Mercedes-Benz recommends that you use a
Mercedes-Benz Service Centre. Vehicle registration
Mercedes-Benz may ask its Service Centres
to carry out technical inspections on certain
vehicles. The quality or safety of the vehicle is
improved as a result of the inspection.
Mercedes-Benz can only inform you about
vehicle checks if it has your registration data.
It is possible that your vehicle has not yet
been registered in your name in the following
cases:
R if your vehicle was not purchased at an
authorised specialist dealer.
R if your vehicle has not yet been examined at
a Mercedes-Benz Service Centre.
It is advisable to register your vehicle with a
Mercedes-Benz Service Centre.
Inform Mercedes-Benz as soon as possible
about any change in address or vehicle own-
ership. You can do this at a Mercedes-Benz
Service Centre, for example. Correct use
If you remove any warning stickers, you or
others could fail to recognise certain dangers. Leave warning stickers in position.
Observe the following information when driv-ing your vehicle:
R the safety notes in this manual
R the technical data in this manual
R traffic rules and regulations
R laws and safety standards pertaining to
motor vehicles Implied warranty
! Follow the instructions in this manual
about the proper operation of your vehicle as well as about possible vehicle damage.
Damage to your vehicle that arises from
culpable contraventions against these
instructions are not covered either by
Mercedes-Benz implied warranty or by the
New or Used-Vehicle Warranty.
Data stored in the vehicle
A wide range of electronic components in
your vehicle contain data memories.
These data memories temporarily or perma-
nently store technical information about:
R the vehicle's operating state
R events
R faults
In general, this technical information docu-
ments the state of a component, a module, a
system or the surroundings.
These include, for example:
R operating conditions of system compo-
nents, e.g. fluid levels
R the vehicle's status messages and those of
its individual components, e.g. number of
wheel revolutions/speed, deceleration in
movement, lateral acceleration, accelera-
tor pedal position
R malfunctions and defects in important sys-
tem components, e.g. lights, brakes
R vehicle reactions and operating conditions
in special driving situations, e.g. airbag
deployment, intervention of stability con-
trol systems
R ambient conditions, e.g. outside tempera-
ture
This data is of an exclusively technical nature and can be used to:
R assist in detecting and rectifying faults and
defects
R analyse vehicle functions, e.g. after an acci-
dent
R optimise vehicle functions 28
Introduction

The data cannot be used to trace the vehicle's
movements.
When your vehicle is serviced, technical infor-
mation can be read from the event data mem- ory and fault data memory.
Services include, for example:
R repair services
R service processes
R warranty events
R quality assurance
It is read by employees of the service network (including manufacturers) using special diag-
nostic testers. More detailed information is
obtained from it, if required.
After a fault has been rectified, the informa-
tion is deleted from the fault memory or is
continually overwritten.
When operating the vehicle, situations are
conceivable in which this technical data, in
connection with other information (if neces-
sary, under consultation with an authorised
expert), could be traced to a person.
Examples include:
R accident reports
R damage to the vehicle
R witness statements
Further additional functions that have been
contractually agreed upon with the customer
allow certain vehicle data to be conveyed by
the vehicle as well. The additional functions
include, for example, vehicle location in case of an emergency. Copyright information

