Dynamic control MERCEDES-BENZ CLA-Class 2017 C117 User Guide

If Distance Pilot DISTRONIC detects a faster-
moving vehicle in front, it increases the driving
speed. However, the vehicle is only accelerated
up to the speed you have stored.
iDistance Pilot DISTRONIC is deactivated
when you depress the brake, except when the vehicle is stationary.
Selecting the drive program
Distance Pilot DISTRONIC supports a sporty
driving style when you select the S+drive pro-
gram (Mercedes-AMG vehicles only), S
(
Ypage 133) or the manual drive program
(Ypage 135). Acceleration behind the vehicle in
front or to the set speed is then noticeably more
dynamic. If you have selected the E(Mercedes-
AMG vehicles: C) drive program, the vehicle
accelerates more gently. This setting is recom-
mended in stop-and-start traffic.
Changing lanes
If when driving on multilane roads you wish to
change to the overtaking lane, Distance Pilot
DISTRONIC supports you if:
Ryou are driving faster than 45 mph (70 km/h)
RDistance Pilot DISTRONIC is maintaining the
distance to a vehicle in front
Ryou switch on the appropriate turn signal
RDistance Pilot DISTRONIC does not currently
detect a danger of collision
If these conditions are fulfilled, your vehicle is
accelerated. Acceleration will be interrupted if
changing lanes takes too long or if the distance
between your vehicle and the vehicle in front
becomes too small.
Stopping
If Distance Pilot DISTRONIC detects that the
vehicle in front is stopping, it brakes your vehicle
until it is stationary.
Once your vehicle is stationary, it remains sta-
tionary and you do not need to depress the
brake.
iAfter a time, the electric parking brake
secures the vehicle and relieves the service
brake.
iDepending on the specified minimum dis-
tance, your vehicle will come to a standstill at a sufficient distance behind the vehicle in
front. The specified minimum distance is set
using the control on the cruise control lever. When Distance Pilot DISTRONIC is activated,
the transmission is shifted automatically to
position
Pif:
Rthe driver's seat belt is not fastened and the
driver's door is open.
Rthe engine is switched off, u nless it is auto-
matically switched off by the ECO start/stop
function.
The electric parking brake secures the vehicle
automatically if Distance Pilot DISTRONIC 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 shift into position Pautomatically.
Setting a speed
Keep in mind that it may take a brief moment
until the vehicle has accelerated or braked to
the speed set.
XPress the cruise control lever up :for a
higher speed or down ;for a lower speed.
XTo adjust the set speed in1 mphincre-
ments (1 km/hincrements): briefly press
the cruise control lever up :or down ;to
the pressure point.
The last stored speed increases or decreases in 1 mph (1 km/h) increments.
XTo adjust the set speed in5 mphincre-
ments (10 km/hincrements): briefly press
the cruise control lever up :or down ;to
the pressure point.
The last stored speed increases or decreases in 5 mph (10 km/h) increments.
iDistance Pilot DISTRONIC is not deactivated
if you depress the accelerator pedal. If you
accelerate to overtake, Distance Pilot
DISTRONIC adjusts the vehicle's speed to the
last speed stored after you have finished over- taking.
Setting a specified minimum distance
You can set the specified minimum distance for
Distance Pilot DISTRONIC by varying the time
span between one and two seconds. With this
function you can set the minimum distance that
Distance Pilot DISTRONIC maintains to the vehi-
cle in front, dependent on vehicle speed. You
can see this distance in the multifunction dis-
play (
Ypage 154).

AMG adaptive sport suspension sys-
tem
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" or "Com-
fort"
The suspension setting is adjusted using the
corresponding button in the center console.
iThe mode can also be set using the AMG
DYNAMIC SELECT controller (Ypage 128).
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 (
Ypage 122).

The firmer setting of the suspension tuning in

the road. Select this mode when employing a
sporty driving style, e.g. on winding country
roads.

4MATIC
!
Never tow the vehicle with one axle raised.
This may damage the differential. Damage of
this sort is not covered by the Mercedes-Benz
Limited Warranty. All wheels must remain
either on the ground or be fully raised.
Observe the instructions for towing the vehi-
cle with all wheels in full contact with the
ground.
4MATIC, together with ESP
®, improves the trac-
tion of your vehicle whenever a drive wheel
spins due to insufficient grip.
If you fail to adapt your driving style, 4MATIC can neither reduce the risk of accident nor override
the laws of physics. 4MATIC cannot take
account of road, weather and traffic conditions.
4MATIC is only an aid. You are responsible for
the distance to the vehicle in front, for vehicle
speed, for braking in good time and for staying in
your lane.
If a drive wheel spins due to insufficient grip:
ROnly depress the accelerator pedal as far as
necessary when pulling away.
RAccelerate less when driving.
iIn wintry driving conditions, the maximum
effect of 4MATIC can only be achieved if you
use winter tires (M+S tires), with snow chains
if necessary.
Suspension with Adaptive Damping
System
General notes
A suspension with the Adaptive Damping Sys-
tem provides improved driving comfort and con-
tinuously controls the calibration of the damp-
ers. The damping characteristics adapt to the
current operating and driving situation.
The damping is tuned individually to each wheel
and depends on:
Ryour driving style, e.g. sporty
Rthe road surface conditions
Rthe drive program selected
The drive program can be set using the
DYNAMIC SELECT button (
Ypage 127).
Selecting Comfort mode
In the Comfort drive program, the driving char-
acteristics of your vehicle are more comforta-
ble. Therefore, select this drive program if you
prefer a more comfortable driving style. Also
select the Comfortdrive program when driving
fast on straight roads, e.g. on straight stretches of highway.
XPress DYNAMIC SELECT button (Ypage 127)
as many times as necessary until the Com-
fort drive program is selected.
Selecting Sport mode
The firmer setting of the suspension tuning in
theSport drive program ensures even better
contact with the road. Select this drive program
when employing a sporty driving style, e.g. on
winding country roads.
