MERCEDES-BENZ GLB 2023 Owners Manual

=Vehicle steerability while braking is ensured.
If ABS intervenes when braking, you will feel a
pulsing in the brake pedal. The pulsating brake
pedal can be an indication of hazardous road con- ditions and can serve as a reminder to take extracare while driving.
System limits = ABS is active from speeds of approx. 3 mph
(5 km/h).
= ABS may be impaired or may not function if a
malfunction has occurred and the yellow %
ABS warning lamp lights up continuously aser
the vehicle is started.
Functions of OM-road ABS
\bOM-road ABS is activated automatically when
you select the ) drive program.
OM-road ABS is specially adapted for driving oM-
road:
= The front wheels lock cyclically during braking.
= The braking distance is shortened due to the
digging-in eMect.
System limits
= OM-road ABS functions at speeds below
25 mph (40 km/h).
= If OM-road ABS intervenes, the ability to steer
may be restricted.
Function of BAS
&WARNING Risk of an accident caused by a
malfunction in BAS (Brake Assist System)
If BAS is malfunctioning, the braking distance
in an emergency braking situation is
increased.
Depress the brake pedal with full force in
emergency braking situations. ABS pre-
vents the wheels from locking.
The Brake Assist System (BAS) supports your emergency braking situation with additional brakeforce.
If you depress the brake pedal quickly, BAS is
activated:
= BAS automatically boosts the brake pressure.
=BAS can shorten the braking distance.
= ABS prevents the wheels from locking.
The brakes will function as usual once you release the brake pedal. BAS is deactivated.

HOLD function

qHOLD function
The HOLD function holds the vehicle at a stand- still without requiring you to depress the brake pedal, e.g. while waiting in traPc.
The HOLD function is only an aid. The responsibil-
ity for the vehicle safely standing still remains with the driver.
System limits
The HOLD function is only intended to provide assistance when driving and is not a suPcient
means of safeguarding the vehicle against rolling
away when stationary.
= The incline must not be greater than 30%.

qActivating/deactivating the HOLD function&WARNING Risk of an accident due to the
HOLD function being active when you
leave the vehicle
If the vehicle is only braked with the HOLD
function it could, in the following situations,
roll away:
= If there is a malfunction in the system or in
the power supply.
= If the HOLD function is deactivated by
depressing the accelerator pedal or brake
pedal, e.g. by a vehicle occupant.
Always secure the vehicle against rolling away before you leave it.
Requirements

parking brake:
= The seat belt is unfastened and the driver\bs
door is opened.
= The vehicle is switched oM.
= There is a system malfunction.
= The power supply is insuPcient.
Function of Hill Start Assist
Hill Start Assist holds the vehicle for a short time
when you pull away on a hill under the following
conditions:
= The transmission is in position [ or ^.
= The electric parking brake is released.
This gives you enough time to move your foot
from the brake pedal to the accelerator pedal and
depress it before the vehicle begins to roll away.
&WARNING Risk of accident and injury due
to the vehicle rolling away
Aser a short time, Hill Start Assist no longer
holds the vehicle.
Swisly move your foot from the brake
pedal to the accelerator pedal. Do not
leave the vehicle when it is being held by
Hill Start Assist.
Start-oM assist

qFunction of the start-oM assist
The start-oM assist enables optimal vehicle accel-
eration from a standstill. For this, a suitably high-
grip road surface is required and the tires and
vehicle must also be in good condition.
Do not activate the start-oM assist on public
roads.
Be sure to observe the safety notes and informa-
tion on ESP n
( page 179).

qActivating the start-oM assist&WARNING Risk of skidding and having an
accident from wheels spinning
When you use start-oM assist, individual
wheels could spin and you could lose control
of the vehicle.
If ESP n
is deactivated, there is a risk of skid-
ding and accident!
Make sure that no persons or obstacles are in the close vicinity of your vehicle.Deactivating ESP n

Take your foot oM the brake, but keep the
accelerator pedal depressed.
The vehicle pulls away at maximum accelera-
tion.Switch on ESP n
once the acceleration proce-
dure is complete. ESP n
will otherwise not be
able to stabilize the vehicle if the vehicle starts
to skid or a wheel starts to spin.
Canceling the start-oM assist
Remove your foot from the accelerator pedal.Reactivate the ESP n
.
ATTENTION ASSIST

q Function of ATTENTION ASSIST
ATTENTION ASSIST assists you on long, monoto-
nous journeys, e.g. on highways and trunk roads.
If ATTENTION ASSIST detects indicators of fatigue
or increasing lapses in concentration on the part
of the driver, it suggests taking a break.
ATTENTION ASSIST is only an aid. It cannot
always detect fatigue or lapses in concentration in
time. The system is not a substitute for a well-res-
ted and attentive driver. On long journeys, take
regular breaks in good time that allow for ade-
quate 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 bewarned again aser a minimum of 15 minutes.
You can have the following status information for
ATTENTION 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
center 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.
184Driving and parking

If a warning is given in the Instrument Display, themultimedia system 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 37 mph
(60 km/h) to 124 mph (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).= If Active Steering Assist is activated and active
(  page 195).
= 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\bs door (e.g. to change drivers or take abreak).

Active Distance Assist DISTRONIC

q Function of Active Distance Assist DISTRONIC
DISTRONIC 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: = Vehicles without Driving Assistance Package:
15 mph (20 km/h) - 120 mph (200 km/h)
= Vehicles with Driving Assistance Package:
15 mph (20 km/h) - 130 mph (210 km/h)
Other features of Active Distance Assist
DISTRONIC:
= Adjusts the driving style depending on the
selected drive program (fuel-saving, comforta-
ble or dynamic)
= Initiates acceleration to the stored speed if the
turn signal indicator is switched on to change
to the overtaking lane
= Vehicles with Driving Assistance Package:
- Reacts to stationary vehicles detected in
urban speed ranges (except bicycles and
motorcycles)Driving and parking187

-Takes one-sided overtaking restrictions
into account on highways or on multi-lane
roads with separate roadways (country- dependent)
Vehicles with Driving Assistance Package and Parking Package: if the vehicle has been braked to
a standstill on multi-lane, separate roadways 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.
