2022 MERCEDES-BENZ EQS SALOON Owners Manual

Active Emergency Stop Assist issues the following
w arnings in order:
= Display message 1 appears in the driver's
display.
= In addition to display 1 a warning tone
sounds.
= The message Beginning emergency stop will
appear in the driver's display, a continuous
warning tone will sound, the vehicle will no
longer accelerate and, if necessary, slight belt
tensioning will be produced.
= The vehicle speed is reduced in increments
until it is at a standstill. Sharp brake impulses
are also produced. %
Vehicles with Driving Assistance Package: If
A
ctive Distance Assist DISTRONIC is active
and the driver unfastens the seat belt and
driver's door, an emergency stop can be initi-
ated immediately.
Vehicles with Driving Assistance Package:
Depending on t
he country, a lane change to the
adjacent right-hand lane is carried out, if possible.
It is only possible to change across one lane and
only into the right-hand lane, and not onto the
hard shoulder.
When automatic braking is initiated, Active Dis-
tance Assist DISTRONIC is deactivated. Depend-
ing on the country, the hazard warning light sys-
tem is switched on.
When the vehicle is stationary, the following
actions are carried out:
= The vehicle is secured with the electric park-
ing brake.
= The vehicle is unlocked.
= If possible, an emergency call is placed to the
Mercedes-Benz emergency call centre. Before automatic braking is initiated, you can can-
cel A
ctive Emergency Stop Assist by steering.
You can cancel the intervention by Active Emer-
gency Stop Assist aser automatic braking is initi-
ated by one of the following actions:
= Accelerating or braking: the emergency stop is
cancelled, but the warning message, warning
tone and power steering remain active
= Steering: power-assisted steering is cancelled,
the warning message and warning tone remain
active and the vehicle continues to be braked
% Active Emergency Stop Assist can initiate an
emer
gency stop a maximum of three times
within a driving cycle. Aser that, Active Steer-
ing Assist and Active Emergency Stop Assist
are disabled until the vehicle has been restar-
ted.

Function of Active Lane Change Assist
A

ctive Lane Change Assist supports the driver
when changing lanes and is activated by indicat-
ing brieOy.
For this, the following conditions must be fulNlled:
= You are on a motorway or high-speed major
road.
= The vehicle speed is between approximately
80 km/h and 180 km/h. =
The neighbour
ing lane is separated by a bro-
ken lane marking.
= No vehicle or obstacle is detected in the adja-
cent lane.
= Since the last time the vehicle was started,
the sensors have detected a vehicle at a suita-
ble distance behind your vehicle.
= Active Lane Change Assist is selected in the
multimedia system.
= Active Distance Assist DISTRONIC and Active
Steering Assist are activated on motorways.
The system is not available and must be reactiva-
ted in the following situations:
= Active Distance Assist DISTRONIC and Active
Steering Assist were already activated before
entering the motorway.
= The system brieOy does not detect the road
you are on as a motorway or a motorway-like
road, e.g. on a motorway junction.
As soon as Active Lane Change Assist detects a
suitable road, you can reactivate it with J,
M or N. Display in the driver's display in the

menu 1
Green arrow: lane change initiated
2 Red arrow: lane change cancelled
When Active Lane Change Assist is available, the
± displa
y appears along with green arrows in
the driver's display. If the system has been activa-
ted but is not currently available, the ± display Driving and parking
263

appears along with grey arrows in the driver's dis-
pla y.
If no vehicle or obstacle is detected in the adja-
cent lane and a lane change is permitted, the lane
change begins aser the driver has indicated
brieOy. The lane change is shown to the driver
with a Oashing green arrow next to the ±
steering wheel symbol. Green arrow Assistance is
displayed in the appropriate adjacent lane in the
1 menu in the driver's display. Themessage, for
Lane change to the left example, also appears.
Active Lane Change Assist can be cancelled in
various situations, including the following:
= Change in the surrounding conditions (e.g.
detected obstacle).
= The driver removes their hands from the steer-
ing wheel.
= The driver steers with too much force or in the
opposite direction.
= The driver moves the turn signal indicator in
the opposite direction.
= Active Distance Assist DISTRONIC or Active
Steering Assist is deactivated. =
The v ehicle cannot make the lane change as
planned.
Cancellation of Active Lane Change Assist is dis-
played as follows: = The arrow in the selected direction of travel
turns red.
= A corresponding message will also appear in
the driver's display.
= In certain circumstances a warning tone
sounds. &
WARNING Risk of accident when c
hanging
lane to an occupied adjacent lane
Lane Change Assist cannot always clearly
de
tect if the adjacent lane is free.
The lane change might be initiated although
the adjacent lane is not free. 
Before changing lanes, make sure that
t

