nance requirements as well as technical events
and malfunctions.
This information generally documents the con-
dition of a component, a module, a system or the
surroundings, such as:
R Operating states of system components (e.g.
fill levels, battery status, tire pressure)
R Status messages concerning the vehicle or its
individual components (e.g. wheel rpm/
speed, deceleration, lateral acceleration, indi- cation of whether seat belts are fastened)
R Malfunctions and defects in important system
components (e.g. lights, brakes)
R Information about events leading to vehicle
damage
R System responses in special driving situa-
tions (e.g. air bag deployment, intervention of
stability control systems)
R Ambient conditions (e.g. temperature, rain
sensor)
In addition to performing the actual control unit
function, this data is used by manufacturers to
detect and rectify malfunctions and to optimize vehicle functions. Most of this data is volatile
and processed only in the vehicle itself. Only a
small part of the data is stored in event or mal-
function memories.
When you use services, the technical data from
the vehicle can be read out by service network
employees (e.g. workshops, manufacturers) or
third parties (e.g. breakdown services). Services
can include repair services, maintenance pro-
cesses, warranty cases and quality assurance
measures. The data are read out via the con-
nection for the diagnostics connection in the
vehicle, which is required by law. The relevant
offices in the service network or third parties
collect, process and use the data. This data
documents the vehicle's technical states, is
used to help in finding malfunctions and improv-
ing quality and is sent to the manufacturer
where necessary. In addition, the manufacturer is subject to product liability. The manufacturerneeds technical data from vehicles for this pur-
pose.
Malfunction memories in the vehicle can be
reset by a service center during repair or service
work.
You can incorporate data into the vehicle's com- fort and infotainment functions yourself as part
of the selected equipment. These include, for example:
R Multimedia data such as music, films or pho-
tos for playback in an integrated multimedia
system
R Address book data for use in conjunction with
an integrated hands-free system or an inte-
grated navigation system
R Navigation destinations that have been
entered
R Data about using Internet services
This data can be saved locally in the vehicle or
located on a device that you have connected to
the vehicle (e.g. smartphone, USB memory stick or MP3 player). If this data is saved in the vehi-
cle, you can delete it at any time. This data is
sent to third parties only at your request, par-
ticularly when you use online services in accord- ance with the settings that you have selected.
You can save and change comfort settings/
customizations in the vehicle at any time.
Depending on the equipment in question, these can include:
R Seat and steering wheel position settings
R Suspension and climate control settings
R Custom settings such as interior lighting
If your vehicle is equipped appropriately, you
can connect your smartphone or another mobile end device to the vehicle. You can control this by
means of the control elements integrated in the vehicle. The smartphone's picture and sound
can be output via the multimedia system. Spe-
cific items of information are also sent to your
smartphone.
Depending on the type of integration, this can
include:
R General vehicle information
R Position data
This allows the use of selected smartphone
apps, such as navigation or music player apps.
There is no additional interaction between the
smartphone and the vehicle, particularly active
access to vehicle data. The type of additional
data processing is determined by the provider of the app being used. Whether you can configure
settings for it and, if so, which ones, depends on
the app and your smartphone's operating sys-
tem. Data stored in the vehicle

tem)
All vehicles (except Mercedes-AMG vehi-
cles): your vehicle may also be equipped with
the ACTIVE CURVE SYSTEM (Y page 186).
Mercedes-AMG vehicles: your vehicle is equip-
ped with the ACTIVE CURVE SYSTEM
(Y page 186).
Observe the notes on driving with a trailer
(Y page 222).
The vehicle level can be set using the DYNAMIC
SELECT controller (Y page 147) or the level but-
ton (Y page 187). The setting always corre-
sponds to the last selected function.
Important safety notes G
WARNING
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 and ADS PLUS (Adaptive Damping
System) General notes
The Adaptive Damping System automatically
controls the calibration of the dampers. The
damping characteristics adapt to the current
operating and driving situation.
The damping is tuned individually to each wheel
and depends on:
R your driving style, e.g. sporty
R the road surface conditions
R the drive program selected
R the 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. Driving systems

Important safety notes Parking Assist PARKTRONIC is an electronic
parking aid with ultrasound. It monitors the area
around your vehicle using six sensors in the
front bumper and six sensors in the rear
bumper. Parking Assist PARKTRONIC visually
and audibly indicates the distance between your
vehicle and an object.
Parking Assist PARKTRONIC is only an aid. It is
not a replacement for your attention to your
immediate surroundings. You are always
responsible for safe maneuvering, parking and
exiting a parking space. Make sure that there
are no persons, animals or objects in the maneu- vering area while maneuvering and parking in/
leaving parking spaces.
! 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.
! Fold in the ball coupling if the trailer tow
hitch is not required. PARKTRONIC measures
the minimum detection range to an obstacle
from the bumper, not the ball coupling.
Parking Assist PARKTRONIC is deactivated for
the rear area when you establish an electrical
connection between your vehicle and a trailer.
Parking Assist PARKTRONIC is activated auto-
matically when you:
R switch on the ignition
R shift the transmission to position 005B,005Eor
005C
R release the electric parking brake.
Parking Assist PARKTRONIC is deactivated at
speeds above 11 mph (18 km/h). It is reactiva- ted at lower speeds. Driving systems
189Driving and parking Z

