Notes on breaking-in a new vehicle
Important safety notes The sensor system of some driving and driving
safety systems adjusts automatically while a
certain distance is being driven after the vehicle
has been delivered or after repairs. Full system
effectiveness is not reached until the end of this
teach-in procedure.
New and replaced brake pads and discs only
reach their optimum braking effect after several
hundred kilometers of driving. Compensate for
this by applying greater force to the brake pedal.
The first 1000 miles (1500 km) The more you look after the engine when it is
new, the more satisfied you will be with its per-
formance in the future. R
You should therefore drive at varying vehicle
and engine speeds for the first 1000 miles
(1500 km). R
Avoid heavy loads, e.g. driving at full throttle,
during this period. R
Change gear in good time, before the tach-
ometer needle is

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 Cruise control is not deactivated if you
depress the accelerator pedal. For example, if
you accelerate briefly to overtake, cruise con-
trol adjusts the vehicle's speed to the last
speed stored after you have finished overtak-
ing.
Deactivating cruise control
There are several ways to deactivate cruise con-
trol: X
Briefly press the cruise control lever for-
wards C .
or X
Brake.
Cruise control is automatically deactivated if: R
you depress the parking brake R
you are driving at less than 20 mph (30 km/h) R
ESP ®
intervenes or you deactivate ESP ®
R
you 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 Off message in the multifunction display
for approximately five seconds.
i When you switch off the engine, the last
speed stored is cleared. DISTRONIC PLUS
General notes DISTRONIC PLUS regulates the speed and auto-
matically helps you maintain the distance to the
vehicle detected in front. Vehicles are detected
with the aid of the radar sensor system.
DISTRONIC PLUS brakes automatically 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 DISTRONIC PLUS detects that there is a risk of
a collision, you will be warned visually and
acoustically. DISTRONIC PLUS cannot prevent a
collision without your intervention. An intermit-
tent warning tone will then sound and the dis-
tance warning lamp will light up in the instru-
ment 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.
For DISTRONIC PLUS to assist you, the radar
sensor system must be operational.
DISTRONIC PLUS operates in range between
0 mph (0 km/h) and 120 mph (200 km/h) .
Do not use DISTRONIC PLUS while driving on
roads with steep gradients.
As DISTRONIC PLUS transmits radar waves, it
can resemble the radar detectors of the respon-
sible authorities. You can refer to the relevant
chapter in the Operator's Manual if questions
are asked about this.

Important safety notes
G WARNING
DISTRONIC PLUS does not react to: R
people or animals R
stationary obstacles on the road, e.g. stop-
ped or parked vehicles R
oncoming and crossing traffic
As a result, DISTRONIC PLUS 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.
G WARNING
DISTRONIC PLUS cannot always clearly iden-
tify other road users and complex traffic sit-
uations.
In such cases, DISTRONIC PLUS may: R
give an unnecessary warning and then
brake the vehicle R
neither give a warning nor intervene R
accelerate or brake unexpectedly
There is a risk of an accident.
Continue to drive carefully and be ready to
brake, in particular when warned to do so by
DISTRONIC PLUS.
G WARNING
DISTRONIC PLUS brakes your vehicle 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 automatically in
certain situations.
To prevent damage to the vehicle, deactivate
DISTRONIC PLUS and the HOLD function in
the following or other similar situations: R
when towing the vehicle R
in 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: R
in road and traffic conditions which do not
allow you to maintain a constant speed, e.g. in
heavy traffic or on winding roads R
on slippery road surfaces. Braking or accel-
erating could cause the drive wheels to lose
traction and the vehicle could then skid R
when there is poor visibility, e.g. due to fog,
heavy rain or snow
DISTRONIC PLUS may not detect narrow vehi-
cles driving in front, e.g. motorcycles, or vehi-
cles driving on a different line.
In particular, the detection of obstacles can be
impaired if: R
there is dirt on the sensors or anything else
covering the sensors R
there is snow or heavy rain R
there is interference by other radar sources R
there are strong radar reflections, for exam-
ple, in parking garages
If DISTRONIC PLUS no longer detects a vehicle
in front, DISTRONIC PLUS ma y unexpectedly
accelerate the vehicle to the stored speed.156

