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.
For further information on deactivating
DISTRONIC PLUS ( Y
page 191).
If DISTRONIC PLUS 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.
i After a time, the electric parking brake
secures the vehicle and relieves the service
brake.
i Depending 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 DISTRONIC PLUS is activated, the trans-
mission is shifted automatically to position P if: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-
matical ly switched off by the ECO start/stop
functi on.
The electric parking brake secures the vehicle
automatically if DISTRONIC PLUS is activated
when the vehicle is stationary and: R
a system malfunction occurs. R
the power supply is not sufficient.
If a malfunction occurs, the transmission may
also shift into position P automatically.
Setting a speed X
Press the cruise control lever up C for a
higher speed or down D for a lower speed.X
To adjust the set speed in 1 mph incre-
ments (1 km/h increments): briefly press the cruise control lever up C or down D to
the pressure point.
Every time the cruise control lever is pressed
up C or down D the last speed stored is
increased or reduced. X
To adjust the set speed in 5 mph incre-
ments (1 0 km/h increments): briefly press
the cruise control lever up C or down D to
the pressure point.
Every time the cruise control lever is pressed
up C or down D , the last speed stored is
increased or reduced.
i If you accelerate to overtake, DISTRONIC
PLUS adjusts the vehicle's speed to the last
speed stored after you have finished overtak-
ing.
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 keeps to the vehicle in front,
dependent on vehicle speed. You can see this
distance in the multifunction display
( Y
page 191).
i Make sure that you maintain the minimum
distance to the vehicle in front as required by
law. Adjust the distance to the vehicle in front
if necessary.

Tips for driving with DISTRONIC PLUS
General notes Pay particular attention in the following traffic
situations: R
Cornering, entering and exiting a bend: the
ability of DISTRONIC PLUS to detect vehicles
when cornering is limited. Your vehicle may
brake unexpectedly or late. R
Driving on a different line: DISTRONIC PLUS
may not detect vehicles which are not driving
in the middle of their lane. The distance to the
vehicle in front will be too short. R
Other vehicles changing lane: DISTRONIC
PLUS has not detected the vehicle cutting in
yet. The distance to this vehicle will be too
short. R
Narrow vehicles: DISTRONIC PLUS does not
detect the vehicle in front on the edge of the
road because of its narrow width. The dis-
tance to the vehicle in front will be too short. R
Obstacles 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. R
Crossing vehicles: DISTRONIC PLUS may mis-
takenly detect vehicles that are crossing your
lane. Activating DISTRONIC PLUS at traffic
lights with crossing traffic, for example, could
cause your vehicle to pull away unintention-
ally.
In such situations, brake if necessary.
DISTRONIC PLUS is then deactivated.
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 multifunction camera C , at the top of
the windshield.
In a speed range from 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 clear lane markings
(left and right), only focusing on the vehicle in
front if clear lane markings are not present.
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 nor192

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 responsible
for the distance to the vehicle in front, for vehi-
cle speed, for braking in good time and for stay-
ing in your lane.
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 be
corrected 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 system may be impaired or may not function
if: R
there is poor visibility, e.g. due to insufficient
illumination of the road, or due to snow, rain,
fog or spray R
there is glare, e.g. from oncoming traffic, the
sun or reflections (e.g. when the road surface
is wet) R
the windshield is dirty, fogged up, damaged or
covered, for instance by a sticker, in the vicin-
ity of the camera R
there are no, several or unclear lane markings
for a lane, e.g. in areas with road construction
work R
the lane markings are worn away, dark or cov-
ered up, e.g. by dirt or snow R
the distance to the vehicle in front is too small
and the lane markings thus cannot be detec-
ted R
the lane markings change quickly, e.g. lanes
branch off, cross one another or merge R
the road is narrow and winding R
there are strong shadows cast on the road The syst em is switched to passive and no longer
assist s you by performing steering interventions
if: R
you actively change lane R
you switch on the turn signal R
take your hands off the steering wheel or do
not steer for a prolonged period of time
i Steering 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: R
on very sharp corners R
when a loss of tire pressure or a defective tire
has been detected and displayed
Pay attention also to the important safety notes
for DISTRONIC PLUS ( Y
page 187).
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.

AIRMATIC
General notes AIRMATIC is an air suspension with variable
damping for improved driving comfort. All-round
level control ensures the best possible suspen-
sion 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 level setting, level control
and the Adaptive Damping System ADS.
Important safety notes

Active Parking Assist
General notes Active Parking Assist is an electronic parking aid
with ultrasound. It measures the road on both
sides of the vehicle. A parking symbol indicates
a suitable parking space. Active steering inter-
vention and brake application can assist you
during parking and when exiting a parking
space. You may also use PARKTRONIC
( Y
page 199).
Important safety notes Active Parking Assist is merely an aid. It is not a
replacement for your attention to your immedi-
ate surroundings. You are always responsible
for safe maneuvering, parking and exiting a
parking space. Make sure that no persons, ani-
mals or objects are in the maneuvering range.
When PARKTRONIC is switched off, Active Park-
ing Assist is also unavailable.
G WARNING
While parking or pulling out of a parking
space, the vehicle swings out and can drive
onto areas of the oncoming lane. This could result in a collision with another road user.
There is a risk of an accident.
Pay attention to other road users. Stop the
vehicle if necessary or cancel the Active Park-
ing Assist parking procedure.
! If unavoidable, you should drive over obsta-
cles such as curbs slowly and not at a sharp
angle. Otherwise, you may damage the
wheels or tires.
Active Parking Assist may also display spaces
not suitable for parking, e.g.: R
where parking or stopping is prohibited R
in front of driveways or entrances and exits R
on unsuitable surfaces
Parking tips: R
On narrow roads, drive as close to the parking
space as possible. R
Parking spaces that are littered or overgrown
might be identified or measured incorrectly. R
Parking spaces that are partially occupied by
trailer drawbars might not be identified as
such or be measured incorrectly. R
Snowfall or heavy rain may lead to a parking
space being measured inaccurately.202