To avoid hazardous situations:
R never install snow chains to the front
wheels
R always install snow chains in pairs to the
rear wheels.
! Check the snow chains for damage before
mounting them. Damaged or worn snow
chains may snap and damage the following
components:
R wheel
R wheel housing
R wheel suspension
For this reason, you must use only snow
chains that are free of defects. Observe the
manufacturer's mounting instructions.
! You must drive at raised vehicle level (height
1) if snow chains have been installed. The
vehicle may otherwise be damaged.
! Vehicles with ADS (Adaptive Damping
System): do not use the sport mode when
driving with snow chains mounted. The vehi-
cle may otherwise be damaged.
For safety reasons, Mercedes-Benz recom-
mends that you only use snow chains that have been specially approved for your vehicle by
Mercedes-Benz, or are of a corresponding
standard of quality. For more information,
please contact a qualified specialist workshop.
Install the snow chains on all driven wheels for
maximum tractive power and driving stability. If
you own snow chains for two driven wheels only, install the snow chains to the wheels on the rear
axle. The vehicle then remains more stable
under braking.
If you intend to mount snow chains, please bear
the following points in mind:
R Snow chains may not be mounted on all
wheel/tire combinations. Permissible
wheel/tire combinations (Y page 377).
R Only use snow chains when driving on roads
completely covered by snow. Remove the
snow chains as soon as possible when you
come to a road that is not snow-covered.
R Local regulations may restrict the use of snow
chains. Observe the appropriate regulations if
you wish to mount snow chains. R
Do not exceed the maximum permissible
speed of 30 mph (50 km/h).
R When snow chains are installed, never use
Active Parking Assist (Y page 192) or the
Parking Package with rear view camera.
You may wish to deactivate ESP ®
(Y page 71)
when pulling away with snow chains mounted.
You can thereby allow the wheels to spin in a
controlled manner, achieving an increased driv-
ing force (cutting action).
Information about driving with an emergency
spare wheel (Y page 378). Tire pressure
Tire pressure specifications
Important safety notes G
WARNING
Underinflated or overinflated tires pose the
following risks:
R the tires may burst, especially as the load
and vehicle speed increase.
R the tires may wear excessively and/or
unevenly, which may greatly impair tire
traction.
R the driving characteristics, as well as steer-
ing and braking, may be greatly impaired.
There is a risk of an accident.
Follow recommended tire inflation pressures
and check the pressure of all the tires includ-
ing the spare wheel:
R monthly, at least
R if the load changes
R before beginning a long journey
R under different operating conditions, e.g.
off-road driving
If necessary, correct the tire pressure.
Details on tire pressure can be found at the fol-
lowing positions in the vehicle:
R Tire and Loading Information placard on the
B-pillar on the driver's side
R Table for tire pressure on the inside of the fuel

355Wheels and tires Z

PSI (pounds per square inch)
A standard unit of measure for tire pressure.
Aspect ratio
Relationship between tire height and tire width
in percent.
Tire pressure
This is pressure inside the tire applying an out-
ward force to each square inch of the tire's sur-
face. The tire pressure is specified in pounds per
square inch (psi), in kilopascal (kPa) or in bar.
The tire pressure should only be corrected when
the tires are cold.
Cold tire pressure
The tires are cold:
R if the vehicle has been parked with the tires
out of direct sunlight for at least three hours
and
R if the vehicle has not been driven further than
1 mile (1.6 km)
Tread
The part of the tire that comes into contact with
the road.
BeadThe tire bead ensures that the tire sits securely
on the wheel. There are several steel wires in the
bead to prevent the tire from coming loose from the wheel rim.
Sidewall The part of the tire between the tread and the
bead.
Weight of optional extras The combined weight of those optional extras
that weigh more than the replaced standard
parts and more than 2.3 kg (5 lbs). These
optional extras, such as high-performance
brakes, level control, a roof rack or a high-per-
formance battery, are not included in the curb
weight and the weight of the accessories.
TIN (Tire Identification Number) This is a unique identifier which can be used by
a tire manufacturer to identify tires, for example for a product recall, and thus identify the pur-
chasers. The TIN is made up of the manufactur-
er's identity code, tire size, tire type code and
the manufacturing date. Load bearing index
The load bearing index (also load index) is a code that contains the maximum load bearing capa-
city of a tire.
Traction
Traction is the result of friction between the tires and the road surface.
TWR (Tongue Weight Rating)
The TWR specifies the maximum permissible
weight that the ball coupling of the trailer tow
hitch can support.
Treadwear indicators Narrow bars (tread wear bars) that are distrib-
uted over the tire tread. If the tire tread is level
with the bars, the wear limit of 00CDin (1.6 mm)
has been reached.
Occupant distribution
The distribution of occupants in a vehicle at their designated seating positions.
Total load limit Nominal load and luggage load plus 68 kg
(150 lbs) multiplied by the number of seats in
the vehicle. Changing a wheel
Flat tire
The "Breakdown assistance" section
(Y page 335) contains information and notes on
how to deal with a flat tire. Information on driv-
ing with MOExtended tires in the event of a flat
tire can be found under "MOExtended tires (tires with run-flat characteristics" (Y page 336).