! 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.
i In 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.
4MATIC ensures that all four wheels are perma-
nently driven. Together with ESP ®
, it improves
the traction of your vehicle whenever a drive
wheel spins due to insufficient grip.
PARKTRONIC
Important safety notes PARKTRONIC is an electronic parking aid with
ultrasonic sensors. It monitors the area around
your vehicle using six sensors in the front
bumper and six sensors in the rear bumper.
PARKTRONIC indicates visually and audibly the
distance between your vehicle and an object.
PARKTRONIC 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. When maneuvering, parking or pulling
out of a parking space, make sure that there are
no persons, animals or objects in the area in
which you are maneuvering.
! When parking, pay particular attention to
objects above or below the sensors, such as
flower pots or trailer drawbars. PARKTRONIC
does not detect such objects when they are in
the immediate vicinity of the vehicle. You
could damage the vehicle or the objects.
The sensors may not detect snow and other
objects that absorb ultrasonic waves.
Ultrasonic sources such as an automatic car
wash, the compressed-air brakes on a truck
or a pneumatic drill could cause PARKTRONIC
to malfunction.
PARKTRONIC may not function correctly on
uneven terrain. PARKTRONIC is activated automatically when
you: R
switch on the ignition R
shift the transmission to position D , R or NR
release the parking brake
PARKTRONIC is deactivated at speeds above
11 mph (18 km/h). It is reactivated at lower
speeds.
Range of the sensors General notes PARKTRONIC does not take objects into con-
sideration that are: R
below the detection range, e.g. people, ani-
mals or objects. R
above the detection range, e.g. overhanging
loads, truck overhangs or loading ramps.
C
Sensors in the front bumper, left-hand side
(example)
The sensors must be free from dirt, ice or slush.
They can otherwise not function correctly. Clean
the sensors regularly, taking care not to scratch
or damage them ( Y

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. You may also use PARKTRONIC
( Y
page 170).
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 possibly indicate
parking spaces which are not suitable for park-
ing, for example: 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.Driving systems 173

must be observed.
Canceling the speed limit
The speed limit no longer applies C .
i The unit for the speed limit (km/h or mph)
depends on the country in which you are driv-
ing. It is generally neither shown on the traffic
sign nor on the instrument cluster but must be
taken into account when observing the max-
imum permitted speed.
Lane Tracking package
General notes The Lane Tracking package consists of Blind
Spot Assist ( Y
page 187) and Lane Keeping
Assist ( Y
page 189).
Blind Spot Assist
General notes Blind Spot Assist uses a radar sensor system to
monitor the areas on both sides of your vehicle.
It supports you from a speed of approximately
20 mph (30 km/h). A warning display in the
exterior mirrors draws your attention to vehicles
detected in the monitored area. If you then
switch on the corresponding turn signal to
change lanes, you will also receive an optical
and audible collision warning. Blind Spot Assist
uses sensors in the rear bumper for monitoring
purposes.
Important safety notes
G WARNING
Blind Spot Assist does not react to: R
vehicles overtaken too closely on the side,
placing them in the blind spot area R
vehicles which approach with a large speed
differential and overtake your vehicle As a result, Blind Spot Assist may not give
warnings in such situations. There is a risk of
an accident.
Always observe the traffic conditions care-
fully, and maintain a safe lateral distance.
Blind Spot Assist is only an aid. It may fail to
detect some vehicles and is no substitute for
attentive driving. Always ensure that there is
sufficient distance to the side for other road
users and obstacles.

