XBriefly pull the cruise control lever towardsyou :.
XRemove your foot from the accelerator
pedal.
The first time cruise control is activated, it
stores the current speed or regulates the
speed of the vehicle to the previously
stored speed.
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 in 1 mph incre-
ments (1 km/h increments): briefly
press 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): brieflypress 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.
iCruise control is not deactivated if you
depress the accelerator pedal. If you accel- erate to overtake, cruise control adjusts
the vehicle's speed to the last speed stored
after you have finished overtaking.
Deactivating cruise control
There are several ways to deactivate cruise
control:
XBriefly press cruise the control lever for-
wards :.
or
XBrake.
Cruise control is automatically deactivated if:
Ryou engage the electric parking brake
Ryou are driving at less than 20 mph
(30 km/h)
RESP®intervenes or you deactivate ESP®
Ryou shift the transmission to position N
while driving
If cruise control is deactivated, you will hear a
warning tone. You will see the Cruise Con‐
trol Offmessage in the multifunction dis-
play for approximately five seconds.
iWhen you switch off the engine, the last
speed stored is cleared.

Continue todrive carefully and beready to
brake, inparticular when warned to dosoby
DI ST RONIC PLU S.
GWARNING
DI ST RONIC PLUS brakes your veh icle with up
to 50 %of the maximum possible deceleration.
If this braking force is insufficient, DISTRONIC
PLUS warns you visually and audibly. There is a risk of an accident.
In such cases, apply the brakes yourself and
try to take evasive action.
!If DISTRONIC PLUS or the HOLD function
is activated, the vehicle brakes automati-
cally in certain situations.
To prevent damage to the vehicle, deacti-
vate DISTRONIC PLUS and the HOLD func- tion in the following or other similar situa-
tions:
Rwhen towing the vehicle
Rin the car wash
If you fail to adapt your driving style,
DISTRONIC PLUS can neither reduce the risk
of accident nor override the laws of physics.
DISTRONIC PLUS cannot take into account
the road, traffic and weather conditions.
DISTRONIC PLUS 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.
Do not use DISTRONIC PLUS:
Rin road and traffic conditions which do not
allow you to maintain a constant speed e.g.
in heavy traffic or on winding roads
Ron slippery road surfaces. Braking or accel-
erating could cause the drive wheels to lose
traction and the vehicle could then skid
Rwhen there is poor visibility, e.g. due to fog,
heavy rain or snow
DISTRONIC PLUS may not detect narrow
vehicles driving in front, e.g. motorcycles, or
vehicles driving on a different line. In particular, the detection of obstacles can
be impaired if:
Rthere is dirt on the sensors or anything else
covering the sensors
Rthere is snow or heavy rain
Rthere is interference by other radar sources
Rthere are strong radar reflections, for
example, in parking garages
If DISTRONIC PLUS no longer detects a vehi- cle in front, DISTRONIC PLUS may unexpect-
edly accelerate the vehicle to the stored
speed.
This speed may:
Rbe too high if you are driving in a filter lane
or an exit lane
Rbe so high in the right lane that you pass
vehicles driving on the left (left-hand drive
countries)
Rbe so high in the left lane that you pass
vehicles driving on the right (right-hand
drive countries)
If there is a change of drivers, advise the new
driver of the speed stored.

Obstructions and stationary vehicles
DISTRONIC PLUS does not brake for obsta-
cles or stationary vehicles. If, for example, the
detected vehicle turns a corner and reveals
an obstacle or stationary vehicle, DISTRONIC
PLUS will not brake for these.
Crossing vehicles
DISTRONIC PLUS may mistakenly detect
vehicles that are crossing your lane. Activat-
ing DISTRONIC PLUS at traffic lights with
crossing traffic, for example, could cause
your vehicle to pull away unintentionally.
DISTRONIC PLUS with Steering Assist
and Stop&Go Pilot
General notes
DISTRONIC PLUS with Steering Assist and
Stop&Go Pilot aids you in keeping the vehicle
in the center of the driving lane by means of
moderate steering interventions at speeds of
0 - 125 mph (0 - 200 km/h).
It monitors the area in front of your vehicle by
means of camera system :at the top of the
windshield.
At speeds of 0 - 37 mph (0 - 60 km/h),
Stop&Go Pilot focuses on the vehicle in front,
taking into account lane markings, e.g. when
following vehicles in a traffic jam.
At speeds of more than 37 mph (60 km/h)
Steering Assist focuses on detected lane
markings (left and right), and only on the vehi-
cle in front if lane markings are missing.
Steering Assist and Stop&Go Pilot do not pro-
vide any support if these conditions do not
exist.
DISTRONIC PLUS must be active in order for
the function to be available.
Important safety notes
If you fail to adapt your driving style,
DISTRONIC PLUS with Steering Assist and
Stop&Go Pilot can neither reduce the risk of
an accident nor override the laws of physics. It cannot take account of road, weather and
traffic conditions. DISTRONIC PLUS with

MAGIC BODY CONTROL
General notes
MAGIC BODY CONTROL consists of Active
Body Control (ABC), ROAD SURFACE SCAN,
the CURVE cornering function as well as auto-
matic vehicle stabilization in the event of a
crosswind.
Your vehicle automatically adjusts its ride
height to reduce fuel consumption. The sus-
pension mode is adjusted according to your
selection (SPORT, COMFORT or CURVE), the
road surface conditions and the vehicle load.
A multifunction camera detects bumps in the
road surface before the vehicle drives over
them. This reduces chassis movements.
Important safety notes
GWARNING
When the vehicle is being lowered, people
could become trapped if their limbs are
between the vehicle body and the wheels or
underneath the vehicle. There is a risk of
injury.
Make sure no one is underneath the vehicle or
in the immediate vicinity of the wheel arches
when the vehicle is being lowered.
!The vehicle is lowered when the engine is
switched off. When parking, position your
vehicle so that it does not make contact
with the curb as the vehicle is lowered. Your
vehicle could otherwise be damaged.
Crosswind Assist
The crosswind stabilization operates by
changing wheel loads through distortion of
the ABC spring struts. It reduces impairments
in handling when driving in a straight line and
assists during countersteering. Crosswind Assist is active in the speed range
between 50 mph (80 km/h) and
130 mph (210 km/h) when driving straight
ahead or cornering gently.
Active Body Control ABC
Vehicle level
All vehicles except AMG vehicles:
depend-
ing on the vehicle level that has been set, the
vehicle automatically adjusts its height
dependent on the current speed. The vehicle
is lowered by up to 0.6 in (15 mm) as the
speed increases. As the speed is reduced, the
vehicle is raised up to the set vehicle height.
In the event of poor road surface conditions,
the vehicle automatically raises by up to 0.4 in
(10 mm) and harder damping is selected.
AMG vehicles: depending on the vehicle
level that has been selected, the vehicle auto-
matically adjusts its height dependent on the current speed. The vehicle is lowered by up to
0.4 in (10 mm) below the normal level as thespeed increases. As the speed is reduced, the
vehicle is raised up to the set vehicle height.
Select the "Normal" setting for normal road
conditions and "Raised" for driving with snow
chains or in particularly poor road conditions.
Your selection remains stored even if you
remove the SmartKey from the ignition lock.
The "Raised level" setting is canceled if you:
Rare driving faster than approximately
75 mph (120 km/h).
Rdrive for approximately three minutes at a
speed over 50 mph (80 km/h).
