Page 179 of 382

Narrow vehicles
DISTRONIC PLUS has not yet detected the vehi-
cle in front on the edge of the road, because of
its narrow width. The distance to the vehicle in
front will be too short.
Obstructions and stationary vehicles
DISTRONIC PLUS does not brake for obstacles
or stationary vehicles. If, for example, the detec-
ted vehicle turns a corner and reveals an obsta-cle or stationary vehicle, DISTRONIC PLUS will
not brake for these.
Crossing vehicles
DISTRONIC PLUS may mistakenly detect vehi-
cles that are crossing your lane. Activating 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 mod-
erate 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 vehi-
cles in a traffic jam.
At speeds of more than 37 mph (60 km/h)
Steering Assist focuses on detected lane mark-
ings (left and right), and only on the vehicle 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 Steering Assist and
Stop&Go Pilot is only an aid. You are respo nsible
fo
r the distance to the vehicle in front, for vehi-
cle speed, for braking in good time and for stay-
ing in your lane.
Driving system s177

Page 180 of 382

DISTRONIC PLUS with Steering Assist and
Stop&Go Pilot does not detect road and traffic
conditions. If you are following a vehicle which is
driving towards the edge of the road, your vehi-
cle could come into contact with the curb or
other road boundaries. Be particularly aware of
other road users, e.g. cyclists, that are directly
next to your vehicle.
Obstacles such as traffic pylons on the lane or
projecting out into the lane are not detected.
An inappropriate steering intervention, e.g. after
intentionally driving over a lane marking, can becorrected at any time if you steer slightly in the
opposite direction.
DISTRONIC PLUS with Steering Assist and
Stop&Go Pilot cannot continuously keep your
vehicle in lane. In some cases, the steering
intervention is not sufficient to bring the vehicle
back to the lane. In such cases, you must steer
the vehicle yourself to ensure that it does not
leave the lane.
The support provided by the system can be
impaired if:
Rthere is poor visibility, e.g. due to insufficient
illumination of the road, or due to snow, rain,
fog or spray
Rthere is glare, e.g. from oncoming traffic, the
sun or reflections (e.g. when the road surface
is wet)
Rthe windshield is dirty, fogged up, damaged or
covered, for instance by a sticker, in the vicin-
ity of the camera
Rthere are no, several or unclear lane markings
for a lane, e.g. in areas with road construction
work
Rthe lane markings are worn away, dark or cov-
ered up, e.g. by dirt or snow
Rthe distance to the vehicle in front is too small
and the lane markings thus cannot be detec-
ted
Rthe lane markings change quickly, e.g. lanes
branch off, cross one another or merge
Rthe road is narrow and winding
Rthere are strong shadows cast on the road
The system is switched to passive and no longer
assists you by performing steering interventions
if:
Ryou actively change lane
Ryou switch on the turn signal
Rtake your hands off the steering wheel or do
not steer for a prolonged period of time
iSteering Assist and Stop&Go Pilot are acti-
vated again automatically after a lane change
is completed.
Steering Assist and Stop&Go Pilot do not pro-
vide any support:
Ron very sharp corners
Rwhen a loss of tire pressure or a defective tire
has been detected and displayed
Pay attention also to the impo
rtant safety notes
for DISTRONIC PLUS (Ypage 171).
The steering interventions are carried out with a
limited steering moment. The system requires
the driver to keep his hands on the steering
wheel and to steer himself.
If you do not steer yourself or if you take your
hands off the steering wheel for a prolonged
period of time, the system will first alert you with
a visual warning. A steering wheel symbol
appears in the multifunction display. If you have
still not started to steer and have not taken hold
of the steering wheel after five seconds at the
latest, a warning tone also sounds to remind you
to take control of the vehicle. Steering Assist
and Stop&Go Pilot are switched to passive.
DISTRONIC PLUS remains active.
Activating Steering Assist and Stop&Go
Pilot
XActivate the DISTRONIC PLUS with Steering
Assist and Stop&Go Pilot function using the

DSR (Downhill Speed Regulation)
General notes
DSR is an aid to assist you when driving down-
hill. It keeps the speed of travel at the speed
selected on the on-board computer. The steeper
the downhill gradient, the greater the DSR brak-
ing effect on the vehicle. When driving on flat
stretches of road or on an uphill gradient, the
DSR braking effect is minimal or nonexistent.
DSR controls the vehicle’s speed when it is acti-
vated and the transmission is in position D,R or
N. You can drive at a higher or a lower speed
than that set on the on-board computer at any
time by accelerating or braking.
Important safety notes
GWARNING
If the speed driven and the set speed deviate and you activate DSR on a slippery road sur-
face, the wheels may lose traction. There is an
increased danger of skidding and accidents.
Before switching DSR on, please take into
consideration the road surface and the differ- ence between driving speed and the set
speed.
If you fail to adapt your driving style, DSR can
neither reduce the risk of accident nor override the laws of physics. DSR cannot take account of
road, weather and traffic conditions. DSR is only
an aid. You are responsible for the distance to
180Driving system s
Driving an d parking
Page 183 of 382

