Distance Pilot DISTRONIC
General notes
Distance Pilot DISTRONIC regulates the speed
and automatically helps you maintain the dis-
tance to the vehicle detected in front. Vehicles
are detected with the aid of the radar sensor
system. Distance Pilot DISTRONIC brakes auto-
matically so that the set speed is not exceeded. Change into a lower gear in good time on long
and steep downhill gradients. This is especially
important if the vehicle is laden. By doing so, you
will make use of the braking effect of the engine.
This relieves the load on the brake system and
prevents the brakes from overheating and wear-
ing too quickly.
If Distance Pilot DISTRONIC detects that there is a risk of a collision, you will be warned visually
and acoustically. Without your intervention, Dis-
tance Pilot DISTRONIC cannot prevent a colli-
sion. An intermittent warning tone will then
sound and the distance warning lamp will light
up in the instrument cluster. Brake immediately in order to increase the distance to the vehicle in
front or take evasive action provided it is safe to
do so.
Distance Pilot DISTRONIC operates in the range
between 0 mph (0 km/h) and 120 mph
(200 km/h).
Do not use Distance Pilot DISTRONIC whi
le driv-
ing on roads with steep gradients.
Since Distance Pilot DISTRONIC transmits radar
waves, it can resemble the radar detectors of
the responsible authorities. You can refer to the
relevant chapter in the Operator's Manual if
questions are asked about this.

Important safety notes
GWARNING
Distance Pilot DISTRONIC does not react to:
Rpeople or animals
Rstationary objects on the road, e.g. stopped
or parked vehicles
Roncoming vehicles and crossing traffic
As a result, Distance Pilot DISTRONIC may
neither give warnings nor intervene in such
situations. There is a risk of an accident.
Always pay careful attention to the traffic sit- uation and be ready to brake.
GWARNING
Distance Pilot DISTRONIC cannot always
clearly identify other road users and complex
traffic situations.
In such cases, Distance Pilot DISTRONIC may:
Rgive an unnecessary warning and then
brake the vehicle
Rneither give a warning nor intervene
Raccelerate or brake unexpectedly
There is a risk of an accident.
Continue to drive carefully and be ready to
brake, especially if Distance Pilot DISTRONIC
warns you.
GWARNING
Distance Pilot DISTRONIC brakes your vehicle with up to 50% of the maximum possible
deceleration. If this deceleration is not suffi-
cient, Distance Pilot DISTRONIC alerts you
with a visual and acoustic warning. There is a
risk of an accident.
Apply the brakes yourself in these situations
and try to take evasive action.
!When Distance Pilot DISTRONIC or the
HOLD function are activated, the vehicle
brakes automatically in certain situations. To avoid damage to the vehicle, deactivate
these systems in the following or similar sit-
uations:
Rwhen towing the vehicle
Rin the car wash
Distance Pilot DISTRONIC can neither reduce
the risk of an accident if you fail to adapt your
driving style nor override the laws of physics.
Distance Pilot DISTRONIC cannot take into
account road, weather or traffic conditions. Dis-
tance Pilot DISTRONIC is only an aid. You are
responsible for maintaining a safe distance to
the vehicle in front, for vehicle speed, for brak-
ing in good time and for staying in lane.
Do not use Distance Pilot DISTRONIC:
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
Rin poor visibility, e.g. due to fog, heavy rain or
snow
Distance Pilot DISTRONIC may not detect nar-
row 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 exam-
ple in parking garages
If Distance Pilot DISTRONIC no longer detects a
vehicle in front, it may unexpectedly accelerate
to the speed stored.
This speed may:
Rbe too high if you are driving in a turning lane
or an exit lane
Rbe so high in the right lane that you pass vehi- cles driving on the left (in countries where
they drive on the right)
Rbe so high in the left lane that you pass vehi-
cles driving on the right (in countries where
they drive on the left)
If there is a change of drivers, advise the new
driver of the speed stored.

XRemove your foot from the accelerator pedal.
The vehicle adapts its speed to that of the
vehicle in front, but only up to the desired
stored speed.
If you do not fully release the accelerator
pedal, the Distance
PilotSuspendedmes-
sage appears on the multifunction display.
The set distance to a slower-moving vehicle in
front will then not be maintained. You will be
driving at the speed you determine by the
position of the accelerator pedal.
You can also activate Distance Pilot DISTRONIC
when stationary. The lowest speed that can be
set is 20 mph (30 km/h).
XBriefly pull the cruise control lever towards
you ?or push it up :or down ;.

Activating at the current speed/last
stored speed
GWARNING
If you call up the stored speed and it differs
from the current speed, the vehicle acceler-
ates or decelerates. If you do not know the
stored speed, the vehicle could accelerate or brake unexpectedly. There is a risk of an acci-
dent.
Pay attention to the road and traffic condi-
tions before calling up the stored speed. If you
do not know the stored speed, store the
desired speed again.
XBriefly pull the cruise control lever towards
you ?.
XRemove your foot from the accelerator pedal.
The first time Distance Pilot DISTRONIC is
activated, it stores the current speed or reg-
ulates the speed of the vehicle to the previ-
ously stored speed.