he neighbouring lane is free and there is
no danger to other road users. 
Monitor the lane change. &
WARNING Risk of accident if Lane Chang
e
Assist unexpectedly stops functioning
If the system limitations for Lane Change
Assis
t have been reached, there is no guaran-
tee that the system will remain active.
Lane Change Assist cannot then assist you by
applying steering torque. 
Always monitor the lane change and
k

eep your hands on the steering wheel.
Observe the traPc conditions and steer
and/or brake if necessary. System limits
The sy

stem limitations of Active Steering Assist
apply to Active Lane Change Assist
(  page 259).
The system may also be impaired or may not func-
tion in the following situations:
= The sensors are damaged, covered or dirty
(  page 237).
= The exterior lighting shows a defect. 264

= The vehicle is on a construction site.
% The Active Lane Change Assist sensors adjust
aut

omatically while a certain distance is being
driven aser the vehicle has been delivered.
Active Lane Change Assist is unavailable or
only partially available during this teach-in
process, and no arrows are displayed next to
the Ø Active Steering Assist symbol.

Select Active Lane Change Assist. Active Brake Assist
Function of Active Brake Assist
A

ctive Brake Assist consists of the following func-
tions:
= Distance warning function
= Collision warning
= Autonomous braking function
= Situation-dependent braking assistance
= Vehicles with Driving Assistance Package and
Active Steering Assist: Evasive Steering Assist
Active Brake Assist can help you to minimise the
risk of a collision with vehicles, cyclists or pedes-
trians or to reduce the eMects of such a collision.
If Active Brake Assist has detected a risk of colli-
sion, a warning tone sounds and the / dis-
tance warning lamp lights up. In the Assistance
menu, an insuPcient dis
tance
1 to the vehicle in front is displayed in red. If you
further reduce the distance, the vehicle in front is
also highlighted in red. When the system detects a
risk of collision, red radar waves 2 appear in
front of the vehicle.
% Vehicles with PRE-SAFE n
: depending on t
he
country, an additional haptic warning occurs
in the form of slight, repeated tensioning of
the seat belt.
% Vehicles with active ambient lighting: if Warn-
ing assistance is activ
ated, the Active Brake
Assist warning is also accompanied by ambi-
ent lighting (  page 169). Driving and parking
265

If you do not react to the warning, autonomous
br
aking can be initiated in critical situations.
In particularly critical situations, Active Brake
Assist can also initiate autonomous braking
directly. In this case, the warning lamp and warn-
ing tone occur simultaneously with the braking
application.
If you apply the brake yourself in a critical situa-
tion or apply the brake during autonomous brak-
ing, situation-dependent braking assistance
occurs. The brake pressure increases up to maxi-
mum full-stop braking if necessary. If autonomous braking or situation-dependent
br

aking assistance has occurred, pop up 1appears in the driver's display and then automati-
call

y goes out aser a short time.
If the autonomous braking function or the situa-
tion-dependent braking assistance is triggered,
additional preventive measures for occupant pro-
tection (PRE-SAFE n
) may also be initiated. &
WARNING Risk of an accident caused b
y
limited detection performance of Active
Brake Assist
Active Brake Assist cannot always clearly iden-
tify objects and com
plex traPc situations.
In such cases, Active Brake Assist might:
= Give a warning or brake without reason
= Not give a warning or not brake
Active Brake Assist is only an aid. The driver is
responsible for maintaining a suPciently safe
distance to the vehicle in front, vehicle speed
and for braking in good time. 
Always pay careful attention to the tr
aPc
situation; do not rely on Active Brake
Assist alone. 
Be prepared to brake or swerve if neces-
sar

y. If Active Brake Assist is deactivated or the func-
tions ar
e restricted, e.g. due to activation of
another driving system, the ê display message
appears in the driver's display.
If the system is unavailable due to dirty or dam-
aged sensors or due to a fault, or if the functions
are restricted, the