the vehicle in front, for vehicle speed, for brak-
ing in good time and for staying in your lane.
You are always responsible for keeping control
of the vehicle and for assessing whether the
downhill gradient can be managed. DSR may not
always be able to keep to the set speed, depend-
ing on road surface and tire conditions. Select a
set speed suitable for the prevailing conditions
and when necessary, apply the brakes manually.
Activating DSR
XPress button:.
Indicator lamp ;lights up.
The à DSR symbol appears in the multi-
function display with the Enabled
message.
You can only activate DSR when driving at
speeds below 25 mph (40 km/h).
If the current vehicle speed is too high, the Ã
DSR symbol appears in the multifunction display
with the Max. speed 25 mph
message (Can-
ada: 40 km/h).
You cannot activate DSR if the SportorSport
Plus drive program is activated. The ÃDSR
symbol and the Not
indriveprogramSPORTmessage then appears in the multifunction dis-
play.
If you have activated DSR and you change the
drive program, DSR is deactivated.
Deactivating DSR
XPress button:.
Indicator lamp ;goes out.
The à DSR symbol appears in the multi-
function display with the Off
message.
DSR switches off automatically if you drive
faster than 28 mph (Canada: 45 km/h). The
à DSR symbol appears in the multifunction
display with the Off
message. The status indi-
cator in the multifunction display goes out. You
also hear a warning. On vehicles with the Off-
road Engineering package, if you select a differ-
ent onroad/offroad program, DSR is also deac-
tivated.
Changing the set speed
XTo increase or reduce the set speed in
1 mph increments (Canada: 1 km/hi ncre-
ments): briefly press the cruise control lever
up : for a higher set speed or down ;for a
lower set speed.
The set speed appears in the multifunction
display with the ÃDSR symbol.
When DSR is activated, you can change the set
speed to a value between 1 mph and 11 mph
(Canada: between 2 km/h and 18 km/h).

iThe DSR set speed is always changed in
1 mph increments (Canada: 1 km/h incre-
ments). This is regardless of whether you
press the cruise control lever to or beyond the
pressure point.
AIRMATIC package
General notes
AIRMATIC is an air suspension with variable
damping for improved driving comfort. Level
control ensures the best possible suspension
and constant ground clearance, even with a
laden vehicle. When you drive fast, the vehicle is
lowered automatically to improve driving safety
and to reduce fuel consumption. There is also
the option to manually adjust the vehicle level.
AIRMATIC consists of:
Rlevel settings
Rlevel control and
RADS PLUS (Adaptive Damping System)
All vehicles (except Mercedes-AMG vehi-
cles): your vehicle may also be equipped with
the ACTIVE CURVE SYSTEM (
Ypage 183).
Mercedes-AMG vehicles: your vehicle is equip-
ped with the ACTIVE CURVE SYSTEM.
(
Ypage 183).
Observe the notes on driving with a trailer
(
Ypage 212).
The vehicle level can be set using the DYNAMIC
SELECT controller (
Ypage 142) or the level but-
ton (Ypage 183). The setting always corre-
sponds to the last selected function.
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.
If you unlock the vehicle or open a door, the
vehicle begins to compensate for load discrep-
ancies while still parked. However, for signifi- cant level changes, such as after the vehicle has
been stationary for a long period, the engine
must be on. For safety reasons, the vehicle is
only lowered when the doors are closed. Low-
ering is interrupted if a door is opened, and it
continues once the door has been closed.
ADS PLUS (Adaptive Damping System)
General notes
ADS PLUS automatically controls the calibration
of the dampers. The damping characteristics
adapt to the current operating and driving sit-
uation.
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
Rthe vehicle level setting
Selecting Comfort mode
In the Comfort drive program, the driving char-
acteristics of your vehicle are more comforta-
ble. Therefore, select this mode if you favor a
more comfortable driving style. Also select the
Comfort drive program when driving fast on
straight roads, e.g. on straight stretches of high-
way.
XSelect the Comfortdrive program using
DYNAMIC SELECT controller :.
The vehicle is adjusted to normal level.
All vehicles (except Mercedes-AMG vehi-
cles): in theComfort drive program, the vehicle
is lowered by 0.6 in (15 mm) if you:
Rdrive at speeds above 78 mph (125 km/h).
The vehicle is raised again if you:
Rdrive at speeds below 50 mph (80 km/h).
