2022 MERCEDES-BENZ GLE COUPE Owners Manual

Function of Active Speed Limit Assist
If a c
hange in the speed limit of 20 km/h or more
is detected and automatic adoption of speed lim-
its is activated, the new speed limit is automati-
cally adopted as the stored speed (  page 269).
The driven speed is adjusted when the vehicle is
level with the traPc sign at the latest. In the case
of signs indicating entry into an urban area, the
speed is adapted according to the speed permit-
ted within the urban area. The speed limit display
in the Instrument Display is always updated when
the vehicle is level with the traPc sign.
If there is no speed restriction on an unlimited
stretch of road (e.g. on a motorway), the recom-
mended speed is automatically adopted as the
stored speed. The system uses the speed stored
on an unlimited stretch of road as the recommen-
ded speed. If you do not alter the stored speed on
an unlimited stretch of road, the recommended
speed is 130 km/h.
If Active Distance Assist DISTRONIC has been put
into passive mode by pressing the accelerator
pedal, only speed limits which are higher than the
set speed are adopted. Observe the notes on driving systems and your
r
esponsibility; you may otherwise fail to recognise
dangers (  page 237).
System limits
The system limits of TraPc Sign Assist apply to
the detection of traPc signs ( page 267).
Speed limits below 20 km/h are not automatically
adopted by the system as the stored speed. Tem-
porary speed restrictions (e.g. for a certain time
or due to weather conditions) cannot be properly
detected by the system. The maximum permissi-
ble speed applying to a vehicle with a trailer is not
detected by the system.
Adjust the speed in these situations. &

speed
The speed adopted by Active Speed Limit
Assis
t may be too high or incorrect in some
individual cases, such as:
= at speed limits below 20 km/h =
in w
et conditions or in fog
= when towing a trailer 
Ensure that the driven speed complies
wit

h traPc regulations. 
Adjust the driving speed to suit current
tr
aPc and weather conditions. Function of route-based speed adaptation
When A

ctive Distance Assist DISTRONIC is activa-
ted, the vehicle speed will be adapted accordingly
to the route events ahead. Depending on the drive
program selected, the vehicle negotiates a route
event ahead in an economical, comfortable or
dynamic manner. When the route event has been
passed, the vehicle accelerates again to the
stored speed. The set distance to the vehicle in
front, vehicles detected ahead and speed restric-
tions ahead are taken into account.
You can activate and deactivate route-based
speed adaptation in the multimedia system
(  page 255).
The following route events are taken into account: = Bends 254
Driving and parking

=
T -junctions, roundabouts and toll stations
= Turns and exits
= TraPc jams ahead (only with Live TraPc Infor-
mation )
% When the toll station is reached, Active Dis-
t
ance Assist DISTRONIC adopts the speed as
the stored speed.
Also, the speed is reduced if the turn signal indi-
cat
or to change lanes is switched on and one of
the following situations is detected:
= Turning at junctions
= Driving on slowing-down lanes
= Driving on lanes adjacent to slowing-down
lanes
The driver is responsible for choosing the right
speed and observing other road users. This
applies in particular to junctions, roundabouts and
traPc lights, as route-based speed adaptation
does not brake the vehicle to a standstill.
When route guidance is active, the Nrst speed
adjustment is carried out automatically. If the turn
signal indicator is switched on, the selected route is conNr
med
and further speed adjustment is acti-
vated.
Speed adaptation is cancelled in the following
cases:
= If the turn signal indicator is switched oM
before the route event.
= If the driver depresses the accelerator or
brake pedal during the process.
System limits
Route-based speed adaptation does not take right
of way regulations into account. The driver is
responsible for complying with road traPc regula-
tions and driving at a suitable speed.
The speed adaptation made by the system may
not always be suitable, particularly in the following
situations:
= the road's course not clearly visible
= Road narrowing
= varying maximum permissible speeds in indi-
vidual lanes, forexample at toll stations
= wet road surfaces, snow or ice
= when towing a trailer In these situations the driver must intervene
accor
dingly. &
WARNING Risk of accident in spit

Route-based speed adaptation can malfunc-
tion or be t
emporarily unavailable in the fol-
lowing situations:
= If the driver does not follow the calculated
route
= If map data is not up-to-date or available
= In the event of roadworks

