2022 MERCEDES-BENZ A-CLASS HATCHBACK Owners Manual

Warnings may be interrupted when driving along-
side long v
ehicles, for example lorries, for a pro-
longed time.
Blind Spot Assist is not operational when reverse
gear is engaged.
Blind Spot Assist and the exit warning are not
operational when a trailer is coupled to the vehi-
cle and the electrical connection has been cor-
rectly established.
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
Function of brake application (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 is
designed to help you avoid a collision. The course-correcting brake application is availa-
ble in t he speed range between approximately
30 km/h and 200 km/h. &
WARNING Risk of accident despit
e brake
application of Active Blind Spot Assist
A course-correcting brake application cannot
alw
ays prevent a collision. 
Always steer, brake or accelerate your-
self, especiall
y 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,
t
he red warning lamp Oashes in the outside mirror
and a warning tone sounds. In addition, display
1 indicating the danger of a side collision
appears in the Instrument 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
Note the system limitations of Active Blind Spot
Assist; you may otherwise not recognise the dan-
gers (  page 252).
Either a course-correcting brake application
appropriate to the driving situation, or none at all,
may occur 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.254
Driving and parking

=
A dr iving safety system intervenes, e.g. ESP n
or Active Brake Assist.
= ESP n
is deactivated.
= A loss of tyre pressure or a defective tyre is
detected.
= You are driving with a trailer and the electrical
connection to the trailer hitch has been cor-
rectly established.

Function of Active Lane Keeping Assist
A

ctive Lane Keeping Assist monitors the area in
front of your vehicle by means of the multifunction
camera (  page 223). It serves to protect you
against unintentionally leaving your lane. You will be warned by vibration pulses in the steering
wheel and guided b

y a course-correcting brake
application back into your lane.
Active Lane Keeping Assist is available in the
speed range between 60 km/h and 200 km/h.
Active Lane Keeping Assist can neither reduce the
risk of an accident if you fail to adapt your driving
style nor override the laws of physics. It cannot
take into account road, weather or traPc condi-
tions. Active Lane Keeping Assist is only an aid.
You are responsible for maintaining a safe dis-
tance to the vehicle in front, for vehicle speed, for
braking in good time and for staying in lane.
The status of Active Lane Keeping Assist is dis-
played in the on-board computer:

Conditions for a course-correcting brake applica-
tion (v ehicles without Driving Assistance Package)
Depending on the setting, a course-correcting
brake application occurs in the following situa-
tions (  page 257).
% The availability of this setting is dependent on
t
he country. If the function is activated in
countries in which this setting is not available,
a lane-correcting brake application is initiated
in the following situations:
Lane markings were detected on both sides of
the lane. The front wheel drives over a contin-
uous lane marking.
Standard se
tting
= A lane marking and the edge of a Nrm road
surface were detected. The front wheel drives
over a lane marking on the edge of the Nrm
road surface.
= A lane marking and an oncoming vehicle were
detected. The front wheel drives over the lane
marking. Sensitive se
tting
= All situations described under the Standard
setting.
= A continuous lane marking was detected and
driven over with the front wheel.
% A brake application may be interrupted at any
time if y

ou steer slightly in the opposite direc-
tion.

= A lane marking and an approaching vehicle, an
overtaking vehicle or vehicles driving parallel
to your vehicle were detected in the adjacent lane. The front wheel drives over the lane
mar

king.

System limits
N
o lane-correcting brake application occurs in the
following situations:
= 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.
= When ESP n
is deactivated. 256
Driving and parking

=
When dr iving with a trailer, the electrical con-
nection to the trailer has been correctly estab-
lished.
= If a loss of tyre pressure or a defective tyre is
detected and displayed.
If you deactivate the Active Lane Keeping Assist
warning and the lane markings cannot be clearly
detected, it is possible that no lane-correcting
brake application takes place (  page 257).
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 windscreen in the vicinity
of the multifunction camera or if the camera is
misted up, damaged or obscured.
= If there are no lane markings, or several
unclear lane markings are present for one
lane, e.g. around roadworks. =
If t he 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 carriageway is very narrow and winding.
= Vehicles with Driving Assistance Package: if
the radar sensors in the rear bumper are dirty
or covered in snow and an obstacle is detec-
ted in your lane, no lane-correcting brake
application takes place.

reversing camera is displayed in the media display
when reverse gear is selected. Dynamic guide
lines show the path the vehicle will take with the
current steering angle. This helps you to orient
yourself and to avoid obstacles when reversing.
The reversing camera is only an aid. It is not a
substitute for your attention to the surroundings.
The responsibility for safe manoeuvring and park-
ing remains with you. Make sure that there are no
persons, animals or objects etc., in the manoeu-
vring area while manoeuvring and parking.
% You can open the cover of the reversing cam-
er

only apply to road level.

The r

eversing camera will not function or will only
partially function in the following situations:
= The tailgate is open.
= There is heavy rain, snow or fog.
= The light conditions are poor, e.g. at night.
= Cameras, or vehicle components in which the
cameras are Ntted, are damaged, dirty or cov-
ered. Observe the information on vehicle sen-
sors and cameras (  page 223).
% Do not use the reversing camera in these
types of situations. Y

ou could otherwise injure
others or collide with objects when parking
the vehicle.
% The contrast of the display may be impaired
b

y direct sunlight or by other light sources,
e.g. when driving out of a garage. In this case,
pay particular attention.
% Have the display repaired or replaced if,
f
orexample, pixel errors considerably restrict
its use. 360° Camera
Function of the 360° Camera
The 360° Camer

a is a system that consists of
four cameras. The cameras cover the immediate
vehicle surroundings. The system assists you
when you are parking or at exits with reduced visi-
bility, forexample.
The views of the 360° Camera are always availa-
ble when driving forwards up to a speed of
approx. 16 km/h and when reversing.
The 360° Camera is only an aid and may show a
distorted view of obstacles, show them incorrectly
or not show them at all. It is not a substitute for
your attention to the surroundings. The responsi-
bility for safe manoeuvring and parking remains
with you. Make sure that there are no persons,
animals or objects etc., in the manoeuvring area
while manoeuvring and parking.
The system evaluates images from the following
cameras:
= Reversing camera
= Front camera
= Two side cameras in the outside mirrors 260
