2016 MERCEDES-BENZ GLC COUPE belt

Vehicles with COMAND Online multimedia
system: when you change lanes, DISTRONIC
PLUS monitors the right lane in the case of left-
side traffic or the left lane in the case of right-
side traffic.
Vehicles with Audio 20 multimedia system:
when you change lanes, DISTRONIC PLUS mon- itors the left lane on left-hand-drive vehicles or
the right lane on right-hand-drive vehicles.
Road and traffic conditions The following function is available only in vehi-
cles with the Driving Assistance Plus package.
The function is not operational in all countries.
DISTRONIC PLUS uses additional information
from your navigation system so that it can adapt to certain traffic situations.
This is the case if, while you are following a vehi-
cle, DISTRONIC PLUS is active and you:
R approach or drive around a roundabout
R approach a T-junction
R turn off at a motorway exit
R approach a tollgate
Even if the vehicle in front leaves the detection
range, DISTRONIC PLUS temporarily maintains
the current driving speed and does not acceler-
ate. This is based on the current map data in the navigation system.
Afterwards, the vehicle accelerates back to the
speed you set.
The system takes into account the fact that
overtaking on the right is not permitted on
motorways or high-speed major roads at speeds
of more than 80 km/h. The driving speed is
adjusted to the speed of the queue of vehicles in
the adjacent lane to the left.
Prevention of overtaking on the right applies to
countries where traffic drives on the right. In
countries where traffic drives on the left, over-
taking on the left is prevented accordingly. Stopping G
WARNING
When leaving the vehicle, even if it is braked
only by DISTRONIC PLUS, it could roll away if:
R there is a malfunction in the system or in
the voltage supply.
R DISTRONIC PLUS has been deactivated
with the cruise control lever, e.g. by a vehi-
cle occupant or from outside the vehicle.
R the electrical system in the engine com-
partment, the battery or the fuses have
been tampered with.
R the battery is disconnected.
R the accelerator pedal has been depressed,
e.g. by a vehicle occupant.
There is a risk of an accident.
If you wish to exit the vehicle, always turn off
DISTRONIC PLUS and secure the vehicle
against rolling away.
Further information on deactivating DISTRONIC PLUS (Y page 183).
If DISTRONIC PLUS detects that the vehicle in
front has stopped, it will cause your vehicle to
brake to a standstill.
Once your vehicle is stationary, it remains sta-
tionary and you do not need to depress the
brake.
After a short period, the vehicle is secured by
the electric parking brake, thus relieving the
service brake.
Depending on the specified minimum distance,
your vehicle will come to a standstill at a suffi-
cient distance behind the vehicle in front. The
specified minimum distance is set using the
control on the cruise control lever.
When DISTRONIC PLUS is activated, the trans-
mission is shifted automatically to position Pin
the following situations:
R the driver's seat belt is not fastened and the
driver's door is open
R The engine is switched off, unless it is auto-
matically switched off by the ECO start/stop
function Driving systems

General notes The HOLD function can assist the driver in the
following situations:
R when pulling away, especially on steep slopes
R when manoeuvring on steep slopes
R when waiting in traffic
The vehicle is kept stationary without the driver having to depress the brake pedal.
The braking effect is cancelled and the HOLD
function deactivated when you depress the
accelerator pedal to pull away. Important safety notes G
WARNING
When leaving the vehicle, it can still roll away despite being braked by the HOLD function if:
R there is a malfunction in the system or in
the voltage supply
R the HOLD function is deactivated by the
accelerator pedal being depressed, e.g. by
a vehicle occupant
R the electrical system in the engine com-
partment, the battery or the fuses are tam-
pered with
R the battery is disconnected
There is a risk of an accident.
Before leaving the vehicle, always deactivate
the HOLD function and secure the vehicle
from rolling away.
! When DISTRONIC PLUS or the HOLD func-
tion is activated, the vehicle brakes automat- ically in certain situations.
To avoid damage to the vehicle, deactivate
DISTRONIC PLUS and the HOLD function in
the following or similar situations:
R when towing away
R in a car wash