Monitoring range of the sensors In particular, the detection of obstacles can be
impaired if: R
there is dirt on the sensors or anything else
covering the sensors R
there is poor visibility, e.g. due to fog, heavy
rain, snow or spray R
there are narrow vehicles, e.g. motorcycles or
bicycles R
the road has very wide lanes R
the road has narrow lanes R
you are not driving in the middle of the lane R
there are barriers or similar lane borders
Vehicles in the monitoring ra nge are then not
i ndicated.Driving systems 187
Driving and parking Z

Page 190 of 342

If the lanes are narrow, vehicles driving in the
lane beyond the lane next to your vehicle may be
indicated, especially if the vehicles are not driv-
ing in the middle of their lane. This may be the
case if there are vehicles driving at the inner
edge of their lanes.
Due to the nature of the system: R
warnings may be issued in error when driving
close to crash barriers or similar solid lane
borders. R
the warning is canceled when driving for an
extended period next to long vehicles, such as
trucks.
The two radar sensors for Blind Spot Assist are
integrated into the sides of the rear bumper.
Make sure that the bumper is free of dirt, ice or
slush in the vicinity of the sensors. The sensors
must not be covered, for example by cycle racks
or overhanging loads. Following a severe impact
or in the event of damage to the bumpers, have
the function of the sensors checked at a quali-
fied specialist workshop. Blind Spot Assist may
otherwise not work properly. Indicator and warning display
C
Indicator lamp (yellow)
Warning lamp (red)
Blind Spot Assist is not active at speeds below
approximately 20 mph (30 km/h). Vehicles in
the monitoring range are then not indicated.
When Blind Spot Assist is activated, indicator
lamp C in the exterior mirrors lights up yellow
at speeds of up to 20 mph (30 km/h). At speeds
above 20 mph (30 km/h), the indicator lamp
goes out and Blind Spot Assist is operational.
If a vehicle is detected within the blind spot
monitoring range at speeds above 20 mph
(30 km/h), warning lamp C on the correspond-
ing side lights up red. This warning is always
emitted when a vehicle enters the blind spot
monitoring range from behind or from the side.
When you overtake a vehicle, the warning only
occurs if the difference in speed is less than
7 mph (12 km/h).
The yellow indicator lamp goes out if reverse
gear is engaged. In this event, Blind Spot Assist
is no longer active.
The brightness of the indicator or warning lamps
is adjusted automatically according to the ambi-
ent light.
Collision warning
If a vehicle is detected in the monitoring range of
Blind Spot Assist and you switch on the corre-
sponding turn signal, a double warning tone
sounds. Red warning lamp C flashes. If the turn
signal remains on, detected vehicles are indica-
ted by the flashing of red warning lamp C .
There are no further warning tones.188

In order that you are warned only when neces-
sary and in good time if you cross the lane mark-
ing, the system recognizes certain conditions
and warns you accordingly.
The warning vibration occurs earlier if: R
you approach the outer lane marking on a
bend. R
the road has very wide lanes, e.g. a highway. R
the system recognizes solid lane markings.
The warning vibration occurs later if: R

Active Driving Assistance package
General notes
The Active Driving Assistance package consists
of DISTRONIC PLUS ( Y
page 155), Active Blind
Spot Assist ( Y
page 190) and Active Lane Keep-
ing Assist ( Y
page 193). Active Blind Spot Assist General notes Active Blind Spot Assist uses a radar sensor
system, pointed toward the rear of the vehicle,
to monitor the area to the sides of the vehicle
which the driver is unable to see. A warning dis-
play in the exterior mirrors draws your attention
to vehicles detected in the monitored area. If
you then switch on the corresponding turn sig-
nal to change lane, you will also receive an opti-
cal and audible warning. If a risk of lateral colli-
sion is detected, corrective braking may help
you avoid a collision. Before a course-correcting
brake application, Active Blind Spot Assist eval-
uates the space in the direction of travel and at
the sides of the vehicle. For this, Active Blind
Spot Assist uses the forward-facing radar sen-
sors.
Active Blind Spot Assist supports you from a
speed of approximately 20 mph (30 km/h).
Important safety notes Active Blind Spot Assist is only an aid and is not
a substitute for attentive driving.
G WARNING
Active Blind Spot Assist does not react to: R
vehicles overtaken too closely on the side,
placing them in the blind spot area R
vehicles which approach with a large speed
differential and overtake your vehicle
As a result, Active Blind Spot Assist may nei-
ther give warnings nor intervene in such sit-
uations. There is a risk of an accident.
Always observe the traffic conditions care-
fully, and maintain a safe lateral distance.