!
Depressing the brake pedal constantly
results in excessive and premature wear to
the brake pads.
When reversing the vehicle towards the
trailer, make sure there is nobody between
the trailer and the vehicle.
Couple and uncouple the trailer carefully. If
you do not couple the trailer to the towing
vehicle correctly, the trailer could become
detached.
When towing a trailer, your vehicle's handling
characteristics will be different in comparison to when driving without a trailer.
The vehicle/trailer combination:
R is heavier
R is restricted in its acceleration and gradi-
ent-climbing capability
R has an increased braking distance
R is affected more by strong crosswinds
R demands more sensitive steering
R has a larger turning circle
This can impair the vehicle's handling char-
acteristics. Adapt your driving style accord-
ingly. Maintain a safe distance. Drive care-
fully.
When towing a trailer, always adjust your
speed to the current road and weather con-
ditions. Do not exceed the maximum permis- sible speed for your vehicle/trailer combina-
tion. Notes on towing a trailer
General notes Trailer towing is not permissible on the fol-
lowing models:
R C 180 BlueEFFICIENCY Edition
R C 220 BlueTEC BlueEFFICIENCY Edition
When towing a trailer, set the tyre pressure on
the rear axle of the towing vehicle for a max-
imum load; see the tyre pressure table in the fuel filler flap (Y page 432). On vehicles without level control, the height
of the ball coupling will alter according to the
load placed on the vehicle. If necessary, use a
trailer with a height-adjustable drawbar.
You will find fitting dimensions and loads
under "Technical data" (Y page 477).
When towing a trailer, the ECO start/stop
function is deactivated. The èECO sym-
bol appears yellow in the multifunction dis-
play. For further information on the ECO
start/stop function; see (Y page 186).
Driving tips Observe the notes on ESP
®
trailer stabilisa-
tion (Y page 82).
The maximum permissible speed for vehicle/ trailer combinations depends on the type of
trailer. Before beginning the journey, check
the trailer's documents to see what the max- imum permitted speed is. Observe the legally
prescribed maximum speed in the relevant
country.
For certain Mercedes-Benz vehicles, the max-
imum permissible rear axle load is increased
when towing a trailer. See the "Technical
data" section to find out whether this applies
to your vehicle (Y page 478). If you utilise any
of the added maximum rear axle load when
towing a trailer, the vehicle/trailer combina-
tion may not exceed a maximum speed of
100 km/h for reasons concerning the oper-
ating permit. This also applies in countries in
which the permissible maximum speed for
vehicle/trailer combinations is above
100 km/h.
When towing a trailer, your vehicle's handling
characteristics will be different in comparison to when driving without a trailer and it will
consume more fuel.
Change into a lower gear in good time on long
and steep downhill gradients.
This also applies if cruise control, DISTRONIC
PLUS or SPEEDTRONIC are activated.
This will use the braking effect of the engine,
so less braking will be required to maintain
vehicle speed. This relieves the load on the 284
Towing a trailerDriving and parking

Roof carrier
Important safety notes G
WARNING
When a load is transported on the roof, the
vehicle's centre of gravity rises and the han-
dling changes. If you exceed the maximum
roof load, the handling as well as steering and braking characteristics are severely affected.
There is a risk of an accident.
Always observe the maximum roof load and
adapt your driving style.
The maximum roof load can be found in the
"Technical data" (Y page 476).
! Mercedes-Benz recommends that you
only use roof carriers that have been tested
and approved for Mercedes-Benz vehicles.
This helps to prevent damage to the vehi-
cle.
Position the load on the roof carrier in such
a way that the vehicle will not sustain dam-
age even when it is in motion.
Depending on the vehicle equipment,
ensure that when the roof carrier is fitted
you can:
R raise the sliding sunroof/panorama slid-
ing sunroof fully
R open the boot lid fully
! To avoid damaging or scratching the cov-
ers, do not use metallic or hard objects to
open them.
An incorrectly secured roof carrier or roof
load may become detached from the vehicle.
You must therefore ensure that you observe
the roof carrier manufacturer's installation
instructions.
Vehicles with panorama sliding sunroof: if
a roof carrier is fitted, the panorama sliding
sunroof cannot be opened. In order to allow
ventilation of the vehicle interior, you can
raise the panorama sliding sunroof.
If a roof carrier approved by Mercedes-Benz
makes contact with the panorama sliding sunroof, the sunroof will lower slightly but
remain raised in the rear.
Attaching the roof carrier X
Open covers :carefully in the direction of
the arrow.
X Fold covers :upwards.
X Only secure the roof carrier to the anchor-
age points under covers :.
X Observe the manufacturer's installation
instructions. Features
Cup holders
Important safety notes G
WARNING
The cup holder cannot secure a drinks con-
tainer in place during a journey. If you use a
cup holder during a journey, the drinks con-
tainer could be flung around and liquid could
be spilt. Vehicle occupants could come into
contact with the liquid and, in particular, be
scalded by hot liquid. You could be distracted
from the traffic situation and lose control of
the vehicle. There is a risk of an accident and
injury.
Only use the cup holder when the vehicle is
stationary. Only place containers of a suitable size in the cup holder. Seal the container, in
particular when it contains hot liquid. 376