General notes AIR BODY CONTROL is an air suspension system
with variable damping for improved driving com-
fort. All-round level control ensures the best
possible suspension and constant ground clear- ance, even with a laden vehicle. When you driveat speed, the vehicle is lowered automatically to improve driving safety and to reduce fuel con-
sumption. You also have the option of manually
adjusting the vehicle level. AIR BODY CONTROL
consists of level setting, level control and the
ADS Adaptive Damping System.
The vehicle level can be set using the DYNAMIC SELECT switch (Y page 152) or the level button
(Y page 188). The setting always corresponds
to the last function selected.
Important safety notes G
WARNING
People's limbs may become trapped if they
are located underneath the vehicle or
between the vehicle body and the tyres when the vehicle is lowering. There is a danger of
injury.
When lowering the vehicle, make sure no one
is underneath the vehicle or in the immediate vicinity of the wheel arches.
i If one of the doors is open, the vehicle is not
lowered. Driving systems

ATTENTION ASSIST
General notes ATTENTION ASSIST helps you during long,
monotonous journeys such as on motorways
and trunk roads. It is active in the 60 km/h to
200 km/h speed range. If ATTENTION ASSIST
detects typical indicators of fatigue or increas-
ing lapses in concentration on the part of the
driver, it suggests taking a break.
Important safety notes ATTENTION ASSIST is only an aid. It may not
always detect fatigue or lapses in concentration
until too late, or may not detect them at all. The system is not a substitute for a well-rested and
attentive driver.
The functionality of ATTENTION ASSIST is
restricted, and warnings may be delayed or not
occur at all in the following situations:
R if the length of the journey is less than approx-
imately 30 minutes
R if the road condition is poor, e.g. if the surface
is uneven or contains potholes
R in case of strong side winds
R if you have adopted a sporty driving style with
high cornering speeds or high rates of accel-
eration
R if you are predominantly driving at a speed
below 60 km/h or above 200 km/h
R if you are driving with DISTRONIC PLUS Steer-
ing Assist activated
R if the time has been set incorrectly
R in active driving situations, such as when you
change lanes or change your speed
The ATTENTION ASSIST tiredness assessment
is deleted and restarted when you continue the
journey in the following situations:
R you switch off the engine
R you take off your seat belt and open the driv-
er's door, e.g. for a change of drivers or to
take a break Displaying the attention level In the Assistance menu (Y
page 240) of the on-
board computer, you can call up the current sta-
tus information.
X Select the assistance graphic display for
ATTENTION ASSIST using the on-board com-
puter (Y page 239).
The following information appears:
R the length of the journey since the last break
R the attention level determined by ATTENTION
ASSIST (Attention level Attention level), displayed in a
bar display in five levels from high to low
R if ATTENTION ASSIST is unable to calculate
the attention level and cannot issue a warn-
ing, the System suspended System suspended message
appears. The bar display then changes the
display, e.g. if you are driving at a speed below 60 km/h or above 200 km/h
Activating ATTENTION ASSIST X
Activate ATTENTION ASSIST using the on-
board computer (Y page 242).
The system determines the attention level of
the driver depending on the setting selected:
If Standard Standard is selected: the sensitivity with
which the system determines the attention level
is set to normal.
If Sensitive
Sensitive is selected: the sensitivity is set
higher. The attention level detected by ATTEN-
TION ASSIST is adapted accordingly and the
driver is warned earlier.
When ATTENTION ASSIST is deactivated, the
é symbol appears on the multifunction dis-
play in the assistance graphic when the engine is running.
When ATTENTION ASSIST has been deactivated,
it is automatically reactivated after the engine
has been switched off. The sensitivity selected Driving systems

Some systems carry out a self-diagnosis when the ignition is switched on. In the process, several
warning and indicator lamps may temporarily light up or flash. This is not an indication of any
problem. These warning and indicator lamps only indicate a malfunction if they light up or flash after
the engine is started or during a journey. Safety
