The system may be impaired or may not function
particularly in the following situations:
= If there is poor visibility, e.g. due to insuPcient
illumination of the road, highly variable shade
conditions, rain, snow, fog or heavy spray.
= If there is glare, e.g. from oncoming traPc, the
sun or reOections.
= If there is dirt on the windshield in the vicinity
of the multifunction camera or if the camera is
fogged up, damaged or obscured.
= If there is dirt on the bumper in the area of the
radar sensors, or if they are damaged or cov-
ered.
= If there are no lane markings, or several
unclear lane markings are present for one
lane, e.g. around roadworks.
= If the lane markings are worn, dark or cov-
ered.
= If the distance to the vehicle in front is too
short and thus the lane markings cannot be
detected.
= If the lane markings change quickly, e.g. lanes
branch oM, cross one another or merge.=
If the road is very narrow and winding.
Observe the notes on driving systems and your responsibility; you may otherwise fail to recognizedangers (  page 179).

Pedestrian braking function
\bThis function is available only in vehicles with-
out the Parking Package. Vehicles with theParking Package are equipped with maneuver- ing assistant functions (  page 237).
The pedestrian braking function can prevent colli-
sions with pedestrians when the vehicle is back-
ing up at slow speeds. If the rear view camera
detects a person in the vehicle path, the vehicle
can be braked to a standstill.
The pedestrian braking function can intervene
under the following conditions:
= The vehicle is backing up at a speed below
9 mph (15 km/h).
= The camera image is shown in the central dis-
play.
The function is automatically active when the rear
view camera is switched on and cannot be deacti-
vated separately .
If automatic braking is triggered, the following
symbol appears in red in the camera image:

\bIf the function is not available, the same sym-
bol appears in gray.
The pedestrian braking function is only an aid. It is
not a substitute for your attention to the surround- ings. The responsibility for safe maneuvering andparking remains with you. Make sure that no per-
sons, animals or objects etc. are in the maneuver- ing range.
&WARNING Risk of accident caused by limi-
ted detection of the pedestrian braking function
The pedestrian braking function cannot always
clearly detect people. Other obstacles are not
detected by the function.
In these cases, the function may brake unnec-
essarily or not brake at all.
Always pay careful attention to the traPc
situation; do not rely on the pedestrian
braking function alone.Be ready to brake.Driving and parking221
