between your vehicle and the vehicle in front
becomes too small.
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).
Stopping
GWARNING
When leaving the vehicle, even if it is braked
only by DISTRONIC PLUS, it could roll away if:
Rthere is a malfunction in the system or in
the voltage supply.
RDISTRONIC PLUS has been deactivated
with the cruise control lever, e.g. by a vehi-
cle occupant or from outside the vehicle.
Rthe electrical system in the engine com-
partment, the battery or the fuses have
been tampered with.
Rthe battery is disconnected.
Rthe 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.
For further information on deactivating
DISTRONIC PLUS (
Ypage 164).
If DISTRONIC PLUS detects that the vehicle in
front has stopped, it will cause your vehicle to
brake and come to a halt.
Once your vehicle is stationary, it remains sta-
tionary and you do not need to depress the
brake.
After a time, the electric parking brake secures
the vehicle and relieves 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
j,
if:
Rthe driver's seat belt is not fastened and the
driver's door is open.
Rthe engine is switched off, unless it is auto-
matically switched off by the ECO start/stop
function.
The electric parking brake secures the vehicle
automatically if DISTRONIC PLUS is activated
when the vehicle is stationary and:
Ra system malfunction occurs.
Rthe power supply is insufficient.
If a malfunction occurs, the transmission may
also be shifted to position jautomatically.
Setting a speed
XPush the cruise control lever up :for a
higher speed or down ;for a lower speed.
XTo adjust the set speed in 1 mph incre-
ments (1 km/h increments): briefly push
the cruise control lever up :or down ;to
the pressure point.
Every time the cruise control lever is pressed
up : or down ;the last speed stored is
increased or reduced.
XTo adjust the set speed in 5 mph incre-
ments (10 km/h increments): briefly push
the cruise control lever up :or down ;
beyond the pressure point.
Every time the cruise control lever is pressed
up : or down ;, the last speed stored is
increased or reduced.
iIf you accelerate to overtake, DISTRONIC
PLUS adjusts the vehicle's speed back to the
last speed stored after you have finished over-
taking.
Setting a specified minimum distance
You can set the specified minimum distance for
DISTRONIC PLUS by varying the time span
between one and two seconds. With this func-
tion, you can set the minimum distance that
DISTRONIC PLUS maintains to the vehicle in
front, depending on the driving speed. You can
see this distance in the multifunction display
(
Ypage 163).
Make sure that you maintain the minimum dis-
tance to the vehicle in front as required by law.

AIR BODY CONTROL
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 drive
fast, the vehicle is lowered automatically to
improve driving safety and to reduce fuel con-
sumption. There is also the option to manually
adjust 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 (
Ypage 134) or the level button
(Ypage 168). The setting always corresponds
to the last selected function.

Suspension tuning
General notes
The Adaptive Damping System automatically
controls the calibration of the dampers.
The damping is tuned individually to each wheel
and depends on:
Ryour driving style, e.g. sporty
Rthe road surface condition, e.g. bumps
Ryour individual selection, i.e. sports or com-
fort
Your selection remains stored even if you
remove the SmartKey from the ignition lock.
Sports tuning
In the "Sport" and "Sport Plus" drive programs,
the firmer suspension setting ensures even bet-
ter contact with the road. Select this mode when
employing a sporty driving style, e.g. on winding country roads.
XSelect the Sor S+ drive program with the
DYNAMIC SELECT switch (Ypage 134).
The vehicle is lowered by 0.6 in (15 mm) com- pared to the normal level.
Each time you restart the engine, the vehicle is
raised to normal level again and drive program C
is activated. For further information about start-
ing the engine, see (
Ypage 128).
Comfort tuning
In the "Eco" and "Comfort" drive programs, the
driving characteristics of your vehicle are more
comfortable. Therefore, select this mode if you
favor a more comfortable driving style. Select

GLC 43 4MATIC Coupe)
General notes
The electronically controlled damping system
works continuously. This improves driving
safety and ride comfort.
The damping is tuned individually to each wheel
and depends on:
Ryour driving style, e.g. sporty
Rthe road surface condition, e.g. bumps
Ryour individual selection of Sport, Sport+ or
Comfort
The suspension setting is adjusted using the
corresponding button in the center console.
iThe mode can also be set using the
DYNAMIC SELECT switch (Ypage 134).
This is possible only if the same mode is
selected for the suspension by pressing the
button on the center console for AMG sports
suspension based on AIR BODY CONTROL
and the DYNAMIC SELECT switch. This is the
case, for example, when both are set to Com- fort mode.
Each time you start the engine with the Smart-
Key or the Start/Stop button, Comfort mode is
activated. For further information about starting
the engine, see (

Active Parking Assist will only detect parking
spaces:
Rparallel or at right angles to the direction of
travel
Rthat are parallel to the direction of travel and
at least 59 in (1.5m) wide
Rthat are parallel to the direction of travel and
at least 39.5 in (1.0 m)longer than your vehi-
cle
Rat right angles to the direction of travel and at
least 39.5 in (1.0 m) wider than your vehicle
iNote that Active Parking Assist cannot
measure the size of a parking space if it is at
right angles to the direction of travel. You will need to judge whether your vehicle will fit into
the parking space.
When driving at speeds below 19 mph
(30 km/h), you will see parking symbol ;as a
status indicator in the instrument cluster. When
a parking space has been detected, an arrow
towards the right or the left also appears. By
default, Active Parking Assist only displays park-
ing spaces on the front-passenger side. Parking
spaces on the driver's side are displayed as
soon as the turn signal on the driver's side is
activated. When parking on the driver's side,
this must remain switched on until you acknowl-
edge the use of Active Parking Assist by press-
ing the abutton on the multifunction steer-
ing wheel. The system automatically determines
whether the parking space is parallel or at right
angles to the direction of travel.
A parking space is displayed while you are driv-
ing past it, and until you are approximately 50 ft
(15 m) away from it.