Function of Active Stop-and-Go Assist
A
ctive Stop-and-Go Assist helps you when in traf-
fic jams on multi-lane roads with separate carria-
geways by automatically pulling away within up to
60 seconds and with moderate steering manoeu-
vres. It orients itself using the vehicle in front and
lane markings. Active Stop-and-Go Assist auto-
matically maintains a safe distance from the vehi-
cle in front and vehicles cutting in.
Active Stop-and-Go Assist requires you, as the
driver, to keep your hands on the steering wheel
at all times so that you are able to intervene at
any time to correct the course of the vehicle and keep it in lane. Observe the notes on driving sys-
t
ems and your responsibility; you may otherwise
fail to recognise dangers ( page 237).
Active TraPc Jam Assist activates automatically as
soon as all of the requirements are met: The

tus indicator in the multifunction display disap-

Information on DSR &
WARNING Risk of skidding and accident
when DSR is activ
ated on slippery road
surfaces
If the driven speed and the target speed diMer
,
the wheels may lose traction. 
Take into account the road surface and
t
he diMerence between the driving speed
and target speed before activating DSR. Observe the notes on driving systems and your
r
esponsibility; you may otherwise fail to recognise
dangers ( page 237).
You are always responsible for keeping control of
the vehicle and for assessing whether the downhill
gradient can be negotiated. Depending on road
surface and tyres, DSR may not always be able to
keep to the target speed. Select a target speed
suitable for the environmental conditions and also
apply the brakes yourself if required. Activating/deactivating DSR (vehicles with E-

Function of Active Steering Assist
A

ctive Steering Assist is only available up to a
speed of 210 km/h. The system helps you to stay
in the centre of the lane by means of moderate
steering interventions. Depending on the speed
driven, Active Steering Assist uses the vehicles
ahead and lane markings as a reference.
% Depending on the country, in the lower speed
r
ange Active Steering Assist can use the sur-
rounding traPc as a reference. If necessary,
Active Steering Assist can then also provide
assistance when driving outside the centre of
the lane, forexample, to form a rescue lane.
If the detection of lane markings and vehicles
ahead is im
paired, Active Steering Assist switches
to passive mode. The system provides no support
in this case.

Steering and touch detection
The dr
iver is required to keep their hands on the
steering wheel at all times and be able to inter-
vene at any time to correct the course of the vehi-
cle and keep it in lane. The driver must expect a
change from active to passive mode or vice versa
at any time. If the system detects that the driver has not
s
teered the vehicle for a considerable period of
time or has removed their hands from the steering
wheel, display 1 appears. If the driver still does
not steer the vehicle, a warning tone sounds in
addition to the visual warning message.
If the driver does not react to the warning for a
considerable period, the system can initiate an
emergency stop ( page 260).
The warning is not issued or is stopped when the
driver gives conNrmation to the system:
= The driver steers the vehicle. =
Depending on t
he country: the driver presses
a steering wheel button or operates Touch
Control
If Active Steering Assist detects that a system
limit has been reached, a visual warning is issued
and a warning tone sounds.
Observe the notes on driving systems and your
responsibility; you may otherwise fail to recognise
dangers (  page 237).
System limits
Active Steering Assist has a limited steering tor-
que for lateral guidance. In some cases, the steer-
ing intervention is not suPcient to keep the vehi-
cle in the lane or to drive through exits.
The system may be impaired or may not function
in the following instances:
= There is poor visibility, e.g. due to snow, rain,
fog, heavy spray, greatly varying light condi-
tions or strong shadows on the carriageway.
= There is glare, e.g. from oncoming traPc,
direct sunlight or reOections.

quickly, forexample, in a construction area or
junctions.
= The lane markings are worn away, dark or cov-
ered up, e.g. by dirt or snow.
= If the distance to the vehicle in front is too
short and thus the lane markings cannot be
detected.

stages to a standstill.
Depending on the country, at speeds below
60 km/h the hazard warning lights switch on
automatically.
When the vehicle is stationary, the following
actions are carried out:
= The vehicle is secured with the electric park-

Function of Active Brake Assist
A

ctive Brake Assist consists of the following func-
tions:
= Distance warning function
= Autonomous braking function
= Situation-dependent braking assistance
= Vehicles with Driving Assistance Package: Eva-
sive Steering Assist and cornering function
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 instrument
clus
ter.
Vehicles with PRE-SAFE n
: depending on the coun-
try, an additional haptic warning occurs in the
form of slight, repeated tensioning of the seat
belt.
If you do not react to the warning, autonomous
braking can be initiated in critical situations.
In especially critical situations, Active Brake Assist
can initiate autonomous braking directly. In this
case, the warning lamp and warning 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.
