MERCEDES-BENZ GLS SUV 2022 Owners Manual


Depress the brake pedal until the

regular breaks in good time that allow for ade-
q
uate recuperation.
You can choose between two settings:
= Standard: normal system sensitivity.
= Sensitive: higher system sensitivity. The driver
is warned earlier and the attention level detec-
ted by ATTENTION ASSIST is adapted accord-
ingly.
If drowsiness or increasing lapses in concentra-
tion are detected, the ATTENTION ASSIST Take
a break! warning appears in the Instrument Dis-
play. You can acknowledge the message and take
a break where necessary. If you do not take a
break and ATTENTION ASSIST continues to detect
increasing lapses in concentration, you will be
warned again aser a minimum of 15 minutes. You can have the following status information for
A

TTENTION ASSIST displayed in the assistance
menu of the on-board computer:
= The length of the journey since the last break.
= The attention level determined by ATTENTION
ASSIST:
- the fuller the circle, the higher the atten-
tion level determined
- as your attention wanes, the circle in the
centre of the display becomes smaller
If ATTENTION ASSIST is unable to calculate the
attention level and cannot issue a warning, the
System suspended message appears. If a warning is given in the Instrument Display, the
multimedia sy
stem oMers to search for a rest
area. You can select a rest area and start naviga-
tion to this rest area. This function can be activa-
ted and deactivated in the multimedia system.
If ATTENTION ASSIST is deactivated, the Û
symbol appears in the assistance graphic in the
Instrument Display. Aser the vehicle is started,
ATTENTION ASSIST is automatically activated. The
last selected sensitivity level remains stored.
System limits
ATTENTION ASSIST is active in the 60 km/h to
200 km/h speed range.
Particularly in the following situations, ATTENTION
ASSIST only functions in a restricted manner and
warnings may be delayed or not occur:
= If you have been driving for less than approx-
imately 30 minutes.
= If the road condition is poor (uneven road sur-
face or potholes).
= If there is a strong side wind.
= If you adopt a sporty driving style (high corner-
ing speeds or high rates of acceleration). Driving and parking

=
If A ctive Steering Assist is activated and active
( page 252).
= If the time has been set incorrectly.
= If you change lanes and vary your speed fre-
quently in active driving situations.
The ATTENTION ASSIST drowsiness or alertness
assessment is reset and restarted when continu-
ing the journey in the following situations:
= If you switch oM the vehicle.
= If you unfasten your seat belt and open the
driver's door (e.g. to change drivers or take a
break).

Function of cruise control
Cr

uise control regulates the speed to the value
selected by the driver.
If you accelerate to overtake, forexample, the
stored speed is not deleted. If you remove your
foot from the accelerator pedal aser overtaking,
cruise control will resume speed regulation back
to the stored speed.
You can store any speed above 20 km/h up to the
maximum design speed or up to the set winter
tyre limit. When driving in LOW RANGE oM-road
gear, the adjustable speed is reduced
(  page 215). Observe the notes on driving systems and your
r

esponsibility; you may otherwise fail to recognise
dangers ( page 231).

will make use of the engine's braking
eMect. This
r elieves the load on the brake system and pre-
vents the brakes from overheating and wearing
too quickly.
Do not use cruise control in the following situa-
tions:
= in traPc situations which require frequent
changes of speed, e.g. in heavy traPc, on
winding roads
= on slippery roads. Accelerating can cause the
drive wheels to lose traction and the vehicle
could then skid.
= when visibility is poor
Function of the limiter
The limiter restricts the speed of the vehicle. To
reduce the speed to the set speed, the limiter
applies the brakes automatically.
You can limit the speed as follows:
= Variable: for a short-term speed restriction,
e.g. in built-up areas
= Permanent: for a longer-term speed restric-
tion, e.g. in winter tyre mode You can store any speed above 20 km/h up to the
maximum design speed or up t
o the set winter
tyre limit. You can also perform settings while the
vehicle is stationary if the vehicle has been star-
ted.
Observe the notes on driving systems and your
responsibility; you may otherwise fail to recognise
dangers ( page 231).

Information on the permanent limiter
If t
he vehicle should never exceed a speciNc
speed (e.g. for driving in winter tyre mode), you
can set this speed with the permanent limiter.
You do this by limiting the speed between
160 km/h and 240 km/h in the multimedia sys-
tem ( page 243).
Shortly before the set speed is reached, it
appears in the Instrument Display. When you con-
Nrm the message, display messages no longer
appear until you switch oM the vehicle. The speed will only be displayed again once the vehicle has
been r

estarted or if the set speed is changed.
The permanent limiter does not switch to passive
mode even during kickdown and the driven speed
remains below the set speed.

Function of Active Distance Assist DISTRONIC

TRONIC Active Distance Assist maintains the
set speed when driving freely. If vehicles are
detected ahead, the set distance is maintained, if
necessary until the vehicle comes to a standstill.
The vehicle accelerates or brakes depending on
the distance to the vehicle in front and the set
speed. The speed and distance to the vehicle in
front are set and saved using the steering wheel. Available speed range:
= V

Vehicles with Driving Assistance Package and
P
arking Package: if the vehicle has been braked to
a standstill on multi-lane, separate carriageways
by Active Distance Assist DISTRONIC, it can auto-
matically follow the vehicle in front when driving
oM again within 30 seconds. If a critical situation
is detected when driving oM, a visual and acoustic
warning is given indicating that the driver must
now take control of the vehicle. The vehicle is not
accelerated any further.