with the curb or other road boundaries. Be par-
ticularly aware of other road users, e.g. cyclists,
that are directly next to your vehicle.
Obstacles such as traffic markers on a con-
struction site that are on the lane or projecting
out into the lane are not detected.
An inappropriate steering intervention, e.g. afterintentionally driving over a lane marking, can be
corrected at any time if you steer slightly in theopposite direction.
DISTRONIC PLUS with Steering Pilot cannot
continuously keep your vehicle in lane. In some
cases, 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:
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 reflection from other vehicles (e.g. if
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 or several unclear lane markings
for one lane, e.g. roadworks
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 short
and thus the lane markings 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 highly variable shade conditions on the roadway
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
Ryou take your hands off the steering wheel or
do not steer for a prolonged period of time
After you have finished changing lanes, Steering
Pilot is automatically active once more. Steering Pilot cannot provide assistance:
Ron very sharp corners
Rwhen a loss of tire pressure or a defective tire
has been detected and displayed
Pay attention also to the important safety notes
on Distance Pilot DISTRONIC (
Ypage 172).
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, a warning tone also
sounds to remind you to take control of the
vehicle after five seconds at the latest. Steering

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 ADS PLUS (Adaptive Damping System with
continuous damping adjustment).
The vehicle level can be set using the DYNAMIC
SELECT switch (
Ypage 144) or the level button
(Ypage 182). The setting always corresponds
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.
iIf one of the doors is open, the vehicle is not
lowered.

4MATIC (permanent four-wheel drive)
4MATIC ensures permanent drive for all four
wheels. Together with ESP®, it improves the
traction of your vehicle whenever a drive wheel
spins due to insufficient grip.
If you fail to adapt your driving style or if you are inattentive, 4MATIC can neither reduce the risk
of an accident nor override the laws of physics.
4MATIC does not take into account
Rthe road and weather conditions
Rthe traffic situation
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.
!Never tow the vehicle with one axle raised.
This may damage the transfer case. 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.
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.
Parking Pilot
General notes
Parking Pilot is an electronic parking aid with
ultrasound. It measures the road on both sides
of the vehicle. A parking symbol indicates a suit-
able parking space. Active steering intervention
and brake application can assist you during
parking and when exiting a parking space. You can also still use Parking Assist PARKTRONIC
(
Ypage 188).
Important safety notes
Parking Pilot is only an aid. It is not a replace-
ment for your attention to your immediate sur-
roundings. You are always responsible for safe
maneuvering, parking and exiting a parking
space. Make sure that no persons, animals or
objects are in the maneuvering range.
When Parking Assist PARKTRONIC is deactiva-
ted, Parking Pilot is also unavailable.
GWARNING
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 Parking Pilot
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.
Parking Pilot may also display spaces not suita-
ble for parking, e.g.:
Rwhere parking or stopping is prohibited
Rin front of driveways or entrances and exits
Ron unsuitable surfaces
Parking tips:
ROn narrow roads, drive as close to the parking
space as possible.
RParking spaces that are littered or overgrown
might be identified or measured incorrectly.
RParking spaces that are partially occupied by
trailer drawbars might not be identified as
such or be measured incorrectly.
RSnowfall or heavy rain may lead to a parking
space being measured inaccurately.
RPay attention to the warning messages of
Parking Assist PARKTRONIC during the park-
ing procedure (
Ypage 189).
RYou can intervene in the steering procedure
to correct it at any time. Parking Pilot is then
canceled.

Driving and parking

RWhen transporting a load that protrudes fromyour vehicle, you should not use Parking Pilot
RNever use Parking Pilot when snow chains are
installed.
RAlways pay attention to the specified tire
pressure for your vehicle. This has a direct
influence on the parking characteristics of the
vehicle.
Use Parking Pilot for parking spaces that are:
Rparallel or at right angles to the direction of
travel
Ron straight roads, not bends
Ron the same level as the road, e.g. not on the
pavement
Detecting parking spaces
Objects located above the detection range of
Parking Pilot will not be detected when the park-
ing space is measured. These are not taken into
account when the parking procedure is calcula- ted, e.g. overhanging loads, tail sections or load-
ing ramps of trucks.
GWARNING
If there are objects above the detection range:
RParking Pilot may steer in too early
Rthe vehicle may not stop in front of these
objects
You may cause a collision as a result. There is
a risk of an accident.
If objects are located above the detection
range, stop and deactivate Parking Pilot.
For further information on the detection range
(
Ypage 188).
Parking Pilot does not assist you parking in
spaces at a right angle to the direction of travel
if:
Rtwo parking spaces are located directly next
to one another
Rthe parking space is directly next to a low
obstacle such as a low curb
Ryou forward-park Parking Pilot does not assist you parking in
spaces parallel with or at a right angle to the
direction of travel if:
Rthe parking space is on a curb
Rthe system reads the parking space as being
blocked, for example by foliage or grass pav-
ing blocks
Rthe area is too small for the vehicle to maneu-
ver into
Rthe parking space is bordered by an obstacle,
e.g. a tree, a post or a trailer
:Detected parking space on the left
;Parking symbol
=Detected parking space on the right
Parking Pilot is activated automatically when
driving forward. The system is operational at
speeds of up to approximately 22 mph
(35 km/h). While in operation, the system inde-
pendently locates and measures parking spaces on both sides of the vehicle.
Parking Pilot will only detect parking spaces
which are:
Rparallel or at right angles to the direction of
travel
Rthat are parallel to the direction of travel and
at least 59 in (1.5 m) 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 Parking Pilot PARKTRONIC cannot
measure the depth of parking spaces if they
are at right angles to the direction of travel.
You will need to judge whether your vehicle
will fit into the parking space.
